Hello,

Currently Blesta will only invoice using the customer's account preferred currency.

My suggestion is to allow tying a recurring invoice to the package set currency. Not the account's set preferred currency.
This will allow for a customer's account to have multiple packages with different invoiced currencies.

== Suggested ability to configure currency via GUI: ==

1. [Admin] It should be implemented as a checkbox under "New Package" in /admin/packages/add/. This checkbox should be labeled "Invoice using selected currency. Override account default currency"

2. [Admin] Under Upgrade/Downgrade of clicking "Manage" to Edit Service under "/admin/clients/editservice/CLIENTID/SERVICEID/". Add checkbox "Invoice using selected currency. Override account default currency"

3. [Client] Under "Change Term" for a particular service. A checkbox on "/client/services/changeterm/SERVICEID" should be labeled "Invoice using selected currency. Override default currency"
   This should only be available to a customer if the client group allows for the customer to specify this.

== Examples of why this suggestion is needed: ==

[Example Scenario 1:]
-If a service is set to CAD but the customer's account preferred currency is USD.
-The invoice is generated by converting CAD to USD.

[Example Scenario 2:]

• Service 1: CAD
• Service 2: EUR
• Both services upon renewal are converted to USD

This forced account currency introduces the following issues:

• Forced Conversion Fees. When not required:

• Customer has PayPal business account with all the following currencies $1 USD / $100 EUR / $100 CAD. Customer is now forced to pay a conversion fee by paying a USD invoice, even though they have plenty of CAD/EUR.

[Example Scenario 3:]
Blesta ignores a service's static set package price:

1. Package has the following set prices:
   1 month = $1 USD
   1 month = $1 EUR
   1 month = $1 CAD
2. Customer chooses the $1 CAD option
3. Invoice generated converts $1 CAD to customer's preferred currency of USD. Total is now $0.74 USD (Instead of the advertised package price of $1 CAD).

I welcome any feedback comments or suggestions to improve this potential Blesta feature.
This would benefit Blesta towards better handling multiple currencies for single customer accounts.
