Most businesses use business checks, which are written out of a specific business account. Not just anyone can write business checks, instead there is a process that each bank requires to add individuals to the account that are authorized to write checks. If everyone that worked for a business was allowed to just take the business account and write checks, that would cause a problem in bookkeeping, and it would be hard for the bank to keep track of who was allowed to write on the account and who was not.
Arranging to use business checks generally isn't all that difficult. First, the business must open an account with the bank. This typically isn't all that hard, and most banks don't require any more than they do for a personal account. The business will then order their business checks, which when cashed will be deducted from the business account. Before the checks are cashed, the bank will make certain that the signature on the check matches up with one of the authorized check writers on the account.
When arranging for a new person to use the business checks, they will generally have to go into the bank with the main account holder. The bank will likely take copies of their driver's license and with just a signature or two they will be authorized to write checks on the account. Arranging to use business checks just takes a little bit of time, and while it may seem inconvenient, it's easier to just get it done with so you can have all the people you need writing checks on the account.
