When an Austrian business is acquired, the cash register is often treated as a technical detail. In practice it can become a key evidence point. The buyer needs to know which turnover belongs to the seller period and from which moment the buyer controls the records.

This is especially relevant in asset deals with daily cash sales. Cash reports, zero receipts, start receipts and access rights should not be left to an informal handover.

This post focuses on the transaction-specific review of the cash register and FinanzOnline access. It does not repeat general tax compliance rules.

Classify your cash register handover

Is the cash register ready for closing?

Answer two questions on the closing cut-off and access rights. You receive an initial contract-oriented assessment.

Already know you want to get in touch? Go straight to the enquiry form.

01 Question 1

Is it clear which cash register period belongs to the seller and when the buyer takes over?

In an asset deal the cash register needs a clean economic cut-off. Otherwise old turnover and new turnover are mixed.

All paths at a glance

Overview of all answers.

01

The cash register cut-off must be fixed first.

Without a clear cut-off it is hard to prove later which turnover and receipts belong to the seller period. Agree a cash register closing report at completion and list the reports, zero receipts and logs to be delivered.

The general review logic follows our due diligence checklist.

02

The cash register handover is well prepared.

If cut-off, receipt evidence and new access rights are regulated, the register can move into the buyer operation in a controlled way. Still include warranties on the proper records for the past period and an indemnity for identified old risks.

03

Individual documents are missing and should be added before signing.

If start receipt, zero receipt, closing report or access separation is missing, the buyer remains exposed in a later audit. Request the documents before signing or make their delivery a condition to closing.

Document the cash register cut-off at closing

A business acquisition usually has an economic effective date. For the cash register this means that the seller is responsible for records up to that point and the buyer must control the register afterwards. The cut-off belongs in the handover protocol and not only in a phone call on completion day.

Daily closing reports, monthly reports, zero receipts and open transactions should be allocated clearly. In cash-heavy businesses the register reports often show the real operating picture. Our focus page on the share deal or asset deal explains why this distinction is especially sharp in an asset deal.

Separate FinanzOnline and technical access rights

The buyer should not continue working with the seller access credentials. FinanzOnline, the cash register provider, tax adviser access and administration rights must be separated. What feels technically convenient can become legally unclear when old and new periods are mixed in a later audit.

The handover should state who keeps access, who removes it and which new permissions are created from closing. This is a closing action and not a mere IT side issue.

Warranties and indemnity for seller periods

The buyer can rarely verify the proper records for the entire past period. The purchase agreement should therefore contain warranties on cash register compliance, completeness of receipts and known audits. If specific findings exist, a targeted indemnity for old periods is advisable.

The contract logic is close to other tax and compliance risks. Our post on the warranty catalogue explains how warranties can be structured.

Checkpoints

Cash register, access rights and receipts before closing

This overview shows which special issues must not disappear in generic clauses.

Cash register in an Austrian business acquisition: typical points to check
Point Why it matters Contract consequence
Closing report Closing report Separates old turnover and new turnover. Closing document and handover protocol.
FinanzOnline FinanzOnline Seller access rights must not continue. New permissions and removal of old rights.
Receipts Start and zero receipt Evidence for technical order and later audit. Delivery as condition or warranty.

The Austrian Federal Fiscal Code and the cash register security rules form the tax framework. The handover must fit the actual system and business.

Practice note: Do not leave the cash register review until completion day. The evidence belongs in the data room and the access separation belongs in the purchase agreement.

Different from family succession

In a family succession, continuity and internal access rights are often the focus. In an external business acquisition, the buyer must prove what was acquired and when the buyer became responsible. That buyer perspective makes the issue separate.

This post therefore addresses the transaction-specific transfer of the register, access rights and evidence in an acquisition. It is not a general article on cash register duties.

FAQ

Cash register in an Austrian business acquisition.

Does the buyer have to take over the old cash register? +

No, the structure matters. A register may be used further if technical control, access rights and cut-off are regulated. Often a new own access or re-initialisation is safer.

Which documents matter for the register? +

Closing report, zero receipt, start receipt, monthly reports, technical logs and access rules are important. Depending on the business, the software contract and tax adviser access also matter.

Who bears old recording errors? +

The purchase agreement should regulate this expressly. Warranties on proper records and indemnities for tax risks from the seller period are common.
