Golf Amsteldijk: booking a day pass in four steps

Golf Amsteldijk in Amstelveen has a 9-hole A-status course, a par 3 course, the 9 Werelden van Golf (9 Worlds of Golf) and a driving range. With a day pass, you can play there for a day without any experience. Your Tech Club built the app where golfers book and pay for that day pass, at dagkaart.amsteldijk.nl. The app runs on the WooCommerce store of amsteldijk.nl, the club website we also designed and built. The service kiosk in the clubhouse and the membership sign-up form followed later.

What did the app need to do?

A day pass is not an ordinary online store product. The golfer chooses a day to play and a number of passes. Anyone coming with friends wants everyone to get their own confirmation. Anyone without clubs wants to rent them at the same time. And because no experience is needed, the booking has to make sense without any golf knowledge.

Our choice: a booking flow on the existing store

Products, prices and discount codes were already in WooCommerce, and payments ran through Mollie. We did not replace that store. The booking app is a separate app on its own address that talks to the amsteldijk.nl store in the background.

Day passes and rental sets are products in two dedicated categories in WooCommerce. The app fetches them from there, with price and description, and creates the order there too. If the club changes a price or creates a discount code, it works in the app straight away. No second admin environment was added.

The WooCommerce and Mollie keys are not in the browser. The app talks to both systems through Supabase Edge Functions, so those credentials stay on the server side.

What we built

Booking takes four steps: choose a date and the number of day passes, fill in your details, rent clubs if you need them and pay with iDEAL. An order summary next to the form keeps track of the date, the number of passes and the total. On a phone, the summary sits below the form.

Four steps, from date to rental set

In the first step, you pick a date in the calendar and the number of day passes. The playing date goes into the order as a fixed day, so a time zone difference can never shift it by a day.

Next, you fill in your details: name, date of birth, postcode, email address and, optionally, your handicap and phone number. You accept the terms and decide whether you want the newsletter. This is also where you enter a discount code.

If someone books more than one day pass, they can also fill in their fellow players' details, so each of them gets their own confirmation email. This is optional.

In the third step, the app asks whether you already have golf equipment. If not, you choose a rental set, from a starter kit to a complete set with bag and trolley. You can rent up to six sets per order. A short list explains what equipment you need.

Payment and confirmation

The final step is paying with iDEAL via Mollie. At that point the app creates the order in WooCommerce, with Mollie's payment ID attached. That way the payment result ends up with the right order.

After a successful payment, the order is marked as paid in WooCommerce. The golfer sees a confirmation with the booking number, the date, the number of day passes and a map showing where the club is. The day pass itself, with a QR code, arrives by email.

If the payment fails, a separate page explains that the booking has been cancelled, with a button to start again. If the total after discount is zero euros, the app skips the payment step.

Discount codes and promotions

The club creates discount codes in WooCommerce. The app checks the code there and applies the discount, a percentage or a fixed amount, straight away in the order summary.

The app calculates temporary promotions itself. From December 2025 to the end of January 2026, and in July 2026, the second day pass was half price, based on the day the order was placed. The order summary then shows regular passes and discounted passes separately. That is also how they go into WooCommerce, so the amounts there add up.

In Dutch, English and German

Since April 2026, the app has also been available in English and German. Each language has its own address, so a link can open directly in the right language. If the link has no language in it, the app uses the language chosen earlier, or otherwise the browser's language. The names of the rental sets, the dates and the error messages are translated too.

Seamless with amsteldijk.nl

The 'Book a day pass' button in the amsteldijk.nl menu and the 'Book your day pass now' buttons on its pages lead to the app. The app uses the same fonts and colours as the club website, so the switch is not noticeable.

The cookie choice is shared too. Anyone who makes a choice on the club website or in the app is not asked again on the other Amsteldijk sites. Analytics and marketing cookies are off by default. Only after consent does the app measure how far visitors get at each step, without sending names or email addresses.

Next: a service kiosk and membership

The clubhouse has a touchscreen service kiosk. In 2026, we built the app that runs on it. The home screen offers three options: buy a day pass, take out a membership and book a tee time. You switch between Dutch and English at the top right.

The day pass and membership open on the kiosk itself. They are the same apps as online, in kiosk mode. The booking app also takes over the language chosen on the kiosk.

Tee times for the A-status course are booked through Nexxchange. That system cannot be embedded in another screen. So the kiosk shows a QR code and the golfer books on their own phone.

After a period without any touch, the kiosk returns to the home screen by itself. We deliberately switched off a separate time-out in the app, so the screen does not jump back halfway through a booking. Only necessary and functional cookies are on at the kiosk, so visitors there don't see a cookie banner.

Buying a day pass at the kiosk

In kiosk mode, the booking app is shorter. The date is fixed to today: anyone buying a day pass at the kiosk plays the same day. Surname, phone number and guest details are left out, and you answer the handicap question with two large yes and no buttons.

Payment does not happen on the kiosk itself. The screen shows a QR code. The golfer scans it with their phone camera and pays there with iDEAL. A message asks them to use the camera app, not the banking app. Meanwhile, the kiosk checks WooCommerce every three seconds to see whether the order has been paid. As soon as it has, the confirmation appears.

Every order gets a label in WooCommerce, website or kiosk. That shows the club which bookings come in through the kiosk.

Becoming a member via lidmaatschap.amsteldijk.nl

The sign-up form at lidmaatschap.amsteldijk.nl is ours too. It has three steps: your details, your address and the membership. You choose unlimited access to the 9 Werelden van Golf, the 9-hole A-status course or both, and a start date. Payment is monthly by direct debit.

The new member then signs the contract and the direct debit mandate digitally via Stiply. That works best on a phone, because of the verification through the bank. So on a phone, the form goes straight through to Stiply. On a computer and on the kiosk, it shows a QR code.

The request goes through a small dedicated server, so here too the integration key stays out of the browser. The form works in Dutch, English and German.

The result

The booking app, the kiosk and the sign-up form are all in use. Online and in the clubhouse, day passes are sold through the same app, and every booking arrives in the same store. Every order is complete, with playing date, passes, rental sets, guests, consents and where it was booked.

Since the launch in February 2025, we have extended the app step by step: discount codes, promotions, guest details, three languages and kiosk mode. Each extension builds on the same WooCommerce integration. The code for the kiosk and the membership form is checked automatically every week for vulnerable software packages.
