Simplified Transactional Annex (ATS)

What it is and what it's for

The ATS pulls its data directly from documents you've already recorded (invoices, notes, exports and voids) — there's no need to type the information again. The report screen shows four tabs with a preview of what will be included in the final file:

Purchases

For each purchase document it shows the vendor (identification type and number, legal name, whether it's a related party), the document data (establishment, emission point, sequence number, authorization and dates), the taxable bases and taxes (base not subject to VAT, 0% rate, non-zero rate, VAT-exempt, ICE special-consumption tax and VAT), the withholdings applied by type of good or service (10%, 20%, 30%, 50%, 70% and 100%), the withholding receipt data and, when the purchase corrects an earlier document, a reference to the modified document.

Sales

For each sales document it shows the customer (identification type and number, legal name, customer type, whether it's a related party), the document type and its emission mode (online or offline) with the quantity issued, the taxable bases and taxes (base not subject to VAT, 0% rate, non-zero rate, ICE, VAT) and the VAT and income tax that third parties withheld from you.

Exports

Details your export operations: the customer abroad and their tax regime, the country of effective payment, whether the income was taxed in another country and the tax paid there, the customs data (district, regime, sequence number, transport document, shipping date and FOB value) and the related sales document data.

Voided

Lists the receipts you voided during the month, with their type, establishment, emission point, the voided sequence range and its authorization.

How to use it

1. Open the report from Accounting → Fiscal Reports → ATS.
2. Choose the Year and Month to declare. The current year and month are shown by default.
3. Pick the Subsidiary if your company runs multiple currencies by subsidiary; it's required in that case, so the report doesn't mix amounts from different currencies in a single total.
4. Click Refresh to load the four tabs (Purchases, Sales, Exports, Voided) on screen with the data for the chosen period.
5. Check the errors column on each tab. Lines flagged with an error point to data the SRI would reject; fix them on the original document and refresh the report again.
6. Download the file with the Generate and Download XML File button. AdmCloud automatically names the file AT-MMYYYY.xml (for example, AT-012025.xml for January 2025).

Key fields

Validations and warnings

• Only your subsidiary: if your user group is assigned to a subsidiary, the previews and the XML file only include transactions from that subsidiary; picking another subsidiary shows a no-access message.
• Subsidiary required: if your company has subsidiaries in different currencies, you must pick one before generating the file, so the report doesn't mix amounts from different currencies in a single total.
• No errors on any tab: the XML file isn't generated if Purchases, Sales, Exports or Voided has any line flagged with an error; the message tells you which section has the problem so you can fix it first.
• Valid company tax ID (RUC): it must have 13 characters and end in "001" (main establishment). If it doesn't, the download stops with the message "The RUC is invalid".
• Company legal name: must be between 5 and 500 characters; otherwise the file isn't generated.

Availability and conditions

• The ATS report is only available for companies configured for Ecuador, since its structure and catalogs are specific to SRI regulations.
• Access is controlled by the General Ledger Journal permission (GL_JOURNAL).
• Requires your company to have a valid tax ID (RUC) and legal name configured in Company Configuration, since both are included in the header of the generated file.
• If you use Electronic Invoicing, AdmCloud automatically pulls the data from your configured gateway to complete the receipt information in the report.
