Work Smarter, Not Harder: Top 5 AI Prompts Every Finance Professional in Belgium Should Use in 2025

Belgian finance teams are in a moment of practical transformation: treasury and FP&A leaders need faster, audit‑ready cash forecasts and controllers want cleaner month‑end closes, and AI prompts deliver those outcomes by turning questions into board‑ready answers.

Local momentum shows why prompts matter - EY's Diegem breakfast on “How can treasury management leverage AI to optimize cash flow and liquidity?” highlights real use cases for cash forecasting and liquidity optimization, while Deloitte Belgium's PairD rollout demonstrates how firms are building secure internal chatbots to free up teams across 5,900+ employees.

Prompt libraries and playbooks now let treasurers reforecast a 13‑week cash view or generate variance narratives without stitching together six bank portals, and practical training like Nucamp's AI Essentials for Work teaches prompt writing and on‑the‑job AI skills for finance roles (15 weeks; Register for AI Essentials for Work).

The bottom line for Belgium: learn to ask the right prompt, and AI becomes the fastest route from data to decision.

"The potential of generative AI is immense. It will enable us to drive innovation internally and with our clients, improve efficiency, be more client‑centric, support sustainable processes as well as launch new business models," explains Patrick De Vylder, managing partner Delivery Transformation and Innovation.

Selection focused on practical impact for Belgian finance teams: prompts were scored for immediate audit‑readiness, how much they cut spreadsheet risk, and whether they respect local tax and market quirks - for example Belgium's transaction tax (TOB) ranges and the 30% dividend levy that make domicile and distribution rules consequential (see Curvo's ETF checklist for Belgians).

Prompts that automate reconciliations or tidy formulas scored highly because they directly reduce month‑end friction and human error (learn more on Excel formula automation to cut errors), while prompts that incorporate privacy and handling rules were favoured to keep deployments GDPR‑safe for Belgian firms (see the GDPR‑compliant AI practices guide).

Each candidate prompt was validated against three practical checks: does it lower operational risk, does it avoid predictable Belgian tax/market traps, and can it be audited or documented quickly - a small upfront prompt tweak can save a finance team from a costly 1.32% TOB bite or a late close, so choice of prompt matters as much as the model used.

Top Prompt 1 - Cash Flow Optimizer (Treasury) turns scattered bank feeds and ERP balances into a single, audit‑ready cash picture so treasurers stop juggling multiple portals and start acting on confidence: the prompt ingests intraday feeds, flags unusual flows, suggests sweeping/pooling moves and runs AI‑backed scenarios to sharpen a 13‑week view - an approach proven in practice when BearingPoint helped KWS implement a centralized treasury platform for “full visibility and control” of liquidity and cash, and when platforms like Serrala promise real‑time cash visibility with up to 99% reconciliation automation.

Pairing that infrastructure with model‑aware prompts from J.P. Morgan's playbook for AI‑driven forecasting can cut traditional forecast error rates dramatically while producing interpretable scenarios for auditors and the board.

For Belgian teams facing TOB and dividend nuances, the Cash Flow Optimizer prompt focuses on currency‑corrected positions and audit trails, delivering a tangible payoff: fewer late payments, clearer intraday visibility, and the calm of a single point‑of‑truth replacing the old scramble across bank portals.

“We see a strong case to capture ‘quick wins' that can deliver benefits within a short-time frame and with minimal disruption to critical processes and infrastructure.”

The Forecast Refresh & Scenario Planner prompt turns rolling forecasts from a tedious, error‑prone chore into a fast, auditable rhythm: it pulls live actuals, re‑runs global assumptions, and spins up side‑by‑side scenarios so FP&A can show management the impact of a pricing change or a short cash spike in seconds rather than spreadsheets‑worth of manual updates.

By combining driver‑based logic with automated data pulls and interactive visuals, platforms like Workday Adaptive Planning real-time reporting for financial planning and Prophix One rolling forecasts and AI forecasting insights make it simple to answer “what if” questions, document assumptions for auditors, and keep cross‑functional owners aligned.

For Belgian finance teams that must balance tight reporting cadences and GDPR‑safe workflows, this prompt replaces frantic last‑minute reconciliations with calm, repeatable refreshes - like swapping a tangled ball of yarn for a neatly wound spool that leaders can trust when the board asks for an immediate scenario comparison.

“Knowing that the analysts on my team are entering their forecasts, that we can refresh everything and automatically re-run global assumptions and allocation forecasts, and that I can look at the updated forecast immediately is key.”

Top Prompt 3 - Board Deck Generator (CFO) automates the painful alchemy of numbers, narrative and governance so Belgian CFOs can hand a concise, audit‑ready deck to directors in minutes instead of burning weekends polishing slides: the prompt ingests finalised forecasts and driver‑based metrics, applies the three‑slide starter logic many CFOs use (headline “good/bad/ugly,” a tight table of metrics, then P&L & cash), and outputs a clear executive summary, scenario pages and annotated assumptions that align with pre‑board rituals and cross‑functional sign‑off.

By codifying best practices from the CFO Leadership Council and Cube's short guide to crafting captivating quarterly decks, and combining them with AI‑first storytelling patterns (see how AI tools can build board slides quickly), the generator enforces alignment with department heads, surfaces risks for “disagree and commit” conversations, and embeds the cash‑and‑scenario emphasis Belgian CFOs learned from crisis playbooks - turning a sprawling slide pack into a sharp strategic briefing that lets the board decide faster and frees leaders to debate, not dig for numbers.

“Virtually everything in business today is an undifferentiated commodity, except how a company manages its information… how you manage information determines whether you win or lose.”

Top Prompt 4 - Reconciliation & Audit Readiness Summary (Controller) gives controllers a playbook to turn chaotic month‑end reconciliations into an audit‑ready rhythm that Belgian teams can trust: the prompt automates account reconciliations, flags duplicates and exceptions, ties supporting documents to ledger lines, and produces a clear trail for auditors so close packs aren't a weekend‑long firefight but a routine handoff - think swapping a nightly scramble for a five‑day, verifiable close.

Built on the practical checks in Prophix's month‑end close checklist and the document‑centralisation strengths of DocuWare's workflow guidance, the prompt enforces ownerable checklist items, sequences dependent tasks, and surfaces anomalies for quick review; when combined with GDPR‑aware deployment patterns from the Nucamp AI Essentials for Work syllabus, controllers keep sensitive Belgian data secure while speeding reconciliations and reducing spreadsheet risk.

The result is cleaner balance sheets, fewer auditor queries, and a controller who can prove every number with a timestamped source rather than a guess.

“A close checklist is being able to track when something is done and who's doing it, so you can keep on top of everything.”

Top Prompt 5 - AR Prioritization & Collections Planner (Accountant) turns aging reports into an action plan that Belgian accountants can trust: it ingests invoice ageing, predicts likely payment dates, segments customers by behaviour and risk, and spits out a ranked daily worklist so collectors focus on the handful of accounts that will move the cash needle today.

Built on proven AR best practices - from clear invoicing and online payment options to automation that shortens DSO - this prompt automates reminders, proposes tailored collection strategies (early‑payment discounts, payment plans) and surfaces disputes for swift resolution, while preserving a neat audit trail; see how J.P. Morgan frames the AR process and KPIs in its accounts receivable management guide.

Belgian teams will recognise the hands‑on advantage in the AiVidens case study, where colour‑coded dashboards and payment‑date predictions guide juniors and reduce churn in credit roles, effectively turning a chaotic dunning pile into a single, triaged inbox that collectors can clear with confidence.

Belgium's playbook for safe, useful AI is already in place: the national AI strategy prioritises trustworthy tools, skills and multi‑level governance, so finance teams can innovate without trading away compliance (Belgian AI strategy: national AI strategy report for Belgium).

Local industry data show AI is not just hype - FinTech Belgium and Sailpeak's Barometer finds wide adoption across banks and insurers (84% using predictive AI; 79% exploring GenAI), and it stresses the EU AI Act and transparency as near‑term constraints for firms.

At the same time, ECB analysis flags systemic risks (supplier concentration, data quality and cyber exposure), so pragmatic pilots that pair strong governance with measurable ROI are essential.

Start small: pick one of the five prompts above, run a documented pilot with clear data lineage and human sign‑offs, and scale only after controls and audit trails hold up.

For teams that need hands‑on prompt training and GDPR‑aware deployment patterns, a practical course like Nucamp's AI Essentials for Work: practical AI skills for the workplace teaches prompt writing and on‑the‑job AI skills; when governance, data quality and a single, repeatable prompt are aligned, the payoff is real - faster closes, cleaner audits and fewer weekend fire‑drills.
