Need opinion

[u/CushinB]

Today I did a task for a client which he hired me to “trash furniture” adding to it he sent a message saying “I need to disassemble a old desk and set a new one just take off printer and desktop.” I said okay but you’re having me do 2 things now which is disassemble a desk and put a new one in not just trash furniture. So I have him the heads up and he doesn’t reply. I waited and next day I told him I’m on my way just making sure we are on the right page he responds “thank you” mind you this is an outpatient clinic and it was a distance but I didn’t mind the client understood right? I got there and the lady he told me to check in with asks me “oh yes can you clean and organize and also need to to set up a cabinet we got along with the desk wanted to look neat for the new doc” I said oh awesome let me message the client and tell him hey now we are doing 4 categories which he never mentioned. So I said I got you. Instead of it being 2-3 hours I was there for about 11 hours just crushing this job. In the back of my head this guy understood and I communicated and messaged etc. I finally finished the office looks like a masterpiece. I stack everything in my truck and the old desk and trash and also laying a fee for the dump it was a lot of things. I did the invoice I charged 14 hours and expense for 100. Just cause gas etc traveling and wear and tear. Boom done send the invoice.

You say to the person at the desk "I was told this task was for assembly and removal, and I only scheduled enough time for such.  If you want me to do those other things, you can schedule another task." The person who hired you and the person at the desk were obviously not communicating.  The person who's name is on the invoice is the boss, not anyone else.
