Here are a few reasons:
1. One of your transactions has exceeded your per transaction high ticket limit, set by your processor. Typically, a signed invoice, a phone call with your customer, and financials or checking statements are required to get funding. Many ISOs auto approve without underwriting at $1000 high ticket. DonUp uses soft caps based on monthly volume.
3. Chargebacks have been received on the merchant account, and the processor is holding deposits until the amount of the chargeback is collected. Call your processor to figure this one out. DonUp works with clients regarding chargeback issues.
4. Merchant fees have rejected from the prior month. Must contact processor immediately to pay the fees to have the account reinstated.
