Case Study: Automating $1M in Transactions with 99.5% Accuracy

Processing transactions manually is a slow-motion car crash for most scaling businesses. As volume grows, so does the rate of human error. For “LogiTrack” (a pseudonym for a mid-sized freight forwarding client), that crash was happening every month.

They were managing over $1M in monthly billable transactions across 400+ vendors and 1,200+ clients. Their accounts payable and receivable teams were drowning in PDFs, CSV exports, and manual data entry. By the time we stepped in, their error rate was hovering around 6%, leading to over $15,000 in monthly losses due to overpayments and missed billing opportunities.

The challenge wasn’t just the volume; it was the variety. Invoices came in different formats, languages, and currencies. A simple rule-based automation wouldn’t cut it. They needed an agentic system that could “understand” the context of each transaction.

The Problem: The “Human Bottleneck”

LogiTrack’s workflow looked like this:

1. Receive an invoice via email.
2. Download the PDF and manually check it against a purchase order (PO) in their custom ERP.
3. Identify if the line items matched the agreed-upon rates.
4. Manually enter the data into their payment gateway.
5. Send a confirmation email to the vendor.

The team was spending 140+ human hours per week just on this data entry cycle. Worse, because they were rushed, they often missed “hidden” fees or failed to catch duplicate invoices.

The Solution: Building an Agentic Reconciliation Layer

We replaced the manual entry with an autonomous agentic workflow built using Make.com for orchestration and Relevance AI for the “thinking” part of the process.

The new workflow followed a structured, five-stage autonomous process:

Stage 1: Intelligent Intake

Instead of a human inbox, all invoices were routed to a dedicated “Intake Agent.” This agent didn’t just OCR the text; it used a vision-capable LLM to understand the layout of the document. It could distinguish between a “Balance Due” and a “Total Amount” (which are often different on freight invoices) and could identify handwritten notes on scanned documents.

Stage 2: Cross-Reference and Validation

Once the data was extracted, the agent queried the internal ERP database. It checked:

• Does this PO exist?
• Is the vendor’s bank info the same as what we have on file? (A crucial check for fraud prevention).
• Are the line items within a 2% variance of the quoted price?

Stage 3: The “Exception” Filter

This is where the agentic approach shines. If a transaction was 100% matched, it proceeded to Stage 4. If there was a discrepancy—say, a $50 “fuel surcharge” that wasn’t in the original quote—the agent didn’t just stop. It searched the company’s internal Slack history for any mention of that surcharge. If it found a message from a manager saying “Approved the fuel surcharge for Vendor X,” the agent linked that message to the transaction and moved it forward.

Only if it couldn’t find a justification did it flag the invoice for a human to review.

Stage 4: Execution

Approved transactions were then pushed via API to their payment processor and their accounting software (QuickBooks Online). The agent handled the multi-currency conversion at the real-time spot rate, ensuring the books were balanced down to the cent.

Stage 5: Feedback and Closure

Finally, the agent drafted and sent a personalized email to the vendor, including a breakdown of what was paid and the internal tracking number.

The Results: Scaling Without Headcount

After a 60-day rollout, the results were transformative:

• Volume Handled: $1.14M in transactions processed in the first full month.
• Accuracy Rate: 99.5% (down from a ~94% human accuracy rate).
• Time Savings: Total human intervention dropped from 140 hours/week to just 12 hours/week (primarily for reviewing complex exceptions).
• Hard Cost Savings: Caught $8,400 in duplicate invoices and $4,200 in overcharges that would have previously gone unnoticed.

The most significant win, however, wasn’t financial. It was the shift in team morale. The finance team stopped being “data entry clerks” and started being “financial analysts.” They were no longer stressed about missing a decimal point; they were focused on optimizing vendor terms and improving cash flow strategies.

Key Takeaway for Business Owners

You don’t need a $100k enterprise software suite to achieve this level of automation. By combining existing no-code tools with agentic AI, even a mid-sized business can build “bespoke” automation that understands their unique business rules.

The goal isn’t to remove the human entirely—it’s to ensure the human is only called upon when their judgment is actually required.
