It would be great if invoices could be more personalised with logos etc. And it would be great to be able to link an invoice (I’ve created independently) to an incoming payment.
The link would be handy but we’ve moved away from Monzo invoicing as it’s too limited.
Other software provides a much nicer customer and business solution at this time sadly.
Have a look at Xero if you only do small amounts of invoicing and use GoCardless and Stripe.
