• Practice manager spending Monday morning checking a spreadsheet, a shared calendar, and the job management system separately to understand what is due this week and who is responsible for it?

  • Clients calling to ask whether their tax return has been filed yet because the firm has no client-facing portal and the only update mechanism is an email from the manager?

Accounting Practice Management Software Development

Karbon, Senta, and TaxDome work well for practices with standard client types and straightforward compliance workflows. Custom software is the right choice when your client mix, your entity structures, or your internal workflow diverge from what those platforms can model without manual workarounds.

We build practice management systems for accounting firms -- the client database, the engagement tracker, the compliance workflow calendar, the time recording module, the billing system, and the client portal -- all connected and built around the way your firm actually works.

  • Client management covering all entities, contacts, and relationship history for each client in one record

  • Engagement tracking from proposal through delivery with task assignment, due dates, and status visibility

  • Compliance workflow for tax returns, VAT filings, accounts preparation, and confirmation statements with automatic due date calculation

  • Billing with WIP management, time recording, and fee invoice generation integrated with the engagement record

RaftLabs builds custom practice management software for accounting firms -- client and engagement management, compliance workflow for tax returns, VAT filings, and accounts preparation, time recording, billing with WIP management, and a secure client document portal. Most accounting practice management projects deliver in 10 to 14 weeks at a fixed, agreed cost.

When off-the-shelf practice management stops fitting the firm

Karbon and Senta are well-designed products for firms with a standard client base and a predictable compliance workflow. They handle recurring compliance jobs, basic client management, and email integration well. The limit appears when the firm's structure diverges from the platform's assumptions -- a firm with a mix of personal tax, corporate tax, bookkeeping, and advisory work that needs different workflow templates, different fee arrangements, and different client communication patterns for each service line. A firm that manages a complex client group with multiple entities across each client, each with different filing obligations and different year ends. A firm that has grown through acquisition and needs to consolidate client data from two or three different systems into a single view.

We have built practice management systems for sole practitioners and for firms with forty staff. We understand the data model -- the client hierarchy with the beneficial owner at the top, the entities below, and the individuals associated with each -- and we understand the workflow -- the recurring compliance calendar, the job assignment model, the WIP and billing cycle, and the client document exchange.

What we build

Client and entity management

Client record covering all entities associated with the client -- the individual, the companies they direct or own, the trusts they are involved with, and the partnerships they are party to -- in a single client view with every entity's filing obligations, year ends, and engagement status visible without navigating separate records. Contact management linking the individuals who communicate with the firm to the entities they represent, with communication history, preference notes, and relationship strength recorded against the contact. Client onboarding workflow from prospect through AML checks, engagement letter acceptance, and active client status, with each step tracked and the responsible team member assigned. AML and KYC documentation recorded against the client with renewal dates tracked and alerts generated when documentation is approaching expiry. Client group reporting showing all entities across the group, their current engagement status, and any outstanding items so the relationship partner has a full group picture without pulling multiple records.

Engagement and job tracking

Engagement record for each service provided to each entity -- the service type, the fee arrangement, the responsible manager and partner, the start date, the expected delivery date, and the current status. Job creation from the engagement record when work is due, with the job carrying the client context, the job template for that service type, and the deadline calculated from the entity's year end or the statutory due date. Job status tracking through defined stages -- information gathering, preparation, review, client approval, and submission -- with each stage assigned to the responsible team member and the overall job status visible on the manager's dashboard. Overdue job alerts escalating to the manager when a job passes its expected completion date without reaching the next stage. Pipeline view showing all jobs across the practice by status, due date, service type, and responsible team member so the practice manager can spot bottlenecks before they become deadline risks.

Compliance workflow calendar

Automatic due date calculation for every compliance obligation -- the corporation tax filing deadline calculated from the company's year end, the personal tax deadline from the statutory date, the VAT return deadline from the VAT period end, the confirmation statement deadline from the company's incorporation date. Recurring job generation creating the next job for each compliance obligation automatically when the current one is completed, so no obligation is missed because no one remembered to create the job. Compliance calendar view showing all due obligations across the practice for the next 30, 60, and 90 days, filterable by service type, responsible team member, or client group. Deadline alert system notifying the responsible team member and manager when a deadline is approaching with the job not yet at the required stage. Filing confirmation recording when each statutory submission is made, by whom, and with the reference number or acknowledgement from the filing platform, stored against the job for future reference.

Time recording

Time recording against the job and the client from the desktop interface and a mobile app, with the job and client selectable in two taps so recording does not become a reason to skip entries. Timesheet submission and approval -- the team member submits their week's timesheet, the manager reviews and approves, and the approved time is available for WIP reporting and billing without re-entry. WIP dashboard showing unbilled time and cost by client, job, and team member, updated in real time as time is recorded and reviewed rather than waiting for a month-end extract. Chargeable and non-chargeable time distinction with the non-chargeable time allocated to the correct internal category -- business development, training, administration -- so utilisation reporting reflects the real picture. Time budget vs actual by job showing the time estimated at job creation against the time recorded to date, alerting the manager when a job is running over budget before the work is complete.

Billing and WIP management

Fee invoice generation from the job's WIP -- the approved time entries and disbursements assembled into a draft invoice with the narrative pre-populated from the time entry descriptions, edited by the manager before approval and dispatch. Fixed fee billing for engagements where the fee is agreed in advance, with the invoice generated at the billing milestone without needing time entries to drive the amount. Invoice approval workflow routing draft invoices above configured thresholds for partner sign-off before they are sent to the client. Recurring invoice schedules for clients on monthly retainers or fixed annual fee arrangements, with invoices generated automatically on the defined schedule without manual triggering. Aged WIP reporting showing the value of time recorded but not yet billed by client and age, so the billing review focuses on the oldest and highest-value WIP first. Integration with accounting software -- invoices posted to the practice's accounting system without re-entry, and payments received updated in the practice management system when the client pays.

Client document portal

Secure client portal where clients log in to see all documents shared with them -- draft accounts awaiting approval, tax returns awaiting signature, correspondence, and completed filings -- without requiring the client to use email or a shared drive. Document request management allowing the team member to send the client a structured list of the information needed for the current job, with the client uploading documents directly to the request and the team member notified when each item is received. Digital approval workflow for documents requiring client sign-off -- the client reviews the document in the portal and approves digitally with a date and IP record, replacing the process of emailing a PDF, waiting for a scan, and filing the returned document. Deadline communication showing the client their outstanding obligations and the expected completion dates for current jobs, reducing the inbound calls asking for an update. Notification system alerting clients when new documents are available in the portal, when an approval is required, or when a document request has been sent.

Frequently asked questions

Standard platforms handle recurring compliance jobs and basic client management well. Custom is right when your client mix requires different workflow templates and fee arrangements for each service line that the platform can't support, when you manage complex client groups with multiple entities per client and the platform's client model is too flat, when you need the practice management system to integrate tightly with a custom accounting system, or when you have specific AML and KYC workflow requirements the platform doesn't cover. We will tell you honestly if a configured standard platform would cover the requirement.

Yes. We build integrations with HMRC's Making Tax Digital APIs for VAT return submission and with HMRC's agent services for self-assessment and corporation tax filing status. Companies House integration covers confirmation statement filing status and company information retrieval. For statutory accounts filing, we integrate with the iXBRL tagging and submission workflow. The integrations are scoped during discovery to confirm the specific filing types you need to connect.

Data migration starts with an audit of your current system's data -- client records, engagement history, time recording, and billing history. We build a migration script that transforms your current data into the new system's structure and run it in a test environment first so you can validate the output before it goes live. Where your current data is in a format we can extract -- a database, an API export, or a structured file -- we migrate it fully. Where data is in an unstructured format, we agree the migration scope with you during discovery.

A focused build covering client management, engagement tracking, compliance workflow, and time recording typically runs $30,000 to $65,000 depending on the number of service lines and the complexity of the compliance calendar. Adding billing with WIP management, a client document portal, AML workflow, and accounting system integration typically brings the total to $65,000 to $120,000. Fixed cost agreed before development starts, no hourly billing.
