How should it get your sales and stock?

See what to restock, how much to buy and the latest order date.

One restock plan includes up to 100 stock items and 2 stock locations.

Your buyer approves purchases. The workflow cannot send supplier orders, pay invoices, move stock or change selling availability automatically.

What is included

Read your mapped sales, stock, incoming deliveries and buying rules. Draft quantities and order dates with calculations and unresolved inputs.

Supply mapped sales, available stock, reservations, incoming orders, supplier lead times, pack sizes and approved budgets. Include stockout periods and flat bundle mappings so demand is not counted twice. Complex manufacturing and new-product forecasts need separate scope.

Stores per plan: up to 1 store.

Forecast horizon: up to 90 days.

Sales history supplied: at least 365 days.

History in the starting dataset: up to 730 days.

How closely should it predict sales?

Choose a lower sales forecast error, then check buying quantities against your stock, lead times and budget.

How these standards are measured

Test future sales against a frozen seasonal baseline. Keep stockouts, missing history and new products visible; check every buying calculation against your approved rules.

Targets for your selected standard
What is checkedTarget
Forecast errorSum of absolute forecast errors divided by eligible observed sales on future holdouts. Lower is better. Report stockout treatment and zero-sales groups separately.≤30%
Improvement over baselineCompare both forecasts on identical future dates and item groups. Freeze a simple seasonal baseline before testing. A zero-error baseline cannot support a relative improvement claim.≥10%
Forecast biasAbsolute signed aggregate error divided by observed sales. Report over- and underprediction by product group too, so opposite errors do not cancel unnoticed.≤10%
Buying rules respectedCheck available stock, confirmed inbound, lead times, pack sizes, minimum quantities and budget. Flag infeasible or late plans instead of silently overriding rules.≥100%
Traceable quantitiesEach quantity and order date resolves to input versions and deterministic calculations. Explain bundle expansion, reservations and uncertain incoming stock.≥100%

These are proposed pilot targets, not measured results or a stockout guarantee. Sales during stockouts understate demand; your buyer reviews and approves purchasing.

How soon do you need the restock plan?

Choose how soon the draft should be ready after your inputs arrive.

Timing details

Time validation, local model fitting, forecasts, buying calculations, explanations and stored draft, including queues and retries. Initial historic backfill and human purchasing are separate.

The target applies to at least 95% of agreed test runs, with 2 in progress at a time.

How much do you want to spend per restock plan?

Choose your machine budget for forecasting stock needs and explaining the buying plan.

Cost details

Includes local forecasts, checked explanations, retries and shared hosting at the reference workload. Stock purchases, supplier charges, store subscriptions and buyer review are separate.

Reference machine cost: $0.35 – 0.65 per restock plan at 100 restock plans a month. The selected cap is a target to test, not a replacement for this estimate.

Where do you want it to run?

Run in your cloud or on your machine. Calculate forecasts and buying quantities locally; an approved model API can explain the checked results.

Data and access details

Runs under your account with local forecasting, restricted store access and an approval log.

Calculate forecasts and buying quantities locally. Send only approved aggregate plan context for checked explanations.

Send only approved aggregate stock and plan context for explanations, not customer identities or raw orders. Private mode uses local exports and templated explanations without a live store connection.

How do you want to use it?

Review the plan on a web page, ask your own agent or use a dedicated inventory agent.

Anything else your provider should know?

Optional. Your choices are included automatically.

Common questions

When should I subscribe to an existing product instead?

Use a hosted inventory planner if its forecasts, buying rules and integrations already fit. Buy a custom workflow for a missing process, private environment or interface that standard products cannot provide.

Will it place supplier orders for me?

It drafts quantities and order dates. Your buyer approves purchasing through your existing process; the starting workflow cannot send supplier orders, pay or move stock.

What if products are new or often out of stock?

Sales alone cannot reveal all lost demand. Your provider should agree a fallback and show uncertainty rather than pretend those products have a reliable forecast.

Does better forecasting guarantee fewer stockouts?

No. Stock accuracy, suppliers, purchasing budgets and how you use the plan also matter. Test availability and excess stock in a supervised live pilot.
