Creating vendor Change Orders and Prime Change Orders

A vendor CO changes a Commitment, while a PCO changes the Prime Contract.

A vendor CO changes a Commitment, while a PCO changes the Prime Contract.

Best for: Project managers coordinating cost and revenue · Requires: Access to the affected contracts and changes.

Within a Change Event:

  1. Add a vendor Change Order for each affected Commitment.
  2. Add line items with cost code, cost type, amount, retention, and subproject as applicable.
  3. Add a PCO when the Prime Contract should change.
  4. Review the PCO amount and its budget impact.
  5. Complete the appropriate approval or e-signature lifecycle.

One Change Event can include multiple vendor COs and a PCO. Their amounts do not have to be identical; margin, allowance, and non-billable cost decisions can make cost differ from owner billing.

For Sage-connected projects included in accounting integrations, you cannot create a PCO while the Budget has no line items. For many customers, those lines come from the Sage estimate, but Constructable requires budget lines rather than a specific estimate link.

If that happens, see A Prime Change Order cannot be created.

When vendor pricing is the starting point, continue with Copying vendor change costs to the Prime Contract.
