First and foremost, I am happy to say that it appears I do not have a cold--I'm just extra-sensitive to climate changes, and we had a doozy of a change this weekend. So hooray and thanks for the well-wishes.
When I started my 20-hour-a-week-not-a-part-time-job gig, I also started using their payroll system to track my hours and the amount of time spent of each of their clients' projects. Logically, I assumed that because I was using their payroll system, and submitting weekly time sheets to accounting, that meant I would be paid via their payroll system rather than invoicing them like I have in the past. Three weeks into the project, the accountant needed me to change "accounts" within the payroll system, and asked me to create an invoice for my first two weeks. I did, and I got a check.
Fast-forward to late last week, when I realized I haven't seen another check since that first one. So Monday I asked the CEO when I could expect to be paid for the rest of October and the first week of November--and boy am I glad I spoke up! Apparently, they were expecting me to invoice for all my hours. They use what I enter into the payroll system for billing their clients, but aren't paying me based on that.
As if I needed further proof what a great client this is, the CEO offered to cut me a check right then and there. I told him that wasn't necessary, and that I'd just go ahead and submit an invoice.
