We have a total gross contract amount of $8950. Retention on the project is 10%, We have invoiced as follows: WORK PERFORMED AND INVOICED FOR Progress billing #1: $980 - $98 retention = $882 net (Invoiced to GC, GC has not paid us) Progress billing #2: $7,340 - $734 retention = $6,606 net (Invoiced to GC, GC has not paid us) WORK NOT YET PERFORMED OR INVOICED FOR Progress billing #3: $630 - $63 retention = $6,606 net (Not yet invoiced to GC) RETENTION YET TO BE INVOICED Total retention to be billed on project is 10% of total contract amount, or $895. We have not invoiced for retention yet, as we have not completed our work on the project. I think it is possible that this facility may never re-open and we may never get a chance to do the remaining work (which would be invoiced under our progress billing #3). I believe I should lien project for following amount: $980 (for progress billing 1, includes retention amount of $98 not yet invoiced) $7,340 (for progress billing 2, includes retention amount of $734 not yet invoiced) My position is that by contract, we are due payment not only on progress billings 1 and 2, but also on the retention amount associated with these two progress billings, even though we have not actually invoiced retention yet. DO YOU AGREE?
