Why teams connect Easypost and Syspro

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

Easypost runs the storefront and takes the orders; Syspro 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 Parcel, Rate, Tracker, Batch in Easypost with Warehouses, Customers, Suppliers, Inventory items in Syspro field by field, in real time, and in both directions. You decide which system owns which fields — stock and pricing from Syspro, order and customer detail from Easypost — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Create a Tracker for every outbound shipment and stream tracker.updated webhook events into Postgres or a warehouse so support and ops see live delivery status beside order records.
  • 02 Verify and normalize customer Addresses through EasyPost before they are saved to the CRM or OMS to cut failed deliveries and carrier address-correction surcharges.
  • 03 Extract job and WIP data into a warehouse for production and costing reports
  • 04 Post shipment confirmations from logistics systems back against SYSPRO sales orders

Common sync patterns

One customer master

Where both systems keep customer records, a correction in either propagates to the other, ending dual maintenance.

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

Available quantities from Syspro 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 Syspro with customer, line items, and totals, so fulfillment and invoicing start without re-entry.

What you can sync between Easypost and Syspro

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 Syspro objects How this pairing syncs
Tracker Tracking for a shipment by tracking_code and carrier; create a Tracker to begin tracking, read status and tracking_details, and receive tracker.updated events via webhook as the parcel moves. Inventory items The stock master, kept aligned with WMS and e-commerce catalogs. Tracker is specific to Easypost and Inventory items to Syspro — each maps to any object or custom field on the other side.
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. Sales orders Orders written in from storefronts and CRMs, with status read back out. Batch is specific to Easypost and Sales orders to Syspro — 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. Purchase orders Procurement documents synced with supplier portals and receiving. CarrierAccount is specific to Easypost and Purchase orders to Syspro — 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. Jobs (work orders) Manufacturing jobs and WIP tracked for production reporting. Webhook is specific to Easypost and Jobs (work orders) to Syspro — 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. Bills of materials Product structures referenced when syncing manufacturing data. Shipment is specific to Easypost and Bills of materials to Syspro — 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. AR invoices Billing documents surfaced to CRMs and finance reporting. Address is specific to Easypost and AR invoices to Syspro — each maps to any object or custom field on the other side.

How changes propagate between Easypost and Syspro

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 Syspro 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 Syspro through its API, with automatic retries and rate-limit backoff.

Syspro Easypost Interval-based propagation

DetectionStacksync polls Syspro for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

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.
  • Syspro: Throughput depends on the customer's server sizing; many deployments are on-premise.
