The original quote may no longer tell the whole story
Take a presentation project. The quote covers one version and a round of feedback. During the work, the client requests a shorter version for the sales team. You agree to add it, but the conversation stays in chat while the quote is in email. At invoicing time, you have to recover both to explain the price difference.
You don’t need new project software for this. You need one place that links to the current agreement, approved changes, and delivered files. It could be a client note or a card in the system your team already uses.
What a completed project record can look like
This example follows the presentation project. In your own record, add links to the specific messages and file versions. Copy prices from the client agreement; the record does not decide the price for you.
| What to save | Presentation example |
|---|---|
| Original scope | Presentation for management and one feedback round; link to the accepted quote |
| Agreed change | Additional short version for the sales team; link to the message approving the extra charge |
| Still undecided | Client is considering another language; price and timing are not yet agreed |
| Delivered work | Links to the main presentation and sales version, with delivery dates |
| Basis for invoicing | Quoted price plus the agreed extra charge; description of both completed deliverables |
An extra request is not yet an agreed change
The difference between “the client asked” and “we agreed” is easy to lose in a long thread. If someone asks about another language version, record it as an open question for now. Include it in the invoicing information according to the actual agreement, not simply because a colleague has started work.
Capture the change while you are discussing it: what is being added or removed, the effect on price and timing, and where approval is recorded. After a call, send a short recap to the participants. Until they respond, you have a record of your understanding—not certainty that everyone shares it.
At invoicing time, compare instead of reconstructing
Return to the record and open the latest agreement alongside the delivered work. For every invoice item, you should be able to show what it covers and where the amount came from. In this example, that means the main presentation and the agreed shorter version; the possible additional language stays out.
After sending, add a link to the invoice and its delivery message. Don’t duplicate payment tracking if you already maintain it reliably elsewhere. The record should help you and a colleague explain the project, not create another place to update the same data by hand.
