Troubleshooting Integrations & 3PL Sync
Purpose
Fix the #1 integration complaint: “Account Editor shows change, but fulfillment system didn’t.”
⭐ Why This Matters
Most “edits didn’t apply” issues are not bugs—they’re sync timing and overwrite rules:
- 3PL imports order too early (before edit window ends)
- OMS locks orders or rejects edits
- Another app pushes the original order state back
⚙️ How It Works (Sync Reality)
A clean post-purchase edit flow requires:
- Customer order placed
- Edit window runs
- Order finalizes (paid/confirmed)
- 3PL imports final version only
If 3PL imports at step 1, you’ll see mismatch.
✅ Decision Tree
Step 1 — Did Shopify itself update?
Check Shopify order timeline:
- If Shopify did not update → treat as Order Editing troubleshooting (7.1)
- If Shopify updated → continue
Step 2 — Which integration is used?
- ShipStation / DPD / Brightpearl / CartRover / GetQuickMail / other
Step 3 — Identify failure type
A) Imported too early
Fix = delay import / hold order / delay dispatch
B) Overwrite rules
Fix = configure “allow edits” in OMS or avoid locked states
C) Partial sync
Fix = check which fields sync (address vs items) and configure accordingly
🧪 Real merchant scenarios
Scenario A — “3PL shipped old item, Shopify shows new item”
Cause: 3PL imported before edit window ended.
Fix: Implement delay/hold method (Cluster 5) for that provider.
Scenario B — “Address updated in Shopify but not in OMS”
Cause: OMS doesn’t accept address changes unless specific setting enabled.
Fix: Enable OMS “order edits”/equivalent and retest.
Scenario C — “Edits revert after a few minutes”
Cause: OMS sync job overwrote Shopify data.
Fix: Adjust sync direction rules; ensure OMS respects Shopify as source of truth after checkout edits.
❓ FAQs
Q: Is this an Account Editor bug?
If Shopify order timeline shows the update, Account Editor did its job. The remaining issue is integration timing or overwrite rules.
Q: What’s the best universal approach?
Delay/hold orders until the edit window ends, then release to 3PL.
⚠️ Common issues & fixes
Issue | Likely cause | Fix |
|---|---|---|
Shopify updated but 3PL didn’t | Imported too early | Delay import / hold order |
Address didn’t sync | OMS field sync disabled | Enable “order edits”/address update setting |
Changes revert | OMS overwrite | Adjust sync direction; add hold window |
Partial sync | Provider limitations | Use provider-specific setup guide |
