Sensible Forecasting vs Inventory Planner
Inventory Planner by Sage is powerful. It's also $249+/month and built for complex, multi-channel operations. Most small Shopify stores don't need that — and end up paying for features they never touch.
Side-by-side comparison.
Two very different tools for very different stages of business.
| Feature | Sensible Forecasting | Inventory Planner (Sage) |
|---|---|---|
| Price | $29/mo | ~$249/mo+ (custom quotes) |
| Free trial | 30 days, no credit card | None / custom demo |
| Forecasting method | Sales velocity based | Advanced seasonal + multi-channel |
| Purchase orders | No — CSV/Excel export | Yes, built-in PO creation |
| Channels | Shopify only | 30+ platforms |
| Reporting | Weekly email reports | Custom dashboards per team member |
| Setup time | ~5 minutes | Onboarding required |
| Best for | Small-medium Shopify stores that need simple reorder planning | Large multi-channel operations with complex forecasting needs |
When Inventory Planner is the right choice.
Inventory Planner is a serious tool backed by Sage, with over a decade of demand planning expertise. If you fit this profile, it's worth the investment.
$500K+ annual revenue
At this scale, the cost of stockouts and overstock dwarfs the subscription fee. Advanced forecasting pays for itself.
Multiple sales channels
Selling on Shopify, Amazon, eBay, wholesale, and more? You need a tool that unifies forecasting across all of them.
Team-specific reports
Buyers, managers, and executives each need different views? Inventory Planner builds custom dashboards per role.
Complex seasonal patterns
Heavy holiday spikes, fashion seasons, weather-dependent demand? You need algorithms that model seasonality properly.
Enterprise support needs
Dedicated account managers, custom onboarding, SLAs — the kind of support that comes with enterprise pricing.
When Sensible Forecasting is all you need.
Not every store needs a $249/month enterprise platform. If any of these sound familiar, Sensible Forecasting is probably the better fit.
A few hundred SKUs, a handful of suppliers, steady (not wildly seasonal) sales patterns.
No Amazon, no eBay, no wholesale portal. One channel, one store.
That's the core problem. Not custom dashboards, not multi-channel sync — just "what's running low and when do I need to order more?"
That's $3,000+ per year. If your margins are tight, that's a meaningful chunk of profit going to software.
Install in 5 minutes. Check your reorder list. Export for your supplier. Done.
The real question: do you actually need enterprise forecasting?
Many small store owners assume they need the most powerful tool available. It feels responsible — you don't want to cut corners on something as important as inventory. So you sign up for a $249/month platform with advanced seasonal algorithms, multi-channel sync, and custom dashboards for every team member.
Then three months later, you realize you're using about 10% of it. You're still just checking which products are running low and emailing your supplier a reorder list. The advanced features sit untouched. You're paying enterprise prices for a spreadsheet replacement.
Here's a simple test: if your main problem is "I keep running out of stock" or "I'm ordering too much" — and you sell on Shopify only — Sensible Forecasting solves that at 1/8th the price. No seasonal algorithms, no multi-channel sync, no custom dashboards. Just clear answers about what to reorder, when, and how much.
If you outgrow Sensible Forecasting later — if you expand to Amazon, start selling wholesale, or need team-specific reporting — Inventory Planner will be there. But start with what you actually need today.
Start with simple. Upgrade if you need to.
