Save with money. Account and payments.
Since the beginning, we have relied on PostFinance as a very reliable partner. Technically and functionally they are always at the forefront, the user portal is great and also offers good tools for software companies in the background.
The services are (really) down from time to time. But that's part and parcel of innovating and trying out new things!
Realistic conclusion: Absolutely recommended.
