Event supplier invoice approval checklist and editable review sheet
An invoice can look routine even when the event plan has changed. The venue may have added a room, the AV supplier may have delivered fewer microphones, or a deposit may already have been paid. Before releasing the invoice for payment, match what was agreed, what was accepted and what is actually billed. This review sheet records exceptions and keeps approval separate from proof that money was sent.

Use one copy per invoice. Record the event edition, supplier, contract or purchase-order reference, invoice number, reviewer, evidence, exception owner and approval decision. The sheet is an organizer's review aid, not an accounting system or a substitute for local tax and authorization requirements.
Match the agreement, delivery and invoice
Start with the signed scope and approved changes. Identify the exact milestone being billed: for example, an equipment deposit, completed venue hire or post-event teardown. Ask the operational owner whether that milestone was delivered and accepted, and link the delivery note or sign-off. An invoice arriving before an agreed milestone is evidence to investigate, not automatic proof that the service is complete. Procurement workflows commonly reconcile an order, a receipt or acceptance and an invoice; adapt that principle to the event's actual documents.[2][1]
| Record | Question before approval |
|---|---|
| Agreement and changes | Is this supplier, scope, milestone, price, currency and payment schedule approved? |
| Delivery or acceptance | Which owner confirms the goods or service received, and what exception remains? |
| Invoice | Do the line items, quantities, tax lines, due date and total match the agreed and accepted work? |
| Prior money | Are deposits, part payments and credit notes reflected once, not twice? |
If the invoice covers several milestones, check each line independently. Where a service was partly accepted, record the disputed line and request a corrected invoice, credit or authorized exception rather than silently changing the amount.
Calculate what remains payable
Check unit prices, quantities, additions, discounts, tax treatment and currency with qualified finance staff. For a simple example, if an agreed invoice total is 1,000 in the contract currency, a 200 deposit has already been paid and a 100 credit is due, the remaining balance is 700. First verify whether the supplier already netted the deposit or credit on the invoice; subtracting either twice would create a false shortfall. Local tax invoice details and who may approve payment depend on your organization and jurisdiction.
Search the payment record for the invoice number, amount and supplier before approving it. Duplicate numbers, changed beneficiary details or an unexplained new bank account require a hold. A due date affects scheduling, but urgency is not a reason to bypass checks.[1][3]
Verify payment changes through a trusted channel
Business email compromise can involve a convincing request to change supplier payment details. Compare the invoice with the independently maintained vendor record. If bank instructions change, contact a known supplier representative using a previously verified number or channel, not a number supplied in the change request. Record who checked, when and what was confirmed. The FBI's IC3 specifically recommends independent verification of changes to payment procedures.[3]
Approve, hold or reject; then reconcile payment separately
An authorized approver records one decision: approve the supported amount, hold for a named clarification owner, or reject a duplicate or incorrect invoice. Include the amount, currency, date, evidence link and next action. Keep the outstanding exception visible in the supplier delivery and event budget records so a later reviewer knows why the invoice was held.[2]
Approval means the invoice may proceed under your policy; it does not mean the transfer settled. After the payment owner acts, record the bank or platform reference, date, amount and reconciliation status. This distinction prevents a marked 'approved' invoice from being mistaken for a paid one.
