Stop fielding texts while you're driving.
Every question from the field, the office, or the GC has the same answer: it's in PM4Subs. Bids, specs, change orders, photos, and field tasks — one place, on every phone on your crew.
Your GC has Procore. The owner has attorneys on retainer. You have a good memory and a group text. When a change order goes sideways, whoever has the better paper trail wins — and right now that's not you. PM4Subs closes that gap.
Lost each year in undocumented change orders. Not because the work wasn't done. Because they couldn't prove it when the GC pushed back.
These are the texts that make you pull over. We built PM4Subs to stop them.
Digging through hundreds of emails trying to find critical project information that's buried somewhere.
Camera roll, texts, emails, WhatsApp. Good luck finding that specific photo from three weeks ago when the GC asks for it.
Multiple jobs, different deadlines, submittals, requirements. It's all in your head, not in a system.
They're on site and need plans or specs, but you're in a meeting. No way to get them what they need.
Lost revenue because you can't remember what extras you did last month. By billing time, half of it's forgotten or unprovable.
You should be running jobs and managing crews — not hunting for paperwork you know you had somewhere.
One photo before the extra work. One after. A note with the date and who authorized it. That's a change order that holds up when the GC pushes back.
PM4Subs makes documentation the default, not the exception. Every job photo is tagged with the project, date, and GPS location — automatically.
Disputed change orders go to whoever has the better documentation.
Right now that's your GC. PM4Subs changes that.
Built by masons who got tired of the chaos

PM4Subs is project management software built specifically for subcontractors. It helps you track bids, jobs, change orders, specs, field tasks, and tools in one place so you spend less time chasing information and more time running work.
No. PM4Subs works for any trade — masonry, concrete, framing, drywall, steel, and more. It was designed by a masonry subcontractor, but the workflows fit most trades.
Procore is built for general contractors. It's powerful, expensive, and designed around owner meetings and drawing logs. PM4Subs focuses on what subcontractors actually need: change order documentation, field task tracking, spec review, and staying organized without a full-time office staff.
Yes. The Spec Analyzer is built for subcontractors who get handed 2,000-page spec books. Upload the PDF and pull out the sections that matter for your trade — materials, accessories, submittal requirements — without reading the whole thing.
No. PM4Subs works alongside your existing accounting system. It organizes jobs, tasks, specs, and field documentation so your billing is cleaner and easier — but it's not an accounting platform.
Yes. PM4Subs is built mobile-first so foremen can see job tasks, upload photos for change order documentation, and update the office from the field without fighting a complicated app.
Simple pricing. No long contracts. No surprise fees. Free during beta.
