Usually, order forms are created to offer services or products at a fixed amount. There is, however, a way to allow users to specify the amount of money they want to pay you. This is effective for businesses which require a prepayment, such as a copywriting firm. It’s also beneficial for churches and fundraisers to create donation forms and receive contributions online via a payment gateway.Here is how you can allow users to specify the amount of money they want to pay or donate on your online form:
1. Add a Number field in your Form Editor for your form users to add the amount they want to pay or donate for your services. Use this field to make sure users won’t submit invalid values(e.g. characters or symbols) which will not be recognized by your payment processor .
2. Then, in the Settings → Payments section of your form, assign to the value “1” to that number field. Next, go to Summary and Discounts and create a calculation formula by multiplying the Number field with 1 (from the Quantity column). For example:Amount X 1.
3. Save the settings. Now, the amount charged will be the one specified by users in the Number field.
