Why window fitters choose uno

Window fitting, glazing, and conservatory installation involve higher-value jobs - often running into thousands of pounds. The traditional model of invoicing after completion and waiting for bank transfers ties up your cash flow and creates chasing work you shouldn’t have to do.

A portable card machine means you take a deposit when you quote and the balance when you finish. Card in hand, payment processed, move on to the next job.

On-site payments

The Dojo PAX A920 connects over 4G and fits in your van. Take payment at the customer’s property - deposits when quoting, stage payments during longer jobs, or the full balance on completion.

Deposits and stage payments

For larger jobs, taking a deposit by card when the customer commits gives you security and them a receipt. Stage payments for multi-day installations keep your cash flow healthy throughout the project.

Over-the-phone payments

Customers who want to pay a deposit or settle a balance over the phone can do so through the terminal’s over-the-phone payment function. No bank transfer delays, no cheque clearing times.

Rates on higher values

On a £2,000 conservatory installation, the difference between 1.0% and 1.69% is nearly £14. Over a month of jobs, that’s significant. We compare providers to find the rate that works for your typical job values.

Showroom or trade counter

If you run a showroom or trade counter alongside your fitting work, the Shift4 PAX A800 handles walk-in sales and counter payments on a wired connection.

Common questions from window fitting owners

Can I take payment at the customer's property after installation?

Yes. The portable PAX A920 connects via 4G - take payment at the door, in the driveway, or wherever the customer is. Job finished, card tapped, payment done. No invoicing, no chasing transfers, no 'the cheque is in the post'.

Can I take a card deposit when the customer signs up for new windows?

Yes. Process the deposit at the customer's home during the sales visit, or over the phone after they've confirmed. Stage payments during the installation and the final balance on completion - all through the same terminal.

I currently invoice clients and chase bank transfers - would a card machine be faster?

Dramatically faster. Instead of sending an invoice, waiting for a transfer, and following up when it doesn't arrive, you take card payment on the spot. Job done, payment done, move on. Most mobile businesses that switch to card payment see their average time-to-payment drop from days to seconds.

A full house of windows costs £3,000–£8,000 - are the rates competitive?

On a £5,000 installation, the difference between 1.25% (£62.50) and 1.69% (£84.50) is £22. On one job. Over a month of installations, the rate difference adds up to hundreds of pounds. For window fitters doing regular high-value work, choosing the right provider rate is one of the easiest ways to protect your margin.

General questions about uno
Which card machine is right for my business?

It really does depend on how your business operates - there's no one 'best solution' for all, as a Fine Dining restaurant in Covent Garden has completely different operational requirements to a Market Trader in Glasgow's bustling Barras, or a Cardiff Arms Park pub. We make the effort to truly understand how your business actually operates - before recommending the best solution from a range of providers, not just one.

How much does a card machine cost?

It varies by provider and model. With some providers, your first card machine comes with no upfront cost, no monthly rental, and no per-transaction fees - so your only cost is the processing rate on each sale you make. Additional terminals - or those from other providers - may well carry rental or per-transaction fees. The exact cost depends on your terminal type, provider, and monthly card turnover. Because uno works across multiple providers, we compare the real-world, overall costs and then find the most competitive deal for your specific situation.

How long will it take for me to receive my takings?

We know for many UK independent buinesses cashflow is a daily struggle. We can offer various options, with settlement times ranging from just a few hours, to the full three days it takes providers to actually receive your customers money. Whatever your working requirements are, we'll find the ideal solution to match those needs.

Do all uno card machines accept contactless payments?

Yes. Every payment terminal we recommend accepts contactless payments, including Apple Pay, Google Pay, and standard contactless cards. Contactless is now the default way most customers pay in the UK.

Will I be able to take 'over-the-phone' payments?

For most merchant-types this will be offered as a default payment option, available on-screen along with contactless and Chip'n'Pin. There are a small number of exceptional businesess operational-types where this is not the case - but for most, 'over-the-phone' payments will be offered as standard.

How can we process refunds?

Any terminal uno suggests would allow you to easily identify the original transaction. If still within the same day as the sale, then the transaction could then be 'voided'(aka 'reversed'). Voids/Reverses are typically instantaneous. However, if that trading day's 'banking window' had closed (typically at Midnight) then it would technically be classed as a 'refund' - which would be subject to the bank's standard 3-5 processing timeframe to complete.

Will we need to do complicated PCI compliance like we do with our current provider?

The great news for you is none of the providers uno works with have complicated anything! For those that require PCI of any sort atall, it really is a simple, painless process that just takes a few minutes per year!

Am I locked into a contract?

Not with every provider. Several of the solutions we offer have no long-term contract - you can switch or cancel without penalty. We'll always be upfront about contract terms before suggesting you commit to anything.

How long does it take to get set up?

Most businesses are up and running within a few days. We handle the supply, installation, and configuration so you can focus on serving your customers. We walk you through everything on-site - so you're confident from day one.

Why go through uno instead of going direct to a provider?

Going direct means you only see a single provider's products, at a single provider's prices. Because uno works across multiple providers, we can genuinely compare options and recommend the solution that suits your business - not just the only one we happen to sell! You also get a dedicated point of contact for ongoing support.

Ready to find the right card machine?

We make the effort to your business, understand how you take payments, and recommend the solution that genuinely fits - not the one with the biggest commission.
