Post: Case Study: Thomas Reduces Invoice Processing From 45 Min to Under 1 Min

By Published On: March 25, 2026

Thomas at NSC spent 45 minutes on every vendor invoice—email to accounting system to approval queue to file. Make.com automation now handles the entire process in under one minute while Thomas focuses on work that actually requires his judgment.

What made Thomas’s invoice process so time-consuming?

Seven manual steps across four different systems with no handoffs between them. Every invoice required human attention at each stage—extract, cross-reference, enter, route, confirm, file. At 30+ invoices per month, that’s 22+ hours monthly on a single process.

Expert Take: Invoice processing is a perfect automation target because it’s high-volume, highly structured, and the failure modes are well-defined. When the data matches, the workflow runs. When it doesn’t, a human gets a specific alert with everything they need to resolve it. No ambiguity, no missed steps.

How did Make.com connect the existing systems?

OpsMesh™ mapped the data flow between email, the PO tracking spreadsheet, the accounting platform, and the approval routing tool. Make.com’s native connectors handled the integrations without any custom code. The scenario parses invoice data from the email body, validates it against the PO record, and routes it through the approval chain automatically.

What happens when there’s a discrepancy?

The workflow pauses, flags the specific mismatch (wrong amount, missing PO reference, duplicate invoice number), and routes a detailed alert to Thomas with the original invoice attached. He resolves the exception in minutes rather than discovering it during a manual review cycle days later.

What did Thomas do with the 22 hours per month he recovered?

Built a vendor performance tracking dashboard that NSC leadership had been requesting for two years. The data was always there—the bandwidth to compile and present it wasn’t. Automation created the capacity for the strategic work, not just the administrative work.

Frequently Asked Questions

  • What was the 45-minute process Thomas was running manually? Receiving a vendor invoice via email, extracting line items, cross-referencing against purchase orders, entering data into the accounting system, routing for approval, and filing the original email.
  • How does Make.com handle the same process? The workflow triggers on invoice receipt, parses key fields, validates against PO data, routes to the accounting system, sends an approval notification, and archives the original—all in under 60 seconds.
  • What happened to the time Thomas reclaimed? He moved from reactive invoice processing to proactive vendor relationship management and cash flow reporting that the team hadn’t had bandwidth for previously.
