Technically the e-Waybill resembles the e-Invoice, but its operational impact is far greater. An invoice is issued in accounting; a waybill is issued at the loading dock, at the moment of shipment.
01. The Critical Difference: Timing
The e-Waybill must reach the tax authority and be acknowledged before goods physically leave. Which means when the system is down, the truck waits. Infrastructure continuity is therefore more critical than on the e-Invoice side.
02. The Warehouse Link
Waybill lines must match the quantity actually picked in the warehouse. In firms integrated with a WMS the waybill is created automatically as picking completes; without integration data is entered twice and discrepancies appear.
03. Partial Shipments
When an order is split, a separate e-Waybill is issued per shipment. The ERP must track the order-shipment-waybill chain at line level; otherwise remaining quantities are tracked by hand.
04. Cancellation and Rejection
The buyer can reject an e-Waybill, or goods can come back as a return. The return process must have a defined counterpart on both the stock and the document side. Projects that go live without testing this scenario hit trouble in the first week.
05. Carrier Details
Plate, driver and carrier details are mandatory fields in the document. If you don't collect them on the shipping screen, the operator types them every time, and error rate and duration grow from there.
06. Outage Plan
What happens during a tax authority or integrator outage must be written down. The right to continue with printed waybills and the notification steps that follow should be ready in the hands of the operations team.
