ERP Modernization for a Multi-Location Wholesale Distributor

Client situation

A wholesale distributor operating across multiple retail locations ran its own ERP system integrated with a national retail partner's point-of-sale network, but the integration and its reporting had accumulated real, tracked defects as the business grew.

Business problem

Point-of-sale integration issues were surfacing as customer-facing failures (cart errors, incorrect tax calculation on certain product lines) and location-level inventory valuation reports were not producing reliable numbers -- undermining the multi-location reporting the business needed to run on.

Constraints

• A live retail POS integration with a national hardware retail partner that could not be taken offline to fix.
• Multi-location price-group and tax-rule logic that had to stay correct per location, not just in aggregate.
• A barcode-driven picker/fulfillment workflow already in use by warehouse staff.

Q-Solutions approach

1. 01.Triaged and tracked defects against a maintained issue log rather than ad hoc fixes, prioritizing customer-facing POS failures first.
2. 02.Rebuilt the tax-calculation logic for the affected product lines and validated it against real transaction cases.
3. 03.Corrected per-location inventory valuation reporting so it reconciled against actual stock movement.
4. 04.Modernized supporting infrastructure (server and database version currency) alongside the application-level fixes.

Delivered solution

• A stabilized retail POS integration with a national hardware retail partner.
• A barcode-driven picker application for warehouse fulfillment.
• A guest checkout flow alongside the existing account-based flow.
• Corrected multi-location price-group and tax-rule logic.
• Working per-location inventory valuation, sales, customer, tax, and collection reporting.
