Why teams connect Easypost and Twenty CRM
Keep the customers and orders that Twenty CRM and Easypost share aligned in real time, so sales works from live purchase history and the store works from current account details.
Twenty CRM holds the customer relationship: the contacts, accounts, and deals a go-to-market team works. Easypost runs the buying side: who placed which order, what they bought, and where it ships. The two describe the same people and companies, and when they are connected only by exports, sales answers questions without recent orders in front of them while the store works from account details that changed weeks ago.
Stacksync links Notes, Custom Objects, Attachments, Workspace Members in Twenty CRM to Shipment, Address, Parcel, Rate in Easypost with bi-directional, real-time sync. New customers, order activity, and corrected contact details move in whichever direction you configure, field by field, with conflicts resolved by rules you set. A record created or changed on either side shows up on the other within seconds, with no CSV exports and no nightly job.
The shared entity is the customer, matched on email or an external ID, so both systems agree on who the buyer is and the order history sits next to the relationship instead of in a separate tab.
Common use cases
- 01 Push product usage or billing data from a warehouse into Twenty custom fields to give reps account context.
- 02 Sync Opportunities into a finance system to keep revenue forecasts current.
- 03 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.
- 04 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.
Common sync patterns
One customer identity across sales and store
A person who exists as a contact in Twenty CRM and a buyer in Easypost is kept as a single, deduplicated record, so both teams work from the same customer instead of two partial copies.
Where Easypost records orders: purchase history on the account
Orders and their status from Easypost appear on the matching contact or account in Twenty CRM, so reps see what a customer has bought and what is in flight before the next conversation.
New buyers become CRM records
A customer created in Easypost creates or updates the matching contact or account in Twenty CRM, so first-time and repeat buyers land in the relationship system without a manual import.
