How long do we have to investigate a business account dispute? We do provide provisional credit within 5 business days. Our business card agreement does not state how long it will take to complete the investigation.

Thanks

You have as much time as is needed to work through the V/MC chargeback and arbitration processes. The card brands set the timeframes for how long after a transaction you have to file a chargeback, how long the merchant has to represent, and how long each party has following representment to file preabitration/arbitration.

Thank You

Internally, working off the applicable chargeback timelines I believe it behooves a bank to procedurally set internal timelines so that nothing falls through the cracks. Like consumer accounts, these should be tracked for progress and have internal controls with deadlines for completion. Business accounts may simply be longer or allow more flexibility.
