How Pestokill Achieved a 72% Reduction in Overdue Balances

Pestokill has been protecting UK businesses and homes from unwanted invaders since 1985, growing into the nation’s largest independent pest controller. With qualified technicians across every city in England, Scotland, Wales, and Northern Ireland, their service is prompt and effective.

As the company expanded across the UK, its technicians kept solving problems in the field while the finance team managed a growing volume of accounts receivable behind the scenes. To support that growth, Pestokill turned to Kolleno.

As Pestokill grew across the UK, the manual collections process stopped keeping up. The core issue was fragmentation. Invoice information, customer records, and payment statuses lived in separate systems, so the finance team could never get a unified view of what was outstanding. Follow-ups were missed and payments slipped.

On top of that, every communication was manual. Each invoice notification, reminder, and escalation had to be written, sent, and tracked by hand. As volumes grew, that consumed hours and led to inconsistent messaging and gaps in follow-up. Without a way to prioritize, high-value overdue accounts sometimes got the same attention as small ones.

Kolleno gave the team a single place to work. Through a seamless Sage integration, financial data now synchronizes automatically, creating one source of truth for accounts receivable. When an invoice is created in Sage it appears in Kolleno, and when a payment is recorded it updates across both platforms instantly, removing manual data entry and reconciliation between systems.

With everything in one view, the team could finally prioritize. Kolleno’s task manager assigns work based on predefined rules, so high-value and high-risk accounts get the right attention, and the finance team starts each day with an organized, prioritized list instead of reacting to whatever is loudest.

The results followed quickly. In the first three months, Pestokill cut its total overdue balance by 72%. Automation now saves the team 2.5 hours every day, and 75% of outbound communication goes out automatically each month.

The bigger change is in how the team spends its time. Before Kolleno, collections were reactive and manual, with hours lost to tracking overdue invoices, writing individual follow-ups, and updating spreadsheets. Now the routine work runs on its own, and the task manager makes sure nothing falls through the cracks while high-value, high-risk accounts get the attention they need. Less time goes to the mechanics of collections and more goes to the accounts that need real judgment.
