As part of Crowe’s accounting services, we support clients in adapting financial and accounting processes to new requirements and in day‑to‑day handling of e‑invoices within KSeF.
Through the Crowe Platform, we provide an integrated invoice and accounting document workflow, including:

Such a solution enables companies not only to fulfil the new obligations related to e‑invoicing in Poland, but also to streamline control over document workflows and increase the efficiency of financial processes.

- branches
- representative offices
We support organisations reporting to foreign head offices, ensuring compliance with Polish accounting and tax regulations (VAT, CIT, JPK) while aligning reporting with Group requirements (e.g. IFRS).
We understand the specifics of the work of CFOs and controlling teams in an international environment; therefore, we provide:

Group reporting - data consistency and timely reporting
For companies with foreign capital, group reporting is a key element of cooperation with the head office. In addition to compliance with Polish regulations, data must be prepared in Group‑required formats, often under IFRS, and delivered according to strict month‑end schedules.
This involves:

- preparation of consolidation packages
- explanation of differences between local GAAP and IFRS
- timely delivery of financial data

Needs analysis
We start with a thorough analysis of your company and its accounting specifics. We identify detailed requirements related to financial settlements, reporting and tax obligations. Based on this, we prepare an offer tailored to your needs.

We prepare an agreement that clearly defines the scope of our accounting services, the cooperation schedule and reporting methods. Before signing the agreement, we conduct KYC and AML procedures. We ensure that the agreement complies with applicable regulations and reflects the specific needs of your company.

If your company is already operating, we begin by transferring data (as of the start date of cooperation) to our systems. We implement accounting procedures that ensure smooth service delivery, regulatory compliance and operational efficiency.

We deliver accounting reports tailored to your needs and providing the required level of detail. We also support the development of management reporting formats. Each client is assigned a dedicated accountant responsible for day‑to‑day cooperation.
Year-end services
Our support includes preparation of the financial statements, annual CIT calculation and preparation of the CIT‑8 tax return.

Online accounting - we work remotely, wherever you are

Regardless of your location (Poland or abroad), we ensure a structured and secure document workflow and continuous access to data required by controlling teams and the CFO, particularly during month‑end closing and reporting to the head office.
In practice, this means:

Why entrust your accounting services to us?
We are a stable partner
We have been operating on the market for over 35 years, supporting both Polish and international companies. Our team of experts has extensive expertise in full accounting, management accounting and financial reporting. Thanks to the scalability of our services, our clients can grow and develop together with us. Many companies cooperate with us long‑term (even for over 25 years).
We guarantee regulatory compliance
We guarantee that all accounting processes are carried out in accordance with current regulations in Poland. Where required, reporting meets international IFRS requirements. With our support, you gain peace of mind and security for your finances.
We ensure process security
We hold ISO 27001 and ISO 9001:2015 certifications, which confirm that we operate in line with the highest quality and security standards. Unlike smaller accounting firms, we help you effectively eliminate risks. Our professional liability insurance coverage amounts to PLN 10 million.
We use modern financial and accounting systems
We deliver our accounting services using both the IFS Cloud system implemented within our organisation and the accounting systems used by our clients to maintain books in compliance with Polish regulations, such as SAP, Exact, Microsoft Dynamics 365, NetSuite, SAP HANA, CDN XL and Navision.
The IFS Cloud ERP system, in addition to core financial and accounting functionalities tailored to client needs, provides:
- scalability adjusted to company size,
- availability in numerous language versions and support for companies operating in multiple countries,
- integration with external logistics, document processing and other applications,
- integration with banking systems and two‑way electronic data transfer,
- 24/7 secure remote access to data,
- comprehensive support in management reporting.
Process automation
We use automation in our accounting processes to eliminate human errors and reduce risk levels. This measurably improves quality and efficiency, allowing our clients to save time and reduce operating costs.
We prepare financial statements in accordance with IFRS and applicable regulations
Every company required to keep accounting books is also obligated to prepare financial statements reflecting its financial position and performance. For entities applying domestic regulations, the Accounting Act remains the basis for reporting, defining the scope, form and principles of financial statements. For capital groups and companies operating internationally, International Financial Reporting Standards (IFRS) are increasingly applied, shaping the recognition and presentation of financial data.
Differences between local standards and IFRS include, among others:
- presentation of data in financial statements,
- scope and level of disclosure,
- recognition and measurement of lease contracts (IFRS 16 vs local approach),
- recognition and measurement of revenue from sales,
- calculation of impairment allowances for trade receivables,
- analysis of impairment indicators for assets,
- asset valuation principles,
- provisions and contingent liabilities.
Accounting outsourcing facilitates IFRS implementation, particularly in group structures, by ensuring:
- consistent reporting processes,
- unified consolidation principles,
- ongoing substantive support.
As a result, financial statements are prepared in accordance with appropriate standards and meet both legal requirements and the expectations of owners and stakeholders.
Full accounting in Poland - who is it mandatory for?
Full accounting is the most advanced system of accounting records, requiring detailed recording of all a company’s financial transactions. It is a method used primarily by larger entities and those subject to specific legal requirements.
The obligation to maintain full accounting in Poland applies to the following entities:
Commercial law companies - regardless of revenue level:
- limited liability companies (sp. z o.o.),
- joint‑stock companies (S.A.),
- limited joint‑stock partnerships.
Entities with annual revenues exceeding EUR 2.5 million
Full accounting is also mandatory for sole traders and civil law, general and professional partnerships if their net revenues for the previous financial year exceeded EUR 2.5 million, converted into PLN according to the average exchange rate of the National Bank of Poland as at 1 January of a given year.Branches and representative offices of foreign companies in Poland
Full accounting is mandatory for branches and representative offices of foreign companies operating in Poland, regardless of their revenue level, in order to ensure compliance with Polish tax and accounting regulations.
Non‑governmental organisations (NGOs) and foundations
Full accounting is required for foundations and associations conducting business activities or receiving specific grants or public funds.
Other entities
In certain cases, the law imposes the obligation to maintain full accounting on other enterprises, such as those receiving subsidies or grants from the state budget to perform commissioned tasks.
If you are not required to maintain full accounting, you may still choose to apply it voluntarily. This can be justified, for example, if you have a complex cost structure, participate in tenders, or cooperate with larger companies that require detailed financial statements.
Not sure whether your company is required to maintain full accounting, or need professional accounting support?
Financial audits and tax inspections - obligations and expert support
Companies operating in Poland may be subject to financial audits and tax inspections aimed at verifying the correctness of accounting records and tax settlements. Financial audits focus on assessing compliance with the Accounting Act and, in the case of international groups, with group reporting requirements. Tax inspections verify the correctness of tax settlements (including VAT and CIT) and the completeness of documentation. Both processes require consistent financial data, orderly records and reliable documentation.
Accounting outsourcing at Crowe supports companies in preparing for audits and inspections - from ongoing bookkeeping organisation, through preparation of statements and reconciliations, to direct support in contacts with auditors and tax authorities. As a result, CFOs and chief accountants gain greater control over risk, smoother audit and inspection processes, and assurance of compliance with both accounting and tax regulations.
Accounting outsourcing - frequently asked questions
1. What is accounting outsourcing?
Accounting outsourcing involves entrusting accounting services to an external provider. This allows companies to avoid maintaining an in‑house accounting department and continuously tracking regulatory changes. It also ensures continuity of accounting processes without concerns about employee absences or staff turnover.
Additionally, external accounting service providers offer access to experts with extensive knowledge and experience across various industries, allowing services to be better tailored to specific business needs. Importantly, responsibility for the correctness of tax and accounting settlements rests with the external provider, providing additional assurance and reducing the risk of errors or regulatory breaches.
Accounting outsourcing can take various forms:
- full outsourcing - comprehensive accounting services, including bookkeeping, tax settlements, preparation of financial reports and other finance‑related tasks.
- partial outsourcing - outsourcing selected accounting activities, such as VAT settlements, preparation of tax returns, monthly management or group reports, ledger reviews, or preparation of annual financial statements.
2. How much do accounting services cost?
The cost of accounting services depends on several factors, including service scope, legal form of the company, number of documents, and additional requirements (e.g. reporting).

3. What are the benefits of accounting outsourcing?
Accounting outsourcing provides convenience and assurance that all financial and tax processes are conducted in compliance with applicable regulations. It helps avoid accounting errors and the consequences of incorrect settlements. Outsourcing also enables accurate budget planning by eliminating unexpected costs related to maintaining an in‑house accounting department. Cooperation with experienced experts provides access to up‑to‑date accounting and tax knowledge, enabling financial optimisation and adaptation to changing regulations.
4. Can I outsource only part of the accounting services?
Yes. Outsourcing may cover either full accounting services or selected processes, such as supervision and support of an internal team, tax settlements or financial reporting.
See partial accounting outsourcing.
5. Which companies most frequently use accounting outsourcing?
Most often, these are small and medium‑sized companies, start‑ups and foreign entities operating in Poland that find Polish regulations complex. Large companies also use outsourcing to focus on their core business areas.
6. Is an accounting firm liable for accounting errors?
Professional accounting firms are required to hold professional liability insurance (PI), which protects clients against potential accounting errors. This insurance covers costs related to correcting settlement errors, including late‑payment interest. Although tax liability ultimately lies with the entrepreneur, PI insurance provides additional protection and support.
7. What does accounting firm liability insurance cover?
- costs related to accounting errors,
- interest on overdue tax payments,
- liability for VAT and CIT settlement errors,
- costs of correcting errors (e.g. amended tax returns),
- protection against client claims resulting from accounting mistakes.
8. What documents must be provided to an accounting firm?
Depending on service scope, these may include:
- sales and purchase invoices,
- bank statements,
- payroll lists,
- employee business expense settlements,
- other documents required to be recorded in accounting books.
9. What does cooperation with an accounting firm look like?
Cooperation typically takes place remotely, with regular meetings to discuss needs and plans. Documents are submitted online. The accounting firm handles bookkeeping, tax settlements and communication with authorities. Our team works directly with group‑level finance contacts, such as foreign headquarters.
10. How to choose a good accounting firm?
Price should not be the sole criterion. Firms offering significantly below‑market rates may lack adequate staffing or technological resources, increasing the risk of errors and delays. Low PI insurance coverage or insufficient regulatory knowledge may expose your company to serious risks.
When selecting an accounting partner, consider:
- experience and client references,
- service scope,
- security or quality certifications (e.g. ISO),
- PI insurance coverage,
- modern solutions (e.g. online systems),
- pricing transparency and cooperation flexibility,
- availability of English‑language communication, if important for your organisation.
Accounting outsourcing
Comparison: Accounting outsourcing vs. in-house accounting department
Choosing between accounting outsourcing and maintaining an in‑house accounting department is a key decision for any company. Outsourcing offers flexibility, access to experts and modern solutions, while in‑house arrangements may be suitable for companies that prefer day‑to‑day cooperation with an on‑site team and want their finances to be closely integrated with daily operational processes. Below, we present the key differences between these solutions to help you make a decision tailored to your company’s needs.
