Just from recent experience, it is a bit of a pain in the ass to wind up a company. I recently started winding up a company about 3 months ago and the process has not completed yet. And my one was regarded as 'straightforward' because the business never traded, and all returns were up to date.
I used a company to handle the winding up arrangement, and it has cost me close to 700euro. However I didn't need to deal with the hassle. I'm sure your accountant could advise on a cheaper way of doing it but be advised it does take time, and at minimum will take a couple of months
