Hey, we have been having a strange problem with our Quickbooks POS ver 13 multi user installation in a club setup (4 machines). Customers have to recharge their accounts before ordering and the big problem we have is discrepancies between current and available balances. However,the sale transactions are posted in real time but the balances take seem time to synchronize(happens to a random member account irregularly ) and we have changed the LAN routers and cabling and the problem is still persisting. The charge to account is posted after some delays of a few hours. We have integrated the solution to Quickbooks premier for financial exchange. Our company file is 500MB big and the connectivity tool doesn't post any errors. The environment is available for remote access any time. Any pointers?
