Review and approve event bills

Approve the vendor final bill for the conference and send it to Priya in procurement and to Mark, the finance director, for e‑signature in that order, with payment scheduled Friday—first verify each line matches the vendor contract, that tax codes are applied, and that the event code is on every expense line.

Before I approve this event bill, make it easy to sign off: surface any line items that exceed contracted amounts, group charges under venue, catering and AV with subtotals, mark disputed items with a red comment and add a one‑line reconciliation to the contract per group so Priya and Mark can confirm quickly.

The conference vendor sent the final invoice showing a 2,400 AV overcharge I didn't expect. I worry approving will overrun budget and reversing will upset the vendor before reconciliation. I cannot tell if the charge came from agreed extras or an error. Do I hold payment, query the vendor and alert Priya and Mark, or approve conditional payment while we investigate? Which minimizes vendor friction and risk to cashflow?

After events we often pay final bills and then spend days chasing vendors for line‑by‑line backup because we approved based on totals. This costs us credibility with procurement and creates reclassifications. Should we require line‑item backup before payment, implement a pre‑payment checklist, or set a one‑week hold period for review? Recommend the practical habit to stop these repeat follow‑ups and how to enforce it with vendors and procurement.
