Integration of BAS with Rozetka, Prom.ua and other marketplaces

Do you sell on Rozetka, Prom.ua or several marketplaces at once? Then you know the pain of manually updating stock levels and transferring orders into your accounting system. Marketplace integration with BAS automates this process and saves you from overselling and errors. Let's break down how it works and which solution to choose.

Why integration is needed

Without automatic exchange, a manager manually transfers every order into the accounting program, and stock levels on the websites almost never match the actual warehouse. This leads to:

• overselling of goods that are already gone — and cancellations that damage the seller's rating;
• outdated prices on the marketplaces;
• managers wasting time on routine tasks;
• errors when entering orders manually;
• dissatisfied customers and lost repeat sales.

Integration solves this: data moves between the accounting system and the marketplace automatically, without any human involvement.

What exactly gets synchronized

Stock levels

When a product is sold offline or on another marketplace, BAS automatically updates the quantity across all channels. Overselling disappears, and the customer sees real availability.

Orders

New orders from Rozetka and Prom.ua automatically arrive in the accounting system as documents — with products, quantities, customer details and delivery method.

Prices

Changing a price in BAS automatically updates it on the marketplaces. You can set separate prices for different channels (retail, marketplace, wholesale).

Statuses

The order status (picked, shipped, tracking number) is sent back to the marketplace, and the customer sees up-to-date information.

Product cards

Names, descriptions, specifications and photos can be uploaded from the accounting system so you don't have to fill them in manually on every marketplace.

What solutions exist

Ready-made modules for BAS

There are specialized extensions that add exchange with Rozetka, Prom.ua, Allo and others to BAS. You configure the matching of warehouses and prices — and the exchange runs on schedule. This is the fastest path for a typical store.

Intermediate aggregator services

Platforms such as product flow management services act as a "bridge": on one side they connect to BAS, on the other — to dozens of marketplaces. Convenient when there are many channels and you need a single management window.

Custom integration via API

Rozetka and Prom.ua have APIs. For non-standard needs, you can order a custom integration that precisely matches your business processes, warehouse structure and pricing rules.

Exchange via YML/XML feeds

The simplest option is uploading a product feed from the accounting system, which the marketplace picks up on schedule. It's suitable when you only need to update the assortment and prices, without two-way order exchange.

What to look for when choosing

1. Two-way exchange. Whether not only products are sent to the marketplace, but orders are also returned to the accounting system.
2. Exchange frequency. Once an hour is enough for a small store; for high turnover you need an exchange every few minutes.
3. Number of marketplaces. If you plan to expand, choose a solution that supports many channels.
4. Item matching. How the system links your product to the card on the marketplace — by SKU, barcode or manually.
5. Stock reservation. Whether you can keep a separate reserve for online so that the offline register doesn't "eat" the last item.
6. Support. Who will help if the exchange breaks down in the middle of a sale.

Typical implementation mistakes

• SKU matching not configured — products get duplicated or aren't found.
• A single warehouse for all channels with no reserve — both offline and online "eat" the same stock down to zero.
• No test period before launching on the full assortment.
• Ignoring the alignment of units of measurement and VAT between the systems.

Specifics of working with Rozetka and Prom.ua

Each marketplace has its own specifics that are important to take into account when setting up the exchange:

• Rozetka. Works both through its own seller account and through the marketplace model. It has requirements for the quality of product cards, categories and specifications. Orders come in linked to the delivery method.
• Prom.ua. A popular platform for small and medium businesses with flexible product import via price lists in XML/YML format and via API. Convenient for a quick start to online sales.
• Other marketplaces. Allo, Kasta, Epicentr and your own online store on OpenCart, Horoshop or another CMS can also be connected to a single accounting system.

The main thing is to bring all channels into one accounting point so that BAS is the single source of truth about stock levels, prices and orders.

How much time and money this saves

A store with several hundred items and two or three marketplaces without integration spends hours of a manager's work every day updating stock levels and transferring orders. Automation removes this routine entirely, reduces the number of cancellations due to overselling and frees people up to work with customers. The investment in integration usually pays for itself within a few months.
