What usually goes wrong

Symptom	Likely cause	First thing to check	Who absorbs it
Payment shows "sent" but the supplier has no pesos	An off-ramp review, its bank refusing crypto-linked money, or a closed local rail	The off-ramp's status	The supplier's cash flow
Coins gone, supplier says nothing arrived	Wrong or look-alike address, or the wrong chain	The transaction against the allowlisted address and chain	The payer
The supplier's "new address" belonged to an attacker	A fake change-of-details email	How address changes are verified	The payer
Inbound coins can't move	Issuer freeze or sanctions block	The issuer's blocklist; the sending wallet's history	The recipient
Cost higher than quoted	Quote expired before funding; wire funding; a wide off-ramp spread	Quote expiry against funding time	The payer or the orchestrator, by contract
Unapplied cash at the supplier	No usable reference on the chain or the local credit	Reference mapping in the orchestrator's API	The supplier

Ranking these by frequency or cost needs an operator's data; I found none public.
