1. Unrealistic Prices: The prices listed for popular and high-demand software and game keys are significantly lower than market prices. This is a common tactic used by scam websites to lure in unsuspecting customers with the promise of unbelievable deals.
3. Suspicious Payment Methods: The website may only offer payment methods that are difficult to trace or reverse, such as cryptocurrency or wire transfers. This can be a warning sign, as reputable online stores usually offer a variety of secure payment options.
5. Limited or No Customer Reviews: Scam websites often have limited or fabricated customer reviews. Look for independent reviews on trusted platforms to gauge the legitimacy and reliability of the online store.
6. Unprofessional Website Design: Poorly designed or unprofessional-looking websites can be indicative of a scam. Legitimate online stores typically invest in professional web design to build trust with customers.
8. Lack of Trust Seals or Certifications: Legitimate e-commerce websites often display trust seals or certifications from recognized security and business organizations. The absence of these can be a cause for concern.

It depends on the line of work. Usually, it's not safe.
Depending on how long this will take, you could let them use teamviewer use your software from your machine. But would need to watch while they do it or have a clean user account so you are sure they won't do anything to your PC.
Like Quickbooks? If you are giving a person access to your financial records for manipulation, then I don't see how providing the software license to do said manipulations will be an issue. You just need to make sure that you have the ability to deactivate their license, which you can do via the software company or possibly even simple product administration.
But if we're talking about giving someone you just knew access to your database, then there's a lot of cases in this forum that suggested you to take another precautions first, such as making sure you'll have a back-up. Here's a thread just bumped up below.
Bear in mind, that in any case, an accountant will be making financial statements on your behalf. But at least make sure that it is evident that they are made on your behalf. If you give them the product key it is going to appear as if they were made by you directly. I would think there is a difference there.
That 100% depends on the exact project and work. Most remote Quickbook accountants contain a license for each client on their computer as a CPA. Frequently there is no need for you to even have an accounting system. Check with your CPA for the specifics and ask for referrals.
Giving out your software product key and license should be done with caution, as it can potentially compromise the security of your software and data. Here are a few things you should consider before giving your software product key and license to a freelancer:
The nature of the software: If it's a proprietary software that holds sensitive information or data, it's best not to share the key and license. If compromised, your business could be at risk.
The credibility of the freelancer: If the freelancer has a good reputation, solid reviews, and a track record of working with similar software, it may be safer. Still, it's important to remember that you're trusting them with sensitive information.
The software's terms and conditions: Make sure to read and understand the software's terms and conditions regarding sharing license keys. You could be violating the terms of service by sharing your key with someone else.
Alternatives to sharing the key: Depending on the task, there may be alternatives to sharing your key. For example, if the task can be done using a screen-sharing tool or remote desktop access, this might be a safer option. Some software also allows for multiple users or for permissions to be granted to additional users.
You can do something like create a record which contains the data you want to authenticate to the application. This could include anything you want - e.g. program features to enable, expiry date, name of the user (if you want to bind it to a user). Then encrypt that using some crypto algorithm with a fixed key or hash it. Then you just verify it within your program. One way to distribute the license file (on windows) is to provide it as a file which updates the registry (saves the user having to type it).
Beware of false sense of security though - sooner or later someone will simply patch your program to skip that check, and distribute the patched version. Or, they will work out a key that passes all checks and distribute that, or backdate the clock, etc. It doesn't matter how convoluted you make your scheme, anything you do for this will ultimately be security through obscurity and they will always be able to this. Even if they can't someone will, and will distribute the hacked version. Same applies even if you supply a dongle - if someone wants to, they can patch out the check for that too. Digitally signing your code won't help, they can remove that signature, or resign it.
You can complicate matters a bit by using techniques to prevent the program running in a debugger etc, but even this is not bullet proof. So you should just make it difficult enough that an honest user will not forget to pay. Also be very careful that your scheme does not become obtrusive to paying users - it's better to have some ripped off copies than for your paying customers not to be able to use what they have paid for.
Another option is to have an online check - just provide the user with a unique ID, and check online as to what capabilities that ID should have, and cache it for some period. All the same caveats apply though - people can get round anything like this.
edit: I just want to add, don't invest too much time in this or think that somehow your convoluted scheme will be different and uncrackable. It won't, and cannot be as long as people control the hardware and OS your program runs on. Developers have been trying to come up with ever more complex schemes for this, thinking that if they develop their own system for it then it will be known only to them and therefore 'more secure'. But it really is the programming equivalent of trying to build a perpetual motion machine. :-)
I've always considered this area too critical to trust a third party to manage the runtime security of your application. Once that component is cracked for one application, it's cracked for all applications. It happened to Discreet in five minutes once they went with a third-party license solution for 3ds Max years ago... Good times!
And since this is now probably the most important code in your application/company, on top of/instead of obfuscation consider putting the decrypt routines in a native DLL file and simply P/Invoke to it.
If you are asking about the keys that you can type in, like Windows product keys, then they are based on some checks. If you are talking about the keys that you have to copy paste, then they are based on a digitial signature (private key encryption).
A simple product key logic could be to start with saying that the product key consists of four 5-digit groups, like abcde-fghij-kljmo-pqrst, and then go on to specify internal relationships like f+k+p should equal a, meaning the first digits of the 2, 3 and 4 group should total to a. This means that 8xxxx-2xxxx-4xxxx-2xxxx is valid, so is 8xxxx-1xxxx-0xxxx-7xxxx. Of course, there would be other relationships as well, including complex relations like, if the second digit of the first group is odd, then the last digit of the last group should be odd too. This way there would be generators for product keys and verification of product keys would simply check if it matches all the rules.
Encryption are normally the string of information about the license encrypted using a private key (== digitally signed) and converted to Base64. The public key is distributed with the application. When the Base64 string arrives, it is verified (==decrypted) by the public key and if found valid, the product is activated.
Personally, I think there are two classes of user. Those who pay. Those who don't. The ones that do will likely do so with even the most trivial protection. Those who don't will wait for a crack or look elsewhere. Either way, it won't get you any more money.

If you want a simple solution just to create and verify serial numbers, try Ellipter. It uses elliptic curves cryptography and has an "Expiration Date" feature so you can create trial verisons or time-limited registration keys.
Since you mentioned wanting 2 "types" of licenses for your application, i.e. a "full version" and a "trial version", we can simplify that and use a feature license model where you license specific features of your application (in this case, there's a "full" feature-set and a "trial" feature-set).
To start off, we could create 2 license types (called policies in Keygen) and whenever a user registers an account you can generate a "trial" license for them to start out (the "trial" license implements our "trial" feature policy), which you can use to do various checks within the app e.g. can user use Trial-Feature-A and Trial-Feature-B.
And building on that, whenever a user purchases your app (whether you're using PayPal, Stripe, etc.), you can generate a license implementing the "full" feature policy and associate it with the user's account. Now within your app you can check if the user has a "full" license that can do Pro-Feature-X and Pro-Feature-Y (by doing something like user.HasLicenseFor(FEATURE_POLICY_ID)).
