# hsp GmbH has launched an app for estimating the cost of the e-balance sheet
With immediate effect, companies must submit their balance sheets to the tax office electronically. For many taxpayers, the additional costs involved are a „black box“: exactly how much will the extra work charged by the tax adviser for this project cost? What other uncertainties might companies face?

## An app that takes the work off your hands

To provide decision-makers with guidance and support in their decision-making, hsp GmbH has now launched an app on the App Store℠ and Google Play Store™ that carries out a comparative analysis: How much does it cost to have the e-balance sheet completed in full by a tax adviser, and how much does it cost if the groundwork is done using your own tool?

The E-Bilanz app uses a formula based on experts’ experience to calculate how much time the [Electronic balance sheet](../../en/e-balance-sheet/index.md) is expected to consume. This figure is compared with the estimated number of hours worked by a tax adviser. The respective time figures are then combined with a cost factor for man-hours. This makes it clear at a glance what potential savings an in-house software solution offers.

Specifically, the most labour-intensive part of preparing the e-balance sheet is the mapping process. This involves matching the relevant internal company accounts used for bookkeeping with the tax office’s prescribed taxonomy items.

## Long-term savings potential

Mapping accounts therefore offers significant long-term savings potential – something some companies fail to recognise – as many of these mappings are relatively straightforward to carry out. It is also likely that this mapping will be required for the preparation of every e-balance sheet due to changes in taxonomies.

With a certain level of tax expertise, a significant proportion of the mapping can be carried out in-house. This means the tax adviser needs to spend fewer hours on the task – and companies consequently save money.
