Interim Project Manager OMS & Marketplace Integration
Interim Search AB has been commissioned to find an interim Project Manager OMS & Marketplace Integration for a multinational industrial company.
You report to the Chief Digital Officer (CDO).
The goal of this project is to build a central Order Management System (OMS) that:
- receives orders from a marketplace
- acts as reseller towards the marketplace partner
- orchestrates fulfillment via multiple dismantlers using a drop-shipment model
- supports summary invoicing, supplier self-invoicing, and EU VAT complexity
The partner relationship is strategically important, and the solution must be correct, auditable, and scalable from day one.
Main tasks:
- Responsible for delivering a high-confidence Order Management System (OMS) integration with a strategic marketplace partner, reducing delivery, financial, and operational risk ahead of go-live
- Validate and strengthen the end-to-end OMS design
- Confirm correct handling of:
- order and line lifecycles
- inventory reservation and supplier acceptance
- partial fulfillment and exception handling
- summary invoicing, credits, and supplier self-invoicing
- EU VAT reverse charge and cross-border trade flows
- Identify and mitigate scale, audit, and financial risks
- Help the team move from MVP to go-live without architectural rework
- Review and challenge OMS, pricing, logistics, and financial flows
- Responsible for pressure-test edge cases and failure scenarios
- Validate integration boundaries between OMS, ERP, accounting system and marketplace
- Provide concrete, actionable guidance to product, tech, and finance teams
- Act as a sparring partner to digital and delivery leadership
To be relevant for the role:
- You must have experience from personally building or leading an OMS-implementation for:
- marketplace or multi-seller models
- drop-shipment or distributed fulfillment
- high-volume order-line processing
- You combine strategic thinking with hands-on contribution
- You must have deep understanding of:
- separation of order, shipment, invoice, and payment lifecycles
- summary or consolidated B2B invoicing
- credit notes, refunds, and reconciliation
- supplier settlement and self-invoicing models
- You have practical EU VAT experience
- You are comfortable working with accounting integrations (Visma and/or Fortnox) and complex, industry-specific legacy systems rather than standard Tier-1 ERPs
- You are fluent in English and Swedish, oral and written
- It’s a merit if you have a marketplace background from large B2B or B2C platforms
- It’s a merit if you have experience in PE-backed or high-pressure scale-ups
