I have a use case, a user with several AWS accounts. Not all accounts/email addresses are known, not documented, change of staff. There is a bank card that is being billed. How can I determine which AWS account is generating the billing ?
Thanks for any assistance.
Take a look at the AWS Cost Explorer it allows you to see detailed information about the costs. You can see what services generated how much costs, on which account, in which region and much more with filter options.
There should be a Master / Management account if they are using AWS Organizations, and this will be able to see all child accounts through the AWS Cost Explorer Ausgefuchster mentioned.

I have an AWS account. There are multiple users being managed by IaM service.
Each user has access key and is at liberty to perform various actions such as files upload.
Is there any means to monitor cloud costs and usage by user?
I utilize cost explorer AWS service and intend filtering and grouping costs/usages by user. Unfortunately haven't come up with any way to nail it in the most graceful way.
One common way to do this is to use Cost Allocation Tags.
You can define these tags and enforce them, e.g. using AWS Config and/or tag policies.
AWS does not track costs by user.
When an IAM User makes a request to AWS to create resources (eg an EC2 instance or an RDS database), the user's permissions are checked to confirm that they are permitted to make that API call. If they are permitted, then the API call is allowed and the resources are created.
Resources created in an AWS Account are owned by the AWS Account, not an individual user. Thus, there is no relationship between resources and the credentials used to create the resource.
The closest link between users and resources would be the audit trail of API calls kept by AWS CloudTrail. CloudTrail stores information about the API call and the user that made the call, but it does not directly link to the resources that were created. This would take some effort to back-trace resources to users.
Typically, cost management is done by tagging resources. Such tags would identify cost centers or project codes that can be used to charge-back the cost of systems. Enforcing tagging is difficult. Only some services allow tagging to be enforced when services are launched. For others, it would be a matter of identifying resources that do not meet tagging requirements.

You can monitor every IAM user action through cloud trails logs. So you could imagine a solution based on those logs to calculate the cost of all actions from one IAM user
I allways recomend to have an account per user type or subscription type in your system (free or premium for exmaple). Depending on the user who use your services, you will login that use with this account. Then, using the AWS Cost Categories, you can to see the cost by users type, and then, knowing your number of users for each tipe or subscription you could know your price per user.
I am wondering if it is possible to see billing information through the Amazon SDK/APIs. Specifically, I want to see how much EC2 instances are costing the account. Is it feasible to have it break down by user if it is an IAM account, or breakdown by account if you are using consolidated billing?
I have seen ways of doing this by either creating an S3 bucket to have billing info dumped into, or using CloudWatch APIs which require the user to pay. Is there an easier way to get EC2 billing information through just API calls or the SDK?
Billing information can be provided as records in an Amazon S3 bucket. You can then analyze the content of those files to obtain the information you list.
It is not possible to obtain the billing records themselves via an API call.
See: Cost and Usage Report
(The older Detailed Billing Report is scheduled to be retired.)
In brief
We need to view AWS cost for resources created by a specific IAM user via aws:createdBy tag.
In full
My google search is not helpful - it gives me one idea to use Consolidated Billing for Organizations to have the view of cost-by-user billing but that requires to create separate AWS users, which again requires credit card.
Another solution I found is that we can view AWS cost by tag grouping via Cost Explorer report though we cannot find the mentioned tag createdBy as stated in that AWS guide?
The ideal solution should let us create as many IAM users as the number of projects may grow i.e. one IAM user per project; and then, give us the report of AWS cost for each of those users.
So, how can we get to it?
Costs are not incurred by IAM Users. The AWS Account owning the resource incurs the charge.
When an IAM User makes a request to AWS, their credentials are verified to ensure that they are the authorized person and their permissions are checked to confirm that they have permission to perform the operation. However, there is no further relationship between the person making the request and the resource that is created.
The closest connection is the audit log created by AWS CloudTrail that can show which user made each request. But this is not related to billing information.
If you wish to track costs, you should associate tags with resources. These tags could be based on department, cost center, person, etc. You can then configure your Detailed Billing Report to provide cost breakdowns by tag.
You could use a more concise solution systematically using your own tags by setting up Lambda, CloudWatch, CloudTrail, and SSM to achieve it.
Here are some references:
Automatically tag new AWS resources based on identity or role
GitHub - resource auto tag
I am searching for a solution to let the AWS IAM user only restricted information to the billing information, only that part they generated.
I think that is not a build-in feature, but is that possible to be implemented with services like cloudwatch ?
This is not a built-in feature indeed, and I don't think this can be achieved in cloudwatch.
A workaround is to split into multiple AWS accounts with one account been the billing account, using consolidating billing. That way, users can only see the billing from their "own" AWS account, but not the global billing from the billing account.
You could aslo do sth with the tags and use budgets on it, e.g setting a tag "owner" to your instances. You could thus get detailed billing.
I have domains, instances, and buckets open on my AWS account - some are running databases on them.
I can't pay monthly for all of these services, because some of them aren't my own - I did them as work for others. And rather than going through the hassle of transferring the compute and database to another instance on another account, I'd like an IAM user to pay with his/her credit card for the services he owns.
Can IAM users pay monthly for services on my AWS account? If so, how?
No. There's no mechanism for what you want.
You may be interested in Amazon DevPay, which is sort of like what you're asking for. But I think you're doing contract work for individuals and DevPay is aimed more at providing an AWS-like service atop AWS and selling it to other developers.
The other direction is to make your clients create an AWS account. If you want to be fancy, you could use Consolidated Billing to create a sub-account under your control but billed to the customer. I think this is the best fit for consulting work, but getting there from your current setup will be painful.
There are some services (S3, ..) where you can let the client pay per call, bu for the rest I believe that your account is only yours. What I do is presenting the detailed billing and I let the company reimburse the costs.
Maybe you will have to migrate the environment. If your clients are not proficient aws users, you may want to build a cloud formation script that would enable them to start and access the environment in a few clicks..
