When a company opens a business account, receives larger payments or prepares an international transfer, banks and electronic money institutions often need to understand where the funds come from.
This is not only a question of bank statements. Institutions usually review the ownership structure, business model, expected payment profile and the documents that explain the economic origin of funds.
Quick answer
A proof of source of funds explains where specific funds come from and why they are plausible for the company. Depending on the case, relevant documents may include bank statements, invoices, contracts, financial statements, tax documents, shareholder resolutions, loan agreements, purchase agreements and UBO information.
Why institutions review source of funds
Financial institutions have to understand their customers and assess whether the expected account activity is consistent with the company profile. For companies, this means that formal corporate documents are only one part of the review.
The institution also needs to understand who controls the company, how the business generates revenue, which countries and currencies are involved and whether larger incoming or outgoing payments match the declared activity.
Source of funds and source of wealth
Source of funds describes the origin of specific money used for an account opening, transfer or payment. This may include business revenue, shareholder loans, capital contributions, asset sales or retained earnings.
Source of wealth describes how a person or structure built overall wealth. It can become relevant when a shareholder introduces significant capital or when the wider economic background of funds needs to be explained.
| Term | Meaning | Typical examples |
|---|---|---|
| Source of funds | Origin of specific money | Revenue, loan, capital contribution, sale proceeds |
| Source of wealth | How overall wealth was built | Business activity, investment exit, property sale, inheritance |
| Payment profile | Expected use of the account | Countries, currencies, counterparties, SEPA, SWIFT, monthly volume |
Situations with increased review effort
Source-of-funds questions are especially common for international companies, young companies without a long account history, high-value payments, shareholder loans, capital contributions, property transactions and complex ownership structures.
The review is not automatically negative. It simply means that the institution needs a clear explanation and documents that fit together.
Which documents companies should prepare
The exact documents depend on the institution and the case. Companies should usually prepare current corporate documents, ownership information, business model evidence, payment profile and documents explaining the origin of specific funds.
| Area | Typical documents | Purpose |
|---|---|---|
| Company | Register extract, incorporation document, articles, shareholder list | Legal existence and structure |
| UBO | Ownership chart, IDs, shareholding percentages, holding documents | Beneficial ownership transparency |
| Business activity | Website, contracts, invoices, service description | Commercial plausibility |
| Source of funds | Bank statements, invoices, payment evidence, loan agreements | Origin of specific funds |
| Payment profile | Countries, currencies, volumes, counterparties, SEPA or SWIFT needs | Expected account activity |
UBO structure and ownership chain
The source-of-funds review is closely connected to the beneficial ownership structure. Institutions usually need to trace the ownership chain to the natural persons behind the company.
For simple structures, a shareholder list may be sufficient. For multi-layer holdings or international structures, an ownership chart helps explain each entity, jurisdiction and percentage.
Payment profile: countries, currencies and volumes
A payment profile explains how the account will be used. It should describe expected incoming payments, outgoing payments, countries, currencies, counterparties, monthly volume and whether SEPA, SWIFT or multi-currency functions are needed.
The profile should be realistic. Very low estimates can cause problems if much larger payments arrive later, while high estimates without supporting evidence may raise additional questions.
Common mistakes
- Submitting bank statements without explaining the economic background
- Missing link between invoices, contracts and incoming payments
- Unclear UBO chain in holding or international structures
- Application details that do not match the website or documents
- High expected volumes without contracts or customer evidence
- Mixing up source of funds and source of wealth
- Using outdated or expired corporate documents
How companies can prepare
Preparation should start with the specific reason for the review: account opening, larger incoming payment, capital contribution, overseas payment or compliance request. The next step is to assign the relevant funds to clear sources and collect supporting documents for each source.
Before submission, the company should check whether application form, website, corporate documents, UBO information, invoices, contracts and payment profile tell one consistent story.

Conclusion
Proof of source of funds is more than a single bank statement. Institutions need to understand whether funds, ownership structure, business model and expected account use fit together.

Frequently asked questions
Is a bank statement enough as proof of source of funds?
Sometimes, but often not. A bank statement shows that funds exist. It may not explain the commercial or economic origin of those funds.
When is source of wealth relevant?
Source of wealth can become relevant when significant capital is introduced by a shareholder or when the wider background of accumulated wealth needs to be explained.
Which documents matter for larger payments?
Contracts, invoices, bank statements, payment evidence, shareholder resolutions, loan agreements or purchase agreements may be relevant depending on the case.
Why do institutions ask for a payment profile?
The payment profile helps the institution assess whether expected countries, currencies, volumes and counterparties are consistent with the business model.
