Dental office invoice approval should establish that the practice owes the stated supplier the exact amount proposed for payment. Match the authorized order, evidence of receipt or completed service, and invoice. Resolve differences, check earlier payments and credits, and verify payment details before an authorized person releases funds.
The purchasing approval process establishes permission to order. An approved purchase does not prove that the invoice is accurate, the full shipment arrived, or the bill remains unpaid.
The FTC recommends clear purchase and invoice approval procedures and close inspection of bills. Turn that principle into a repeatable review of each payable item. FTC guidance on checking business invoices
Give each invoice one controlled record
Use one approved intake route and assign a record reference. Preserve the invoice as received, including its date, supplier identity, invoice number, account number, amount, terms, and receiving date. Connect it to the correct practice entity and location.
Check for prior entries before creating a new payable. Search the supplier, invoice number, amount, order reference, and service period. A supplier might resend a bill with “copy” added or omit punctuation from its invoice number. Exact text matching alone can miss that duplication.
Look in the payment history too. A bill for an order paid by card at checkout may document an existing charge. It should not automatically generate a second payment. Likewise, a supplier statement lists account activity; investigate its component invoices instead of entering the statement total as another bill.
Choose a status that describes the actual stage: awaiting evidence, under review, disputed, approved for a specified amount, scheduled for payment, or paid with a transaction reference. “Entered” and “approved” should remain distinct.
Match the obligation, the receipt, and the bill
Review line items before the grand total. Give each difference an owner and supporting record.
| Match | Evidence to inspect | Exception to investigate |
|---|---|---|
| Authorized order to invoice | Final quote or order, approved quantities, prices, freight, and terms | Added item, changed unit price, or unapproved fee |
| Receipt to invoice | Receiving record, accepted quantities, returns, and backorders | Full quantity billed despite a partial delivery |
| Service to invoice | Work order, covered dates, and authorized acceptance | Maintenance period overlaps an earlier bill |
| Credits to balance | Issued credit memo and the invoice it affects | Return accepted but credit not reflected |
| Payment history to amount due | Deposits, card charges, checks, and transfers already recorded | An advance or prior payment remains unapplied |
Check purchase units carefully. Ten boxes, ten cases, and ten individual items may represent different quantities. Ask the receiver to confirm what arrived against the product and packaging details; do not solve the discrepancy by assuming the cheaper interpretation.
For equipment or repairs, delivery may precede installation or acceptance. Identify the contractual milestone that makes a payment due and obtain the appropriate sign-off. The manager should coordinate acceptance with the authorized technical or clinical reviewer when needed.
Recalculate extensions, discounts, shipping, and quoted taxes. Route a tax-treatment question to the accountant or supplier for resolution. A familiar total is not evidence that every charge is correct.
Keep preparation and release independently reviewable
Name the preparer, receipt confirmer, approver, and payment releaser. In a small practice, one employee may hold several roles, but an owner or authorized independent reviewer should inspect the original evidence before release.
The ADA recommends separating financial functions to reduce unchecked control over the money trail. Apply that principle to this invoice: the second reviewer needs the source documents and exception resolution, not only a list of proposed payments. ADA guidance on financial responsibilities
Define who approves unusual items and who acts during absences. Make the approval specific to the supplier, invoice, net amount, and payment method. If any of those changes materially, return the changed item for review under the office's policy.
Use the broader embezzlement-prevention controls for financial access and oversight. This payment check should remain focused enough that a reviewer can actually perform it.
Resolve a partial shipment without paying twice
Consider this hypothetical supply order. The office approved twelve cartons at $48 each. The supplier's invoice includes $24 freight and $40.32 tax, for a total of $640.32. For this example only, the quoted tax equals 7% of the product amount and excludes freight.
Only ten cartons arrive. The supplier confirms cancellation of the two missing cartons and issues a credit that reverses their price and associated tax. There is no remaining backorder in this example.
| Reconciliation | Amount |
|---|---|
| Original products: 12 × $48 | $576.00 |
| Original quoted tax | $40.32 |
| Freight | $24.00 |
| Original invoice | $640.32 |
| Credit for two canceled cartons | −$96.00 |
| Tax reversed on those cartons | −$6.72 |
| Approved remaining payable | $537.60 |
Check the result independently: ten cartons cost $480; their hypothetical tax is $33.60. Adding $24 freight gives $537.60. The credit totals $102.72, and $640.32 − $102.72 produces the same remaining amount.
The approver should see the original authorization, receipt for ten cartons, cancellation confirmation, credit memo, and balance calculation. An employee's note saying “supplier will credit us” is not the same as the issued credit assumed here.
If the supplier also sends a revised $537.60 invoice, identify whether it replaces the original. Do not leave both versions available for payment. Preserve the history and the replacement relationship in the accounting system.
For an actual unresolved shortage, follow the supplier agreement and obtain instructions about disputed and undisputed amounts. Do not silently short-pay, rewrite the due date, or declare an obligation canceled because goods are missing.
Verify changed payment details outside the request
A correctly billed purchase can still be paid to the wrong destination. Treat new banking instructions, a changed remittance address, or a different payment method as a separate verification task.
The FBI advises verifying payment requests and account changes. Use an established contact channel independent of the message requesting the change; a phone number supplied in that same message cannot independently establish its legitimacy. FBI business email compromise guidance
Record who verified the change, when, through which known channel, and who approved the vendor-record update. Keep sensitive banking details in the approved accounting or banking system. If verification fails, escalate before release, even when the underlying invoice is otherwise ready.
Close approval with an exact payment instruction
A useful approval record reads: “Invoice [reference], less credit [reference], approved for [net amount] by [person] on [date], using verified vendor details. Remaining exception: [none or specific item].”
The releaser then checks that the payment screen agrees with that authorization. Record the transaction reference and prevent the same invoice from re-entering the next payment run.
After payment, the bank reconciliation workflow verifies the cash movement. Retain the invoice-to-payment connection so another reviewer can trace what was ordered, received, credited, approved, and paid without reconstructing the story from memory.
