Selling on Rozetka and Prom, but manually re-typing every order into your accounting software? Do your marketplace stock levels live separately from your real warehouse, so every now and then you sell something that’s already out of stock? This is the classic chaos of multichannel sales. In short: ERP marketplace integration removes it — orders flow into your accounting automatically, while stock and prices sync with your warehouse without manual work. Below we break down how it works and what to watch out for.

Why does manual work with marketplace dashboards eat into your profit?

Because every order passes through a person twice: first the manager sees it in the marketplace dashboard, then manually enters it into your accounting system. In parallel, someone has to remember to reduce the stock count. At 30-50 orders a day, that’s hours of routine work daily plus a constant risk of error.

The most expensive mistake is overselling. Until the manager updates availability, the marketplace keeps accepting orders for a product that no longer exists. What follows is order cancellation, a damaged seller rating, and on some platforms financial penalties too. One such case costs more than a month of manual syncing.

The second hidden loss is that you don’t see the real picture. Revenue in the Rozetka dashboard, revenue in the Prom dashboard, revenue in retail — these are three separate reports. Combining them into a single margin that accounts for commissions, delivery and cost of goods is practically impossible by hand. Decisions about assortment and pricing get made on gut feeling rather than numbers.

What is ERP marketplace integration and how does it work?

ERP marketplace integration is a direct data exchange between your accounting system and the platform through its API. Instead of manual copying, data flows automatically: orders from the marketplace land in your accounting, while stock and prices from your warehouse are pushed back to the platform.

ERPJS supports the two key marketplaces for the Ukrainian market — Rozetka and Prom.ua. Here it’s important to distinguish two data flows, because they work differently. Orders and new buyers land in your accounting in real time — the manager sees them in the system immediately, with no manual entry. The product catalogue, stock and prices, on the other hand, sync on a configured schedule: not an instant exchange, but also completely free of manual work. There’s no manual labour in either direction.

It’s important to understand the boundary of responsibility. The marketplace is the storefront: it shows the product to the buyer and accepts orders. The ERP is the accounting layer: it stores the real warehouse, cost of goods, finances, and consolidates all sales channels in one place. The integration is the bridge between storefront and accounting.

How does automatic order import free up your manager?

An order from the marketplace becomes a document in your accounting system in real time, and a new buyer is added to your contacts database without the manager’s involvement. The person no longer re-types data — they work with the order right away: picking, preparing for shipment, generating the waybill.

In ERPJS, the full order lifecycle is implemented first and foremost for Prom.ua: new orders are pulled in automatically along with their statuses, and buyers not yet in your database are created automatically. For Rozetka, the focus is on syncing the product side — catalogue, prices and stock (more on that below).

What this gives you in practice: instead of being a “re-typist”, the manager becomes an operator who processes ready-made orders. The freed-up time goes to what actually brings in money — fast shipping, customer communication, repeat-sales work. And once an order is in accounting, it’s easy to pass it further down the chain — for example, to immediately generate a shipment through our Nova Poshta integration, closing the full “order → delivery” loop.

What does syncing stock between warehouse and marketplace give you?

The main thing is that one warehouse becomes the single source of truth for all sales channels. Sell a product at a retail point or on another platform, and availability on the marketplace updates at the next sync. The risk of overselling drops sharply, and along with it go the cancellations, penalties and rating drops.

ERPJS pushes to the marketplace not just the fact of availability but the quantity too, and the calculation logic can be tuned to your process. For example, send the full physical stock to the marketplace, or stock minus already-accepted orders, or stock minus reservations. This matters if you sell from one warehouse across several channels at once and want to keep a safety buffer.

Prices sync the same way: you maintain the price list in your accounting system, and the current value for the chosen price list is pushed to the marketplace. No need to edit a price in three places — change it once in accounting and it propagates across channels. This is especially valuable during promotions and rapid repricing. If you’re only just putting your warehouse in order, start with inventory management software — without accurate stock levels, any sync will push wrong numbers to the marketplace.

Why run marketplaces through an ERP rather than the built-in dashboards?

Because the marketplace dashboard only sees its own channel, while the ERP consolidates all channels together with warehouse and finances. The Rozetka dashboard doesn’t know about your Prom and retail sales; the Prom dashboard doesn’t know about cost of goods and delivery expenses. Only in the accounting system do you see the real margin per product, factoring in marketplace commissions, logistics and purchase price.

This is a fundamental difference in approach. The marketplace’s built-in tools are optimised for selling on that specific platform. The ERP is optimised for your business as a whole: how much you actually earn, which products drag you into the red after all commissions, where you’re overstocked and where you’re short. The marketplace answers the question “what is selling”, the ERP answers “how much am I making from it”.

For a retail business going online this is especially relevant: the physical point and the marketplaces should live off one warehouse and one accounting system. How to tell whether your store has already grown into this kind of automation, we covered in a separate article on accounting software for a store.

What should you consider before implementing the integration?

The main thing is realistic expectations about stock synchronisation. Orders and customers land in your accounting in real time, but the catalogue, stock and prices update on a schedule rather than instantly: between a sale in one channel and the availability update on the marketplace there’s a sync interval. For most businesses this is non-critical, but if you trade scarce, high-turnover items, the interval is worth thinking through separately.

Second — the integration requires setup tailored to your warehouse and prices. The basic exchange framework is universal, but the fine rules — which warehouse to take stock from, which price list to push, exactly how to create new customers — are configured to your process. This isn’t “switch it on and it works out of the box”, it’s a setup project, albeit a small one.

Third — start in phases. First launch stock and price syncing (this removes the most painful part — overselling and price mismatches), then connect automatic order import. That way you get results fast and don’t try to cover everything at once. We recommend this approach for any ERP implementation — more on choosing a system in how to choose an ERP system.
