Cost to get paid: 1% platform fee on online payments — passable to clients

Free invoicing and accounting

Best for simple accounting + invoicing

Cost to get paid: Standard payment processing fees apply

Square Invoices

Free plan available

Best for in-person + online sellers

Strong for retail and POS-connected businesses; service fees can be added in some cases, but it isn't built around agency quote-to-cash.

Zoho Invoice

Free invoicing

Best for a free standalone invoice maker

Genuinely free and full-featured for invoicing, but part of the wider Zoho suite and without surcharging or profitability tracking.

Invoice Ninja

Free tier + open source

Best for open-source / self-hosting

Flexible and developer-friendly with optional fee pass-through, but the setup and UX lean technical compared with a managed platform.

Cost to get paid: Gateway fees; can add a gateway fee to clients

Free invoicing software FAQ

What is the best free invoicing software?

The best free invoicing software depends on your needs. Wave and Zoho Invoice are strong for simple, genuinely free invoicing; Square suits sellers with in-person payments; Invoice Ninja fits self-hosting. Tillage is the best fit if you want free invoicing where you keep 100% — clients cover the card and platform fees — plus quoting and profitability tools.

Is free invoicing software actually free?

The software itself is usually free, but accepting card or bank payments carries processing fees (typically around 2.9% + $0.30 per card transaction). Most tools pass those fees to you. Tillage lets you pass both the processing fee and its 1% platform fee to the client at checkout, so you receive the full invoice amount.

Can I pass credit card fees to my clients?

Sometimes. Surcharging and convenience-fee rules vary by tool and by state. Many free invoicing tools don't support it. Tillage grosses up the invoice so the client covers the card/ACH fee and the 1% platform fee, letting you keep 100% — within the applicable card-network and legal limits.

Do free invoicing tools include quotes and contracts?

Most don't. Free invoicing tools focus on billing. Tillage connects quoting, contracts, and invoicing in one workflow — an accepted quote seeds the contract and the invoice schedule — so you don't re-key data between tools.

Free invoicing where you keep 100%

Send unlimited invoices, pass the fees to clients, and get paid faster. Free at $0/month — no credit card required.
