A multi-warehouse 3PL operator replaced fragmented WMS and billing tools with Odoo — inbound, outbound, billing and client portals unified on one stack.
Reduction in billing disputes
Faster client onboarding
Improvement in pick accuracy
Reduction in support tickets
01 / Background
A regional 3PL operating multiple distribution centres across Europe and the Middle East, serving e-commerce, retail and industrial clients. Each warehouse ran a different WMS, billing happened in spreadsheets, and clients had no real-time view of their inventory or orders.
02 / Challenges
Each DC ran a different warehouse system, making consolidated reporting and process standardization impossible.
Storage, handling and value-added service charges were calculated in spreadsheets — invoices were late and frequently disputed.
Customers had to email or call to check stock levels, order status or receipts — eating into the operations team's day.
Shipping labels were generated in separate carrier portals, with no automatic tracking back into the order system.
Onboarding a new client took weeks because each DC had its own put-away and picking conventions.
03 / Solutions
Standardized inbound, put-away, picking and outbound workflows across every DC on Odoo Inventory with barcode scanning.
Built a custom billing engine on top of Odoo — storage by pallet/day, handling by line, value-added services per task — invoices auto-generated monthly.
Each customer gets a branded Odoo portal with live inventory, order status, receipts and downloadable invoices.
Integrated DHL, UPS, FedEx and regional carriers for label generation and tracking sync inside Odoo.
New-client onboarding standardized into reusable templates — put-away rules, pick strategies and SLAs cloned in hours, not weeks.
Live dashboards for inbound dock, outbound pick rate, accuracy and SLA performance per client.
A nightly model re-scores slot assignments by velocity and co-pick frequency — pickers walk shorter routes without anyone re-mapping the warehouse.

05 / Outcomes
Every DC now runs the same workflows — staff can be redeployed across sites without retraining.
Activity-based invoices generate automatically — billing disputes dropped from routine to rare.
The portal absorbs 70% of the inbound queries that used to hit operations.
New customers go live in days instead of weeks, accelerating revenue ramp.
