On a residential job the general contractor's own employees are a minority of the people on site. If the software only covers them, it covers half the project, and the other half keeps calling and texting. CPro360 gives every subcontractor a free seat, a native app, their tasks and dates, their bids, quotations and invoices, and alerts by SMS and email, in English or Spanish. This page lists what a sub sees and does, what your office does for them, and what is not in the portal yet.
Most construction platforms treat the subcontractor as an afterthought: a paid seat, a web-only login, or a link in an email that opens a read-only page. The result is predictable. Subs do not log in, so the schedule in the software drifts from the schedule in reality, invoices arrive as photos in a text thread, and the project manager is back on the phone within a month.
The fix is not more training. It is removing every reason a sub has not to use it: no cost, a phone app that works in a basement, only the information that concerns them, and a way to bid and invoice that is faster than what they do today.
In the browser portal and the native app.
A dashboard of the projects they are on and the tasks assigned to them with dates, plus the estimated costs for those tasks and the documents you have shared with them. They do not see the project budget, other vendors' bids or other vendors' invoices.
When a task they are on moves, the sub is notified of the new dates. When the 14-day forecast flags a weather-sensitive task of theirs, they get the alert the same morning your project manager does. Each sub chooses email, SMS or both, and SMS respects carrier opt-outs.
When you send a trade bid package, invited subs see it in the portal with the scope of work and plans and enter their bid there. Or they reply to the invitation email with their price, and the reply is captured and turned into a draft bid for you to review. Bids line up side by side against your estimate for leveling, and the winner is awarded straight to a subcontract.
A sub submits a price quotation against an assigned task, and submits and tracks invoices for their work, from the portal or the app, with a photo or PDF attached. On Growth and Pro your side reads the document with AI into line items, and the invoice is approved against the subcontract's schedule of values before it is paid.
Subs see their own subcontracts and the project's communications thread, so questions and answers stay on the project. The app and portal are available in English and Mexican Spanish, chosen per user.

Certificates of insurance and W-9s are uploaded by your office against the vendor record, with AI reading the expiry. Self-service compliance uploads from the sub portal, and sub-side acknowledgement of subcontracts, are on the roadmap. If either is a must-have for you today, raise it on the demo.
No. Subcontractor portal seats are unlimited and free on every plan, Starter included. Invite ten subs or five hundred; the price stays the same. Only your internal users count toward the plan's user limit.
No, but they can. The portal works in a browser, and there is a native iOS and Android app with the same view that caches everything offline and syncs when the phone finds signal. Schedule changes and weather alerts reach them by email and SMS whether or not they open either.
Two ways. In the portal, a sub sees the bid packages they have been invited to, with the scope of work and plans, and enters a bid. Or they simply reply to the invitation email with their pricing; the reply is captured and becomes a draft bid for you to review. Either way the bids line up side by side for leveling against your estimate.
Your office keeps each subcontractor's certificate of insurance and W-9 on their vendor record; the expiry date is read from the uploaded certificate by AI and tracked, with a dashboard of certificates expiring in the next 30 days. When a payment is recorded for a sub whose insurance has lapsed or whose W-9 is missing, the payment is held for admin approval with the reason shown, and held payments stay out of the spend totals until released.
No. A sub sees the tasks assigned to them, the estimated costs for those tasks, the documents shared with them, the project's communications and their own quotations, invoices and subcontracts. They do not see the project budget, other vendors' bids or other vendors' invoices.
Unlimited free sub seats on every plan, from $49 a month. A 30-day trial with no credit card, or a 20-minute demo.
