Every entrepreneur who enters the field of e-commerce, sooner or later will have to learn how to calculate freight from the Post Office. In fact, there are basically two ways to do this, one manual and one automatic.
While the manual way can be used in the most rudimentary e-commerces, that is, that are in the testing phase; automatic should be used in e-commerces that are already well developed.
Then, in this same article, you will know a little about these two procedures.

HOW TO CALCULATE POSTAL FREIGHT: THE RUDIMENTARY WAY
To learn how to manually calculate shipping costs with Correios (Brazilian postal service), simply go to the company's website called " Price and Delivery Time Calculation ".
On this page, you have access to the following services:
- Calculator of National Prices and Deadlines;
- Calculator of International Prices and Deadlines.
Once on that page, click on the desired option.
To determine the shipping price of a product in the national territory, for example, you must first enter the origin zip code and the destination zip code.
After that, choose the type of shipping service.
Then choose the format and packaging.
Next, specify the estimated weight of the order.
Finally, select the optional services you want and press the “Submit” button.

Once this is done, the calculator will show you the price options and delivery times for the order on an extra page.
So, just include the shipping to the product and inform the final price to your customer.
Note, however, that this tactic only works when e-commerce is in a very early stage, with very few customers.
Therefore, if you have an e-commerce business that has already passed this stage, the ideal solution is to start using an automated calculation system, that is, a shipping gateway.

UNDERSTAND WHAT FREIGHT GATEWAY IS
Freight Gateway is a system that integrates multiple modes and transport companies into an e-commerce platform.
But more than just integrating, this system also automatically performs the calculation and exposes, in a matter of seconds, to your online store customers, the shipping price of the product they are trying to buy.

In other words, when a customer enters the zip code in your online store, the gateway calculates and presents the best options for prices and delivery times. From then on, the customer just needs to choose the best alternative for him and proceed with the payment for the purchase.
That is, with the gateway there is no need to calculate anything manually.
In addition, through a freight gateway it is also possible to:
- Manage contracts with carriers and delivery companies;
- Work with several delivery companies (not just the Post Office);
- Manage and update different freight price tables with practicality;
- Calculate the freight price automatically, quickly and accurately;
- Avoid errors that usually occur during manual freight calculation;
- Provide your online store customers with multiple shipping offers;
- Compare shipping prices and choose the best delivery companies;

- Link promotions to your product deliveries.
