Systems Integrity
Why HOA Data Integrity Is a Fiduciary Issue
Data integrity sounds like an IT problem. For HOA boards, it is a fiduciary issue. Corrupted or unreliable financial data creates personal liability.
Data integrity sounds like something for the IT department to worry about. For HOA boards, it is a fiduciary issue.
When your financial data is unreliable, every decision you make based on that data is compromised. And you can be held personally responsible for decisions made on bad information if you should have known the data was unreliable.
What Data Integrity Actually Means
Data integrity is the assurance that data is:
- Accurate: It reflects what actually happened
- Complete: Nothing is missing
- Consistent: It does not contradict itself
- Unchangeable (where appropriate): Historical records are not altered
For HOA accounting, this means:
- The balance shown for each owner matches actual charges and payments
- The reserve fund balance is actually available for reserves
- The transaction history is the complete, unmodified record
- Reports generated today match reports generated last month for the same period
When Integrity Fails
Data integrity failures happen in predictable ways:
Manual Entry Errors A staff member types $2,350 instead of $3,250. The owner is undercharged. The operating fund is short. No one notices until the annual audit.
Import Failures A batch import from the bank fails partway through. Some transactions are recorded. Some are not. The books do not match the bank. Staff "fixes" it by adjusting balances.
Retroactive Changes Someone modifies a transaction from three months ago to "correct" an error. The change is not documented. Historical reports no longer match.
System Bugs The software has a bug that occasionally drops transactions during high-volume periods. Payments disappear. Owners dispute their balances.
Data Migration Moving from one system to another, historical data is converted. Some transactions convert incorrectly. Opening balances do not match closing balances from the old system.
Each of these creates data you cannot trust.

The Fiduciary Connection
As a board member, you have fiduciary duty. Courts have held that this includes:
- Exercising reasonable care
- Making informed decisions
- Implementing appropriate controls
If you know your financial data is unreliable and make decisions anyway, you may have breached your duty. If you should have known your data was unreliable (because controls were weak), you may have breached your duty.
Data integrity is not an IT problem. It is a governance problem.
Data integrity is not achieved by being careful. It is achieved by architectural choices that make corruption difficult or impossible.
Technique 1: Immutable Records
Once a transaction is recorded, it cannot be changed. To "correct" an error, you post a new transaction that reverses the original and another that records the correct values.
This means: - Original data is preserved - Corrections are visible - Historical reports never change - Audit trail is complete
Systems that allow direct edits cannot guarantee integrity.
Technique 2: Referential Integrity
Every transaction references valid entities: - Payments reference valid owners - Charges reference valid assessment schedules - Journal entries reference valid accounts
The database enforces these references. You cannot create a payment for an owner who does not exist. You cannot delete an owner who has outstanding balances.
Technique 3: Transactional Consistency
Complex operations happen atomically: - Either all parts complete, or none do - System crashes cannot leave partial state - Concurrent operations cannot conflict
If an assessment batch is processing 200 units and fails at unit 150, either all 200 are posted or none are.
Technique 4: Calculated Balances
Account balances are calculated from transactions, not stored directly: - Balance = sum of all debits - sum of all credits - Computed on demand or cached with verification - Cannot diverge from transaction history
Systems that store balances separately from transactions can have balances that do not match history.
Technique 5: Automated Reconciliation
The system continuously verifies internal consistency: - Do account balances match transaction sums? - Do inter-fund transfers balance? - Do bank imports match recorded transactions?
Discrepancies are flagged immediately, not discovered at month-end.
Signs Your Data May Be Compromised
Watch for these warning signs:
- Reports run on different dates show different values for the same period
- Staff talk about "adjustments" needed to make things balance
- Bank reconciliations require unexplained adjusting entries
- Owner balances do not match owner payment history
- Audit always finds variances that cannot be explained
- Historical data "was fixed" but no one can explain how
Any of these suggests your data may not be reliable.
What Boards Should Require
-
Immutable history: Corrections through reversing entries, not edits
-
Audit logging: Every change captured with who, when, what
-
Automated reconciliation: System detects discrepancies, not just staff
-
Data validation: System rejects invalid data, not just records it
-
Backup and recovery: Tested procedures for restoration
The Cost of Bad Data
Unreliable data creates real costs:
- Staff time investigating discrepancies
- Audit fees for extended testing
- Legal exposure from incorrect owner statements
- Board time dealing with disputes
- Reputation damage when errors become public
The investment in systems that ensure integrity pays for itself in problems avoided.
