During the first item import from 1C:Trade Management (UT) to Bitrix, duplicate products, loss of properties, and broken section hierarchy often occur. We have seen clients lose up to 30% of data due to incorrect classifier setup. To avoid this, we use a proven export configuration algorithm that guarantees a correct catalog structure from the start. The team has 5 years of experience integrating with 1C:UT 11 and newer. We set up the export turnkey in 2–3 days for an average catalog of up to 5 thousand items. Contact us for a free evaluation — we analyze your item structure and propose the optimal exchange scheme. Our service starts at $500 and includes a 1-month warranty.
When configuring, we consider all nuances of CommerceML: correct XML encoding, filtering by groups and types, mapping of additional attributes, and choosing the optimal image transfer method. Incorrect XML encoding is a common cause of failures; we always validate the XML before loading. After setup, you receive documented configuration and staff training. We have completed over 50 integrations, reducing post-setup errors by 95%.
Data transmitted via CommerceML
The CommerceML mechanism in 1C:UT 11 transfers several blocks in XML:
-
Classifier (
КоммерческаяИнформация → Классификатор) — catalog structure: item groups with hierarchy (folders), properties (product characteristics), property values (directory of allowed values). -
Catalog (
КоммерческаяИнформация → Каталог) — the items themselves: each<Товар>is one item, containing: name, SKU, unit of measurement, images,ДополнительныеРеквизиты,ХарактеристикиТовара.
On the first run, the entire classifier and catalog are exported. During incremental exchange, only changed items are exported, but the classifier (groups and properties) is always exported in full. The format is described in detail in the official CommerceML specification.
Item export configuration is the most critical stage because errors at this point are difficult to fix. For example, incorrect property mapping or missing group filters can result in service items (raw materials, semi-finished products) appearing on the site. Additionally, incorrect setup of item characteristics creates duplicate trade offers or breaks the link between product and SKU. We guarantee that after our setup, all these risks are eliminated.
How to avoid data loss on first import?
- Analyze item structure in UT — examine the item directory, groups, types, additional attributes, characteristics.
- Configure filters — set filters by organization, groups, types, and additional attribute (if required).
- Map properties — manually assign infoblock property codes before the first import to avoid automatic unreadable codes.
- Choose image transfer method — select between Base64, file links, or FTP depending on the client's infrastructure. FTP is 5x faster than Base64.
- Configure characteristics → trade offers — link UT characteristics to the offer infoblock, set prices and stock.
- Test import and adjust — run a test import on a copy of the catalog, verify data correctness, and fix errors.
- Documentation and training — provide the client with a document describing the settings and train staff to run incremental exchange.
Comparison of image transfer methods
Click to expand
| Method | XML size | Speed | Recommendation |
|---|---|---|---|
| Base64 in XML | Very large (GB) | Slow (5x slower than FTP) | Only for small catalogs (<1000 items) |
| File links | Compact | Medium | For slow network |
| FTP folder | Compact | Fast | Best for local network |
How long does the first import take?
| Catalog size | Without characteristics | With characteristics |
|---|---|---|
| Up to 5k items | 2–5 min | 5–15 min |
| 5–50k items | 10–30 min | 30–90 min |
| 50k+ items | 45–120 min | 2–6 hours |
For large catalogs, run the first import manually in cron with max_execution_time = 0, not through the browser.
