Ignition

Who it's for

Ignition is listed as a fit for solo practitioners, small firms and mid-size firms, and the vendor names solo practitioners, small CPA firms, bookkeeping practices and tax offices on its own site. The job it gets hired for: pricing the engagement, getting the letter signed and the first invoice paid before the work starts.

What it costs

Ignition starts at $39/mo (Solo, annual billing; $49 monthly), per month flat by active clients. There is a free trial.

Good to know

Ignition turns a signed proposal into the engagement letter, the payment authorization and the recurring bill in one flow, which is why so many firms use it to end chasing invoices; it connects to QuickBooks Online, Xero, Karbon, TaxDome, Canopy, Financial Cents, ProConnect, UltraTax and CCH Axcess. US prices are posted: Solo $39/mo on annual billing ($49 monthly) for solopreneurs with up to 20 active clients, Core $99 ($149 monthly) for 50 clients and three users, Pro $229 and Pro+ $399, with Enterprise by sales, plus transaction fees when you collect through Ignition and a 14-day trial with no card and zero fees on the first $10,000 collected. AI Price Insights benchmarks your prices and suggests one with its reasoning (an annual add-on; included on Enterprise), AI drafts service descriptions, and the Ignition MCP opens the data to Claude and ChatGPT.
