Procurement Anomalies
Shared Bank Account Detection
Finds distinct vendors that share an identical banking account, a classic collusion marker.
Why a shared bank account is a collusion alarm
When two ostensibly independent vendors are paid into the same bank account, the most innocent explanation is poor master data and the most serious is collusion, fronting or a shell network funnelling funds to one beneficiary. The AGSA and the SIU treat shared banking as a high-priority red flag in irregular-procurement investigations. AuditPro Core detects distinct vendors sharing identical account details so investigators can pursue the relationship before more payments flow.

Why distinct vendors should not share an account
Independent businesses bank independently. A shared account between vendors that bid against each other or transact with the same institution implies common control or a payment-diversion scheme.
Collusion and bid-rigging linkage
Shared banking frequently accompanies cover quoting and bid rigging, where related entities stage competition. The account link is the hard evidence connecting otherwise separate-looking bidders.
Payment-diversion and shell risk
A single account behind many vendor names can indicate shell companies created to multiply invoices or evade spend limits, with proceeds consolidated to one controller.
How AuditPro Core Bridges the Gap
- Account matching: identifies distinct vendor records sharing identical banking details across the master and payment file.
- Relationship linkage: cross-references shared accounts with shared directors and addresses to build a relationship picture.
- Exception workflow: escalates confirmed shared-account clusters for investigation and possible payment hold.
- Traceability to source: ties each match to the vendor records and payments involved for the evidence file.
Key Takeaways
- Independent vendors do not share a bank account; a match demands explanation.
- Shared banking is hard corroboration of collusion or bid rigging.
- One account behind many names points to shells and payment diversion.
- Combine the account link with shared directors and addresses for a complete case.
