Mae cyflwyno PBAs mewn contractau adeiladu yn ymrwymiad a geir yn y Strategaeth Gaffael ar gyfer Adeiladu a gafodd ei hardystio gen i ym mis Gorffennaf  2013. Hefyd, mae hyn yn cefnogi Polisi Caffael Cymru a gyhoeddais ym mis Rhagfyr 2012 sy’n nodi y dylai cyrff cyhoeddus fabwysiadu arferion da wrth dalu.
The introduction of PBAs in construction contracts is a commitment of the Construction Procurement Strategy that I published in July 2013. This also supports the Wales Procurement Policy that I published in December 2012 which requires public bodies to adopt best practice approaches to payment through the supply chain.
