How do I customize my company information for just a single invoice?

You can customize your company's contact information on a per invoice (and per estimate) basis. Here's how it works:

When creating/editing an invoice (or estimate) in Harpoon, click the "Customize" button at the top of the invoice.

This gives you the ability to overwrite some of your global default invoice settings for that invoice only, including your company's contact information.

This can come in handy if you have a single, taxable company that might be operating under more than one name. Or it could be as simple as wanting to funnel a certain client's calls to a unique phone number.
