Pay when the SKU has to survive the week.
What you are paying for is memory. The tooling curve, Factory A against Factory B, the price you told your co-founder — named, saved, and still on your account next Thursday. The math is free; the sheet that survives is the product.
Duty stays someone else’s job. Paste the stacked percent you already have. TrueUnit never invents an HTS code.
Pricing one product is a sprint, so the Product Pass is paid once and simply ends. The subscription is for consultants and operators who do this every month.
The worksheet never goes behind the paywall. The Product Pass never auto-renews — it ends, and your sheets stay readable. Checkout is by card via Stripe — use the same email you sign in with, and your account upgrades moments after. Cancel Workshop anytime (the link is in every Stripe receipt, or email support@trueunit.co) and your sheets export first.

They come here the moment they have two factory quotes, a mold bill, and a retail target. That is a product-development job. Freight companies do not want it. PLM tools are too much. The spreadsheet is what people use today, and it is usually wrong in three places.
