Back Office for 3PL Providers
Client billing, inventory reconciliation, chargeback management and carrier invoice audit — run by a dedicated team inside your own WMS.
3PL back office outsourcing
Margin lives in the administration.
A 3PL runs on thin, per-transaction margin across many clients — each with a different rate card, storage terms, billing format and compliance requirement. Every uninvoiced handling charge, every absorbed retailer chargeback and every unreconciled inventory variance comes straight off the bottom line.
Infinity IPS runs that administration for 3PL providers — as a dedicated team working inside your existing WMS and TMS, so your clients see no change. We have supported logistics back office operations since 1998.
Why 3PLs work with us
Built for multi-client complexity.
The hard part of 3PL administration is that no two clients are billed the same way.
- Per-client rate cards, storage terms and billing formats
- Storage, handling and accessorial charge calculation
- Retailer chargeback logging, dispute and root-cause reporting
- Cycle count and inventory variance reconciliation
- EDI 940, 945, 856, 810 and 214 processing
- OS&D claims and returns disposition
Billing & revenue protection
Everything billable, actually billed.
Storage that rolled into a new period. A pallet reconfiguration nobody logged. A chargeback raised in error and quietly absorbed. We catch each of these through our receivable management and accounts payable services.
Client billing
Per-client rate cards applied without leakage.
- Storage, handling and pick/pack charge calculation
- Per-client rate card and contract term application
- Accessorial and value-added service billing
- Client-specific invoice format compliance
- Client and account-level profitability reporting
Chargeback management
Disputed where wrong, fixed where recurring.
- Retailer chargeback logging and categorisation
- Traced against shipment and compliance requirement
- Dispute filing with supporting evidence
- Root-cause reporting on recurring deductions
Carrier invoice audit
Your own freight spend, checked line by line.
- Contract rate verification across TL, LTL and parcel
- Accessorial validation — detention, lumper, redelivery
- Duplicate invoice detection
- Dispute handling and credit tracking
Inventory & fulfilment
The reconciliation nobody has time for.
Cycle counts, variance investigation, OS&D claims and returns disposition are the tasks that slip when volume rises — and the ones that cost most when they slip. Part of our logistics back office services.

Variances investigated, not just recorded.

Common questions
3PL back office, answered.
What does a 3PL back office cover?
Client billing and storage charge calculation, carrier invoice audit, inventory and cycle count reconciliation, retailer chargeback management, OS&D claims, returns processing, and order and shipment documentation across your WMS and OMS.
Can you handle billing across multiple clients?
Yes. Each client has its own rate card, storage and handling terms, and billing format. We calculate and issue invoices per client against their own agreement, and can report profitability at client, account or SKU level.
Do you manage retailer chargebacks?
Yes. We log chargebacks as they arrive, trace each against the shipment and compliance requirement, dispute those raised in error, and report recurring causes so the underlying issue can be fixed rather than repeatedly absorbed.
What EDI transactions do you process?
EDI 940 warehouse shipping orders, 945 shipping advice, 856 advance ship notices, 810 invoices and 214 status messages — alongside portal and spreadsheet formats from clients who do not trade EDI.
Do you handle OS&D claims and returns?
Yes. Over, short and damaged claims are documented against the POD and delivery record, filed with the carrier and tracked to settlement. Returns are processed against the original order with disposition recorded in your WMS.
Do you work inside our existing WMS?
Yes. Our teams work daily in major WMS, TMS and ERP platforms including Blue Yonder, MercuryGate, Descartes, SAP, Oracle, NetSuite and CargoWise. There is no migration and your clients see no change.
