The best invoicing software for small businesses in 2026

The best invoicing software depends on your fees and your volume. Zoho Invoice and Wave suit people who want free invoicing, FreshBooks suits those who want a polished paid tool, Invoice Ninja suits technical users, and an all-in-one client portal suits businesses that also send quotes and contracts.

Picking invoicing software feels like a small decision until you do the arithmetic. A 3% gap on a $4,000 project is $120, every time. Over a year of steady work that is real money, and most people never compare the numbers side by side. Prices below come from each vendor's own page, checked in October 2026, and they change, so confirm before you buy.

What to compare

The monthly price is the part everyone looks at, and it usually matters least. Processing fees, client limits and whether recurring billing is included move more money over a year than a $10 monthly difference. In rough order of impact:

1. Processing fees on what clients pay. A flat monthly price is predictable. A percentage of every invoice scales with your income.
2. Payment methods. Cards are standard. Bank transfer, PayPal and local methods matter when clients are in different countries.
3. Recurring billing and multi-currency. Retainers need auto-billing. International work needs invoices in the client's currency.
4. Setup effort. Some tools are full accounting suites you have to learn. Others let you send an invoice in two minutes.
5. Client limits. Several free or cheap plans cap how many clients you can bill.

For the invoice itself, our guide on what to include on an invoice to get paid faster covers line items, terms and the details that cut payment delays.

Free and near-free: Wave, Zoho Invoice, Invoice Ninja

Three tools cover the basics at no monthly cost. The catch is either a client limit or the fee when a client pays by card.

Wave has a free Starter plan and a Pro plan at $19 a month ($190 a year). Wave's pricing page lists card payments on Pro at 2.9% with no flat fee for the first 10 transactions each month, then 2.9% + $0.60, and 3.4% for American Express. Starter's online payments add-on starts at 2.9% + $0.60 per card payment. Wave fits a solo owner or small shop that wants invoicing with light bookkeeping underneath.

Zoho Invoice describes itself as 100% free online invoicing software for small businesses, with no advertising, recurring invoices and a self-service portal where customers can view invoices and quotes and pay. If you grow, the pull toward the wider Zoho ecosystem is real, so check the current limits for your region before relying on it.

Invoice Ninja is for people who want control. Its Free plan allows up to 5 clients with no limit on invoices, and Pro is $14 a month or $140 a year for one user. You can also self-host it, and a white-label option costs $40 a year. Technical and privacy-minded users like that. Most people won't want to run a server.

Our free invoicing tool comparison goes deeper on these three.

Best for: Wave if you want free invoicing plus bookkeeping. Zoho Invoice if you want a free tool with a portal. Invoice Ninja if you want control or self-hosting.

Paid all-rounders: FreshBooks and QuickBooks

FreshBooks and QuickBooks cost more because they double as accounting software. Taxes, reports and expenses are better covered than in the free tools. The question is whether you need that depth.

FreshBooks lists Lite at $23 a month for 5 billable clients, Plus at $43 for 50 clients and Premium at $70 for unlimited clients, on monthly billing, with promotional discounts for the first months. Watch the client cap: a growing business can pass 5 clients quickly and jump to the $43 tier. FreshBooks is strong on the invoicing experience itself, with proposals, time tracking and clear client messaging.

QuickBooks is the heavyweight and is priced for accounting, not just invoicing. It makes sense if your accountant already uses it or your books are complicated. If you only send a few invoices a month, you pay for an accounting engine you won't use.

Best for: FreshBooks if you want a polished invoicing experience and can live within the client cap. QuickBooks if your accountant works in Intuit's world.

The fee nobody budgets for

The processing fee is the biggest cost most people ignore, and you pay it on every invoice for the life of the business. On $4,000 of card invoices a month, a 3% fee comes to $1,440 a year.

PayPal's business fees page lists domestic invoicing at 3.49% + a fixed fee for PayPal Checkout and Venmo, 2.99% + a fixed fee for cards, and 1% capped at $10 for Pay by Bank (ACH). The fixed fee is $0.49 per transaction in USD, and international invoicing adds 1.50% on top. Stripe and other gateways publish their own rates, and the pattern is similar: cards cost the most, bank payments the least.

Two questions matter more than the headline rate. First, can your client choose a cheaper method like a bank payment, or does the invoice default to a card? Second, who sits between you and the gateway? Some tools add their own cut on top of the gateway fee. Always read the fee line, not just the monthly price.

Recurring billing and multi-currency

If you bill retainers or work with clients abroad, recurring billing and multi-currency support are requirements. Most serious tools handle both, but free tiers vary.

Recurring billing sends and charges an invoice on a schedule, which is what monthly retainers need. Zoho Invoice lists recurring invoices, and FreshBooks and QuickBooks include them on paid plans. If retainers are your core income, confirm the tool can also charge a saved card, not just resend the invoice.

Multi-currency is the bigger divider. Billing in euros or pounds while your books stay in dollars sounds simple, but some cheaper tools only bill in one currency. Our piece on multi-currency invoicing covers what each option costs and how to avoid losing money on conversion. A quick rule: if more than a quarter of your clients are abroad, test multi-currency before you commit, because the conversion cost can quietly exceed the subscription.

All-in-one client portals

A fourth category bundles invoicing into the whole client workflow: quotes, contracts, file delivery, approvals and payment in one branded space. For a business that manages the whole relationship, one tool can replace three or four subscriptions.

The trade-off is commitment. You learn a whole workflow, not an invoice form, and if you only send invoices you pay for features you won't touch. But if you email contracts from one app, files from another and invoices from a third, consolidation often wins, and the client gets one place to work with you instead of five threads.

How Delivvo handles invoicing

Delivvo's invoicing is part of a chain that starts with an inquiry and ends with delivery, so the invoice is created from the accepted quote, not typed again.

1. When a client accepts a quote, the invoice and payment schedule are created automatically from it. You don't re-enter line items.
2. Invoice numbers are sequential in your own format. Invoices can carry a Tax Invoice title, a reverse charge note and your tax details, and you can void one or issue a credit note. Tax rules differ by country, so check the setup with your accountant.
3. Payment schedules split a total into up to 12 payments, which covers deposits, milestones and instalments.
4. Recurring invoices handle retainers on a schedule.
5. Late payment reminders go out at 7, 14 and 30 days and stop the moment the invoice is paid.
6. Clients pay through your own payment processor: Stripe, PayPal or Square.

Delivvo takes 0% and is never the merchant of record, so what you pay is your gateway's fee and nothing on top. Every invoice and receipt carries a verification code that shows the issuer, number, amount and status when checked at delivvo.io/verify.

Two limits to know: paying through a link from another gateway and uploading a bank transfer receipt are not built yet. You can try the invoice editor before signing up with the free invoice generator, then see the full flow on the invoicing page. Plans start at $0 with no card.

Next, look at how payments work or how the CRM fits around it.

Which one to pick

There is no single winner. Line up cost, fees and workflow and the matchups are clear.

If you want the tightest budget and simple needs, start with Zoho Invoice or Wave. If you want a premium invoicing experience and can live within the client cap, FreshBooks fits. If your accountant uses Intuit, QuickBooks follows. If you want to self-host, pick Invoice Ninja. If invoicing is one tab among quotes, contracts and delivery, choose an all-in-one portal like Delivvo.

Before you sign up, do the one calculation almost nobody does: take your average monthly invoicing total, apply the processing fee and multiply by twelve. That figure, not the subscription, is the real cost of getting paid.
