Now in early access for tax and accounting firms
Run your tax practice without the price shock.
We're building a simpler, fairly priced home for your firm: client portal, e-signatures with identity checks, billing, workflows and booking in one place. If your current software just got more expensive or harder to use, we built this for you.
No sign-up to try it. The demo is a made-up firm with made-up clients.

Why we're building it
Firms told us the same things: prices keep climbing, simple jobs take too many clicks, and clients get lost. So we started over with those three in mind.
Pricing you can plan around
A flat monthly price by team size, with unlimited clients and e-signatures. Identity checks from prepaid packs, only when you want them. No surprise jump at renewal.
Built for tax season
Returns move through stages, clients get nudged automatically, and your team sees what's stuck before it's late.
Clients do their part on their phone
Upload, sign, approve and pay from one simple to-do list. No app to install, no password to forget.
What's working today
Every screen below is from the live demo. Open it and click around.
A client portal people actually use
Your brand, your clients' to-do list: documents to upload, forms to sign, invoices to pay. Each one checks itself off.

E-sign the 8879 with an identity check
Clients read the form right in the app, pass a quick identity check and sign. You get a signed copy with a full audit trail.

File finished returns in one drop
Drop the PDFs your tax software prints. Each one is matched to its client, named neatly and sent for approval or signature.

Every return on one board
Move work through your own stages. Each stage can send a checklist, an organizer, an invoice or a task for you.

Worried about rebuilding your workflows? Just describe them.
Write how a job goes at your firm in plain English, and ER Tax 360 builds the stages and what each one does: document checklists, e-signatures, client approvals, invoices and messages. You check every stage before it saves. Ask your own Claude or ChatGPT once you connect it, or use the built-in assistant.
In the demo, the built-in assistant is a simple stand-in that works on sample data. Try it under Firm setup, then Stages and automations.

The whole client in one place
Documents, messages, signatures, invoices, meetings and history for each client, with roles so everyone sees only what they should.
