ComptaNexo helps Swiss freelancers, Sàrl and small SMEs get out of the spreadsheet without replacing their fiduciary. Quotes and Swiss QR invoices, expenses and receipts, VAT, payment tracking with CAMT bank reconciliation, and a structured export the accountant can actually pick up — in native CHF, with the data exportable at any time.
The product as a system
- Quote
- QR invoice
- Payment (CAMT)
- VAT
- Fiduciary export
The problem and the hard part
- The problem
- The problem is not the accounting — it is the state of the file before it: invoices in one tool, expenses in a folder, receipts as photos, payments checked by hand, VAT tracked in Excel, and the fiduciary chasing by e-mail.
- The hard part
- Being genuinely useful to the fiduciary without competing with it — the product stops at a clean, structured hand-off instead of trying to become the ledger.
- Not to be confused with
- ComptaNexo covers what a Swiss company invoices and gets paid — quotes, QR invoices, receivables, CAMT reconciliation, VAT. Neucelle covers what a restaurant spends in cash. Different side of the same accounting file.
What shipped
- Swiss QR-bill generation with a free public tool as the entry point — a real QR invoice before any account exists
- Recurring invoices, payment tracking and CAMT.053 bank reconciliation, so “paid / open / late” stops being a manual check
- VAT tracking with the Swiss rates and the TDFN method, carried through to the export rather than reconstructed at the close
- A fiduciary export built as the deliverable — invoices, expenses, notes and the VAT period as one structured file
- Programmatic search architecture across Swiss accounting intents: QR invoices, VAT thresholds, cantonal pages, Shopify/Stripe reconciliation, tool comparisons
