§04  questions

What controllers tend to ask first.

01Is BillSplitter compliant with Swiss accounting standards?

Yes. The engine follows accrual-principle requirements under OR Art. 958c, HGB §252 (German GAAP for subsidiaries), and IFRS 15. Splits are computed on a daily pro-rata basis, which is the conservative default accepted by KPMG, EY, PwC and Deloitte Switzerland.

02Where is my data stored?+

Nowhere. Every calculation runs locally in your browser. No network request leaves the page, no invoice data ever touches our servers. You can close the tab and no record remains.

03How are rounding differences handled?+

We compute with full precision internally and round only at display. Any sub-cent residual is absorbed into the final period so row totals sum exactly to the invoice amount — never ±0.01 off.

04Can I split quarterly, annually, or by fiscal year?+

All three. Toggle the grain switch (MONTH · QUARTER · YEAR). Fiscal years default to the calendar year but can be shifted to any start month in the full calculator.

05Do you support multi-line invoices and foreign currency?+

Multi-line, yes — add as many amounts as you need in the full calculator. FX is handled by storing the rate at invoice date and applying it consistently across all periods.

06How do I export results for my auditor?+

One click. PDF (signed audit trail with method disclosure), CSV (one row per period), or Excel (with a journal-entry sheet). Nothing is uploaded — the file is generated locally and downloaded.
