Neighborhood group-purchase and payment signup system on bunq
This tool lets organizers run collective purchase rounds with items and prices on top of the bunq bank API: participants sign up via a shared link or embedded form and instantly receive a payment request in their banking app, the organizer sees who paid and who didn't, and can refund dropouts with one click. It is also used for neighborhood event logistics such as dinner signups and collecting dietary preferences.
What it addresses
Collective purchases organized through WhatsApp became risky and administratively heavy as membership grew to over 80 households per round, since the organizer had to front the money.
Shared over time
Each entry reflects what was shared on that date. Details may have changed since then.

“So I built a small system on top of the API of my bank, bunq. I set up a round with items and prices, share a link or embed the signup form in an existing site, and everyone who signs up immediately gets a payment request in their banking app. I can see who paid and who didn't, and refund someone with one click if they drop out.”
