Contracts (Subcontracts & Purchase Orders)
Create commitments — subcontracts and purchase orders — against the budget, manage their lines and change orders, and track committed cost.

Contracts are your commitments — the money you owe to subcontractors and suppliers. Syntecton supports two commitment types: subcontracts (for trade contractors) and purchase orders (for materials and services). Both reduce available budget as committed cost.
Create a commitment
1
Choose the type
Go to Financial Control → Contracts and create a Subcontract or Purchase Order.
2
Select the vendor
Pick the contractor or supplier from the project resources/directory and enter the commitment number.
3
Add lines
Add line items, each mapped to a cost code with an amount. The total becomes the commitment’s original value.
4
Execute and manage changes
Execute the commitment when signed. Scope changes are handled with Subcontract Change Orders or PO Change Orders, which adjust the revised commitment value.
Troubleshooting
Committed cost looks too high
Check for duplicate commitments against the same scope, and confirm change orders were posted rather than left in draft.
