Need recommendations for using Timer in high volume transactions

Summary:

We have the following implementation in our system:
1) CPQ Submits Order payload to fusion via OIC asynchronously.
2) If due to any reason, OIC doesn't provide status update back to CPQ from Fusion within 2 hrs, run a timer on the transaction and move the status to "Order Failed in Integration"
3)The volume of the orders is close to 5000 orders / hr

Implementing this solution via timer is a recommended approach or not?
