SYSPRO and Stampli integration

What moves between them

The primary flow is invoices and payments from Stampli into SYSPRO. Approved invoices exported from Stampli are parsed by ml-connector and posted into SYSPRO's GL through e.net Business Objects, mapped to the matching SYSPRO GL accounts and cost centers. Vendor master records are synced in both directions so SYSPRO vendor codes match Stampli vendor identifiers and approval workflows reference valid vendors in both systems. GL account and cost center reference data is kept aligned so invoice line allocations land on valid SYSPRO dimensions. Because Stampli exports are read-only, invoices already posted in SYSPRO are not written back; ml-connector tracks the export file names and content hashes to avoid duplicate posts on repeated file fetches.

How ml-connector handles it

ml-connector stores SFTP credentials encrypted and connects to Stampli's designated outbound directory on a configurable schedule, typically every 15 minutes. On each poll, it reads exported invoice and payment CSV or XML files, deduplicates by file hash and invoice number against prior imports, and batches the approved invoices for posting into SYSPRO. For each invoice, the connector maps Stampli GL accounts and cost centers to their SYSPRO equivalents, constructs the XML payload for e.net Business Objects, and submits the GL posting with the customer's session token or Basic Auth credentials. Because SYSPRO's e.net requires a valid session token that expires on logoff, ml-connector refreshes the token before each batch if needed. Reference data such as GL accounts and vendors is synced first in both directions to ensure all mapping targets exist before posting. Vendor changes in Stampli are exported on a 5 minute cycle and pulled into SYSPRO to keep the vendor master aligned. Posting errors are captured, logged with the invoice number and SYSPRO response, and surfaced in the audit trail for manual review; successfully posted invoices are marked so a repeated file export does not duplicate the GL entry.

A real-world example

A mid-sized electronics components distributor uses SYSPRO for their ERP and Stampli to manage vendor invoices and approvals across three offices. Before the integration, the AP team approved invoices in Stampli, then downloaded CSV reports and manually entered each approved invoice into SYSPRO's GL, reconciling vendor names and cost center codes by hand. This took 8-10 hours per week and introduced data entry errors that appeared days later in the GL reconciliation. With SYSPRO and Stampli connected, each approved invoice flows automatically into SYSPRO on a 15 minute cycle, vendor changes stay in sync, and the GL reflects current AP activity without manual re-keying. The AP team now focuses on exception handling and vendor negotiations instead of data entry.

What you can do

• •Sync approved invoices from Stampli into SYSPRO general ledger, posted to the matching GL accounts and cost centers.
• •Keep SYSPRO vendor master aligned with Stampli vendor changes so approvals reference valid vendors.
• •Map Stampli GL accounts and cost centers to SYSPRO dimensions before posting.
• •Deduplicate invoices across repeated SFTP file exports to prevent duplicate GL entries.
• •Poll Stampli on a 15 minute schedule and post invoices to SYSPRO with full audit trail and error capture.

Questions

Which direction does data flow between SYSPRO and Stampli?

The primary flow is invoices and payments from Stampli into SYSPRO. Approved invoices are parsed from Stampli's SFTP exports and posted into SYSPRO's GL. Vendor master and GL account reference data are synced in both directions to keep both systems aligned. SYSPRO GL postings are read-only in Stampli, so ml-connector does not write financial entries back from SYSPRO.

How does ml-connector handle the lack of a public Stampli REST API?

Stampli publishes no public REST API for third-party integrations. ml-connector uses SFTP file-based integration instead, connecting to Stampli's designated outbound directory to download exported invoices in CSV or XML format on a 15 minute poll cycle. File parsing, vendor mapping, and GL account allocation are handled in-memory, and successfully posted invoices are tracked to prevent duplicate GL entries on repeated exports.

What happens if SYSPRO's session token expires or an invoice posting fails?

ml-connector refreshes SYSPRO's session token before each batch of GL postings, so expired tokens do not block the integration. If a GL posting fails, the error is captured with the invoice number and SYSPRO response code, logged in the audit trail, and surfaced for manual review. The invoice is not marked as posted, so it will be retried on the next poll cycle once the underlying issue is resolved.
