If you've been installing CCTV for any length of time, you'll know that the technical side of a job is rarely what keeps you up at night. It's the cashflow.

A large commercial CCTV job can involve spending thousands of pounds on equipment weeks before you see a penny from the customer. If a couple of those jobs stack up at the same time — or if one customer delays sign-off — you can find yourself genuinely stretched, even when the order book looks healthy.

This guide is about the practical steps you can take to protect your cashflow on larger CCTV installations: how to structure your payment terms, when to order equipment, and how to make sure the money coming in stays ahead of the money going out.

Why cashflow catches installers out more than margins do

Most CCTV installers who run into financial trouble aren't running unprofitable jobs — they're running profitable jobs paid too late. The business is quoting well, winning work, and delivering good installs. But the timing between spending and being paid creates a gap that gradually becomes a problem.

According to Federation of Small Businesses data, late payment affects nearly half of small businesses in the UK at any given time, and the construction and trades sectors are among the worst affected. CCTV installers sit squarely in that category on commercial jobs.

The fix isn't complicated, but it does require you to be deliberate about it before the job starts — not after.

Set payment terms before anything else

Your payment structure should be agreed in writing before you place a single order for equipment. This sounds obvious, but plenty of installers skip it on jobs where they know the customer, or where the commercial relationship feels solid.

A typical structure for a mid-to-large CCTV installation might look like this:

• Deposit (30–50%): Payable on order confirmation, before any equipment is ordered

• Stage payment (30–40%): Payable on delivery of equipment to site, or at a defined milestone such as first-fix completion

• Final payment (20–30%): Payable on practical completion and sign-off

The exact percentages are negotiable depending on the customer and job size, but the principle matters: you should never start spending significant money on a job without money in from that customer first.

If you're producing a formal proposal — which you should be on any job above a few thousand pounds — our post on tender-ready CCTV proposals covers how to set out your spec, assumptions, and terms in a way that makes payment milestones clear and professional.

The deposit conversation — how to have it without losing the job

Some installers avoid asking for deposits because they're worried it'll cost them the work. In practice, established commercial customers expect it — particularly on larger jobs where the equipment bill is material.

Frame the deposit in terms of the equipment order: "We need to order your cameras and recorder ahead of the installation date to guarantee the kit is in and ready — we ask for a deposit to cover that order before we place it." Most customers understand that you're not a bank.

If a customer pushes back on a deposit for a job involving several thousand pounds of equipment, that's useful information about how they're likely to behave on final payment too.

Keep your deposit invoices simple and clear, reference the job clearly, and make sure your payment terms (e.g. 7 days) are stated explicitly. Don't assume "payment on invoice" means the same thing to your customer that it does to you.

Timing your equipment orders to protect cashflow

One of the most common cashflow mistakes on larger CCTV jobs is ordering all the equipment upfront before the deposit has cleared — often because the installer is concerned about delivery lead times.

A better approach is:

• Get the deposit paid and cleared before placing the order — not just received, but cleared

• Order only what's needed for the current phase if the job has multiple stages

• Talk to your supplier about lead times on specific products so you can plan your order timing accurately rather than ordering early out of anxiety

If you're working with an IP CCTV wholesaler that has most stock available for next-day delivery, you have more flexibility on timing than if you're sourcing from a slow-moving distributor. That delivery reliability matters when you're trying to align equipment arrival with your stage payment milestones.

Stage payments: what milestones make sense

The most common mistake with stage payments is making the milestone something vague — "halfway through the job" or "when main installation is done" — rather than something specific and verifiable.

Good milestones are ones that you and the customer can both look at and agree are either done or not done. On a CCTV job, that might be:

• First-fix complete (all cable runs done, cameras mounted and connected, no commissioning yet)

• Equipment delivered to site

• NVR and cameras online, feeds confirmed on monitor

• Remote access configured and demonstrated

• Final sign-off with customer review of recording

Tie each invoice to a specific milestone and issue it promptly when that milestone is reached. Don't wait until you're back in the office on Friday — send the invoice the same day.

Equipment ordering on multi-phase jobs

On larger jobs that are broken into phases — say, phase one covering one building and phase two covering a second area six weeks later — you should treat each phase as a separate cashflow event.

Order phase one equipment when phase one deposit is received. Order phase two equipment when phase two deposit is received. Don't let the customer's convenience of a single order subsidise your own exposure.

If you're sourcing NVRs wholesale, cameras, switches, and accessories separately, it also helps to have a reliable CCTV parts supplier where you know the stock is available and the delivery is predictable. Chasing multiple suppliers for components on a phased job adds admin and uncertainty that's easily avoided.

Credit accounts with your supplier — use them properly

If you're regularly ordering equipment for larger jobs, a trade credit account with your equipment supplier can be a genuinely useful tool — but only if you treat it correctly.

A credit account lets you order equipment for a job and have 30 days (or whatever your agreed terms are) to pay. The idea is that the customer's deposit funds the order, which arrives and gets installed, you invoice the next stage, that comes in within the credit period, and you pay your supplier from that. Everything cycles cleanly.

Where it goes wrong is when credit is used to paper over cashflow problems rather than manage timing. If you're routinely using credit-account availability to fund jobs where no deposit has been received, you're borrowing against future income — and that compounds.

You can apply for a credit account with FVS CCTV if you're an established installer, and it genuinely is a useful facility on larger jobs when managed properly.

The equipment spec is a cashflow document too

When you spec a job, the equipment list directly determines your outlay before sign-off. Speccing for eight cameras when six would genuinely cover the site isn't just over-engineering — it's tying up more of your own money.

Make sure every item on your spec earns its place. If you're using PoE switches, spec the right number of ports and wattage budget, not a bigger unit "just in case." The same goes for IP cameras, power supplies, and accessories.

A tight, accurate spec also helps when you're having the payment terms conversation — it's easier to justify a 40% deposit when the customer can see exactly what that money is covering.

For PoE planning in particular, take a look at both parts of our guide on PoE power budgeting for IP CCTV to make sure you're speccing what you actually need.

Retention — and what to do about it

On some commercial jobs — particularly those involving main contractors or larger property companies — you may be asked to accept a retention clause. This means a percentage of the final payment (often 5–10%) is withheld for a set period (often six months) as a guarantee against defects.

Retention is standard in construction and there are legitimate reasons for it, but it does affect your cashflow calculation. If a £30,000 CCTV job has a 5% retention over six months, that's £1,500 you won't see for half a year. Factor that in when you're pricing, and be aware of the admin burden of chasing retention releases.

Some customers will accept a retention bond — a form of insurance — in place of cash retention. It's worth exploring on larger jobs.

Setting up systems so this doesn't need constant attention

The installers who manage cashflow well aren't necessarily doing complicated things — they've just made the right habits the default:

• Deposit before order, without exception

• Invoice raised the same day a milestone is reached

• Payment terms stated clearly on every invoice (not just in the original contract)

• Outstanding invoices chased on day 8 if not paid, not day 30

• Credit account used for timing, not to cover gaps

It also helps to stay on top of what's changing in the wider environment — our post on changes in CCTV specs and compliance is a good example of the kind of thing that can create unexpected scope changes on jobs if not caught early, which then feeds into payment timeline disputes.

Where remote access is part of your deliverable, make sure it's covered explicitly in your payment terms — it's easy for "configure remote access" to become an open-ended commitment that delays final sign-off and your final payment.

FAQs

Q: Is it reasonable to ask for a 50% deposit on a large CCTV job? A: Yes — particularly where the equipment cost represents a significant proportion of the job value. It's standard practice, and commercial customers are generally familiar with it. Frame it in terms of the equipment order.

Q: What if a customer refuses to pay a deposit? A: Treat it as a signal. You could compromise on percentage, but you should never start a large order with zero deposit from a customer you haven't worked with before. If they refuse entirely, that's a red flag worth taking seriously.

Q: How do I handle a customer who delays signing off the final stage? A: Make sure your contract defines what "practical completion" means — ideally with specific criteria. If those criteria are met, the payment is due. Vague sign-off language is what turns final payment into an ongoing negotiation.

Q: Can I use a trade credit account to bridge the gap between ordering and the deposit arriving? A: In theory yes, but only if you're confident the deposit is coming quickly and securely. Don't use credit to fund orders where the deposit isn't confirmed in writing.

Q: How do I protect myself if a customer goes into administration mid-job? A: Retention of title clauses in your supply terms mean that uninstalled equipment you've delivered remains your property until paid for. Speak to a commercial solicitor about how to word your contracts if this is a concern.

Q: Should I include the cost of accessories in the deposit calculation? A: Yes. Cables, connectors, brackets, and power supplies all cost money upfront. A full equipment list — including all CCTV parts and accessories — should be the basis of your deposit figure, not just the cameras and recorder.
