I have been using Additions Plus now for a year and I cannot rate them highly enough for their attention to detail and ability to make my life easier when dealing with my accounts. Raj and the team have been nothing but a delight to deal with. I thank them all for their advice and help along the way. No questions or tasks are too much, they work quickly and efficiently with everything they do. I can’t ask for anything more in help with my accounts.

Additions Plus Where the winning formula equates to the correct answer, All this collated from the a pile of invoices and receipts, resulting with them dealing with the appropriate company(s) with the frightening acromion like H.M.R.C & V.A.T. Leaving me stress free with the acromion that I understand at the end of the week, B.A.R & V.A.T.
