BillingHub is invoicing billed by the invoice rather than by the month. Freelancers and small businesses create invoices, estimates and quotes in 156 currencies, send them as PDFs under their own branding, and take card payments through their own Stripe account. A credit is spent only when an invoice is issued – drafts, clients, PDF downloads, sending and received payments cost nothing, and estimates and quotes are always free. Credits are bought once and never expire. There is no monthly plan; the one optional yearly plan renews annually and is what carries recurring invoices and API access.
