Most good courier companies like http://www.pcamasters.com/ recognize the importance of speed and convenience of courier services for regular companies, and low prices for E-commerce companies.
Regular company deliveries
Many regular companies that utilize courier services in Singapore do so because of the sheer convenience (they do not need have their own dispatch rider or ask an employee to spend his working time delivering goods or documents instead) and most of these documents are relatively urgent and needs to be delivered to a certain location or locations within a timely fashion. It is important to use courier services instead of getting your staff to deliver items for a myriad of reasons. There is an opportunity cost whenever you get your staff to go out. If you were to get a salesperson to deliver goods themselves, they would have wasted precious time that they could have put to use calling more people and getting more sales. If you were to get an administrative or operations staff to deliver it, you would be slowing down operations slowly over time! And if you were to deliver the documents yourself and spend a total of over 1 hour to and from the destination, you waste precious time and effort that could be put to further growing your business or at least finishing your workload before your weekends!
E-commerce deliveries in Singapore
Most E-commerce companies would need to keep the costs reasonable so that they can still maintain a healthy profit margin per product that they deliver to their customers. Therefore, if the costs were too high, the business would fail. However, the good thing is that as your business grows, the cheaper the delivery services would be because most courier companies charge much cheaper prices for companies with a high volume of deliveries per month.
Although Singapore may be considered small and densely populated, delivering hundreds and thousands of goods to your customers is no laughing matter. There are lots of logistics matters that has to be taken into consideration when you are doing that. Therefore, it is much easier to simply outsource everything for a still reasonable price. Save your time and put that extra time that you have into growing your business more and doing the things that actually matter and will help you get your business to where you need it to be.
