Commercial Proof Of Funds And Bank Messaging For Counterparty Review
Financely supports companies that need proof of funds documentation, bank comfort support, soft probe coordination, or authenticated bank-to-bank messaging as part of a wider commercial transaction. These requests usually arise in commodity trades, acquisitions, project-related negotiations, supply contracts, and other transactions where a counterparty needs evidence of banking capacity before moving forward. To understand our broader transaction-led model, you can review what we do , or move directly to our deal submission page.
Not every transaction needs the same form of comfort. Some counterparties only need a documentary indication that banking support exists. Others want a bank comfort letter framed around an identifiable transaction. In some cases, a soft probe is requested before deeper engagement begins. In others, the process moves to authenticated bank-to-bank messaging such as MT199 or MT799. The commercial objective stays the same: create enough confidence for the transaction to proceed without overstating what the bank communication actually means.
That distinction matters. A proof of funds request, a bank comfort letter, a soft probe, an MT199, and an MT799 do not serve identical purposes. The right route depends on the stage of the transaction, the counterparties involved, the documentary expectations, and the degree of bank-to-bank confirmation required. Businesses wanting a clearer picture of our process can review how our engagement model works. Companies comparing bank messaging with wider financing options can also explore our AI-powered lender matching service where a broader capital process is also in view.
Proof Of Funds
Proof of funds is the broad category. It can include documentary evidence or bank-originated confirmation used to show that financial capacity exists for a defined commercial purpose.
Bank Comfort Letter
A bank comfort letter is generally used to provide transaction-linked banking comfort. It is not the same as a payment undertaking, but it can help counterparties assess whether the banking side is aligned with the proposed deal.
Soft Probe
A soft probe is typically used where one side wants discreet bank-level comfort or preliminary confirmation before moving into a more formal process. Its role depends on the transaction and the banks involved.
MT199 And MT799
MT199 and MT799 are authenticated bank-to-bank SWIFT message formats often used for commercial communication, pre-advice, or confirmation-related workflow. They are messaging tools, not funding instruments by themselves.
Where value is created: the right form of bank comfort can move a transaction forward, while the wrong form can slow negotiations, create avoidable questions, or misalign expectations between counterparties, banks, and advisors.
How The Main Formats Differ
| Format | Typical Commercial Use | What It Helps Address |
|---|---|---|
| Proof Of Funds | Used where a counterparty wants evidence of financial capacity for a defined transaction. | Initial comfort around whether funds or banking support exist at a level relevant to the deal. |
| Bank Comfort Letter | Used where the transaction calls for a bank-originated comfort document tailored to the commercial context. | Counterparty confidence, transaction momentum, and early stage documentary assurance. |
| Soft Probe | Used where preliminary bank-level inquiry or discreet comfort is preferred before a more formal step. | Early validation of whether a counterparty’s banking position supports continued negotiations. |
| MT199 | Used for authenticated bank-to-bank communication where free-format messaging is suitable. | Commercial coordination, status communication, or tailored bank messaging linked to the transaction. |
| MT799 | Used for authenticated bank-to-bank communication where a stronger pre-advice or readiness message is being requested. | Cross-bank communication before a later instrument or funding step, subject to the specific bank workflow. |
What We Review Before A Request Moves Forward
The starting point is always the underlying transaction. We review the deal purpose, the amount, the counterparties, the jurisdictional context, the documentary need, and the timing of the request. A supplier asking for comfort before allocating goods is not in the same position as a seller requesting authenticated bank messaging before contract signing, and neither is in the same position as a project sponsor seeking transaction-linked proof of funds for a tender or acquisition process.
We also review the practical path. In some cases, a bank comfort letter is sufficient. In others, a soft probe is the cleaner first step. Where the counterparty requires authenticated bank-to-bank communication, MT199 or MT799 may be the more relevant route. The point is not to make the request sound more sophisticated than it is. The point is to choose the format that matches the commercial stage of the transaction and the expectations of the receiving side.
Transaction Fit
We assess the purpose of the request, the stage of the negotiation, and whether the chosen format fits the actual commercial objective.
Document Readiness
We review contracts, term sheets, transaction summaries, and related materials so the banking request is grounded in a real commercial file.
Counterparty Expectations
We help align the request with what the receiving side actually expects to see, which can reduce unnecessary back and forth later.
Execution Path
We help prepare the transaction so the selected bank comfort or messaging route fits the timing, workflow, and broader structure of the deal.
Important: proof of funds documentation and authenticated bank messaging should not be treated as substitutes for underwriting, contractual alignment, or final transaction approval. They are supporting tools within a wider commercial process.

Frequently Asked Questions
What is proof of funds in a commercial transaction?
Proof of funds is a broad term for documentary or bank-originated evidence used to show that financial capacity exists for a defined transaction or commercial purpose.
What is a bank comfort letter?
A bank comfort letter is a transaction-linked comfort document issued within a banking context to support counterparty confidence. It is not the same as a payment guarantee or direct undertaking to fund.
What is a soft probe?
A soft probe is typically used for preliminary or discreet bank-level inquiry before a transaction moves into a more formal confirmation or messaging stage.
What is the difference between MT199 and MT799?
Both are authenticated SWIFT bank-to-bank message types used for communication. In practice, the choice depends on the intended workflow, the bank process, and what the counterparties are trying to confirm at that stage.
Does an MT199 or MT799 guarantee funding?
No. MT199 and MT799 are message formats used within a banking communication process. They do not by themselves create a funding commitment or replace the broader transaction review.
Can Financely issue the bank message directly?
No. Financely is not a bank. We provide advisory support on transaction fit, document readiness, and structure so the appropriate request can be prepared and routed through the relevant banking or execution path.
