We understand what makes construction AP different

Built to make life easier for construction finance teams, because we know how you work.
Retention invoices
Retention withheld and released across project milestones. Hard to match, easy to miss, and the first thing an auditor asks about.
Subcontractor billing
Dozens of subcontractors on site, each invoicing differently, each needing sign-off from a different foreman. Chase the wrong person and it stalls.
Variation orders
Invoices that don't match the original PO because scope changed mid-project. Someone has to sort it by hand.
Fair Payment obligations
Real pressure to pay on time. And to prove it, with an audit trail built for compliance reporting.

Here's what our customers say...

Payment processing speed
"Since partnering with Open ECX, we've seen a reduction of 6 days in our payment processing time, despite no increase in staff numbers and an increase in the number of invoices processed."
Richard McDermott, Assistant Accountant, Farrans
Three-way matching efficiency
"It previously took 15 minutes to process one document into our Sage system. Now with Open ECX, it takes a minute, so the efficiencies there are massive."
Lee Carmichael, Group Director of Finance, MadiganGill
COINS automation at scale
"We're probably looking at about 12,000 invoices going through Open ECX, plus about 20% manual invoices. We're literally just minutes away from clicking through and authorising them in COINS."

Frequently Asked Questions

Does Open ECX handle retention invoices and variation orders?

Yes. Retention held and released across project milestones, and invoices that don't match the original PO because scope changed, Open ECX captures and validates both automatically so nothing slips through at audit.

Can I control workflows and approvals?

Definitely. Open ECX enables you to define custom business rules and approval workflows.  These can be multi-level, ensuring the right people sign off on invoices. Approvals can be managed within the portal or through email, depending on your preference. Potential errors are automatically flagged and invoices routed back to suppliers before they hit your finance system, saving time and preventing inaccurate payments.

Can your invoice processing software handle large volumes of transactions?

Absolutely! Our scalable platform seamlessly handles any volume, including multi-line invoices and orders, growing alongside your organisation without compromising efficiency or speed.

Which construction ERP systems do you integrate with?

COINS, IFS, SAP and more. If your finance team runs it, chances are we already talk to it, and we manage the integration so subcontractors see no disruption.

Do my subcontractors need to change how they invoice?

No. Subcontractors keep sending invoices exactly how they already do, PDF, EDI or email. Open ECX converts and validates everything behind the scenes.
