Duplie charges you a monthly fee for your plan. Starting at $10, you can't go wrong. You will be charged monthly for your plan. For any online payments you receive (donations, registrations), Duplie will charge a fee (1-3%) of the transaction -depending on your plan. When taking payments, you will need a merchant account to process your payments and deposit the funds into your account. They also charge fees (usually 2.9% and $.30 per transaction) to process the payments. So overall, you will likely pay around 5% + .30 per transaction. You can cancel your plan anytime and there are no minimums. If you need us to build/design a custom site for you or integrate your Duplie account into another vendor, we can provide an estimate. Before any work is done we will give you an estimated cost and agree on the effort involved.
