Built for ISOs, sub-ISOs and agent offices

ISO agent software built for the way independent sales organisations actually earn.

Independent sales organisations don't sell software, they build books — books of merchants that pay residuals for years. Generic CRMs don't model any of that. Closerr is ISO agent software designed around the real economics: per-merchant residual splits between super-ISO, sub-ISO and writing agent, automatic clawbacks when a merchant attrits, and a live book the whole hierarchy can see.

What you get out of the box

Super-ISOs, sub-ISOs, agent offices and writing agents across the UK payments industry use Closerr to replace the spreadsheets, residual reports and home-built commission tools they outgrew the moment they signed their tenth merchant.

Multi-level residual splits

Model super-ISO → sub-ISO → agent splits per merchant, per processor, per product. Every party sees only what they should see.

Live merchant book per agent

Every signed merchant on one screen — volume, MCC, processor, residual history, contract end date — scoped by hierarchy.

Automatic clawback engine

Lost merchants reverse the original commission against future payouts, with a per-rep audit trail nobody can argue with.

Statement analysis built in

Upload a statement, get an instant savings number to take into the next meeting. No second tool, no spreadsheet.

Agent payslips every month

One clean payslip per agent covering residuals, signing bonuses, expense reimbursement and any clawback — fully traceable to source deals.

Hierarchy, roles and white-label posture

Owner, manager and rep roles map cleanly to super-ISO, sub-ISO and writing-agent structures. UK-native by default.

Why this matters

An ISO is a different business model from a SaaS sales team. The merchant signs once; the agent earns for years. The super-ISO, the sub-ISO and the writing agent each take a slice of the same residual stream. When a merchant attrits, the slices have to unwind cleanly. None of that is what a generic CRM was built for, and none of it is what a residual spreadsheet survives at any scale. Closerr is ISO agent software built specifically for this — the book, the splits, the clawbacks, the payslips and the audit trail — so the office can grow past a handful of agents without breaking the model.

Frequently asked questions

What is ISO agent software?

ISO agent software is a platform built for independent sales organisations in the payments industry. It covers the merchant book, residual income, multi-level commission splits between super-ISO, sub-ISO and writing agent, automatic clawbacks on attrited merchants and agent payslips — workflows generic CRMs do not model natively.

Does Closerr support sub-ISO and super-ISO structures?

Yes. The role and hierarchy model handles super-ISO → sub-ISO → writing-agent structures, with per-level residual splits, scoped visibility into the merchant book and a clean monthly payslip per party.

How are residual clawbacks handled?

Every clawback rule is configured at the plan level — windows, percentages, conditions. When a merchant attrits inside the window, the original residual is automatically reversed against future payouts with a full audit trail visible to both the agent and the office.

Is Closerr suitable for a UK ISO programme?

Yes. Closerr is built UK-native — sterling, UK postcodes, UK MCCs, UK acquirer context — and supports the hierarchy and split structures used in UK ISO programmes out of the box.
