BillingHub is invoicing billed by the invoice rather than by the month. Credits are bought once, and one is spent only when an invoice is issued — drafts cost nothing, estimates and quotes are free on every plan, and credits never expire. The packs are one-time and never renew; an optional yearly plan is the only recurring item on the price list. Invoices go out as PDFs in 156 currencies with your own logo and no BillingHub branding, and there is no cap on clients, products or tax rates. Estimates and quotes are sent as a link the client accepts or declines online, and an accepted quote becomes an invoice. Payments are collected through your own Stripe account. The yearly plan adds invoices that repeat on a schedule and a REST API with idempotency keys plus outbound webhooks. There is also a free invoice generator that needs no account at all.
