Ignition
Proposals, engagement letters, and automated billing for accounting firms.
Overview
Picture a new client engagement: you draft a proposal, attach the engagement letter, set payment terms, and send everything in one link. The client reads, signs, and pays in a single session. That is the Ignition workflow for solo and small to mid-sized accounting firms. You build a proposal, set pricing, include your terms and engagement letter, and send it to the client with one link. The client reads, signs, and pays in a single session. Once signed, Ignition automatically raises invoices and collects payment on the schedule you specified, with no manual billing step required.
The platform works with QuickBooks, Xero, Sage, MYOB, and Xero Practice Manager on the accounting side, and with Karbon, Financial Cents, CCH Axcess, UltraTax CS, TaxDome, and several other practice management tools. Stripe processes card payments. Zapier extends the list further. When a proposal is accepted, downstream systems can be triggered automatically: jobs created in Karbon, projects in Asana, contacts in HubSpot.
Ignition includes an AI Price Insights feature on upper tiers that benchmarks your fees against anonymised industry data to help inform pricing decisions. An optional Deals Pipeline add-on tracks prospects before a proposal is sent. An Online Forms add-on qualifies new enquiries at the top of the funnel.
A 14-day free trial is available with no credit card required.

Pros and Cons
Pros
- Solo and small firms that send recurring proposals and want signed engagement letters tied to billing.
- Practices on Karbon, Financial Cents, CCH Axcess, UltraTax CS, or TaxDome that want proposal-to-billing automation.
- Firms that want billing collected automatically once the engagement letter is signed.
Cons
- Firms that need a permanent free tier. Ignition offers only a 14-day trial.
- Solo practitioners with one-off engagements. Recurring billing is where Ignition pays back.
