Two EU VAT rules can make your platform the supplier — and they work differently.
Article 9a applies to e-services. Default position: your platform is the supplier. To rebut it, the underlying provider must be named in the contract and on the invoice, AND your platform must not authorise the payment, authorise the delivery, or set the terms. Any one of those three triggers — you are the supplier, on the full transaction value, not your commission.
Article 28 is broader — any service supplied in your own name on behalf of another. No presumption. The question is whether you act as principal in name while the substance belongs to someone else. Reseller, white-label, commissionaire — these are Article 28 patterns.
The error: treating them as interchangeable. 9a is narrower but presumes against you. 28 is broader but starts neutral.
