Sync Product Data from Your ERP to Your Marketplaces

Before each sync, ERPkit computes a one-way hash of each product's syncable fields (price, compare-at price, weight, barcode). This hash is compared against the hash stored from the previous sync. If the hashes match, the product is skipped entirely — no API call is made.

This approach has three practical benefits. First, syncs are fast: a catalog of 2,000 products where only 15 changed results in 15 API calls, not 2,000. Second, you stay well within marketplace API rate limits, even with large catalogs. Third, the hash cache is disposable — if it is ever lost or cleared, the next sync simply treats every product as changed and rebuilds the cache. No data is lost, and subsequent syncs return to delta mode automatically.

Delta sync is built into every ERPkit plan. There is no configuration required — it works out of the box from your first sync.

Each Dolibarr product has a custom extrafield for each marketplace (for example, shopify_variant_id or woocommerce_variant_id). When this field contains a valid variant ID, ERPkit knows that product should be synced to that marketplace. If the field is empty, the product is silently skipped.

You can set variant IDs manually, or use the auto-match feature in the ERPkit dashboard. Auto-match compares Dolibarr product references against marketplace SKUs and links matching products automatically. For products with multiple variants or combinations, each Dolibarr product maps to exactly one marketplace variant — giving you precise control over which variant receives the update.

This design means Dolibarr is always the source of truth for product data. Your marketplace listings keep their titles, descriptions, images, and SEO content untouched. ERPkit only updates the four operational fields: price, compare-at price, weight, and barcode.

What product data does ERPkit sync?

ERPkit syncs four fields: selling price, compare-at (strikethrough) price, weight (with automatic unit conversion), and barcode (EAN/UPC). It does not sync titles, descriptions, images, or other presentation data. Your marketplace listings remain exactly as you designed them.

How often are products synced?

Sync frequency depends on your subscription tier. Each tier includes a different sync interval, and syncs run automatically on that schedule. You can also trigger a sync manually from the dashboard at any time. Each sync uses delta detection — only products whose data has changed since the last sync are sent to the marketplace, keeping syncs fast and predictable even with large catalogs.

Do I need to sync all my products?

No. ERPkit only syncs products that have a marketplace variant ID set in their Dolibarr extrafield. Products without a variant ID are silently skipped. You have full control over which products are linked and which are left alone.
