The Grocery AP Automation Benchmark Report: Summer 2026 Edition
by Mike Waldron
Why this report exists
When independent and regional grocers operate on margins of just 1-3%, even a fraction of a percentage can be the difference between a profitable and an unprofitable quarter. So if a UNFI invoice arrives with 15 incorrect line items or a DSD vendor slowly increases prices for three months, it can take a major toll on the bottom line.
While most grocery operators are aware of the problem, far fewer have the data to quantify its impact. But walking into a vendor conversation with claims of overbilling, owed credits, or suspicious patterns won’t get you very far without the data to back them up. Each quarter, Ottimate processes thousands of invoices for our grocery customers. We’ve compiled that data into a snapshot to help grocers quantify what’s really happening. It provides benchmarks based on real grocery operations, rather than industry estimates or survey responses. The first edition of the Grocery AP Automation Benchmark Report covers overcharges, fraud exposure, discrepancy rates, payment errors, invoice lifecycle time, and AP labor savings. Twice a year, we’ll track how these numbers evolve and what’s driving the changes so grocers have an ongoing benchmark for how they stack up and where there are opportunities to improve performance.

The overcharges nobody sees
Here’s the thing about vendor overcharges: they don’t show up as a line item called “billing error.” They hide in price creep, in catch weight variances, in DSD slips that nobody had time to reconcile. For a multi-store operator without automated overcharge detection, $37,000 per location is quietly leaving every year across all locations.
Where a fake invoice blends in
Three out of four grocers had an invoice flagged for fraud in the first half of 2026, up from 55 percent who saw fraud across all of 2025. Grocery is a target for a reason, since high invoice volume, thin margins, and hundreds of vendors on tight delivery windows give a slightly altered remit address plenty of places to blend in.
Catching it beats chasing it
Once a payment goes out, recovering it means chasing a credit memo from a vendor with every incentive to be slow. The grocers who catch errors before disbursement aren’t just saving money. They’re avoiding a process that’s slow, frustrating, and often unsuccessful.
More invoices, same staff
Labor savings increased from $264K to a projected $280K, a modest jump on paper and a meaningful one in practice. It means grocers have absorbed higher invoice volumes and higher wage costs without adding a person to the AP team, and the savings grow on their own once the workflows are built, because every new invoice runs through an existing process.
AP labor savings
Ottimate codes 93.3 percent of line items to the correct GL automatically, saving customers an average of 106 hours per month. In 2026, Ottimate is coding 94.9 percent of grocery line items to the correct GL without anyone touching them. The typical grocery account is getting back 182 hours of GL coding labor per month. For a one- or two-person AP operation, which describes most independent grocers, 182 hours is a different job description. That’s the AP clerk who’s no longer the human scanner, manually keying data that’s already digital. It’s the controller who closes the month without a week of cleanup first.
About this report
The Grocery AP Automation Quarterly Trends Report is published by Ottimate using aggregated, anonymized data from our grocery customer base. All benchmarks reflect real invoice processing data across independent and regional grocery operators. This is the first edition; future editions will track trends and flag what’s driving the changes.
