On 21st September, HMRC updated their list of software suppliers that have produced simple record keeping applications some of which meet cash basis and simplified expenses specifications following consultation with HM Revenue and Customs (HMRC). Many of these applications are free.
Please note that HMRC cannot recommend or endorse any one product or service over another and will not be responsible for any loss, damage, cost or expense in connection with using this software.
The current list can be found here.
