What does a company network cost? The cost drivers

What a company network costs depends on six factors: the number of ports and sites, cabling in an existing building or a new build, the hardware class required, the redundancy needed, the scope of documentation and ongoing operation after installation. Each of these can shift the price considerably. A serious quote names them individually instead of throwing out a flat number – and it comes after a site visit, not over the phone.

How many connections and sites are actually involved?

The biggest cost driver is usually the sheer count: how many workstations, access points, cameras and other networked devices need to be connected, and how many sites are tied together. A single office floor with twenty workstations is a different scope than a production hall with distributed machine controls, a warehouse with cameras at every gate, and an office wing on top. As soon as several sites need to be linked over a shared connection, additional line items appear: leased lines or VPN links between sites, redundant internet connections, and the question of whether central services sit at one site or run distributed. Every one of these questions shifts the effort involved – which is why a serious calculation always starts with an accurate survey of the structure, not a price per square metre.

• Number of workstations, access points and networked devices (cameras, printers, terminals) per site
• Number of sites and whether they need to be linked over a shared connection
• Reserve for growth – extra ports and capacity that aren't used immediately but will foreseeably be needed
• Whether central services (server, firewall) are bundled at one site or run distributed

Cabling in an existing building or a new build

Whether cabling is run through an existing property or a shell building is one of the biggest differences in the calculation. In a new build, the routes are open, cables can be planned straight into walls and floors, and empty conduits for later expansion cost barely more while everything is already being laid. In an existing building, on the other hand, existing walls, ceilings, fire compartments and often protected building fabric determine how a cable can even be routed – sometimes cable trunking or under-plaster routing is enough, sometimes only a wireless solution remains because a wall structurally cannot be opened up. Whether ongoing operation has to continue while cabling work happens also matters: work outside business hours or done in stages is more effort than cabling an empty building.

Which hardware class is actually needed?

Not every switch, every access point and every firewall is built for every job. A device meant for home use and a device meant for professional round-the-clock operation differ in build quality, cooling, manageability and the ability to deliver diagnostics when something fails – that explains a large part of the price difference between seemingly similar products. How demanding the requirement is depends on the actual operation: a production environment with high load and little tolerance for downtime needs different hardware than an office with modest usage. The distinction between purchase price and service life matters here – cheaper devices that need replacing after a short time aren't necessarily the cheaper choice once you calculate over time.

• Load capacity and cooling built for round-the-clock operation, not occasional use
• Manageability: central configuration and monitoring instead of individual devices with no overview
• Room to expand for foreseeable growth, instead of buying right at the limit of current needs
• Vendor-neutral selection instead of being tied to a single distributor

How much redundancy does the operation actually need?

Redundancy means a single failure doesn't immediately bring down the whole operation – a second internet connection, a redundant power supply in the core switch, a mirrored firewall pair. Every one of these measures costs extra, but the payoff isn't the same everywhere: a production business where a network outage stops the line evaluates redundancy differently than a small office that can bridge a short outage if it has to. The decisive question before any calculation is therefore what an outage actually costs this specific operation – not what redundancy is theoretically possible. Anyone who skips that question ends up buying either more protection than they'll ever need, or too little when it matters.

Documentation and handover

Documentation is often overlooked in the calculation, but it's a real line item: a network diagram, an overview of the configuration, a list of credentials kept in a password vault. If it's maintained as work progresses, the extra effort is manageable. If it's produced afterwards, or – worse – never produced at all, the bill only shows up at the next outage or the next provider switch, when nobody can trace how the network was actually built.

What costs remain after installation

Installation isn't the end of the cost picture. After it come ongoing items: maintenance and updates for the hardware, a contact person for faults, possibly licence costs for firewall features or management software, and eventually the replacement of devices at the end of their service life. A quote that only shows the initial installation and leaves out what follows doesn't give the full picture – anyone making an investment decision should also ask what effort realistically continues in the years after installation.

Why the timing of your request affects the price

One factor that's rarely considered: when in the project the planning actually starts. If a network is only requested shortly before the desired move-in date, there's less time for a proper survey, lead times for certain hardware can't be absorbed any more, and decisions get made under pressure instead of being reviewed calmly. If planning starts early instead – alongside construction or renovation work, for instance – cabling and empty conduits can be integrated into the existing trades, which works out cheaper overall than a later intervention into finished walls. Whoever controls the timing of the first enquiry also has more influence over the price than it might seem at first glance. Anyone planning several IT projects at once should therefore not look at the network in isolation, but prioritise it together with the other investments.

How NDVDL plans, builds and runs your network

NDVDL doesn't quote a network price without a site visit. We come to your premises, go through rooms, cable routes and existing equipment, and clarify what an outage actually means for you. You then get a written proposal in which each of the six factors is visible as its own item – including ongoing operation after installation.

Once installed, we keep looking after the network: maintenance, updates, changes and documentation that belongs to you. You have one fixed contact who knows your network, and you know in advance which part of the cost is one-off and which is ongoing.
