Contracting ERP Consultant, Saudi Arabia

Subcontract packages on large programs

On large Saudi projects, the main contractor often acts as much as a manager of packages as a builder. Civil works, MEP, facades, fit-out and specialist systems may each sit with a different subcontractor, some chosen by the contractor and some influenced by the client. Terms are frequently drafted back-to-back with the main contract, including payment linked to receipt, retention, advance payment and performance security, and the main contract itself may follow a FIDIC-based form or the client's own conditions.

I design the package register so each subcontract holds its value, terms, securities, approved variations and certificate history, and links to the main contract items it supports. A commercial manager can then answer the questions that matter on a big job: what has been committed to each package, what has been certified to each subcontractor, what the client has certified to us for the same scope, and where the gaps are. Where subcontracts tie payment to receipt from the client, the record shows which client certificate releases which package payment. The legal effect of those clauses is for your advisors to judge; the system's job is to hold the facts. I capture all of this through process mapping with your commercial and finance teams.

Certificates, e-invoicing and credit notes

ZATCA e-invoicing changes how contracting values become tax documents. An approved progress certificate normally leads to a tax invoice, and when a later certificate reduces an earlier valuation or a variation is rejected, the correction needs a properly issued credit or debit note rather than a quiet adjustment in a spreadsheet. The same applies downstream: subcontractor tax invoices should match what you approved, and the deductions you apply have to be documented in a form your accounts team can defend.

When VAT applies to retention, advance payments and back-charges is a question to settle with your tax advisor. My design goal is a system that records each element separately and can support the treatment you are advised to apply, whether a back-charge is netted on a certificate or invoiced to the subcontractor. In the requirements, I specify that invoices are generated from approved certificate values, that every credit or debit note points back to the invoice it corrects, and that the e-invoicing solution used with the ERP is tested on real certificate scenarios during UAT. For the wider e-invoicing picture across all industries, see my Saudi ERP consulting page.

Variation orders, claims and delay records

Variation orders on Saudi projects can wait a long time for approval from the client or its project management consultant, especially where budgets must be revised first. Meanwhile subcontractors are instructed, materials are bought and labor is committed. A contractor needs to see, per project, the value of change that is instructed but unapproved, and how much of it has already been passed to packages.

I set up variation records with separate statuses and values for the client side and each affected subcontract, with Arabic and English documents attached where relevant. Claims for delay and disruption need a parallel trail: notices issued and received, event dates, affected work, cost captured and the subcontractor claims each event generated. Interpreting contracts and drafting claims is work for your claims team or external advisors, and well-structured records make that work faster and more reliable. The same records support the final account, which on long projects can involve many variation orders and partial approvals. The broader project cycle, including certification and guarantee tracking, is described on my Saudi construction ERP page.

Systems, data migration and independent advice

Saudi contractors often keep finance in a regional accounting product or a legacy ERP, while the commercial team keeps packages, certificates and variation logs in Excel. Moving to a new ERP mid-project is the hardest part: each open package needs its contract value, approved variations, cumulative certified value, advance recovered, retention held and back-charges migrated so that the next certificate is correct. I plan that through data migration work, with reconciliation sign-off package by package.

I do not sell or resell any platform. I compare general ERPs and construction-focused solutions on your own scenarios, including a package certificate with deductions, a reduced client certificate with its credit note and a variation flowed down to a subcontractor. You see exactly where each option needs configuration, add-ons or custom development.
