How to Collect Payment on Site as an Electrician

Every invoice you send and wait on is a receivable — money owed to you that you don't yet have. The longer that invoice sits unpaid, the more pressure on your cash flow. The simplest solution? Collect payment on the day, before you leave the site.

On-site payment for domestic jobs is increasingly the norm — most homeowners expect it and are set up for contactless payment or instant bank transfer. Asking for payment on the day is not rude or unprofessional. It's standard business practice, and most customers respect an electrician who runs a professional operation.

The benefits are obvious:

• No invoices outstanding — no time spent chasing
• No late payment risk
• Immediate cash flow impact
• Simpler bookkeeping — job done, invoice raised, payment received, all in one day

A card reader is the most frictionless way to collect payment on site. The customer taps their card or phone, and you get paid immediately (funds typically arrive the next working day).

SumUp

The most popular choice for UK tradespeople. The Air reader costs £29 (one-off) and takes 1.69% per transaction. No monthly fees. Works via Bluetooth with your phone. Simple to use and reliable. Funds next working day.

Square

Square reader is free (or £19 for the contactless version). Transaction fee is 1.75%. Square also offers a simple POS app with invoicing, customer records, and reporting — useful if you want one tool that handles both on-site payment and your invoicing.

Zettle by PayPal

Zettle reader at £29. Transaction fee 1.75%. Integrates with PayPal, which is useful if you already use PayPal for other business payments. Funds go to PayPal (instant) or your bank account (1–3 days).

Stripe Terminal

For businesses that want card payment integrated into their job management software (Jobber integrates with Stripe, for example). More setup but seamlessly connects payment to invoicing.

For most electricians, SumUp or Square is the pragmatic choice — low cost, simple setup, and works out of the box from day one.

Many domestic customers prefer bank transfer — they're used to it for paying bills and are often more comfortable with it than card payment. The advantage for you: no transaction fees. The disadvantage: requires the customer to initiate it on their banking app, which some find friction.

To make bank transfer work on site:

• Have your sort code and account number ready — on a business card, in your invoicing app, wherever is easiest to share. Don't make the customer type it from memory
• Use the Faster Payments system — bank transfers in the UK via Faster Payments settle in seconds. If the customer transfers on site, you can see the credit in your banking app immediately (if your bank supports instant balance updates)
• Use a payment reference — ask the customer to use your invoice number as the reference. This makes reconciliation trivial
• Show them the QR code or use Monzo/Revolut request link — some banking apps let you generate a payment request QR code that the customer scans. No typing required

Many electricians feel awkward asking for payment directly on completion. This discomfort usually comes from conflating "asking for money" with "being pushy" — but asking for payment for work you've done is entirely normal and professional.

Practical language:

• At quote stage: "Payment is due on completion. I accept card, bank transfer, or cash." This sets the expectation from the start
• At the end of the job: "That's everything done — I'll get the invoice sent to you now. Card payment is fine or I can take bank transfer if you prefer."
• For any hesitation: "If you'd like to pay by bank transfer, here are my details — you should be able to do it now from your banking app."

The key is to treat payment as a matter-of-fact part of the job completion process, not as a negotiation or favour. You've done the work; payment is what happens next.

Setting the expectation in your quote reduces any awkwardness considerably. A customer who's agreed to "payment on completion" in writing isn't surprised when you ask for it on the day.

Some customers can't pay on site — they're not the decision maker, the payment requires purchase order approval, or they simply don't have their banking details to hand. This is more common for commercial clients than domestic.

For these situations:

• Send the invoice immediately before you leave the property — don't wait until you get home
• Give the customer a clear, short due date: "Invoice is due within 7 days" is better than 14 or 30 for domestic clients
• For commercial clients where same-day payment is unusual, negotiate the shortest payment terms you can (14 days is better than 30)
• Follow your standard payment chase process — reminder on due date, phone call a few days later

The 80/20 rule applies: most of your cash flow improvement comes from on-site payment on domestic jobs. Getting that right frees up most of the time you currently spend on payment chasing.
