A business is the entity for which you will collect income source documents. This entity could be a Sole Trader, Property Business, Partnership, Limited Company etc.

A client may have multiple businesses or properties, so if needed you can add additional businesses after the first entity is added.

Self employment: for a Sole Trader, Partnership, Limited Company etc.

Or UK Property: for a property businesses operating in the United Kingdom.

A transaction Collection Method is the type of documents you’ll be submitting to Dext, and will determine how you add transaction data to Dext. There are two collection method options:

  • Costs/Sales: add receipts and invoices to the costs & sales workspaces through various methods, including uploading items via the desktop or mobile app and via email.
  • Or Bank: add transaction data by connecting to a bank feed or uploading a bank statement. A bank feed will import historical transactions as far back as the bank will allow.

  1. If a client has multiple businesses or properties you can add another to their account by clicking Add another business.
  2. When you are finished adding a business or businesses, click Next.
  1. On the next page, review the email that will be sent to the client, and add the client’s mobile number if you wish to send them an invitation by text. When ready, click Invite to Dext.

Adding & Managing Income or Expenses

Add transaction data on behalf of your Dext Solo clients and categorise them into HMRC set codes. Categorised transactions can then be organised into reports on the reporting summaries page, in preparation for sending to HMRC.

How to Add Income & Expenses

Depending of the transaction collection method selected (costs/sales or bank) you will see several submission methods.

See this article for how to use the different submission methods to add transaction data.

Categorising Transactions

The list of codes you can use to categorise transactions is preset by HMRC, and depends on the type of business selected.

You can see a list of these categories by going to List in the sidebar, then Categories.

See this article for how to categories costs & sales items or bank transactions.

Splitting a Costs or Sales Item

It may be necessary to split out line items in a costs or sales item, for example to differentiate between business and personal expenses.

See this article for how to use line items to split a transaction.


The Reporting Summaries Page

The reporting summary page is where all of the client’s data is compiled and broken down by category.

You can filter the data by date in the top left of the screen and export it by clicking Export to CSV.

In the near future, you will be able to submit these reports directly to HMRC and export reports as CSVs.
