From the paper trailer to the digital draw

Walk through any mid-sized construction office during draw week and you'll find a scene that hasn't fundamentally changed since the 1990s: a project accountant with three monitors, a stack of printed G703s, a highlighter, and a spreadsheet open to a tab called 'PAY APP 12 - FINAL v3 - USE THIS ONE.' The tools around them - Procore, Viewpoint, Sage - manage the project. The pay application itself is still checked by hand.

What digital procurement actually changed

The construction software stack is good at capture and terrible at review. A subcontractor uploads an invoice to a portal and the system routes it. The general contractor's PM enters a schedule of values and the system stores it. But when it's time to certify what should be paid, the system hands the reviewer a dashboard of documents and says: you figure it out. The bottleneck moved from filing cabinets to file servers, but the cognitive load on the reviewer stayed exactly where it was.

Uploading a pay application to a portal isn't processing it. Processing it means a human has verified every number's provenance - and been given the tools to do it in minutes, not hours.

The jobsite trailer is the hardest office to change

Adoption problems in construction aren't about Luddism. They're about time. A superintendent approving timecards at 5:30 AM and a PM reviewing submittals at 8 PM are not going to learn a new workflow unless it demonstrably saves them time on the first use. The tools that win adoption are the ones that meet people where they already work - in PDFs, in emails, in the quick judgment call between site walks - and make the existing workflow faster rather than demanding a new one. That's a higher bar than the software industry usually builds for. It's also the right one.
