Construction

The work is on site. The admin is three weeks behind.

In construction the margin does not sit in the contract sum but in what gets added and taken off during the project. Exactly that part — extra work, instalments, subcontractor invoices — is tracked by hand.

How it works today

Subcontractor invoices arrive in the payables mailbox, sometimes without a project number, often without a purchase order reference. Someone works out which project they belong to and whether the amount is right.

Meanwhile the site reports progress in one system and the instalment schedule lives in another. Whether what is being invoiced matches what has actually been built is a question nobody has time to answer weekly.

Extra work is agreed verbally on site and written down later, if at all. That is where the margin goes.

Who this is for
  • Contractors and construction firms with 10 to 100 staff
  • Projects invoiced in instalments
  • Regular subcontractors who each invoice in their own way
  • Extra work agreed on site and written down afterwards
What we build

What happens, step by step

  1. 1
    Collect the invoice

    From the payables mailbox or the supplier portal. PDFs, scans and invoices without a project number are processed just as well.

  2. 2
    Match to the project

    Purchase order number, project number, address or creditor — whatever is on it is used to find the right project and the right purchase order.

  3. 3
    Check against the instalment schedule

    The invoiced instalment is compared with the schedule and with instalments already paid. One that is already open or duplicated is flagged.

  4. 4
    Compare with reported progress

    What is being invoiced is laid against the latest completion report from site. Invoicing ahead of progress goes to a person.

  5. 5
    Separate extra work

    Extra work lines are recognised and separated from the instalment. Without a signed order they go to the site manager, with the day report attached.

  6. 6
    Post and queue

    What checks out goes into the bookkeeping against the right project and cost type and sits ready in the payment run. The rest waits, with the reason stated.

The hard cases

Where it goes wrong when it is built too simply

These are the questions we ask in the quick scan. If a supplier does not ask them, they surface later anyway — usually once there is already an invoice.

  • An invoice with no project number from a subcontractor working on four projects at once.
  • An instalment invoiced before the work it covers has been reported complete.
  • Extra work agreed verbally on site, invoiced without a signed order.
  • A retention percentage that has to be withheld and released later.
  • A subcontractor invoicing under a different legal entity after a restructure.
  • A collective invoice covering three projects with no split on it.

What it delivers

The payables round stops being archaeology. What matches goes through; what does not is on one list with the reason next to it.

The bigger effect is on extra work: because it has its own route with an approval step, it gets invoiced more often instead of quietly absorbed into the contract sum.

This is one of the harder ones, because every construction firm keeps its instalment schedule somewhere slightly different. That is what the Automation Check establishes first.
