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. For bookkeeping retainer engagements specifically, see the bookkeeping engagement letter guide.

Use EngageDraft if...
Engagement letters are taking longer than they should. You are opening a Word document from last year, doing find-and-replace on the client name, saving it as a PDF, emailing it, and waiting a week for a signature that comes back as a blurry scan. You do not need a practice management platform. You need a compliant letter drafted, sent, and signed without the template hunt, the PDF email chain, and the follow-up. If you are a tax practitioner — including enrolled agents — handling your own engagement letters and you want them done the same day you decide to take on a client, EngageDraft is built for that.
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.
Practitioners leave Ignition for two reasons. First, Ignition pricing scales with client volume, which works for large advisory practices but adds up quickly for a practitioner managing a defined client roster. Second, Ignition uses a proposal format — a document that combines engagement terms with fee approval. That format makes sense for advisory and retainer sales. It does not produce the standalone engagement letter that AICPA standards and Circular 230 call for.
If you are using Ignition primarily to send engagement letters and collect signatures, EngageDraft does that job for a flat monthly rate. It generates AICPA-aligned letter language from a short intake form and does not require you to build proposal templates or configure billing automation you do not need.
The right tool depends on what you need it to do. If you want a full practice management platform that handles billing, task management, and client communication alongside engagement letters, TaxDome or Ignition are worth evaluating. If engagement letters are the specific problem you are solving, EngageDraft generates AICPA-aligned letters from a short intake form and sends them for e-signature in the same session. No template library to manage, no annual license for features you will not use.
For engagement letters specifically, yes. EngageDraft generates professionally worded engagement letters and sends them for e-signature. TaxDome is a full practice management platform that includes engagement letters as one feature among many. If you need practice management, EngageDraft is not a replacement for TaxDome. If engagement letters are the problem you are solving, EngageDraft is a faster and less expensive way to solve it.
Practice Ignition uses a proposal format that combines engagement terms with fee approval in one document. EngageDraft generates standalone engagement letters designed around AICPA guidelines and Circular 230 standards. If your practice requires the formal scope and liability language that engagement letter standards call for rather than a proposal format, EngageDraft is the more appropriate tool.
