Both founders had bad experiences with tax advisors before. Their firms were barely digital, rarely got in touch on their own and stayed vague about costs. They wanted the new company to work differently, so they chose Integral.
Getting started with Integral
Onboarding took six days. Connecting the tools the founders already used was part of that start, so transactions and documents reached Integral from day one. Nobody uploads anything by hand or sends it by email.
I’m really happy with Integral at the moment. It’s exactly what I stand for: efficiency and digital processes instead of wasting resources.

Qonto and cleverlohn in one set of books
GNU Energy’s Qonto business account and its payroll through cleverlohn are connected to Integral. Every transaction and payroll run arrives on its own, so nobody at GNU Energy exports a file. The platform matches each one and prepares the booking.

Predictable costs
Their previous firms billed by the hour, so the cost was only clear afterwards. At Integral, the team pays a fixed monthly price for all agreed services. The founders always know what to expect and ask questions without thinking about the next invoice.

Working together day to day
All questions go to one place on the Integral platform, instead of spreading across emails and phone calls. A dedicated contact who knows the company answers them there. Letters from the tax office and all tax documents are on the platform too, ready to view and download at any time.
AI agents prepare the ongoing bookkeeping. Integral’s tax team of experienced tax advisors and accountants checks every step before a BWA goes to GNU Energy or a VAT return is ready for approval.
The document reconciliation rate was 100% from March to July and in October, 92% in August and 96% in September.

Efficiency through AI
GNU Energy automates its own work too. Through Integral’s MCP interface, the team handles invoices and reports straight from its own tools. On top of that, the founders built their own AI agents to automate more of their back office.

We’re looking for a long-term relationship with Integral. I’m super convinced Integral is the right partner for bookkeeping and tax advisory.
Six people, one tax team.
Tax advisors, auditors and tax operations work in the same platform as Hilko and Kamil. Every question reaches someone by name.
