Which parts of accounting should you outsource?

Which parts of accounting should you outsource? - Leinonen Group

For many companies expanding internationally, one of the first finance decisions appears straightforward: should accounting be handled internally or outsourced? In practice, this is rarely a binary decision. The answer affects more than just the accounting costs. It influences compliance risk, management visibility, scalability and how much internal management attention is consumed by finance administration.

There are at least three viable operating models

Companies typically operate somewhere along a spectrum rather than choosing simply between “internal” and “outsourced” finance.

1. Client-owned finance

At one end are companies with established finance departments, systems and processes.

They may already operate SAP, Microsoft Dynamics 365, Business Central, Oracle, Workday, Odoo or another group-wide platform. Their internal finance organization owns the process, while external specialists provide local accounting and compliance expertise.

The advantage is control.

The company retains its ERP, approval structures, reporting logic and group processes. A local accounting provider works within this environment rather than replacing it.

This approach can be particularly suitable for organizations where finance is already standardized internationally and local operations need to fit into a global model.

But there is a trade-off: local compliance has to work within a system that may not have been designed around local requirements. That makes integration and clearly defined responsibilities particularly important. That also means a hefty budget should be allocated for localization.

2. Provider-led finance

At the other end of the spectrum, a company may decide that building its own local finance infrastructure makes little economic or operational sense. Instead of recruiting a finance team, selecting accounting software and designing workflows locally, the business delegates most of the finance operation to its accounting provider.

In this model, the provider manages the accounting setup, including systems, processes, accounting logic and compliance, allowing management to concentrate on the operating business.

For a newly established subsidiary, for example, management may prefer to focus resources on customers, employees and market development rather than recreating a finance infrastructure that already exists elsewhere.

However, outsourcing the function does not mean outsourcing management responsibility. Management still needs visibility, appropriate controls and reliable financial information. The challenge is therefore not simply transferring accounting work to somebody else. It is designing an operating model where responsibility, data and decisions continue to flow properly.

3. Hybrid finance

For many businesses, the answer is somewhere between these two models.

A company might:

  • issue invoices through its own ERP;
  • retain its internal approval process;
  • use a local provider for statutory accounting;
  • outsource payments management;
  • outsource local tax compliance;
  • receive standardized management reporting from a service provider locally.

This hybrid model can be particularly effective when headquarters wants to maintain control over business-critical processes while avoiding the complexity of maintaining every element of local finance internally.

Start with the business process, not the accounting system

One common mistake is to treat accounting as something that happens after the business activity has already occurred. In reality, accounting depends on processes taking place much earlier.

Consider a supplier invoice. Before that invoice appears in the general ledger, somebody has already received it, identified what it relates to, approved the cost, determined where the expense belongs, authorized payment and supplied the necessary supporting information.

Only then can accounting properly process the transaction. The same logic applies to sales invoices, employee expenses, payroll information and bank transactions. Finance should therefore be approached as a sequence of input, processing and validation, and financial output, rather than by looking only at bookkeeping itself.

This distinction matters because many “accounting problems” are actually process problems originating before accounting begins. If supporting documents arrive late, approvals happen outside the established workflow or transaction information is incomplete, adding more accountants does not necessarily solve the underlying issue.

The right model depends on what you want to control

There is no universally superior structure.

A multinational with a sophisticated internal finance function may reasonably want its external accountants to work inside the group’s environment. A smaller international subsidiary may reach the opposite conclusion: maintaining its own local accounting infrastructure adds cost and complexity without providing strategic advantage.

Decision makers should therefore consider several questions:

Where should process ownership sit?

Which financial processes are strategically important enough to remain under direct company control?

Where should the systems sit?

Does the business need accounting to operate inside the corporate ERP, or is reliable integration with the group environment sufficient?

Who carries local knowledge?

Tax, accounting and reporting requirements remain jurisdiction-specific even when finance operations are internationally standardized.

How much local infrastructure is economically justified?

The answer for a 15-person subsidiary may be very different from the answer for a 500-person organization.

What happens if the organization grows?

An operating model that works at market entry should not become an obstacle when transaction volumes, employees or reporting requirements increase.

The goal is not maximum outsourcing

Nor is it maximum internal control. The goal is to create a finance operating model where ownership follows business value.

Processes that genuinely differentiate the company or are central to management control may belong internally. Processes where local expertise, standardization and scale provide greater value may belong externally. Increasingly, successful finance organizations combine the two.

For decision makers, that is a much more useful starting point than simply asking: “Should we outsource our accounting?”

All of this is what a proper accounting partner will guide you through, help evaluate and most importantly be able to execute any of the models.
