Field that adds a percentage

Hi,

We want to charge an additional 3% to businesses that are paying an invoice online with a credit card.

I want to set up a field that asks "Are you paying an Invoice?" If they choose yes, then 3% is added to the total due.

How should I set up this field?

Hi Christopher

Unfortunately, we don't support custom fee field with fee value calculated by percent

Maybe you can configure it using payment processing fee directly in payment method parameter (you can configure it by percent or by fixed amount). Look at os_paypal payment plugin for example to see that parameter

Configuring it at the payment level would not work as we only charge for invoices. Other payments are not charged the percentage.

Could this be a future feature?

Honestly, this is something quite difficult to add support for (since Payment Form support multiple fee fields, the fee fields itself will affect total payment fee, so no easy way for the system to get the amount which it needs to use to calculate by percent)

I will try to find a solution but this won't be available in near future

Regards,

Tuan

Hi. Has there been any progress towards this?

Sorry Christopher

We could not come up with a solution for this feature

OK. I figured out a solution.

1. Create a field that asks "Paying for Invoice?" with Yes or No options.
2. Adjust the default amount field to only show if "Paying for Invoice" is set to No
3. Create an invoice_amount field that will only show if "Paying for Invoice" is set to Yes. Set the Fee Formula to "[FIELD_VALUE]*.03+[FIELD_VALUE]" to charge 3%

This will adjust the amount to be charged.
