Senior Microsoft Dynamics Business Central – Retail Discovery & Solution Architect (Contract)
Engagement: Contract | Outside IR35

Location: UK-based, client-facing as required
The Requirement
We are urgently seeking a senior, consultant-grade Microsoft Dynamics specialist to lead a short, fixed-price discovery engagement for a complex retail organisation preparing for a major ERP transformation.
This is a true consulting role – not delivery support. The successful contractor must be able to lead discovery, define target-state architecture, and shape a credible transformation proposal for board-level decision making.
What You’ll Be Doing
You will lead a 2–3 week discovery covering:
* Rapid assessment of the current ERP, POS, WMS, and ecommerce landscape
* High-level business and technical requirements
* Definition of a target-state SaaS Business Central architecture
* Options for delivery and support models (in-house vs supplier vs hybrid)
* A high-level roadmap and indicative cost estimates
* Clear, board-ready outputs and recommendations
You will work closely with Experis but own the solutioning and architecture.

* Multi-country retail operation (c.20 stores)
What the Client Wants
* Migrate to SaaS Business Central with minimal customisation
* Simplify and consolidate the ERP / POS / WMS landscape
* Rationalise and migrate only essential data
* Use standard ISVs and connectors wherever possible
* Reduce vendor lock-in and upskill internal teams
* Define a clear roadmap by Jan–Feb 2026
* Target implementation start April 2026
