No installation, no per-document commission and unlimited drafts.
Acceptance without an accountCustomers respond through a secure link.
Convert without copyingKeep lines, prices, discounts and taxes.
Amounts made visiblePaid, outstanding and overdue at a glance.
Less repeated administration
Invoicing should not mean recreating the same document several times
When proposals, customers, invoices and payments live in separate places, duplicates, mistakes and uncertainty about each job quickly appear.
Copy concepts already included in an estimate all over again.Search email to find whether the customer accepted the latest version.Track payments and due dates in a separate spreadsheet.Lose the relationship between delivered work and its invoice.

Frequently asked questions
What matters before you start
How documents, quotas, payments and integrations work in Invoice.coffee.
FeaturesDoes a draft use the monthly quota?
No. Invoices count when issued and estimates count when sent.
Can a customer accept an estimate without registering?
Yes. They receive a secure link where they can accept or reject and add a note.
Can I change an estimate after sending it?
It is not overwritten. You can create a linked revision and retain the previous history.
Does a void invoice still count?
No. Invoices with void status are excluded from the monthly quota.
Can it receive operations from other applications?
Yes, when an active authorised connection exists within the same organisation.
