 DIOT Report (Requires Accounting App)
 =====================================
 
-TODO
+**What is the DIOT and the importance of presenting it SAT**
+
+When it comes to procedures with the SAT Administration Service we know that
+we should not neglect what we present. So that things should not happen in Odoo.
+
+The DIOT is the Informational Statement of Operations with Third Parties (DIOT),
+which is an an additional obligation with the VAT, where we must give the status
+of our operations to third parties, or what is considered the same, with our
+providers.
+
+This applies both to individuals and to the moral as well, so if we have VAT
+for submitting to the SAT and also dealing with suppliers it is necessary to.
+submit the DIOT:
+
+**When to file the DIOT and in what format?**
+
+It is simple to present the DIOT, since like all format this you can obtain
+it in the page of the SAT, it is the electronic format A-29 that you can find
+in the SAT website.
+
+Every month if you have operations with third parties it is necessary to
+present the DIOT, just as we do with VAT, so that if in January we have deals
+with suppliers, by February we must present the information pertinent to
+said data.
+
+**Where the DIOT is presented?**
+
+You can present DIOT in different ways, it is up to you which one you will
+choose and which will be more comfortable for you than you will present every
+month or every time you have dealings with suppliers.
+
+The A-29 format is electronic so you can present it on the SAT page, but this
+after having made up to 500 records.
+
+Once these 500 records are entered in the SAT, you must present them to the
+Local Taxpayer Services Administration (ALSC) with correspondence to your tax
+address, these records can be presented in a digital storage medium such as a
+CD or USB, which once validated you will be returned, so do not doubt that you
+will still have these records and of course, your CD or USB.
+
+**One more fact to know: the Batch load?**
+
+When reviewing the official SAT documents on DIOT, you will find the Batch
+load, and of course the first thing we think is what is that ?, and according
+to the SAT site is:
+
+The "batch upload" is the conversion of records databases of transactions with
+suppliers made by taxpayers in text files (.txt). These files have the
+necessary structure for their application and importation into the system of
+the Informative Declaration of Operations with third parties, avoiding the
+direct capture and consequently, optimizing the time invested in its
+integration for the presentation in time and form to the SAT.
+
+You can use it to present the DIOT, since it is allowed, which will make this
+operation easier for you, so that it does not exist to avoid being in line
+with the SAT in regard to the Information Statement of Operations with
+Third Parties.
+
+You can find the `official information here`_.
+
+**How Generate this report in odoo?**

+
+Important considerations on your Supplier and Invice data for the DIOT
+======================================================================
+
+- All suppliers must have set the fields on the accounting tab called "DIOT
+  Information", the *L10N Mx Nationality* field is filled with just select the
+  proper country in the address, you do not need to do anything else there, but
+  the *L10N Mx Type Of Operation* must be filled by you in all your suppliers.
+
+.. image:: media/mexico22.png
+   :align: center
+
+- There are 3 options of VAT for this report, 16%, 0% and exempt, an invoice
+  line in odoo is considered exempt if no tax on it, the other 2 taxes are
+  properly configured already.
+- Remember to pay an invoice which represent a payment in advance you must
+  ask for the invoice first and then pay it and reconcile properly the payment
+  following standard odoo procedure.
+- You do not need all you data on partners filled to try to generate the
+  supplier invoice, you can fix this information when you generate the report
+  itself.
+- Remember this report only shows the Supplier Invoices that were actually paid.
+
+If some of this considerations are not taken into account a message like this
+will appear when generate the DIOT on TXT with all the partners you need to
+check on this particular report, this is the reason we recommend use this
+report not just to export your legal obligation but to generate it before
+the end of the month and use it as your auditory process to see all your
+partners are correctly set.
