Financial accounts preparation and submission to HMRC and Companies House

General information for the business: Small Bookkeeping and Accountancy Practice
Description of support work: I currently have around 50 limited company clients. I would like financial accounts drawn up for approval, and the accounts to be submitted to HMRC and Companies House for each of these.

I will provide either:

Sage backup or
TB, previous year's accounts (if applicable) and a tax calculation.

All journals will be done and the tax calculation. You will not be responsible for the content although any backup information can be viewed at your request. This is merely a data input task onto software such as Iris.

I am looking for a price per set of accounts.

Thank you
