Cause of death: the autopsy

Marketplaces issue the withholding slips and the tax office pre-fills them into each seller's return. What is left is a free one-page letter, and Shopee hosts the template. The start date moved 4 times, Stripe can't take QRIS payments, and the farm had already rated it 13/25 on 10-04. Rescored from 17 to 12 out of 25.

The numbers

None. It was never built, so there are no visitors, sales or ad spend to count. It died on paper, which is the cheapest place to die.

Could rise again if

The report left no way back.
