Start with your 3PL invoice. Add your rate card and operations export when available to increase audit coverage. BillDrift maps each supplied CSV or XLSX export to its audit model first. Original files are not stored.

Upload the CSV or XLSX invoice export you already have. BillDrift maps common 3PL column names and spreadsheet formats automatically.

Want deeper checks? Add optional evidence
Your invoice alone can be checked for eligible invoice-level issues. Add a rate card to compare billed rates with your commercial terms. Add operations data to support reference and quantity checks.
Operations data · optional
Use one operations export in the normal workflow. Switch to multiple exports only when your 3PL separates shipment, receiving, return or storage evidence.
Need help with your files?
Smart Import recognizes common 3PL headers, CSV delimiters, decimal formats and date formats. XLSX workbooks may contain titles, blank rows and multiple worksheets. If more than one table is plausible, BillDrift asks you to choose instead of silently guessing.
Templates are optional. You do not need to rename provider columns to BillDrift's canonical schema before trying your file.
Optional canonical BillDrift schema reference
Rate card: service_code, service_name, billing_basis, unit_rate. tolerance_pct, effective_from, effective_to, tier_mode, tier_from_qty, tier_to_qty and minimum_charge are optional. A minimum_charge sets the minimum contract amount for each invoice line. Volume and graduated tier modes are supported.
3PL invoice: invoice_id, line_id, service_code, reference_id, quantity, unit_rate, amount, date.
Operations: reference_id, units, shipped_at. weight_kg, pallets, storage_units, received_units and returned_units are optional. storage_units is the billable storage quantity. weight_kg supports weight-based rates.
BillDrift's canonical templates use YYYY-MM-DD. Smart Import can normalize supported alternative date formats before the existing audit parser runs.
Start with your invoice
The sample uses synthetic data and does not use your free preview.The 3PL invoice is required. Rate card and operations files are optional evidence that unlock additional checks.
Turn a complicated invoice into a focused review queue.
BillDrift focuses on discrepancies that can be tested from structured data. A finding tells you what deserves review; it does not replace commercial judgment.
Possible duplicate charges
Flags repeated invoice lines and references so you can verify whether the same billable event was charged more than once.
Rate drift
Compares billed unit rates with the rate-card values you provide and surfaces differences for review.
Invoice arithmetic
Recalculates straightforward quantity × rate relationships and flags line amounts that do not reproduce.
Unknown fee codes
Shows invoice services that cannot be matched to the supplied rate card instead of silently assuming they are valid or invalid.
Unsupported references
Identifies billed order or activity references that cannot be found in the operational data you provide.
Quantity mismatches
Compares billed quantities with matched operational quantities where the available data supports a deterministic check.
Evidence your operations team can verify before raising a query.

What is a 3PL invoice audit?
A 3PL invoice audit compares what your fulfillment provider billed with the commercial rates you agreed and, where possible, the operational activity recorded in your own systems. The goal is to identify specific discrepancies that deserve review rather than judging the invoice only by its grand total.
What files do I need to use BillDrift?
You only need a detailed 3PL invoice to start. A rate card is optional and unlocks contract-rate, effective-date and unknown-service checks. Add an operations export as well to unlock supported reference and quantity checks. BillDrift shows which checks were performed and which were skipped.
What does BillDrift check?
BillDrift checks deterministic relationships supported by the files you provide, including possible duplicate lines, rate differences, invoice arithmetic, unknown fee codes, unsupported operational references and quantity mismatches.
Is the free 3PL invoice audit really free?
Yes. The free preview checks up to 100 invoice rows and shows a summary plus the first five findings. You do not need an account or payment card for the free preview.
Does BillDrift store my raw CSV files?
BillDrift processes the uploaded data to perform the reconciliation, but the raw uploaded files are not stored as part of your saved audit history.
Does BillDrift decide whether my 3PL legally overcharged me?
No. BillDrift produces reconciliation evidence and structured findings. Contract interpretation, commercial context, provider communication and any legal conclusion remain human decisions.
