When you need this

You want approved purchase orders to create or update a matching purchase order in Greentree automatically.

Purchase type mapping is how lines are coded. It isn't the PO sync itself. See Code a purchase request or PO for Greentree for line coding.

Before you start

Greentree is connected and the Company code is set.
SprintSuite support has switched on Greentree PO sync for your company.
Branches are synced, and either a default branch is set or your company has only one active branch.
Tax Codes are synced.
The supplier is linked to a Greentree creditor (Settings → Suppliers).
Every purchase type you use has a GL code for non-job lines, and an activity code for job lines.
Any job on the PO is synced or linked to Greentree.

Create the purchase request or PO as usual. Pick a Greentree tax code on every active line.
Approve it. Approval queues the sync, and the PO's Greentree status shows Syncing… then Success.

Header: PO reference, the linked supplier, the branch, delivery date, and description.
Job lines: the job's Greentree code plus the purchase type's activity code.
Non-job lines: the purchase type's GL account.
Tax: each line's Greentree tax code, inclusive or exclusive.

Approved POs arrive in Greentree with status Entered. That's Greentree's approved, actionable state, not a draft.

If none of these resolves to an active branch, approval is blocked.

Re-Synchronise pushes changes to a PO that's already synced.
Retry Sync re-queues a failed PO. Retry Failed Syncs on the PO list does this in bulk.
A sync still Syncing after 90 seconds is marked Failed so you can try again.
Rejecting a PO that's already in Greentree cancels it there.

The PO shows Success and stores its Greentree PO reference.
Greentree shows the PO with status Entered and the expected supplier, branch and lines.
Supplier bills against this PO can now be pushed. Bills need the PO synced first.

The error appears on the PO and in its activity feed.
