When you need this

An approved supplier bill needs to post to Greentree as an AP invoice, attached to its Greentree purchase order.

Before you start

Greentree is connected and the Company code is set.
The bill is approved and has an invoice date.
The bill is linked to a PO that has already synced to Greentree. The AP invoice attaches to that Greentree PO, so the PO must sync first.
The supplier is linked to an active Greentree creditor.
The company's default tax type is mapped on Procurement → Tax code mapping.
The purchase type has a GL code (non-job bills), or an activity code (job-linked bills).
For job-linked bills: the job is synced to Greentree and its department is mapped to a profit centre.
Your role has the Greentree push permission under Finance, Reconciliation. Integrations access alone isn't enough.

Turn on Auto-push approved supplier bills to Greentree on the Procurement tab.
Approve the bill from Pending Bills or the dashboard. SprintSuite pushes it straight away and waits for Greentree's answer.

Result	What happens to the bill
Success	Approved, with a Greentree reference: Bill approved and synced to Greentree.
Greentree rejected it	Returned to draft: Greentree push failed, bill not approved. Fix the cause and approve again.
Unclear (no reference, no error)	Stays approved with a warning. Check Greentree before resending to avoid posting it twice.

If the approver doesn't have the Greentree push permission, the bill is approved without pushing. Someone with the permission can then use Option B.

One AP invoice per bill, with a single line.
Reference: BILL- followed by SprintSuite's internal bill ID.
Supplier: the linked creditor code.
Line: a job cost line (job plus activity code) when the PO's job is synced, otherwise a GL line.
Purchase reference: the synced Greentree PO.

Every bill in a batch is checked before anything is sent. If one fails the checks, none of the batch is posted.
Re-sending skips bills that already went through.
Supplier credit notes aren't pushed to Greentree.

The error shows on the bill under Greentree push failed.

Problem	Fix
Bill isn't approved, or was already pushed	Approve it, or check it already has a Greentree reference
PO not synced	Sync the PO first, then push the bill
Supplier unmapped or inactive	Link the supplier under Settings → Suppliers
Tax type unmapped	Complete Tax code mapping on Procurement
No GL code or activity code	Add the right code to the purchase type
Job not synced, or department not mapped	Sync the job, or map the department to a profit centre
Invoice date blank or amount zero	Fix the bill
Reference too long	The BILL- reference must be 20 characters or fewer. Contact SprintSuite support.
