Scaling international seller operations
Mountalis refined how independent sellers published products and completed transactions in international markets.
Client
A digital commerce ecosystem connecting professional sellers with buyers seeking unique design pieces and luxury goods. The selection comes from dealers, galleries and independent makers rather than traditional retail channels.
Challenge
Independent sellers and international buyers brought different data and transaction requirements into the same marketplace.
Inconsistent catalog data
Thousands of sellers described rare and collectible pieces in different ways, making product information difficult to standardize within the marketplace.
Seller inventory accuracy
Many sellers managed inventory through galleries and external systems, leading to outdated availability and canceled purchases.
High value purchase negotiation
Expensive collectible pieces often required questions, offers and direct seller coordination before a transaction could move forward.
Cross border transactions
International purchases introduced duties, restrictions, documentation and payment requirements that varied by product and destination.
Solution
- 01
Guided seller listing tools
We redesigned the listing process with category specific fields, contextual guidance and validation that helped sellers provide complete and consistent product information.
- 02
Inventory synchronization services
We developed synchronization services that kept inventory aligned between external seller systems and marketplace listings in near real time.
- 03
Offer management system
We built an offer management system that organized negotiations, buyer questions and seller responses.
- 04
Transaction requirements manager
We created a transaction manager that applied country specific requirements to each product and destination.
Result
The marketplace established one purchase journey for rare inventory regardless of seller or destination.
