7 best project billing software tools for 2026
Choosing project billing software by feature list is how teams end up with a tool that invoices beautifully and still loses money. I work at Teamwork.com now, but I spent years running agency accounts, and the same lesson held: the billing model behind the invoice mattered more than the invoice itself. Clients are sharper on price than they've ever been, and they'll question an invoice the moment the value isn't obvious. That pressure punishes any team whose billing and delivery data don't line up.
