Three stores. One clear decision workspace.

The project connects three Shoprenter stores, a Tharanis ERP system and three suppliers. Purchasing and selling data must also be compared with prices from one designated competitor.

The suppliers had no usable API. Products had to be found, matched and checked on their websites. Different pack sizes or uncertain matches can distort a price comparison, so verifying product identity became the foundation of the process.

We built a solution around the existing systems. Tharanis and Shoprenter data can be retrieved through their APIs; browser-based collection supports checks on supplier websites.

Verified product URLs are stored in a shared database, allowing the next check to begin from a known product page. Missing and uncertain matches remain visible and are never automatically marked as correct.

The dashboard brings available purchase, selling and competitor prices together with stock and availability in one product row. The decision list focuses on stock discrepancies and price differences above the agreed threshold.

A dedicated approval screen shows the current value, proposed value and reason for the change together. Each proposal can be checked before the merchant decides.

The checking cycle was prepared as six daily batches followed by a report on day seven. Task progress, blocked work and open questions can be followed in one place.

For goods receipt preparation, we built PDF upload and a persistent processing queue. Net unit prices can be edited on the itemised invoice; euro invoices can use an invoice-specific exchange rate. Changing a price draft requires a new approval.

The system also considers bundle compositions in Tharanis. When a matched invoice line is part of a bundle, it identifies the affected bundles. A verified increase in purchasing cost produces a separate bundle-price review proposal, accounting for the quantity of that component in each bundle.
