A software matrix for merchant-services back offices
ISO Stack compares CRM, residual, boarding, and related software used by merchant-services operators.
- For
- ISO owners, agent offices, and PayFac ops managers
- Worth noticing
- The methodology leaves unknown matrix cells blank and rejects paid “Editor’s Choice” badges and invented ratings.
Field notes
The sample rows distinguish product roles rather than treating every listing as the same kind of CRM: SplitRun is described as importing processor residual files and producing agent statements, while ResidualsOS is framed around book close, reconciliation, splits, and publishing. Pricing is unevenly available: the page gives ranges or minimums for some entries and labels other figures as vendor-stated. Its linked methodology and blank-unknown rule make the limits of the comparison part of the product.
