BidForge vs Joist: Which Estimate Tool Is Better for Contractors? (2026)

Joist has been a go-to estimate app for contractors since 2014. BidForge launched in 2026 with an AI-first approach. If you're deciding between the two, here's an honest breakdown of what each does well — and where each falls short.

Quick Summary

  • Joist — Established, mobile-first, great for invoicing + payments. Manual estimate builder with templates. Best for contractors who want an all-in-one business tool.
  • BidForge — AI-powered, fastest time-to-estimate. Describe the job in plain English, get a professional proposal in 60 seconds. Best for contractors who hate paperwork and want speed.

Feature Comparison

Estimate Creation

  • Joist: Manual line-item builder. You add each material, set quantities, prices, markups. Works like a spreadsheet. Time to create: 15-30 minutes for a typical job.
  • BidForge: AI-generated. Describe the job ("800 sqft cedar fence, board-on-board, 2 gates") and get a complete itemized estimate in ~60 seconds. Edit anything you want after.
  • Winner: BidForge (10x faster)

Pricing Accuracy

  • Joist: As accurate as you make it — you enter all prices manually. No built-in price database.
  • BidForge: AI trained on real contractor pricing data. Calibration system lets you input past jobs so it learns your actual rates. Hard-cost validation warns you if estimates seem off.
  • Winner: BidForge (built-in pricing intelligence + calibration)

Invoicing & Payments

  • Joist: Full invoicing suite — convert estimates to invoices, accept credit card payments, track payment status. This is Joist's strongest feature.
  • BidForge: Focused on the estimate/proposal stage. Invoicing coming soon but not the core product today.
  • Winner: Joist (mature invoicing system)

Mobile Experience

  • Joist: Native iOS and Android apps. Built for creating estimates on-site from your phone.
  • BidForge: Mobile-responsive web app. Works on any phone browser. No native app yet, but the AI-first approach means less tapping and typing on mobile.
  • Winner: Joist (native apps), but BidForge is close (less typing needed)

Client Experience

  • Joist: Clean estimate PDFs. Clients can approve online. Professional but generic-looking.
  • BidForge: Professional proposals with scope descriptions, itemized pricing, and branded layout. Designed to look like a $5,000/month firm's output.
  • Winner: BidForge (proposals look more professional)

Pricing

Joist Pricing

  • Free: 3 estimates/month, basic features
  • Pro: $19.99/month — unlimited estimates, custom branding
  • Pro+: $39.99/month — adds online payments, request signatures

BidForge Pricing

  • Free trial: Try it free, no credit card
  • Pro: $29/month — unlimited AI estimates, calibration, price book, all trades

Who Should Use Joist?

  • Contractors who need invoicing + payments in the same app
  • Those who prefer building estimates manually line by line
  • Businesses that want a native mobile app
  • Contractors already on Joist with existing templates and client history

Who Should Use BidForge?

  • Contractors who hate spending 30 minutes on each estimate
  • Solo operators who don't have a dedicated estimator
  • Anyone who loses jobs because they're slow to send proposals
  • Contractors who want AI-powered pricing calibrated to their actual costs
  • Those who want proposals that look more professional than a basic line-item list

The Bottom Line

Joist is a solid all-in-one tool that's been around for a decade. If you need invoicing, payments, and estimates in one app, it's a proven choice.

BidForge is purpose-built for the estimate/proposal stage — the moment that wins or loses the job. If your bottleneck is speed (getting proposals out before competitors) and quality (making your estimates look professional), BidForge does that better and faster than anything else on the market.

Many contractors use both: BidForge to create the estimate fast, then export it to their invoicing tool. They're not mutually exclusive.

See the difference yourself.
