Expert/M is the bookkeeping module inside Wolters Kluwer’s Adsolut Suite. It sits next to Adsolut Personal Income Tax, Adsolut Corporate Income Tax and Adsolut Annual Accounts, and is installed on the firm’s workstation or office server. The desktop version has no live REST API: integration runs through the documented XML import/export schema (Extra → Importeren externe applicaties → XML → Expert/M).
1. The Expert/M integration challenge
Expert/M Plus ships with a well-documented XML import/export schema. The accountant exports the trial balance (saldibalans) or journal as XML, and Upswitch reads that schema directly. No screen-share session, no manual CSV cut-and-paste: one file upload per fiscal year, and the valuation engine has what it needs.
- In Expert/M Plus, export via Extra → Importeren externe applicaties → XML → Expert/M (trial balance or journal).
- Upload the XML in the Upswitch portal: pick the dossier, the fiscal year, and the file.
- The engine validates the PCMN account codes, maps to MAR classes, and runs the same classification and normalisation pipeline as the live cloud connectors.
2. What Expert/M data delivers for EBITDA normalisation
Expert/M books against the Belgian PCMN (Plan Comptable Minimum Normalisé) chart of accounts. That is the exact same classification Octopus and Silverfin emit on BE dossiers, which means identical MAR routing (class 60 → COGS, 62 → personnel, 6200* → director compensation, 63 → depreciation, 65 → financial expense, 67 → taxes, 68/69 → extraordinary).
- Saldibalans per fiscal year (account, label, debit, credit, balance).
- PCMN account numbers from 4 to 8 digits — our classifier recognises both the full code and the 2-digit class prefix.
- Period information (start/end of the fiscal year) so non-calendar fiscal years are automatically flagged.
- CODA and SODA movements can be loaded for cash-flow signals, but are not required for the baseline valuation.
3. Activation for Expert/M accountants
In the Upswitch portal you connect Expert/M the same way you connect any other provider: dossier code + company name + (optional) VAT number. Then you upload the saldibalans XML for each fiscal year you want to value. No API tokens, no OAuth redirect, no waiting on partner onboarding with Wolters Kluwer. The connection works today, with the Expert/M install you already have.
4. Expert/M in Belgian normalisation practice
Belgian accounting firms running Expert/M typically serve a mix of family businesses, regulated professions and SMEs. In that segment we see recurring patterns: director compensation below market, private use of company assets booked as operating expense, retained earnings used as a dividend alternative. Our MAR classifier surfaces these via the PCMN classes and flags them in the Defensibility Co-pilot.
Normalised EBITDA is benchmarked against the Upswitch Index sector ranges. For a Belgian manufacturing or services SME, the accountant sees their normalised EBITDA next to the live market multiples for that sector.
Frequently asked questions
Does the integration work without Expert/M Online?
Yes. Most firms run Expert/M on-premise. Our connection uses the XML saldibalans export every Expert/M Plus install ships with (Extra → Importeren externe applicaties → XML → Expert/M). No extra licence required.
How long does the first connection take per client?
The saldibalans export in Expert/M Plus takes 1-2 minutes per fiscal year. The upload + parsing in the Upswitch portal is real-time. For a new client with three historical years you are typically done in under 10 minutes.
What about CODA and SODA files? Does Upswitch need them?
Not for the baseline valuation. The trial balance contains everything we need for MAR classification and EBITDA normalisation. CODA/SODA adds cash-flow detail we can read for live cash-flow signals, but for the SME valuation it is optional.
