You can either send your e-bills from your financial software or use the online solutions e-bill light, SmartBusiness or ISRlight:

Integrated e-bill solution

Our integrated solution is ideal if you already have your own software and want to optimize payment collection. Issue your invoices in your software as usual. The invoice data is transferred to PostFinance from your system as a data file before being processed and forwarded to the recipient automatically in electronic format.

E-bill light

E-bill light is ideal if you only send a few invoices each year and do not have your own software. Registration and invoice recording are done online.

ISRlight

ISRlight is ideal for small and medium-sized enterprises that do not yet have their own software but want easy-to-use software for complete invoice processing.

SmartBusiness

Do your customers use e-finance? If so, you can issue and send your invoices very easily via SmartBusiness. The online platform helps you with everything from creating offers and invoicing to checking outstanding accounts receivable.

Value added tax

The revised VAT Ordinance (VATO) was introduced on 1 January 2018. Since then, the Swiss Code of Obligations (CO) and Accounts Ordinance (AccO) have applied to all documents, whether on paper or in electronic format. No provisions extending beyond general accounting principles apply to VAT.

The price depends on the number of e-bills sent and/or received per customer and per month.
