Two ERPs, four sites, one Odoo — in nine months.

An energy distributor was running two incompatible ERPs across four sites. Consolidation onto a single Odoo unified operations without halting them.

The challenge

Four sites, two systems, no single truth.

Growth by acquisition had left the distributor with two different ERPs. Two of its four sites ran one system; the others ran another. Consolidated reporting meant exporting from both and stitching the numbers together in spreadsheets — slowly, and never quite the same way twice.

Inter-site transfers were especially painful: the same goods existed under different codes in different systems, so stock never reconciled cleanly across the group.

The brief was to standardise on one platform across all four sites — without a big-bang shutdown that would interrupt distribution.

Our approach

One platform, rolled out site by site.

We standardised the product and partner master data first, then migrated each ERP into a single Odoo with a reconciliation report signed off before every cutover. Rather than switch everything at once, we rolled out site by site so distribution never stopped.

  • Unified master data across all four sites
  • Staged migration with per-site reconciliation sign-off
  • Multi-company, multi-warehouse Odoo configuration
  • Both legacy ERPs decommissioned after parallel-run

Each site ran in parallel just long enough to trust the numbers, then the old system was switched off.

The results

One set of numbers, finally.

Nine months after kickoff, all four sites ran on one Odoo and both legacy ERPs were retired. Group reporting that used to take days of spreadsheet work became a live dashboard. Inter-site transfers reconcile because there is now only one set of product codes.

Weasydoo replaced two ERPs with one Odoo in nine months — and we haven't looked back. They ship what they promise.
