Extra-Zakcentje: a site about saving, comparing and earning extra

What was needed

Extra-Zakcentje helps visitors make smarter choices: where to save, which provider suits you, and how to earn something extra. The route is always the same: a search question, a decision aid and a click through to the provider.

That needed a site that can publish new topics at a steady pace, keeps comparisons up to date and can also sell digital products. All in Dutch.

What we built

• A site in Next.js with topic hubs, including one on money and children. Content and comparisons live in a PostgreSQL database, without a heavy CMS in between.
• Comparison tables with a reference date. Once the check date has expired, the price column disappears on its own, so no outdated prices are left on the page.
• A savings calculator without a mandatory email address, a side-income quiz and a free checklist through the newsletter in Systeme.io.
• A custom click-through link for product links to bol.com, so it is visible which links visitors use.
• A shop with digital packages: checkout through Stripe Checkout, downloads through temporary links from protected storage in Cloudflare R2, and email through Resend.
• A publishing process in which a draft only goes live after a person has reviewed and scheduled it.
• A custom cookie banner with Consent Mode, so Google Analytics only measures after consent.
