With this construction management Odoo app, you can manage project estimation costs, progress task-wise, and the balance remaining based on the budget spent on materials, manpower, and equipment which is recorded project tasks.

Before entering the material, personnel, or equipment records, the finance/admin manager must first approve the budget cost for each project work.

We have segregated the purchase order based on material and manpower and were able to map different PO for the respective projects.

For Material/manpower we need to create RFQ for suppliers based on supplier responses we will make RFQ as PO.
Once the material PO is confirmed delivery receipt will be created against the PO. After the delivery receipt is validated we can raise the vendor bill against PO.
