Why not just use a full practice suite?

Need a suite with timesheets, resourcing, billing runs and a per-user licence? Buy one. Need this week's proposal priced right, sent under your name and kept with the client, and the reference written properly when the engagement ends, for one firm? That is the product.

For the record, on the firm's side: Sowbird supplies no constant of its own; the letter's length and the proposal's total are arithmetic on the engagement facts you enter, by the method printed under each figure. Sowbird Pro is $79 per month for your whole firm.
