Invoice clients for network design, installation, and managed network services. Professional invoices from Tidybill.
A network engineer invoice covers work designing, installing, configuring, and maintaining network infrastructure including routers, switches, firewalls, wireless systems, and wide-area network (WAN) connections. Network engineers may work on LAN design for new offices, VPN setup for remote workers, network security hardening, SD-WAN deployment, or data centre networking. Hardware procurement is a significant part of many network projects, and invoices should clearly separate equipment costs from labour fees. Contract network engineers often work on a day rate for project-based installations or on monthly managed service contracts for ongoing network monitoring and support. Because network downtime has direct business impact, emergency response rates are a standard part of any network engineer's fee structure.
| Service | Typical Rate | Unit |
|---|---|---|
| Network engineering (day rate) | 550 | day |
| Network design and planning | 800 | project |
| Network installation (hardware + config) | 2000 | project |
| Firewall configuration and security hardening | 600 | project |
| VPN setup (site-to-site or remote access) | 500 | project |
| Monthly network monitoring and support | 400 | month |
For installation projects, separate hardware costs from labour on the invoice. Hardware should be listed at cost (or with agreed markup) on separate line items with model numbers and quantities. Labour should list the tasks performed and hours or days worked. For managed service contracts, invoice monthly with a summary of monitoring alerts addressed, uptime stats, and any configuration changes made.
