Why I built this
Sure, you can manage inventory on Excel —
Sure, you can manage inventory on Excel —
if you only have a handful of SKUs.
For over a decade — across large corporations, multinationals, and startups —
I've forecasted demand mostly in Excel.
The problem was Excel itself: add a few SKUs and it slowed to a crawl, a few formulas and it buckled — freezing mid-save, even wiping out my work.
So I built Innostock — it forecasts demand fast and accurately, however much data you have, and tells you exactly which SKUs to reorder, and how many.The era of running inventory on Excel is over.

The usual fixes — and their limits
ERP only records the past —
ERP only records the past —
it doesn't forecast future demand.
| Criteria | Hire more staff | ERP·WMS | Innostock |
|---|---|---|---|
| Cost | High | High | No implementation costs |
| Setup | – | Not needed | |
| Reliable demand forecasting | |||
| Fits SMB sellers |
Hiring more people still leans on one person's skill — and when they leave, the know-how leaves with them.
Built for
If this sounds like you, Innostock fits.
Multi-channel sellers
Tired of managing inventory separately across Amazon, Shopify, Shopee, and more.
Seasonal & trend sellers
Demand swings make it hard to time your orders right.
Teams ordering on gut feel
The data is piling up, but forecasts still rely on experience and intuition.
Features
Manage inventory like a pro
Expensive, complex software only slows you down — it takes forever to learn,
and you'll end up using less than half of it anyway. So we built in only what you truly need.

How it works
From data upload to demand forecasts in minutes
Three steps. No complicated setup — start right away.
01
Upload your sales history
Fill our sample template with your data and drag-and-drop the Excel or CSV. Just move the order history you exported from Amazon, Shopify, Shopee, and the like into it — all we need is date, SKU, and quantity.
02
Auto-forecast every SKU
In seconds to minutes, generate 12-month demand forecasts for every SKU, viewable by channel.
03
Add stock & lead time → reorder plan
Just enter your current stock and lead times, and we'll factor in in-transit and safety stock to tell you exactly how much to order this month.
What changes
Get demand right, and your cash flow changes.
Cut stockouts and overstock, and both your sales and cash flow come alive.
Fewer stockouts → more sales captured
See demand coming and reorder in time, so you never miss a best-seller and recover the sales you used to lose.
Less overstock → cash freed up
Filter out what won't sell, and recover the cash locked in inventory to put it where it actually matters.
Premium demand & ordering plan
Simple, transparent pricing — no hidden costs
Losing sales to stockouts — do you know how much?
A company doing ₩10B a year recovers about ₩500M in annual sales by cutting stockouts just 5% — and frees capital tied up in excess stock.

Frequently asked questions
How is this different from ERP or Excel?
ERP is a tool for recording the past. Innostock learns from that data to predict future demand — and tells you exactly when and how much to reorder. And unlike spreadsheets that slow down or freeze as SKUs and formulas pile up, Innostock handles far more data, fast.
Is it complicated to set up?
There's no installation or implementation. Just upload your sales history as an Excel or CSV file, and you'll see forecasts within minutes.
Does it integrate with ERP or e-commerce management platforms?
If the system provides an API, integration is possible. That said, some providers charge for API access. Even then, you can simply upload your sales data as an Excel or CSV file and get started right away — with or without an integration.
Are forecasts accurate even with little sales history?
Forecast accuracy improves the longer your sales history is. So the sooner you start managing with a statistical approach, the more your data builds up — forecasts keep getting sharper and your inventory operations get steadier over time. And above all, the biggest value is what you pick up along the way: which signals to watch and how to judge them — the management fundamentals — become second nature as you use Innostock. Even for a few SKUs or brand-new products, starting early pays off.
Will existing customers' rates go up too?
Not right away. This price adjustment applies to new customers, and if you are already subscribed, your current rate is maintained through December 31, 2026. From January 1, 2027, the updated rate applies, and we always notify you by email at least 30 days before any price change.
Can I cancel anytime?
Yes, you can cancel anytime.
What’s the difference between Solo and Team/Custom?
Solo is the standard plan for a single operator with up to 1,000 SKUs. If multiple people manage different brands, or you need large-scale/custom integration or security, that’s Team/Custom (contact us).
What is the onboarding fee?
A package covering initial data setup, a 1:1 onboarding session, and your first forecast review — we set it up with you so you get value fast. It’s currently free as a launch promotion.
