ETA e-invoicing is now the cost of doing business in Egypt. Most SAP customers know the deadline — fewer know how to land it cleanly inside S/4HANA or ECC without disrupting the order-to-cash flow. This is the checklist we run on every engagement.
The four workstreams
- →Master data: tax codes, item coding (GS1/EGS), and customer registration
- →Document model: mapping SAP billing documents to the ETA JSON schema
- →Integration: signing, submission, and acknowledgement back into SAP
- →Operations: monitoring, exception handling, and reprocessing workflows
Common pitfalls
- →Treating e-invoicing as an IT integration instead of a finance process change
- →Underestimating master data cleansing — usually 40% of the timeline
- →Missing the e-receipt (Phase 2) scope at the POS layer
- →No clear ownership for daily monitoring once the project ends
A workable 90-day plan
Weeks 1–3: assessment and master data baseline. Weeks 4–8: build and integration with the ETA portal in sandbox. Weeks 9–11: parallel run and exception management. Week 12: cutover with a hypercare squad in place. Done right, this is a finance-led program with IT as a partner — not the other way around.
