Presently the EC sales list can only be submitted to HMRC website through KashFlow at the same time as the VAT submission. However if there is an error (with the gateway, for example, as I have experienced) there is no function to allow the EC sales list to be submitted through KashFlow - I need to submit manually on the HMRC site. So to be able to check the amended credentials entered into KashFlow I now need to wait for my next VAT submission. It would be really useful if we could do this separately so we can be clear that credentials are valid - if not this can be validated before the next VAT submission.
