Network engineers send estimates before building a new network, replacing a firewall, deploying Wi-Fi, or migrating to new equipment. Clients often compare your quote against a managed service provider, a hardware reseller bundling installation, or another independent. They are usually comparing total cost, equipment choices, and how much downtime to expect.
When to use estimates: Use estimates to provide project quotes and get client approval before starting work. Once approved, convert your estimate to an invoice with one click to collect payment.

State the number of users, access points, switches, drops, and locations you priced for, since a change in any of them changes the labor.
Specify the make and model, whether you are buying it or the client is, and what happens if prices change or items are back-ordered.
Clarify whether structured cabling is included or handled by a separate cabling contractor, since it is a common source of delay and finger-pointing.
Say whether the work is during business hours or a maintenance window, and whether after-hours rates apply.
List subscription costs for security, cloud management, or support, and the term, so clients see the ongoing cost and not just the build.
Note that you assume working internet service, adequate power, a usable ISP handoff, and accessible equipment rooms. If those turn out to be wrong, it justifies a change order.
Name what is not included, such as server work, ISP troubleshooting, or end-user device setup, and the hourly rate for extra work.
| Service | Priced | Typical range |
|---|---|---|
| Remote troubleshooting and support | per hour | $90-175 |
| On-site network engineering | per hour | $120-200 |
| Emergency / after-hours support | per hour | $180-300 |
| Wireless site survey and Wi-Fi design | flat fee | $800-3,500 |
| Small office network build (firewall, switch, APs) | flat fee | $2,500-9,000 |
| Firewall / VPN configuration | flat fee | $600-2,500 |
| Network documentation and diagramming | per hour | $90-150 |
| Managed network monitoring and support | per month | $250-1,500 |
Typical US ranges. Rates vary by region, experience, and job size.
Undocumented networks, unlabeled cabling, and missing credentials slow jobs down. Add 10 to 20 percent to the labor estimate for fixed-fee work, or do a paid assessment first and quote the build afterward.
This makes comparison with reseller bids easier and lets clients see what they are paying for. It also helps with sales tax handling, which may differ between hardware and services.
Presenting a basic option and a more redundant option, such as a single firewall versus a high-availability pair, lets the client choose based on budget and downtime tolerance without you guessing.
Equipment pricing and availability change quickly. A 14 to 30 day expiration protects you from honoring a price that no longer works.
For anything beyond a simple office, yes. A paid assessment covers your time and produces a more accurate quote. Many engineers credit the fee toward the project if the client moves forward.
Detailed enough that the client knows what is included and what is not. List phases, equipment, licenses, and assumptions. A single lump sum with no breakdown tends to cause disputes when the scope shifts.
Yes. This works well when the environment is unclear. You bill actual hours up to a cap, and the client gets a ceiling on cost. Say clearly that going beyond the cap requires written approval.
Quote labor only and state that you are not responsible for the hardware selection, delivery timing, or warranty. Ask for the model list in advance so you can confirm compatibility and price the configuration time accurately.
