How a UK renewable energy consultancy replaced disconnected SaaS tools with a single unified ERPNext platform — going live in just 5 weeks.
Biosus Energy is an Aberdeen-based renewable energy consultancy helping businesses achieve net-zero targets. They deliver tailored energy solutions for organisations spending £500k+ annually on energy — from feasibility studies through to full project delivery.
As the business grew, their collection of disconnected SaaS tools with per-user licensing became increasingly costly and unmanageable. Sales pipeline, project delivery, and financial data lived in separate systems with no unified view — and manual data re-entry was eating into billable hours.

Multiple SaaS subscriptions with per-user licensing meant costs scaled with every new hire — and none of the tools talked to each other.
Sales pipeline, project delivery, and financial data lived in separate systems. Management had no single view across the business.
Information had to be copied between systems manually — wasting hours on admin and introducing errors into reporting.
We implemented ERPNext as a unified platform for Biosus Energy — replacing their fragmented SaaS stack while keeping Xero for accounting via real-time integration.
A CRM pipeline with custom stages tailored to energy project sales — from initial enquiry through feasibility, proposal, and contract award.
Full project management with timesheet tracking — giving visibility into project progress, resource allocation, and billable hours.
Accounting stays in Xero where the team is comfortable, with real-time integration keeping invoices, payments, and financial data in sync with ERPNext.
