Why Your ERP User Permissions Deserve More Attention Than They Get

Small and medium-sized businesses across the UK are adopting ERP platforms at a pace that would have seemed unlikely a decade ago. Microsoft Dynamics 365 Business Central has attracted a large and growing user base, many of them companies with fewer than 50 employees. Yet one area consistently falls through the cracks as these organisations scale: controlling who can access, change, or approve what inside the system.

The issue is rarely malicious. A finance assistant who can both create and approve purchase orders. A warehouse manager who retains access to pricing tables long after a role change. These gaps tend to emerge quietly, one permission at a time, until an audit or a costly mistake forces the conversation.

Addressing authorisation risks does not require an enterprise-sized budget. Specialists such as Breda-based software firm 2-Controlware have spent over 17 years building tools specifically for Dynamics environments, making it possible to design, monitor, and enforce user permissions via 2-Controlware without the overhead of a dedicated security team. Solutions at this scale mean smaller organisations no longer have a valid excuse to ignore the problem.

The silent risk inside every growing team

When a business has five employees, everyone does everything. That is survival. But somewhere between ten and thirty staff members, the informal trust model starts to crack in ways that are difficult to spot from the outside.

Picture a scenario familiar to many SMB owners: a bookkeeper is given full admin rights to "keep things simple" during a busy quarter. Months later, those rights remain active because nobody owns the task of reviewing them. The result is a segregation-of-duties conflict that most businesses would not even recognise until an external auditor flags it.

Internal fraud tends to hit smaller organisations harder in relative terms, simply because they lack the layered controls that larger corporations maintain. Weak access controls are regularly cited as one of the most common contributing factors in occupational fraud cases, regardless of industry or geography.

What proper authorisation management actually looks like

Effective access control is not about locking people out. It is about ensuring every user has exactly the permissions their role requires and nothing beyond that. In practice, this means defining roles based on job functions, mapping those roles to specific system capabilities, and reviewing the entire structure on a regular schedule.

Within Business Central, this can become complex quickly. The platform offers granular permission sets, but configuring them manually across dozens of users is tedious and error-prone. That complexity is precisely why dedicated authorisation software has gained traction among mid-market companies, particularly those subject to regulatory requirements around data access and financial controls.

Authorisation tools built for Business Central, such as those offered by 2-Controlware, typically include features like conflict detection, user templates, and continuous monitoring. These capabilities let a finance director or IT manager identify segregation-of-duties violations before they become audit findings. For a company with 30 users spread across finance, procurement, and operations, that kind of automated oversight replaces what would otherwise be hours of manual spreadsheet work each month.

Compliance pressure is reaching smaller organisations too

GDPR enforcement has matured considerably since its introduction in 2018, and the UK's own data protection framework under the Data Protection Act 2018 continues to evolve. UK businesses face real scrutiny over who can access personal data within their systems. The Information Commissioner's Office has demonstrated a willingness to act against organisations of various sizes, not just household names.

Beyond data protection, industries such as manufacturing, distribution, and financial services often face sector-specific requirements around internal controls. SOx compliance, for instance, demands demonstrable segregation of duties with a clear audit trail. Even companies not directly subject to SOx may discover that their larger clients or supply-chain partners require similar standards as a condition of working together.

For UK SMBs running Business Central, authorisation management sits at a practical crossroads. Getting it right reduces the risk of regulatory penalties and simultaneously closes gaps that could lead to financial loss through error or fraud.

Getting started without a dedicated IT department

Many small businesses lack a full-time IT manager, let alone a security specialist. That reality does not mean access controls have to remain an afterthought. A practical first step is to list every user in your ERP system alongside their current role, then compare their active permissions against what they genuinely need day to day.

From there, the question becomes whether your setup can detect conflicts automatically. If two permissions together create a risk, such as the ability to both enter and approve payments, you need a mechanism that flags the overlap without relying on someone remembering to check. Cloud-based authorisation tools designed for Business Central, like those from 2-Controlware, handle this detection without requiring deep technical expertise on your team.

User permissions may not dominate the agenda at your next team meeting. But for any SMB channelling its daily operations through an ERP system, a quarterly review of who can do what inside that platform is one of the most cost-effective risk-reduction steps available.
