The VAT layer: the platform did it

For app-store and marketplace sales to consumers, the platform typically acts as deemed supplier: it charges and remits the consumer’s local VAT, and your supply to the platform runs B2B — reverse-charged, clean. Direct sales from your own site take the OSS route instead: that system. The mapping per revenue stream — store, direct, ads, in-app — is a one-afternoon exercise that prevents years of double-counting.

The income layer: one home

All streams land as business profit in the BV at 19% to €200,000 — and the technology’s share can ride the 9% innovation box: the box. Foreign platform payouts occasionally arrive with source-country withholding attached; the treaty network claims it back or credits it — the US chapter being the frequent one: the treaty page.

The planning layer

Holding above the app BV from day one (the exit thesis: why it pays), the founder’s salary-and-borrowing levers tuned through the growth years (the founder-salary chapter), and the revenue map revisited each January as stores change their terms.
