PowerOffice Go (operated by PowerOffice AS, Bodø, Norway, founded 1998) is one of Norway's leading cloud accounting and light-ERP platforms, used by 100,000+ businesses and 250,000+ users and consistently top-ranked for customer satisfaction in Norwegian accounting software (2020–2025). It is built modularly: accounting + invoicing, payroll, travel/expense, time registration, holiday/absence — so a freelancer can start on one module and an accounting firm can run hundreds of clients from a single console (500+ partner agencies). The product is developed, run and supported entirely from Bodø, the DPA is genuinely public (Appendix 2 of the standard service terms), and security posture is solid: ISO 27001, ISAE 3402 Type II, role-based access, 2FA, hashed passwords, delivered via the Visma Cloud Delivery Model. The procurement caveats are ownership and infrastructure, not the product. PowerOffice was acquired to a 75% majority by Visma in 2019 (the founder sold for NOK 2.4 billion), placing it inside the Visma group whose own cap table is Hg Capital (UK PE) majority with TPG (US PE) as a material co-investor. And production hosting is Microsoft Azure in an EU/EEA (Netherlands) region — EEA at rest, but a US-owned hyperscaler, with Twilio/SendGrid (US) handling email. So: a Norwegian local hero on paper, but with a US-PE ownership chain and a US-owned cloud substrate underneath. Norwegian Bookkeeping Act storage obligations are met via EEA hosting; the data is not exported outside the EEA without SCCs/controller approval.
