Adding a 3PL to your fulfillment network should be a contract negotiation, not a six-week integration project. Here's where it usually falls apart. 01 - Per-3PL APIs ### Every 3PL has its own API, its own EDI, its own quirks Major 3PLs offer modern REST APIs (ShipBob, ShipHero); regional ones run on EDI X12 over SFTP; small ones email CSVs. Wiring all three patterns into your OMS takes a different project per partner. COVERAGE 02 - Inventory drift ### Your storefront thinks you have 100 units; the 3PL has 78 Inventory adjustments at the 3PL (damages, recounts, returns) lag back to your OMS. Customers buy what isn't there; refunds and apologies follow. FULFILLMENT 03 - Routing logic ### Picking the cheapest fulfillment route is manual With 5 3PLs, optimal routing changes per order based on inventory, distance, carrier rates, and SLAs. Most teams hard-code rules and lose 5–10% on suboptimal fulfillment. OPTIMIZATION PLATFORM ## Six products. One Platform. Replace many legacy vendors.

[Talk to a solutions architect](https://www.stacksync.com/book-a-demo) ### Can we route orders dynamically across 3PLs? Yes. Stacksync exposes a routing engine, define rules (cheapest, fastest, by zone, by inventory) and it picks the optimal 3PL per order, then sends it via that 3PL's preferred protocol. ### What about EDI 940/943/944/945 transactions? Full support. Stacksync's EDI engine handles standard 4PL/3PL transactions (940 warehouse shipping order, 943 warehouse stock transfer shipment advice, 944 receipt advice, 945 shipping advice) as first-class operations, not raw bytes. ### How real-time is inventory sync? Sub-second for 3PLs with webhook support (ShipBob, ShipHero, ShipStation), 1–5 minutes for poll-based 3PLs, 30 minutes for EDI-only ones (transmission cadence is configurable per partner). ### Can small / regional 3PLs that only do email + CSV work? Yes. Stacksync ingests from SFTP, email attachments (S/MIME), and shared drives, parses common CSV / fixed-width formats, and syncs them into your OMS like any other connector. ## Your last integration took months. Your next one takes a prompt. [Book a demo](https://www.stacksync.com/book-a-demo) [Get started](https://app.stacksync.com/)
