Learn how to do invoice line item verification the “smart way”

A silly image of an older man resembling Einstein working at a laptop.

As they say, the devil is in the details. Invoice errors can be detected by reviewing each and every line item of hundreds of due invoices. However, manual line item verification not only requires time and labor, but it also diverts your workforce from more vital tasks. Through smart line item verification, you get the job done in minutes and save thousands of dollars back into your pocket.

Why Smart Line Item Verification Matters

A disciplined invoice validation process, focused on every line item, is the smart way to stop profit leakage during invoice processing.

Line-item verification uses structured item analysis to verify pricing, quantities, taxes, and duplicates before payment. This serves as an ongoing invoice audit and fraud prevention layer, enhancing the detection of errors across all items.

Manual checks are tedious. With invoice automation, verification software performs automated invoice validation at scale, embedding controls directly into accounts payable (AP) workflows. When exceptions arise, AP is alerted for fast reconciliation.

Common Causes of Duplicate Invoices

Here are the following common errors in invoice line items:

Manual Calculation Errors:

Manual keying and copy-pasting spreadsheets can cause mistakes in subtotals, taxes, and discounts during the invoice processing. Even small math errors can multiply across high-volume invoices, which can cause avoidable expense and AP rework.

Incorrect Applications in Pricing Taxes:

Misapplied tax rates, misread contract terms, and outdated price tables can impact line items and cause material overcharges on large orders.

Transposed Number:

Transposed numbers are digital reversals during manual entry. For example, the correct total is 1,200. However, it was manually keyed in as 2,100. Small errors like these are hard to detect when verifying hundreds of invoices monthly manually.

Misplaced Decimal Points:

Decimal shifts, like 34.75 being manually entered as 347.5, can impact quantity, unit price, tax, or freight. This results in significant overpayment when applied across hundreds of invoices.

Duplicate Invoices:

Duplicate invoices can be caused by a vendor sending an invoice with the same line items under a different invoice number to remind the client to pay. It can also be caused by the same invoice being entered twice by mistake or by synchronization issues across accounting systems.

Double Date Entry Errors:

In some cases, the same line items may appear twice in a single invoice, causing inflated payables.

Fortunately, there’s an invoice verification software that can detect all of these errors for you.
