For once, everyone you need to answer the hard questions about AI in finance will be in the same room. Stacks Summit. London, 29 September. 300 of the UK's most senior finance leaders, one afternoon. Invitation only. Waiting list open:

Today we're launching the Cash Application agent. It reads your remittance advice, matches every incoming payment to the right invoices, and explains each match back to source in plain English. Never apply a payment by hand again.

Today we shipped an agent that reconciles and resolves your VAT. A deterministic three-way match across your GL, VAT return and the tax authority's figures, before you file. Every difference explained in plain English, traced to source. Recs in minutes, not days.

Reassigning checklist tasks one by one is the kind of small friction that quietly slows down a close. People go on leave, ownership shifts, due dates move. Bulk actions fix that. Select the tasks, an action bar appears at the bottom of the screen, reassign preparer or reviewer, shift due dates, or delete in one go. Conflicts stay surfaced so nothing slips.

We just shipped the biggest Flux update since launch. Until today, Flux only did MoM variance. It now runs four comparison modes, with AI explanations across all of them: → Monthly → Quarterly (any 3-month block) → Yearly (any 12-month block) → Custom (incl. fiscal YTD) Use flux analysis for board decks, auditors, group reporting and more: all in one tool.

"Stacks felt like it was built for the way we actually want to work." - Ida Salmen, Cost Accounting Manager at @epidemicsound The full story of how their finance team rebuilt their close 👇

Most variance commentary stops at "what happened." The best explains why it matters, and what to do next. Christian Wattig (@Wharton FP&A) and @albertmalikov are going live April 2nd for a 60-min masterclass on AI-driven variance analysis. You'll walk away with: → The "What, Why, So What" framework → The ARCTIC method for finding the real story → How to generate variance commentary in seconds with AI Sign up link in comments 👇

Today we're launching Flux AI Agent. Flux investigates variances the way a senior analyst would. It pulls transaction-level evidence directly from your ERP, enriches it with full context, flags outliers, and writes explanations with citations back to source data. What used to take days happens in seconds.
