Commercial handover debt: the time you lose after the deal closes

A deal closes on Thursday. By Monday the delivery lead is rebuilding what was sold from a proposal, scope notes and an email about a discount they have never seen. That is commercial handover debt: what was sold never reaches delivery and billing in one piece, and the gap is paid back in rework, waiting and unbilled work.

Check your handover

One deal, twelve weeks

Nothing here is dramatic. Each gap is small, and each one is paid for in hours.

An invented example, not a client and not a forecast. Hours are rounded; the day rate is $250 an hour.

WhenWhat happensHours lost
ThuThe deal closes at $90,000 fixed fee. A discount on extra work was agreed by email. The client is to supply its data by week 3.0
MonDelivery rebuilds the job from the proposal, the scope notes and the email thread. Two people, a day each.16
Week 3The client asks for one more report. The team builds it to keep the client happy. It is never logged as a change.30
Week 5The client's data is late. The dependency was in the sales notes, not the delivery plan, so the plan is redone.12
Week 8Finance asks which milestone triggers the invoice. Nobody is sure, and the answer takes a day to find.6
Week 12The invoice goes out with a page of explanation. The client questions the extra report, and finance reworks it.10

74 hours nobody planned: $18,500 at $250 an hour, on a $90,000 job. No one made a mistake. The detail was never in one place.

A good handover is a record, not a meeting

A meeting can confirm a record. It cannot replace one. Four things need to be written down where delivery and finance can both see them.

  1. What was sold

    The scope, the exclusions and what the customer is actually buying.

  2. How it is delivered

    Milestones, tasks, budgets and the client's own obligations, matching the agreement.

  3. How change is handled

    New or extra work is logged and agreed commercially before it becomes normal effort.

  4. How it bills

    The rules and triggers, so every invoice can be explained from the record.

Is your handover a record or a meeting?

Four questions, answered for your firm as it works today. Nothing is stored or sent.

  1. Can a project manager see the sold scope, exclusions, assumptions and billing logic without hunting through documents?
  2. Can finance explain why an invoice is valid without relying on side conversations?
  3. Do changes to work get recorded commercially before they become normal delivery effort?
  4. Can leadership compare proposed margin, delivery reality and billing outcome on the same engagement record?

If the answer is no to one or more of these, the business is probably carrying more handover debt than it realises.

How DAY ONE carries the handover

The billing rules sit on the contract, and a rate off the price list shows as a discount and variance. A change is its own contract, approved by a named approver and recorded in the approval history. Draft invoices are built from approved time, ready milestones and approved expenses, and a person still approves them.

Questions about handover debt

Can't see your question? Ask us directly.

What is commercial handover debt?

It is what you owe when what was sold does not reach delivery and billing in one piece. Delivery pays it back in rework, waiting and unbilled work, and it builds silently because every team can keep working.

Is this the same as poor project management?

No. It is not poor project management, and it is not a finance clean-up issue. It is a structural problem in how commercial intent is translated into operational reality.

What does the research say?

McKinsey (2019) ties accurate scoping and disciplined handling of customer changes to margin capture. PMI links weak requirements and change management to worse project outcomes. APQC (2025) shows finance closes faster when upstream data quality is better. IFRS 15 asks for care with contract modifications when scope changes before price is settled.

Where does this show up in DAY ONE?

A change is its own contract, approved by a named approver, with the decision kept in the approval history. See Scoping and Quoting.
