Improving Document Management in an Accounting Firm

Improving document management in an accounting firm is not achieved by purchasing a single platform. It requires creating a consistent information architecture that defines where documents belong, how they are named, who can access them, how staff collaborate, how clients share information, how documents move through workflows, how versions are controlled, how information is retained and how sensitive documents are protected.

Technology helps, but document management is fundamentally a combination of information architecture, governance, workflow, security and people. Before choosing software, a firm should understand how information actually flows through the practice — and design a structure that mirrors the business.

The objective is not simply to move everything to SharePoint. The objective is to create an information environment where documents are easy to find, appropriately protected, consistently structured, easy to collaborate on, governed, connected to business workflows and ready for future automation and AI.

Document management problems rarely appear overnight. They accumulate gradually as a practice takes on more clients, more staff, more specialist systems and more collaboration across offices and remote locations.

Systems that worked acceptably for five people may become difficult to manage at 30, 50 or 100 staff. The number of documents grows, the number of locations where they are stored multiplies and the consistency of how they are organised decreases.

When firm leaders say they want to improve document management, they are usually trying to achieve one or more of these business outcomes:

Before migrating files or purchasing a new platform, a firm should define how information is structured. This means understanding the dimensions that matter to the practice:

LOOKUP Perspective

Good information architecture mirrors the business. Technology should support that structure rather than force the practice into an arbitrary filing model.

Many accounting firms already own Microsoft 365, which includes capabilities that can contribute to document management: SharePoint for document libraries and collaboration, OneDrive for personal files, Teams for communication and file sharing, Microsoft Search for finding information across the environment, Microsoft Purview for information protection and governance, and Power Automate for workflow automation.

However, not every Microsoft 365 feature is available in every licence tier, and SharePoint should not be viewed as a replacement for specialist practice management, tax software or accounting platforms. SharePoint may provide a useful governed collaboration and document layer where appropriate, but the firm's specialist systems remain the authoritative source for specific accounting workflows.

LOOKUP Perspective

Before buying another document platform, understand whether your existing Microsoft 365 environment can appropriately support the requirement. Many firms already own capabilities they are not using effectively.

A common mistake is simply copying shared-drive folders into SharePoint without redesigning the information architecture. This approach migrates existing disorder into a modern platform without addressing the underlying problems.

Properly designed SharePoint document management involves planning:

Permissions are not a set-and-forget configuration. As staff join, change roles and leave, access accumulates over time. Without regular reviews, more people may have access to sensitive client information than the firm intends.

Effective permission governance involves least privilege, role-based access, structured joiner-mover-leaver processes, controlled guest and external sharing, and regular access reviews. For more detailed guidance on protecting client information, see our Protecting Client Information in an Accounting Firm guide.

Documents move through a lifecycle in every accounting practice. Understanding that lifecycle is essential to designing a document environment that supports rather than hinders the work.

Document Lifecycle

Documents move through a lifecycle from request to disposal. Human review, governance and security span the entire journey — not just individual steps.

One of the most common document management problems in accounting firms is uncertainty over which version of a document is current. Emailed attachments, local copies and shared-drive versions create conflicting files that staff may unknowingly work from.

Modern document platforms support co-authoring, version history and controlled review — but these capabilities only help if staff are trained to use them and the firm has adopted consistent practices.

How a firm shares documents with clients affects both security and client experience. Some clients prefer a client portal, others are comfortable with secure links, and some still expect email attachments. The firm's risk profile, client requirements and systems should determine the model — not a single approach applied to every client.

Not all documents require the same level of protection. A practical classification model helps staff understand how to handle different types of information. Common categories include public, internal, confidential and highly sensitive — but classification models should be tailored to the firm's actual information requirements, not adopted generically.

Microsoft Purview sensitivity labels can support classification, labelling and protection of documents, emails and other information. Capabilities depend on configuration and licensing. Retention policies, data loss prevention and audit capability may also contribute to information governance where appropriate.

AI systems such as Microsoft 365 Copilot operate over information the user already has permission to access within supported environments. Poor permissions, naming, structure, information quality and governance can reduce the usefulness of AI and increase oversharing risk.

AI makes information easier to discover. That makes good information governance more important, not less. Before broad AI adoption, firms should understand where sensitive information resides, who can access it, how it is shared, whether permissions are excessive and which AI tools staff are using.

Migration is an opportunity to improve information management, not merely relocate existing disorder. A well-planned migration should include discovery, data clean-up, duplicate review, access review, information architecture design, naming, ownership assignment, a pilot, staff communication, training and validation.

The simplistic approach of copying files from an old drive to SharePoint without any redesign simply moves the problem to a new location. The firm gains a modern platform but retains the same unstructured, hard-to-search, overly permissive information environment.

LOOKUP Perspective

A migration is an opportunity to improve information management, not merely relocate existing disorder. Invest in the design phase before moving a single file.
