1. Efficiency Potential in Recurring Service Billing

Swiss consulting firms, law offices, IT service providers, and fiduciaries generate a substantial portion of their revenue from periodic retainers, service level agreements (SLAs), and subscription models. Manually creating invoices month after month generates excessive administrative overhead, invoicing delays, and liquidity bottlenecks caused by late debtor collections[cite: 2].

An automated billing engine schedules recurring invoices, issues electronic PDFs with compliant Swiss payment sections, and reconciles incoming transactions against banking feeds in real time[cite: 2].

ISO 20022 / CAMT Payment Reconciliation

By importing camt.053 (bank statements) and camt.054 (credit notifications) files, open receivables in ACCSoft are cleared automatically without manual data entry. The system matches incoming payments flawlessly via structured 27-digit QR reference numbers.

2. The Swiss QR-Bill Standard by SIX Group

Invoicing in Switzerland must comply with the Payment Standards defined by SIX Interbank Clearing [cite: 4]:

  • Payment Part Components: Swiss QR Code (containing the Swiss Cross), receipt slip, and structured creditor/debtor data blocks.
  • QR-IBAN and References: Full support for the 27-digit structured QR Reference as well as the ISO 11649 Creditor Reference (SCOR) for international B2B transactions.
  • Strict Dimension & Typography Standards: Exact dimensions (Payment part: 105 × 148 mm, Receipt: 105 × 62 mm) using approved typography (Liberation Sans, Arial, or Helvetica).

3. Legal Framework: Default, Dunning, and Art. 102 ff. CO

Debt recovery and statutory default rules are governed by the Swiss Code of Obligations (CO, SR 220) [cite: 4]:

  • Incurring Default (Art. 102 CO): When an exact expiry date has been agreed upon (e.g., "payable within 30 days by March 31"), the debtor is automatically in default upon expiration of that day without requiring a reminder (Art. 102 para. 2 CO). Without a fixed date, a formal dunning letter is legally required.
  • Statutory Default Interest (Art. 104 CO): By law, default interest is fixed at 5% per annum from the date of default, unless a higher rate was contractually agreed upon.
  • Dunning Fees: Administrative reminder fees may only be billed if explicitly stipulated in the terms of service (GTC) or client mandate agreement.

4. Value Added Tax (MWSTG), Place of Supply, and GeBüV Archiving

Invoicing must maintain strict compliance with Swiss tax and accounting legislation[cite: 2]:

  • Swiss VAT Compliance: Commercial consulting services are subject to the standard VAT rate of 8.1% under the Swiss Value Added Tax Act (MWSTG, SR 641.20) . Invoices must list the company UID number with MWST extension, tax amount, and applied rate[cite: 4].
  • Place of Supply for Cross-Border Clients (Art. 8 MWSTG): Consulting services delivered to foreign corporate clients apply the recipient-location principle (exempt from Swiss VAT, annotated as "Not taxable in Switzerland / Reverse Charge").
  • Audit-Proof Archiving under GeBüV: Under the Business Records Ordinance (GeBüV, SR 221.431) , all digital invoices, vouchers, and payment receipts must be preserved immutably for 10 years[cite: 4].
