Make Your Invoice Online — FreeMore Than an Invoice Maker
The same editor behind the invoice maker powers a dedicated generator for every document in your billing workflow:
Quote Generator
Send a priced, professional offer before the work starts — convert it to an invoice when the client says yes.
Receipt Generator
Confirm a payment was received with a clean, itemized receipt your client can file.
Purchase Order Generator
Authorize a purchase with a formal PO that states quantities, prices, and terms up front.
Credit Note Generator
Issue a refund or correct a billing error against a previously sent invoice.
Multiple Document Types
Generate invoices, quotes, receipts, purchase orders, and credit notes — all from a single, unified tool with the correct labels for each.

One Invoice Maker, Every Billing Document
Most billing happens in stages: you quote the work, invoice it when it's done, and receipt it when payment lands. Some clients also want a purchase order before anything starts, and occasionally you need a credit note to fix a billing error. A typical online invoice maker only covers the middle step — InvoiceGen covers all of them with the same editor.
Switch the document type and everything adjusts automatically: a quote gets a Quote # and a valid-until date instead of a due date, a receipt records the payment, a purchase order states quantities and terms up front, and a credit note references the invoice it corrects. Your line items, client details, logo, and currency settings carry the same look across every document, so your paperwork stays consistent from first quote to final receipt.
That continuity is the real time-saver. Won the job? Open the quote you sent, switch the type to invoice, and the numbers are already there. Payment arrived? Issue a receipt with the same details in seconds. Not sure which document a situation calls for? Our guide to invoice vs receipt vs quote breaks it down.
