Invoicing & billing
Invoicing & billing software for practices
Turn an appointment into a professional invoice in a click — add items, tax and discounts, send it by email or a public link, and track exactly what has been paid.
Quzek billing is built for practices: create an invoice straight from an appointment, add services, products or session packs, apply tax and promo codes, and send it however your client prefers. Every invoice can be emailed (queued and logged), downloaded as a PDF, or shared as a secure public link, with payments and balances tracked automatically.
