Card-on-file & pre-authorisation for businesses

Card pre-authorisation,
simplified.

Send your customer a secure link. They enter their card — you save it on file or hold a specific amount. Three steps, no card details over the phone.

The problem

Taking card details over the phone is broken

Most booking-based businesses still guarantee reservations the same way they did 20 years ago — scribbling card numbers on paper, reading digits over the phone, or simply hoping customers show up and pay.

No-shows cost you money

You set aside time, staff, or resources — then the customer doesn't turn up and you have no way to recover the loss.

Card details over the phone aren't safe

Writing down numbers, reading them aloud, sending them by email — none of this is PCI compliant, and it puts you and your customers at risk.

Trust-based systems don't scale

When your business depends on hoping customers follow through, every booking is a gamble. One bad experience can wipe out a day's profit.

How it works

How it works

Add your customer, send them a link, and hold their card. That's it.

1

Create a client

Add your customer's name and how to reach them. Takes seconds.

2

Send a link

Your customer gets a secure link by email, SMS, or WhatsApp. They open it and enter their card details.

3

Save the card or hold an amount

Save their card for later, or put a hold on a specific amount now. Either way, you're covered before the job starts.

For your business

What pre-authorisation does for your business

Secure every booking, reduce no-shows, and protect against disputes — without changing how you run your business day-to-day.

Guaranteed bookings

Every booking is backed by a pre-authorised hold on the customer's card. If they don't show up or cancel late, you can capture the held amount to cover your losses.

No card data liability

You never see, store, or handle card numbers. Everything goes through your payment provider's secure checkout — so there's no PCI compliance burden on your end.

Secure bookings instantly

Send a link while you're on the phone, in a WhatsApp chat, or via SMS. Your customer saves their card or authorises a hold there and then — the booking is locked in.

Card on file for repeat customers

Save your customer's card once and use it whenever you need to. No chasing, no re-entering details — just charge the card on file when it's time to collect.

For your customers

A better experience for your customers

Your customers get a secure link, enter their card on their own device, and know exactly what they're authorising. No phone calls, no awkward card readings — just a checkout they can trust.

Card details stay private

No reading numbers over the phone or sending them by email. Customers enter their details on a secure, PCI-compliant checkout page. Your business never sees the full card number.

Full visibility over what's authorised

Customers see exactly what they're agreeing to before they confirm. They receive a receipt when their card is saved or a hold is placed — complete transparency at every step.

The standard they already expect

Instead of sharing card details over the phone, customers receive a secure link on their own device. It's the same checkout experience they're used to from any reputable online service.

Use cases

Built for businesses that book ahead

If you take bookings, reservations, or appointments — Pre-auth gives you a way to secure them. Here are a few examples.

Hotels & holiday lets

Hold a damage deposit on your guest's card before check-in. Release it at checkout when everything's fine, or capture it if there's an issue — no awkward conversations required.

Events & venues

Secure a booking deposit the moment a client confirms a date. If they cancel late, capture the held funds instead of chasing an invoice — your calendar, your terms.

Mobile & on-site services

Know payment is secured before you load your van. If a customer cancels last-minute or is a no-show, the held amount covers your wasted trip — no more working for free.

Rentals & equipment hire

Take a security deposit without charging upfront. Release it when the item comes back — or capture if there's damage. No card details handled by you.

Pricing

Simple, transparent pricing

Start free and upgrade as you grow. All plans include the full Pre-auth dashboard, secure payment links, and customer management.

A card action is any pre-authorisation, card-on-file save, capture, or charge. Releasing a hold does not count as a card action.
