For UK accountancy and bookkeeping firms

We built our firm on AI.
Now we build yours.

AI operating systems for UK accountancy and bookkeeping firms. We automate repetitive operational work like client email handling, admin and compliance workflows, and bookkeeping review support using systems already proven inside a live practice.

Human-in-the-loop systems. Built by operators. Designed for detail-heavy, regulated work.

Directional Proof From Live Operations

The proof points to operational outcomes, not AI theatre.

These are cautious, internal figures from the practice that shaped our approach. We keep the claims measured until every number is fully documented.

client replies and workflow actions stay under staff oversight where judgement matters

The Problem

If your firm feels operationally heavier than it should, this is usually why.

We focus on the repeatable work that drains capacity inside UK accountancy and bookkeeping firms.

Replies start with a context hunt.

Your team wastes time pulling together prior emails, notes, records, and task history before they can answer a client properly.

Admin depends on memory.

Chasing documents, following up after meetings, and keeping internal tasks moving still relies too heavily on people remembering what comes next.

Client information is fragmented.

The context needed to do good work is spread across inboxes, spreadsheets, practice software, and meeting notes.

Skilled people are stuck in repetitive work.

Qualified staff are still spending time on tasks that follow a repeatable pattern and should be systemised.

Bottlenecks cap growth.

Operational drag slows response times, creates inconsistency, and limits how much work your firm can handle well.

What We Build

Three workflow systems we start with most often

These are concrete, high-friction workflows where firms usually see value fastest.

Client Email Intelligence

When a client email arrives, the system gathers context from your records and drafts a response for your team to approve.

  • Prior emails and notes
  • Client records and task history
  • Human-approved draft replies

AI Admin & Compliance Workflows

Automate onboarding chases, document collection, reminders, meeting follow-up, AML support tasks, and internal routing.

  • Onboarding and document chases
  • Meeting and follow-up workflows

The Process

Start with one workflow. Prove the value. Expand from there.

The buyer journey should feel low-risk and concrete from the first click.

Scorecard

Step 1

Take the AI Readiness Scorecard to see where repetitive work, poor response flow, and operational drag are costing your firm the most.

2

Audit

Step 2

Book an AI Workflow Audit and we map the first high-value workflow worth fixing, along with the systems and handoffs around it.

3

First workflow

Step 3

We implement one supervised workflow, connect it to your existing tools, and prove the value in live operations before anything expands.

4

Scale

Step 4

If the first workflow earns its place, we extend the system into other operational bottlenecks across the firm.

Why SIS

Why firms choose SIS

The positioning is narrow on purpose: real operations, careful automation, and a clear first workflow.

Built inside a real practice.

We run a live accountancy practice on the same kind of systems we build, so the proof comes from real operational pressure rather than theory.

Builder mentality.

We design and build systems around the workflow itself. That means fewer compromises, better fit, and less dependence on generic software workarounds.

Human in the loop.

Judgement stays with your team where it matters. We automate the repetitive work and keep human approval visible in client-facing and risk-sensitive tasks.

Comfortable in regulated work.

Accountancy and bookkeeping firms operate in detail-heavy environments where trust, consistency, and auditability matter. Our systems are designed with that reality in mind.
