Expense management at Go Geothermal was once a daunting and inefficient process. Its employees relied on outdated spreadsheets to manually track their expenses while retaining paper receipts. Monthly expense reporting also required hours of administrative work, creating bottlenecks for both the employees submitting the expense reports and the finance team who was reviewing them.
Tim Williams, Executive Director at Go Geothermal, described the situation as a “massive bugbear,” with expense management consuming nearly four hours per month for a typical employee. The lack of real-time visibility into spending trends also limited the company’s ability to manage its budgets effectively.

In a wider bid to improve its internal software and sales technology, Go Geothermal partnered with Ascent Business Solutions—a Zoho Premium partner—and was introduced to the Zoho suite of products. Tim soon discovered the Expense application, which was to become his “favourite solution of Zoho”. Streamlining expense management and enhancing operational efficiency, Tim considers the application to have brought “an undeniable tangible benefit” to Go Geothermal.
Modernising its expense management processes, the platform allowed Go Geothermal’s employees to auto-scan receipts, associate them with specific trips or monthly reports, and submit their expenses in just minutes. The built-in approval workflows also streamlined operations for the finance team, ensuring all expenses were within budget and properly documented. Integration with the company’s corporate credit accounts further simplified reconciliation, and real-time insights illuminated spending trends, providing better visibility and control over expenses.

With Zoho Expense, Go Geothermal has transformed its expense management process, achieving:
Overall, Tim enjoys Zoho Expense’s ease-of-use and simplicity, as well as its intuitive design. Expense has given him renewed confidence in the accuracy of the company’s financial reporting.

By digitising its expense processes, Go Geothermal has not only saved significant time but also built a foundation for better financial control and accountability across the business.
