About this skill
Automated Client Listing for Belgian VAT
This skill automates the tedious preparation of the annual Belgian "btw-klantenlisting" (client listing). Instead of manually wrestling with pivot tables and spreadsheet formulas to aggregate sales data, this tool provides an automated Python-driven workflow to process sales journals into submission-ready summaries.
What it does
- Aggregates total turnover per Belgian VAT number from export files.
- Applies the regulatory threshold (default €250) to filter reportable clients.
- Standardizes VAT number formatting by stripping spaces and dots to prevent duplicate entries.
- Identifies and flags non-BE VAT numbers for separate Intra-Community Listing (ICP) checks.
- Calculates net totals by automatically accounting for credit notes within the ledger.
Why use this skill
Manual preparation is prone to errors, especially with VAT number variations and threshold calculations. This skill ensures consistency by using a programmatic approach. It doesn't just filter data; it validates formats and signals anomalies—like domestic B2B sales missing a VAT number—allowing accountants to focus on review and filing via Intervat rather than data entry.
Output
The skill generates a structured CSV output and a summary report highlighting total reportable turnover, excluded private sales, and any international VAT numbers detected for further action.
