Restock planning
Restock for profit, not just volume.
- Why each product is bought, or left out
- Seasons, Subscribe & Save and lead times included
- Your rules: always buy, never buy, prioritise
Amazon's restock recommendation is built to keep you in stock, from your sales history. But Amazon can't see what you actually pay your suppliers, your payment terms or the cash you have. EC THUNDER plans with all of it, so the same budget goes first to the products that leave the most profit. Amazon's recommendation is costed the same way and kept beside it, so you can compare and adjust either one at any time.
Request early accessBuy ¥100 of stock. Once it sells and Amazon's fees and freight to FBA are paid, this is what your ¥100 comes back as.
- Buy ¥100 of stock
- It sells on Amazon
- Paid out after fees and freight
- Your ¥100 comes back as ¥147.5
Measured on our own account, October 2026: same budget, both plans costed the same way.

Starts from the money you actually have
- Credit lines and payment terms per supplier
- Filter suppliers by how you can pay
- Split one plan into credit and cash orders
Planning begins with your supplier's credit line: what's unpaid, what's delivered and waiting for a statement, and what's left. Add cash on delivery or money paid in advance, or plan without a limit.
- Unpaid statements29%
- Delivered, awaiting statement47%
- Available to plan24%
Buys what earns the most per yen
- Whole cases, never over budget
- Seasonal peaks and Subscribe & Save included
- Your own warehouse stock used first
Every product's demand, stock at Amazon, inbound units, season and real unit profit go into one score. Cover is bought a week at a time, so every product that sells gets its floor before any one product gets depth.
Amazon's plan, always beside yours
- Expected profit for both plans
- Products left out, with the reason
- Always buy / never buy set by your rules
Amazon's restock recommendation is costed exactly like ours and cut to the same budget in Amazon's own order of urgency. Switch between our plan, Amazon's and a side-by-side view at any time, and adjust any line before you order.
Straight to a purchase order
- Order emails to suppliers
- Changes recorded
- Invoices imported and matched to the end
Tick the lines you want, choose how the order will be paid and draft it. The order carries your supplier's terms and can be emailed from the app, and it becomes the prep sheet when the goods arrive.
