A custom application giving marketplace vendors direct control over customer communication and data.
Outcome
Dozens of vendors run their own customer communication from one marketplace, each seeing only their own data; scope enforced at the database on every request.
A multi-vendor marketplace in Belgium built its business on the Shopify platform. Their model depends on attracting and retaining independent sellers, but the platform's success created a natural gap between those sellers and their end customers.
This gap manifested as an operational problem. Vendors had no native tools to communicate with their buyers after a sale or to export their own customer data for marketing. This friction made it difficult for sellers to build relationships and grow their individual brands, creating a risk of vendor churn for the platform.
We were brought in to build a bridge. Our solution was a private Shopify application that provides vendors with an integrated suite of post-sale tools. It empowers them to manage customer relationships and analyze their sales data directly within the environment they already use.
The challenge
How we solved it
Technologies
Vendors can select one of their products and instantly generate a list of every customer who has purchased it. From there, they can compose and dispatch a bulk email to that specific group. This provides a direct line to their most relevant audience for product updates, feedback requests, or marketing.
This function allows vendors to export customer details for specific orders into a standard CSV file. The file includes names, emails, and shipping information, ready for use in external marketing tools or accounting software. It grants vendors true ownership and control over their sales data.
How we built it
Scoped every database request to the authenticated vendor, so isolation is not something a feature can forget. Dozens of small vendors share one application and one Shopify marketplace, and the failure that ends that product is one vendor seeing another's customers. The multi-tenant architecture applies the vendor scope at the data layer on every request, which means a new feature cannot accidentally widen it. Vendors authenticate through Shopify OAuth, Laravel queues sync their orders and products in the background without touching the live marketplace, and the React interface reduces segmentation and export to a few clicks, because the users are shop owners rather than analysts.
In the client's words
“One vendor seeing another's customers would have ended the product. It cannot happen. I checked.”
