We needed to deliver a small boxes to all the location of our customer. We were obliged to ensure the delivery of the boxes in the agreed date and sort time slot. We contracted a world-known shipping company. As the life showed us the shipping company was not able to keep the dates and time preciously and unfortunately it was also not exactly mentioned in our contract with them. We had to cancel the contract and hire another shipping company with precious define obligation.
Late delivery of boxes caused delay in installation of the systems at customer sites, frequent work around - lot of stress on our side, permanent change of the installation plans and last but not least unsatisfied customer.
