Why this guide exists (and why not to follow it)
Swiss fiduciaries mostly bill by the hour: CHF 120–220/h for a senior, less for a junior who — after 40 minutes hunting your document — will still bill clarifications at full rate. Every vague email, every shoebox of receipts, every 28 February «urgent» is sold time. Not personal hate: budget hate.
We collected behaviours that appear in every Friday office story across Swiss firms. Practice them all and you will not only pay double: you risk the termination letter (Art. 404 CO) — or worse, a fiduciary who bills the frustration without saying so.
Read this as satire with real utility: each «sin» includes bill impact and the antidote. At the end: the model client checklist — the one fiduciaries mention in sales meetings.
The doubled-invoice formula
Rough estimate for an SME or sole prop with 200–400 entries/year. Multipliers add up.
| Behaviour | Time multiplier | Typical extra/year |
|---|---|---|
| All year's papers in one box in March | ×2.5 | CHF 800–1,500 |
| «Urgent» email without organised attachments | ×1.8 | CHF 400–900 |
| Same document sent 4 times in different formats | ×1.5 | CHF 200–500 |
| Phone call for every 2-minute doubt | ×2 | CHF 600–1,200 |
| Untracked «phone» corrections | ×1.7 | CHF 300–700 |
| VAT receipts delivered on deadline day | ×3 (rush) | CHF 500–2,000 |
Document sins: chaos as a sport
The fastest way to make your fiduciary hate you silently: turn every minute into archaeology.
1. Hand over a box of receipts in March
Two hundred faded receipts, some in two currencies, some undated. «Here's all of 2025, good luck.» The junior spends 6 hours sorting before the first entry.
6 h × CHF 150 = CHF 900 pre-work alone. Plus reclassification the senior bills at full rate.
Digitise monthly. Naming YYYY-MM-DD_supplier.pdf. Client portal or shared cloud.
2. Send tilted WhatsApp photos of receipts
Half the invoice cut off, flash glare, PDF from 14 screenshots. «You can read it fine.»
Each illegible photo = re-send request + 15 min chase. ×30 docs = half a day gone.
Scan app with PDF/A, one invoice per file, quality check before upload.
3. Mix private and business in one PDF
One file «expenses_2025.pdf» with vet bill, fuel and supplier invoice. The fiduciary must split — and ask you about every line.
Rejected deductions risk + reclassification hours. Double work, double bill.
Separate business account. Only professional movements in books.
4. Restart invoice numbering mid-year
«I restarted at 1 because I preferred it.» Duplicates, gaps, VAT sequence rebuild.
2–4 hours reconciliation + VAT stress.
Continuous sequential numbering. Credit note to cancel, never reuse numbers.
Communication sins: death by a thousand emails
Every channel without rules becomes billable.
5. Subject: «Urgent!!!» (empty body)
No attachment, no period, no amount. Just «call me now». The fiduciary interrupts work on 12 other mandates.
Interruption + 20 min call + follow-up email. CHF 80–150 per phantom «urgent».
Structured subject: «Mandate Rossi – VAT Q4 – supplier X – rate question». Attachments in first message.
6. Reply on 15 threads about the same topic
Fragmented across Gmail, WhatsApp and «that February mail». Nobody has the full picture.
Reconstructing the story = unbudgeted time, often not discounted.
One thread per topic. Portal messaging tied to the document.
7. Ask «how much tax?» without sending anything
10 December. No bank statements, no draft close. Expect answer in one hour.
Impossible or «wide» estimate you dislike. Second round = second bill.
Dashboard updated during the year. Specific questions with numbers attached.
8. CC the fiduciary on partner disputes
Long emotional emails on non-accounting contracts. They are not your lawyer.
Reading time not billable but taken from other clients — or billed as generic advice.
Accounting, tax, payroll only. Lawyer for legal. Coach for strategy.
Timing sins: deadline as surprise
Client urgency is always fiduciary urgency — with implicit surcharge.
9. Bring full VAT quarter on 28 February
Deadline 28 February. You arrive the 27th with «just this left». Queue of 40 identical mandates.
Unwritten rush premium: extra hours, weekend, junior overtime.
Send docs within 10 days of quarter-end. Shared calendar with auto reminders.
10. Change numbers after the draft
«I redid Excel, revenue is different now.» After the fiduciary closed the P&L.
Redo draft accounts, return, auditor explanations. 3–8 hours minimum.
Freeze data at a date. Later changes = new tracked assignment.
11. Ignore requests for weeks, then «urgent»
Three reminders ignored. Friday 5 pm panic call.
Missed tax deadlines → interest at your cost + fiduciary rush bill.
Internal SLA: reply within 5 business days. One company contact person.
«Expert» sins: overwriting the professional
Nothing runs the meter like explaining their job badly.
12. «Google says everything is deductible»
German blog posts applied to Switzerland. The fiduciary must correct, document and carry liability (Art. 398 CO).
Unrequested defensive advice + awareness declaration to sign.
Ask «why not in canton X?» with legal reference. Listen to the answer.
13. Insist on illegal «simplified» accounting
«Don't book that invoice, nobody checks.» A professional cannot accept (complicity Art. 305 SCC).
Loss of mandate + possible reporting. Double bill becomes the smallest problem.
Seek lawful optimisation. If you don't trust them, change fiduciary — don't ask for illegal.
14. Challenge every invoice line afterwards
«Why 0.3 hours to open my email?» Micro-disputes over 12 months of correct work.
Complaint handling time > disputed amount. Some firms add admin surcharge.
Ask for rates and budget upfront. Portal with transparent hour reports. Annual budget agreed.
Alternative version: become the favourite client
Same professionals, half the bill, zero reminders. Not likability: process.
- One internal contact with access to accounts, bank and documents
- Structured monthly upload (portal or folder with naming convention)
- Questions batched in one 30-minute quarterly meeting
- Shared deadline calendar with alerts 14 days ahead
- Cloud software where the fiduciary sees data live without digging
7 serious tips after the satire
- Ask for the rate card and indicative annual budget — avoids surprises and fights
- Client portal is not luxury: it's how not to pay for the same invoice four times
- If the fiduciary doesn't reply, documents are often missing — not ignorance
- One good onboarding hour saves ten hours of corrections
- Don't mix fiduciary, lawyer and coach: three budgets, three skills
- AccountEX aligns client and fiduciary: fewer emails, less chaos, fewer hours
- If you recognise 5+ sins, don't change fiduciary — change habits
