Most stacks get the order into NetSuite well enough. The gap opens after that: the payout arrives as one netted number, and unless every fee, refund, reserve, and tax line is decomposed onto the right GL account, the cash that hit the bank cannot be explained. The common workaround (sweep the unmatched line into a clearing account and promise to explain it later) is exactly how the unexplained difference compounds until the close cannot tie.
That is the line Altura owns. Vista Recon decomposes each settlement deterministically, foots it to the deposit, isolates the fees and timing gaps, and routes a genuinely new code to a person, never to a clearing account. The orders, and the money.
