TaxDome is a full practice-management suite. If you mostly need to send engagement letters, get them e-signed, and keep a sealed record, without per-seat pricing or a weekend of setup, FirmForms does that one job at a flat price.
TaxDome is a genuinely capable platform, and for firms that want an all-in-one system it earns its price. But many solo and micro firms tell the same story: they bought the whole suite to send a letter and collect a signature, then paid per seat, signed an annual contract, and spent real time learning modules they never use. FirmForms is the opposite trade: one focused workflow, flat pricing, and nothing to learn.
| FirmForms | TaxDome | |
|---|---|---|
| Price | $35/mo flat, or $348/yr | From about $66/user/mo, billed annually; more on higher tiers |
| Pricing model | Flat, whole firm included | Per user, annual commitment |
| Engagement letters + e-signature | Yes, the whole focus | Yes, one feature among many |
| Sealed audit-trail certificate | Yes, on every signature | Yes |
| Full practice-management suite (CRM, docs, workflows, portal) | No, by design | Yes |
| Time to your first signed letter | Minutes | A meaningful setup |
| Contract | Cancel anytime | Annual |

you want a full practice-management platform, CRM, document management, workflows, a branded client portal, and firm-wide billing, and you have the time to set it up and roll it out. It does much more than FirmForms.
you are solo or micro, you mostly need engagement letters signed and on file with a court-ready record, and you would rather pay one flat price than per seat for a suite you will only partly use.
FirmForms is a lean alternative to TaxDome for solo tax and bookkeeping firms that mainly need to send engagement letters, get them e-signed, and keep a sealed record. It is $35 per month flat with no per-seat pricing, versus TaxDome's per-user, annual practice-management suite. TaxDome does far more (CRM, document management, workflows, client portal); FirmForms does the engagement-letter workflow at a flat price.
FirmForms is $35 per month flat for the whole firm, or $348 per year. TaxDome is billed per user per year, from roughly $66 per user per month on its entry tier and more on higher tiers. For a solo firm, FirmForms is typically a fraction of the cost, though TaxDome includes a full practice-management platform that FirmForms does not. Verify current pricing on each vendor's site.
Yes. That is the entire point. FirmForms does one job: send an engagement letter, collect a legally valid e-signature, and seal the result into a court-ready PDF with an audit trail. There is no suite to adopt and nothing to migrate.
No, and that is deliberate. FirmForms does not replace a practice-management platform. It has no CRM, no document-management system, and no built-in billing engine. It surfaces your own payment link after signing, but it never processes payments or takes a cut. If you need those systems, TaxDome is the better fit.
TaxDome is the better choice if you want an all-in-one practice-management platform (CRM, document management, workflows, a client portal, and billing) and have time to set it up. FirmForms is focused only on the engagement-letter workflow.
Free to start, no card. $35/month flat when you are ready, every user included.
