Software for small business, and how to pick one

Software for small business is not one purchase, it is a subscription stack that grows one plausible decision at a time. Each tool is defensible on its own and the total is what surprises people, usually in the first week of a month when four annual renewals land together.

Useful questions here are narrower: what to buy first, what to postpone, and which pricing model turns a small monthly figure into a large annual one.

Every price below came from the vendor’s own pricing page on 5 September 2026, taken at the standard rate rather than the promotional one. Introductory discounts on this shelf are steep and short, and comparing a discounted first year against a standard one is how budgets go wrong.

The numbers worth carrying into a decision

Seven figures that decide more than any feature comparison, all read on 5 September 2026.

• $50 to $200 a month covers the whole necessary stack for a services business under ten people, at standard prices with no promotional discounts
• $0 is a real price for accounting: Wave’s Starter tier carries unlimited invoices and bookkeeping
• $25 to $140 a month is the working range for paid small business accounting, from Xero Early at $25 to QuickBooks Plus at $140
• 2.9% plus 30 cents is the standard online card rate at Stripe, with no monthly fee, which for most businesses is the largest software-adjacent cost of all
• $7 to $20 per seat is HubSpot Starter, against a free CRM tier that carries 2 users and 1,000 contacts
• €11.90 per user per month is where full ERP starts on Odoo’s annual Standard plan, with one app free for unlimited users below that
• 90% off for six months was Xero’s live promotion on the day this was written, which is why the standard price is the only number worth budgeting

One pattern sits behind those figures: subscriptions are the small number, transaction fees and headcount-linked pricing are the large ones.

Software for small business: the order that costs the least

Small businesses tend to buy in the order that the loudest problem dictates, which is not the cheapest order. The pattern that works is to buy what the law and the bank require, then what is losing you money, then what is costing you time.

Priority	What it is	Realistic monthly cost	When to buy
1	Accounting and invoicing	$0 to $90	Before the first invoice goes out
2	Payments and a bank feed	Per transaction, not per month	With the first customer
3	Payroll	$0 to $80 plus per person	The month you hire someone
4	CRM	$0 to $20 per seat	When leads outlive your memory
5	Website	$0 to $40	Before you spend anything on ads
6	Project or job management	$0 to $15 per seat	When work is handed between people
7	Inventory or ERP	$12 per user upwards	When stock is counted rather than known
8	Password manager and backup	$3 to $8 per user	Sooner than anyone does it
9	AI assistance	Usage-based	Last, once there is something to automate

Two things about this order. Nothing below position four needs paying for in the first year for most businesses, and the free tiers at positions four to six are genuinely usable rather than crippled. The pressure to buy earlier comes from the vendors, not from the work.

Accounting, the anchor purchase

This is the one purchase where the free option is a real option and also the one where switching later hurts most, because history does not move cleanly between ledgers.

Tool	Standard price on 5 September 2026	What the tier limits
Wave	Starter free, Pro $19/month	Free tier covers unlimited invoices and bookkeeping; payments at 2.9% + $0.60 per card transaction
Xero	Early $25, Growing $55, Established $90/month	Early caps at 20 invoices and 5 bills a month; no per-user fees on any plan
QuickBooks Online	Simple Start $38, Essentials $85, Plus $140, Advanced $340/month	Users: 1, 3, 5 and 25 respectively, plus accountant seats

Read those tables by the unit, not the headline. Xero charges by document volume and includes unlimited users, so a five-person business on Growing pays $55 in total. QuickBooks charges by user, so the same five people need Plus at $140.

Neither is overpriced. They answer different questions, and cheap accounting software for small business is whichever one matches the shape of your team.

Three things decide this purchase more than features:

What your accountant already uses. An accountant fluent in one ledger and guessing in another costs you more in billable hours than the subscription saves. Ask before you subscribe, not after.

Whether inventory is part of it. Accounting and inventory software for small business is a genuinely different product from a plain ledger, and bolting stock control onto a tool that does not track it produces a spreadsheet that disagrees with the accounts. If you hold stock, this decision belongs here rather than at position seven.

Where the file has to end up. If you are on macOS and want a desktop application rather than a browser tab, the shortlist for small business accounting software for mac is short and worth checking before you fall in love with a web product’s interface.

Two categories that get mislabelled here. Project accounting software for small business is a job-costing feature, not a separate purchase, and most mid-tier plans have it. Accounting software for manufacturing small business usually means inventory plus bills of materials, which is the point where the conversation turns into ERP.

People search for the benefits of accounting software for small businesses and get a feature list back. The real ones are dull, and they are why this sits at position one: the bank feed reconciles itself, the tax figure is a report rather than an evening, and the invoice that is 45 days late is visible without anyone remembering to look.

Whatever you pick, the finance and accounting shelf is where the alternatives sit, and the free tiers are marked so you can start at zero and pay later.

Payments, the cost nobody puts in the software budget

Card processing is not usually counted as software spend, and for most small businesses it is the largest number in this article.

Stripe charges 2.9% plus 30 cents per successful online card payment on standard pricing, with no setup or monthly fee, plus 1.5% on international cards and 1% for currency conversion. Wave charges the same 2.9% plus 60 cents.

Platform fees sit on top. Shopify adds 2% on Basic when you use a third-party processor, dropping to 1% on Grow and 0.6% on Advanced.

Run the arithmetic against your own revenue rather than against the subscriptions. A business turning over $30,000 a month on cards pays roughly $870 in processing at 2.9%, which is more than every other tool in this article combined. Shaving that rate by even a third of a percent is worth more than cancelling four subscriptions.

Where the savings actually are:

• Bank transfer or direct debit for recurring invoices, which is priced far below card rates almost everywhere
• Local card acquiring if a meaningful share of revenue is international, since cross-border surcharges compound
• A platform tier that removes the third-party transaction fee, once the fee exceeds the tier upgrade
• Invoicing that does not route through a card at all for large B2B payments

Our payments and invoicing categories are separate for a reason: the processor and the tool that issues the document are different decisions, and bundling them is convenient rather than cheap.

Payroll, and the month it stops being optional

Payroll is the category where free is real and also where free stops abruptly.

Free payroll software for small business means one of three things: a calculator that produces figures you file yourself, a free tier capped at a very small headcount, or a module inside an accounting subscription you already pay for.

All three are fine at two or three employees. None of them survives the first multi-state hire or the first year-end filing you would rather not do by hand.

Paid tools here almost always charge a base fee plus a per-person fee. Wave prices payroll as an add-on from $25 a month on top of the subscription, and that shape is the norm: the base covers the filing machinery and the per-head charge covers each person on it.

Three things decide the purchase more than the price:

Filing, not calculating. The calculation is arithmetic. The value is in the tool filing with the tax authorities on time and taking responsibility when it does not. Ask directly whether filings are included or an extra, and in which states or countries.

Contractors as well as employees. Many small teams are a mix. A tool that handles employees beautifully and contractors as an afterthought means a second process every month.

The exit. Payroll history is legally required for years after somebody leaves. Check what an export contains before you need it.

Small business software with payroll built in, rather than bolted on, removes a monthly reconciliation between two systems. HR and payroll software for small business bundles add onboarding, time off and documents on top, and they earn the upgrade at about the point where somebody is spending a day a month on paperwork.

Deadlines here are set by the tax authority rather than the vendor. In the United States the IRS employment tax deposit schedule decides whether you deposit monthly or semi-weekly, and a tool that does not know which schedule you are on will eventually file late.

Options sit on the payroll shelf, and the HR and recruiting one holds the bundles.

CRM, and the point a spreadsheet stops working

A spreadsheet is an adequate CRM up to the number of open conversations one person can hold in their head, which is smaller than most people admit and roughly where the first deal is forgotten.

Free tiers here are unusually good. HubSpot gives 2 users and 1,000 contacts free with no card, and its Starter seats were listed at $7 per seat per month promotionally against a $20 standard rate on 5 September 2026. That is enough for a small sales operation to run for a year without paying anything.

What separates the best CRM for small business from an expensive address book is narrow:

Does it capture without discipline? A CRM that requires someone to log activity manually will be current for six weeks. One that reads the mailbox and the calendar stays current on its own.

Does it fit the shape of your sale? Repeat transactional business and long negotiated deals need different pipelines. Most small business CRM software is built for the second and used for the first.

How does it charge for growth? Contact-tier pricing is the trap here. The bill does not move when you hire, it moves when a marketing campaign adds contacts, which is exactly when you have least attention to spare.

Can you get the data out? A CRM export that omits notes and activity history is an address book export, and notes are the part that took two years to accumulate.

Free CRM software for small business is worth exhausting before you pay. The upgrade that is actually worth money is usually automation and reporting, not more contact records, and the honest test is whether a specific report you cannot produce today would change a decision. The CRM and sales shelf lists what is available, with free plans marked.

ERP, and what the word means at this size

Enterprise resource planning sounds like the wrong size of word for a nine-person business, and for a plain services business it is. ERP software for small business becomes relevant when three things are true at once: you hold stock, you make or assemble something, and the accounting no longer matches the warehouse.

At that point the alternative to ERP is not simplicity, it is four tools and a person reconciling them.

Odoo is the reference point for pricing here: one app free for unlimited users, then €11.90 per user per month on the annual Standard plan and €17.90 on Custom, read on 5 September 2026.

That “one app free” tier is why free ERP software for small business is a real search rather than a fantasy. Running inventory or manufacturing on a single free app, before committing to a suite, is a legitimate way to start.

Before starting an ERP project at this scale, check four things:

• Whether your accountant can work inside it, or whether it will have to sync to a ledger anyway
• What the implementation costs, since the licence is frequently the smaller number
• Whether the modules you need today are the ones on the free or standard tier
• How stock corrections are handled, because that is the workflow you will run weekly

Small business ERP software fails more often through implementation than through software. What works is one module at a time, in production, with the old process running in parallel until the numbers agree twice.

Both the ERP and inventory shelves are worth reading before committing, because half the businesses that think they need the first only need the second.

Inventory, and the point a spreadsheet stops being safe

Stock is the one part of a small business where a spreadsheet does not merely become inconvenient, it becomes wrong in ways nobody notices for a quarter.

Failure arrives the same way every time. Two people edit different copies, a return goes back into the sheet but not into the accounts, and the count at the end of the year disagrees with the ledger by an amount that has to be written off.

Signals that the spreadsheet has run out:

• Stock exists in more than one place, including a van or a consignment shelf
• The same item arrives at different costs and margin has to be calculated per batch
• Somebody is manually keeping a marketplace listing in step with the shop
• A physical count has disagreed with the sheet twice

Inventory and accounting software for small business, bought as one product, avoids the reconciliation entirely. Bought as two products, it needs a working integration, and “has an integration” and “has an integration that handles returns and partial shipments” are different claims worth testing in the trial.

The website, bought later than it should be

A website is cheap, fast to launch and routinely postponed while money goes into advertising that lands on nothing.

This category is mature enough that the choice is mostly about what you plan to add. A builder that publishes pages quickly is enough for a brochure site. If you will sell, take bookings or publish regularly, check what those cost on top before choosing, because the entry price and the price with the features you need are rarely the same plan.

Transaction fees separate the tiers. Squarespace charges 2% on online store sales on its Personal plan and nothing on Business and above, and takes 7% on digital content and memberships at the entry tier.

Shopify’s third-party processing fee falls from 2% to 0.6% across its plans. On any meaningful volume those percentages decide the plan, not the feature list.

What the best website builder for small business needs to do, in the order it matters: load quickly on a phone, let somebody who is not technical change the opening hours, produce pages a search engine can index, and export or redirect cleanly if you leave.

That last one is the check people skip. Ask what happens to your URLs if you move the site elsewhere in three years, and get an answer before you have fifty pages worth of links pointing at them. Options live on the website builders shelf, and the ecommerce one if you are selling rather than publishing.

Project and job management

This fills a narrower gap than “we need a to-do list”. It is work being handed from one person to another and something being dropped in the handover.

There are two shapes here and they are not interchangeable. Board-and-task tools organise internal work: marketing, product, anything where the unit is a task. Job or field management tools organise work with a customer, a site and a scheduled time attached, and they carry quoting, dispatch and invoicing that a task board does not.

Construction project management software for small business is squarely the second kind, and buying the first kind for that job produces a beautiful board that nobody on site opens.

Both are cheap relative to everything else here, and both have usable free tiers under about five people. The project management and field service shelves separate them.

What the stack looks like by trade

Ordering at the top of this article is the general case. What sits at position seven changes a lot by what the business actually does.

Trade	The one purchase that matters most	What gets skipped safely	Where the money leaks
Professional services	Accounting with time and job costing	Inventory, ERP	Unbilled hours
Retail with a shop	Point of sale tied to inventory	CRM in year one	Card processing rates, stock shrink
Ecommerce	Platform plus inventory sync	Traditional CRM	Platform transaction fees
Construction and trades	Job management with quoting	Marketing automation	Quotes that never become invoices
Restaurant and hospitality	Point of sale plus scheduling	ERP, project management	Labour scheduling against covers
Light manufacturing	Inventory with bills of materials	Marketing tooling	Batch costing done by hand
Agency and creative	Time tracking and project accounting	Inventory, ERP	Scope creep on fixed-price work

Two patterns repeat across every row. The tool that touches money directly earns its price fastest, and the leak is almost never in the category people shop for first.

Where a trade needs a shelf of its own, the catalogue splits it: point of sale and retail, scheduling and booking, workforce management for shifts, and time tracking for the hours that turn into invoices.

Three worked monthly totals

Standard prices, no promotions, September 2026. These are illustrative arithmetic on published rates, not quotes.

	One person, services	Five people, services	Twelve people, retail with stock
Accounting	Wave Starter, $0	Xero Growing, $55	Xero Established, $90
Payroll	Not needed	Wave Payroll, $25 plus per person	Bundled HR and payroll, $80 plus per person
CRM	HubSpot free, $0	HubSpot Starter, 3 seats at $20, $60	HubSpot Starter, 5 seats, $100
Website	Builder entry plan, $16	Builder business plan, $23	Ecommerce plan, $56
Inventory or ERP	Not needed	Not needed	Odoo Standard, 6 users, about $77
Project or job tools	Free tier, $0	Free or entry tier, $40	Entry tier, $96
Passwords and backup	$3	$25	$60
Subscriptions total	about $19	about $228 plus payroll per head	about $559 plus payroll per head
Card processing at 2.9%	On $8,000: $232	On $40,000: $1,160	On $120,000: $3,480

That last row is the point of the table. In all three columns the processing fee is larger than every subscription combined, and it is the line nobody reviews.

Six ways the bill grows without a decision

Each of these appears in this stack repeatedly, and none of them shows up as a purchase.

The promotional cliff. Discounts of 50 to 90 percent for three to six months are standard here. Xero’s listed offer on 5 September 2026 was 90 percent off for six months. Nothing is wrong with taking one, as long as the number in your budget is the standard price and the renewal date is in a calendar.

The user you added in March. Per-user tools grow silently with headcount, and nobody re-examines the plan when the fourth seat pushes you past a tier boundary.

The annual prepay. Paying yearly saves real money and removes the monthly moment when somebody notices a tool nobody uses. Prepay the two tools that are load-bearing, keep the rest monthly for the first year.

The overlap. Three tools with a built-in CRM, two with invoicing, two with time tracking. It happens because each was bought for a different reason and each was right at the time. An annual review of what each subscription is actually used for tends to find one full cancellation.

Contact-tier creep. Marketing tools priced by contacts grow when a campaign works, which is the worst possible moment to discover a tier boundary. Set a contact ceiling and clean the list against it.

Usage-priced AI. Credits, generations and resolutions are consumed by other people’s behaviour rather than by your decisions. Every one of them needs a cap before it is switched on.

The four tools people skip and regret

None of these is exciting and all four are cheap relative to what they prevent.

A password manager. Shared logins on a spreadsheet is how a business loses an account it cannot recover, usually when the person who set it up has left. Around $3 to $8 per user per month, and it takes an afternoon.

Backup that is not the same account as the data. Cloud tools are not backups: a deleted folder syncs the deletion everywhere. Anything holding customer records or accounts needs a copy somewhere else.

Electronic signature. Cheap, and it removes days from every contract cycle. The free tiers cover a handful of documents a month, which for a small business is often enough.

Two-factor on the money accounts. Free, and the single highest-value security decision on this list. Bank, payment processor, accounting, domain registrar, email.

Those live on the password managers, backup, e-signature and security shelves, and all four have credible free tiers.

AI tools, and where the bill hides

AI tools for small business are the newest line on the invoice and the one that behaves least like the others. The rest of this stack charges by seat or by month. AI charges by use, and use is decided by your customers and your staff rather than by a decision you made when signing.

Three shapes are worth separating.

Included features are an AI label on something you already pay for: a draft suggestion in the CRM, a category guess in the accounting tool. These are free and occasionally useful, and they are the ones to try first.

Metered add-ons charge per generation, per resolution or per credit pack. The number to establish before turning one on is what happens when the pack runs out, and whether you can cap it.

Standalone subscriptions for a specific job. AI content creation tools for small business and AI SEO tools for small business are the two categories where a standalone purchase is most often justified, because they replace an hourly cost rather than adding a feature.

Buy these last, and buy them against a task somebody is currently doing by hand for a measurable number of hours. The best AI tools for small businesses 2026 has to offer still carry a labour cost: somebody checks the output, and that time is part of the price.

Our AI tools shelf marks which have free tiers, and AI writing separates the drafting products from the rest.

Switching later: what moves and what does not

Every tool on this list is easier to enter than to leave, and the difficulty varies enormously by category.

Category	How hard to leave	What usually does not come with you
Website builder	Hard	Page URLs, design, anything built with proprietary blocks
Accounting	Hard	Reconciliation history, attachments, prior-year locks
Payroll	Medium	Filing history in a usable format
CRM	Medium	Notes, activity timeline, custom field structure
Inventory or ERP	Hard	Batch costs, bills of materials, stock movement history
Project tools	Easy	Comments, attachments, board structure
Password manager	Easy	Almost nothing, exports are standardised

Both get cheaper with two habits. Run the export in the first month, while you have nothing to lose, and keep your own domain pointed at anything customers link to. Everything else is recoverable.

What to check in a trial

• Import your own data, not the sample set, including the messy historical part
• Add the second and third user and re-read the invoice
• Run the export on day two and open what comes out
• Find the standard price, not the promotional one, and put the renewal in a calendar
• Check what a mobile phone can do, since half of this work happens away from a desk
• Ask your accountant about anything touching the ledger before the trial ends
• Price the transaction fees, not only the subscription, if money moves through the tool
• Cancel one thing you are already paying for, to see how hard leaving is

Where to start

The shortest honest version: get the accounting right, price your card processing properly, add payroll when you hire, use the free tiers of everything else for a year, and revisit in twelve months with a list of what each subscription actually did.

The finance, payroll and CRM sections of the catalogue list what is available in each of these, with free tiers marked and no paid placement anywhere in the ordering. Every outbound link carries rel="nofollow" and nobody can buy a position, which is the only thing that makes a list like this worth reading.

Before you commit to anything annual, read the pricing page the way it deserves. The five things a SaaS pricing page hides are all present in this category, and the seat minimum and the usage ceiling catch small teams hardest.

And if a comparison site tells you one of these is the clear winner, read how software directories actually work before treating that as neutral.

Questions people actually ask

What software does a small business actually need in the first year?

Accounting, a way to take payments, and payroll from the month you hire. Everything else can run on a free tier or a spreadsheet for twelve months without costing you anything real. The businesses that overspend in year one almost always did it on tools for problems they did not have yet.

How much should a small business spend on software each month?

For a services business under ten people, roughly $50 to $200 a month covers everything necessary at standard prices, most of it accounting and payroll. Businesses holding stock spend more because inventory tooling starts higher. If the figure is well above that and there is no warehouse, the cause is usually overlap rather than any single expensive tool.

Is free accounting software good enough?

For invoicing, expense tracking and a bank feed at small volumes, yes. Wave’s free Starter tier covers unlimited invoices and bookkeeping. The point where free stops being sensible is multi-currency, inventory, or an accountant who charges you more to work around it than the paid plan costs.

Should I buy tools separately or take one suite?

Separately, early on. Suites make sense when the reconciliation between tools is costing someone real time each month, and that point arrives later than suite vendors suggest. The cost of a suite is not the price, it is that every renewal becomes one renewal you cannot walk away from in pieces.

What is the difference between ERP and accounting software for a small business?

Accounting software records what happened to the money. ERP coordinates what happens to stock, production and orders, and posts the money as a consequence. If you can count your inventory in your head, you do not have an ERP problem yet.

When is a CRM worth paying for?

When a deal has been forgotten, or when more than one person needs to know what was last said to a customer. Before either of those, a free tier or a well-kept spreadsheet is genuinely sufficient, and the paid upgrade should be triggered by a report you need rather than a contact limit you hit.

Do I need payroll software for two employees?

Not necessarily, but the filing obligations are the same as for twenty. Free payroll software for small business covers the arithmetic at that size. Paid tools become worth it at the point where somebody else taking responsibility for on-time filing is worth $30 to $50 a month.

How do I avoid paying for software nobody uses?

Put every subscription and its renewal date in one document, with the name of the person who asked for it. Review it once a year, before the biggest renewal rather than after. Almost every small business doing this for the first time finds at least one live subscription that nobody has opened in six months.

Are the promotional discounts worth taking?

Yes, provided the standard price is what goes in the budget and the renewal date goes in a calendar the day you sign. Xero’s 90 percent discount for six months is real money. It becomes a problem only when the seventh month arrives and nobody had planned for the full price.

Should I pay annually or monthly?

Annually for the two or three tools you are certain about, monthly for everything else during the first year. Annual prepay saves real money and removes the monthly reminder that a tool exists, which is exactly how unused subscriptions survive. Split the difference rather than picking one rule for everything.

What is the cheapest way to take card payments?

There is no single answer, because the rate depends on volume, card mix and whether payments are online or in person.

What holds up: bank transfer and direct debit cost a fraction of card rates for recurring invoices, cross-border cards carry a surcharge everywhere, and a platform’s own processor beats a third-party one on the same platform. Price it against your actual volume.

How do I know when to move off the free tier?

When a limit is changing your behaviour rather than annoying you. Working around an invoice cap by issuing documents elsewhere, or splitting a contact list across two accounts, costs more in time and errors than the paid plan. A limit you notice once a month is fine; a limit you plan around weekly is a purchase.
