A roadmap, not a leap: How a rollout actually progresses
Key Takeaways
- Skipping a stage doesn't save time, it just moves the pain further down the road. Most OMS rollouts fail not because they're too ambitious, but because someone tried to shortcut the sequence.
- The rollout has four stages, but the same four-phase rhythm repeats inside every single one. Once you see the pattern, "big enterprise project" stops looking so intimidating.
- Going step-by-step is actually faster than going all at once, and it's not just intuition. Composable architecture, pre-built connectors, and smart piloting are the reasons staged rollouts beat big-bang ones on time-to-value.
In our last blog post, we talked about why enterprise OMS rollouts don't have to be big-bang projects. That raises the obvious follow-up question: if it's not one big leap, what is it?
The honest answer: it's a sequence of stages, each with a clearly defined scope. No shortcuts; skipping a stage doesn't save time, it just moves the pain further down the road, into a bigger and more complex stage later.
Here's what that actually looks like, phase by phase and stage by stage.
How every stage actually gets implemented
Whichever stage you're moving into, the implementation itself follows the same rhythm: four phases, repeated:
- Kick-off. Align key stakeholders on goals, use cases, and technical requirements.
- Discovery & design. Define and approve the target architecture, integration concept, and data model.
- Develop & testing. Implement, configure, and validate all features through end-to-end testing.
- Go-Live. Launch your project. Teams operate, agents decide.
This rhythm is what runs inside each stage. From stage to stage the rhythm stays the same, what changes is the scope. The stages can look different depending on the individual pain points
Stage 1: Basic Order Management
Goal: Automate order routing, digitize fulfillment processes, and establish a single source of truth for stock and orders.
Typical use cases:
- Introducing or replacing an OMS
- 360° order visibility
- Ship-from-store / warehouse
- Click & Collect from warehouse
Scope: Piloting of core locations.
This is where most rollouts start, not because it's the easiest part to sell, but because everything downstream depends on getting order visibility and routing right first. Piloting a limited set of locations keeps risk contained and gives both teams a working system to learn from before scaling.
Stage 2: Advanced Order Management
Goal: Professionalize order orchestration and roll out digitized store fulfillment to extend service level.
Typical use cases:
- Advanced routing configurations
- Customized routing by country or brand
- Detailed available-to-promise at checkout
- Real Click & Collect / Click & Reserve with ship-to-store backup
Scope: National rollout across brands.
Once the pilot proves the core logic works, Stage 2 is about scale and precision: routing that reflects real business rules (by country, by brand) and a checkout experience that can make accurate promises instead of generic ones.
Stage 3: Full Network Activation
Goal: Expand activation to external parties and enhance omnichannel processes to increase customer satisfaction.
Typical use cases:
- Connect to marketplaces and dropshippers
- Advanced delivery promise incl. reservations
- Advanced pickup options (Click & Meet)
- Same-day delivery
- Personalization of orders
Scope: Full network integration.
This is where the system stops being an internal tool and starts touching the wider ecosystem, e.g. marketplaces, dropshippers, same-day logistics partners. The complexity goes up, but so does what customers actually notice.
Stage 4: Entire Omnichannel Integration
Goal: Leverage store-specific and cross-store efficiencies to exploit full omnichannel potential and maximize revenue.
Typical use cases:
- Store-to-store shipment
- Backorders & preorders
- Enable BORIS (returns anywhere)
- Support endless aisle
Scope: Global scale and optimization.
The final stage is where the network starts working for the business instead of the business working around the network: cross-store efficiencies, flexible returns, and inventory that's genuinely usable from anywhere.
Why staging it this way is faster, not slower
It might sound counterintuitive: doesn't breaking a rollout into four stages take longer than "just doing it all at once"? In practice, the opposite is true, for a few concrete reasons:
- A modular, composable architecture means no rip-and-replace. Teams migrate step by step instead of switching every system over at once, which is what actually creates the multi-month projects everyone dreads.
- Piloting a single store cluster or channel first (see Stage 1's scope) demonstrates time-to-value quickly, instead of betting the whole rollout on a single go-live date.
- Pre-built connectors like the commercetools Marketplace Connector, cut down the custom development work that typically eats up the early stages of a project.
- Agents handle configuration and routing logic that used to require manual setup, which is part of why later stages (like Stage 2's advanced routing) don't require the same heavy lift they once did.
The bottom line
None of these four stages are optional, and none of them should be skipped to save time on paper. What determines whether a rollout feels risky or manageable isn't whether you attempt everything at once. It's whether each stage has a clear, contained scope before you move to the next one.

Get a deep dive with our Implementation Guide
Many order management projects are still planned like ten-year ERP rollouts: one big cutover, one big budget, one big risk. It doesn't have to be that way. Our guide walks through why traditional OMS projects stall, and the shifts that let you go live in weeks instead of months, without ripping out what already works.
FAQs
How long does an enterprise OMS rollout typically take?
There's no fixed timeline. It depends on how many stages and locations are in scope. Enterprise OMS rollouts are structured in different stages, each following the same four-phase implementation rhythm: Kick-off, Discovery & Design, Develop & Testing, and Go-Live. Staging the rollout is designed to shorten time-to-value, since teams see a working system early instead of waiting for one big go-live date.
Is it faster to implement an OMS in one big rollout or in stages?
Staged implementation is typically faster to value, not slower, despite seeming like the opposite. A phased rollout uses a composable architecture that avoids rip-and-replace migrations, relies on pre-built connectors (like the commercetools Marketplace Connector) to cut custom development, and lets teams pilot a single store cluster or channel first to prove the system works before scaling. A single big-bang rollout, by contrast, bets the entire timeline on one go-live date — which is usually what turns into the multi-month projects companies try to avoid.
