What is internal financing

Internal financing, as its name suggests, is composed of those financial resources that companies produce by themselves. There are two types of internal self-financing:

1 – Self-financing of enrichment

It's about the resources obtained as a result of the economic activity of the company, this type of resources or goods is also often called reserves.

These types of reserves are intended to increase the productive capacity of the company. The causes that influence this type of self-financing and, as a consequence, the economic development of the company are the profitability of the investment, the cost of debts, the profit retention policy, and taxes, among others.

2 – Self-financing of maintenance

It's about the resources resulting from provisions and productive amortizations. The purpose of this type of resources is to maintain the value of the assets to guarantee the development of the company with the preservation of its patrimony.

What is external financing

The external financing is required when the company does not have sufficient financial resources for the continuity of your business activity. As we all know, a lack of liquidity at a given moment does not mean that the company is not viable or profitable, only that at that moment it does not have liquidity and therefore needs external resources to continue. There are two types of external financing:

1 – Own sources of financing

They are those financial resources that, despite coming from abroad, since they are not the result of the business's own economic activity, are considered the company's own resources, since the return of these resources is not mandatory. It is the case of issuance of capital by the partners of the company.

2 – Outside financing sources

Are those financial sources that are obtained from outside the company and? are characterized by the return of these assets with interest, repayment terms, contractual payments and priority in case of solvency.

Included in this category are equity Instruments, through contracts in which the company negotiates a residual participation in its assets, this is the case of the issuance of shares. And the Debt instruments, through contracts that represent a monetary benefit that will be returned to the supplier within a stipulated period with an interest cost.

In this type of financing, external approval is not required, so there is more independence and speed when deciding what does not require guarantees or endorsements, although a second assessment in terms of return on investment is always good.

Since it involves internal resources, this type of financing does not imply any consideration, disbursement or interest to any other organization, this means greater profitability by reducing financial, banking or administrative expenses.


Use internal financing sometimes means running out of own resources to face difficulties that may arise in the short term.

It must also be taken into account the opportunity costs involved financing with the company's own resources, since we must assess the consequences both in the short and long term, and take stock of the liquidity and profitability of our economic activity.


external financing


Regarding external financing, it is very recurrent since companies do not always have sufficient own resources that allow them to finance their projects.

External financing entities are usually useful since they give a second vision of profitability and opportunities that provides the financing of a project, on the other hand, are also effective since they are impartial and independent bodies.


One drawback of this type of financing is that comes with a cost, that is why it is important to weigh the costs-benefits, as well as the profitability analysis of the financing.

Leaving the financing of your projects in the hands of another organization does not imply increased reliance on decision making, and on the other hand, it also requires more time due to the technical and legal procedures of this type of operation.


Before making a decision, we recommend that you do a good analysis of the economic situation of your company, to assess the advantages and disadvantages represented by each of the sources of financing. He thinks that there are no master formulas and that each type of financing can be ideal at one time or another depending on the situation of your company or the business project you wish to undertake.

A good solution may be to combine both instruments, both the internal resources of your company, as well as external financing resources. In this way you will not exhaust all your internal resources and you will not be fully dependent on external financing.
