  2. You will attend the SAT office closest to your home.

  3. You must carry:
  • Proof of CURP or Birth Certificate
  • Proof of address
  • Official identification valid

After 30 days you will have to attend the SAT office again to process these two files that are mandatory, as well as the password they provided you when you signed up; the signature and the seal They will help you sign your invoices and make your annual returns if required.

Step 3: Start Billing!

From now on you can request invoices for your expenses and also to issue invoices to your customers, it is important that you carry out this action because when filing declarations regardless of the period you are bound to, they will help you have a tax calculation with truthful information.

At this point I advise you to avoid having errors in your accounting, tax calculation, uncontrolled invoices, etc.. hire a good electronic billing system To support you in the realization of the entire financial status of your company, believe me that it will be too useful.

The SAT billing system has no cost, however, when you are familiarizing the interface of the page it is not so friendly and will only cause I diverted your time on how to make an invoice that if you do not succeed you only get frustrated compared to the benefits that a provider offers you.

In contrast, the advantages of investing in a billing system provider are that you allows you to optimize your time and that in addition to the control you will achieve in your company, you will have the company of experts in the field, dare to try!

As you noted in the previous steps it is not really complicated to register a natural person, so you have to follow the same steps for both natural and moral person, and if your company is small and performs some type of activity that does not require Title will be just as easy.


The requirements to register a company in finance are not really difficult, you should only go with the documents requested by the SAT to speed up the registration to the SAT and begin to have the benefits that this represents.

Those who have asked me how much it costs to register a company on the SAT have always shared that This procedure is free, it is a right that you have as a citizen, it is also admirable that even if you are not sure that your business will work you want to comply with the law.

I conclude with this question that you have asked yourself at the beginning of this post: “what should I do to register for the farm”, answer: “have the disposition to comply with the requirements of the law”.
