I have done freelance work for a local company in Reno, NV. I managed and created content to post on the company's facebook page. The marketing lady processes my invoices for payment but the company owner writes the checks. When I quit this job, I sent an invoice to reflect the number of days in the month that I had managed the page before quitting.
The marketing lady stated in email, "I would prefer that you to submit to me a flash drive with a comprehensive library of photos, graphics and testimonials inclusive of all images that have appeared on Facebook, and all images that have been provided to you by me. Upon receipt of that material, I will process your invoice for payment." I emailed back the marketing lady that the flash drive is ready. She replied that she will review flash drive and let me know about a check for this last month.
Am I obligated to give a flash drive to get payment?
