01Overview

Merchant onboarding, settlement visibility and terminal health for an acquirer that ran all three on paper and phone calls.

02The problem

Signing a merchant took nine days and a courier. Every settlement question became a phone call because merchants could not see when money would land, and a dead terminal was only discovered when the shop complained.

The whole terminal fleet on one desk, eleven silent devices already raising field visits
03What we built
  1. 01

    Onboarding in an afternoon

    Trade licence, bank and ownership checks run against source registries during the application, so approval is same-day instead of next week.

  2. 02

    Show them the money

    A merchant app with a settlement timeline: what was captured, what is in transit, what lands tomorrow and why a deduction happened.

  3. 03

    Terminals that report themselves

    Device telemetry surfaces connectivity, battery and failed-transaction spikes, so a field visit is dispatched before the merchant notices.

A bakery approved the same afternoon it applied, every check answered by a registry
A merchant reading why tomorrow's figure is what it is, without ringing anyone
04The result

Onboarding is now a same-day process, settlement support quieted down, and terminal downtime is measured in hours rather than discovered in complaints.

Closing

Do you have an idea, or a problem?

Either works. In my experience the second one goes faster.

I usually reply the same day.
