Digital sellers face a unique problem: once you hand over a file or account, you cannot take it back. That is why chargebacks and "I never received it" claims hurt digital sellers the most.
Escrow flips this in your favor. The buyer funds the deal upfront, so you know the money is really there before you deliver. You submit proof of delivery, and once the buyer confirms, the funds are released to you — no chargeback risk.
Add an e-signed contract describing exactly what is being sold, and disputes become rare. When they do happen, the contract and delivery proof protect you.
