Software for MEP contractors in Saudi Arabia
An MEP package is three trades in one contract: electrical, plumbing and HVAC priced together, claimed together, and delayed together if its paperwork slips. For a small firm carrying such a package the discipline is single: a clean bill of quantities, claims that measure what is actually installed, and tax invoices that respect the Kingdom's e-invoicing path. InstaJack runs the paperwork around that — and says plainly where its e-invoicing role ends today.
How is an MEP package priced and won?
The package prices from the bill of quantities: electrical points and containment, plumbing points and pipework, HVAC units and ducting — each line at your rate, with the big supply items (boards, air-handling units, pumps) as named lines, never dissolved into percentages. A main contractor compares packages line by line; the package that survives line-by-line comparison is the one invited to negotiate.
Your price book holds all three trades' lines in one company book, so the package prices without chasing three spreadsheets, and variations measure against the same BOQ lines as the original.
Claims and e-invoicing for packages
Installed work is claimed by mustakhlas measuring executed percentages per line, with retention and an advance recovered across claims — the mechanics in the mustakhlas guide, at greater length in the advances and schedules guide.
Package tax invoices enter the two-phase e-invoicing world; InstaJack's position is stated on the ZATCA hub: the right fields are kept in your records today, and the connection to Fatoora is in development, not live. An MEP firm choosing software for a whole contract should read the software-choosing criteria before signing any promise.
What paperwork marks a disciplined MEP firm?
Material approvals and shop drawings, test and commissioning records per system, and a handover file that gathers all three trades as built. Small MEP firms bleed margin in the gaps between the three trades — an electrical point waiting on a duct, a duct waiting on an opening — and the record that ties quotes to work to claims closes those gaps before they become claims against you.

Is InstaJack right for an MEP contractor?+
For small MEP firms carrying the whole package or most of it — yes: BOQ pricing from one book, mustakhlasat and retention, and a record per contract. Giant MEP project management with its own planning departments is a different tool class.
Does InstaJack connect to Fatoora for MEP firms?+
Not yet — the connection is in development, not live, and that is stated across the ZATCA pages here. Your invoices carry the right fields and numbering today and your readiness is documented in the readiness guide; do not sign a contract on an undelivered integration promise.
Can I keep the three trades' lines separate in the book?+
Yes — the price book organises into sections, so electrical, plumbing and HVAC lines stay in their own sections while the package draws from one book.
