Project & estimating software built for small GC firms
Run bids, subs, change orders and draws for every project from one app — with AI that drafts your estimates and a client portal that answers “how’s my project going?” before the call. Estimating and invoicing from $39/month; change orders and the client portal start on Pro, subcontractor tools on Business. 0% platform fee on payments.
Built around how general contractors actually work
Bids across five trades
A kitchen-and-addition bid means pricing demo, framing, electrical, plumbing and finish in one proposal. The AI drafts the full line-item scope from a plain-English description; you tune numbers per sub and send a three-tier quote.
Change orders eat your margin
Scope creep is where GC profit dies. Every “small change” becomes a priced change order the client approves in the portal — documented, invoiced, never absorbed. (Client portal and change orders are included from the Pro plan.)
“How’s my project going?”
The client portal shows progress photos, schedule, approved changes and invoices — so homeowners stop calling for updates and start approving payments faster.
Everything between “can you quote this?” and “paid”
Win the job, protect the margin
- AI estimates covering all trades in one scope — demo to punch list
- Three-tier proposals with allowances the client can choose between
- Change orders priced, client-approved and added to the final invoice (Pro plan and up)
- Progress invoicing (deposit / draws / final) with online payment, 0% platform fee
Run the site & the subs
- Schedule, tasks and daily logs per project — photo-documented (Pro plan and up)
- Subcontractor management (Business plan) with RFIs, submittals and punch lists (Pro and up)
- GPS time tracking with geofenced sites for your own crews
- Client portal: photos, schedule, approvals and payments in one link (Pro plan and up)
Five trades, one schedule, no phone tree
Demo, framing, rough-ins and finish on one timeline, with the sub for each phase and the milestone that triggers the next draw. When the tile slips a week, general contractors drag the phase and the portal shows the homeowner the new dates — no text thread.

What’s the best project management software for a small GC?+
A small general-contracting firm needs estimating, change orders, scheduling, client communication and progress invoicing in one place — priced per plan with per-seat add-ons. FieldsHub covers that from $39/month with a 0% platform fee on payments. Large commercial GCs with dedicated PMs and complex stakeholder chains are usually better served by enterprise platforms like Procore — see our honest comparison. (Client portal and change orders are included from the Pro plan.)
Can it handle progress billing and draws?+
Yes — invoice a deposit at signing, draws at milestones, and the final on completion, all from the original estimate. Customers pay online by card or ACH, and automatic reminders follow up on open balances. FieldsHub does not do retainage or AIA-style schedule-of-values billing yet — use deposits, milestone draws and a payment schedule instead.
Does it replace my spreadsheet-and-texts system?+
That’s exactly what it’s for: estimates, schedules, change orders, sub coordination, photos and payments that currently live across Excel, texts and a shoebox of receipts move into one app your whole crew can use from day one.
Calculator figures are ballpark ranges from national averages — real jobs vary by region, access and scope. See how FieldsHub compares to other tools on the comparisons page.
