Important Note — Odoo Middle East ASP Approval in Progress
Please Note: Odoo Middle East is in the process of getting Approved as an ASP (Accredited Service Provider) for UAE e-invoicing. Once Approved, e-invoicing will be embedded within the Odoo Sales Module without any Add-On costs. Until that approval is confirmed, OESync by Perfonec is the recommended path to UAE e-invoicing compliance for all Odoo users before your mandatory deadline.

Perfonec handles the complete ASP integration as part of the OESync service — from ASP selection and appointment to API configuration, pilot testing, and go-live support. One partner. One product. Complete UAE e-invoicing compliance for Odoo.

UAE mandatory e-invoicing is approaching — 1 January 2027 for large businesses and 1 July 2027 for all other VAT-registered SMEs. If your business uses Odoo ERP, the question you are asking is: what do I need to do, and who handles the ASP? With OESync by Perfonec, the answer to the second question is simple — Perfonec handles it. You deal with one partner.

Odoo Versions Compatible with OESync
One of the most common questions UAE Odoo users ask is whether their existing version needs to be migrated to Odoo 18 before UAE e-invoicing compliance can be achieved. The answer with OESync is no. If you are on Odoo 16 or Odoo 17, OESync installs on your current version without any migration. Your existing Odoo data, workflows, customisations, and integrations remain unchanged. OESync adds UAE PINT AE XML and Peppol capability on top of your current Odoo installation.
| Odoo Version | OESync Compatible? | Notes |
|---|---|---|
| Odoo 16 |  Compatible | Full OESync compatibility — no version upgrade needed |
| Odoo 17 | Compatible | Full OESync compatibility — no version upgrade needed |
| Odoo 18 | Compatible | Latest Odoo version — full OESync support |
What Perfonec Handles — No External ASP Subscription Required
The ASP requirement is the single biggest source of confusion and friction for UAE Odoo users approaching e-invoicing compliance. 33 ASPs are pre-approved by the UAE Ministry of Finance — and selecting the right one for your Odoo version, invoice volume, and business type requires knowledge that most Odoo users in the UAE do not have and should not need to develop. With OESync, Perfonec makes this decision and manages the entire ASP relationship on your behalf.
| What Most Solutions Require from You | What Perfonec Handles for You with OESync |
|---|---|
| Find and evaluate 33 FTA-approved ASPs yourself | Perfonec selects the right ASP for your Odoo version and invoice volume |
| Submit ASP appointment paperwork independently | Perfonec manages the ASP appointment process end to end |
| Subscribe to ASP — recurring monthly cost to manage | Perfonec handles ASP — no separate external subscription for you |
| Complete ASP API onboarding to obtain credentials | Perfonec obtains and configures all ASP API credentials in OESync |
| Configure ASP API in Odoo yourself | Perfonec configures OESync with ASP client ID, secret, endpoint URL |
| Test ASP connection and resolve errors yourself | Perfonec tests and verifies full ASP connection before pilot phase begins |
| Manage ASP vendor relationship independently ongoing | Perfonec manages ASP — you contact only Perfonec for all support |
| Monitor ASP compliance updates independently | Perfonec monitors UAE e-invoicing updates and keeps OESync compliant |
How OESync Works — Peppol-Ready, ASP Integrated
| Step | What Happens | Who Does It |
|---|---|---|
| 1 | Create and confirm B2B invoice in Odoo 16, 17 or 18 — exactly as always | Your team — no change |
| 2 | OESync generates PINT AE XML automatically with all 17 mandatory fields | OESync automatic |
| 3 | OESync validates all 17 PINT AE mandatory fields before ASP transmission — errors caught first | OESync automatic |
| 4 | OESync sends validated PINT AE XML to Perfonec’s integrated ASP via secure API | OESync automatic |
| 5 | ASP validates and transmits invoice through UAE Peppol network to buyer | ASP via Perfonec |
| 6 | Peppol network delivers invoice to buyer’s accounting system or ASP | Peppol network |
| 7 | Transmission status — sent, received, or rejected — visible in Odoo dashboard | OESync dashboard in Odoo |
Steps 2 through 7 are fully automatic after Perfonec completes the one-time OESync setup. Your team performs only Step 1 — exactly what they do today. The invoice confirmation in Odoo triggers the complete UAE e-invoicing chain automatically and invisibly. Your team never needs to think about PINT AE XML, the ASP, or the Peppol network.
