Editorial guidance for this audience

What to look for when you're choosing invoicing software as a consultant.

Service billing and retainers

Look for software that supports recurring invoices for retainers, clear payment tracking, and professional invoice templates. FreshBooks and Bonsai both excel here; HoneyBook adds a full client pipeline; Wave keeps cost at zero.

Proposals and client management

Consultants often send proposals before invoicing. Bonsai and HoneyBook are built for proposals and contracts first, then invoicing. FreshBooks offers estimates that convert to invoices. Choose based on how formal your engagement process is.

Online payments

Payment links and online collection reduce follow-up and get you paid faster. All of our picks support online payments; compare fees and supported methods (card, ACH) when choosing.
