If you're using more than two of these

You're already running an ERP - just one stitched together from PDFs and spreadsheets.

SimpleGrid is a custom ERP built around how your factory actually runs - all seven of these in one system, plus inventory, vendor history, customer history, and the analytics you actually want. One source of truth that updates itself in real time, instead of seven tabs and spreadsheets that never agree.

How private are these tools?

Very. The numbers you type and the files you upload never leave your browser - all calculation and PDF generation happens locally. We don't have a server-side database for any of this: no signup, no account, no cloud sync. Your vendor list and recent documents save to your browser's localStorage only. The one caveat: anonymous page analytics (which page you viewed, not what you typed) fire if you accept the cookie banner, and not otherwise.

Frequently asked questions

Do I need to sign up or pay?

No. Every tool here is free, browser-based, and requires no email or account.

Where do my numbers go?

Nowhere. Each tool runs entirely in your browser. Saved vendors, customer lists, and recent documents live in your browser's localStorage on your device. We have no server-side database for any of these tools.

Can I use these PDFs commercially with my customers?

Yes. The PDFs are watermark-free and yours to use. There's a small "Generated with SimpleGrid productive tools" line at the bottom - you can remove it by editing the PDF if you want.

What happens when I outgrow these tools?

You'll know. The moment you find yourself opening four of these tools to track one customer order, you're already running an ERP - just one stitched together. That's the moment SimpleGrid pays back. See how pricing works →

Where did all the other tools go?

We used to ship 140+ tools. We cut the catalog hard - then put back the ones earning their keep, ending at 35. The retired tools redirect here. If one of them was solving a real problem for you, email [email protected] and tell us which - if enough people ask for it, it comes back.

Each tool fixes one number. An ERP fixes the whole flow.

Every calculator here answers one question - your break-even, your OEE, your landed cost. A SimpleGrid ERP connects all of it into one live system modelled on how your floor runs: orders, inventory, costing, QC, contractors, dispatch, all updating themselves in real time. One smooth, integrated flow from PO to dispatch - no more spreadsheets that never agree.
