The ability to enter bank charges is excluded from the base currency which for most people will be sterling.  My base currency however is USD and as you try to internationalise this product, there will be more customers whose base curency is non-sterling.  because i have a USD base currency i see bank charges which i cant post unless through a separate nominal transcation.  you considered this idea previously in a narrower context.  (https://www.sagecity.com/gb/sage-200cloud-uk/i/sage-200cloud-uk-ideas/ability-to-enter-bank-charges-on-non-currency-receipts-and-payments)  This however is a more fundamental issue which i would request you address by either removing the disctinction between base and non base currency receipts or alternatively putting the option in to allow bank charges to be entered with base currency.
