Send your first bid package
Invite trade partners by email, level the bids in one grid, award with an accounting code.
A bid package belongs to a project and a category. You pick the trade partners to invite from Contacts, and each one gets an email with the package. Reminders go out on their own until a bid comes in.
A trade partner can reply to that email with a PDF and never make an account. BuilderLevel reads the number off the PDF and asks you to confirm it. A trade partner who wants more can create a free account, and the same package shows up in their Bids tab.
Bids level in one grid. When you award, you pick an accounting code and the number lands on that line of the budget. The bid PDF files itself into Specs. Awarding also asks whether to notify the trade partner, and your company setting decides the default answer.
