Question
Should we build a €39/month invoicing add-on for small studios?
02 / 07
Recommendation
Narrow the offer to payment follow-up and validate willingness to click and sign up before building invoicing.

Why now
A test costs far less than a build cycle and answers the pricing question directly.
