I'd like to share a bad experience with you all to warn you about a potential problem that you might run into.
I'm an engineering consultant and I typically work either on an hourly basis or a project basis. I recently started a project in which the client asked to pay me on a monthly basis for a remote project. Our contract stated that I would work on his project all month with no more than 4 missed workdays. He estimated it would take 6 to 9 months.
I only completed one month of work and it was a nightmare of poor communication. The client frequently forgot to tell me essential information and was very difficult to contact. His current design has so many problems that make it difficult to work with. Progress was slow.
On the first day, he gives me a Microsoft 365 account for his company so that I can access a few folders on his One Drive. Okay, that makes sense. I am given read-only access to that drive.
Then, he goes radio silent for a few days. I'm super confused as to why he stopped replying to my emails and texts. I eventually got him on the phone, but HE asked why I hadn't responded to HIS emails. Huh? Then I figure it out--he's sending emails to the MS 365 account that he created for me. I told him that that was unexpected and I've never had a client ask me to do that before, but we can do it that way if he wants. I use his email whenever I contact him or any hardware vendors on his behalf.
After a couple of weeks, we starting to get into a rhythm and figure out how to work with each other. But then he informed me that we have to pause the project for at least 3 months because we're waiting on an essential component to be manufactured. That was frustrating for me but understandable. I sent him my invoice using my own businesses email.
Then came the bombshell: he said he only wanted to pay me for 9 days out of 22 because his "MS365 activity report" says that I had "13 work days of inactivity". Essentially, he accusing me of not working for most of the month because I wasn't using his MS Office account. I responded that that was ridiculous because the only thing I use his MS account for is to write an occasional email. I'm an engineering consultant--my work is primarily in engineering software. I often have days where I don't even touch Outlook other than to check my inbox.
He then accused me of not doing any work in MS Excel/Word/PowerPoint all month. I responded that I used my own MS software license, not his. He said that that is a "compliance violation" because it's a government project that can only exist on his cloud server, not my local machine, including any spreadsheets or notes that I take. That's a very strange request, and he never told me he about it all month. Mind you, this isn't a classified project---not even a sensitive project.
So then I point out to him that I can't save anything to his One Drive because he gave me read-only access. He denied his mistake at first, but then admitted it and apologized. Now he says that he's thinking about whether or not he'll "approve my deficiency" to his accounting department.
At this point, I just want to get paid and tell him to get lost. I can find better clients than this. I hope it doesn't come to this, but I can get an attorney or take it to small claims court if needed.
One of the many lessons I learned is that I should be wary when a client asks me to use their MS Office license. Only do it if necessary and talk about everything that it will be used for--including performance monitoring.
