Resources5 signs you need Unified Commerce before ERP migration
The five warning signs that your B2B business needs a unified commerce layer before you touch the ERP — so the migration stays a back-office project instead of a customer-facing crisis.
Migrating or upgrading an ERP is a critical step for any industrial B2B company. It is also the project most likely to pull everything else into its orbit: if digital sales and operations aren't unified first, the transition becomes messy, costly and disruptive — and the disruption lands on customers rather than on the project plan.
The order of operations is what decides that. Put a commerce layer in front of the ERP and the migration becomes a back-office change: orders keep flowing, prices stay right and customers never see the seam. Migrate first and the storefront inherits every gap in the new system of record while the business is still learning it.
Companies that took the layer-first route have the numbers to show for it. With unified commerce in place, Damstahl and Vargus scaled digital orders tenfold, removed the equivalent of 48 full-time roles from manual order handling, and held business continuity through an ERP migration rather than pausing for it.

The five signs
None of these is a reason to delay the ERP project. Each is a reason to put the commerce layer in first, because each describes a problem the new ERP will not solve on its own — and in some cases one the migration will make worse before it makes it better.
Automate before you migrate. Unified commerce takes order entry, pricing and approval workflows off the sales desk before the ERP project starts, so the team going through the transition isn't already at capacity.
A commerce layer bridges them. Customers and sales see one catalog, one price and one stock position; behind it, the systems can stay different — or be consolidated later, on IT's timetable rather than the customer's.
Steel and aluminium prices move daily and an ERP price list does not. Unified commerce manages complex pricing rules and market movement outside the ERP, so a cost change reaches customers without an ERP release.
A self-service portal survives the transition. Order history, invoices and certificates stay available to customers throughout, because they are served by the commerce layer rather than by whichever ERP happens to be live that week.
This is the sign that matters most, because it is self-inflicted. Unified commerce works across the old and the new ERP at once, which turns "not during the migration" into "during the migration, safely".
Why act now
ERP migration projects run long. Months of them leave sales teams overwhelmed and customers frustrated, and every month of waiting is a month the digital channel isn't compounding. Unified commerce protects digital sales continuity before, during and after the migration — which is precisely the window in which most companies decide to do nothing.
Vargus is the proof that the two projects can run together. It implemented unified commerce during its ERP migration specifically to maintain digital sales continuity, and it now unifies data from five ERP systems across several countries behind one storefront. You do not need a finished ERP landscape to modernise the customer experience.
What the layer does that the ERP cannot
Slize is composable and modular rather than monolithic: it integrates with the systems already in place — ERP, PIM, CMS, authentication — through APIs, which is what avoids vendor lock-in and lets it manage millions of product requests a day without the ERP carrying that load.
Pricing is the clearest example of the division of labour. The ERP stays the system of record for cost and contract terms; the commerce layer is where those become a price a customer can see, in real time, without a manual update.
The pricing engine handles volatility with:
- Repurchasing Cost (RPC) — pricing that follows current material cost in real time
- Management RPC (MRPC) — quick manual adjustment for a market opportunity or an added discount
- Granular rule-based pricing — rules at attribute level: grade, size, tolerance, loyalty
- Pricing templates — bulk configuration by customer segment
- Quantity-based pricing — margin that adjusts with order volume
- Real-time margin visibility — sales sees cost and margin at the point of quoting
The effect shows up on both sides of the ledger. Damstahl saw 24% higher gross profit on digital orders than on phone orders with that engine running, entered orders 80% faster, and automated more than 80,000 manual order lines a year — the 48 full-time roles' worth of work above. Today 95% of its orders are digital.
Where to start
If several of the five signs are familiar, the sequence is more important than the scope. Take the load off the sales desk first, bridge the systems second, and let the ERP project proceed underneath a channel that is no longer depending on it.
- Automate order entry and pricing before the migration begins
- Put one catalog, price and stock position in front of every ERP you run
- Move order history, invoices and certificates into self-service
- Keep the layer live across the old and new ERP, and cut over behind it
