Yes — Corten is estimating and bid software built for subcontractors, not just GCs. Whether you run electrical, mechanical, concrete, or any trade, Corten's AI reads the vendor quotes and material pricing you already receive, auto-fills your bid sheet, and drafts a proposal to the general contractor written from your own numbers. When you win, that same record invoices the GC — no retyping.
Estimating and bid software for subcontractors is a tool that turns a sub's own vendor quotes and pricing into a finished bid and proposal — and Corten does it by having its AI read the documents you already have and auto-fill the bid sheet, so you review numbers instead of keying them.
Reads your vendor quotes
Drop in the material and supplier quotes you already receive and Corten's AI reads each one — vendor, item, scope, and amount — and loads it into your bid worksheet. It works from the quotes and documents you have; it does not measure quantities off drawings.
Your bid sheet, built for a sub
Line items roll up with canonical bid-total math, markup, and profit so your number is right every time. Compare supplier pricing side by side and catch gaps or outliers without a spreadsheet.
Proposals to the GC that draft themselves
When your numbers are set, the proposal drafts itself from your winning line items, with scope written from your vendors' quotes. Send a clean, branded proposal to the general contractor in minutes.
One connected record: bid to invoice
Enter it once and it flows — bid to proposal to budget to invoice. Won estimates convert to jobs, jobs generate invoices to the GC, and approved change orders roll into the budget automatically.
Runs in the field, priced for a small shop
Update tasks, punch lists with photo uploads, daily logs, and RFIs from any phone or tablet, with SMS reminders. Plans are flat and published from $99/month, with AI included on every one — no add-on.
Frequently asked
Does Corten work for subcontractors, or only general contractors?
Both — and Corten is genuinely built for subs, not a GC tool with a sub mode bolted on. As a subcontractor you use it to read your own vendor quotes, build your bid sheet, send proposals to GCs, and invoice from the same record. It fits any trade — electrical, mechanical, concrete, and the rest.
Can Corten read my vendor and supplier quotes?
Yes. Its AI reads the vendor quotes, material pricing, receipts, and invoices you already receive and auto-fills your bid worksheet — vendor, scope, and amount — then rolls it up to your bid sheet. Everything is queued for your review, so you check the work instead of retyping it.
Does Corten do drawing or quantity takeoff?
No. Corten is not a takeoff tool — it does not measure plans, count symbols, or read geometry off drawings. It works downstream of takeoff, reading the vendor quotes and documents you already have to fill your bid sheet and proposal. If you use a takeoff tool, its output is simply one of the inputs Corten works with.
How much does Corten cost for a subcontractor?
Pricing is flat and published: Solo is $99/month for 1 user, Crew is $229/month for 2–8 users, and General Contractor is $449/month for 9–20 users. AI is included on every plan at no extra cost, and there's a 14-day free trial with full AI — during the current beta, signups get 2 months free.
