Features

Everything you need to stop overselling

Purpose-built for multi-channel sellers — not a bloated ERP, not a fragile spreadsheet. Just inventory that stays correct.

Real-time webhook sync

An order on any channel updates every other channel in under five seconds. No polling, no 10-minute windows where oversells slip through.

SHOSKUAMZ

SKU Mapper — cross-channel links

Pro plan · Powered by Claude

AI demand forecasting

30/60/90-day forecasts, reorder points, and dead-stock flags — each with a plain-English explanation of the reasoning behind it.

Main warehouseRetail floor3PLRead-only

Multi-location aware

Classify your Shopify locations — owned warehouse, retail floor, 3PL, read-only — and the sync engine reads and writes stock exactly where it should.

How it works

Up and running in an afternoon

No implementation projects, no onboarding calls required. Connect, map, and let the sync engine take over.

1

Connect your channels

Authorize Shopify, Amazon, and your other channels with OAuth — a couple of clicks each, no API keys to copy around.

2

Map your SKUs

Syncstocky auto-matches identical SKUs across channels. Link the rest by hand — every product ends up with one master SKU.

3

Sell with confidence

From then on it's automatic: every order, restock, or adjustment on one channel updates all the others within seconds.

AI forecasting · Pro plan

Forecasting that explains itself

Most tools give you a sales-velocity average and call it forecasting. Syncstocky uses Claude to analyse each SKU’s history and tell you what to reorder, when, and why.

30/60/90-day forecasts per SKU

Demand projections with seasonality and trend awareness, refreshed on request — 50 forecast runs per month on Pro.

Reorder points and quantities

Know when to reorder and how much, before a stockout costs you the sale — plus dead-stock flags for SKUs that stopped moving.

Reasoning you can read

Every forecast comes with a plain-English explanation of why — not a black-box number you're asked to trust.

Why Syncstocky

Built to a different standard

We’re not trying to be the biggest inventory platform — just the one independent multi-channel sellers can actually rely on. Four commitments define the product.

Real-time by architecture

Most inventory tools check your channels on a schedule and hope nothing sold in between. Syncstocky is webhook-driven at its core — a sale anywhere updates everywhere in seconds, because reacting instantly is the design, not a premium tier.

Priced for independent sellers

Transparent order-volume plans from $29/month, published openly. No sales calls, no custom quotes, no enterprise gatekeeping — a two-thousand-order store gets the same engine as an eighteen-thousand-order one.

Intelligence included

Claude AI demand forecasting is built into the Pro plan — not a paid add-on. And every forecast explains its reasoning in plain English, so you're making decisions with it, not deferring to a black box.

Built in public

Our roadmap is on the homepage, unfinished features are labeled 'coming soon' instead of hidden, and pricing never changes behind your back. You should know exactly what you're buying — before and after you buy it.

Three things. Speed: Syncstocky is webhook-driven, so stock updates land in under 5 seconds instead of waiting for a scheduled polling cycle. Intelligence: the Pro plan includes Claude AI demand forecasting that explains its reasoning in plain English — not just a sales-velocity average. And honesty: transparent order-based pricing from $29/mo, an open roadmap, and unfinished features clearly labeled rather than hidden.

Your plan is based on the total number of sales orders you receive across all connected channels in a rolling 12-month window. Starter covers up to 2,000/year, Growth up to 8,000/year, and Pro up to 18,000/year. Your dashboard shows your current usage so you always know where you stand.

We'll notify you when you're approaching your limit and give you the option to upgrade. We won't cut off your sync mid-month — your account stays active and we work with you to move to the right plan.

Shopify, Amazon, and eBay are fully live. Etsy and WooCommerce are in active development. Walmart is on the roadmap. More channels are added based on user requests.

Full access to your chosen plan — all channels, real-time sync, SKU mapper, and sync log. No credit card needed to start. AI forecasting is not included in the trial. If you don't upgrade, your account stops syncing at day 15.

Pro includes Claude AI-powered demand forecasting with 50 forecast calls per month. Each call analyses a SKU mapping and returns 30/60/90-day forecasts, a reorder point, reorder quantity, dead stock flag, and a plain-English explanation of the reasoning. Results are cached and you can regenerate any time — it counts against your monthly quota.

No — we only update inventory quantities. We don't create or modify your product listings, prices, titles, or images.

You connect one store per channel — your Shopify store, Amazon account, eBay account, and so on all sync into one shared inventory. Starter supports 2 channels, Growth 4, and Pro unlimited. Shopify multi-location setups are fully supported, and connecting several stores on the same channel is on our roadmap.

No. All plans are month-to-month. You can upgrade, downgrade, or cancel anytime — no penalties, no lock-in.

Your data is retained for 30 days after cancellation. You can export a full CSV of your sync history and SKU mappings at any time from your dashboard.

Stop selling stock you don’t have

Connect your channels and Syncstocky keeps every stock level aligned automatically — updates land in under five seconds.
