Hi @damien82
Ideally, you should have one purchase invoice for each receipt for auditing purposes.
That said, it may be possible to merge some of these together if they’re the same supplier and the same date. For example, if you have 2 invoices given to you by the same company for design, and one for print, it may be possible to merge those two and tag the 2 receipts/invoices to one purchase invoice. This could even be done if there’s a few days difference (providing it doesn’t cross two accounting or VAT periods).
At the end of it, you should consider if HMRC were to ask you to prove a particular purchase, could you easily find it?
If you have many purchases, perhaps the bulk purchase input would make it easier for you? That way, it would be a simple enter price and click to confirm. There’s more information on this here.
