## Content

**Intro:** Most published figures for the cost of processing an invoice do not say what they include. This calculator builds the number from your own labor, software, capture fees and the exception work that lands on buyers and receiving.

**Sections:**

#### How to use the calculator

**Body:** Start with yearly invoice volume and the FTE time that really goes into invoice processing. Add software and per-page capture fees, then estimate how many invoices need help from someone outside AP and how long that takes. The result is a fully loaded cost per invoice and an invoices-per-FTE figure that you can set against internal targets.

**Bullets:**

- Use time studies or workflow timestamps for the FTE share.
- Include ERP add-on and support costs in the software line.
- Leave the page fee at zero for flat or self-hosted capture.

#### The method

**Body:** Total cost is AP labor plus software and page fees plus exception work done outside AP. Cost per invoice is that total divided by annual invoices. The exception line is often the largest hidden cost because it sits in other departments' budgets. A twelve minute buyer interruption on one invoice in five is easy to overlook, yet over tens of thousands of invoices it can rival the AP payroll.

#### How to read the result

**Body:** Compare the cost per invoice before and after an automation project using the same definition. The chart shows how sensitive the figure is to exception rate: if the line is steep, fixing the cause of exceptions (price mismatches, missing receipts, unit-of-measure errors) will save more than buying a better extraction engine.

#### Common mistakes

**Body:** Do not count FTEs who mainly handle payments, vendor master changes or reconciliations. Do not count a licence twice if it is already inside the ERP line. And avoid comparing your figure to a headline benchmark without checking whether it includes approval time, storage and exception handling.

**Cta:** If you want the exception rate and minutes pulled directly from ERP and workflow data rather than estimated, Netray can help wire that up.

**Faq:**

#### What does it cost to process one invoice?

**Answer:** It varies by volume, PO coverage, automation level and what is counted. Treat any single benchmark with caution and build your own figure from labor, tools and exception work, as this calculator does.

#### Why include exception work outside AP?

**Answer:** Because the cost is real even though it is booked elsewhere. Buyers, receivers and requesters spend time resolving mismatches, and omitting it makes the process look cheaper than it is.

#### Should payment runs be included?

**Answer:** Usually not. Keep the scope to receiving, capturing, coding, matching, approving and posting the invoice, so that the figure reflects invoice processing only.

#### How do I count a part-time AP clerk?

**Answer:** Use the fraction of their paid time spent on invoice processing, based on a short time study. Entering 0.5 FTE for half a person is better than rounding to one.
