Invoicing & payments

Create an estimate, a proposal or a contract

Everything you send before the work — and how it turns into an invoice afterwards.

IDup separates three documents that are often confused. An estimate is a priced offer. A proposal is the same plus the argument for it. A contract is what binds once they say yes.

Where to find itCRM → Sales → Estimates and Proposals; Sales & billing → Contracts.

Step by step

  1. Open Estimates (or Proposals) and create a new one for the customer or the lead.
  2. Add the lines, the tax and the validity date.
  3. Send it. The customer can accept or decline it from their portal, and their answer is recorded on the document.
  4. When it is accepted, convert it into an invoice — the lines come across rather than being retyped.
  5. If a signed agreement follows, create it under Sales & billing → Contracts, with its type, its dates and its renewal reminder.

Estimate requests

Sales & billing → Estimate request is the incoming side: a form a prospect fills in on your website that becomes a request you can price. It saves the first exchange of e-mails.

Statuses that mean something

  • Estimates: draft, sent, expired, declined, accepted.
  • Proposals: open, revised, sent, declined, accepted.
  • Contracts: active, expiring, expired — with a reminder before the date rather than after it.
