Talking about Internal & External Economies of Scale, hence making clear that the digital economy can help create an impressive environment with almost zero cost that can fit "economies of scale" in the future, with an investment of course!

What Are Economies of Scale?

Economies of scale are cost advantages reaped by companies when production becomes efficient. Companies can achieve economies of scale by increasing production and lowering costs. This happens because costs are spread over a larger number of goods. Costs can be both fixed and variable. 

The size of the business generally matters when it comes to economies of scale. The larger the business, the more the cost savings.

Economies of scale can be both internal and external. Internal economies of scale are based on management decisions, while external ones have to do with outside factors.

Understanding Economies of Scale

Economies of scale are an important concept for any business in any industry and represent the cost-savings and competitive advantages larger businesses have over smaller ones.

Most consumers don't understand why a smaller business charges more for a similar product sold by a larger company. That's because the cost per unit depends on how much the company produces. Larger companies are able to produce more by spreading the cost of production over a larger amount of goods. An industry may also be able to dictate the cost of a product if there are a number of different companies producing similar goods within that industry.

There are several reasons why economies of scale give rise to lower per-unit costs. First, specialization of labor and more integrated technology boost production volumes. Second, lower per-unit costs can come from bulk orders from suppliers, larger advertising buys, or lower cost of capital. Third, spreading internal function costs across more units produced and sold helps to reduce costs.

Internal functions include accounting, information technology, and marketing. The first two reasons are also considered operational efficiencies and synergies. The second two reasons are cited as benefits of mergers and acquisitions.
