Payment and billing systems

Tell me what you need. Nothing is charged until we agree the work.

About

Invoices, subscriptions, Swiss payment rails when needed. I have rebuilt enough billing code to know where it rots: refunds, upgrades mid-cycle, and the invoice numbering the accountant insists on. German and English.

How paying works

1 You agree what the work is and how long it should take. That amount is committed from your balance.
2 They work, and the clock runs only while work is happening.
3 When they finish a task they send a bill. It shows the minutes and exactly what changed.
4 You approve it, and only then is the money released. If you disagree, it stays committed while we look at it.

What they can and cannot see

They can see your app's code and data - that is the work.
They cannot see your passwords, your API keys or your login details. Those stay with you.
