Reconcile SLA Service Credits Without Approving Refunds

Freeze the contract formula and measurement window

Before calculating anything, locate the service-level clause that defines the credit, the measurement window, the excluded events, and the maximum credit. Record the contract version and the effective dates. If the clause is ambiguous, stop and route the question to the contract owner rather than choosing the reading that produces a credit.

The outsourced role can transcribe the formula and apply it to supplied data. It cannot decide whether an outage counts as excused, whether a force-majeure notice is valid, or whether the company should waive a credit. Those decisions belong to the owner named in the contract.

Collect outage and ticket evidence

Gather the incident records, monitoring timestamps, customer reports, and resolution notes that the company treats as authoritative. Record the start and end time in the source time zone, the affected service, and the severity. Do not merge two incidents because they look related unless the contract or the owner defines them as one event.

Attach the evidence to each incident and note gaps. A monitoring gap is not proof that service was available, and a customer report is not proof of duration. The worksheet should show which evidence supports each minute counted and which periods remain unknown.

Calculate credits with a reproducible worksheet

Build the worksheet in the approved tool with one row per incident and one column per input. Show the formula, the measurement window, the excluded periods, the rounding rule, and the resulting credit. Keep the source reference for every input so a reviewer can trace the number back to the contract and the incident.

Run a second calculation independently where the amount is material. Compare the two results and document any difference.

Do not adjust the worksheet to match an expected invoice; investigate the difference. A formula that cannot be reproduced by another reviewer is not ready to send.

Reconcile against billing and prior credits

Compare the calculated credit with the billing system, prior credit memos, and any manual adjustments. Record the invoice, the credit reference, and the period. A credit that was already applied should not be counted twice, and a credit that was promised but not posted should remain open.

If the billing system and the worksheet disagree, preserve both values and identify the source of the difference. Common causes include a different measurement window, a missed exclusion, or a manual adjustment. Route the discrepancy to the owner with the evidence rather than correcting the billing record directly.

Stop on formula ambiguity or missing evidence

Stop when the contract version is unknown, the measurement window is disputed, an exclusion is unclear, the incident evidence is incomplete, or the calculated amount exceeds the authority of the lane. Record the reason, the missing input, the owner, and the safe interim state.

A stop is especially important when the customer has already been told a credit will be issued. The coordinator should not confirm, deny, or quantify the credit to the customer until the owner approves. Keep the customer communication separate from the internal calculation.

Verify posting and customer confirmation

After the owner approves, verify that the credit reaches the billing system with the correct amount, period, and customer. Record the posting reference and the effective date. If the customer must be notified, use approved language and record the message and recipient.

Close by reconciling the contract, the incident evidence, the worksheet, the owner approval, the posted credit, and the customer record. Report unposted or partially posted credits separately. The measure of the lane is not the number of calculations completed but the number of credits that reached the right account with the right evidence.
