Shopify · Inventory & production planning

Sold out is a number.

Proso reads your Shopify store and prices every stock-out in lost revenue per week — worst first. Then it turns the answer into one decision per line: reorder or make this much, now. Every number is editable.

from the founder

We planned reorders and production runs for a D2C apparel brand in spreadsheets for years. Every Monday: export, pivot, squint, guess, order, hope. The guesses weren't the problem — the invisible cost of the sizes we'd already sold out of was.

Proso is that Monday, automated. It tells you what being sold out costs, suggests what to do about it, and gets out of the way when you know better.

Four clicks to your first order.

Proso never asks for anything Shopify already knows — not your currency, not your variants, not your suppliers. Install to first order in minutes, not months.

See the bleed

Your worst stock-out is the first row.

Every out-of-stock variant is losing revenue at your real run rate. Proso prices it per week, in your currency, and sorts the plan worst-first — so the first thing you see each morning is the most expensive problem you have.

"90-day run rate 5.7/day × (45d lead + 30d cover) − 12 on hand − 0 incoming" — the working, in one sentence, on every line
No black boxes

Every number is editable.

Forecasts are opinions. Yours wins. Proso shows its working in a plain sentence on every line, and if you know something the data doesn't — a collab drop, a supplier holiday — type over the number. It keeps your override and says so.

Ordering without ceremony

One click. Then Proso does the paperwork.

Mark a line Ordered and move on. Daily sync spots the stock landing, closes the order, and learns your real lead time from the cycle. Want proper purchase orders, suppliers, and a printable PDF? Turn on the PO module — it's there when you want it, never required.

And if you make what you sell

Production that's built in, not bolted on.

Most inventory apps stop at finished goods. Proso goes all the way down when you need it to: production runs, materials, and material gating — what you can make from what's on hand — built in, not bolted on. Buy everything? You'll never see any of it. Mixed? Set make-or-buy per product.

Coming from Stocky?

Stocky shut down on August 31, 2026. If your store just lost its planner, Proso is a Shopify-native home — for retailers who reorder and for the makers Stocky left stranded. Founding pricing applies.

Asked and answered.

I just reorder finished goods. Is Proso for me?
Yes — that's the default. The lost-revenue planner, one-click ordering, auto-receive, and learned lead times all work with nothing to set up. The production side exists only for stores that turn it on; you'll never see it.
How long does setup take?
Four clicks: install, answer one question, open the planner, place your first order. Proso reads everything else — currency, variants, vendors, sales history — from Shopify. There is no onboarding project, no CSV mapping, no implementation call.
Where do the suggestions come from?
Your own sales history, measured per in-stock day so sold-out weeks don't drag the forecast down. Every line shows its working in a plain sentence, and every number accepts a typed-over answer. Running on ad spend instead? Switch the demand model to budget × ROAS in Settings.
I don't know my lead times.
Nobody does at first. Proso assumes 45 days, labels it "assumed," and then learns your real lead times from actual order-to-delivery cycles. You can set or correct them anytime.
Does Proso change anything in my store?
No. Proso reads your catalog, orders, and inventory to build the plan. Your storefront, products, and prices are never touched. Orders you place in Proso live in Proso.
