11 Best Billing Software for Small Business in 2026, Compared

FreshBooks is built around the invoice, and it shows. The Lite plan covers unlimited invoicing, estimates, expenses and time tracking for $23 a month, and the time you log flows straight onto the invoice without retyping. Recurring invoices and automatic reminders are included from the start, so repeat work chases itself.

The catch is the client cap. Lite covers five billable clients, and the sixth forces Plus at $43 a month, which is where bank reconciliation and accountant access also start. If your client list is short and stable, Lite is the cheapest billing-first tool here; if it grows past five, price Plus instead.

QuickBooks Online is the bookkeeping standard that happens to bill well. Simple Start costs $38 a month and includes unlimited invoices and bills, automated bank feeds, income and expense tracking and basic reporting, all on a double-entry ledger. It is the tool most accountants already know, which makes tax time and handovers easier.

The limits are seats and inventory. Simple Start allows one user, so a second person posting means Essentials at $85 a month, and inventory tracking waits for Plus at $140. Buy QuickBooks when you want invoicing and the books in one place; buy a billing-only tool when the books already live elsewhere.

Xero is the quiet pick for teams. Early costs $27 a month and includes unlimited users, so the whole team can post without a per-seat fee, plus bank reconciliation, Hubdoc receipt capture, quotes and recurring invoices. For a business sending under 20 invoices a month, that is a complete billing setup at a lower price than QuickBooks.

The cap is the thing to watch. Early allows 20 invoices and 5 bills a month, and regular volume above that means Growing at $59. Multi-currency and projects wait for Established at $97. Count your monthly invoices first; if you stay under 20, Xero is the best-value ledger here.

Wave is the only tool here that pairs unlimited free invoicing with free bookkeeping. Starter costs nothing and includes unlimited estimates, invoices, bills and bookkeeping records, plus recurring invoices and automatic payment reminders that rivals charge for. For a solo owner starting out, it is a real business setup at $0.

Free does not mean costless. Card payments on Starter cost 2.9% plus $0.60 per transaction, and bank entry is manual until Pro at $19 a month adds automatic imports. Wave is also limited to US and Canadian businesses. If you bill mostly by card, work out the processing fees before calling it free.

Zoho Invoice is the most generous free plan in this list. It costs $0 and includes the features other tools charge for: automated payment reminders, recurring invoices, a self-service customer portal, estimates, expenses and time tracking. The limits are 500 invoices a year, two users and three projects, which covers most freelancers comfortably.

The trade-off is the ceiling. There is no paid tier to grow into, so outgrowing the limits means switching to Zoho Billing, which starts at $25 per organization a month billed annually. Zoho also processes no payments itself, so your gateway charges its own fee. Start here while you fit; plan the move before you hit 500 invoices.

Square Invoices fits businesses that sell in person as well as online. The free plan sends unlimited invoices with automatic reminders and recurring billing, and the money lands in the same Square account as till sales. That single money view is the reason to pick Square over a standalone invoicing tool.

The price is the processing fee. Card payments on the free plan cost 3.3% plus $0.30 per invoice, and Square is the only processor you can use. Plus at $49 a month per location cuts the card fee to 2.9% plus $0.30 and adds payment schedules and custom fields. If most clients pay by card, compare the fee before the plan price.

HoneyBook sells the client journey, not just the invoice. Starter costs $36 a month on monthly billing, or $29 billed annually, and covers proposals, contracts, invoices, payments, a client portal and a calendar for unlimited clients and projects. A client can sign and pay from one file, which suits photographers, designers and coaches.

The entry plan is not the full flow. Workflow automations, the scheduler, SMS reminders and branding removal all sit on Essentials at $59 a month on monthly billing. Card payments also add 2.7% plus 10 cents per transaction. Buy HoneyBook for the proposal-to-payment flow; buy a cheaper tool if you only send invoices.

Invoice Ninja is the open-source option in this list. The free hosted plan gives unlimited invoices for up to 5 clients, with recurring billing, auto-billing, a client portal and dozens of payment gateways. Pro costs $14 a month and unlocks unlimited clients, 11 invoice templates and a branded portal URL, which is still the cheapest paid plan here.

The self-hosted edition is the real draw for technical owners: it is free, unlocks the Pro and Enterprise features, and has no client cap at all. The trade-off is that Invoice Ninja does no full bookkeeping, so the books need a separate tool. Pick it when you want control and a low bill, not a guided setup.

BILL, formerly Bill.com, is the only tool here that automates both directions of billing. Essentials costs $49 per user a month and covers accounts payable and receivable: supplier bills come in, approvals run, payments go out, and customer invoices go the other way. It syncs with QuickBooks, Xero, Sage and NetSuite, so nothing is retyped into the books.

Per-user pricing is the catch. A five-person team pays $245 a month before transaction fees, which makes BILL the priciest entry here for a team. It earns that price only when bill volume is high and approvals matter. If you only send invoices, a billing-only tool costs far less.

Chargebee is built for recurring revenue, and its 2026 pricing matches that job. The Flow plan charges 0.80% of monthly billing value with no platform fee and no contract, or $99 a month plus 0.65% on the commit variant. Subscriptions, usage billing, proration, trials, coupons and dunning all sit in one catalog, with more than 40 payment gateways to connect.

The percentage model is also the risk. A business billing $50,000 a month pays $400 a month on pay as you go, and the fee never stops growing with revenue. Chargebee also moves no money itself, so gateway fees sit on top. It fits subscription businesses that want billing to scale with sales, not a flat subscription.

Stripe Billing is the subscription layer inside Stripe, and it suits businesses already taking Stripe payments. Pay as you go costs 0.7% of billing volume with no recurring fee, and it covers subscriptions, trials, discounts, proration and Smart Retries. Setup runs through the Stripe Dashboard, Payment Links or Checkout, with no code needed for standard plans.

The fee stacks. Card processing at 2.9% plus $0.30 sits under the 0.7% billing fee, so a $20 subscription paid by US card costs about $1.02 in total fees. Stripe Billing also covers recurring charges only; one-off invoices use Stripe Invoicing at 0.4% per paid invoice. It is the simplest subscription pick for a Stripe shop.
