Can I invite subs to bid?
Yes. You can invite subcontractors to a bid room — including from CMDBLD’s built-in contractor network — and compare their numbers.
What happens after I win?
The winning estimate becomes a branded proposal, which converts to an e-signable contract with a certified signing audit trail.
Is e-signature included?
Yes. E-signature with a tamper-evident certificate is part of the platform, not a separate service.
