+Base VAT Sanitized
+==================
+
+This module adds a technical field *sanitized_vat* on partners that stores the VAT number without spaces and with letters in uppercase. It is useful for other modules that need to match partners on VAT number, such as the *account_invoice_import* module for example.
+
+Configuration
+=============
+
+No configuration is needed.
+
+Usage
+=====
+
+This module doesn't bring any visible feature for the users.
