If it's a Ltd company and you take any kind of salary, they are doing RTI filings and have had to deal with the pensions regulator.LTD company
200-300 transaction per year, relatively high value
80% export, EU and worldwide
THey do get the job don and have helped me out in the past. I am happy to stay with them but feel they may be charging me 1-2k+ over the odds.
If the 200-300 is purely sales and purchases, there are also expense transactions to consider.
Depends how you send them the info if it's not cloud based.
If not cloud based, full listing of Sales and Purcases (2 spreadsheets is good) a csv download of the company bank/credit card/paypal or whatever statements means they are able to manipulate data rather than input it - obviously quicker and therefore cheaper but would be surprised if it brought it down by the amounts you've indicated.
Talk to them and ask if there is any way you can present the info to make their life easier and therefore less costly to you.
Just my thoughts.
Cheers
