Supplier product import: ingest vendor files without reworking them three times

Onboarding a new supplier to your catalog is rarely fast. Between column mapping, data cleanup, image generation and description enrichment, every supplier costs 2 to 5 days. Here is how to divide that time by 4.

A multi-brand reseller works with 10, 50, sometimes 200 suppliers. Each sends their catalog their way: Excel by email, CSV on FTP, auto-generated XML feed, proprietary API. Harmonizing all of that for Shopify or PrestaShop is a full-time job.

This guide describes the supplier import workflow that saves 80% of the time our clients spend on this task.

The 4-step supplier import workflow

1. Visual mapping

Match every supplier column (ref_art, short_label, price_excl_vat_eur) to a Shopify or PrestaShop field (SKU, Title, Price). Conversion rules included.

2. Bulk cleanup

Upper/lower case, HTML tag removal, VAT/no-VAT conversion, unit normalization (cm vs mm), padding short SKUs.

3. AI enrichment

Description, meta title, meta description generation from supplier attributes. Rewriting poor titles into Google Shopping-ready ones.

Concrete example: 5,000-line supplier CSV

A fashion client receives every Monday a 5,000-reference CSV from their main supplier. Before Seegea: 2 people for 3 days to clean, map and publish. After Seegea: 1 person for 2 hours, the rest runs automatically via pre-configured rules.

  • Columns REF, DESIGNATION, PRIX mapped to SKU, Title, Variant Price
  • Supplier image URL downloaded, compressed, converted to WebP
  • Description generated by AI from designation and attributes
  • Shopify push in batches of 500 to avoid rate limits
Suppliers often send files in Windows-1252. Seegea auto-detects encoding and converts to UTF-8 before import. No more opening each file in Notepad++.

Why "supplier import + inline editing" changes everything

After a supplier import, you always find edge cases: 20 SKUs without image, 5 categories miscategorized, 3 titles too long. With a CSV-only workflow, you reopen Excel and re-import. With Seegea, you fix directly in the grid, push is instant.
