Ignition covers the commercial side of running a firm rather than the work itself. It builds proposals, turns them into engagement letters and contracts, then bills and collects payment automatically, including WIP billing for time-based work. Core includes bulk proposal sending, single renewals, set-up assistance and custom brochure design, and Pro adds bulk renewals, videos and landing pages in proposals, custom domains and email branding, lead and client forms, and integrations with Zapier, XPM, Karbon and FYI. Pro+ adds proposal reviews and approvals, a deals pipeline and advanced reports. AML and KYC compliance tools are available too. Pricing is by tier rather than per user: Core is $99 a month for 50 active clients and 3 users, and Pro is $229 for 350 clients and 15 users. Ignition has no job workflow, task lists or client document portal comparable to the tools above it, so it ranks lower here as a standalone choice.
Who it is for
Firms that want to automate proposals, engagement letters and payment collection alongside a separate workflow tool.
Price
Core from $99 per month for 50 active clients and 3 users, with a discount for annual billing; Pro from $229.
