Keeping everything under one PayPal account turns into an accounting nightmare once you’re selling across different platforms. You’re trying to figure out which payment came from where, reconciling everything manually, and the whole thing becomes a mess by the end of the month. PayPal’s terms technically allow business accounts and personal accounts, but they get twitchy about duplicate accounts under the same name or address. Some sellers try using slightly different business names or getting family members to open accounts, but that usually backfires when PayPal’s system flags the linked information. Stripe’s an alternative for some marketplaces, though not everywhere accepts it and you’re still dealing with similar restrictions.
