Schools are not currently included in this policy; however, it is best practice to ensure you have a PO number before you commit to any work with schools.
Nid yw ysgolion wedi'u cynnwys yn y polisi hwn ar hyn o bryd; fodd bynnag, arfer gorau yw sicrhau bod gennych rif archeb brynu cyn i chi weithio gydag ysgolion.
