Sage 50 and Chargebee integration

What moves between them

The integration reads Sage 50 customers and invoices on a polling schedule and writes subscription customer records to Chargebee via REST. Chargebee invoices flow back into Sage 50's general ledger as sales transactions mapped to the appropriate GL accounts and customers. The main direction is bidirectional: customer and invoice data aligns between the two systems so that subscription customers in Chargebee match Sage 50 records, and invoices generated by Chargebee's billing engine post into Sage 50's accounts.

How ml-connector handles it

ml-connector runs a Windows process with Sage 50 SDK credentials and polls the Sage 50 data files on a configurable schedule, typically every 15 to 60 minutes. On the Chargebee side, it receives webhooks for customer and invoice events and stores them encrypted. When a customer is created or updated in Sage 50, ml-connector maps the customer to Chargebee's customer API and creates or updates the record. When Chargebee generates an invoice, the webhook triggers a sync to Sage 50 where the invoice is posted to the general ledger with the matching customer and GL account. Because Sage 50 does not have a cloud REST API, the Windows integration process must run on the same machine or network as the Sage 50 files, and the integration user must not have Sage 50 open interactively during the poll. Rate limits on Chargebee are tracked so that polling intervals back off when limits are approached. Every record carries a full audit trail so that a failed post can be replayed.

A real-world example

A small-to-medium software company uses Sage 50 for accounting and customer management, and Chargebee for monthly recurring billing across a growing subscription product. Before the integration, the finance team exported customer records from Sage 50 weekly and uploaded them to Chargebee by hand, then downloaded invoices from Chargebee and re-entered them into Sage 50 at month-end to reconcile the billing ledger. With Sage 50 and Chargebee connected, each customer change in Sage 50 flows to Chargebee automatically, invoices generated by Chargebee post directly into Sage 50's GL at the correct accounts, and the monthly re-entry work is eliminated.

What you can do

• •Sync customers from Sage 50 to Chargebee on a polling schedule, keeping subscription customer records aligned with your accounting master.
• •Post invoices generated by Chargebee back into Sage 50's general ledger mapped to the correct customer and GL account.
• •Receive Chargebee invoice and payment webhooks and log them to a full audit trail.
• •Bridge Sage 50 Windows SDK authentication with Chargebee's HTTP Basic Auth API.
• •Recover from failed posts by replaying records when Chargebee rate limits or Sage 50 is temporarily unavailable.

Questions

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

ml-connector runs a Windows process on the same machine or network as your Sage 50 installation. The process loads the Sage 50 SDK or COM API with the integration user's credentials and polls the data files at a configurable interval, typically every 15 to 60 minutes. The integration user must not be logged into Sage 50 interactively while the poll is running, because Sage 50 enforces exclusive access to the data files.

What records move between Sage 50 and Chargebee?

Customers created or updated in Sage 50 are synced to Chargebee as subscription customers. Invoices generated by Chargebee's billing engine are posted back into Sage 50's general ledger as sales transactions mapped to the appropriate GL accounts. Sales invoices already in Sage 50 are not modified by the integration.

How does ml-connector handle Chargebee rate limits?

Chargebee rate limits depend on the plan tier and range from 150 requests per minute for Starter to 3500 for Enterprise. ml-connector tracks the rate-limit headers returned by Chargebee and backs off the polling schedule when limits are approaching. If a request hits the limit, it is queued and retried after the limit window expires, so no data is lost.
