I would personally approach this a bit differently, particularly if you are VAT registered. If your interaction with the customers is all through the booking software then you don’t necessarily need to record every booking as an individual sale in QuickFile, you could turn off the Stripe feed and then just make one invoice each day with the daily total from the booking software, mark that as paid into your stripe merchant account in QuickFile, and mark the settlement payments you receive from Stripe into your current account as “bank transfer” between the two accounts.
This (deliberately) does not account for the Stripe fees, and the balance of your Stripe merchant account will gradually drift upwards during the month as the fees accumulate. A few days into the next month, Stripe will issue you with an invoice for the previous month’s total fees (under “business settings” → “documents” in your Stripe dashboard), and at that point you can create a single purchase in QuickFile from the Stripe invoice and mark it as paid from the merchant account.
This is definitely the best approach if you’re VAT registered, since the monthly Stripe invoice needs to be “reverse charged” on your VAT return - there are plenty of other posts explaining this process (e.g. EU Invoice reverse charging for purchase of services - #2 by ian_roberts), it’s not as simple as it should be unfortunately as QuickFile doesn’t support the reverse charge procedure, so you need to make a manual adjustment to your VAT return.
