CFOs Adopt AI Finance Tools to Speed Reporting

Four companies are rolling out AI-powered finance systems to shorten reporting cycles, reduce errors and give finance teams more time for revenue-focused analysis.

EuroTeleSites replaced Excel-based planning with Farseer layered on its SAP backbone. The company, which manages more than 13,800 mobile towers across six central and eastern European countries, consolidated and standardised data from multiple sources to create a single source of truth. Lars Mosdorf, EuroTeleSites CFO, noted reporting and planning run about 30% faster and planning errors have fallen by more than 40%. He added that Farseer’s AI Analyst helps controllers identify the drivers behind deviations during internal reporting periods.

PostHog uses Brex for expense cards, a Stripe-based billing system for a usage-based product model, and recently moved accounting to Campfire, an AI-native ERP. For planning, the company uses Abacum to combine ERP and HR headcount data and run scenario simulations. Fraser Hopper, ops and finance lead, explained the firm now closes accounts in under 10 days, down from 20–25 days, and delivers near-real-time financial data to product, sales and marketing teams. Hopper described AI tagging and automated workflows as a factor in keeping the finance team lean while automating routine tasks.

Emergn runs NetSuite as its core ERP and uses Pulse, an in-house system, for time recording, revenue forecasts and project management, with Power BI for dashboards. Anjana Mistry, Emergn’s CFO and COO, reported month-end and quarter-end closes shortened from about two weeks to a few days after the ERP rollout. She said recent AI functions in Excel reduced time spent on modelling and variance analysis, and Microsoft Power Platform now handles repetitive workflows such as transaction coding and invoice processing. Mistry cautioned that professional judgement and oversight remain necessary when using AI tools.

Liberty Global moved from Oracle Hyperion to OneStream after the group’s operations outgrew its previous consolidation tool. Alex Johnstone, divisional CFO, described OneStream as a potential financial system of record that links management accounts from operating businesses into a single platform. He expects automation to handle routine work such as journal entries, consolidations and eliminations, enabling finance staff to focus more on strategic analysis.

Across the four firms, reported effects include faster closes, more accurate planning, reduced manual reconciliation and improved ability to run what-if scenarios. Companies report that consistent datasets and AI-enabled tagging have sped reporting and supported collaboration between finance, operations and commercial teams.
