Business internet comparison: what to check in quotes

Two quotes land on your desk. Both are for "business internet", both quote a headline speed, and one is cheaper. Almost everything that will decide whether you regret the choice is missing from both documents.

This page is about closing that gap: what to ask so the two offers describe the same thing, and which differences actually change your working day. The overview is business internet.

What to take away

The headline speed is the least useful number on the page

Download speed is the number that gets advertised because it is easy to market and easy to hit in a demonstration. It matters when you are pulling something large: a big file, a software image, a video download. For most of what a small office does all day, it is close to irrelevant.

A voice call is a small, steady stream of packets. A video meeting is a slightly larger one. Neither is limited by how fast you could download a film. They are limited by whether that steady stream arrives on time, in order, and complete.

A connection can pass a speed test convincingly and still carry calls that break up, because the speed test measures the one thing the call does not depend on. What a call needs instead is set out in voip systems.

The numbers that decide whether calls and video work

Four properties matter more than the headline figure. Ask about all four, and

Latency is the round-trip delay. High latency does not sound like "slowness" on a call; it sounds like people talking over each other, because each side starts speaking before the other's audio has arrived.

Jitter is the variation in that delay. Steady delay can be smoothed over. Delay that swings around cannot, and the receiving end has to choose between adding more buffer, more lag, or dropping the late packets. Jitter is the usual culprit behind audio that sounds robotic or clipped.

Packet loss is the share of packets that never arrive. A download recovers from loss invisibly by asking again. A live call cannot ask again; the moment has passed. Loss far too small to notice on a file transfer is enough to make a call unpleasant. Finding where it happens is business internet troubleshooting.

Upload capacity is the direction almost everyone under-buys. If you host meetings rather than just attending them, your camera and microphone go up. If you back up offsite, that goes up. If customers reach a system you run in-house, that goes up. A connection with a large download figure and a small upload figure will feel fine when you are reading and terrible when you are being seen and heard.

Do not accept invented thresholds for any of these, including from this page. The platform you use for calls publishes its own network requirements; take target numbers from that documentation and hold the connection to those.

For turning a list of activities into a rough requirement, the Federal Communications Commission (FCC)'s broadband speed guide and household broadband guide are a fair starting point. The arithmetic of simultaneous use transfers directly to an office.

Shared service and dedicated circuits are different products

A consumer-grade service is shared. Capacity is pooled across everyone on the

same part of the network, and your experience moves with your neighbors' behavior. That is why a connection that was perfect at ten in the morning is a different connection at four in the afternoon.

A dedicated circuit reserves capacity for you. The same figure means something stronger: it is the capacity you get, not the capacity you might get. Upload usually matches download, the service is normally monitored rather than waiting for you to report a fault, and it comes with contractual commitments. Dedicated capacity is most often available over fiber internet.

Neither is automatically right. The honest question is what a bad hour costs you. If a degraded afternoon means slower email, shared service is a reasonable economy. If it means a contact center that cannot take calls, you are buying predictability, and that is what the price difference buys.

What a service level agreement actually commits to

An SLA is worth reading in full, because two of them can quote similar-sounding

Check what is being measured. Availability of the circuit is not the same as availability of the service you use over it, and planned maintenance windows are usually excluded from the calculation.

Check how a fault clock starts. It generally starts when you report a fault through the specified channel, not when the fault began. If you find out at nine on Monday about a failure that started on Saturday, the weekend may not count.

Check if the target restoration time is a target or a commitment with consequences, and check the remedy.

In most agreements, it is a bill credit, often capped and payable only if you claim within a stated window.

That credit compensates for service you did not receive, not for the trade you lost while the line was down. If the downside of an outage is much larger than your monthly bill, and for most businesses it is, the SLA is not your protection. A second, independent connection is. A radio path such as fixed wireless fails for different reasons than a buried one.

Making two quotes comparable

Work through these before you compare anything. Each one can flip which offer

Use this as a side-by-side worksheet: copy the exact written answer and quoted figure for each offer. Mark anything missing as unconfirmed rather than assuming it is included.

Before you sign

Ask what happens on the day the primary connection fails: does anything switch

over automatically, how long does that take, what stops working during the switch, and how would you know. A failover arrangement nobody has tested is a plan, not a facility.

Ask the installation question early and in writing, because lead time is set by physical work: permissions, access, and whatever has to be built between the network and your building, and it does not compress because your lease does.

And write down, before the quotes arrive, which two or three properties you are actually buying. It is much harder to talk yourself into the wrong connection when the criteria were fixed before the prices were. How the commercial side is structured is in business internet pricing.

Common questions

Is a dedicated circuit worth the difference?

It depends entirely on what a bad afternoon costs you. Price that first, then look at the gap between the two quotes.

Can we ask for latency and loss to be committed?

You can ask. Some providers will commit, most will not on a shared service, and the answer itself tells you which product you are being sold.

What if the address is shared with other customers?

Then inbound connections will not reach you, which breaks remote access and some phone configurations. Ask before you sign, not after.

How much upload do we need?

Count the people who will be seen and heard at the same time, add anything that backs up during the day, and use the platform's own published figure per stream.
