Start from real representative orders to verify every step through to the ERP before launch.
Your current site already handles recurring orders, customer agreements and data exchanges with back-office systems. When it is time to modernize or migrate, those existing workflows are your best starting material.
Rather than reviewing screens in isolation, preparation works best around a curated set of representative orders: a routine purchase, a contract-pricing account, a multi-warehouse split or an order sent from a customer’s own system.
Follow representative scenarios all the way to the ERP.
Every test scenario should be traced completely: is the right account recognized? Are pricing terms respected? Does the order land in the ERP with every detail operations need to pick and bill without manual fixes?
Integrations carrying the highest uncertainty belong near the front of the queue as soon as prerequisites are ready. A constraint from an external partner or a subtle pricing calculation can shape decisions elsewhere in the project.
Consider a pilot rollout when the environment allows.
Depending on your setup, launching first with a small group of pilot customers can help confirm real-world usage before opening the new portal broadly. Even then, orders, data ownership and any temporary coexistence between old and new sites need a clear plan.
At Progymédia, we map this transition alongside the people running daily operations so acceptance criteria, responsibilities and rollout steps stay explicit.
Before committing to a launch date
✓ Collect 5 to 10 representative orders spanning routine purchases and critical edge cases.
✓ Verify ERP and partner integrations early wherever requirements feel least certain.
✓ Define the concrete operational sign-off criteria that prove the new workflow is ready.
