Option 1: Direct supplier APIs
Pros: full control, no markup, no third-party dependency. Cons: 4 separate integrations (AliExpress DS Open Platform, CJ Merchant API, Spocket Open API, Printful API), 4 webhook handlers, 4 retry policies, 4 auth schemes. Realistic to maintain at 3+ engineers. Not realistic for a 1-2 person team.
Option 2: DSers / Spocket as middleware
Pros: one dashboard, one workflow. Cons: USD-first pricing (you reconcile FX manually), no BD courier integration (you hand-off Pathao/RedX yourself), no bKash/Nagad webhooks. Workable for US/EU dropshipping; partial for BD.
Option 3: DropShop BD unified API
One API key, four suppliers, three BD couriers, three BD payment methods. BDT-native pricing. The opinionated middle path — give up some configurability for a workflow built around the BD operating model.
