The 5 best tools for small businesses, ranked

1QuickBooks Online

$0 (limited free tier)/mo · has a free plan

The default choice for small businesses that plan to grow: scales from the $20/mo Solopreneur plan to 25 users on Advanced, with payroll, inventory, and 750+ integrations. It’s also what accountants use, which makes the year-end handoff painless.

Watch out: Six straight years of price increases (Plus is now $140/mo); the learning curve is real.

2Xero

$27/mo/mo

The best QuickBooks alternative for teams: unlimited users on every plan with no per-seat fees, genuine multi-currency support, and the cleanest bank reconciliation reviewers praise. Strong pick if you collaborate or invoice internationally.

Watch out: Early’s 20-invoice cap pushes most businesses to the $55/mo Growing plan; US payroll is a paid add-on.

3FreshBooks

$23/mo/mo

If your small business is service-based and you value simplicity over accounting depth: the easiest invoicing here, with time tracking that flows into invoices. Good until your books get complicated.

Watch out: Client caps (5 on the $23 Lite plan) and $11/mo per extra team member — it’s solo-optimized, not team-optimized.

4Wave

$0/mo · has a free plan

The $0 foundation: unlimited invoices plus real double-entry bookkeeping, free. Sensible while you’re small and solo; many businesses start here and upgrade when payroll or multi-user access forces the issue.

Watch out: No payroll, no time tracking, and payouts limited to US/CA banks — you’ll outgrow it.

5Square Invoices

$0/mo · has a free plan

For businesses that sell in person as well as online: free unlimited invoices with built-in card payments and Square’s POS ecosystem behind it. Natural fit for retail, food, and service businesses with a physical presence.

Watch out: Card processing fees are uncapped, so costs scale with revenue; weak for pure office-based businesses.

How we ranked these

Unlike our freelancer rankings, this list scores tools on what matters when you have a team: multi-user support and per-seat costs, payroll and inventory options, accountant compatibility, and whether the tool scales or forces a painful migration later.

Frequently asked questions

What’s the best invoicing software for a small business (not a solo freelancer)?

QuickBooks Online for most: it scales from solo to 25 users with payroll and inventory, and accountants expect it. Xero is the best alternative — unlimited users with no per-seat fees and real multi-currency. Choose FreshBooks only if you’re service-based and prioritize simplicity.

How is “small business” invoicing different from freelancer invoicing?

Teams change the math: you need multiple users (per-seat fees add up), payroll, and usually inventory or project tracking. Solo-focused tools like FreshBooks get expensive or limiting with staff; QuickBooks and Xero are built for that transition.

Can a small business start free and upgrade later?

Yes — Wave’s $0 plan covers unlimited invoices and bookkeeping while you’re small. The usual upgrade triggers are hiring (payroll), adding collaborators (multi-user), or getting an accountant. Starting free doesn’t lock you out of QuickBooks or Xero later.

Do I need QuickBooks if I have an accountant?

Ask your accountant first — most US accountants work in QuickBooks Online, and matching their software saves billable hours at year-end. If your accountant prefers Xero (common outside the US), follow their lead.
