The problem

Before switching to the CRM, the business ran entirely on Excel and paper. For large-scale commercial contracts (5,000–10,000 panel jobs), this meant hours of manual reconciliation every month and financial visibility that only existed after the work was done — not while decisions were being made.

  • A separate Excel file for every customer, tracking costs and income individually.
  • Supplier accounts and other costs tracked in yet another set of spreadsheets.
  • At month- and year-end, someone had to manually pull numbers from every file into one summary just to see the real picture.
  • Cleaning jobs were scheduled on paper, with no easy way to plan ahead or share the schedule.
  • No visibility into which invoices were missing, which payments were overdue, or the true average cost per panel.
  • No easy way to see what type of customers made up the business, or spot patterns worth acting on.

The solution

The business moved scheduling, customer management and financial tracking into one system. Each need was met by a real screen in the app:

Digital job scheduling

Select a customer, set the cleaning agenda, and generate a downloadable schedule instead of managing it on paper.
