Walk into ten different accountancy practices and you will find ten different collections of software. Some have grown organically over many years, adding tools as needs arose and rarely removing anything. Others have tried to consolidate and ended up with partial integrations that work most of the time. Very few have built their technology with a clear architecture in mind.
That matters more now than it did five years ago. Client expectations have risen. Compliance requirements have become more complex. The economics of delivering compliance-only services are tightening. And AI tools are only valuable if the data and systems they connect to are structured and accessible.
This article sets out what a well-built accountancy firm tech stack should look like, covering the six layers that every practice needs and where each component fits.
Layer 1: Finance and Practice Management
This is the operational core of the practice. It handles the firm's own accounts, billing, time recording, WIP management, project tracking and resource planning. Everything else either feeds into this layer or draws from it.
The right platform here is not a basic accounting tool. It is a full ERP system capable of managing the complexity of a professional services firm: multiple fee earners, varying billing models, project-based engagements, partner drawings and practice-level profitability reporting.
Dynamics 365 Business Central sits at this layer within the EdgeBooks accelerator. It provides the financial rigour and operational depth that a growing practice needs, without the implementation overhead of a bespoke system.
Key capabilities to look for at this layer include integrated time recording with automated capture rather than batch entry; WIP management with real-time visibility by partner, client and engagement; flexible billing workflows covering fixed fee, time-based and milestone models; project and resource management connected to financial outcomes; and practice-level profitability reporting by service line, partner and client.
Layer 2: Client Relationship Management
The CRM layer is where your practice manages everything related to client and prospect relationships: contact records, communication history, opportunity pipelines, proposals sent, referral sources and cross-sell activity.
Many practices still manage this through shared inboxes, spreadsheets or the memory of individual partners. This creates a fragile, partner-dependent model that limits growth and creates risk when people leave.
A properly configured CRM, connected to the finance and practice management layer, gives the whole firm a single view of every relationship. Within EdgeBooks, Dynamics 365 Customer Engagement provides this capability, with workflows configured for how accountancy practices actually develop and manage client relationships.
Layer 3: Document Management and Collaboration
Accountancy firms generate and handle large volumes of documents: client correspondence, engagement letters, working papers, statutory accounts, tax returns, board packs. These need to be stored securely, version-controlled, accessible to the right people and retrievable quickly.
Microsoft SharePoint, as part of the Microsoft 365 suite, handles this within a security framework that meets the requirements of a professional services environment. Because it sits within the same Microsoft ecosystem as Dynamics 365 and Business Central, documents are accessible directly from client records without switching between systems.
Microsoft Teams provides the collaboration layer alongside SharePoint, giving your team a single place for internal communication, client-facing meetings and project collaboration.
Layer 4: Compliance and Deadline Management
Compliance tracking is one of the highest-risk areas in any accountancy practice. Missed deadlines carry financial penalties and reputational consequences. Yet many practices still track their compliance obligations through spreadsheets or the calendar reminders of individual fee earners.
A dedicated compliance management layer, integrated with the practice management system, automates deadline tracking, sends alerts as due dates approach and provides practice leadership with a real-time view of compliance status across the entire client base. Within the EdgeBooks framework, this is configured within Business Central and supplemented by Power Automate workflows that handle notifications and escalations.
Layer 5: Reporting and Business Intelligence
Data that sits inside systems and cannot be surfaced quickly and clearly is of limited value. The reporting layer of your tech stack determines how effectively your practice can use the information it holds.
Power BI, connected to Business Central and Dynamics 365, provides a business intelligence layer that goes well beyond the native reporting in either system. Partners can access dashboards showing their client profitability, utilisation rates and pipeline value in real time. Practice leadership can see firm-wide performance across every dimension. Clients can be given access to their own financial dashboards, which is increasingly a differentiator in advisory relationships.
The reporting layer should be interactive, real-time and accessible without requiring someone to produce a spreadsheet. If your management information is only as current as the last time someone updated a report manually, you are making decisions with incomplete information.
Layer 6: AI and Automation
AI is no longer a future consideration for accountancy firms. It is a present capability that is already available within the Microsoft tools most practices use every day.
Microsoft Copilot, embedded across Microsoft 365 and connected to Dynamics 365 and Business Central, provides AI assistance at every layer of the stack. It drafts client correspondence, summarises documents, analyses financial data in natural language, generates proposals and automates routine compliance communications. Power Automate handles workflow automation across the practice, reducing manual processes and eliminating repetitive tasks.
The effectiveness of the AI layer depends entirely on the quality of the layers beneath it. Copilot working with structured, connected data in Dynamics 365 and Business Central delivers significantly more useful outputs than AI tools working with fragmented information held across disconnected systems.
How EdgeBooks Brings the Stack Together
Building each of these layers separately and connecting them is possible, but it is time-consuming, expensive and requires ongoing maintenance as each component updates. The value of an accelerator like EdgeBooks is that the connections between layers are already built and configured for accountancy firm workflows.
Dynamics 365 Business Central handles layers one and four. Dynamics 365 Customer Engagement handles layer two. Microsoft 365, SharePoint and Teams handle layer three. Power BI handles layer five. Copilot and Power Automate handle layer six. All of it sits within the Microsoft ecosystem and is configured by Advantage to work together from day one.
