Sage 50 and HubSpot integration

What moves between them

Customer and vendor records flow from Sage 50 into HubSpot as contacts and companies. Sales invoices from Sage 50 flow into HubSpot invoices and line items, associated to the matching contact and company. Purchase order statuses and payment changes in Sage 50 can sync back to HubSpot deals if deals are created to track those orders. The sync runs on a polling schedule set to the company's transaction frequency: typically every 15 to 30 minutes during business hours, and can be run hourly or on-demand. Sage 50 has no webhooks, so all records are discovered by polling LastModifiedDate on customer, vendor, and invoice entities.

How ml-connector handles it

ml-connector runs in a Windows container or on a Windows server with Sage 50 installed, and stores the Sage 50 ApplicationID, CompanyPath, username, and password encrypted for the integration user. On each poll cycle, it connects to Sage 50 via the local SDK, queries customers, vendors, and invoices modified since the last sync, and maps each to the appropriate HubSpot entity: customers to companies, vendors to a separate vendor company list, and invoices to HubSpot commerce objects. It stores the HubSpot bearer token encrypted and refreshes it before expiry. Because Sage 50 requires exclusive local access (the integration user cannot be logged in interactively while the SDK session is open), ml-connector batches queries and commits to minimize lock contention. Invoices are associated to contacts and companies by matching on customer or vendor ID from Sage 50. Each record carries the original Sage 50 ID in a custom field so updates in HubSpot can be traced back to the source. The integration polls on a schedule; it does not wait for a Sage 50 event because Sage 50 has no event system.

A real-world example

A mid-market B2B distribution company runs Sage 50 US for accounting and order processing, and HubSpot for sales pipeline and customer management. Before the integration, the sales team manually entered new customers into both systems, and the finance team exported invoices from Sage 50 and uploaded them to HubSpot as PDF attachments because there was no direct link. Deal stage advances in HubSpot were not reflected in Sage 50 order status. With Sage 50 and HubSpot connected, each new customer created in Sage 50 flows into HubSpot as a company and contact within minutes, invoices post automatically and are visible in the HubSpot deal record without manual upload, and order status updates flow both directions so sales and accounting see the same current state.

What you can do

• •Sync customers and vendors from Sage 50 into HubSpot as companies and contacts with a unique identifier to track updates.
• •Flow sales invoices from Sage 50 into HubSpot invoices and line items, associated to the matching customer contact.
• •Map purchase orders from Sage 50 to HubSpot deals when a deal has been created for that order.
• •Poll Sage 50 on a schedule and handle the exclusive local access requirement so the Windows SDK connection does not lock interactively.
• •Store Sage 50 credentials encrypted and refresh HubSpot bearer tokens automatically.

Questions

How does ml-connector connect to Sage 50 if there is no cloud API?

ml-connector runs on a Windows machine with Sage 50 installed and uses the local .NET SDK or COM ActiveX DLLs to query customer, vendor, and invoice records directly from the Sage 50 data files. The integration stores the Sage 50 username, password, ApplicationID (US edition), and CompanyPath encrypted, and connects via the SDK on each poll cycle. This requires that the integration user is not logged in interactively to Sage 50 at the same time.

What records move between Sage 50 and HubSpot, and in which direction?

The primary flow is from Sage 50 into HubSpot. Customers and vendors from Sage 50 become companies and contacts in HubSpot, and sales invoices flow into HubSpot invoices and line items. Purchase order statuses and payment changes can flow back to HubSpot deals if deals exist for those orders. Because HubSpot invoices are in beta and Sage 50 has no webhooks, the integration pulls data on a polling schedule and may not capture every intermediate state change.

How often does the sync run, and what happens if Sage 50 is locked?

The sync runs on a configurable polling schedule, typically every 15 to 30 minutes during business hours. If the Sage 50 user is logged in interactively when ml-connector tries to connect, the SDK connection will block or fail because Sage 50 requires exclusive access to the data files. ml-connector retries on exponential backoff and logs the failure so the integration team can intervene if Sage 50 is unexpectedly in use.
