I'm an owner on a project. We have a contract with 5% retainage with our GC. The GC in turn has 10% retainage with their subs. The sub submits to the GC for $100 for completed and stored work, and $90 for the current payment due. GC pays the $90, then sub has to invoice for $10 at end of the project Should the GC submit to us (as the owner) completed and stored work of $100 or $90? We then subtract our retainage from that amount for the current payment due.
