Accounting: Practice Management & Cloud Migration

    We modernise accounting practice systems so you can manage clients, deadlines, and compliance in one place.

    Systems we commonly modernise in accounting.

    Every practice has its own stack, cobbled together over the years as the firm grew and HMRC kept changing the rules. These are the systems we see most often.

    Practice management platforms

    Bespoke Access or VB6 databases, heavily customised IRIS installs, aging CCH/Digita setups that no longer receive meaningful updates.

    Client relationship & engagement

    Client relationship databases and engagement letter management, often spread across multiple tools and shared drives.

    WIP, time recording & billing

    Time recording, work-in-progress tracking, and billing systems — frequently disconnected from client records and fee estimates.

    Tax workflow & deadline management

    SA, CT, VAT, MTD compliance — often held together with Outlook reminders, shared spreadsheets, and a partner's memory.

    Audit scheduling & file management

    Audit planning, scheduling, and audit file management tools that rarely talk to the rest of the practice systems.

    Document management

    Client correspondence, accounts, and tax computations — still sitting on a file server in many practices.

    Client portal & secure exchange

    Branded client portals for secure document exchange — or, in many practices, the absence of one and a reliance on email attachments.

    AML/KYC onboarding & compliance

    Client onboarding, AML/KYC checking, and compliance tools — usually a separate workflow rather than part of engagement.

    Integrations & bureau systems

    Payroll bureau systems and integration layers between practice management, accounts production (Sage, Xero, QuickBooks), HMRC APIs, and Companies House.

    Common problems we see in accounting firms.

    These come up in most conversations with partners and finance leads. You will recognise at least a few.

    Does any of this sound familiar?

    Issue 01

    Client data is everywhere and nowhere

    Engagement letters in one system, time records in another, accounts in a third, tax computations on a shared drive. Every time a partner needs the full picture on a client, someone has to pull information from four different places. A task that should take thirty seconds takes ten minutes, and the answer is never quite complete.

    Issue 02

    Deadlines are missed because tracking is manual

    SA filing deadlines, CT600 due dates, VAT returns, audit schedules, Companies House confirmations — tracked in a spreadsheet, in someone's Outlook calendar, or in their head. One person goes on holiday and a deadline gets missed. The penalty comes out of your fee.

    Issue 03

    More time goes on admin than on client work

    Manual data entry between systems, re-keying client details that already exist somewhere else, chasing staff for timesheets on a Friday afternoon, generating fee notes by hand in Word. Billable hours are being consumed by administration that a connected system would handle automatically.

    Issue 04

    Xero PM, Karbon or Senta don't fit

    Off-the-shelf platforms work well for some firms. But if your practice has particular client onboarding steps, bespoke compliance checks, or billing structures that grew up with the firm, you end up paying a subscription and then running workarounds on top of it. Within six months, the spreadsheets are back.

    Issue 05

    A 15-year-old client database that can't be lost

    Client records, engagement histories, fee analysis, compliance logs, partner notes — this is the institutional knowledge of your practice. It is not in anyone's head; it is in the system. Any modernisation has to bring it all across, intact, with nothing lost in translation.

    Issue 06

    MTD and regulatory changes keep breaking systems

    Making Tax Digital, new HMRC APIs, updated AML regulations, iXBRL requirements. Every regulatory change means another bolt-on, another bridging tool, another manual step in a process that was supposed to be automatic. The cost of keeping up is growing every year.

    How we approach accounting practice modernisation.

    This is a summary. The full process is described on our modernisation and how-we-work pages; here, we want to show you that the approach is designed around how accounting practices operate.

    Before we write a line of code, we map your client records, engagement histories, fee structures, compliance logs, and correspondence. Where documentation does not exist, we reverse-engineer the data model from what is in the system. The goal is a complete inventory of what must be preserved, so there are no surprises during migration.

    Your data comes first

    What a modernised accounting system can support.

    A connected foundation for client management, deadlines, billing, compliance, and secure document exchange.

    Unified client management

    Single view of every client: engagement status, deadlines, WIP, correspondence, compliance history, and fees. Onboarding with AML/KYC built into the workflow, and engagement letter generation tracked automatically.

    Automated deadline tracking

    All regulatory deadlines (SA, CT, VAT, Companies House, audit) tracked across the practice with a RAG-status dashboard for partners and managers. Alerts and escalation before anything is overdue, not after.

    Real-time WIP and billing

    Time recording integrated with client records and fee estimates. Live WIP visibility for partners — know what is billable before month-end, not after. Fee notes and invoicing generated from system data, no re-keying.

    MTD-ready and regulation-proof

    Built-in HMRC API integration for Making Tax Digital (ITSA, VAT, CT). Architecture designed to absorb regulatory changes without bolt-on workarounds. iXBRL submission, Companies House API, and AML reporting built in.

    Secure client portal

    Clients upload documents and approve accounts through a branded portal. No more email attachments with sensitive financial data. Full audit trail for every document exchange.

    Out-of-the-box foundation

    Every modernised system includes internationalisation (i18n), responsive design, CI/CD pipeline, authentication, test data framework, and a demo environment from day one.

    Frequently asked questions

    Can you modernise our systems during busy season?
    We plan around the practice calendar. In most cases, we work in parallel with your existing systems and roll out changes during quieter periods. If a switchover is needed, we agree the timing well in advance. We will not disrupt live client work without your explicit agreement, and we will not run a cutover in January.
    Our client database has 15 years of records. Can you migrate all of it?
    Yes. Client data is the most valuable asset in a practice's technology estate. We extract and migrate client records, engagement histories, fee analysis, compliance logs, and correspondence systematically. We verify the migrated data against the original before anything goes live.
    We've looked at Xero Practice Manager, Karbon or Senta. How is this different?
    Those platforms are designed for a broad market, and if they fit your workflows they are a sensible choice. Where they struggle is with practices that have specific compliance processes, unusual billing structures, or onboarding steps that have evolved with the firm. A modernised bespoke system is built around your workflows rather than someone else's idea of what a practice should look like — and it costs less to adapt over time because you own it.
    How long does a typical accounting practice modernisation take?
    A single-module project (deadline tracking, WIP, or client portal) typically takes 2–4 months. A broader programme covering practice management, workflow automation, and client portal runs 4–8 months. You will see working software within the first few weeks, not at the end of the project.
    How much does it cost?
    Typical accounting practice modernisation projects range from £30K to £150K depending on scope and complexity. Compare that with the combined annual licensing, customisation, and integration costs of commercial platforms over five years, and the numbers are often similar or lower. Book a free call and we will give you a realistic range based on what you describe.
    Will it integrate with HMRC, Sage, and Xero?
    Yes. HMRC API integration (MTD for ITSA, VAT, CT) is built in. Sage, Xero, and QuickBooks integrations are standard. Companies House filing, iXBRL submission, and payroll integrations are all supported.
    What about data security and GDPR?
    Financial client data requires the highest level of care. All modernised systems include encryption at rest and in transit, role-based access control, audit logging, and GDPR-compliant data handling. We can also support Cyber Essentials and ISO 27001 requirements if your practice needs them.

    Named legacy systems we help accounting practices modernise.

    Most accounting practice estates we assess have at least one ageing finance platform behind the visible practice-management layer. These are the named systems we cover most often.
