We hunt down third party logistics overcharges using external, programmatic API data pipelines that read 100% of your warehouse transactions. No manual spreadsheets, no sampling, and no disruption to your NetSuite or QuickBooks Online ledger.
What we handle
The friction
The traditional 3PL audit is a sampling exercise. A team of analysts pulls a handful of invoices, eyeballs the totals against a rate card, and signs off. That model is built to fail, because the overcharges that drain real margin are not large and obvious. They are small, systematic, and buried inside the 90% of data that is billed correctly. Human eyes reviewing a sample never see them. Code reading every line does.
A TikTok Shop order billed at the wrong shipping zone adds a few cents per package. Across hundreds of thousands of packages, it compounds into five figures a month. Manual review of a 30 invoice sample will never catch a fractional zone misclassification.
When a label is regenerated or an order is split, some warehouse systems emit a second tracking event and the 3PL bills both. A spreadsheet reconciliation that matches invoice totals to a statement treats the duplicate as legitimate volume.
A pick charge applied to a cancelled line, a handling fee on a refunded unit, a master box counted as loose units. Each error is too small to notice and too systematic to ignore. We recalculate every line against the contract, so the fraction is exposed at scale.
Most 3PL invoices arrive as a blended aggregate. One channel overcharged by 10% disappears into the other 90% that is billed correctly. Without programmatic channel level segmentation, the leak is mathematically invisible.
The infrastructure
Our architecture sits outside your accounting system. We build read only API connections to your sales channels and your warehouse management platform, pull both datasets into an isolated audit hub, recalculate every charge against your contract, and output a clean exception report. Your general ledger is never written to. Your month end close is never interrupted.
Order, shipment, and status data from Shopify, Amazon SP-API, Walmart, and TikTok Shop is pulled through read only connections.
Billable event data from Deposco API payloads and ShipHero is ingested in parallel, down to the individual pick, pack, and storage line.
Both datasets meet inside an external pipeline that recalculates 100% of transactions against your contracted rate logic. No sampling. No spreadsheets.
Confirmed discrepancies are delivered as a documented report. Any recovery is recorded as a segregated journal entry your team controls, so the main ledger stays pristine.
Boolean logic in plain terms: IF a billed charge does not match the contracted rate for that exact channel, SKU, and service, THEN it is flagged, quantified, and packaged with evidence. Nothing is written back to your ERP without your sign off.
How it works
We provision read only credentials to your sales channels and WMS. No write permissions, no ledger access, no risk to your operational data.
We encode your 3PL master service agreement, rate card, and accessorial schedule into the audit engine as the source of truth for every recalculation.
Every billable event in the audited period is recalculated line by line and segmented by channel. Discrepancies are isolated, quantified, and evidenced.
You receive a dispute ready exception report with dollar amounts and supporting data. Optional continuous monitoring flags new leaks every billing cycle.
Why programmatic wins
| Dimension | Traditional Manual Sample Audits | Acgile Programmatic Audits |
|---|---|---|
| Coverage | A sample of 20 to 50 invoices | 100% of warehouse transactions in the period |
| Method | Human eyes against a rate card in spreadsheets | External API data pipelines recalculating every line |
| Channel visibility | Blended aggregate totals | Segmented by Shopify, Amazon, Walmart, and TikTok Shop |
| Micro billing leaks | Missed below the sampling threshold | Detected to the penny at scale |
| Ledger impact | Manual journal edits and reclasses | Zero writes to NetSuite or QuickBooks Online |
| Turnaround | Weeks of analyst man hours | Automated pipeline, repeatable every cycle |
| Evidence | Spot notes and screenshots | Line level documentation for every dispute |
Capabilities matrix
| Targeted anomaly | How Acgile catches it |
|---|---|
| Zone miscalculation | Packages billed at an incorrect shipping zone, most common on high volume TikTok Shop and Amazon flows. |
| Ghost tracking fees | Duplicate tracking events from regenerated labels or split shipments billed as separate fulfillments. |
| Status integrity gaps | Cancelled and refunded orders billed as fulfilled, caught by cross referencing your OMS. |
| Over pick and handling | Pick and handling charges on lines that were never shipped, recalculated against the contract. |
| Storage overstatement | Storage and long term storage fees billed on incorrect cubic volume or stale inventory counts. |
| Accessorial creep | Unauthorized surcharges, minimums, and handling fees that do not appear in your signed rate schedule. |
| DIM weight inflation | Dimensional weight billed above the actual carton dimensions in the WMS payload. |
