No reconciliation platform can make a finance team “SOC 2 compliant.” That’s a common shorthand, but it describes the wrong thing changing hands. SOC 2 is an attestation about a service organization’s own controls, evaluated by an independent auditor over an observation period, not a certificate a piece of software hands to whoever uses it. What reconciliation software actually contributes is narrower and more useful: the reconciliation logs, approval history, access records, and resolution notes an auditor needs to test a company’s own controls. That’s evidence support, not a compliance guarantee, and the distinction matters more than it sounds.
SOC 1, SOC 2, and why reconciliation touches both
Reconciliation sits in an odd spot because it’s relevant to two different SOC report types, and conflating them causes real confusion during vendor reviews. Deloitte’s overview of third-party assurance draws the line clearly: SOC 1 examines controls relevant to a service organization’s impact on a user entity’s financial reporting, covering things like ledgers, settlement, and payments, while SOC 2 examines controls against the Trust Services Categories, security, availability, confidentiality, processing integrity, and privacy. A reconciliation platform’s audit trail can support both conversations at once, since it documents financial accuracy for a SOC 1-style review and access and change control for a SOC 2-style one, but a single mention of “the logs” doesn’t automatically satisfy either audit on its own.
What SOC 2 auditors are actually testing
The AICPA’s Trust Services Criteria define the standard a SOC 2 examination is measured against. A Type 2 report, the version enterprise buyers actually ask for, evaluates whether controls operated effectively across an extended period rather than just being designed correctly on a single date. That distinction is why point-in-time screenshots don’t hold up as evidence. An auditor testing a Type 2 report wants to see the same control working consistently across the full window, not once.
This is also where sampling comes in. According to a 2026 press release from ISACA, the organization’s updated audit sampling guidance is meant to help IT audit professionals design and evaluate samples that produce sufficient, appropriate evidence, reflecting a shift toward more data-driven, technology-enabled sampling approaches. In practice, that means an auditor doesn’t review every reconciliation action taken over the audit period. They pull a sample and expect each item in it to be fully traceable, which only works if the underlying system logged every action the same way, every time, without gaps in the sample window.
Mapping reconciliation evidence to what SOC 2 actually asks for
The four evidence types reconciliation software produces map fairly cleanly onto specific Trust Services Categories, even though the mapping rarely gets spelled out.
| Reconciliation evidence | Trust Services Category it supports | What the auditor is checking |
|---|---|---|
| Access controls (who can view, edit, or approve records) | Security, Confidentiality | Whether access is provisioned, reviewed, and revoked appropriately |
| Approval history (maker-checker sign-off) | Security | Whether segregation of duties is enforced and documented |
| Reconciliation logs (matches, overrides, rule changes) | Processing Integrity | Whether the system processes and records transactions accurately and completely |
| Resolution notes (exception investigation and closure) | Processing Integrity, Security | Whether discrepancies are identified, investigated, and resolved through a controlled process |
Audit trails in financial reconciliation software cover the general structure behind all four rows, actor, action, before and after state, timestamp, and approval, but the table above is what turns that general structure into evidence an auditor recognizes against a named criterion rather than just a well-organized log.
Reconciliation logs and approval history: the processing integrity backbone
Processing integrity is the category most directly tested by reconciliation-specific evidence, since it asks whether a system’s outputs are complete, accurate, and authorized. Transaction matching audit logs are the clearest example: they show not just that a transaction matched, but under which rule, and whether a human intervened. Combined with approval history, the maker-checker record showing who reviewed and signed off on an adjustment, this is what lets an auditor trace a single sampled transaction from raw input to final disposition without a gap.
Rexi generates both of these automatically as part of running the reconciliation, not as a retrofit for audit season. That matters for Type 2 testing specifically, since evidence assembled right before an audit tends to look different in structure from evidence generated continuously, and auditors are trained to notice the difference.
Access controls and resolution notes: where security meets accountability
Access control evidence answers a narrower but equally important question: who was even capable of taking the actions the logs describe. Multi-provider payment reconciliation makes this harder to manage cleanly, since a platform pulling data from several sources often has to define different access levels for different integrations, not just different users. A SOC 2 auditor testing access controls wants to see provisioning, periodic review, and revocation all documented, not just a list of current permissions.
Resolution notes serve a related but distinct purpose. Exception audit trails in reconciliation capture the reasoning behind how a discrepancy was closed, and that reasoning is what an auditor actually reads when a sampled transaction turns out to be an exception rather than a clean match. A resolution note that only says “fixed” tells an auditor nothing about whether the process was followed. One that documents the root cause, the correction, and who approved it is what makes the sample pass.
Why “the vendor is SOC 2 certified” isn’t the same claim
A reconciliation platform holding its own SOC 2 Type II certification says something true and useful about the vendor itself: that its infrastructure, access management, and change control were tested and found effective over an observation period. According to a Businesswire announcement from MediStreams, a healthcare revenue cycle management and payment automation company, its own Type II examination confirmed that its controls over security, availability, and processing integrity operated effectively across a full 12-month period, evidence about MediStreams as a service organization, not about any specific customer’s internal controls. The same logic applies to Rexi: its SOC 2 Type II certification is evidence about how Rexi itself operates, not something a client inherits for their own organization simply by using the platform.
What a client’s own auditor actually needs is different: evidence, generated by the platform, that supports the client’s own control assertions. A Globe Newswire release from GCheck frames this shift plainly, noting that a SOC 2 Type II report has moved from a differentiator to a baseline expectation in vendor risk reviews, which is exactly why the underlying logs need to be usable by someone other than the vendor that produced them.
Why this evidence matters more as reconciliation moves to third-party platforms
The pressure on this evidence chain is increasing, not staying flat. In an open letter covered by PYMNTS, JPMorgan Chase’s Chief Information Security Officer warned that financial institutions’ growing reliance on third-party SaaS providers creates risk that ripples through the entire chain when a single vendor’s controls fall short. Finance teams evaluating a reconciliation platform are increasingly expected to justify that choice with more than a sales conversation, and the evidence the platform generates day to day is what actually answers that scrutiny.
Payment reconciliation audit trails exist for exactly this reason: to make sure the evidence a SOC 2 auditor eventually samples was captured the moment the transaction happened, not reconstructed under deadline. Rexi’s guide to payment reconciliation software applies that same principle across the whole workflow, not just the audit-facing parts. In the end, Rexi’s own SOC 2 Type II certification and its audit trail are two related but separate assurances, one about how Rexi operates, the other about what Rexi hands a client’s auditor when they come asking.
Frequently Asked Questions
Can payment reconciliation software make a company SOC 2 compliant?
No. Payment reconciliation software cannot make a finance team SOC 2 compliant by itself. SOC 2 is an attestation of a service organization’s controls over a review period. Reconciliation software can support the audit by producing evidence such as reconciliation logs, approval history, access records, and resolution notes, but the company still needs its own controls to be designed, operated, and tested.
What SOC 2 evidence does payment reconciliation software provide?
Payment reconciliation software typically provides evidence around transaction matching, approvals, access control, exception resolution, and change history. These records help an auditor see who took an action, what changed, when it happened, which rule or workflow applied, and whether the action was reviewed. That evidence is most useful when it is complete, attributable, and preserved over time.
How do reconciliation logs support SOC 2 processing integrity?
Reconciliation logs support processing integrity by showing how transactions were matched, whether the match followed an approved rule, and whether a human override was used. They help demonstrate that financial outputs are complete, accurate, timely, and authorized. A log that only shows a final matched status is weaker than one that records the rule, tolerance, reviewer, and approval path behind the result.
Why are approval history and segregation of duties important for SOC 2?
Approval history and segregation of duties show that sensitive reconciliation actions were not performed and approved by the same person without review. A maker-checker workflow creates evidence that overrides, adjustments, and exception closures were reviewed by someone with the right authority. That matters because SOC 2 auditors test not only whether a control exists, but whether it operated consistently during the review period.
Is a vendor’s SOC 2 Type II report enough for a customer’s audit?
A vendor’s SOC 2 Type II report is useful, but it is not the same as audit evidence for the customer’s own reconciliation process. The vendor report speaks to the vendor’s infrastructure, access management, and control environment. The customer still needs evidence showing how its own users configured rules, approved exceptions, managed access, and resolved reconciliation issues inside the platform.
Why does SOC 2 evidence matter more when reconciliation moves to third-party platforms?
When reconciliation moves into a third-party platform, more of the control evidence sits outside spreadsheets and internal systems. Finance teams need clear records that connect platform activity to their own control obligations: user access, approvals, rule changes, exception handling, and audit exports. Without that evidence chain, vendor assurance and internal control evidence can become confused during audits and customer security reviews.
