Cost depends on how many of J&T's 13+ markets you're shipping to—each country has its own API endpoint and COD reconciliation rules, especially tricky across Indonesia, Thailand, and the Philippines. Their API handles order creation and tracking well, but you'll need custom work for returns management and failed delivery workflows since J&T doesn't provide those endpoints.

If you're pushing high volumes through NetSuite's rate limits while managing multi-currency transactions and country-specific customs docs, expect more development time. Synkka's pre-built connector can get you running in 5 days for standard shipping, but complex scenarios like cross-border landed costs or real-time webhook tracking still need custom builds.

When J&T marks a parcel as undeliverable or returned, the integration updates the fulfillment record in NetSuite and can trigger a return authorization, inventory adjustment, or re-delivery workflow. The specifics depend on your business rules. Some clients re-attempt delivery automatically. Others route returns through a review queue. We configure the logic during implementation.

Typically 6 to 8 weeks from kickoff to go-live. The first couple weeks cover scoping: mapping your fulfillment workflow, identifying which J&T countries are in play, and defining COD reconciliation rules. Build and testing takes another four to six weeks, including a parallel run where automated records are checked against your existing manual process.

The standard milestones: picked up, in transit, out for delivery, delivered, and failed delivery. Each status update writes to the fulfillment record in NetSuite with a timestamp. For failed deliveries, you can configure automatic workflows like creating a return authorization or scheduling a re-delivery attempt.

J&T's API and data formats differ by country. Indonesia, Vietnam, the Philippines, Thailand, and Malaysia each have their own quirks around tracking IDs, settlement schedules, and invoicing. We handle the normalization so NetSuite gets consistent records regardless of which market the shipment originates from. During scoping, we'll identify which countries you ship through and configure each one.

J&T collects cash from your customers and remits it in batches, typically every few days depending on the country. The integration breaks each batch down by order, matches the collected amount to the corresponding NetSuite invoice, and posts J&T's carrier fees as a separate expense. Discrepancies between expected and remitted amounts are flagged automatically so your finance team catches them in hours, not weeks.
