About Synder

Synder reconciles every channel and processor into one ledger that ties to the bank – every fee, refund, payout, and chargeback matched to the order behind it. Everything downstream inherits that. Your close, your margin questions, and any AI you point at your finances all read the same numbers – and every one of them traces back to the transaction that produced it.
