API development and integration

API development and system integration: connect ERP, accounting, HR, e-invoicing portals, weighbridges, PLC/SCADA and payment systems.

What is api development and integration? API development and integration connects separate software systems so data flows automatically instead of being re-typed. 3SD builds REST APIs and integrations between ERP, accounting, HR, government e-invoicing portals, plant equipment and payment systems.

Who it is for

  • Companies with disconnected software
  • Businesses that must connect to government e-invoicing portals
  • Plants linking equipment data to ERP

Api development and integration questions

Can you integrate with ZATCA e-invoicing in Saudi Arabia?

Yes. We build integrations to e-invoicing platforms, including ZATCA Fatoora requirements, as part of ERP and billing implementations. Final compliance should be confirmed with your tax advisor.

Can you connect a weighbridge to ERP?

Yes. Weighbridge readings can flow directly into stock, purchase and dispatch records, removing manual entry.
