6 Best Billing and Invoicing Software for Small Business (2026)

The short answer

Just starting? Use Wave or Zoho Invoice. Both are free and send real, professional invoices.

Take cards in person? Square. Bill clients for hours? FreshBooks. Accountant wants QuickBooks? Give them QuickBooks.

Free and paid invoicing apps compared: real prices, card rates and the catch with each.

Invoicing software does one job: gets you paid faster with less chasing. You don’t need to spend much for that. Two of the best options are free.

Here are the 6 worth looking at, what each one really costs and the catch. Prices come from each company’s own pricing page, and card processing (what you pay when a client pays by card) is listed separately because that’s where the real cost hides.

The 6 best billing and invoicing software picks

1.Wave

Best free invoicing

What it is
Free invoicing and bookkeeping for small businesses.
What it does for you
Sends unlimited invoices and estimates, tracks what’s paid and what’s late, and keeps your books in the same place.
What it costs
Starter is $0. Card payments cost 2.9% + $0.60 each (3.4% + $0.60 for Amex). Pro is $19 a month or $190 a year, adds automatic bank imports and drops the 60 cents on your first 10 card payments a month.
The catch
The free plan makes you enter bank transactions yourself.

Worth it? Yes for most freelancers and small shops. Free invoices plus free books is hard to beat.

2.Zoho Invoice

Best free invoicing with automation

What it is
A completely free invoicing app from Zoho.
What it does for you
Sends invoices and quotes, runs recurring invoices and sends automatic payment reminders so you don’t have to.
What it costs
Free. Zoho caps it at two users, three projects and 500 invoices a year.

3.Square Invoices

Best if you also take cards in person

What it is
Invoicing built into Square, the card reader and point of sale system.
What it does for you
Sends unlimited invoices and estimates, and puts your in-person and invoice payments in one place.
What it costs
Square Free is $0 a month. Card payments on invoices cost 3.3% + 30 cents on the free plan, or 2.9% + 30 cents on Plus at $49 a month per location. Bank transfers (ACH) cost 1%, with a $1 minimum.
The catch
The card rate on the free plan is higher than most, so big invoices get expensive.

Worth it? Only if you already use Square or take payments face to face. Otherwise Wave costs less per invoice.

4.FreshBooks

Best for billing by the hour

What it is
Accounting software built around invoicing for service businesses.
What it does for you
Tracks your time and expenses and turns them into polished invoices, with accounting reports on top.
What it costs
Lite is $23 a month (bill up to 5 clients), Plus $43 (up to 50 clients), Premium $70 (unlimited). There’s a 30 day free trial, and the pricing page shows an intro discount for the first few months.
The catch
The client limits are tight. Hit client six on Lite and you’re paying $43 a month.

Worth it? Only if you bill hours to a handful of clients and want time tracking built in.

See FreshBooks plans

5.QuickBooks Online

Best if your accountant uses it

What it is
Full accounting software with invoicing, from Intuit.
What it does for you
Handles invoices, bills, sales tax and reports, with room to grow.
What it costs
Simple Start is $38 a month (1 user), Essentials $85, Plus $140, Advanced $340. QuickBooks Free costs $0 but has no mobile app or app integrations. No annual contract.
The catch
It’s a lot of software (and a lot of money) if all you do is send invoices.

Worth it? Only if your accountant asks for it or you need full accounting. For invoices alone, it’s overkill.

See QuickBooks plans

6.Xero

A QuickBooks alternative

What it is
Cloud accounting software with invoicing.
What it does for you
Sends quotes and invoices, takes online payments and reconciles your bank transactions.
What it costs
Early is $27 a month, Growing $59, Established $97. The pricing page shows an intro discount for new signups.
The catch
Early only covers 20 invoices and 5 bills a month. Send more and you’re on the $59 plan.

Worth it? Skip it unless your accountant works in Xero. For a small business, Wave or QuickBooks is a better deal.

See Xero plans

How to pick invoicing software

Start with how your clients pay you.

If they mostly pay by bank transfer or check, card rates barely matter, so take the best free option (Wave or Zoho Invoice). If they pay by card, compare the card rate, because on a $2,000 invoice the difference between 2.9% and 3.3% is $8 every single time.

Then look at the limits. Client caps (FreshBooks), invoice caps (Zoho Invoice and Xero Early) and user charges are what push you to the next plan, usually right when business picks up.

Last, ask your accountant. If they work in QuickBooks or Xero, using the same thing can save you more in their bill than the software costs.

Features that actually matter

Automatic reminders for late invoices. Online payments, so clients can pay from the email. Recurring invoices if you bill monthly. A mobile app if you invoice from job sites.

Fancy templates and dashboards are nice. They won’t get you paid any faster.

Keep the money separate from your personal account too. These business bank accounts for freelancers make that easy, and our list of tools for entrepreneurs covers the rest of a lean setup.

FAQ

What is the best free invoicing software?

Wave and Zoho Invoice. Wave gives you unlimited invoices plus free bookkeeping. Zoho Invoice is free up to 500 invoices a year and adds automatic reminders and recurring invoices.

How much does it cost to accept card payments on invoices?

It depends on the app. Wave charges 2.9% + $0.60 per card payment. Square charges 3.3% + 30 cents on its free plan, or 2.9% + 30 cents on Plus.

Is FreshBooks worth it?

If you bill hours to a few clients and want time tracking, yes. Lite is $23 a month but only bills 5 clients, so check that limit first.

Do I need QuickBooks for a small business?

Not to send invoices. QuickBooks starts at $38 a month and makes sense when you need full accounting or your accountant asks for it.
