The real cost of a broken 3PL connection

Your warehouse is moving. Your data is not.

Without integration
  • Manual CSV exports from your 3PL, twice a day

    Inventory is always stale. Oversells cost you revenue every peak period.

  • Orders emailed or uploaded to your warehouse by hand

    Delays in fulfillment. Orders disappear in inboxes during volume spikes.

  • Tracking numbers copy-pasted back into the store

    Customers get no shipping confirmation. Support tickets pile up.

  • Return receipts handled manually on both ends

    Refunds issued before inventory is verified. Shrinkage is invisible.

With Redefine 3PL integration
  • Inventory syncs live on every pick, pack, and receipt

    Your storefront reflects warehouse reality in seconds, not hours.

  • Orders push to your warehouse the moment they are placed

    No manual steps. Same-day fulfillment becomes real.

  • Tracking confirmation writes back to the order automatically

    Shipping email triggers the moment your 3PL scans the label.

  • Returns received at the 3PL restock inventory and start the refund

    Inventory restocks automatically. Refunds process on receipt.

What the integration covers

3PL ecommerce integration built for how warehouses actually work

Two-way inventory sync

On-hand counts update in your storefront every time your 3PL receives, ships, adjusts, or returns stock. No polling delays. No batch jobs.

Real-time order routing

Orders route to the right warehouse based on stock, shipping zone, or rules you set. Split-shipment logic across multiple locations is included.

Direct-to-API architecture you own

We build directly to your 3PL's API. No third-party middleware. Your integration does not break when a SaaS vendor changes pricing or kills a connector.

endpoint: POST /v2/orders/fulfill
auth: OAuth 2.0 / HMAC
retry: exponential backoff
fallback: queue + alert

Tracking passback automation

Carrier tracking numbers write back to the order the moment the label is scanned. Shopify or BigCommerce marks the order fulfilled and fires the shipping email automatically.

Multi-warehouse + multi-carrier

Route by region, SKU category, or carrier SLA. US East, US West, UK, EU. One integration layer, every location tracked.

Client

JWE Inc

Multi-channel distribution

Multi-channel distributor operating Shopify, Uniform Market, and a third-party logistics warehouse, all with separate, fragmented systems and no automated data flow between them.

The problem

Inventory, orders, and customer data sat in separate platforms with no connection. The team spent hours each day on manual reconciliation. Errors hit constantly. The 3PL warehouse had no direct link to the storefront or ERP.

What was built
  • Dynamics 365 Business Central implementation with Shopify two-way sync

  • 3PL warehouse integration for logistics and fulfillment operations

  • Uniform Market integration with automated inventory and order sync

  • Microsoft integration automation tools to remove manual workflow steps

Result
0%

of manual data entry eliminated across 3PL, Shopify, and ERP

Inventory, order processing, and data flow between platforms now run automatically. The 3PL warehouse receives orders in real time and pushes fulfillment status back with zero manual steps.

Integration type: 3PL + ERP + Ecommerce · Platform: Dynamics 365 BC + Shopify

Under the hood

Integration architecture built to not break

Every connection we build handles error recovery, retry logic, and data consistency from day one. Your warehouse does not stop because an API timed out once.

Event-driven triggers

  • Webhook on order create
  • Webhook on inventory adjust
  • Callback on label scan
  • Polling fallback (5 min)

Error recovery

  • Exponential backoff retry (5x)
  • Dead-letter queue for failed events
  • Slack / email alert on failure
  • Manual replay dashboard

Data consistency

  • Idempotency keys prevent duplicates
  • Reconciliation audit log
  • Nightly full-sync verification
  • Drift detection + auto-correct
Why Redefine over off-the-shelf connectors

An app-store 3PL connector solves the simple case. Your operation is not the simple case.

CapabilityTypical connectorRedefine custom build
Inventory sync frequencyEvery 15 min (polling)Real-time on every warehouse event
Multi-warehouse routingManual location mapping onlyRule-based auto-routing with split shipment
Error recoveryRetries once, then fails silentlyRetries five times, alerts your team, queues for replay
Custom return logicNot availableReceipt confirmation starts the refund and restocks
Maintenance dependencyBreaks when the SaaS tool changesYou own the code; no third-party dependency
ERP / WMS co-integration3PL only; ERP is separateSingle layer across 3PL, ERP, and storefront
Common questions

Questions you should ask before signing anything

Yes. We assess what your 3PL supports during discovery: REST API, EDI, SFTP file exchange, or webhook callbacks. Where no API exists, we build a secure file-based sync with the same reliability guarantees as a native integration.

App-store connectors work well until they do not: a 3PL API update, a Shopify version change, a pricing model shift, or a volume spike that exceeds the app's rate limits. A custom build gives you ownership of the code, visibility into every event, and the ability to add business logic the app never supported. If your current app is working, we will tell you to keep it.

A focused bidirectional sync covering inventory, order push, and tracking passback typically takes 3 to 5 weeks from kickoff to production. More complex scopes (multi-warehouse routing, ERP co-integration, returns logic) run 6 to 10 weeks. We scope it precisely before you commit to anything.

Scoped before work starts. Line-by-line pricing. No commitment to receive a proposal. A focused 3PL integration starts from $8,500 for a standard bidirectional sync. ERP co-integration and multi-warehouse logic are scoped separately. We send the number before you say yes.

Your team's time investment is typically 2 to 3 hours per week. One discovery call, one sprint review per week, and a final quality assurance sign-off. You introduce us to your 3PL contact. We handle API documentation review, development, testing, and go-live monitoring. You do not write a single line of code.
