In our country, Costa Rica, it is a mandatory requirement to generate an Electronic Invoice, which must be in accordance with the provisions issued by the Ministerio de Hacienda. There are multiple systems on the market, which, being systems that were developed before this legal provision came into force, therefore do not include this process.

The current process corresponds to

1. Create the electronic invoice, which must contain a series of established data, in addition to the items or services that are being traded. This file must be in format XML and must be signed with the certificate issued by the Ministerio de Hacienda.
2. The signed file must be sent to the Ministerio de Hacienda servers, so that it can be reviewed, processed and finally there are 3 options that the servers can indicate:
   1. Accepted Document.
   2. Partially Accepted Document.
   3. Rejected Document.
3. After receiving the response from the servers of the Ministerio de Hacienda, received in the previous step, which is contained in a response file, issued by the servers of the Ministerio de Hacienda, which is received in format XML. If the answer is the acceptance of the electronic document, the file must be created in format PDF, which must be sent to the end customer by email.

The entire process mentioned above, the developers or companies that are developing an electronic invoicing system, can decide between carrying out the development of the entire process or purchase a service like we offer, with which, you can simplify your work and thus focus your efforts on achieving optimal development, allowing us to take care of the constant changes and adjustments made by the Ministerio de Hacienda.
