Wave
Wave wins for small-business invoicing in 2026. Unlimited invoices, recurring billing, payment acceptance via Stripe and PayPal, and basic double-entry accounting all on a genuinely free plan. Wave monetises through payment processing fees and optional payroll, not a per-seat invoicing charge - which is why it is the no-brainer pick for any business under $1M revenue that does not yet need an accountant-grade general ledger. FreshBooks is the best value at $19 a month for service businesses that want proper time tracking, expense capture, and client-portal proposals alongside invoicing. Bonsai is the runner-up for service businesses that want contracts, proposals, and invoicing combined in one tool.

Frequently Asked Questions
Wave is the best invoicing software for small business in 2026 for most operators. The free plan covers unlimited invoices, unlimited customers, recurring billing, automatic payment reminders, and built-in Stripe and PayPal payment acceptance - genuinely enough for any business under $1M revenue that does not yet need an accountant-grade general ledger.
Yes, the Wave Starter plan is genuinely free with unlimited invoicing, unlimited customers, and basic double-entry accounting. Wave monetises through payment processing fees (around 2.9 percent plus 60 cents per credit card transaction, on par with Stripe direct) and optional add-on payroll for US-based teams. There is no per-seat invoicing fee and no time-limited trial.
Wave wins for businesses that want pure invoicing plus payment acceptance plus light accounting without a monthly fee. FreshBooks wins for service businesses (agencies, consultants, contractors) that want time tracking integrated into invoices, expense capture with receipt photos, and a client portal for estimates and proposals. The decision is whether the FreshBooks $19-to-$33 monthly cost is justified by the project-management and time-tracking features.
For businesses under $1M revenue, Wave's built-in basic accounting is often enough - chart of accounts, income and expense tracking, and tax-ready reports. As the business grows past a part-time bookkeeper or hires a full-time accountant, QuickBooks Online becomes the accounting standard that accountants universally accept. Most businesses make the move from Wave or FreshBooks to QuickBooks somewhere between $500K and $2M in revenue.
Wave accepts USD, CAD, GBP, EUR, and AUD payments via Stripe and PayPal. FreshBooks and Bonsai support multi-currency invoicing with automatic exchange-rate handling on Plus plans and above. Stripe Invoicing supports 135-plus currencies through Stripe's underlying processing. For businesses with international clients, multi-currency support is now standard - the differentiator is exchange-rate transparency on the invoice line items.
Standard credit card processing through Stripe, PayPal, or built-in invoicing payment is roughly 2.9 percent plus 30 to 60 cents per transaction. For a $1,000 invoice that comes to roughly $29 plus a fixed fee. ACH bank transfers cost less (around 1 percent capped at $5 to $10 through Stripe or Wave) but settle in 3 to 5 business days versus instant card payment. For high-volume B2B invoicing, ACH is materially cheaper.
