For some companies they still prefer to use postal services for gathering and sending information. It may be that you have been sent a form that needs to be completed and then returned to a company to be processed. Relying on the post can be a nightmare and cause unnecessary delays. It can mean that a form takes over a week to be received by client and then back by the sending company before it can start to be processed.
Many companies have moved forward with the times and actually allow forms to be completed online or printed, scanned and emailed back to them to speed up the process. Unbelievably, companies such as HM revenue and customs still do many processes by paper and their deadline are extremely vague because of using the postal service. They do state that it can take 2 weeks for a form to be printed and posted out to someone. Not only does this method of postage add unnecessary time to a claim but also adds cost for the claimant and HMRC.
