Take credit card payments without a card reader

How it works

1. Make the invoice. From the finished job, or in a minute by hand: who it's for, what for and how much. It's numbered for you.
2. Send it, or show the code. By text, email or WhatsApp, or as a QR code on your screen in the driveway.
3. They tap Pay. Visa, Mastercard, American Express, Apple Pay or Google Pay, on Stripe's secure page, on their own phone.
4. It's paid. It marks itself paid in Money, the receipt is ready, and Stripe pays the money into your bank account.

Your customer uses their own phone, so there's nothing to buy, charge or pair. If they're out, the link works whenever they get round to it.

What it costs

Knockround is $24.99 a month or $249 a year, after 7 days free with no credit card needed, and it adds nothing to card payments. Stripe takes its fee from each payment. Its published rates in the US, checked on 8 November 2026:

So a $250 job paid with a US card costs $7.55 in fees and leaves you $242.45. The card fee calculator works out any amount. Source: stripe.com/us/pricing.

Do you need a card reader?

Not with Knockround. A card reader works when the customer is standing in front of you with their card. A payment link or QR code works then too, and also when they're not home: they pay from the message later, and you don't drive back to collect.

Knockround doesn't turn your phone into a reader for tapping cards (Tap to Pay). Keep a reader as well if some customers would rather tap a card.

Setting it up

Sign up, then connect Stripe from the app in about five minutes. Stripe asks for your details, your bank account and your tax ID (your Social Security number, or an EIN for a business), as it does for every business it pays out to. Sole proprietors and LLCs both work. The money goes to your own Stripe account, then to your bank: every day, every Friday, or when you press Withdraw.

Cash and checks still work alongside cards. Take them as you always have and tick them off in Money, so the list of who owes you stays right.

Made for work at people's homes

Electricians and plumbers send the invoice from the truck when the job's done. Cleaners and lawn care crews send it to the customers who weren't home and show the QR code to the ones who were. See how it fits electricians, plumbers, roofers, handymen, cleaning businesses, lawn care and every other trade.
