The webshop software currently used is not very advanced as it is more than 10years old.
And since we found no webshop software on the market which offered all the things we wanted and which software could handle everything automatically,
we asked a software developer company to develop a webshop software with the things which we thought about.
Unfortunately they did not take the job serious enough and could not complete the development in 12 months, so we had to finally open contract and were left without a new webshop software.
Currently we still keep looking for a suitable software which will fullfill all of the special requirements we have... it is not as easy as you may think, because if we will change webshop software and so the order handling procedures then we want to get a kind of a "final" solution not only half solutions, so our requirements from the webshop software is kind of high and as said non of the commercially available webshop softwares which we looked at so far (and we've checked lots of) have all the functions we need, so we still looking for the solution. If we will find it then the order procedure will become more comfortable and our job easier.
