In short

Khobar's engineering firms and service contractors live on contracts: a scope, a crew, a certified invoice with retention held back. Aqid ERP tags every cost to the contract, holds the retention on the invoice, clears it through ZATCA and pays the crew with GOSI and the Mudad file. The Growth plan fits, at SAR 111 a month, with a 60-day free trial. Not built yet: There is no billing by percentage of completion and no timesheets: a progress invoice is one you raise for the amount certified, with the percentage complete recorded on the project for the report.

Business in Khobar, and the part Aqid ERP plays

Khobar, with Dammam and Dhahran, is where the Eastern Province's engineering consultancies, oilfield service companies and maintenance contractors keep their offices, close to the operators and the industrial cities they serve.

Their month is contract work certified and invoiced, with retention held until handover, and a payroll of engineers and technicians, many on site allowances. Aqid ERP gives each contract a budget and a percentage complete, holds retention on its invoices, and shows the profit per contract once payroll is allocated.

How a business in Khobar runs on Aqid ERP

Each contract its own P&L

Tag invoices, subcontractor bills, equipment hire and payroll to the contract. The profit and loss by project shows margin before the contract ends, against the budget you set.

Retention on invoices

A certified invoice can hold the contract's retention percentage back; the retained amount sits in its own account until the release invoice.

Payroll with allowances

Site and transport allowances, overtime and claims run through monthly payroll with GOSI and the Mudad WPS file, and payslips in Arabic and English.

Approval on purchases

Subcontractor and hire orders above your limit wait for a second approver; the bill is matched to the order.

A month at a engineering services contractor in Khobar (example)

Say a engineering services contractor in Khobar invoices SAR 950,000.00 of maintenance work certified in October, all at the standard rate. That is SAR 142,500.00 VAT, SAR 1,092,500.00 in total, on tax invoices cleared through ZATCA or simplified invoices reported to it.
A supplier bills SAR 310,000.00 plus SAR 46,500.00 VAT for a subcontractor's crew and equipment hire, posted against a purchase order and tagged to the plant-maintenance contract.
Payroll for 36 staff runs with GOSI contributions and a WPS salary file in the Mudad layout, and its cost is posted to the books from the same run.
The VAT return shows SAR 142,500.00 output VAT and SAR 46,500.00 input VAT, so SAR 96,000.00 to pay before any other purchases. Each box opens to the invoices and bills behind it.
These figures only show the arithmetic. How VAT applies to your supplies is for your tax adviser, set up before you start invoicing.

The rules in Saudi Arabia, and what Aqid ERP does with them

E-invoicing: ZATCA's Phase 2 reaches VAT-registered businesses in waves. Aqid ERP produces the UBL 2.1 XML, the XAdES signature and the QR code, clears tax invoices and reports simplified ones once your device is connected with an OTP from the Fatoora portal. It implements Phase 2 end to end and is tested against ZATCA's published rules; its listing in ZATCA's solution-provider directory is in progress.

VAT: the standard rate is 15%. The return is prepared from the books in ZATCA's layout, and every box opens to the invoices and bills behind it. Filing on the ZATCA portal stays with you or your adviser.

Payroll: GOSI contributions by nationality, a WPS salary file in the Mudad layout, end-of-service accruals and payslips in Arabic and English, posted to the books from the same run. Employee records carry document expiry alerts for iqamas and passports.

Zakat and income tax are not computed; the year-end statements they start from are kept as you work, for you or your adviser.
