Free Calculators and Tools for Distributors

Practical calculators for the questions distributors actually ask. No signup, no email gate, no upsell. Use them, bookmark them, share them.

These tools answer specific operational and financial questions wholesale distributors face when evaluating performance or comparing software. Each is built around the same approach: enter a few numbers, get an immediate answer with relevant context. Built by a distribution-focused ERP vendor, but useful regardless of which ERP you run.

Inventory Turnover Calculator

Enter your COGS and average inventory to get your inventory turnover ratio, days inventory outstanding, and how your number compares to typical benchmarks for your category (food, hardware, HVAC, paper, auto parts, industrial supply).

QuickBooks Desktop → JSON Extractor (open source)

Free Python tool that exports a QuickBooks Desktop / Enterprise company file to JSON via the QB SDK. 15 entity types: customers, items, prices, vendors, invoices + lines, payments, AR. Compiles to a self-contained EXE so the customer's accountant doesn't need Python. Used in production on real client migrations including 60K+ invoice files. MIT licensed.

Why these tools exist

Distributors evaluating ERP, planning purchasing, or reviewing financial performance often need a quick answer to a specific question. Most of the calculators floating around the web are gated behind signup forms or buried inside vendor sales pages. These are not. The math is straightforward, the inputs match the way distributors actually track their numbers, and the output includes the context needed to act on it.

The QuickBooks extractor is in the same spirit. Most QuickBooks Desktop migrations hit the same wall — getting your data out cleanly, with relationships preserved, without paying $5K–$25K in consulting fees. We built the extractor for our own ERP migrations and open-sourced it because the destination ERP is where the real value is, not the data export.

If a calculator you'd find useful is missing, mention it via the contact form. Reorder point calculator, EDI onboarding cost estimator, and AR days-sales-outstanding tracker are next on the list.
