Eight variables, not just sales velocity

Most spreadsheet calculators only do sales / days. Restock Planner accounts for 2026 reality.

Sales velocity (rolling 90-day)Weighted by recency - last 30 days count more than days 60-90.
Supplier lead time + FBA inboundFrom PO to FBA receipt - including ocean/air freight + check-in time.
Chinese New Year shutdownDetects when CNY (Jan-Feb) hits your lead-time window - bumps reorder forward.
DD+7 cash flow timingModels when you'll have the cash to pay supplier deposit and balance - given Amazon's 7-day delivery+7 hold.
Q4 demand surgeAdjusts forecast upward for Prime Day, BFCM, Christmas - using your historical Q4 lift.
Aged storage breakevenCalculates the largest batch that won't trigger 12-month aged storage fees on leftover units.
Low-Inventory-Level fee thresholdKeeps you above the 28-day-supply line to avoid 2026's new hidden penalty.
MOQ & case-pack roundingSnaps batch size to your supplier's MOQ and case-pack increments - no awkward partials.

Common questions

Do I need to connect my Amazon account?
No. You only upload one CSV - the Business Report from Seller Central. No API connection, no credentials needed.
How accurate is the forecast?
Accuracy depends on sales-history stability. For products with 90+ days of consistent velocity, the model is within ±10% of actuals on a 60-day horizon. For new products or those with viral spikes, forecast confidence is lower - and the report flags those ASINs explicitly.
How often should I re-run it?
Quarterly is the sweet spot. Re-run before each major restock decision. You can also re-run if you launch a new product, change supplier, or notice a sales-velocity shift.
How is this different from Forecastly or SoStocked?
Forecastly and SoStocked are subscriptions ($79-89/mo) - you pay every month even if you only reorder twice a year. They also don't model DD+7 cash flow or Amazon's new Low-Inventory-Level fee. L-Guard charges $29 once, you re-run when needed, and RP factors in 2026 realities those tools haven't caught up to.
Does it work for new sellers with limited sales history?
It works best with 90+ days of sales data. For brand-new products, RP flags them as "low-confidence forecast" and gives a conservative recommendation based on category benchmarks instead.
