In this article you will learn how to work around/fix VAT rounding issues.

Requirements

• RetailForce Client version 1.2.10 or higher

Symptom

When transmitting a document to the fiscal system (StoreDocument) or also during validation (ValidateDocument), the following validation error is issued by the system:

Error: NetValue + TaxValue does not equal GrossValue.

Solution

As of version 1.2.10, the RetailForce system supports a tolerance for rounding VAT amounts. This tolerance is set to 0 by default for compatibility reasons with older versions.

The VAT rounding tolerance can be controlled per document configured as follows:

• Set the Document.AllowedVatDeviation field to the desired tolerance value in EUR.

Example

A value of 0.05 allows a tolerance of +/-5 cent (if EUR is the base currency)
