For Swiss Treuhänder · Engineered in Zurich
From messy client inbox to filed tax return. Fiduex handles the chasing, reading, and sorting - you handle the advising.
Data never leaves Switzerland · revDSG / Swiss FADP compliant.
The spring bottleneck
Boutique fiduciaries burn their spring on the same repetitive line — chase, receive, sort, re-type, reconcile. The work is identical across dossiers, and almost none of it is advisory.
Weeks of polite emails, voicemails, and reminders asking for the same Lohnausweise, 3a certificates, and broker statements.
Files trickle in by email, WhatsApp, paper, and the occasional photo of a laptop screen.
Someone renames, folders, and matches every document to the right client, year, and category.
Foreign broker PDFs get re-keyed into the tax software, line by line, dividend by dividend.
Numbers don't tie. Open the original. Find the typo. Repeat until April.
The pipeline
Fiduex is a flat, opinionated workflow — not another portal your clients have to learn. Upload a roster, and the factory line runs itself.
01 · Ingestion
You drop a CSV or Excel of clients. We nudge them through white‑labeled WhatsApp or emails. Your clients respond with the files. No password, no app, no account.
02 · Classification
Every file is parsed and categorised against the Swiss tax taxonomy automatically. The checklist flips green as documents arrive.
03 · Export
Review extracted values next to the original page. Export all data directly to Dr. Tax, AbaWeb, NestTax or Klara — no manual typing. Or push straight into your tax software.
Standard communication runs over Swiss-hosted secure email. WhatsApp is a strict client-side opt-in.
Never type a broker statement again
Interactive Brokers, Revolut, eToro, DeGiro. We extract every dividend, buy, sell and withholding, normalise ISINs, and enrich each position against the official ESTV ICTAX database.

Beyond the salary certificate
After securities, real estate is the second biggest time‑sink in a Swiss dossier. A Lohnausweis demo only shows the easiest case. We handle the rest.
Cantonal rules and rates applied automatically — ZH, BE, VD, GE and the other 22 — including reduced rates for under‑use.
UBS, ZKB, Raiffeisen, Migros Bank, PostFinance and cantonal banks: interest, amortisation and balance pulled into Schuldenverzeichnis.
We compute both options per object and flag the better choice. Invoices are sorted into werterhaltend vs. wertvermehrend.
Steuerwert, Lage, Nutzung and foreign property with Satzbestimmung — exported straight into Dr. Tax, AbaWeb, NestTax and Klara.
