SolutionsReplacing ERP & old systems
Your old system holds you back.
Replacing it needs no cut-over date.
We record your existing ERP and the disconnected applications around it, secure what is known about your workflows and plan the replacement with ElbDesk - area by area, where technically possible. After the first engagement you know whether the switch is feasible, where to start and what effort to expect.
Four areas, each with a track for the old and the new system: orders are replaced, the warehouse runs in parallel and is highlighted, purchasing is recorded, accounts still work in the old system.
Typical situations
Does this sound familiar?
Especially when your system holds more than a feature list shows.
Your system is difficult to extend
New requirements stay unresolved, because every change can put established rules at risk.
Disconnected applications shape daily work
Spreadsheets and extra applications fill the gaps your old system leaves.
Support or knowledge is disappearing
The vendor has stopped development, or only a few people know the key rules.
Example of phased replacement
One area at a time. With planned transitions.
This is how replacement can work when areas can be separated technically.
The starting point
Orders and stock run in the old system, shipping in a separate application.

Shipping starts in ElbDesk. Warehouse and sales stay in the old system for now, connected through verified interfaces.

After testing and approval, the warehouse moves across. Sales remains connected for now.

Sales runs in ElbDesk too, and the replaced systems are retired. Required historical data remains accessible.

The sequence depends on your business, and we agree data migration, tests and approval for each stage.
The first engagement
Assess first.
Then decide on replacement.
Before a new system is developed, we examine a clearly defined first area.
Review the system and rules
With your team, we go through real transactions and record special rules, dependencies and data access.
After this you have
A description of your current system, including the open questions.
Choose the first area
We choose an area that makes business sense and can be separated technically.
After this you have
A reasoned recommendation for the starting point.
Plan implementation and transition
We describe data migration, testing, responsibilities and the switch.
After this you have
A plan for the switch, with a defined scope and an estimate.
Let us talk about which area could move first.
