Microsoft, KSeF, and Polish energy: New operational costs and deadlines.

This week's signals highlight a recurring pattern in business operations: changes that are not immediately obvious but carry significant future costs or penalties. These are not 'big bang' announcements. They are often quietly scheduled or introduced with grace periods that lull businesses into inaction, only to sting later. Signal: Microsoft 365 Business Basic and Standard prices increase from 1 July 2026. Why it matters for European SMBs: A 40-seat Business Standard tenant will pay approximately 1,500 USD more annually. This increase applies at your specific renewal date, not a universal one, and the price gap to Business Premium has significantly narrowed, making the upgrade for enhanced security a more cost-effective option than before. Signal: KSeF e-invoicing became mandatory for most Polish companies on 1 April 2026. Why it matters for European SMBs: While fines for non-compliance are delayed until 1 January 2027, the obligation is active. This offers a critical window to practice issuing and receiving live KSeF invoices without financial penalty, avoiding potential fines up to 100% of the VAT amount next year. Signal: Poland's April 2026 energy law rewrite cut grid connection permit validity from 2 years to 1. Why it matters for European SMBs: Projects now face a faster clock to complete, with reserved grid capacity expiring sooner. The increased non-refundable deposit and new application fees also raise the initial cost and risk for new energy connections, requiring closer project management and financial planning. These changes demand proactive review of your contracts, software, and permits to avoid unnecessary expenditure or penalties.
