EasyPost Lowest Delivery Rate
Automatically rate-shops across all your active EasyPost carriers on every delivery order, selects the cheapest rate, updates the carrier on the picking, and logs all available rates to the chatter — so you never overpay for shipping.
Automatic Rate Shopping
On every delivery order, all active EasyPost carrier accounts are queried simultaneously. The module compares rates and selects the lowest automatically.
Dynamic Carrier Assignment
The winning carrier is automatically set on the stock picking. No manual carrier selection needed — the best rate is applied before the shipment is created.
Full Rate Logging to Chatter
All available rates from every carrier are posted to the picking chatter. Full visibility into what each carrier would have charged for complete audit trails.
Zero Manual Work
Fully automatic — triggered on delivery order confirmation. Warehouse staff never need to compare rates or switch carriers manually.
Multi-Carrier Support
Works with all carriers available through your EasyPost account — UPS, FedEx, USPS, DHL, and any other carrier you have enabled in EasyPost.
Lightweight Integration
Depends only on stock and delivery_easypost. No extra configuration tables or UI overhead — installs and works immediately.

Does this work with all EasyPost carriers?
Yes. The module queries all delivery carriers configured in Odoo that use the EasyPost provider. Any carrier enabled in your EasyPost account and added as a delivery method in Odoo will be included in the rate comparison.
What happens if EasyPost returns no rates for a carrier?
Carriers that do not return valid rates (e.g., package dimensions not supported, service unavailable for destination) are skipped silently. The lowest rate among carriers that did return rates is selected.
Can I exclude specific carriers from rate shopping?
Yes — simply set a carrier's status to Unpublished in Inventory → Configuration → Delivery Carriers. Inactive carriers are excluded from rate comparison.
