One dataset,
instead of five systems

Practice management, time, the ledgers, the portal and the inbox all hold part of the answer. Joined and owned by you, they finally hold the whole one.

The problem

A practice typically runs practice management software, a time system, a portal, a payroll product and a ledger per client. Every one holds a piece of the answer to a simple question, and no one of them holds the answer.

So somebody exports, somebody pastes, and the partner asks for a number that takes two days to produce and is out of date when it arrives.

Joining them is unglamorous and it is the thing that makes everything else possible — the reporting, the automation, and eventually the valuation, because a firm whose numbers are legible is worth more than one whose numbers live in a partner's head.

What we build
01

A technical audit first

What each system will actually give up, in writing, before anybody commits to a build. Some have a clean API. Some have a scheduled export. Some have nothing, and it is better to know that in week one.

02

One owned dataset

Refreshed on a schedule into a database you own, with read-only keys you create and can revoke.

03

Clients matched across systems

The same client under four slightly different names in four systems, reconciled once and kept reconciled.

04

Deadlines in one place

Companies House, HMRC, payroll and your own internal dates, against every client, in one list rather than five.

05

Feeding the rest

Once the data is joined, the reporting and the automation are small builds rather than projects. Most of the cost of both is this step.

06

No rip and replace

Your practice management software stays. We build around it, because the migration you are imagining is worse than the problem.

Proof

Five systems, one answer

Buzz OS joined the practice management, the client records, the deadlines and the comms for Andy's own firm. Everything else — the reporting, the automation, the client portal — was built on top of that one step.

Case study

The practice operating system

Twenty-plus modules, 487 live clients, six AI agents and full HMRC Making Tax Digital filing. Replaced every piece of third-party practice software.

Straight answers

The things people ask.

What if our practice management software has no API?

Then we say so at the audit and price accordingly — usually a scheduled export, occasionally a decision that it is not worth doing. Better to establish that in week one than half way through a build.

How current is the data?

Refreshed on a schedule, typically hourly, rather than streamed live. For a practice that is a distinction without a difference, and it is a great deal cheaper and more reliable.

Is this GDPR-safe?

It stays within your own control: your keys, your database, your retention rules, and a log of everything that touched it. We will put the data-processing position in writing before anything is built.

What happens if we stop working with you?

You keep the code and the data. There is nothing to migrate away from because nothing was rented.
