Is it correct grammar the Vendors does not have?

No, that sentence is not grammatically correct. It should be:

The vendor does not have...

Here's why:

* Subject-verb agreement: "Vendors" is plural, but the verb "does" is singular. You need to use the plural form of the verb, "do."

* Article usage: You need to use the definite article "the" before "vendor" because it's likely you're referring to a specific vendor, or a vendor that has already been mentioned.

Here are some examples of how to use the sentence correctly:

* The vendor does not have the product in stock.

* The vendors do not have the necessary licenses.
