Month end in any business is always a time to tally up the records and check everything was processed correctly. In a fleet business part of this should be to check that you have processed all of the administration fees that your fleet suppliers have passed to you.
Assuming that you receive your monthly invoice in electronic format and can easily copy data into an Excel file then Fleetworks make it very easy to ensure that you have processed (billed your client correctly) if you have been billed.
The process to check 1 fine or 1000 is identical and will take the same amount of time - approximately 2 minutes.
The first step would be to download the PCN template from your Imports screen. Once in Imports, select Create, pick PCN from the drop-down list and download the template. 
Once you have the template open, paste in the PCN reference numbers copied from your fleet supplier records. 
Save the file, go back to Imports and upload this file. After a few seconds Fleetworks will have processed the file and produced an upload report for you. 
You can instantly tell if a PCN has been imported and processed or not. In the above screenshot you can see that PCN references 5, 7, 11 and 12 are already loaded into the system. You can be comfortable that your normal systems will be processing and invoicing your clients.
However, the system did not identify the other PCN's as duplicate reference numbers so you should investigate further to ensure that your supplier has notified you correctly about the PCN. This would be especially important if it was a fine they paid on your behalf and were intending to bill you for.
The Chargebacks module has an identical feature. This way, if you are provided with new chargeback data but it is not always clear which chargebacks are new and need defending then you can import the chargeback case reference numbers and you will get an exception report back. Chargebacks not located need to be added and defended.
