Whenever you have to purchase any material item you have to prepare a purchase order and send it to your vendor.

To create a PO click on the “Create PO” option that you can find on the left side of the Construction Project Management Dashboard as shown in the image above.

Then select the material item by clicking on the dropdown arrow. The code of that item will automatically appear. Enter the quantity and the unit price of the item. Then select the Tax rate and press “Add”.
You can add multiple material items in a single PO.
Select the vendor from whom you want to buy these items. You can easily add a vendor to your vendor list by clicking on the “Click here to add new vendors” link.
Also select the delivery date of the items. You can add a note which you want to send to the vendor.
After filling all the information, click on the “Generate PO”.

You’ll then receive a pdf of PO generated which you can either cancel or revise whenever you want.
