Match CAM with lease evidence
Standard three way match does not fit annual CAM.
Oracle defines its match around three records. They are the bill, order, and receipt.
A landlord CAM statement has another structure. The lease sets the billing rules.
Planned CAM payments show what the client paid. The annual statement reports actual costs.
Landlord support explains those costs. These records need a lease aware match.
Know why the match fails
A purchase order states what the buyer wants. A receipt shows what arrived.
The vendor bill asks for payment. Standard matching compares those three records.
Washington State Auditor guidance uses that same basic model. Its rules apply to public agencies.
The control idea is still useful. The evidence must fit the transaction.
CAM is annual lease math. There may be no goods receipt.
There may also be no purchase order. A forced PO match can still miss lease errors.
Use three CAM evidence legs
Build the CAM match around three evidence legs.
| Evidence leg | Main records | Main question |
|---|---|---|
| Lease rules | Lease and changes | What may the landlord charge? |
| Client payments | Estimates and ledger | What did the client already pay? |
| Annual actuals | Statement and support | What costs did the landlord report? |
The third leg includes source support. Do not accept the statement total alone.
Lease invoice guidance calls for lease checks. It also calls for support on landlord true ups.
That source gives practice guidance. The signed lease remains the main source.
Map the lease rules
Turn each lease rule into a review field.
Start with these fields:
- CAM definition
- Cost exclusions
- Share method
- Area or other base
- Management fee rule
- Gross up rule
- Cap rule
- Base year rule
- Tax treatment
- Insurance treatment
- Review rights
- Notice terms
Do not guess when a clause is unclear. Assign that clause to a reviewer.
Counsel should review disputed legal meaning. The AP team should not make that call.
Match planned CAM payments
Create a payment schedule by lease year.
Use the client ledger as the source. Keep landlord planned bills as another record.
| Field | Purpose |
|---|---|
| Payment date | Shows when money left |
| Payment amount | Shows the amount paid |
| Lease year | Links payment to the statement |
| Property | Prevents site mixing |
| Payee | Confirms the landlord entity |
| Invoice reference | Links the source bill |
| Ledger link | Preserves client evidence |
Do not net unknown credits into the total. Route an unknown credit as an exception.
The payment sum answers one question. It does not prove the statement costs.
Test annual actuals
Break the statement into testable rows.
For each row, save these fields:
- Cost name
- Reported amount
- Support link
- Lease rule link
- Allocation base
- Client share
- Deterministic result
- Difference
- Review state
- Review owner
"Fixed math" means the same inputs give one answer. It does not mean the clause explains itself.
The reviewer decides which rule applies. Then the system can run the chosen math.
Use clear exception types
Do not combine every mismatch under one label.
| Exception | Meaning | Owner |
|---|---|---|
| Missing lease | The rule source is absent | Client file owner |
| Missing payment | A ledger record is absent | AP owner |
| Missing support | A statement row lacks proof | CAM reviewer |
| Amount mismatch | Saved amounts do not agree | AP owner |
| Math mismatch | Fixed math differs | CAM reviewer |
| Clause question | Lease meaning is unclear | Senior reviewer |
| Legal question | Rights or meaning are disputed | Counsel |
| Payment decision | Client action is needed | Client approver |
Walk one CAM match
This match example is fictional. The lease, property, and amounts are made up.
Green Pine Retail leases one store. Its lease allows a stated CAM share.
The client paid $12,000 in planned CAM bills. The annual statement reports $14,500 due.
The landlord asks for a $2,500 true up. That subtraction is correct.
Yet one cost row lacks support. The lease also excludes one listed cost.
Record the match this way:
| Leg | Evidence | Result |
|---|---|---|
| Lease rules | Signed lease and change | Exclusion needs testing |
| Client payments | Ledger totals $12,000 | Payment total supported |
| Annual actuals | Statement totals $14,500 | One row lacks support |
| True up math | $14,500 less $12,000 | $2,500 stated difference |
| Review result | Open | Cost rows need review |
Correct subtraction does not close the review. The cost base may still be wrong.
The AP owner confirms the $12,000 history. The CAM reviewer tests the cost rows.
The client approver controls payment action. Counsel reviews any disputed clause meaning.
Save one approval record
The final record should preserve each decision.
Save these items:
- Lease rule links
- Payment schedule link
- Statement and support links
- Recalculation record
- Open exceptions
- Reviewer decision
- Counsel note when needed
- Client payment decision
- Final output link
Do not replace evidence with a status word. "Matched" needs proof behind it.
Do not replace review with software output. A person must own the final decision.
Add the model to AP
Your AP tool can route the evidence. It can also track status and age.
Do not claim a native CAM connector. Use exports or linked records as needed.
Send the saved match record to the client approver.
The AP consultant pillar puts that record in the offer. The landlord invoice guide sorts issues before matching.
The CAM queue guide holds the match record. The utility control handles utility overlap.
The system consultant hub shows more system work. Use the Practice Growth hub to find another review owner.
Where CAMAudit fits
CAMAudit checks the three evidence legs in the record. It does not create the source records.
| Working record | Next owner |
|---|---|
| CAM match record | AP automation consultant |
It does not create receipt records. It does not approve payment.
CAMAudit reads the supplied lease and CAM records. It may run fixed math from chosen inputs.
It may flag a mismatch and cite source lines. It can place the checked work in a branded CAM audit.
Your firm reviews, then signs the checked CAM audit. Your team keeps final judgment.
The checked record may support a dispute letter draft.
CAMAudit may prepare that draft.
The draft is not legal advice.
Have counsel review before sending.
Carry the match record into the service line guide.
