Here is the short version. Time is the hoster's most underused asset in a SPLA audit, because the auditor's opening timetable is built for their convenience, not your accuracy. Buying time legitimately, through scope, sequencing, and reasonable cooperation, lets you reconstruct your real position before the number is set rather than after.
Why the clock favors the auditor at first
The opening letter usually proposes a tight schedule and a broad data request in the same breath. That combination pressures you into producing raw infrastructure data fast, which is exactly the data that reads high. Speed serves the auditor. Accuracy serves you. The whole game in the early phase is to convert their speed into your accuracy without ever refusing to cooperate.
The legitimate levers that create time
You are not stalling. You are exercising the reasonable cooperation the agreement actually requires, on a timetable that lets you respond accurately. The levers are well established:
- Agree the scope in writing first. A defined product and period scope is faster to satisfy and slower to expand, and agreeing it takes time that you use productively.
- Require written, specific data requests. Each request that has to state product, month, and purpose is a request that takes the auditor longer to frame and gives you a clean basis to prepare a complete answer.
- Nominate a single point of contact. Channeling everything through one person prevents scattered disclosures and sets a natural, defensible pace.
- Sequence production in tranches. Deliver in agreed batches tied to the scope rather than in one rushed dump, so each tranche is accurate and reconciled.
- Request a confidentiality agreement before sensitive customer data moves. That is a reasonable protection, and arranging it is time well spent.
What you do with the time you create
Time is only valuable if you use it to build. The work that matters is the parallel reconstruction of your monthly position across the 36 month lookback, the same disciplined rebuild that turns the auditor's capacity count into a defensible consumption figure. While the auditor works from your infrastructure data, you work from your operations data, and you arrive at the reconciliation meeting with a number of your own.
A sequence that holds
| Phase | Auditor activity | Your activity |
|---|---|---|
| Notice and scope | Proposes timetable and data list | Agree scope in writing, set the contact, request confidentiality |
| First tranche | Reviews infrastructure data | Deliver in scope data, begin monthly reconstruction |
| Reconciliation | Presents draft capacity figures | Put your reconstructed monthly position beside theirs |
| Settlement | Microsoft sizes back fees and uplift | Fix the base, argue the uplift down on good faith evidence |
Where buying time crosses a line
There is a difference between using time and ignoring the auditor. Missing agreed deadlines without explanation, refusing reasonable requests that are properly scoped, or going silent all hand the auditor a reason to escalate and to let their high opening figure stand. Buying time means staying engaged, responsive, and visibly cooperative while you do the accuracy work. The posture is calm and constructive, never obstructive.
Why this protects the number
The opening figure is built to be high. Every week you convert into a more complete reconstruction is a week that pulls the final number toward reality. Back fees follow the reconstructed consumption, so accuracy there is permanent value. The uplift of 25 to 125 percent is negotiable, and the evidence you assemble in the time you create is what argues it down. Time, used well, is not a delay tactic. It is the defense.
What to do now
If the auditor's timetable already feels faster than your accuracy, that is the signal to bring independent help in early. Book a Strategy Call and we will map the scope, the sequence, and the reconstruction with you before you answer the next request.
