On the issue of government procurement contracts regarding the free maintenance period of the vendor's products

Because the warranty period for the products or services required in the bidding of our government procurement projects starts from the date of acceptance, the bidding party should take this aspect into account when calculating the bidding price.

The government procurement contract is based on the bidding documents and tender documents, in principle, does not allow changes, and if the warranty is changed to the date of delivery, it is clearly unfavorable to the purchaser, the purchaser may agree to modify how it?

Because even if you deliver, but the purchaser has not been accepted, who can guarantee that your products are qualified no problem? The warranty must be calculated from the date of acceptance.
