Finance, inventory, manufacturing and HR modules delivered as one governed system — or integrated with SAP, NetSuite and Odoo.
Data warehousing, pipelines, forecasting models and applied AI embedded directly into operational workflows.
AWS and Azure landing zones, CI/CD, observability and hardened infrastructure audited against ISO 27001 controls.
Reference build · Premiere Systems ERP Core
Every platform we build ships with unified reporting, role-based access, full audit history and an integration layer that speaks to the tools you already own. Below is a production ERP and CRM console delivered for a multi-site industrial client.

Verified client reviews

"Premiere Systems replaced four disconnected spreadsheets and a 14-year-old ERP with a single platform in nine months. Their Krakow and Bangalore teams overlapped our working day almost completely, so we never lost a cycle. Inventory accuracy went from 82% to 99.4%."
"We had been quoted 18 months by two larger consultancies. Premiere Systems scoped a bespoke CRM, shipped a working pilot in seven weeks and had all 240 advisers migrated within five months. Their delivery lead ran weekly demos without fail."
"Manufacturing scheduling is unforgiving and their engineers understood it properly. The MRP module they built now runs three plants. Documentation and handover were the best I have seen in twenty years of buying software."
"Clinical data means zero tolerance for defects. Premiere Systems came in with test coverage discipline, a proper audit trail and passed our external penetration test first time. Two of their engineers are still embedded with us."
"Genuinely strong engineering and a well-run programme. The first month of discovery ran slightly longer than planned, though they absorbed the cost and the platform has been faultless since launch across 61 stores."
"They built our field engineer app, the customer portal and the back-office CRM as one connected system. Support since go-live has been the differentiator — a named contact, one-hour response, no ticket roulette."

About Premiere Systems
Premiere Systems was founded in London in 2018 by three engineers who were tired of watching enterprise projects fail in the handover. We kept the model deliberately simple: permanent engineers only, no subcontracting, one named delivery lead per client, and code you own outright from the first commit.
Today 292 people work under the Premiere Systems banner across four offices. Every engagement is governed from London, engineered across our European and Asian centres, and supported by a permanent operations team once live.
How we operate
Our teams work follow-the-sun. Work handed over in Bengaluru at 18:00 IST is picked up in Kraków, reviewed in London and demonstrated to North American clients the same business day. Every centre runs identical code review, security and QA standards.
