After months of building, testing, and breaking things on staging stores, Nventory is officially live on the WordPress.org plugin directory.

This post is the honest launch story, what the plugin does, why I built it, what it doesn't do (yet) and what I'm hoping to learn from the dev.to community.
The Problem I Built It For
If you've ever run a WooCommerce store that sells on more than one channel — Amazon, eBay, Walmart, Etsy, TikTok Shop, Shopify, anywhere — you already know the pain.
You list the same SKU in five places. You sell one unit on Amazon at 11:47 AM. Fourteen minutes later, your sync plugin finally polls all the channels and updates them. By then, two more customers have bought that "available" unit on eBay and Walmart. You issue refunds, write apology emails, and get an Amazon account health warning for your trouble.
The existing solutions in this space are mostly:
Plugin stacks — install one plugin per channel, watch them fight each other over the WooCommerce stock table, end up with silent data corruption Polling-based sync tools work fine in demos, fail under real volume because 5–15 minute intervals aren't fast enough
Enterprise platforms overpowered and overpriced for stores doing under $1M ARR
I wanted something built specifically for the WooCommerce-plus-marketplaces use case, with webhook-driven sync, native channel integrations and a free tier that's actually usable, not a marketing funnel.
So I built Nventory.
What the Plugin Actually Does
The free WordPress.org plugin connects your WooCommerce store to a webhook-driven sync platform that handles:
Real-time stock sync across Amazon, eBay, Walmart, TikTok Shop, Etsy, Shopify and 30+ other channels
Variation-level tracking — every size/color/configuration gets its own SKU and its own sync rules
Bidirectional updates — sales on any channel reduce stock everywhere else in under 5 seconds
Order import — orders from every connected channel land in one operational view
Buffer stock configuration — reserve units per SKU as a safety net against sync delays
Audit logging - every webhook event, every stock change, fully traceable
What separates it architecturally from older plugins is that the heavy lifting (sync logic, retry handling, channel API coordination) runs on dedicated infrastructure, not on your WordPress hosting account. Your WooCommerce admin stays fast, even at 5,000+ SKUs.
What's in the Free Tier
I want to be specific about this because "free" means very different things from different vendors.
Free tier includes:
- Multi-channel sync to all 30+ supported channels
- Real-time webhook-driven updates
- Variation-level SKU tracking
- Order import from connected channels
- Standard support via the WordPress.org forum
No credit card required. No 14-day countdown that crippleware-locks the plugin. The free tier is built to be a real product for small-to-mid-volume stores, not a 14-day demo.
Paid tiers add multi-warehouse routing, advanced fulfillment workflows, custom reporting, and priority support. Most stores under 1,000 orders/month don't need any of it.
*The Architecture *
Since this is dev.to, here's the technical short version.
The plugin hooks into WooCommerce's native action system to capture stock change events:
phpadd_action('woocommerce_product_set_stock', 'nventory_handle_stock_change', 10, 1);
add_action('woocommerce_order_status_changed', 'nventory_handle_order_change', 10, 4);
Stock changes fire non-blocking webhooks to the Nventory platform, which fans them out to every connected channel in parallel. The platform handles the complexity that makes multi-channel sync hard: idempotency keys, exponential-backoff retries, HMAC signature verification, out-of-order event handling, and channel-specific API quirks (Amazon's SP-API throttling rules alone could be its own blog post).
The plugin itself stays lightweight. It doesn't poll. It doesn't run heavy cron jobs on your hosting. It listens for events and forwards them. Total plugin footprint is small, intentionally.
**What It Doesn't Do (Yet)
**I'd rather be honest about this than oversell.
No native ERP integration yet. If you need NetSuite or SAP-level workflows, this isn't your tool today.
B2B-specific features are limited. Wholesale pricing tiers, complex tax exemption logic, and BOM tracking aren't first-class features yet.
Some marketplace integrations are deeper than others. Amazon, eBay, Walmart, Shopify, and WooCommerce are very mature. Some of the smaller channels (specific regional marketplaces) are less battle-tested under high volume.
The roadmap is being shaped publicly based on user feedback. If something's missing that would unblock you, the WordPress.org support forum and nventory.io contact channels are both monitored.
What I'm Hoping the dev.to Community Will Help With
A few specific asks for anyone who reads this far:
- Try it on a staging store. If you run a WooCommerce store that sells on multiple channels, install on staging, connect a sandbox marketplace, and tell me what breaks. Real-world feedback from technical operators is the only way this gets better.
- Tell me what your current setup looks like. I want to understand what plugin stacks people have ended up with, what's working, what's not. Drop it in the comments.
- Be brutal in feedback. This is launch day. Issues you find now save real stores from headaches later. The harsher the feedback, the more useful it is.
- Suggest integrations. If there's a specific channel, 3PL, or accounting tool that would unlock your stack, I want to know. Why Launch on dev.to
Most launch posts go to Product Hunt, Twitter, or LinkedIn. I'm posting here because dev.to readers actually evaluate technical claims. I'd rather get torn apart by 50 thoughtful developers than upvoted by 500 people who didn't read past the headline.
If you've built or operated something similar, your perspective is what I'm here for.

Thanks for reading. Open to questions, criticism, war stories from your own multi-channel sync nightmares — all of it.
