Why does a customer conclude a long term project on Upwork with a one-time order?

Question

Freelance

Hello, I'm new to upwork and just took my first order. Initially, there were misunderstandings, but everything seemed to be resolved. Project with a fixed price by the way. After the customer dropped the offer, he said that he had entered into a long term. I roughly know what it is, but the work is clearly not for three months, but most likely three days.
Why did he do it? and perhaps a dumb question, but will he now pay for the work that I have done and for which he asked?
I would also like to ask if there is an offer, do you need to protect yourself and send him finished works with a watermark? or he can no longer deceive me?

Answer 1

threw off the offer, he said that he had concluded a long term.

What do you mean he said? You have a fixed price job (by the way, at the moment of opening this task, the money is debited from his card and the upwork is blocked), this is necessary and sufficient. Apparently, he had something in mind .. like we will cooperate with you and more, but I'm not sure, it depends on the context of your agreements with him .. It is quite possible that there will be more milestones within the same task, the client can add them in the future.
After you have done the work, press the button to request money. Why can't you pay? Any concerns?
Did you look at the reputation and profile of the client? Are there any reviews about it? How long has it been working? Is the payment method verified? Any doubts and here it is

Initially there were misunderstandings

interpreted not in his favor)
Do you understand by this exactly offer in terms of upwork? IMHO, the offer must first be turned into a Job, confirming it. Without this, do not even start work.
If you are engaged in graphics, before payment, you can throw off the result with a watermark or in a worse quality. But then again, if there are concerns, often this is simply not necessary.

Answer 2

Regarding fixed-price contracts - your work consists of one or more milestones (stages).
The customer, entering into a contract at a fixed rate, creates and deposits funds for at least one milestone - this amount will be visible on the "Milestones & Earnings" tab in the "In Escrow" column of your contract. Please note that the client can often deposit not the amount that you agreed with him. That is, if you agreed to complete the work in one stage, make sure that the entire amount is deposited.
According to the process of work, it is completely normal to give the customer draft versions of worse quality or with watermarks.
When the work is completed, you must send it to the customer by clicking on the "Submit Work for Payment" button. We are waiting for the client's response. There are three options here:
1) The customer confirms the milestone. You receive money in 5 days.
2) The client asks for edits. Make edits and resubmit.
3) The client is frostbitten and does not respond. After 2 weeks, Upwork will automatically credit the deposited amount (that's why it's important to always check it!) to your account.

Answer 3

If the "why" is completely abstract, then this is obvious - the customer needs to plan a budget, request investments, and so on. And longterm in this regard is a more reliable and profitable option than a bunch of one-time jobs. Investors do not like to be scattered over trifles.
Well, specifically, you need to ask the customer.
Judging by your "said that he concluded," it may seem that he did not conclude with you at all.
