Project description:
"I need a developer who can link our ERP system directly to the ZATCA platform through its official API. The integration must enable three core actions:

• Submit invoices in real time
• Retrieve tax data on demand
• Validate transactions before they are posted

Scope
1. Review our existing ERP architecture and advise on the most efficient connection points.
2. Build a clean, well-documented API wrapper that handles authentication, error logging, and versioning.
3. Implement the three functions above, returning clear success or failure responses that map to our ERP’s workflows.
4. Provide a functional prototype in a staging environment, followed by production deployment once tests pass.
5. Deliver concise technical documentation and a hand-over walkthrough for our internal team.

Key considerations: adherence to ZATCA’s security requirements, graceful handling of API rate limits, and future maintainability. If you have completed similar Gulf tax integrations, please reference them so I can assess fit quickly." (client-provided description)
