Right now we have currencies £/EUR/$ set up on the site. The payment gateways we are using are Realex and PayPal.
Currently, even if you are in $ or EURO when purchasing, when the money is taken at checkout it reverts back to GBP. This is because it takes the base site currency.
Will the Multiple Store View Pricing extension enable us to pass the store view currencies ($/EURO/£) through into the relevant gateways (Realex and PayPal) as they have the correct accounts set up within their merchant accounts for those payment gateways so that is not the issue?
As our module's feature, you could set base currency for each store view and customers can checkout with base currency of their store view (buyer account).
However, if you means about merchant account (seller account), default Magento just allows there's one merchant ID (which is set up in payment method) for website: http://prntscr.com/f94rhg
And our module does not support to set it per store view.
