Why it works

The math a pro would run — done for you

Reorder points that fit your supplier

They account for lead time and demand swings — so you stop stocking out of your bestseller.

A buy-list that builds itself

See exactly what to order, how much, and the total cash you need — recalculated the moment your numbers change.

Find cash frozen in dead stock

Overstock flags surface the money sitting on your shelves in product that isn't moving.

How it works

Three steps. No spreadsheet degree required.

1

Drop in your products

Item, cost, supplier lead time, how fast it sells. Sample data is pre-loaded so you see it working first.

2

Par Level runs the math

Reorder points, safety stock, EOQ and ABC analysis calculate automatically — the moment you type.

3

Buy what the dashboard says

Open the dashboard, read the buy-list, place your orders. That's the whole job.

The other half of the job

Reordering right doesn't help if the price is wrong.

Most makers price on a feeling — double the material cost and call it done. Then labor and platform fees quietly eat the profit, and the "bestseller" turns out to lose money.

  • Your true unit cost, including the labor you forget to pay yourself
  • What Etsy, Shopify, Faire and wholesale really take — fees, processing and all
  • Real net margin on every product, after all of it
  • The exact price to hit your target margin, back-solved instead of guessed
  • The money you're leaving on the table each month, totaled

Get both systems together

The reorder system tells you to buy 120 units of wax. The pricing calculator tells you whether the candles you make from it are actually profitable. One without the other is half an answer.

Built by an operator who runs this math every morning — for fifteen years — before the platform even turns on.

Most "inventory templates" were built by someone who's never managed real stock. Par Level wasn't. It's the system a professional would build for themselves — not a ChatGPT screenshot.

Questions

Straight answers

Will it work in my spreadsheet app?

Yes — it's an .xlsx that opens in Microsoft Excel (365), Google Sheets, and Apple Numbers. The auto buy-list uses a dynamic formula best supported in Excel 365 or Google Sheets.

Do I need to be a spreadsheet expert?

No. You fill in a handful of input columns; everything else calculates on its own. There's a Start Here tab that walks you through setup in about five minutes.

What exactly do I get, and how?

An instant download, emailed the moment you check out. The Inventory & Reorder System is a six-tab workbook; the Pricing & Margin Calculator is a five-tab workbook. The Operator Bundle sends you both. Sample data is pre-loaded so you see them working before you swap in your own products.

Should I get one or both?

If you're stocking out or sitting on dead stock, start with the Inventory & Reorder System. If you're busy but somehow not making money, start with the Pricing & Margin Calculator. Most operators have both problems — the bundle is $59 instead of $78.

Is this for my kind of business?

If you buy stock and resell it — Etsy & Shopify sellers, makers, candle/soap/skincare, cafes, small retailers — yes. The math is the same whether you stock 10 SKUs or 500.

What's your refund policy?

Because it's an instant digital download, sales are final once delivered — but if the file won't open or something's genuinely broken, email support@parlevel.co and I'll fix it the same day.

Stop stocking out. Start pricing like a pro.

Both systems — real reorder-point and margin math, not a ChatGPT screenshot. Instant download.
