Comparison
Three tools. Very different jobs. Here is how to pick the right one for your practice.
TaxDome and Ignition are practice management platforms. They handle invoicing, client portals, task management, scheduling, and a dozen other things your practice might need. If you want one system that runs everything, they are worth evaluating. EngageDraft does none of that. EngageDraft generates a professionally worded, AICPA-aligned engagement letter from a short intake form, and sends it to your client for e-signature in the same session. No template library to manage. No annual license for features you will not use. If the problem you need to solve is engagement letters, EngageDraft solves it and nothing else. For a breakdown of what every engagement letter should cover, see the engagement letter guide for CPAs.

Use EngageDraft if...
You are a CPA, enrolled agent, or independent tax preparer. You handle engagement letters yourself and want them done fast, done right, and sent the same day you decide to engage a client. You do not need a client portal or project management. You need a compliant letter in front of your client with a signing link attached.
Use TaxDome if...
You are running a growing practice and want one platform to manage clients, tasks, documents, billing, and communication. Engagement letters are one small part of a larger system you want to standardize. You have the time and staff to configure it properly and the client volume to justify the cost.
Use Ignition if...
Your practice is built around retainer relationships and advisory work. You want to combine proposals, engagement terms, and automated billing in one flow. You are less focused on tax prep volume and more focused on scoping ongoing engagements with fee approval built in.
Generate your first engagement letter in under two minutes.
