Cin7 Core is one of the better inventory systems for SMB e-commerce. It records movement, syncs with Shopify, prints purchase orders, and runs the warehouse. We've run our own 800-SKU Cin7 business on it for years.
But recording movement and telling you what to do about it are two different jobs. After 18 months of operating in Cin7 Core full-time, here are the four hidden costs we kept paying, and why we eventually built our own layer on top.
1. Reorder is reactive
Cin7's low-stock alerts fire when you cross a threshold you set manually. The threshold is usually wrong. Someone set it once and never touched it again, and it knows nothing about your lead times or your seasonality. By the time the alert fires you've already lost two days of sales, and the supplier you need is on a 28-day lead.
What you actually need is a forward-looking view that knows your lead times and projects when you'll cross zero. Not when you've crossed some line you picked 18 months ago.
Lost sales from preventable stock-outs. For a $3M/yr e-commerce business, even 1% of revenue lost to stock-outs is $30,000.
2. Seasonality is invisible
Cin7's reorder logic uses a flat trailing average. It doesn't know that you sell three times your normal volume in December, or that Mother's Day moves 40% of your candles. It certainly doesn't know that your Father's Day mug supplier needs 60 days, not 30, in the lead-up.
So you stock out on the products that matter most, in the windows that matter most. Same thing happens every year.
Your highest-margin sales are the ones you miss. And you've already paid Google and Meta to drive the traffic by the time the customer hits the empty product page.
3. Slow-movers pile up silently
Cin7 doesn't flag SKUs that haven't sold in 90 or 180 days. They sit on shelves, eating cash and warehouse space. The first time anyone notices is at the year-end stock take, when they show up as a writedown.
Working capital tied up on a shelf, plus the warehouse rent it sits in, plus whatever you eventually lose clearing it at a discount. Conservative estimate: 8–12% of inventory value, if you've never tackled it.
4. Margin is a guess
Cin7 shows you DEAR unit cost. Real margin needs landed cost: unit + labor + raw materials (where you cut from sheets) + inbound freight. Without that, you can sell loss-makers for months without realizing.
We had four products we'd been selling at a 6% loss for nine months before we caught them. That's $84,000 left on the table.
Whatever your worst loss-makers are, multiplied by however long it takes you to find them.
What to do about it
Those four costs are why we built Stocura. It sits on top of Cin7 Core, leaves your Cin7 setup alone, and gives you the layer Cin7 doesn't:
- Forward-looking reorder with seasonal-aware reorder points and one-click draft POs straight back to Cin7
- Per-SKU seasonality detection across 24 months of history, not flat averages
- Slow-mover surfacing with a decision workflow: discount, bundle, or discontinue
- True landed-cost margin that includes labor and raw materials, not just DEAR unit cost
Stocura is in beta and free during beta. Connect your Cin7 Core and the first reorder queue is ready by the next morning. Start with cost three. Pull the slow-movers and you'll usually find the money to justify the whole exercise in a week.
