MLMY is an engineering-led consultancy that develops, tests, and tunes the business support systems behind telecom operators and service providers — convergent billing & charging, CRM, order management, mediation, and the integrations that tie them together.
We work across the full business support stack — from a single component to a full transformation — always with the same goal: systems that bill correctly, provision reliably, and adapt as your roadmap moves.
We design and build BSS components and the glue between them — custom, extendable, and aligned to the business.
We bring a testing-first mindset to BSS: rigour that catches rating, charging, and integration defects before revenue is at risk.
We help operators make the right calls: where to invest, what to build, what to retire — with a clear, costed path.
Every engagement follows the same disciplined path. It keeps work predictable, measurable, and reviewable at each stage.
We map your current BSS landscape, revenue flows, and pain points. The output is a clear statement of where the real cost and risk sit.
We turn business requirements into a target architecture and a scoped delivery plan — the build is agreed before a line of code is written.
Agile delivery in small, shippable increments with continuous integration. You see working software early, not at the end.
Automated suites plus UAT and performance validation prove billing accuracy and integration integrity before anything reaches production.
Controlled rollout with operational support and a feedback loop, so the system keeps improving after go-live.
BSS is unforgiving — small defects leak revenue. We combine deep domain knowledge with hands-on engineering discipline.
Billing, charging, O2C, TMF-aligned thinking — we speak the language of carriers, not just the language of code.
We recommend and build for what fits your operation — not what a single vendor's licence says you should run.
Quality is engineered in from day one, with automation that protects revenue-critical paths against regression.
Turnkey delivery, dedicated teams, or staff augmentation — scaled to your programme and budget.
ML&MY Limited, trading as MLMY, is an engineering-led consultancy focused on Business Support Systems for telecom operators and service providers. We were founded on a simple observation: the systems that bill, serve, and retain subscribers are too often treated as an afterthought — until something breaks.
Our work spans the OSS/BSS stack, from convergent billing and charging to CRM, order management, mediation, and the integrations between them. We build where our clients need new capability, test where reliability matters, and consult where direction is unclear.
We are hands-on engineers first. That means honest estimates, working software, and systems our clients can actually operate after we leave.
Delivery owned by people who build, not by account managers selling time.
Every decision is tested against one question: does it make the operation run better?
We measure success in billing accuracy, provisioning speed, and lower operational cost.
Working with carriers and service providers across the UK and beyond.
