Create a 2-way product sync between GHL and WooCommerce via the GHL plugin

I own an art gallery as well as my marketing agency. We have a Wordpress website using WooCommerce and the GHL Plugin. But I don't sell all the products online directly. I don't want someone ordering a $110,000 piece of art online without proper vetting and discussion. So we create all products in WooCommerce on WordPress Website. That then syncs the products back in GHL. I use the GHL system for invoicing, estimates, and the mobile app for POS in the gallery itself. One main issue I have is that if we invoice a client in GHL, that reduction of inventory does not sync back to the Wordpress website. I have to manually update the inventory levels in WordPress for every sale. It seems like it would be a very simple fix to just have an option of 2-way sync for inventory quantities.

This should be possible programmatically, but I would not frame it as a simple GHL Workflow-only fix.
The cleanest setup would be to treat WooCommerce as the main source of truth for website inventory, then create a small custom bridge between GHL and WordPress/WooCommerce.
Right now, products can originate in WooCommerce and sync into GHL, which is great. The missing piece is the reverse inventory update when a sale happens inside GHL through an invoice, estimate, or POS transaction.
The practical solution would look like this:
- A sale is completed in GHL through invoice, estimate, or POS.
- GHL fires a webhook when the invoice/payment is completed.
- A custom integration receives that webhook.
- The integration reads the sold line items.
- It matches each GHL product to the correct WooCommerce product using SKU or a shared product ID.
- It updates the WooCommerce stock quantity through the WooCommerce REST API.
- It logs the sync and alerts someone if a product cannot be matched.
For an art gallery, I would definitely avoid matching products by title alone. Each artwork should have a unique SKU or artwork ID that exists in both WooCommerce and GHL. That way, when a $110,000 piece sells in person or through a GHL invoice, the system can safely reduce the correct WooCommerce inventory item without guessing.
I would also recommend that refunds, voids, or canceled invoices do not automatically restock the item at first. For high-value art, it is safer to flag those cases for manual review.
So yes, this is very doable with the WP/WooCommerce API and GHL webhooks/API. It is essentially a custom inventory sync bridge:
WooCommerce → GHL for product creation/sync
GHL → WooCommerce for inventory reduction after paid invoices/POS sales
The biggest things to build carefully are product matching, duplicate protection, logging, and failure alerts. If those are handled properly, this would remove the need to manually update inventory in WordPress every time a gallery sale happens through GHL.
