A rebate true-up is the period-end or year-end reconciliation that adjusts booked rebate accruals to the actual earned amount confirmed against the trading agreement. In the Contract Performance Management stack the rebate true-up is a small confirmed delta at period end rather than a year-end surprise, because the accrual reprices continuously against the running earn-rate as posted purchases land.
How it works
A rebate true-up closes the gap between the in-year accrual and the final earned rebate. Through the year the buy-side team books an accrual against the running earn-rate for each open program window. At period end, actual qualifying volume is confirmed against the trading agreement, the supplier issues the settlement or credit note, and the true-up entry moves the accrued balance to the confirmed amount.
A working system runs the true-up as a continuous calculation, not a year-end fire drill. Each posted purchase reprices the accrual against the machine-readable rule the moment the volume clears the next tier or trigger, and the supplier statement reconciles line by line against the same engine. When the period closes the true-up entry is a small delta the finance team already forecasted, not a step change in delivered margin discovered at close.
Why it matters
A rebate true-up is where the buy-side finance team either confirms the year or absorbs a step change in delivered margin at close. WorldCC records 19% average contract value leakage against a 3-7% best-in-class band; on tiered rebate portfolios the year-end true-up is the single point where uncaught tier crossings, missed thresholds, and stale accruals all surface at once. Aberdeen puts 65% of admin time back on the calendar when the true-up runs against structured data instead of a reconciliation spreadsheet.
How Vendortell handles it
Vendortell handles rebate true-ups as one workflow inside its Contract Performance Management platform. Each trading agreement is extracted during onboarding, the accrual reprices against the running earn-rate as posted purchases land, and the true-up entry becomes a small confirmed delta at period end. See the rebate accounting page for the wider general-ledger mechanic, or the rebate reconciliation page for the line-by-line matching workflow that feeds the true-up. Onboarding runs in 30 days.
FAQ
How is a true-up different from a rebate accrual?
The accrual is the in-year finance entry booked against the running earn-rate for an open program window. The true-up is the period-end or year-end adjustment that moves the accrued balance to the actual earned rebate confirmed against the trading agreement and supplier statement.
When does a rebate true-up typically fire?
At the close of each program measurement window: monthly, quarterly, or annually depending on the trading agreement. Annual programs still need in-year visibility on the projected true-up so the finance team can forecast the delivered margin position ahead of close.
What triggers a large negative true-up at year end?
Tier crossings that were priced but never posted, mix modifiers assumed against the wrong SKU catalogue, and standing accruals that were never reconciled against the supplier statement. Portfolio-level accruals hide the underlying drift until close.
How does the true-up reconcile to the supplier settlement?
Line by line against the trading-agreement clause and the posted-purchase feed. Each accrual is matched to the specific program window it belongs to, so the supplier statement and the buy-side ledger clear against the same source of financial truth.
