Won't the import overwrite descriptions we have edited?

No, as long as we agree in advance which fields the import may change. We set a source for each field: for example, price and stock level always come from the supplier, while the import doesn't touch names, descriptions and photos you have edited in the online store. This matters for search engines too, as the descriptions you have written stay in place.

What if the supplier's file has no EAN or other unique codes?

Then we match products by supplier code, and if there isn't one either, by a combination of name and attributes. This kind of matching is less reliable, so unclear products are sent for review rather than created automatically. It's often worth asking the supplier to add codes to the file.

Will you import product photos as well?

Yes, if the supplier provides photo links and allows them to be used. Photos are downloaded to your server and resized, so they load quickly and don't depend on the supplier's website. After that, only changed photos are updated.

Will the import still work if the supplier changes its file structure?

Not always. If field names or the structure change, the import stops, you get a notification, and your existing data stays unchanged. We then adapt the import to the new structure – under a maintenance agreement or as a separate job. Minor changes, such as a new category, are handled in the rule settings without any coding.

Can we import only some of a supplier's products?

Yes. You can import only selected categories, brands, a price range or products with stock above a set level. That keeps your range tidy and your store free of thousands of products you don't need.

Product import and sync (XML, CSV, API)

Product import means automatically bringing supplier products, prices, stock levels and photos from XML or CSV files and supplier APIs into your online store, following your rules and schedule. Saitai.lt builds product import and sync for WooCommerce, VirtueMart and custom online stores. We set the price after assessing your suppliers' data; the timeline is 2–6 weeks.

Who it’s for

Every week, you spend several hours transferring supplier price lists into your online store.
You sell products from several suppliers, and their files differ in structure, categories and attributes.
You sell products the supplier no longer has, because stock levels in your store aren't updated often enough.
Your range runs to thousands of products, so you can no longer keep up with creating new ones by hand.
You calculate prices using mark-up rules that vary by supplier or category.
You work on a dropshipping model, with the supplier shipping straight to customers, so your online store has to show the supplier's exact stock level.

When it’s not the right fit

The supplier only provides data as a PDF price list or by email, with no structured data file. Then automatic import isn't reliable – it's worth asking the supplier for an XML, CSV or Excel file first.
You have a few dozen products, and prices change once a year. Then it's simpler to update them by hand or with a one-off import.
The supplier's terms prohibit using their photos and descriptions. Then we import only prices and stock levels, and you will have to prepare the content yourself.

Included

What you get

Supplier data analysis

We examine each supplier's file or API: which fields it contains, how often it's updated and whether products have unique codes (EAN, supplier code).

Category and attribute mapping

We map supplier categories and attributes – for example, colour, size or power – to your online store's structure, so that filters work the same way for every product.

Mark-up and pricing rules

Mark-up by supplier, category or price range, rounding and a minimum price – the final price in your online store is calculated automatically.

Stock levels and discontinued products

Stock levels are updated on a schedule, and products the supplier no longer has are hidden or marked as awaiting stock – whichever you prefer.

New products as drafts

New products are created as drafts with photos and a description, so you can review or add to them before publishing.

Several suppliers for the same product

If several suppliers offer the same product, a rule picks whose price and stock level to show – for example, the cheapest of those that have it in stock.

Import log and notifications

You can see how many products were created, updated and hidden. If a supplier's file is unavailable or corrupted, you get a notification, and your existing data stays unchanged.

Guide and a 12-month warranty

We show you how to change mark-up rules and map a new category. For 12 months, we fix import bugs free of charge.

Price

How much does supplier product import cost?

Price

On request

We price product import individually, after assessing your suppliers' files or APIs, the number of products and how complex the rules are. The assessment is free: send us a sample supplier file or API documentation, and within 1 working day we'll tell you how much the import would cost and how long it would take.

Prices include all taxes – no VAT is added (we are not VAT-registered). We put the price and timeline in the contract before work starts.

What the price depends on

How many suppliers, and how many different file formats or APIs, need processing.
How many products and variants are imported, and how often they need updating.
Whether the supplier data is tidy: unique codes, consistent attributes, working photo links.
How complex the mark-up, category and product selection rules are.
Whether descriptions and photos need importing too, or only prices and stock levels.
Whether several suppliers offer the same product and one offer needs to be chosen.

Additional costs

If a supplier charges for access to its API or data file, that fee is paid directly to the supplier.
A large catalogue may need a more powerful hosting plan, as frequent imports put a load on the server – we assess this before signing the contract.
New suppliers and rule changes after launch – under a separate quote, confirmed in writing.

Timeline

How long does it take to set up product import?

An import from one supplier with a tidy XML or CSV file takes 2–3 weeks; from several suppliers with different structures, product variants and complex rules, 4–6 weeks. The timeline runs from receiving the deposit and access to your suppliers' data.

Scope	Example	Timeline
One supplier	one XML or CSV file: prices, stock levels, new products	2–3 weeks
2–3 suppliers	different file structures, category mapping, mark-up rules	3–4 weeks
Many suppliers or APIs	product variants, several suppliers for the same product, thousands of products	4–6 weeks

Examples

Typical projects

Bike parts store with three suppliers

Situation: For example, a bike parts online store buys from three suppliers: one provides data as an XML file, another as CSV, and the third via an API. The suppliers call the same part by different names and sell it at different prices.
Solution: Products are matched by EAN code, and the store shows a single offer – the price of the cheapest supplier with the item in stock, plus your mark-up.
Result: One product page instead of three, a competitive price and stock levels that match the suppliers' real quantities.

Dropshipping store with a large catalogue

Situation: For example, a home and garden store works with a supplier that ships products straight to customers. The supplier's catalogue has tens of thousands of products, and stock levels change several times a day.
Solution: Only changed stock levels and prices are updated every hour, and the full catalogue every night. Only products from selected categories are imported, and new products are created as drafts.
Result: Up-to-date stock levels without unnecessary server load, and a curated range instead of the supplier's entire catalogue.

Plumbing wholesaler's price list

Situation: For example, a plumbing supplies wholesaler receives a new price list from the manufacturer every month as an Excel file, and the sales manager spends two days changing prices in the store.
Solution: The price list just needs uploading in the admin area: the system compares it with existing products, shows the prices that have changed, and publishes the new prices with mark-up only once you approve them.
Result: Prices updated in minutes, with a chance to review the changes before they go live.

Send us a supplier file – we'll assess it for free

FAQ

Frequently asked questions

As often as the supplier and your server allow: stock levels are usually updated every hour or several times a day, and the full catalogue every night. If the supplier has an API, some data can be updated even more often. We update only the products that have changed, so the import doesn't overload your store.
