Practical EPC guide
How to reduce delayed billing in EPC projects
Connect completed work, measurements, documents and approvals so EPC invoices move sooner and cash-flow risks become visible.
Short answer: Make billable work visible every week, define the evidence each bill needs and give every pending measurement, document and approval a named owner and due date.
Remember these three points
- Find billable work weekly
- Complete evidence before cut-off
- Track every approval owner
Find the work that is ready to bill
Compare completed quantities and achieved milestones with the contract billing plan. Do this weekly, not only at month-end, so missing evidence is still recoverable.
- Completed quantities
- Achieved milestones
- Agreed billing rules
- Unbilled value
Build the billing pack as work progresses
Measurements, certificates, photographs and client instructions should stay linked to the work. Waiting until billing day turns small gaps into avoidable delays.
- Approved measurements
- Completion evidence
- Required certificates
- Change and instruction records
Give each delay an owner
A pending approval without an owner is not a status. Record who must act, when it became pending and the effect on the planned invoice date.
Connect collections with project obligations
Track invoice submission, acceptance, due date and collection beside upcoming vendor and subcontractor payments. This gives management an earlier view of cash pressure without treating forecast collections as cash received.
Common questions
What usually delays EPC client billing?
Common causes include incomplete measurements, missing certificates, unresolved change records, unclear milestone status and approvals that have no visible owner.
Should completed work automatically become an invoice?
No. The system can identify potentially billable work and assemble supporting records, but authorised teams should confirm contract terms, measurements and approvals before invoicing.
