Ignition bundles proposals, engagement letters, billing, and payment collection. If you just want engagement letters signed at a flat price, with no cut taken from your payments and no billing system to adopt, FirmForms does that.
Ignition is a strong proposals-and-billing platform, and for firms that want proposals flowing all the way through to collected payments, it does a lot. But its Solo plan is capped, and every payment it collects carries a processing fee. Many solo firms just want the engagement letter signed and on file, and would rather collect payment through the method they already use. FirmForms is flat, takes no cut of your payments, and does not cap your clients.
