Turn every pallet-day into an audit-defensible invoice
3PL Warehouse Billing turns receipts, put-aways, and picks into an immutable movement log, frozen nightly snapshots, and rate-card-driven billing runs — so every invoice line traces straight back to the dated warehouse event that created it.
The problem
3PL warehouses store inventory for dozens of clients under one roof, but billing is reconstructed from spreadsheets exported out of the WMS. Charges lag the warehouse floor, disputes drag on for hours while staff trace a line back to the pallet that generated it, and one client's stock can end up billed against another client's account.
The solution
Every stock movement is captured in an immutable, append-only log the moment it happens. Nightly cron jobs freeze pallet-day snapshots per client and location, and billing runs turn those frozen facts into rate-card-priced invoice lines — each one clickable straight back to the exact movement or snapshot that produced it.
Everything a 3PL billing desk needs
Every capability below is implemented in the module.
Immutable Owner Segregation
Every unit of stock carries a permanent client/owner field, so one client's inventory can never be viewed, moved, or billed against another client's account.
Append-Only Movement Log
Receipts, put-aways, picks, and adjustments write to a movement log that cannot be edited or deleted once logged — the tamper-proof backbone every invoice line traces back to.
Nightly Pallet-Day Snapshots
A scheduled job freezes pallet-day occupancy by client and location every night, so the storage basis behind an invoice never shifts after the fact.
Per-Client Rate Cards
Configure storage, handling-in, handling-out, and value-added pricing per client, complete with a minimum charge per service line.
Automated Billing Runs
Billing runs calculate storage and handling charges straight from frozen snapshots and logged movements, applying a monthly-minimum fallback automatically.
Draft Sale Order Generation
Confirmed billing runs generate a standard Odoo sale order quotation, so charges flow through the approval and invoicing workflow your finance team already knows.
Storage Statement PDF
Every storage statement renders each billed line beside the frozen snapshot and dated movement it came from — a self-evident, printable audit trail for disputes.
Client Self-Service Portal
Clients log in to see current pallet-on-hand inventory by location, review billing statements, and drill into activity — without emailing your team for status.
Revenue & Margin Analytics
A pivot table breaks down revenue by client and service type, giving operators a real-time view of margin per account.
How it works
Configure rate cards
Set up per-client rate cards, billing profiles, and monthly minimums for storage, handling, and value-added services.
Activity logs automatically
Every receipt, put-away, and pick from stock operations writes an immutable movement record tied to the owning client.
Snapshots freeze nightly
A nightly cron job snapshots pallet-days per client and location, creating a locked storage basis for billing.
Run billing, confirm, invoice
Calculate a billing run against the frozen snapshots and movements, confirm it into a sale order, and the client sees the statement in their portal.
Frequently asked

No. It builds directly on Odoo's existing stock module and the owner field already used for consignment stock, so there is no separate warehouse system to run alongside Odoo.
