There are some features that I think should be added (hint hint , such as:

1. Send invoices as a PDF attachment / Print invoices in PDF. Also send receipts as a PDF attachment.

2. Conditional prices based on quantity. For example example, if a customer orders between 1-5 of unit x, the cost is $2/unit. But if they order 6-10, the cost is $1/unit. So we could add these conditions, and then just enter the amount customer ordered and the system would calculate correct price.

3. Change the default e-mail subject and not have to change it each time.

4. Generate a statement for the client so they can see an overview of all invoice #’s, amount for the invoices, dates, and even maybe method of payment (and check # if a check was used).

5. Shorten URL.

6. Maybe offer customers (at a premium charge), the ability to use their own URL. If my company is ABC, Inc. and my domain is abc.com, I could setup a CNAME in my host records that billing.abc.com would go to your website, but look like it’s still handled by us (exactly how google does the hosted email).

There’s other ideas I have.

I really love this service.

Thanks for providing it!
