Evidence arrives after completion
Site work is reported complete, but measurements, photographs or supporting documents are not assembled. Commercial teams cannot prepare a defensible bill pack.
EPC client billing software
Convert completed project work into approved bills faster
Built for quantity surveyors, commercial managers and project directors. Connect billable quantities and milestones with measurement references, documents, approvals, invoices and collections without treating software records as engineering certification.

What is epc client billing software? EPC client billing software connects completed quantities or milestones with measurement references, supporting documents, approval status, invoice submission, due dates and collections. It helps commercial teams identify billable and unbilled work, while authorised engineers, clients and commercial reviewers remain responsible for measurements and certification.
The operational problem
Why completed work remains unbilled
Approval ownership is unclear
A running account bill or milestone submission moves through email with no current owner. Follow-up begins only when cash planning is affected.
Collections lose project context
Invoices and due dates sit in finance records while project teams track certification separately. Leaders cannot distinguish unbilled work from billed-but-uncollected value.
Connected EPC records
Carry approved progress into billing and collection
The billing record links the agreed BOQ or milestone with completed work, measurement references, documents and reviewer status. Once authorised, the invoice and collection position remain visible beside the project.

Core capabilities
Controls your team can evaluate in a demo
Billable work
Compare available completed quantities or milestones with the billing plan. Show commercial teams where a billing review should begin.
Measurement context
Attach or reference measurements behind claimed work. Keep professional verification with authorised project and client teams.
Document readiness
Track the supporting documents required for a submission. Prevent an avoidable missing attachment from holding the entire bill.
RA bill records
Where configured, organise running account bill periods, prior values and current claims. Preserve the agreed commercial structure across submissions.
Approval status
Show who holds the next review and what remains pending. Give project leaders a practical follow-up list.
Unbilled visibility
Separate completed-but-unbilled work from submitted, approved and invoiced value. Improve cash-flow discussions with traceable status.
Collections view
Retain invoice dates, due dates and collection status in project context. Help commercial and finance teams coordinate follow-up.
Product walkthrough
From completed work to collected value
The billing workflow makes readiness, certification status and cash follow-up visible without automating professional approval.
- 1Completed work starts the review
- 2Evidence supports the submission
- 3Approval and collection remain distinct
Operational takeawayThe view gives authorised teams a shared record for the next decision; it does not replace physical verification or professional judgement.

Buyer questions
EPC client billing software FAQs
What is EPC client billing software?
It connects completed quantities or milestones with measurement references, supporting documents, approvals, invoices, due dates and collections for controlled project billing.
Can it show completed but unbilled work?
Where progress and billing records share project context, authorised teams can identify work reported complete that has not yet moved into a bill or approved invoice.
Does Supista certify engineering measurements?
No. Authorised engineers, quantity surveyors, clients and commercial reviewers remain responsible for measurement, certification and contractual approval.
Can running account bills be managed?
Running account bill periods, previous values, current claims and supporting records can be configured where that workflow is included in the agreed implementation.
Can teams track approval and collection separately?
Yes. Submission, certification, invoice and collection are separate states, helping teams distinguish operational billing delays from overdue receivables.
How can Lois help with client billing?
Lois can find available billable-work records, identify missing information and prepare summaries. Users review its output and all permissions and approvals remain in place.
