From sign-up to stall.
Your entire market in one place.
Mapp handles vendor registrations, the map, the planning for each market day and the invoices. Less email and Excel, more time for the market itself.
Personal onboarding · Suitable for multiple seasons and market days
Everything for your market
No more scattered lists. One system that keeps up.
From the first registration to the last invoice: every step lives in Mapp, per season and per market day.
Registrations
Vendors register through an online form that you build yourself. You approve, decline or waitlist per market day.
Map
Draw your market on the map and place stalls at true scale. Show the map on your own website if you like.
Seasons & market days
Manage multiple markets and seasons side by side, each with its own dates, stalls and rates.
Invoicing
Create invoices for all approved vendors in one go, email them and let vendors pay with iDEAL. A cancellation automatically produces a credit note.
Vendor portal
Vendors log in themselves, view their spot and invoices, and submit change requests for you to review.
Staff & parking
Plan staff, volunteers and tasks, and arrange parking spaces and traffic routes for market day.
Email & templates
Send mailings to all or selected vendors with your own templates and merge fields, and see what was sent.
Multilingual
Let vendors register in their own language. The form and emails are sent in that language automatically.
Map & planning
Draw your market and plan every spot.
Place stalls at true scale on the map, measure distances and assign vendors to their spot for each market day.
- Stalls and separators to scale, for example 4 × 4 metres
- Measure distances right on the map
- Public map for your website: visitors see who is where on each market day

- Draft, sent or paid: always see what is outstanding
- A payment link for iDEAL in the email, through your own Mollie account
- Credit notes for cancellations are prepared automatically
