Most of a main contractor's cost runs through subcontracts. Manage each package from award to final account with the same discipline you apply to client billing.
A UAE main contractor should manage each subcontract package in the ERP from prequalification to final account: documents, enquiry and quotes, comparison and award, a committed subcontract order, monthly applications measured and certified against progress, back-charge deductions, payment, and retention release. This prevents over-certification, missed back-charges and expired trade licences or insurance, while paying genuine applications on time.
Construction subcontractor management UAE main contractors need covers a large share of project cost. Building contractors in Dubai, Abu Dhabi and the northern emirates commonly subcontract MEP, facade, waterproofing, joinery, piling, landscaping and specialist finishes, and keep self-performance mainly for civil and structural work. Each package has its own subcontract agreement, scope, rates, payment terms, retention, insurance and documentation, and each one generates monthly payment applications.
When these packages are managed in email and spreadsheets, the main contractor loses control in both directions. Subcontractors are over-certified because their applications are approved without checking measured progress, back-charges for materials, equipment or labour supplied by the contractor are never deducted, and expired trade licences or insurance policies go unnoticed. At the same time, genuine subcontractor payments are delayed by paperwork, which strains relationships and site productivity.
An ERP brings subcontracts into the same system as the main contract. Packages are bought out through construction procurement, committed values feed project costing, and retention withheld links to the retention register. The commercial team can then compare what is certified to each subcontractor with what the client has certified for the same work.
These problems appear in most main contractors still running subcontracts outside their ERP.
Subcontractor applications are approved on the subcontractor's own figures without a site measurement check. The contractor pays ahead of progress and ahead of what its client has certified.
Materials issued from the contractor's store, shared scaffolding, equipment hire and cleaning are meant to be charged back. Without a contra charge register, they are rarely deducted.
Trade licences, insurance policies and safety approvals expire mid-project. When a subcontractor's workers are not covered, the main contractor carries the risk.
Subcontract values and approved variations are not entered as commitments, so cost reports show only what has been paid and understate true project exposure.
With no consolidated history of certificates, variations and deductions, closing a subcontract account can take months of reconciliation.
This is the package life cycle we configure for main contractors.
One shared database: every step updates stock, finance and reports in real time.
Subcontract management combines supplier, purchasing, project and finance functions.
Company details, trade categories, TRN, trade licence, insurance policies and expiry dates, with a supplier portal where available.
Enquiries to several subcontractors, quotation comparison and award approval for each work package.
Awarded value, scope, rates, retention, advance and payment terms stored as a commitment against the project budget.
Monthly subcontractor applications measured against the subcontract lines with previous, current and cumulative values.
Contra charges for materials, equipment, labour or rectification logged as they happen and deducted on the next certificate.
Supplier invoices matched to certified values before payment, with retention payable held separately.
Committed, certified and paid subcontract cost visible per cost code.
Subcontract agreements, variation instructions and correspondence attached to the package.
Project managers and commercial managers use this view to compare subcontractor progress, payments and exposure.
Subcontracting in construction is mostly built on purchasing and project features. Capabilities vary by edition, so confirm details for yours.

Subcontract control relies on information from site, procurement and finance.
Configuration should support these UAE requirements. This is not legal or tax advice; confirm with your advisors.
Input VAT on subcontractor invoices can only be recovered with a valid tax invoice showing the supplier's TRN and prescribed details. Check TRNs at onboarding and store them on the subcontractor record.
Once the e-invoicing mandate applies, subcontractor invoices will arrive as structured PINT AE documents through ASPs. The ERP should be ready to receive and match them to certified values. Check the latest Ministry of Finance and FTA guidance.
Subcontractors' workers are paid under their own employers' WPS arrangements. Many main contractors ask for evidence of compliance as part of prequalification and periodic review; record it against the subcontractor.
Keep subcontract agreements, certificates and deductions for at least five years, or seven for real estate, under Cabinet Decision 74 of 2023.
General information, not tax or legal advice. Rules change; confirm current FTA, MOHRE and Ministry of Finance guidance with your advisor.
The main gains are tighter payments and fewer surprises at final account.
Certificates are based on measured progress and compared with the client's certification for the same scope.
Contra charges are recorded when they happen and deducted on the next certificate rather than argued over at the end.
Expiring licences and insurance are flagged before they lapse.
Subcontract values and variations appear in cost reports from the day of award.
Typical ranges for a contractor running several live projects; more packages mean more data to load.
Durations are typical ranges; your plan is agreed after discovery.
List live subcontracts, document current certification and deduction steps.
Set up subcontractor master, package procurement, certificates, back-charges and approvals.
Enter running subcontracts with cumulative certified values, deductions and retention.
Process one cycle of subcontractor applications in the ERP with close support.
Open the supplier portal where used and finalise dashboards.
We configure the system for the rules UAE businesses report against, and test it before go-live.

Ask an ExpertOdoo, ERPNext and Zoho offer supplier or customer portals, and Dynamics 365 can use Power Pages or partner portals. The scope of what a subcontractor can submit depends on configuration.
Each contra charge is logged against the subcontract with the reason, quantity and value, often linked to a store issue or equipment log. Approved back-charges are deducted on the next payment certificate or raised as a debit note.
In most ERPs, yes: a subcontract is a purchase order with service lines, extended with retention, advance and certificate fields. That keeps commitments visible in project cost.
Map subcontract lines to the main contract BOQ items they cover. The dashboard can then show where a subcontractor has been certified more than the client has certified for the same scope.
Labour supply agreements are usually managed with timesheets rather than measured certificates. See construction workforce management and construction timesheet software.
Contractors with many packages often prefer Odoo or Dynamics 365 for their purchasing depth; see Odoo for construction companies. We implement Zoho, Odoo, ERPNext and Dynamics 365 and recommend by fit.
