The problem, first
Most projects start with one of these
Platforms like these get built to fix something that already hurts: a system that will not integrate, a process held together by spreadsheets, a channel that fails on the day it matters most. Here is how we approach four of the most common.
Your core system holds the data but cannot expose it. Every new channel becomes a change request to the core vendor, priced on their terms and scheduled against their roadmap rather than yours.
How we approach it. We place an integration layer in front of the core (an API gateway, event streaming, and documented contracts) so new channels can be built and released without touching it. The core stays where it is until replacing it becomes a business decision rather than an emergency.
End-of-day reconciliation runs on exported spreadsheets. Mobile money, cards, agents and the ledger are matched by hand, and one unexplained difference can hold up settlement for a working day.
How we approach it. We automate the matching and turn what is left into an exception queue with a named owner, a full audit trail, and a dashboard finance can rely on. Transaction monitoring and reporting run off the same pipeline, so the numbers are reconciled once rather than three times in three places.
The channel is comfortable for most of the month, then payday or month-end arrives and USSD sessions time out. Support absorbs the complaints, and the proposed fix is always another server.
How we approach it. We profile where the queue actually forms, decouple the channel from synchronous core calls using asynchronous messaging, and containerize it so capacity is provisioned against the peak rather than the average. Load testing runs against your real peak profile before the release, not after the incident.
A customer can begin onboarding on a phone but still has to visit a branch to finish it. Documents are re-keyed, drop-off is invisible, and the compliance file ends up in a folder somewhere.
How we approach it. We build digital onboarding and eKYC end to end (identity capture, verification integrations, risk checks and approval workflow), with every step logged in a form a regulator can follow. Identity and access management is designed in from the start, so one customer record serves every channel.
