Additions estimate FAQ

How do I keep sub quotes organized?

Enter each sub quote as a subcontractor item in its section. Your markup applies automatically and the customer sees section totals.

Will my customer see my costs?

No. The proposal shows only customer prices, in the level of detail you choose. Internal costs, markup, margin, and notes never appear.

Do the suggested items include prices?

No. Suggestions help you remember what belongs in the bid. You enter your own costs, so nothing is priced with made-up numbers.
