Hinges checks every supplier invoice and order confirmation against your purchase orders, then posts the approved ones to your accounting software. Nothing auto-approves. Built by a construction firm owner, for specialty subcontractors.
Book a 30 min callThe competitive read. Vergo, inBuild, Field Materials, Adaptive, Beam and Nexus AP all sell into construction AP, and most of them are better resourced than you are. Almost all of them aim at general contractors and Procore-centric GC workflows. Your first line of copy says for specialty subcontractors. That's a narrower lane, and narrower is the only lane a three-person team should want.
Your own words are the best copy on the page. Your LinkedIn post from February put it better than a copywriter would: open invoice, find the matching PO in Procore, check the numbers, enter everything into QuickBooks, manually assign a GL code to every single line item, repeat 80 times. That's the evergreen email. It doesn't need a trigger to be true, and it's true for every account on the list.
| Layer | Signal | What fires it | Where the data comes from |
|---|---|---|---|
| Price pressure | Commodity move in their trade | The core input for a trade moves hard enough that quotes written months ago no longer hold. Copper is up roughly 26 to 30 percent year on year and structural steel 26.1 percent | AGC of America construction input cost releases, 15 July 2026 |
| Price pressure | Tariff action with an effective date | Section 232 duties sit at 25 percent on steel and up to 50 percent on aluminium, with 7.5 percent on copper products under Section 301. Each change has a date attached and a trade attached | AGC of America, July 2026, mapped to trade |
| AP strain | Open AP or project accountant req | A specialty sub posts for an AP clerk, AP specialist or project accountant. The responsibilities section recites the manual workflow line by line | Job boards and ATS feeds, filtered to specialty trades |
| AP strain | Req naming the accounting stack | The posting names QuickBooks, Procore, Sage or Foundation. This qualifies and disqualifies the account before anyone writes a word | Keyword match inside the job description body |
| AP strain | Role open past the 45-day mark | The req is still live weeks later, which means they can't fill it. The strongest version of the pitch is that you can't hire your way out of this one | Posting age tracked across repeat crawls |
| AP strain | New finance leader in the seat | A new Controller, CFO or Accounting Manager arrives at a qualified sub and wants a visible process win early | Job-change monitoring across the target list |
| Volume shock | Large project award | A named sub wins a job big enough to move their monthly invoice count. Material spend scales with awarded work, and invoice count scales with material spend | Public bid tabulations, construction project data, award announcements |
| Volume shock | Branch or territory expansion | A sub opens a second location or a new service area. Multi-location AP is where coding discipline breaks first | Company announcements, job postings by location |
| Volume shock | Trade roll-up activity | A sub is acquired or acquires. Consolidating AP across entities is an acute, dated, budgeted event and the window is short | Deal announcements and private equity portfolio pages |
| System change | Accounting migration in flight | A sub is moving off QuickBooks onto Intacct, NetSuite or Acumatica. Nobody adds a tool mid-close. They add it while the stack is already open | Job posts, implementation partner announcements, public posts |
| System change | Procore adoption or expansion | A sub newly appears on Procore or adds modules. That's the moment the gap between the project system and the accounting system becomes visible to them | Procore Network profiles, job posts requiring Procore |
| System change | Public complaint about the gap | Someone in the ICP posts the pain themselves, by name, with a date. We saw a construction managing partner do exactly this on 15 July 2026 | Social listening across named accounts and trade forums |
| Community | CFMA chapter activity | The Construction Financial Management Association is your buyer persona already organised into a list. Chapter rosters, chapter events, and who shows up to them | CFMA chapter pages and event listings |
| Community | Association membership by trade | Trade bodies publish member directories, and membership tells you both the trade and the seriousness of the firm | Association member directories, enriched and matched |
| Community | Conference attendee and speaker lists | Who is registered, who is speaking, and who posts about going. Worked as a pre-event and post-event segment on its own clock | Event sites, badge scans, social posts around the dates |
One signal we cut, and why it's worth revisiting. The original proposal led with manufacturer price-increase bulletins, the monthly published lists naming a manufacturer, a percentage and an effective date, per trade. You cut it, so it's not in the fifteen above. It's worth saying out loud that it was the closest match to your product mechanism we found: a dated increase is a dated prediction of when a specific trade's order confirmations stop matching their POs. The commodity and tariff signals in the price pressure layer cover the same ground more broadly and with less precision. If you ever want the sharper version back, it's a build, not a redesign.
Worth knowing before you plan the booth. Billd and Billy, neither of them AP companies, both publish guides aimed at subcontractor finance leaders timed to CFMA. That room is already being worked by vendors with more budget than you. The counter is not to outspend them at the event. It is to arrive with a sequence that started weeks earlier, so the badge scan is a second touch rather than a first.
One more, and it's slightly awkward. Your homepage cites a Vergo subcontractor AP guide as the benchmark source for the 25-minute-per-invoice figure. Vergo is a direct competitor with roughly $9M raised. Citing them is honest and we'd never suggest hiding a source, but you're currently sending your own prospects a reason to go and read a competitor's content. Worth finding a neutral source for that number.
Three answers change the work. What the Procore integration actually does, whether Sage 300 CRE or Vista is on the roadmap, and whether there is a single customer whose result you can put in an email. None of them is a blocker for the call. All three are blockers for the first send.
Thirty minutes. We walk through all fifteen signals, the scoring model, the routing rules, and which of them are firing on real subcontractors right now. If it's not a fit we'll say so on the call.
