21 yrs In independent QA No implementation arm, since 2005

Your ERP updates on its schedule.
Not yours.

Microsoft ships Dynamics 365 continuously. Oracle ships quarterly. Workday ships twice a year plus weekly. We validate the business processes running through your ERP before every one of those updates reaches production — on one annual package, not a quote per release.

Where releases break

A screen can pass every check and the business process still fails.

Four patterns we see consistently, across D365, Oracle and Workday.

01

Customisation regression

Vendor updates to core frameworks need testing against every customisation you run.

  • BOM and route regression
  • Custom workflow validation
  • Extension compatibility
02

Integration failures

MES, WMS and CRM connect through APIs that an update can silently version-bump.

  • API version compatibility
  • Goods receipt & transfer sync
  • ISV and Power Platform links
03

Cost accounting & GL posting

Cost reconciliation, WIP posting and variance reporting rely on exact configuration.

  • Posting logic regression
  • Multi-entity consolidation
  • Financial close accuracy
04

Procurement & approvals

Three-way matching and approval hierarchies are what teams feel first when something breaks.

  • Three-way match validation
  • Approval hierarchy regression
  • Vendor invoice workflows
What we do

Three ways enterprises bring us in.

No implementation arm, and none since 2005. Three practices, one discipline: find what breaks before your users do.

01 / LEAD PRACTICE

ERP Release Testing

Validated at the business-process level before every vendor update reaches production, with a go/no-go readiness decision you can defend to the board.

Explore ERP Release Testing
02 / GLOBAL REACH

Globalization & Localization QA

Internationalization, localization and culturalization for products shipping into multiple languages and regulatory regimes — the discipline behind a four-year-plus engagement with Adobe.

See how we test globally
03 / AT SCALE

Dedicated QA Teams

Functional, automation, performance, security and accessibility specialists inside your sprints and release cadence, governed as a Testing Centre of Excellence rather than resourced ad hoc.

How embedded teams work
Platforms

Testing across the enterprise landscape.

Dynamics 365 F&O is our deepest practice. Oracle and Workday extend the same discipline.

About the Opkey partnership

How we test Workday

How we deliver. Our test engineers build and maintain the pre-built ERP test assets, executed on the Opkey automation platform and integrated into your Azure DevOps pipeline.

What you are absorbing

Three vendors set the calendar.
You absorb all of it.

Each one ships on its own rhythm, and every update can change how finance, procurement and supply chain behave in production.

One annual package per platform, build included.

Rather than scoping regression testing again every release, we cover the year — and the year-one automation build sits inside the annual fee.

YoursThe test suite and assets stay in your environment
Dedicated QA Teams

Teams that stay long enough to know your systems.

Embedded teams inside enterprise organisations, sized to the programme.

Testing Centre of Excellence

Embedded, not outsourced

Engineers work inside your sprints and tooling, with your product context.

Full-spectrum skills

Functional, automation, API, performance, security and accessibility, from a 120+ bench.

Governed delivery

CMMI Level 3 and ISO 27001 governance, not ad-hoc resourcing.

Scales with the programme

Teams flex through programme phases, from a small pod to large multi-workstream engagements.

The same people, release after release.

Our longest client engagement has run 17 years. That only works when the team holding your test suite knows why each assertion is there — which is the argument for continuity over cheapest-available resourcing.

Business-process understanding

We test the logic behind the operation, not just whether the screen loads.

Independent by design

We don't implement ERP, so we're never signing off on our own build.

Relationships that last

Our longest engagement has run 17 years and is still active.

QA Health Check

Not sure your ERP is ready for the next update?

We review your environment and flag the highest-risk gaps before the next release reaches production.

What the Health Check covers

  • Regression coverage gaps across your critical processes
  • Customisations and integrations in the release blast radius
  • Testing maturity assessment against your release cadence
  • A prioritised action plan, not a sales deck
