AI for construction companies.
Custom integrations built around your existing data.
General contractors, mechanical contractors, electrical, plumbing, and specialty trades — typically 5–50 employees running multiple active job sites with crews, subs, and a constant flow of bids, change orders, and invoices.
What's different about AI for construction companies.
Construction firms drown in paperwork that's structured but never organized: bid packages, RFPs, RFIs, change orders, daily reports, certified payrolls, lien waivers, COI tracking. The information exists — but it lives in PDFs, in Procore, in someone's email, in a clipboard at the job trailer. AI integrations don't replace the work; they make the existing work findable and the routine drafting automatic. A general contractor that integrates Claude into their bid + project workflow gets their PMs out of administrative drowning and back onto the actual job.
The busywork patterns most construction companies firms run on.
Pull from past winning bids, current cost data, and the RFP requirements to draft a first-pass response in 20 minutes instead of 2 days.
Match the change request against the original scope, calculate the cost delta from your assemblies database, draft the CO narrative — the PM only edits.
Crew foreman dictates a 30-second voice note from the site; AI structures it into a daily report formatted for the GC and the owner.
AI cross-references the spec book against received submittals and flags every gap weekly — the project engineer reviews, doesn't author.
COI tracking, W-9 collection, lien waiver chasing — automated reminders + AI-drafted follow-up emails to subs who're behind.
Photos in, items categorized by trade, assigned to the responsible sub, tracked to completion — the super stops being a switchboard.
Concrete examples, not abstract capabilities.
Read-only access to project documents, RFIs, submittals, daily reports — staff query in natural language across the entire project history.
Connect ePlan / Building Connected / past-bid archive into Claude for draft responses, takeoff verification, and competitive-margin analysis.
Foremen call a number, dictate the day; AI structures into the daily report, the safety log, and the equipment usage record.
QuickBooks AP + COI database + lien waiver tracker, all queryable: 'which subs on Project X have expired insurance?' Answered instantly.
Upload the spec book + drawings; field crews ask 'what's the rebar spec for slab on grade?' and get an answer with the page reference.

Don't see your specific software? It's almost certainly integratable. Bring the list to the discovery call and we'll tell you what's possible.
A specific moment, not a marketing claim.
A project manager opens an RFP that landed Friday afternoon, due Tuesday. Instead of starting from scratch, they ask the firm's AI: 'find the 5 most similar bids we've won in the past 18 months and pull what we charged for site work.' Three seconds later: a comparison table with project size, geography, our markup, and the winning competitor's reported number where it's available. The PM has a defensible bid in 90 minutes instead of 14 hours.
Build fee + monthly retainer. Both transparent.
Construction integrations typically run $2,000–$5,000/mo depending on the number of concurrent projects. The ROI math: replacing 20 hours/week of admin drift with 5 hours of AI-assisted review pays for the integration in the first 3 weeks.
We don't mark up API usage. The retainer covers Mainsail's work — building, maintaining, and expanding the integration. You see the actual Anthropic / OpenAI usage in your monthly summary. See the full pricing model →

What does a Mainsail AI integration cost for construction companies?
Construction integrations typically run $2,000–$5,000/mo depending on the number of concurrent projects. The ROI math: replacing 20 hours/week of admin drift with 5 hours of AI-assisted review pays for the integration in the first 3 weeks. The build fee is one-time; the monthly retainer covers AI API usage (passed through at cost), ongoing maintenance, and new use cases as they come up. No long-term contract — month-to-month after the first month.
-
Which construction companies software does Mainsail integrate with?
Most of the systems construction companies already use have APIs that work cleanly with Claude. Common integrations include: Procore / Buildertrend / CoConstruct, QuickBooks (AP, AR, payroll), Bid archive (PDFs, Word, Excel), ePlan / Building Connected, Email (RFI, RFP, change orders), Field photo libraries (job-site documentation). If a tool doesn't have an API but does have data exports (CSV, scheduled reports), we build a slightly different ingestion layer. The only hard 'no' is software that contractually forbids automated access.
-
Is my data safe? What stops the AI from being trained on it?
Anthropic's API doesn't train on data submitted via their business tier — it's contractually excluded. Same for OpenAI's enterprise tier. Mainsail builds integrations that route through these enterprise APIs only. Your data is never used to train the underlying model, never shared between accounts, and lives in your authorized workspace only. We document the data flow in the engagement brief so you know exactly what's accessed.
-
How fast does the first integration ship?
Discovery call → scoping doc → 2–3 weeks of build → live in your team's hands. Most clients see real time savings within the first month. Compounding wins (the team finds new ways to use the assistant, you add more data sources) typically show up in months 2–4.
-
What if I want to start small?
That's how most projects start. Pick the single highest-friction workflow in your business — the thing costing your team the most hours per week — and we build the integration just for that. Usually 2–3 weeks, $1,500–$3,000 one-time, $400–$1,200/mo recurring. If it earns its keep, expand. If it doesn't, you can stop after the first month with no further commitment.
Independent CPA firms, small accounting practices, and bookkeeping shops — typically 1–15 staff serving small-business clients across local industries.
Independent restaurants, small chains (2–8 locations), and food-service operators — typically running on Toast or Square POS with limited back-office staff and zero appetite for software they have to manage themselves.
Solo agents, small teams (2–10 agents), and boutique brokerages — typically running on a CRM (Follow Up Boss, kvCORE, Wise Agent), MLS access, and a constant flow of leads, listings, and transactions across multiple stages.
Independent property management companies serving 50–500 units of residential or small commercial — typically running on Buildium, AppFolio, or Propertyware with a tenant base, an owner base, and a maintenance crew.
