If your business ships products to customers, a sales invoice template is the perfect choice. This template allows you to include shipping information, and it calculates the tax along with shipping and handling. This is ideal for small business invoicing, looks professional, and coordinates with the packing slip and purchase order templates.
If you are shipping products, including a packing slip with the shipment provides clear communication to your customers. Indicate what items are included as well as any items that were ordered but not shipped. Not only does a packing slip inform customers, it can also help reduce mistakes before shipping. This is intended as an addition to a sales invoice.
Smartsheet is a spreadsheet-inspired work management tool with robust collaboration and communication features. Its Google Docs integration and pre-built invoice tracking templates make it even easier to manage customer information, create, send and track multiple invoices at once, and quickly organize the details.
Most businesses use the same sorts of information on invoices: contact information, sequential invoice numbers, etc. Because of the unique nature of freelance work compared to other businesses, especially for freelance invoices, it should be adapted to reflect these differences.
