What is a Contra Transaction?
A contra transaction is an accounting adjustment used to offset the financial effect of an existing transaction without deleting or altering the original record.
In Mobiloan, contra transactions are primarily used after a transaction has been reconciled through the day-end cashbox reconciliation process and can no longer be edited or deleted.
Why does Mobiloan use contra transactions?
Once a transaction has been reconciled, it becomes part of an official accounting record. Editing or deleting it would compromise:
Audit trails
Financial integrity
Day-end reconciliation accuracy
Contra transactions allow users to correct balances while preserving the full transaction history.
When can a transaction be edited or deleted?
Before reconciliation:
Manual transactions are considered to be in a volatile state
Amounts can be adjusted
Transactions can be deleted if entered incorrectly
This flexibility exists because the transaction has not yet been locked into a day-end reconciliation.
What changes once a transaction is reconciled?
After day-end cashbox reconciliation:
The transaction becomes locked
Editing or deleting is no longer permitted
The transaction forms part of the permanent audit record
This follows standard accounting principles, where reconciled transactions must remain unchanged to ensure traceability.
How do I correct a reconciled transaction?
If a reconciled transaction is incorrect, you have two options depending on the scenario:
Create a contra transaction
Posts an equal and opposite entry
Neutralises the original transaction’s impact
Keeps the audit trail intact
Create a new manual transaction
Used when a direct contra is not suitable
Offsets the total balance to reflect the correct cash position
Both methods ensure the cashbox balances correctly without altering historical data.
Why not just delete the transaction?
Deleting reconciled transactions would:
Break reconciliation integrity
Obscure what actually happened
Fail audit and compliance requirements
Contra transactions make corrections explicit, visible, and auditable.
What is the key principle behind contra transactions?
The core principle is accounting transparency:
What happened must remain visible — only the financial effect may be corrected.
