Even these systems aren't 100% and can't take into account human area, the system may say there are 40 gas cookers in stock but you only need one human to drop the pallet off the forklift and wipe the stock out.
Quote of the century! So true, that has happened to many companies in the past. Did you see the Youtube Video of the forklift driver who takes out the entire warehouse?

Yeah, Pitkin hits the nail on the head with his comment i think. To link a shop's EPOS to the website is an overhaul, we had the same issue so now we split the stocks apart. Originally, when we linked them onto one EPOS, it was never a live system, it used to update at the end of every day, what use is that? You could sell all your supply in one day if everyone else is sold out. That was Actinic, which i think is useless, never look to use that software if you are selling online or instore for various reasons.
There are live systems readily available that have live databases for free, we use one ourselves now and it works well, the problem is that you still need someone with the IT knowledge to put it together and maintain it. But if you can, it works beautifully. Problem is these people cost money! Modern stock issues often come from when you are selling on Amazon, Play and Ebay, you can never integrate all the systems into one and that is what causes EPOS errors constantly.
Sometimes customers forget that the outdoor trade is a really small industry, and most companies are focused at one area of that specific industry. Example being that we are mainly involved in the family camping aspect of the outdoor trade. Therefore to have that kind of money to put the perfect system in place for such a seasonal business is simply not possible. With the exception of maybe a few in the trade, not many companies could afford such expensive systems.
Plus most businesses seem to have a few websites now which means linking them gets harder as you cant have the same database on two websites with the same info or Google might penalise your site and drop your rankings.
I think Communication is the most important thing, as Rex says, its best to phone just to be sure the item is in stock if you are concerned.
