When does a Milestone get synced to Xero as a Bill?
Milestones can be synced to Xero at different points in the Milestone lifecycle, depending on your Organisation's needs.
You can choose which points you want to sync at from the Xero settings under your Organisation settings by going to your Settings > Organisation menu and clicking on "Edit Details".
The following sync points are available for you to choose from; you can select multiple if you wish.
If you are not using Contracts within Tahua then the only option that is applicable is "When the Milestone is approved".
You can read more about Milestone payments [here](/knowledge-base/administrator-help-guides/payments/payment-integrations/milestone-payments-using-a-xero-integration.md).
What account code are bills coded to in Xero?
You are able to choose which account code your bills are coded to within your Tahua organisation settings.
Navigate to Settings > Organisation and click on "Edit details", locate the Xero Account Code field below:
N.B. You can override this code and apply unique Xero codes for individual funding rounds in the [Grant Round](/knowledge-base/administrator-help-guides/funding-rounds-and-grant-management/create-a-grant-round.md) setup process.

How often is payment information synced back to Tahua?
Payment information is pulled from Xero every 24 hours around midnight NZT.
How are Funding Categories tracked in Xero?
If you use Funding Categories, Tahua can track Milestone bills against them in Xero using Tracking Options under the Xero Tracking Category you select during setup (see [Getting Started with Xero](/knowledge-base/integrations-help-guides/xero/getting-started-with-xero.md)) — "We will create an option for each funding category under this tracking category."
Tracking Options aren't created up front. Instead, the first time a Milestone bill for a given Funding Category is synced to Xero, Tahua checks whether a matching Tracking Option already exists and creates one if it doesn't.
A couple of things to keep in mind:
* If you rename a Funding Category in Tahua, a **new** Tracking Option is created in Xero to match the new name next time a bill syncs — the old option isn't renamed or removed automatically, so you may end up with an unused option left behind in Xero that's worth tidying up.
* Organisations using Contracts can instead have bills tracked against the **Contract Category** rather than the Funding Category. This isn't a self-service setting — reach out to if you'd like this enabled. See [Contract Execution & Milestone Payments](/knowledge-base/administrator-help-guides/contracts/contract-execution-and-milestone-payments.md) for how Tracking Options fit into that flow.
