How to Import Payroll Documents into A3Nom — AI Extraction Guide (2026)

Spanish gestorías and payroll teams spend hours every month manually typing employee data into A3Nom (a3asesor Nom) from Wolters Kluwer. Whether the source is a nómina, an IDC report from the Seguridad Social, or a contract amendment, the workflow is the same: read the PDF, open A3Nom, and retype every field one by one.

Inputo replaces that manual step. Upload the PDF or scanned document, let AI extract structured employee data — DNI, NSS, CCC, salary figures, and more — then download an Excel file formatted for A3Nom's native import. No templates to build. No column mapping by hand.

What is A3Nom and why does import matter?

A3Nom (officially a3asesor Nom) is Wolters Kluwer's payroll and labour management software, widely used by gestorías across Spain. It handles payroll calculation, Social Security filings (LCR, AFIA, RNT), contract management, and tax models (111, 190).

A3Nom supports mass data import via Excel files through its menu at Utilidades/Exportar/Importar/Importar Base de Datos. The challenge is not the import itself — it is getting the data into the correct Excel format with the right column names and field values. For a gestoría processing dozens of new hires every month, that means hundreds of fields to type manually from PDF documents.

What payroll documents can Inputo extract for A3Nom?

Inputo processes the most common document types Spanish payroll teams receive:

• Nóminas (payslips) — Employee name, DNI, NSS, gross/net salary, IRPF percentage, social security contributions, bank account
• IDC reports — Informe de Datos para la Cotización from the Seguridad Social. Contains CCC, professional group, contribution base, hire date, contract type
• TC1 and TC2 documents — Monthly contribution summaries with company CCC, worker count, and total contribution amounts
• Contract documents — Alta de trabajador forms with personal data, start dates, professional category, and work schedule
• AFFI reports — Afiliation files with employee NSS, DNI, and registration details

All of these arrive as PDFs — sometimes digital, sometimes scanned copies from a client. Inputo's OCR layer handles both cases, with support for Spanish-language document layouts.

Step-by-step: from PDF to A3Nom import file

1. Upload your payroll documents

Open the Inputo app and drag one or more PDFs into the upload zone. You can process a single employee's nómina or batch-upload a month's worth of documents. Supported formats include digital PDFs, scanned PDFs, and photos (JPG, PNG).

2. AI extracts structured data

Inputo's AI reads the document and identifies each field automatically. For a typical nómina, this includes:

The AI handles layout variations between different nómina generators, bank formats, and scanning quality. No per-template configuration is needed.

3. Review and verify critical fields

Before exporting, Inputo shows all extracted fields in a review panel. Fields with low confidence are flagged — typically handwritten annotations, blurry scans, or unusual layouts. Review critical identifiers like DNI and NSS before finalising. A single digit error in an NSS can cause rejections from the Seguridad Social.

4. Export to A3Nom format

Click Export to A3Nom to download an Excel file with column headers matching A3Nom's official import layout. The file is ready to import via Utilidades/Exportar/Importar/Importar Base de Datos in A3Nom without manual column remapping.

For batch processing, all employees from the uploaded documents are combined into one file — one row per employee — so a single import covers the entire month's new hires.

AI extraction vs manual entry for A3Nom

Manual data entry into A3Nom is the default for most gestorías. Here is how it compares to AI extraction at typical monthly volumes.

For a gestoría processing 100 employees per month, manual entry consumes roughly 15–25 hours monthly. AI extraction reduces that to 2–4 hours of review time, freeing staff for advisory work and client service.

Integrating Inputo with your gestoría workflow

Standard gestoría workflow

A typical Spanish gestoría receives client documents via email, WhatsApp, or a shared drive. The AI extraction workflow integrates into this existing pattern:

• Client sends documents — PDFs of nóminas, IDC reports, contracts arrive by email or portal
• Upload to Inputo — Drag files into the app or use the PDF to Excel converter for quick one-offs
• Review extracted data — Verify DNI, NSS, salary fields; correct any flagged items
• Export Excel — Download the A3Nom-formatted file
• Import into A3Nom — Use Utilidades/Exportar/Importar to load the data

For offices handling multiple clients, Inputo also supports batch processing — upload documents from several companies in one session and export separate files per client or a combined file per CCC.

Multi-country payroll offices

If your gestoría also manages Italian, Portuguese, UK, or French payroll, Inputo exports to TeamSystem, PHC GO, Moneysoft, and Silae using the same upload-and-review workflow. The seven-language OCR covers all supported markets without additional setup.

Common challenges with A3Nom data import

Column format mismatches

A3Nom expects specific column names and data formats in its import Excel files. A date in the wrong format (DD/MM/YYYY vs YYYY-MM-DD) or a missing leading zero in CCC will cause import errors. Inputo's A3Nom export template handles these format requirements automatically — dates, numbers, and identifiers follow A3Nom's expected layout.

Duplicate employee detection

Importing the same employee twice creates duplicate records in A3Nom. When you upload a document for an employee that already exists in your export, Inputo flags it for review before adding a duplicate row.

Scanned document quality

Client-submitted scans vary in quality. Blurry mobile photos or faxed documents produce lower OCR confidence. Inputo flags these for manual review rather than guessing — better to verify a field than import a wrong DNI or NSS into A3Nom and face rejection from Social Security.

Multiple CCC codes

Gestorías managing several companies work with multiple CCC codes. Inputo preserves the CCC per document so exports can be filtered or separated by company code before importing into the correct A3Nom database.

Frequently asked questions

Conclusion

Importing payroll data into A3Nom does not have to mean retyping every field from every PDF. AI extraction reads the document, identifies employee data, and generates an Excel file that A3Nom accepts directly — for nóminas, IDC reports, contracts, and affiliation documents.

Whether you are a solo gestoría processing 20 employees per month or a larger office handling hundreds, the workflow is the same: upload, review, export. No templates. No manual column mapping. No copy-paste errors in DNI or NSS.

For multi-country payroll offices, Inputo also exports to TeamSystem, PHC GO, Moneysoft, and Silae using the same process. One platform for all your payroll document extraction.
