Questions

The honest answers

Not on the list? Email kolbey@coolbid.app and we'll get back to you.

What if my description is messy?
That's the point. Type it like you'd text your helper. coolbid handles typos, HVAC shorthand, and missing details — and asks for clarification in the proposal when it needs to.
Can I attach photos or a supplier quote?
Yes. Attach photos of the existing unit, a supplier line-item PDF, or a marked-up plan. coolbid uses them alongside your description.
How does pricing work?
You start with a small ballpark catalog you own and edit. coolbid maps each BOM line to your catalog at your margin. Override a price and it remembers.
Does it handle labor?
Yes. Claude estimates hours per task category — install, electrical, startup, and so on — using your shop rate from settings.
Who built this?
