There are many businesses in Singapore which sell products. Unlike services, when it comes to products, you either need to deliver it to your customers or have them pick it up. Chances are, unless you have a retail store / operate a retail store, you will need to deliver your goods to them either via a courier, a driver or a salesperson.
Of course, these are 3 ways in which you can do it, but which way is the best in terms of financial and business efficiency?
First of all, if you have a courier, for example outsourced courier services, you will usually have various levels of services provided by them. You can always opt for their regular one (which is generally speaking either same day or next day delivery) or you could opt for their fast parcel delivery in Singapore level of service which is provided by most courier companies in Singapore. That way, you can deliver urgent goods to your customers. They are usually the choice of businesses which want to lower their fixed overheads (which will be the case if you were to hire drivers).
Secondly, if you were to hire drivers, you would definitely have much higher fixed overheads because of their fixed salaries as well as purchasing or leasing a vehicle for parcel or document deliveries.
However, the good part about having your own drivers is that you have greater control over the employees. This is however only a good choice if you can also pay them lower than a courier services company in Singapore would charge; otherwise you would be better of outsourcing to a courier company because they are also reliable.
Finally, you could also get your salespeople to distribute the product. This is the common way many network marketing companies have done it such as Amway. They distribute products through their agents.
No matter which distribution model you choose, make sure you choose one which fits your business requirements, strengths and constraints.
