Fees for Non profit organization: Are we able to charge our customers?

Hello, We are a non for profit organization in the community (Football and Cheerleading) and lots of parents have been asking us to accept cards (since nobody has cash nowadays). We thought square would be perfect however as an organization we cannot pay the fee's associated. Are we able to charge the parents a convience fee (the cost it costs us to accept)?

We are a not-for-profit organization that accepts donations and retail sales receipts from members and customers.  In both cases, we would like to have a feature that would allow the donor/customer to donate the processing fee for the transaction when they pay with a credit card.  I have been able to do this with other not-for-profit organiztions when paying with credit card.  There is a simple question at the end of the transaction that asks "Would you like to make an additional donation to cover the credit card processing fee for this transaction (i.e., 2.9% +.30)?"  There is a "yes" or "no" option.  When the customer/donor chooses "yes", the system automatically calculates the amount and adds it to the total amount charged.  

Is this available on Square?

Will there ever be an option to add Donation Button, where individuals can kindly pay the processing fees?  We are not a store but collect membership fees.  Many are willing to pay the square fees but there is no option, except under the tax section, which we do not deal with.

We are also a nonprofit that uses square. I would like to also request our donors to be able to pay the merchant fees if they choose. Some donors are happy to do it We are not sending an invoice, so we are unable to ask them ahead of time to add the fee. This feature is available with other merchants. We love using Square and would like to also have this feature.

Yeah same here or maybe the merchant fees need not be an arm and a leg!;)
