Sage 300 and Asana integration

What moves between them

Vendor master data and purchase order records flow from Sage 300 into Asana as tasks and project updates on a schedule you define. Vendor names, contact details, and payment terms from APVendors appear in Asana custom fields; purchase order status and line items from POPurchaseOrders map to task metadata. The sync is one-way from Sage 300 to Asana, since Asana is task-centric and has no financial endpoints to update. ml-connector polls Sage 300 on your cadence using OData date filters to retrieve only new or changed records, and writes into Asana via the REST API.

How ml-connector handles it

ml-connector stores your Sage 300 HTTP Basic Auth credentials (username and password, both uppercase) encrypted and includes them in every API request. It polls your Sage 300 instance on a schedule you control using OData $filter expressions like DocumentDate gt '2026-01-01' to retrieve only new records since the last sync. Each vendor and purchase order is mapped to an Asana task or project update, with financial metadata stored in custom fields you define. Asana custom fields are application-specific, so you specify which fields receive vendor data, which receive PO status, and which carry dates and amounts. ml-connector retries failed requests with exponential backoff and maintains a full audit trail of every record synced, including timestamps and any transformation applied. If a downstream write to Asana fails, the record is marked for replay so no data is lost.

A real-world example

A mid-sized manufacturing company uses Sage 300 for purchasing and AP and Asana for operations and project management. Purchase orders created in Sage 300 are currently invisible to the operations team in Asana until manually entered as tasks, creating duplicate work and delays. With the integration, purchase orders flow automatically into Asana as tasks tagged with vendor name, PO number, and expected delivery date via custom fields. Operations sees real-time PO status and invoice hold-ups without switching systems, and the purchasing team can view project timelines in context of outstanding commitments. Invoices from vendors are linked to their POs in Asana, so finance holds and payment delays are visible to everyone.

What you can do

• •Sync vendor master data from Sage 300 APVendors into Asana custom fields on a scheduled poll.
• •Push purchase order records from Sage 300 POPurchaseOrders into Asana as tasks with status, dates, and amounts in custom fields.
• •Authenticate Sage 300 using HTTP Basic Auth and Asana using OAuth2 or Personal Access Token.
• •Poll Sage 300 on a schedule tied to your AP cycle using OData filters to retrieve only new or changed records.
• •Maintain a complete audit trail of every record synced, with replay capability if a write to Asana fails.

Questions

Which direction does data move between Sage 300 and Asana?

Data flows one-way from Sage 300 to Asana. Vendor master records, purchase orders, and invoice data from Sage 300 are polled and written into Asana as tasks and project updates with custom fields. Asana is read-only in this relationship since it has no native finance objects to receive updates back.

How does ml-connector handle Sage 300's HTTP Basic Auth and on-premise infrastructure?

ml-connector stores your Sage 300 username and password encrypted and includes them as a base64-encoded Authorization header on every request. Since Sage 300 is on-premise and requires HTTPS, you configure the full instance URL including the host and IIS path. ml-connector connects directly to your IIS server and respects Sage 300's OData query options for filtering and pagination.

How are Sage 300 purchase orders and invoices represented in Asana?

Purchase orders and invoices from Sage 300 are converted to Asana tasks, with vendor names, PO numbers, dates, amounts, and status stored in custom fields you define. Since Asana has no invoice or PO objects, financial metadata is stored as text, number, or date custom fields on tasks so your team can filter, sort, and report on that data within Asana.
