Rwanda RRA EBM Purchase Registration
Verify that supplier invoices are EBM-certified before you claim input VAT — BYOK connector for the Rwanda Revenue Authority EBM
In Rwanda, input VAT is only deductible when a purchase is supported by a valid EBM (Electronic Billing Machine) receipt carrying a verifiable SDC electronic signature. This module makes that check a first-class part of your vendor-bill workflow: it parses the supplier's EBM receipt footer, validates the Rwandan identifiers, verifies the receipt signature against the Rwanda Revenue Authority (RRA) EBM, and tells you exactly how much input VAT is reclaimable — all using your own RRA credentials and device (bring-your-own-key).
Verify before you claim
Paste the SDC footer printed on a supplier's EBM receipt and the module extracts the SDC ID, MRC, receipt number and receipt signature automatically. One click verifies the receipt signature against the RRA EBM Verificator: a green result unlocks the input-VAT claim, a red result blocks it and prompts you to contact the supplier.
Correct Rwandan VAT logic
Built on the official RRA EBM tax categories: A exempt, B standard-rated 18%, C zero-rated / export, and D non-VAT supplier. Only verified category B purchases carry reclaimable input VAT, and the module re-checks the 18% arithmetic on every line.
Identifier validation
Structural validation of the 9-digit Rwanda TIN, the SDC ID (Sales Data Controller serial) and the MRC (Machine Registration Code) on companies, partners and bills — no invented check digits, only the formats the RRA publishes.
Purchase registration (BYOK)
Generates the canonical EBM purchase-registration payload (supplier TIN, SDC ID, MRC, receipt number, receipt signature, per-category tax breakdown and totals) and transmits it to the EBM back-office endpoint you configure, using your own API key and device ID. Every call is written to an append-only transport log.
Features
| Receipt-footer parser | Auto-extract SDC ID, MRC, receipt number, signature and supplier TIN from a pasted EBM receipt footer. |
| RRA EBM verification | Verify the SDC receipt signature against the RRA Verificator; mirrors the green-tick / red-cross result. |
| Input-VAT eligibility engine | Decides line-by-line whether input VAT is reclaimable and computes the total reclaimable amount. |
| EBM tax categories A/B/C/D | Maps Odoo taxes to the official RRA EBM categories with the 18% standard rate. |
| Purchase-registration payload | Deterministic, canonical JSON with a SHA-256 audit hash for every registered purchase. |
| BYOK connection | Your TIN, API key and device ID; user-editable RRA endpoints; nothing is bundled. |
| Transport log | Append-only audit trail of every EBM call (method, URL, HTTP status, response excerpt). |
| Vendor-bill integration | Dedicated Rwanda EBM page, status field, stored search filters and a quick-verify wizard. |
How it works
- Set your company Rwanda TIN and enable RRA EBM purchase registration.
- Configure an EBM connection with your own API key, device ID and (editable) RRA endpoints.
- On a vendor bill, paste the supplier's EBM receipt footer and parse it.
- Click Verify Receipt — the SDC signature is checked against the RRA EBM.
- If verified, the reclaimable input VAT is computed; optionally register the purchase with the RRA.
Boundary & data protection
This module is a format generator and bring-your-own-key transport. It is not a certified SDC device and does not impersonate one: it builds the payload your own certified device / RRA account consumes and verifies receipt signatures using your credentials. Data is sent only to the RRA EBM endpoint you configure; your credentials never leave your database.
Compatible with Odoo 18 and 19, Community and Enterprise. Built on the standard Accounting (account) module — no Enterprise-only dependency.
