Frequently asked questions

Why do I need a job number on my invoice?

A job number links the invoice to your internal work order or production schedule. It helps you track costs and helps your customer match the invoice to their purchase order, reducing payment delays.

How do I handle sales tax on manufacturing invoices?

Many states exempt manufacturing equipment or materials used in production, but finished goods may be taxable. You should verify your customer's tax exemption certificate and state rules. This invoice allows you to note such exemptions.

Can I use this invoice for government contracts?

Yes, but you may need to add FAR-specific clauses and include your CAGE code and contract number. The invoice includes fields for these, but always review your contract's invoicing requirements.
