Contracting ERP Consultant, UAE

Back-to-back subcontracts and pay-when-paid terms

A UAE main contractor often issues subcontracts that mirror the main contract: the same specification, a comparable payment cycle, retention, defects liability and performance security, sometimes with a pay-when-paid clause tying subcontractor payment to receipt from the employer. Nominated subcontractors add another layer, because the employer or engineer has a say in their selection and sometimes in their payment. How such clauses are interpreted under UAE law is a matter for your legal advisors, usually on the facts of a specific dispute.

For the ERP, I make sure each subcontract carries its payment terms, the clause type, its security requirements and a link to the main contract certificate lines it depends on. When a subcontractor certificate is ready for payment, the system shows whether the related main contract amount has been certified, invoiced and received. Finance can then apply your policy consistently, and the commercial team can explain a payment position to a subcontractor with facts instead of estimates. Advance payment guarantees and performance bonds received from subcontractors are recorded with expiry dates on the same record. All of this is written into the requirements so vendors are tested against it.

Subcontract certificates, back-charges and retention

Your subcontractors' applications deserve the same scrutiny the engineer applies to yours. A QS measures work, checks variations, values materials on site and deducts advance recovery and retention. Then come the back-charges: a share of site facilities and temporary utilities, cleaning and waste removal, security, scaffolding or hoist use, rectification of damage and, sometimes, labor or materials supplied on the subcontractor's behalf. In many firms these are agreed verbally on site and deducted inconsistently, if at all.

I specify a subcontract certificate that is cumulative, with each deduction as a separate line linked to its source record. Back-charges get their own register: originating event, notice issued, value, the subcontractor's acceptance or objection and the certificate where it was deducted. Retention held from subcontractors is tracked against the release conditions in their subcontract, which may differ from those in your own main contract. That difference matters at handover, when you might release a subcontractor's retention before the employer has returned yours. The UAE construction ERP page covers the main contract certificate cycle and job costing in more depth.

Variations, claims and the evidence trail

Variations in the UAE commonly move through a formal submittal process with the engineer: instruction or request, proposal, evaluation, approval and inclusion in a certificate. Approval can take a long time, and until it arrives, work and subcontractor commitments continue. Claims for extension of time and additional cost follow their own notice and submission requirements under the contract, and those requirements can be strict.

A sound ERP design separates variation values by status on both sides of the chain, so you can see what has been instructed to subcontractors without employer approval. It also gives claims a home: the notice, the event, the affected activities, the cost records and the related subcontractor claims, all linked and dated. Preparing claims and giving legal advice are not part of my role; designing records that support whoever does that work is, whether an in-house team, a claims consultant or legal counsel. When a dispute reaches arbitration, organized data saves time and expense. Correspondence and drawings usually stay in a document control system, referenced from the ERP records, and I define those links during ERP integration planning.

Group entities, VAT on deductions and independent advice

Contracting groups in the UAE often run more than one company, for example a mainland contracting entity alongside a free zone company, or a fit-out business beside an MEP business. Intercompany subcontracts between them need the same commercial controls as external ones, plus clean elimination in group reporting.

The VAT treatment of back-charges, retention invoicing and advance payments should be confirmed with your tax advisor. What I can do is design the system so that each deduction is recorded in a way that supports whichever treatment is confirmed, whether a back-charge is a deduction on a certificate or a separate tax invoice. Subcontract certificates in many UAE firms still live in spreadsheets beside an accounting package. I help decide what moves and what stays archived, compare platforms neutrally through vendor selection and review the implementation as it happens. For the general model, see ERP for contracting. Corporate tax and e-invoicing readiness are discussed on my UAE ERP consultant page, with broader context on the UAE hub. I deliver all of this remotely.
