Sage 50 and Dayforce integration

What moves between them

The main flow runs from Dayforce into Sage 50. After each payroll period, ml-connector reads employee records and payroll cost allocation data from Dayforce and syncs them into Sage 50 employee records and GL journal entries. The sync runs on a daily schedule tied to your payroll calendar. Employee hires, terminations, and transfers in Dayforce are reflected in Sage 50 employee records. Payroll cost allocations from Dayforce are mapped to Sage 50 GL accounts and posted as journal lines, allowing cost centers and departments to be allocated across your chart of accounts.

How ml-connector handles it

ml-connector stores the Dayforce client ID, username, and password encrypted and refreshes the OAuth 2.0 bearer token every 55 minutes before expiry to avoid service interruption. It retrieves the client-specific base URL via the ClientMetadata endpoint and caches it for 24 hours. On the Sage 50 side, ml-connector uses the local SDK connection (Windows process with direct access to the company data files) to write employee and GL journal records. The integration polls Dayforce daily using filterUpdateDateRangeMin and filterUpdateDateRangeMax to fetch changed employee and payroll records since the last sync. Sage 50 GL account write support is limited and does not permit changes to the fundamental account structure, so the integration maps payroll cost lines to existing GL accounts. The integration tracks every record in an audit log and can replay failed syncs if a downstream Sage 50 write fails. Because Sage 50 requires exclusive access to the local data files, ml-connector cannot run while Sage 50 is open interactively on the same machine.

A real-world example

A mid-sized accounting and consulting firm runs Sage 50 on a Windows desktop for finance and client accounting, and uses Dayforce for payroll and HR across three offices. Before the integration, the finance team manually entered employee data from Dayforce into Sage 50 and re-keyed payroll cost allocations into the general ledger each month, then spent days in month-end close reconciling GL labor accounts against actual payroll. With Sage 50 and Dayforce connected, employee records and payroll costs sync automatically on a daily schedule, reducing manual entry and reconciliation errors. Month-end close now starts with labor accounts already aligned to actual payroll, and the finance team reclaims time for higher-value analysis.

What you can do

• •Sync employee records from Dayforce into Sage 50, including hires, terminations, and transfers.
• •Post payroll cost allocations from Dayforce into Sage 50 GL journals, mapped to your chart of accounts.
• •Refresh Dayforce OAuth 2.0 tokens automatically every hour to prevent authentication failures.
• •Retrieve and cache the client-specific Dayforce base URL daily to minimize redirect overhead.
• •Poll Dayforce on a daily schedule for changed employee and payroll records, with a full audit trail on every sync.

Questions

Which direction does data move between Sage 50 and Dayforce?

The main flow is from Dayforce into Sage 50. Employee records, hires, terminations, and payroll cost allocations are synced from Dayforce into Sage 50, where they populate employee records and GL journals. Sage 50 GL accounts are read-only in this integration, so ml-connector does not write back to Dayforce payroll or HR records.

How does the integration handle Dayforce token expiry and the client-specific base URL?

ml-connector refreshes the Dayforce OAuth 2.0 bearer token every 55 minutes, well before the one-hour expiry, to prevent authentication failures during syncs. The client-specific base URL is retrieved from the ClientMetadata endpoint and cached for 24 hours to reduce redirect overhead and API load.

What happens if Sage 50 is open interactively while the integration runs?

Sage 50 requires exclusive access to local company data files, so the integration cannot write employee or GL records while Sage 50 is open on the same machine. Schedule integrations during off-hours or when Sage 50 is not in use, and monitor the audit log to confirm when syncs have completed.
