- Serial numbers
- Every laptop, monitor and printer has a serial number used for warranty and asset tagging. Printing serial numbers on invoices lets corporate buyers register warranty, tag assets and verify that the units delivered are the units billed.
- OEM part number / SKU
- A laptop's marketing name covers many configurations. The OEM part number confirms CPU, RAM, storage, operating system and keyboard layout, and is what OEM rebate claims are matched against.
- Warranty type and term
- One-year carry-in, three-year on-site and accidental damage cover sell at different prices. Stating the warranty on the invoice prevents disputes when a unit fails.
- End customer and deal registration
- Corporate deals carry special OEM pricing approved for a named end customer. Printing the deal registration or bid number on the invoice supports the back-end rebate from the OEM and its audit.
- Software and services lines
- Operating system licences, antivirus and installation or imaging services are separate supplies. Showing them on their own lines with their own code avoids classifying a service as hardware.
- Bundle reference
- Combo offers combine a keyboard, mouse or bag with a laptop. A bundle reference explains why some lines are at zero or reduced value.
- Delivery and installation address
- Corporate orders are delivered to branches in different states. The ship-to address decides place of supply and the e-way bill route.
