Merchant custody risk
Collected VAT can remain mixed with business funds before remittance.
The structural problem
The taxable event happens now. Fiscal control often arrives later.
Traditional VAT models create a time gap between payment, merchant custody, declaration, remittance, reconciliation and audit. That gap is where leakage, cost and uncertainty accumulate.

The delayed-control chain
A system that observes after the fact cannot control the event while it is happening.
Administrative burden
Businesses and authorities repeat filing, matching, correction and follow-up work.
Revenue leakage
The delay creates room for under-reporting, non-remittance and fraudulent adjustments.
Evidence fragmentation
Payment, invoice, tax and settlement records may not form one coherent chain.
One transaction. Multiple delayed controls.
Sale→Merchant Holds VAT→Files Later→Remits Later→Audit Later
The longer the control gap remains open, the larger the operational and fiscal exposure.
