I work sometimes in an arts-related field as an independent contractor for a certain 501(c)3. Over the last twenty years, I have helped them with an annual project, for which I have been paid and hourly rate. If it matters, the amount is usually between $600 and $1000 per year.
This year, I submitted my invoice using the method I did every other year. While I'm usually paid within a week or two, I have not been paid yet. It's been 1 month. I've written to confirm receipt of my invoice and asked to be informed when the check will arrive but received no response. It's a reputable organization, run by people whom I have met (i.e. not a scam).
Other contractors are having a similar experience. I'm concerned that the organization has gone under and may not be able to pay its workers. What are some steps I should take to get what I am owed?
EDIT - I finally got a response; the director of the organization simply fell behind in paperwork and is late to processing invoices. So it appears the organization is still solvent and the other contractors and I are likely to be paid shortly. I'll of course leave this question up (answer accepted) in case it goes this way for anyone else in the future). And it goes without saying that it's now on me to decide if I want to work with a group like this again...
