I would get another accountant pronto, let them do the wages and that stuff, why do it yourself when you can pay someone else to do it and have less stress.
If you are just starting out employing then paying A N other to do the wages is a waste of money.
It is so easy on line, just set up the employee details and each week you key in the date you paid them and how much gross. Answer a few tick box questions and push enter....it calculates any tax or NI due. You can also print off these details and us them as a wage slip.
You will also be e-mailed when the tax and ni payments are due to be paid to HMRC and at end of year you make your selection and it does it all for you.
If you were going into the realms of employing 10 or more then perhaps think about getting someone to do the wages, but in all honesty, if you have average keyboard skills then after a couple of weeks entering 10 lots of pay details should take no longer than half an hour
