Construction Invoicing & Commercial Support Services
KKJ Consultants provides specialist invoicing and commercial support, aligning applications, certificates, and invoices to ensure accurate and recoverable payments.
What Is Invoicing & Commercial Support?
Invoicing and commercial support ensures that all submitted applications, payment certificates, and invoices are properly prepared, contract-compliant, and fully recoverable. This service protects cash flow, minimises disputes, and maintains strong commercial relationships with clients and subcontractors.
Benefits of Invoicing & Commercial Support:
- Accurate Applications: Ensures all payment applications are prepared correctly and substantiated.
- Invoice Alignment: Certificates and invoices are fully reconciled with contract terms and project records.
- Recoverable Payments: Structured approach maximises entitlement and minimises the risk of underpayment.
- Contract Compliance: Adheres to JCT Design & Build and NEC4 contractual procedures.
- Cash Flow Protection: Ensures timely payments and reduces financial exposure.
How This Service Works:
- Payment Applications: Preparation and submission of contract-compliant applications for work completed.
- Certificate Reconciliation: Align invoices with interim certificates and valuations to ensure consistency.
- Invoice Preparation: Creation of detailed, substantiated invoices that reflect the work completed, variations, and adjustments.
- Commercial Oversight: Monitoring of payments, resolving discrepancies, and providing ongoing commercial support.
- Record Maintenance: Audit-ready records for all applications, certificates, and invoices to support entitlement and dispute resolution.
Why Invoicing & Commercial Support Is Essential:
Accurate invoicing and commercial oversight are critical for maintaining healthy cash flow, avoiding disputes, and ensuring all entitlements are properly recovered. Without structured support, projects risk delayed or reduced payments.
