At 9 AM, the customer service team reaches the warehouse to fulfill an order from an e-commerce platform. The product shows as in stock in the system — but it's not in the warehouse. Stock shows 47 in ERP, 50 on the e-commerce platform, and in reality there are 45. Three systems, three different realities.
This situation isn't just an operational headache. A cancelled order means a lost customer. Wrong stock data means overselling. Overselling means returns, returns mean dissatisfaction, and dissatisfaction means a lower rating on the marketplace. The dominos keep falling.
Why Does This Happen?
Most manufacturing companies chose their ERP system years ago — back when e-commerce didn't exist or was marginal. Then a marketplace was opened, then a second one, then their own website… Each platform holds its own data, none of them talking to the others.
Most companies try manual synchronization as a fix: an employee compares systems every day and closes the gaps. This is slow, error-prone, and unsustainable. Because stock can change by the minute, while an employee can only check once an hour.
A Single Source of Truth
VAGUS's approach is based on a simple principle: there should be one source of correct data, and all other systems should feed from it. The ERP already existed at this company and was reliable — the problem was the disconnect between ERP and the marketplaces.
The system we built monitors every stock movement in the ERP in real time. When a product is sold, returned, or received into the warehouse, this change is reflected within seconds to the marketplaces and the company's own e-commerce site. No human intervention, no delay.
“A week after the system went live, the customer service team came to me and said 'We haven't had a single stock question.' At first I didn't believe it — we were so used to that question.”

An Unexpected Benefit
Beyond the stock sync, something else happened: for the first time, the company could clearly see which products were selling better where. Which marketplace has higher conversion in which category? Which products experience sudden sales spikes on certain days? Because this data is now real-time and accurate, purchasing and production planning started to change as well.
The integration solved a 'technical problem.' But its side effect was gaining strategic visibility.
