Buying an existing SMM panel means acquiring a business, not software. The domain, customer base, order history and revenue arrive as one listing, but their transferability is completely different. Screenshots are not proof of revenue; verification comes from payment processor statements, bank records, supplier spend and a live screen-share walkthrough. The panel may be running on a nulled script, merchant accounts almost never transfer to a new owner, and users holding wallet balances hand you a liability rather than an asset. Finish diligence before you pay, and stage the payment.
