You finished the job, packed the van, and said the four words that quietly cost trades a fortune: "I'll send an invoice." Two weeks later you are chasing it. The faster path is to accept card payments right there on the job, before you leave site, while the customer is happy and standing in front of you. This guide shows you how to get paid on the spot with a payment link the customer opens on their own phone, no card reader, no terminal, no awkward wait.
The trick is that you do not need a hardware card machine to take a card. Every Billr invoice already carries an online payment link and a hosted pay page. You hand the customer the invoice, they tap the link on their phone, and they pay by card through Stripe or with PayPal in under a minute. Billr marks the invoice paid automatically. Below is exactly how the field workflow runs, what it costs you to wait instead, and the backup payment methods for the customer who never carries a card.
The real cost of "I'll send an invoice"
Delayed payment is not a minor annoyance. It is the single biggest cash-flow killer in the trades, and it compounds quietly. Picture a typical week of work and the money that should already be in your account.
- The chase eats your evenings. A GBP 320 callout becomes a string of "just following up" texts. You are doing unpaid admin after a ten-hour day.
- Memory fades, disputes grow. The longer the gap between the work and the payment, the more a customer second-guesses the bill. Paid on the spot, while the new boiler is humming, there is nothing to argue about.
- You become the bank. Wait 30 days for a EUR 1,200 job and you have effectively lent that customer EUR 1,200, interest free, while you have already paid for the parts.
- Some never pay at all. A slice of every "I'll send an invoice" job turns into a write-off. Money you earned, gone, because the moment passed.
Getting paid the moment the work is signed off flips all of that. The cash is in motion before you start the engine. If chasing money is a recurring theme for you, our guide on how to get paid faster goes deeper on the habits that close the gap.
What "card payment on the job" actually means with Billr
Here is the important distinction, because it is easy to picture the wrong thing. Billr is not a physical card reader, a tap-to-pay terminal, or a POS device. You do not hold the customer's card or phone against your handset. There is no contactless tap on your end at all.
What Billr gives you is an online pay link and a hosted pay page. Every invoice you create automatically carries a payment link once you have connected Stripe or PayPal. The customer opens that link on their own phone, sees a clean page with your logo, your business name, the invoice number, and the total, and pays from there. No app to download. No account to create. No login.
Think of it as handing the customer a checkout, not swiping their card. They are in control of their own device and their own card details, which most customers actually prefer. And because the payment runs through Stripe (Visa, Mastercard, Amex) or PayPal, it is confirmed by a webhook and your invoice flips to Paid on its own. You do not mark anything manually. You can read more on the payments feature if you want the full picture of how confirmation works.
The field workflow, step by step
This is the part that matters: the actual choreography on site, from "all done" to "paid" in a couple of minutes. Say you have just rerouted a leaking waste pipe under a kitchen sink, a GBP 180 callout.
- Build the invoice on your phone. If you tracked the time with the timer, turn those hours straight into invoice lines. Otherwise drop in a saved service item from your catalog. Add parts, confirm the total, done. It takes under a minute.
- Hand the customer the invoice. You have three ways to do this, pick whatever suits the moment. Show the invoice on your own phone screen and let them tap the pay link. Send it by email. Or use native share to fire it straight into WhatsApp or any messaging app on your phone.
- They open the pay page on their phone. The link opens the hosted pay page, branded with your details. No login, no friction. They see the GBP 180 total and a Pay by card button (and a Pay with PayPal button if you enabled it).
- They pay. Card number, expiry, CVC, done. The page shows a live status: "Confirming payment," then "Invoice paid."
- Billr marks it paid for you. Stripe's webhook confirms the payment and the invoice status changes to Paid automatically, with the provider, amount, and reference recorded for your books. You are already pulling out of the drive.
Two minutes of phone work and the money is on its way, instead of two weeks of chasing. The customer never touches your phone, and you never touch their card.
Showing it on your screen vs sending the link
For a customer who is right there, the fastest move is often to send the invoice by WhatsApp or email so the pay link lands on their phone, then let them pay while you load the van. That way the payment lives in their messages, they have a copy of the invoice, and you are not standing over them. If they would rather sort it later that evening, the same link still works. The invoice is not a one-time offer that expires when you drive off.
Backup methods for the customer without a card to hand
Not everyone wants to type a card number standing in their hallway, and that is fine. The beauty of the link is that the same invoice offers more than one way to pay, so you never get stuck on "I haven't got my card on me."
- Bank transfer. Your bank details and payment instructions can be printed right on the invoice. A customer who prefers a transfer can do it from their banking app on the spot, using the invoice number as the reference.
- SEPA / QR code. For euro-area customers, Billr can put a scannable QR code on the invoice. They open their banking app's camera, scan the code, and the payment is pre-filled with your account and the amount. It is about as close to a tap as a bank transfer gets, and it is on-the-spot fast.
- PayPal. If the customer lives in PayPal, the pay page offers it as a one-tap option alongside card.
Between card, PayPal, bank transfer, and the QR code, almost any customer can settle up before you leave. If you are weighing which online provider to switch on first, our breakdown of Stripe versus PayPal for contractors compares fees and payout timing.
Why on-the-spot beats a card machine anyway
You might wonder why not just buy a physical card terminal. For plenty of trades, the pay-link approach is the better fit, and here is the honest reasoning.
- Nothing to carry or charge. No extra device in the van, no flat battery, no "the reader won't connect" moment in a basement with no signal.
- The customer has a record instantly. They pay against an actual invoice, not a faceless card tap, so they get a numbered, branded document for their own records and any warranty claim.
- It works when they are not home. Finished a job while the customer was at work? The same link goes to their phone and they pay from the office. A terminal needs the cardholder present.
- One tool, not three. The invoice, the payment, and the paid-status record all live in the same place, which keeps your invoicing clean and your books honest.
Make it routine, not a one-off
The trades who get paid on the spot do it because they decided to, not because the stars aligned. A few small habits turn it into your default.
- Quote the price clearly up front so the total on the pay page is no surprise. Nobody pays fast when they are shocked by the number.
- Build the invoice before you tidy up, while the customer is still relaxed and pleased with the work, not as an afterthought from the van.
- Ask plainly: "I'll send this over now, you can pay by card on your phone, takes a sec." Framing it as the normal way you work removes the awkwardness.
- Default to sending the link so the customer pays on their own device and keeps the copy. It is the smoothest version of the whole exchange.
FAQ
Do I need a card reader or terminal to accept card payments with Billr?
No. Billr is not a card reader, tap-to-pay terminal, or POS device. It gives every invoice an online pay link and a hosted pay page. The customer opens the link on their own phone and pays by card through Stripe or with PayPal. There is no hardware to buy or carry.
Does the customer need to download an app or create an account?
No. The pay page opens in any web browser with no login and no app. They just tap the link, see your branded invoice and the total, and pay. That is the whole point: zero friction for the person paying you.
How does the invoice get marked as paid?
Automatically. When the customer pays, Stripe or PayPal confirms it by webhook and Billr flips the invoice to Paid on its own, recording the provider, amount, and payment reference. You do not have to mark it manually.
What if the customer does not have a card on them?
The same invoice offers backups: bank transfer with your details printed on it, a scannable SEPA QR code for euro-area customers, and PayPal. They can settle by whichever method suits them, often straight from their banking app on the spot.
Can I take a card payment with no internet on site?
You can build the invoice fully offline, since Billr works without a connection and syncs when you reconnect. The card payment itself runs online through the pay page, so the customer needs a signal or their own mobile data to complete it. In a true no-signal spot, send the link and they pay the moment either of you is back online.
