Custom AI Bid Tool for Subcontractors
Turn blueprints into builder-ready bids in minutes.
SubKit is a custom AI bid tool built around your pricing, labor, markup, and trade-specific workflow — so you can upload plans, generate estimates, and send professional bids without living in spreadsheets.
The Problem
Manual bidding is costing you time, money, and builder trust.
Small trade contractors lose bids every week — not because their price is wrong, but because their process is slow and their output looks unprofessional.
Blueprints take too long to review
You spend hours on plans before you even start building the estimate.
Pricing lives in messy spreadsheets
Every bid starts from scratch. Old files, wrong rates, and no consistency.
Builders expect fast turnaround
When you're slow to bid, builders move on. Speed wins jobs.
Missed details kill profit
Miscounting fixtures or skipping exclusions costs you on every job.
Every estimate looks different
No standard format means builders can't compare or approve quickly.
You lose bids when you respond late
A builder gets three bids back in 24 hours. Yours comes in on day 4.
The Solution
SubKit gives your trade business a private estimating system.
Instead of forcing your team into generic software, SubKit is set up around your actual prices, your labor logic, your markup, and the way you bid. It's not a tool you have to learn — it's a tool built for how you already work.
Your pricing loaded once
Your rates, labor costs, fixture prices, markup percentages, and bid notes are set up once. Every estimate uses your numbers — not someone else's defaults.
Blueprints scanned into bid inputs
Upload plan PDFs. SubKit helps identify fixture counts, scope items, and bid inputs so you spend less time reading and more time reviewing.
Professional estimates sent to builders
Once you review and approve, a clean branded estimate goes to the builder by email — formatted professionally and ready to act on.
Process
From plan upload to polished bid in 4 steps.
