Why teams connect Easypost and NetSuite

Keep the storefront in step with the back office: Easypost and NetSuite share products, inventory, and orders in real time, in both directions.

Easypost runs the storefront and takes the orders; NetSuite owns the item master, the stock on hand, and the finance behind every transaction. The two overlap wherever the same products, customers, and sales matter to both — and when re-keying or an overnight batch is what connects them, the store oversells items it can't ship, quotes prices finance never set, or leaves buyers waiting on status that already changed.

Stacksync syncs Rate, Tracker, Batch, CarrierAccount in Easypost with Subsidiary, All custom objects, Nexus, Tax Type in NetSuite field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from NetSuite, order and customer detail from Easypost — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Sync CarrierAccount configuration and negotiated rates so shipping options stay consistent across the storefront, ERP, and 3PL systems.
  • 02 Pull Shipment, Rate, and Refund records into a warehouse to report shipping cost per carrier and service and reclaim postage on labels that were never scanned.
  • 03 Expose item and inventory data to internal applications through a continuously synced database table.
  • 04 Mirror journal entries and transaction lines into a warehouse for financial reporting without CSV exports.

Common sync patterns

Where NetSuite is the inventory system of record: stock stays accurate

Available quantities from NetSuite publish to Easypost, so the store shows what can actually ship and stops overselling.

New orders reach the back office

An order captured in Easypost creates the matching record in NetSuite with customer, line items, and totals, so fulfillment and invoicing start without re-entry.

One product catalog

Where both systems keep item records, SKUs, descriptions, and attributes stay aligned so the store and the back office describe the same product.

What you can sync between Easypost and NetSuite

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Easypost objects NetSuite objects How this pairing syncs
Batch Bulk shipment processing; create a batch, add or remove shipments, buy all labels at once, and generate a consolidated label or ScanForm for the day's orders. Tax Type Synced with incremental and full sync per the Stacksync docs. Batch is specific to Easypost and Tax Type to NetSuite — each maps to any object or custom field on the other side.
CarrierAccount Carrier credentials and settings that control which carriers and negotiated rates are available; create, update, and delete to manage enabled carriers across accounts. Sales Tax Item Synced with incremental and full sync per the Stacksync docs. CarrierAccount is specific to Easypost and Sales Tax Item to NetSuite — each maps to any object or custom field on the other side.
Webhook Event subscriptions delivering an Event via HTTP POST on object changes; full CRUD (create, retrieve, list, update, delete) and the mechanism for near-real-time change delivery to Stacksync. Billing Schedule Customer Subsidiary Relationship Synced with incremental and full sync per the Stacksync docs. Webhook is specific to Easypost and Billing Schedule Customer Subsidiary Relationship to NetSuite — each maps to any object or custom field on the other side.
Shipment The central writable object: create with a to/from Address and Parcel, receive Rate options, then buy a label to get postage_label and tracking_code; retrieve and list with cursor pagination. Account Synced with incremental and full sync per the Stacksync docs. Shipment is specific to Easypost and Account to NetSuite — each maps to any object or custom field on the other side.
Address Origin and destination locations; create, retrieve, and list, plus address verification (delivery and residential) to normalize and validate addresses before they are saved downstream. Accounting Period Synced with incremental and full sync per the Stacksync docs. Address is specific to Easypost and Accounting Period to NetSuite — each maps to any object or custom field on the other side.
Parcel Package dimensions and weight (or a predefined_package); created standalone or inline on a Shipment and reused across shipments and batches. Bin Transfer Synced with incremental and full sync per the Stacksync docs. Parcel is specific to Easypost and Bin Transfer to NetSuite — each maps to any object or custom field on the other side.

How changes propagate between Easypost and NetSuite

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Easypost NetSuite Sub-second propagation

DetectionEasypost notifies Stacksync of record changes through webhook events. Webhooks deliver an Event via HTTP POST on object changes (e.g.

DeliveryEach detected change is written to NetSuite through its API, with automatic retries and rate-limit backoff.

NetSuite Easypost Interval-based propagation

DetectionStacksync polls NetSuite for changes on an incremental schedule, reading only records changed since the previous pass. Polling on lastModifiedDate via SuiteQL or saved searches.

DeliveryEach detected change is written to Easypost through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Easypost: Fixed 5 requests/second on index (list) endpoints plus a dynamic load-based limiter protecting buy and rate operations; exceeding either returns HTTP 429 Too Many Requests.
  • NetSuite: API concurrency is governed per account; sync tools queue and throttle requests.
