Why teams connect Acumatica and Resend

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Resend and Acumatica.

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Resend is closer to the work, and the two often need the same facts about the same people, organizations, and transactions. Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.

Stacksync syncs API keys, Emails, Contacts, Audiences in Resend with Stock Items, Shipments, Payments, Journal Transactions in Acumatica bi-directionally and in real time, with field-level mapping and rules for which system wins on conflict. Changes made where the work happens reach the system of record within seconds, and the reverse.

Common use cases

  • Feed open and click events into a warehouse for engagement analytics alongside product data.
  • Sync CRM contact segments into Resend Audiences so lifecycle broadcasts target current data.
  • Sync vendor bills from AP automation tools into Acumatica for approval and payment.
  • Align Acumatica's built-in CRM opportunities and cases with an external sales or support platform.

Master data corrections travel

A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.

Where Resend faces customers and Acumatica carries account records

Order, invoice, or account status from Acumatica appears alongside the customer in Resend, so front-line teams answer from live data.

Where Acumatica is the HR or people system of record

Worker and organization data from Acumatica stays current in Resend, so the tools people use daily reflect the org as it actually is.
