Selecting the Transaction
Highlight the transaction you wish to cancel and select:

If approved:
•the transaction will be reversed
•the payment will be removed from the workorder totals
•accounting records will update automatically
Important Difference Between a Void and a Credit
A:
•VOID
normally cancels a transaction before it fully settles through the merchant processor.
A:
•CREDIT
refunds money after settlement has already occurred.
Voids are generally:
•simpler
•faster
•less expensive
because the funds may never fully leave the customer’s account.
Time Limits on Voids
⚠️ Important:
Most merchant processors only allow voids within a limited time period.
This is commonly:
•the same business day
•before batch settlement
•before nightly processing closes
Once a transaction has settled:
•it usually can no longer be voided
•a credit/refund must be issued instead
The exact rules depend on:
•the merchant processor
•the card provider
•settlement timing
Automatic System Updates
When a void is successfully processed, MLS 2026 automatically updates:
•workorder balances
•merchant transaction records
•accounting activity
•payment totals
This helps maintain accurate financial reporting throughout the system.
Use Caution When Voiding Transactions
⚠️ Voiding transactions should be handled carefully.
Always verify:
•the correct transaction was selected
•the customer requested the cancellation
•the invoice status is accurate
Improper voids can create:
•customer confusion
•accounting discrepancies
•duplicate processing problems
Recommended Best Practices
Before issuing a void:
•Verify the original transaction carefully
•Confirm the invoice status
•Make sure the transaction has not already settled
•Document the reason for the void
•Limit void authority to trusted personnel
If a Void Is Rejected
A void request may fail because:
•the batch has already settled
•the transaction is too old
•the merchant processor rejected the request
If this happens:
👉 issue a standard credit/refund instead.
Best Practice Reminder
Voids are generally preferred over refunds when the transaction has not yet settled because:
•processing is cleaner
•accounting is simpler
•funds move faster
•merchant fees may be reduced
