They may also be practicing the holiday payments. Some companies will pay 45-60 days after a shop so potentially shops done in October may not get paid until December, but for the holiday season they will pay weekly, bi-weekly, or monthly meaning you could get paid for shops you did just a few days ago and then still wait two months for shops you did last month.
I dunno if NF is one of these companies, but I've had it happen with several companies last year. And then many companies will also do their best to get as much paid to you before December 30th for the taxes and such, too.
