So as the new year approaches plan ahead if you have to do any programming changes to your cash registers. Is your sales tax going up the first of the year? Maybe a new tax rate being applied so you will now have two rates? Does the date on your cash register roll over to the new year or do you have to program it?
The new year should not affect anything to do with cash registers interfaced with credit card or gift cards so should be good there. The new year may be bring new PCI concerns so check with your processor.
Make sure you can locate your programming manual and programming keys in case you do need to make some changes. Most cash register companies do charge a support fee when you call up to make tax programming changes or related items so don't be surprised.
