B2B marketplaces: split checkout and per-supplier settlements
Mikołaj Lehman
CEO & Founder
B2B split checkout means one buyer cart can split into many fulfilments, payments and settlements, per supplier or warehouse.
Order data model
A parent order groups child orders with their own statuses and tracking numbers.
Buyers see one timeline with per-supplier filters.
Payments and trade credit
Payment operators and credit limits need idempotent endpoints and limit-change audit trails.
Some flows aggregate via the marketplace, some pay sellers directly, legal and UX must align.
Notifications and returns
Returning one line must not break other suppliers’ settlements, we design compensating flows and partial refunds.
Email and push must state which party owns the claim.
