What is a promise ledger?
A worked example
Here is a ledger for a made-up software deal, as Customer Success would receive it. Each line is a commitment, who made it, where it is written down, and who owns the next step.
| Promise | Said by, and when | Written where | Status | Next step |
|---|---|---|---|---|
| Waive the setup fee | Account executive, on the pricing call, week 3 | Not in the order form | Still to confirm | Sales manager, before kickoff |
| Go live by the 15th of next month | Account executive, in email | Email only; the order form has no date | Still to confirm | Customer Success lead, scope it at kickoff |
| Monthly usage report built for their finance team | Account executive, on the product call | Not in the contract | Not in the contract | Customer Success lead, decide and quote |
| Ten user seats at the agreed price | Order form, section 2 | Order form | Agreed | Customer Success lead, set up at kickoff |
| Data import from their old tool | Account executive, on the last call | Not in the contract | Still to confirm | Implementation lead, size it this week |
Two of five promises are agreed or close to it, and three are not in the contract. That is exactly what the kickoff call should settle.

Steps 2 and 3 of our step-by-step sales to customer success handoff guide show when to build the ledger and when to check it against the contract.
A promise ledger is a dated list of commitments sales made, verbal or written. The useful ones are the items not in the contract: a discount that was “just this once,” a custom report the account executive sketched on a call, a go-live date that was never scoped.
Customer Success teams lose trust when they walk those back. They lose margin when they honor them blindly. The ledger exists so the kickoff conversation can say “agreed,” “still to confirm,” or “not found in the order form” — before anyone is surprised.
It is not a CRM activity log. It is not a legal redline. It sits next to the deal brief: the brief tells the story; the ledger lists the landmines. Together with a kickoff agenda and a warm intro email, it is the Closed-Won packet.
Kickoff Pack includes the ledger as a page, not a portal field. You keep the file. You can paste it into HubSpot, Pipedrive, or a shared doc. That’s the whole job.
