It is often the case that a modern business must engage in some fairly strict tracking of the packages and communications sent between various business entities and although no one likes to be on the losing end of a business argument, it's a good idea to employ digital tracking solutions when sending important communications between businesses because if something gets lost, it's easy to blame the other guy when things go wrong. Utilizing something like courier software can ensure that if a breakdown in delivery or communication happens that the point at which communication was lost can be easily found.
