When you use OfficeClip to keep your customer, contacts, and project information then why not use the same software to create your invoices as well? The Invoice feature in Contact Management Software can create and send invoices to your customers. It directs the customers to a portal where they can manage all their invoices, and they can also pay online if you have a PayPal or Merchant account.
Figure: Invoice Creation
If you create paper invoices and then mail them, you will enjoy using OfficeClip for invoice creation. You can create both recurring and non-recurring invoices. Recurring invoices allow you to charge your customer every month using their credit card.
The invoice can be emailed to your customer or printed out in physical form. When your customer clicks on the link in the email, they are directed to a customer portal that will allow them to organize and pay their invoices. This results in minimal paper handling and fewer payment delays.
