All official documents, as well as contracts, invoices and acts, which are signed during work activities, are sealed. There are several types of stamps, each of which is designed for different securities.
Official seals are used to seal documents received from government agencies. Technical requirements for their location, print size, words and symbols are set out in the state standard GOST R 51511-2001. Only authorized organizations have the right to use such stamps. Commercial firms and individuals are not allowed to seal securities with official seals. This stamp is put by an employee of a state institution without any interference from the person for whom the documents are prepared.
Commercial organizations have round stamps equivalent to official ones. To seal the document with it, wait until it goes through all the approvals and is signed by the CEOs of both parties. Then open the contract on the last page. Find the section with company details. They are signed by the responsible persons. Put a seal so that part or a whole print will be included in the list, surname, name and patronymic of the general director. Wait for the ink to dry. Only then can the sheets be folded together. Do not forget to put stamps on all attachments to documents and on the details of partner companies.
All financial documents, acts and invoices where the CEO's signature is absent shall be stamped with a round seal. Its imprint must be present on the signature of the chief accountant or other person authorized to approve these securities.
A square stamp does not have the same strength as a round stamp. It is used to determine the ownership of a document. For example, there may be written the name of the department that issued it, or even the name of the employee whose duties include the maintenance of such contracts. It is usually placed on the first page so as not to touch the text.
