Why Choose Construction-Specific Accounting Software Over Generic Systems

Generic accounting systems like Sage, QuickBooks, and Xero may offer basic financial functions, but they fall short when it comes to meeting the unique demands of the construction industry. From managing subcontractors and job costing to handling retentions and valuations, these systems lack the specialised tools your construction business needs.

Without a dedicated solution, your business must rely on numerous manual processes to cover essential construction-specific requirements. Does any of this sound familiar?

  • Manually verifying and managing subcontractors via the HMRC/ROS online system

  • Tracking job costs across multiple spreadsheets, leading to errors and inefficiencies

  • Losing track of retentions, meaning missed revenue opportunities

  • Going over budget on projects because your accounting system doesn’t provide clear visibility of costs vs. budget, resulting in tighter margins

Evolution Mx construction accounting software solves these challenges by streamlining key construction processes, reducing manual tasks, and improving accuracy across your entire operation.

Every construction business has unique financial management needs. That’s why Evolution Mx comes with 7 essential core modules designed for the day-to-day financial operations of your business.
