The blank paper stamped with the company's official seal and financial seal has legal effect; if the IOU or IOU is printed on a computer and stamped with the company's official seal and financial seal, its legal effect will be clearer and can be used as Economic transaction certificate.
The reason why units or companies stamp official seals and financial seals on white paper is to avoid unnecessary waste of time caused by forgetting to bring the official seal or financial seal when making contracts in the future. However, if the official seal and financial seal are stamped on the white paper, no matter what content is added in the future, it will have legal effects, so try not to stamp the official seal and financial seal on the white paper.
