Ignition

Proposals, engagement letters, and automated billing for accounting firms.

Overview

Ignition handles the front end of every client engagement. 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. Ignition runs a referral program for existing users; a formal affiliate or reseller program with published commission terms was not confirmed at the time of this record.
