Accounting in SAP Business One – What Can an External Accounting Firm Take On?

Könyvelés SAP Business One rendszerben - az MGI-BPO egyik szolgáltatása.

More and more mid-sized companies use SAP Business One (SAP B1) to support daily operations, inventory management, and sales. In such cases, a common question arises:
how can an external accounting firm integrate into this system, and where are the boundaries of responsibility between finance, SAP, and operations?

Below we present our approach and practical experience.

Do We Have Experience with Accounting in SAP Business One?

Yes. Several of our clients use their own SAP Business One systems, and we connect to these systems as external accountants with dedicated user access and authorization levels.

This allows us to:

  • work directly within the system,
  • review accounting data,
  • and ensure compliance with accounting standards.

Which SAP Business One Modules Do We Work With?

As we focus on general ledger accounting, we typically operate in the following setup:

  • Financial / General Ledger module – we have access to this
  • Inventory, purchasing, and sales modules – remain under the client’s control

This is a well-established and clear division of responsibilities:

  • the client records operational transactions,
  • we ensure that these are properly and consistently reflected in the general ledger from an accounting perspective.

Who Handles the Accounting: SAP Expert or Accountant?

Accounting is performed by qualified accountants who are familiar with SAP Business One.

It is important to emphasize:

  • technical and product-specific SAP configuration is typically the responsibility of an SAP consultant,
  • we get involved where accounting decisions, posting logic, or tax-related questions arise.

Ideally, the client has their own SAP consultant, and
we support them from an accounting perspective whenever financial or tax considerations are involved in system setup.

How Does Day-to-Day Accounting Work in SAP Business One?

In practice, the workflow is typically structured as follows:

  1. The client records daily transactions (invoices, bank entries, operational items)
  2. We:
    • review the entries,
    • post journal entries,
    • prepare tax returns,
    • and compile annual financial statements

This model is efficient, scalable, and creates clear responsibilities.

What Reports Can Be Generated Directly from SAP Business One?

The reporting capabilities of SAP Business One depend significantly on the client’s system setup. Therefore:

  • the type of reports,
  • level of detail,
  • and format

are always agreed in advance.

We tailor reporting to business needs rather than relying on “off-the-shelf” solutions.

Payroll and SAP Business One

Payroll is handled:

  • in a dedicated Hungarian payroll software (Babér),
  • and then integrated into SAP via posting entries.

Handling VAT, Corporate Tax, and Other Returns

The extent to which tax returns can be generated directly from SAP depends on:

  • which modules are implemented,
  • and how effectively they function in the system.

In all cases, we:

  • review the data,
  • and ensure that returns comply with Hungarian regulations—whether based on SAP data or supported by additional tools.

Professional Liability

We maintain professional liability insurance and take responsibility for the accounting work we perform.

This is particularly important in complex systems and international structures.

What We Consider Key in an SAP Business One Environment

Success depends on:

  • clearly defined roles,
  • strong collaboration between accountant, client, and SAP consultant,
  • and a well-structured accounting approach to system usage.

We do not “operate” SAP—we ensure that the data within the system meets accounting, tax, and reporting requirements.
