How to Invoice With a Credit Card Payment Button

PayPal
1. Send an invoice using Paypal. Customers who also have PayPal accounts or credit cards, can click on a link to make payment to your PayPal account.
2. Log-in to your Paypal account and select 'Request money' from the horizontal menu. Type in the email address of the recipient who you want to invoice.
3. Type any information required for the invoice, on the request payment page. Press 'Send.' Your customer will receive an email with a button for them to either sign-up for a PayPal account, or make their payment using a credit card.
Invoice Software
4. Create an invoice using accounting software that allows online payment acceptance. For example, QuickBooks has an option where you can click 'Invoice' and you can draft a customized invoice for your customer, which includes a payment button. Freshbooks, now linked with PayPal also allows you to create customizable invoices, which give the option to add a payment button.
5. Invoice yourself for a small amount of money, like one dollar, to ensure the button, link and money is going into the proper account. Email the invoice to yourself, and click the payment button. Sending a test invoice to yourself first, will make sure you do not have customers that are making payments to the wrong account.
6. Input your merchant account credentials in the fields provided in the invoicing software. For example, Fresh Books has a link to add PayPal to accept payments. You need to input your PayPal username and password here.QuickBooks has its own merchant account program that you register for. Once approved, you can include the payment button on the invoices you send.
