Does anyone have any experience with J&P Accountants?

They have offered me VAT filing in all 7 EU countries for €2000 (€1800 the year after) I currently pay around €2700 per year.

It sounds too good to be true, their reviews on Google/Trust Pilot are bad, but this is often the case with accounting firms

Be cautious about the low-cost VAT filing offer from a firm with bad reviews. Ensure they have a solid track record and consider seeking other reputable options.
