I am new here, so I may have missed this discussion but I have looked for any similar answers before.
My business as a sole trader generates thousands of PayPal and online sales via a merchant provider. These all produce a CSV spreadsheet of the sales which include the required data for HMRC. This constitutes my outputs.
I make trade purchases from two suppliers one bills me monthly, the other bills me on a drop ship basis for about 100 items a quarter, again these are listed on a CSV spreadsheet.
I have left it too late to work out how to get mtd software to integrate with these spreadsheets.
Since the mtd software just extracts the 9 box figures to submit to hmrc I have submitted the info Into my mtd software as a couple of monthly and quarterly summing up purchase invoices and sales invoices. Since my sales are all retail and the customers don't require full vat invoices.
I have worked out my 9 box submission figures as per the old way, and I have checked the VAT return generated by my MTD software and they both match. Well there is s 2p difference but that's a mystery of round ups.
If I get a VAT inspection my records are all available as per the spreadsheet, but they don't support the 9 box return in the same way.
As there is no requirement for HMRC to directly interrogate the mtd software to inspect the source of the 9 box will this be a reasonable approach to comply with HMRC given my time limits.
I will work to ensure my data gets into a mtd software in the approved manner as soon as possible.
