Hello! Please help.
I want to know whether Yur. point of view to prescribe the liability of the contractor for errors.
Situation: our company has a website selling parts. Working on 1C Bitrix.
The problem was that "hung out" basket and no exchange between the site and 1C. The contractor said that the problem is in the old platform of Bitrix and offered to update it. After upgrading all the units of our company checked out your site and shut down work.
After a few months, one Department found that some parts were given a double discount. As a result, the firm lost several million.
Explanation: the calculation of discounts is on the side of the site, and 1C. In the "old" version of the platform the discount calculation on the side of the site was deactivated in manual mode by the Contractor. When you update this, apparently, they are forgotten.
Question - how in the future to prescribe the liability of the contractor for similar mistakes in his area of responsibility?
In the current contract provide penalties for failure of terms of execution and failure of the timing error correction, now this error "take money" from the Contractor will not work.
Thank you! I would be grateful, if will stick to the wording of existing contracts you have. Our lawyers are afraid to describe the word "error". Trying to help everyone, as a novice project Manager. Want to understand how to do it correctly.
