MES Buyer Guide
How to Choose an MES Software Vendor and Implementation Partner
Choosing an MES software vendor is one of the highest-stakes decisions an operations or IT leader makes. The wrong choice means a stalled rollout, brittle integrations and a system the shop floor refuses to use. This guide explains what to look for in an MES partner - and why an experienced engineering team matters more than a glossy product demo.
Ajinkya Technologies is an MES implementation partner with deployments that track 720,000 material movements per day and benchmark 40% faster transactions than leading global systems. Here is how we would tell any buyer to evaluate us - and everyone else.
Free scoping call. We start with one line, never change your machine logic, and you own the code and the data.
Product vendor vs implementation partner: know what you are buying
There are two very different things sold under the MES banner. A pure product vendor sells a licence and leaves integration to you or a third party. An implementation partner takes responsibility for making MES work in your specific plant - the connectivity, the integration with ERP, and the change management on the floor.
Most failed MES projects are not failures of the product; they are failures of integration and adoption. That is why an experienced engineering partner - one that connects machines, integrates ERP and earns operator trust - de-risks the project far more than feature checklists do.
- Can they integrate with your machines (OPC-UA, Modbus, MQTT, PLC, SCADA)?
- Can they integrate cleanly with your ERP (SAP, Oracle, Dynamics, custom)?
- Do they deliver source-code ownership, or lock you into a licence?
- Do their engineers actually spend time on shop floors?
- Can they show measurable outcomes from comparable plants?
What to look for in an MES partner
Insist on real shop-floor references and quantified outcomes - OEE gains, downtime reduction, dispatch accuracy - not just logos. Ask how they handle legacy machines, because every real plant has them. Confirm they can deliver electronic batch records and FDA 21 CFR Part 11 alignment if you are regulated.
Evaluate the engineering team directly. MES lives at the messy intersection of OT and IT; the partner that can speak both, and has shipped at scale, is the one that will get you to production and keep you there.
How to de-risk and phase your MES project
De-risk by starting with a focused proof-of-value on one line or cell - typically live within weeks - with clearly defined success metrics. Prove the connectivity, the ERP integration and operator adoption on a small scale before committing to a plant-wide rollout.
Then scale in measurable phases. This approach turns a high-risk, multi-year program into a series of self-funding steps, each delivering value your leadership can see on real dashboards.
Why work with Ajinkya Technologies
We are an MES implementation partner and engineering team, not a reseller. We connect machines and ERPs, deliver full source-code ownership, and have proven results at scale - 720,000 material movements per day, 16,800 paint barrels per hour via RFID, 40% faster transactions than leading global systems, and up to 60% manual-labour reduction across 360+ industrial clients.
Frequently asked questions
What is the difference between an MES product vendor and an implementation partner?
A product vendor sells the software licence and typically leaves integration and adoption to you. An implementation partner takes responsibility for making MES work in your plant - machine connectivity, ERP integration and shop-floor adoption. Most MES failures are integration and adoption failures, which is why the partner matters more than the feature list.
What should I look for when choosing an MES vendor?
Real shop-floor references with quantified outcomes (OEE, downtime, dispatch accuracy), proven machine and ERP integration, handling of legacy equipment, regulatory capability (e.g. FDA 21 CFR Part 11 electronic batch records) if needed, and source-code ownership rather than lock-in.
How do I reduce the risk of an MES implementation?
Start with a focused proof-of-value on a single line or cell with defined success metrics - usually live within weeks - to prove connectivity, ERP integration and operator adoption before scaling plant-wide in measurable, self-funding phases.
Why is an experienced engineering team so important for MES?
MES sits at the intersection of OT (machines, PLCs, SCADA) and IT (ERP, databases, cloud). A partner that genuinely speaks both and has shipped at scale will get you to production and keep you there - which is far more predictive of success than a product demo.

Common concerns, answered
Will this disrupt production?
No. We connect read only first, install during planned stops, and edge devices buffer data so a network problem never stops a machine. Nothing writes to a PLC without your controls team and a test.
Our machines are old. Do we need to replace them?
No. Old machines are the usual case. A running signal, a cycle signal or a current sensor on the motor is enough to start, without touching the machine program.
We tried a system before and nobody used it.
That is the most common failure, so we design with the operators and supervisors who will use it, start with one report they already fill in by hand, and only extend once they rely on it.
What about IT security?
Read only by default, a segmented OT network, and a review with your IT team before anything connects, following the ISA/IEC 62443 zone approach.
We will not replace SAP or Oracle. Do we have to?
No. We connect to the ERP you already run through its standard interfaces and add what the shop floor is missing. Your ERP stays the system of record.
Do your engineers understand a heavy industrial floor?
Our systems run in steel plants, warehouses and process lines. We start every project by walking the line with your operators and supervisors, and the first release is tested by them, not only by IT.
Are we locked in?
No. You own the source code and the data, documented, in your own repository. Another team can maintain it.
