Before you start registering your company, make sure you have the following items on hand:

  1. Valid electronic signature and password.
  2. Password for the electronic mailbox (SIEC)
  3. Email of the person who will receive notifications from bFiskur® 

Step-by-step instructions to add a company


To add a company, use the following steps.

  • Step 1: Log in to bFiskur® 
  • Step 2: Go to my RFCs and add a new company
  • Step 3: Add the FIEL of the company
  • Step 4: Configure the download parameters for your company
  • Step 5: Save and activate the company
  • Step 6: Verify that the download of historical information has finished.


At the end of these 7 steps, your company should be activated.


Step 1: Log in to bFiskur®︎

To access, you need your username and password, which you should have received when signing up for bFiskur®︎, to enter the platform.


Go to the following link:

https://bitam.com/login.php

and click on the top right, then enter your username and password and click on "log in"



Step 2: Go to my RFCs and add a new company

On the main screen, click on the My RFC icon
click on the icon (+) to add a company.


Step 3: Add the company's FIEL

Enter your company's FIEL. (You should not use digital seals but the FIEL)


Step 4: Configure your company's download parameters

You will need to configure the following basic parameters to set up your company.
Load range for history:

Monthly=bFiskur®︎ will read one month of history from the SAT at a time

Weekly=bFiskur®︎ will read one week of history from the SAT at a time


The suggested optimal value is Monthly.

Note: the value depends on the volume your company handles. Use monthly if the total sum of the number of issued + received CFDIs + payment complements + payroll receipts + waybills does not exceed 200,000 CFDIs. If your company exceeds 200,000 total CFDIs per month then use weekly.

In business group the name of your contracting company from bFiskur®︎ will appear exactly as it was registered on the platform. Select it from the list

In Short Name write a short name for the company you are adding. This name will be used to identify it in the different reports from bFiskur®︎. The name must be unique and cannot be changed later.
Specify here from when you want to download history. Keep in mind this parameter, it must be according to your contracted plan to avoid exceeding limits that may generate extra charges on your bill.

This parameter can be modified later.
Use "Yes" to download CFDIs, use "No" if you only want to download "Declarations"

Suggested optimal value: Headers only


Decide whether to download notifications and communications from the SAT. Keep in mind that when notifications are downloaded to bFiskur®︎, the SAT considers them read, thus starting the legal deadline to present the requirement. We suggest using "Headers Only" to receive notices of new content in your tax mailbox without implying that the SAT considers them read.


If you do not want bFiskur®︎ to download notifications, use No.

The latter is the default value shown in the image

The basic parameters are shown here. There are more parameters that can be configured at any other time; to add and activate a company, simply fill in the fields listed here.


Step 5: Save and activate the company

Once you have filled in all the parameters from the previous steps, save. This will activate the company.

When saving, bFiskur®︎ will validate that all data is correct and will activate the company immediately.

If an error occurs when saving, make sure not to use digital seals instead of the FIEL. Also, check that the short name of the company you are using is not already registered in bFiskur®︎.
Once saved, you can verify that your company has been activated by checking the section Company Data. If the company name appears there, then congratulations! your company has been activated and bFiskur®︎ will start the download immediately.
