Your Accountant Costs €600/Day. This AI Costs €49/Month. The Math Speaks.
Thursday, 9am. You sent an email to your accounting firm asking which of your top suppliers had raised prices more than 10% this year. The answer sat inside 847 invoices already filed. Your accountant replied Friday afternoon. By then, the supplier renewal was signed.
For too many finance teams, that 31-hour wait — for a question their own documents could answer — is standard, not exceptional.

What the €600 Day Pays For
External accountants at French firms bill between €80 and €150 per hour for standard advisory work. A senior partner commands €200 to €400. Monthly retainers bundle compliance filings, VAT declarations, year-end accounts, and what the industry calls "reactive advisory" — answering questions that arise between monthly closes.
Reactive advisory is where the math gets uncomfortable.
Consider a 200-employee company sending 15 to 25 questions per month that live entirely inside documents it already holds: which invoices from supplier X remain unpaid? Is cash above the March threshold? Did the October credit note arrive? Each question takes 30 to 90 minutes to locate, verify, and answer. At €100 per hour, each query costs €50 to €150.
With 20 questions per month averaging €85 each: €1,700 per month in reactive advisory. €20,400 per year. To access information the company already paid to receive.
One French industrial company with 180 employees tracked this precisely for 12 months. Total reactive advisory: €24,000 — entirely questions answerable from existing invoices, contracts, and bank statements. After deploying financial AI at €588 per year, reactive query costs fell to near zero; the accounting firm's time shifted entirely to tax strategy and audit preparation.

The Questions Nobody Sent
Visible reactive advisory spend is only half the problem.
Beneath it: the questions nobody asked.
Paying €50 to €150 per query — with an 18 to 48 hour wait — changes how CFOs behave. Questions get batched: three per email instead of one, because seven emails a week feels excessive. Decisions get deferred to the monthly meeting. Commitments get made without data because the answer did not arrive in time.
Information rationing: managing the cost of asking, not the cost of not knowing. Finance questions get skipped not because they are unimportant, but because each one costs €85 and two days. The unanswered questions never appear on the invoice . Most P&L analyses miss them entirely.
SMEs that track "questions answered by external accountant" as a cost category almost always find that 40 to 60% of their accounting spend went to questions answerable from their own documents. That is the number worth staring at.
Meanwhile, some queries found a different route: employees copying invoice data and supplier pricing into ChatGPT or Copilot for faster answers. That data left company systems permanently — US servers, no audit trail, no sovereignty, no recall. Seventy-seven percent of employees using AI tools for work paste corporate data into prompts (LayerX, 2025). In finance, where the data is confidential and regulated, that habit carries risks the advisory invoice never reflects.

Eight Seconds. Sourced. €49/Month.
Stralevo is a financial intelligence layer. It sits between finance teams and their accounting software, ingests every financial document ever received — invoices, receipts, contracts, bank statements — and reads everything in each one. Not the 5 fields standard accounting software captures. All 15 to 40 fields per document: serial numbers, warranty terms, payment conditions, delivery references, contract clauses, supplier contacts. All of it queryable through plain-language questions.
Questions like "which suppliers raised prices more than 10%?" get answered across 847 invoices in seconds, every answer source-cited: the exact document, page, and line item. "Is invoice 4472 paid?" Answered. "When does the October server warranty expire?" Answered. "Which contracts renew before June?" Answered. Any question, any time, full provenance.
Unlimited questions, instant sourced answers, available 24 hours a day, seven days a week — including Sunday nights when a decision cannot wait. At €49 per user per month — €588 per year — this costs less than a single hour of senior accounting advisory.
Do the math: €20,400 per year in reactive advisory versus €588. No spreadsheet required. Just arithmetic.

What Changes for the Accountant
Let's be precise: none of this is an argument against accountants.
Great accountants at €100 to €400 per hour create irreplaceable value — when they are doing work that requires decades of judgment. Tax strategy. Audit preparation. Navigating the grey-area deduction worth €40,000. Managing a URSSAF dispute (the French body that collects social security contributions — disputes carry substantial financial penalties). That expertise does not live inside documents. No AI answers those questions correctly.
Here's the boundary: Stralevo handles the reactive queries that ARE in the documents. Invoice status, supplier pricing, cash positions, payment tracking, contract terms — all answerable from existing PDFs, just not quickly, not at any hour, not without a financial intelligence layer sitting in front of them.
Several mid-size accounting firms in Sweden now give clients self-service access to financial intelligence for common queries. The result: client callbacks dropped by 60%, and remaining conversations shifted entirely to strategy, complex compliance judgment, and planning. Accountants describe doing better work, not less work. The partner who stops spending Tuesday afternoons searching through invoices has Tuesday afternoon free for the advisory conversation that actually required their expertise.
No profession is threatened here. A profession returning to its highest function — that is what the transition looks like.

The Regulations Expanding the Math
CSRD — the Corporate Sustainability Reporting Directive — applies to many mid-market European companies from 2025 onward. It adds dozens of new financial data requirements: energy costs by category, supply chain sustainability data, social spending metrics, governance figures. A company currently answering 20 financial questions per month will need to answer 35 to 50 for CSRD compliance alone. At reactive advisory rates, that is €1,500 to €4,000 per month in new compliance queries. At €49 per month, Stralevo answers all of it from existing documents.
On-demand FEC production — the Fichier des Écritures Comptables, the standardized accounting export that French tax authorities can demand with 15 days' notice, carrying a €5,000 penalty for non-compliance — is generated instantly. No weekend scramble, no manual assembly, no gap-fill.

Your Calculation
Pull last year's accounting invoices. Separate the compliance work — VAT filings, year-end accounts, social declarations — from reactive queries: questions about invoices, suppliers, payments, cash positions, and contract terms. Multiply query hours by the hourly rate. That number is what your company currently pays to access information it already holds.
Set it against €588.
Most companies running this comparison for the first time find the left number sits between €10,000 and €40,000. Finance directors who restructured advisory spend — routing reactive queries to Stralevo and freeing accounting firm time for strategy — describe the same outcome: accountants do better work, relationships deepen, and total advisory costs fall. Not because the accountant became less valuable. Because they finally stopped doing work that never needed their expertise.
CFOs who can ask any financial question and receive a sourced answer in seconds ask more questions, make faster decisions, and catch the supplier overcharge before it compounds for another quarter. The average reactive query costs €85 and waits 31 hours. Stralevo costs €49 per month for all of them, answered in 8 seconds each.
The math was always this clear. Now it has a price tag.
