Fixed fee, tax included. Investors and funders welcome.

See what each service includes. Our engagement terms apply.

Nothing confidential is needed to pay.

After payment

Stripe emails your receipt. Then send your brief to team@osih.ch from the same address. Confidential files wait until any NDA is signed.

Already have a custom-work invoice?

Pay it through the Stripe link we emailed you, not here.

Something does not match?

Write to team@osih.ch before paying. Never send card details by email.
