Proposals and retainers for a freelance designer.

Before you build it, four documents about it: who else is already selling to the solo designer sending three proposals a month, one price you can defend, a money model with every guess labelled, and where the first customers are.

What it checks first, for this one.

1. What the proposal tools charge, and how many of them bundle e-signature rather than reselling it
2. Whether the invoicing tool the freelancer already pays for sends proposals too
3. What a signature has to satisfy to be binding in this market, which decides whether this can be built alone

Does a higher win rate on three proposals a month beat a subscription, or does it need six?
