Why teams connect Resend and Sage 100

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Resend and Sage 100.

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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Inventory Items, Sales Orders, AR Invoices, Purchase Orders in Sage 100 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

  • Sync CRM contact segments into Resend Audiences so lifecycle broadcasts target current data.
  • Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
  • Sync customers, invoices, and payment status into a CRM so sales sees AR standing without opening the ERP.
  • Push e-commerce and EDI orders into the Sales Order module instead of rekeying them.

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 Sage 100 carries account records

Order, invoice, or account status from Sage 100 appears alongside the customer in Resend, so front-line teams answer from live data.

Where Sage 100 is the HR or people system of record

Worker and organization data from Sage 100 stays current in Resend, so the tools people use daily reflect the org as it actually is.
