I would like to thank them for the professional accounting services provided for my business in Spain. Every task was resolved quickly and to a high standard, thanks to their attention to detail and high level of expertise. Perfectly organised bookkeeping, timely tax advice and attention to changes in the legislation — exactly what I was looking for. I recommend this company to anyone who needs a reliable accountant in Spain.

In Spain it's very hard for the Russian-speaking community to find a company you can trust, because almost everyone tries to cheat you and charge you more. But Asistenio SL is a godsend. First I was pleasantly surprised by the price of the services, which I think is the fairest around. Then I was struck by the fact that I was never forgotten for a second — they kept me constantly informed about the sale of my apartment in Benidorm. The peak of my surprise was that the company took on the litigation against the tax office, because my tax had been calculated incorrectly. I had never seen, or even heard, of that happening in practice anywhere. And the staff? Every one of them lovely, warm, smiling, kind, sincere and, without doubt, true professionals. Every time I went to the office I left in a good mood. Another important point: the price of the services never changed from what was quoted at the start. They have a clear, transparent price list — you simply choose what you need, instead of the usual situation where you agree one amount and end up paying another. Thank you so much. The only downside is that you don't work in Alicante. Wishing you every success!
