How It Works

Oman PEPPOL 5-corner delivery and
OTA reporting flow.

Faturathi receives ERP invoice data, validates it, converts it to the required format, sends invoice data through PEPPOL, and reports tax data to OTA.

Corner 1

Supplier ERP

ERP / billing system creates invoice data.

Corner 2

Faturathi ASP

Validate, transform, route, submit, and track status.

PEPPOL

AS4 / SMP Network

Secure invoice exchange between access points.

Corner 3 & 4

Buyer ASP → Buyer ERP

Buyer receives invoice and delivery acknowledgements are returned.

Corner 5

OTA — Oman Tax Authority

Tax data document submission, validation response, status, and reporting audit trail.

Compliance Challenges

Your ERP alone may not be enough.
Your service provider partner matters.

01

ERP Data Readiness

Invoice data can be spread across ERP, POS, billing systems, spreadsheets, and custom databases.

02

Field Validation

Mandatory and conditional OTA/PEPPOL invoice fields must be validated before submission.

03

VAT Accuracy

Tax category, amount, rounding, currency, and totals need strict validation to avoid rejection.

04

Compliance Updates

Validation rules, schemas, reporting formats, and OTA requirements may evolve over time.

05

PEPPOL Connectivity

SMP lookup, AS4 delivery, buyer access point routing, and status responses must be managed properly.

06

Rejection Handling

Failed validations, MLS responses, retries, and audit logs should be visible to operations teams.

Readiness Roadmap

Move from assessment to production
with a controlled rollout.

Step 01

ERP Assessment

Review current invoice sources, VAT logic, data quality, and integration options.

Step 02

Field Mapping

Map ERP output to required OTA/PEPPOL invoice structure and validation rules.

Step 03

Connector Setup

Connect API, SFTP, CSV, Excel, JSON/XML, or custom data extraction to Faturathi.

Step 04

Go Live & Support

Activate PEPPOL/OTA reporting workflow with monitoring, support, and audit logs.
