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.
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.
A commercial invoice is typically used for exporting goods internationally. This commercial invoice template includes spaces for the names of the individuals or businesses involved in the transaction, the items being shipped, where the items were manufactured, and Harmonized System (HS) codes for the items. This is essentially a customs declaration stating the value of the goods being shipped.
Back in the days before e-commerce, every job was billed using paper invoices, everyone was paid with paper checks, and all those paper records were delivered in person or sent in the mail. Back then it was easy to put together the information needed for an invoice. For the self-employed freelancer in the 21st century, things are no longer that simple and it affects what you put on your personalized invoices.
