Oh and a little bit of extra information on the 4 systems, 2 of them are point of sale based data and 2 are from post POS settlement/adjustment software. Ideally the POS software would always be correct because POS operators would always do their job and void/refund excess tickets however reality is different and it is easier to make adjustments to ticket sales in the settlement/adjustment software. So when all of this data goes into the warehouse it will be POS Sales/Refunds + Adjustments = Bottom Line which should then match to our separate accounting software.
