Fraud & Chargeback Prevention
Chargeback prevention services that stop disputes before they are filed
Chargeback prevention services covering the controls that reduce disputes at the source: dispute alert networks, 3-D Secure, fraud rules, descriptor and refund policy hygiene, and customer communication fixes identified from your dispute data.
Built for every buyer we serve
Card-not-present merchants, subscription businesses, high-risk verticals, and ISOs protecting portfolio accounts.
Why this costs you money
These are the failure modes we see most often in Managed Payments Operations.
Most chargebacks are preventable, and the fixes are operational, not technical.
Card brand thresholds are measured monthly; a bad quarter can cost you the account.
Fraud tools are installed and never tuned.
Everything included, in writing
Scope is written down before work starts, and changed only in writing. Nothing is added or dropped without a written change order.

What makes this different
These are specific to Managed Payments Operations, and they are in the scope document rather than only on this page.
We work inside your systems
Your processors, gateways, CRM, and portals, under your brand. You keep every merchant account and relationship.
A named desk with a named lead
A specific team, defined coverage hours, and response-time commitments written into the scope document.
Measured on numbers you can audit
Win rates, attrition, residual variance, and open items, reported weekly and built from your records.
We never touch funds
Midcore holds, transmits, and settles nothing. Access is scoped to the work, logged, and revocable at any time.
What clients say
We publish no client names. These describe the shape of real engagements in Managed Payments Operations.
See the engagementsOur agents were spending half their week on paperwork. The desk took the boarding queue, the disputes, and the residual reconciliation. Same headcount on the sales side, materially more selling.
They found variances in our residual statements that had been running for years. What mattered more was the monthly reconciliation they left behind, so it does not happen again.
We had been quoted eighteen months and seven figures to register as a PayFac. Midcore mapped the alternative in two weeks and told us plainly that our volume did not justify it yet. That conversation saved us a year.

What the work looks like
Anonymised engagements from Fraud & Chargeback Prevention and the wider Managed Payments Operations practice.
All case studiesA rising dispute ratio put the account within sight of a card brand monitoring program, and with it the processing relationship itself.
Subscription merchant processing at scale An ISO gave its agents their selling week backAgents were spending roughly half their time on statement analysis, applications, and chasing processors. The fix was not more headcount on the sales side.
Independent sales organization A sub-ISO found years of residual variance in one auditResidual statements had been accepted as correct since the business started, because nobody had the time or the method to check them line by line.
