Starting accurate inventory is a very complex and time consuming process and this must not be jumped into, and all ramifications must be understood before moving forward.
Questions to ask:
1. Will you be taking inventory on a regular period by retail, normally done by an outside company, monthly?
2. Will you be taking inventory on a regular period by SKU using the S2k hand held unit? Or will you be doing only spot checks on an item level?
3. Will you be using both methods and if so how?
Most companies cannot spend the time or resources to bring in and maintain invoices at an item level, for all items. Obviously if every item was invoiced using EDI/Emailed then we could that, but that is not possible in the C-Store business today. The overall solution is to take inventory on a Retail basis using an outside company once a month and then using the S2k handheld, and EDI invoices, spot check important items like Cigarettes, Haba, Lottery etc.
