Trax + Shopify
Trax Shopify COD Reconciliation
Parcelo connects to Trax via API and reconciles every cash-on-delivery order against your Shopify store.
Reconcile Trax COD orders on Shopify
Add your Trax API credentials once in Parcelo Settings; Parcelo follows every fulfilled tracking number.
However the data comes in, Parcelo marks delivered COD orders paid, shows the delivery charge and tax Trax deducted on every order, flags refused deliveries as return-risk, and reports what Trax still owes you — all from your Shopify admin, read-only on the courier.
Good to know: Reads delivery status and paid settlements directly from Trax (Sonic).
How Parcelo handles Trax
- Tracking: Parcelo pulls status for your Trax (Sonic) parcels automatically and maps Trax's status descriptions to delivered, returned, in transit or failed. A 'Shipment - Misrouted' update is treated as still in transit, not as a failed delivery.
- Settlement: once Trax marks a parcel paid, Parcelo records it as settled, so delivered orders stop showing as owed.
- History: settlements are matched over a six-month look-back, so older delivered parcels don't stay stuck as overdue.
- Mark COD orders paid automatically the moment they're delivered
- See Trax charges, tax and net remitted per order
- Per-period reports with CSV export
- Screen high-return (RTO) customers before you ship again
