Blync
Blync is a browser-based AI invoicing application for freelancers, self-employed professionals, and small businesses. Users describe a job in plain English, review an invoice drafted with local tax details, edit it by chat, and choose when to send it. The service supports quotes that clients can accept online and convert into invoices, multi-currency billing, client payment pages, and configurable overdue reminders. Users can track paid and outstanding invoices and view accounts receivable, profit-and-loss, and cash-flow information based on invoices and expenses. Blync provides country-specific tax rates, tax-ID formats, invoice requirements, and tax exports for more than 50 countries. Drafting is available without an account; downloading, sending, or saving drafts requires a free account. Blync does not process client payments.

BillingHub
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.
