Free tools for Saudi contractors

Yes — no sign-up, no email wall, no usage limit and no trial that expires. The calculators run entirely in your browser and the template is a direct download. They exist because a contractor checking one certificate or one salary cost should not have to book a demo to do it, and because people who find a tool useful tend to remember who built it.

It takes your contract terms and this period's measure and produces the certificate: retention held against the contract cap, the advance recovered pro-rata, the gross and net cumulative, what is payable this period and the VAT on it. Every figure comes from your own contract — nothing is assumed, and the cap breach is flagged on the certificate where it happens.

The contribution base and its ceiling, what is deducted from the employee, what the employer adds, and the true monthly and annual cost to company — for one person and across a headcount on the same profile. The contribution rates are inputs rather than a published table, because they differ by scheme and change; confirm yours with GOSI.

Yes. There is a free Arabic-and-English IPC template on the calculator page: a right-to-left workbook with a BOQ measure sheet and a certificate block whose formulas carry retention with a cap, pro-rata advance recovery and VAT on the net. The blue cells are inputs and the rest are formulas, so it stays correct when you change a term.

No. The calculators are client-side: the figures you type never leave the page, are not sent to a server, and are not stored between visits. Close the tab and they are gone. That is deliberate — contract values and salary figures are not things anyone should have to hand a vendor's website to do arithmetic.

Yes, both calculators and the template are fully bilingual. The Arabic versions live at the same paths under /ar/, mirror right-to-left properly, and use Western digits throughout, as the rest of the site does. The downloadable template is bilingual in one file rather than two, so an Arabic and an English reader can work from the same sheet.

They do — the layout stacks on a narrow screen and the number fields use a numeric keypad. The workbook template is best opened on a desktop, as any spreadsheet with formulas is, but the calculators themselves are built to be usable standing on a site with one hand.

Please do. There is no licence, no attribution requirement and no limit on who follows the link. If it saves a quantity surveyor an argument about a retention cap or settles a payroll budget question, that is the tool doing its job — and it is a fair trade for the occasional reader who then wonders what else we build.

IntellaQ Flow — a creative growth agency and software studio in Riyadh that builds ERP and CRM systems for Saudi businesses, including the construction modules behind Tender Mind AI. The calculators are the arithmetic from those modules, pulled out and made free to use without any of the rest.

These calculators cannot carry an audit trail, and that is the honest limit. A calculator does not know which BOQ lines were measured, who approved the variation, what the back-to-back subcontract certificate says, or whether the resulting invoice actually cleared with ZATCA. For one number they are the right tool; across several live projects they stop being one.
