BenchStock knows the cost.
Materials inventory and true-cost for makers — what every product actually costs to make, what to charge, and never running out mid-order.
Stock, cost, plan.



What it really costs.
BenchStock is one loop, end to end. Add the materials you buy with their cost per unit. Build a product from those materials, and it shows you the true cost — materials, labor, and overhead — plus a suggested price. Then plan a run and get a shopping list of exactly what’s short.
A spreadsheet tells you what you paid last month. BenchStock answers the questions you have right now, at the bench:
- — What does this product actually cost to make?
- — What should I charge to hit the margin I want?
- — How many can I make with what I have on hand?
- — For this order, what do I need to buy — and from whom?
It’s a client-side PWA — no accounts, no backend. Every material, product, and count lives on your device, with a one-tap JSON backup whenever you want one.
BenchStock is the materials & true-cost piece of Bennett Studio — alongside MarginPrint, MarketDay, and MakerBooks. Every app shares the same local-first storage, backup, and offline foundations, so use BenchStock on its own or with the rest.

How is this different from Craftybase?+
Same core job — materials, true cost, inventory — but simpler, mobile-first, offline, and a fraction of the price. BenchStock is built for the maker who wants the answer, not an accounting course.
Where does my data live?+
On your device. BenchStock is a client-side app — no account, no server, no central database of your business to leak. Export a JSON backup anytime.
Do I need to be online?+
No. It runs entirely on your phone and works fully offline. Install it to your home screen and it behaves like a native app.
Can I import my spreadsheet?+
Yes — paste or upload a CSV of your materials (name, unit, cost, on-hand, supplier) and BenchStock maps the columns for you.
