Our Pick

Client Communication

Proposals, engagement letters, and payment collection in one streamlined tool.

Overview

Ignition (formerly Practice Ignition) solves one of the most frustrating parts of running an accounting firm: the gap between agreeing work with a client and actually getting paid. It combines proposals, engagement letters, and automatic payment collection in a single workflow.

A client receives a professional proposal, reviews the scope, signs the engagement letter, and sets up a direct debit — all in one flow. When the work starts, Ignition automatically collects payment on the agreed schedule. No chasing invoices, no awkward payment conversations.

The impact on cash flow is typically dramatic. Firms using Ignition report getting paid 30-40 days faster on average.
