Workflow

Six inputs in. A defensible plan out.

The same five-scenario model an Amazon CFO would build by hand — except it stays in sync with your costs, your lead times, and your reorder calendar instead of going stale the moment you close the spreadsheet.

STEP 01

Drop in your six inputs

Landed cost, FBA fees, MOQ and lead times, ad budget, 3PL settings, and starting cash. Six numbered cards — only one open at a time, no spreadsheet maze.

1
Costs & Fees
Landed $8.10 · FBA $5.62
2
Order Sizing & Lead Time
2,400 pcs · 40 days
3
Marketing & Startup
Launch $4,500 · ROI 30%
STEP 02

Compare five scenarios at once

Realistic, PPC Heavy, Real-Optimistic, Optimistic, and a worst-case Clearance — each with its own 6-tier price ladder, growth curve, and TACOS. Edit one, watch them all re-rank.

Realistic$184k
PPC Heavy$152k
Optimistic$246k
STEP 03

Get the answer before you commit

Starting capital, break-even month, next reorder date, and the alerts that matter — cash low, override active, stockout risk — surfaced as plain English you can paste into a board update.

Tab · Data Entry

One numbered card at a time. No more spreadsheet maze.

Six grouped inputs replace the 40-cell sheet every Amazon operator dreads. Each card opens to a focused set of fields, validates as you type, and shows a one-line summary so you can see the whole model at a glance.

  • Costs, lead times, ads, cash, and inventory grouped semantically.
  • Per-cycle overrides for growth, TACOS, or pricing without breaking the baseline.
  • Every input is reversible — change one number and watch all five scenarios re-rank.

Tab · Inventory Journey

Watch every unit from factory floor to Amazon shelf.

A single chart that follows stock through manufacturing, sea transit, 3PL handoff, and FBA inbound — with safety-stock floors, reorder windows, and Chinese New Year alerts baked in.

  • Days of coverage, reorder point, and safety stock recalculated on every input change.
  • Q4 / CNY blackout periods highlighted so you order before the freight crunch.
  • Reorder cards with lead-time math — see exactly when to place the next PO.
Tab · Scenarios

Five plans side-by-side. Edit one, compare all.

Each scenario is its own pricing ladder, growth curve, and TACOS — but every tweak instantly re-ranks the others. So you can answer 'what if I go in cheap?' in the same view as 'what if PPC blows up?'

  • Six-tier price ladder per scenario — Month 1 uses Tier 1, Month 2 uses Tier 2, and so on.
  • Per-period overrides without breaking the baseline.
  • Cumulative cash balance plotted across all five scenarios on one chart.

  • Realistic column highlighted as the working baseline.
  • Variance vs Realistic shown per row — see where each scenario wins or loses.
  • PDF export keeps the comparison formatting intact for board updates.

The board-deck view — cumulative cash, accumulated profit, stock-over-time, and the three alerts that need your attention this week. Everything that mattered, condensed.

  • Year-1 revenue, net profit, break-even, and starting capital — at a glance.
  • Cost-of-sale stacked bar so you see where every dollar of revenue ends up.

Questions

What operators ask before their first plan.

Don't see your question? Reach out — every message gets read.

Talk to a human
Does this connect to Amazon to pull my real numbers?

Not yet. Cash & Stock Plan is a modeling tool — you bring the inputs (landed cost, fees, lead times, ad budget) and it builds the five scenarios. Live Amazon sync is on the roadmap.

How many scenarios can I model at once?

Five baseline scenarios per plan — Clearance, PPC Heavy, Realistic, Real-Optimistic, Optimistic — each with its own 6-tier pricing ladder. You can also clone a plan to model new product variants.

What lead time and safety-stock assumptions does it use?

Manufacturing, sea, and Amazon-inbound lead times are inputs you control. Safety stock is calculated from a service-level Z, lead-time SD, and demand SD — all visible in the Inventory tab.

Can I override growth or TACOS for a single month?

Yes — per-period overrides let you spike ad spend in M3 or trim growth in M5 without breaking the baseline. The Summary tab flags overrides with a purple alert.

Does the income statement support multi-year horizons?

Year toggle for 1, 2, or 3-year totals. Long-horizon planning is still in beta — verify the assumptions for year 2+ before sharing with investors.
