Back in November I did some freelance work for 2x companies (Company1, and Company2, who are subconsultants on Co1's job). I invoiced both companies separately, but at the same time, on Dec 1st. Company1 have paid up. Company2 have not yet paid. We are now 10 weeks down the line.
Co2 say that as Co1 was the main consultant, and Co2 were only a sub-consultant, they are not liable for my invoice - and Co1 sould take care of it. Co1 say that as the work was done for Co2 and the work benefitted them, then Co2 should pay up. I don't mind who pays, I just want paying and am now frustrated at the lack of payment. I understand the argument, though.
I have contacted Co2 to chase them up, as the invoice went directly to them. They told me about the conflict between themselves and Co1. I contacted Co1, my main client on the project, and my [apparently very busy] contact said he will sort it out back in early January. Despite my numerous phonecalls and emails he has not sorted it out.
On my original invoice back in December I stated that overdue payments would incur a 1.5% per month interest. As yet that has not been enforced. I am willing to do that. It will possibly endanger my chances of getting more work with either client, as they may perceive me as being impatient. I don't particularly want to endanger my chances.
Does anyone have experience of this? Or any advice on what the next step might be?
Or just sit tight and wait?
Or keep phoning/emailing every other day?
Or express my frustration to my client?
Thanks for any considered responses.
