The whole practice, not a feature

Most small firms juggle a website, a mailbox, a filing tool and a pile of folders. Keelza is all of that, in one login.

One login. One bill. One system that makes a small practice look and run like a big one.

Client management

Your whole client book, managed.

Add any client in a minute. For a company, the details pull straight from Companies House. For a person, it's a couple of fields. Assign them across your team and see every status at a glance.

  • Companies auto-filled from Companies House; individuals in a couple of fields
  • Import your whole book at once
  • Assign clients to specific accountants and reviewers
  • Clear statuses: onboarding, needs info, ready, filed

Filing & sign-off

Filed, checked, signed. Under your account.

Keelza drafts every return from the client's records. Your team reviews, a qualified accountant signs off, and it goes to HMRC under your own agent account. Prepared by anyone on your team; signed only by the people you authorise. Nothing reaches HMRC without a human.

  • MTD quarterly updates, Self Assessment, CT600 and accounts
  • Drafts prepared automatically, with a note on every judgement call
  • Preparer and signer kept separate, by design
  • A full audit trail of who did what
Your brand & presence

A proper website on your own domain, that you edit yourself. Up to 20 clean business email addresses for you and your team. And a branded portal where your clients see exactly what's filed and what's due.

  • A professional website on your own domain, no developer needed
  • Up to 20 business emails[email protected] for the whole team
  • A client portal at customers.yourfirm.co.uk

Never miss a deadline

Nothing slips through.

Every obligation for every client, pulled in automatically and put on one timeline. The system chases the client and your team, so you stop being the one who remembers.

  • Deadlines auto-pulled from Companies House and HMRC
  • Escalating reminders to clients and staff
  • A document vault so records live in one place, for good
  • No more annual "please send us everything again"
Your team, your rules

Why it changes the maths

Serve thousands, not hundreds. Keep the clients everyone else drops.

A practice caps out at a couple of hundred clients per accountant because preparing returns by hand doesn't scale. Automate the preparation, the chasing and the record-keeping, and one accountant can handle 800 to 1,500. The same firm can serve thousands, and profitably keep the small clients that every other practice is shedding before Making Tax Digital.
