Stop wasting time on spreadsheets.
Run your shop properly.
BUS Core is the free, local-first engine that runs your shop —
inventory, manufacturing, batches, recipes (BOM), and FIFO costing.
BUS Pro doesn’t change what Core does.
It just makes setup, updates, and day-to-day use easier.
You can run BUS Core forever without Pro.
Trial starts when you sign in. Cancel anytime. Core keeps running forever.
How it actually works
Simple enough to use today. Powerful enough to run production.
Receive Batches
Receive stock as batches with date + cost. Keep history and real cost basis instead of “one magic number” in a spreadsheet.
Define BOMs
Define recipes (BOM) once. Stop rebuilding the same job math over and over. Core knows what each build consumes.
Run & Track
Run builds that consume inputs and produce outputs. FIFO logic (First In, First Out) keeps costing defensible and prevents “why are margins weird?” chaos.
This replaces tribal memory.
You don’t need a $600/mo ERP to know what you have, what it costs, and what you can build. You need a system that keeps the numbers straight without babysitting.
Why upgrade to Pro?
Core does the manufacturing math. Pro is the layer that makes it painless to run daily: one-click launch, entitlement handling that doesn’t act like a hall monitor, and a workbench for purchasing/RFQ workflows.
-
Zero-config desktop launcher No terminals. No “localhost energy.” It opens like an app.
-
Entitlements that behave Checked at launch. Cached. No mid-session lockouts.
-
Pro Workbench (purchasing / RFQs) Dedicated workflow tools for the shop. Early access expands fast.
Core remains free forever. Pro is optional and never holds your data hostage.
BUS Core Pro
Start free for 14 days. Cancel anytime.
Download & Start TrialTrial starts when you sign in with your email (magic link). Pro checks entitlement at launch and can run offline using cached tokens (up to 7 days). Core remains fully usable without Pro.
That’s not software. That’s rent.
Predictable cost. Cancel anytime.
Cancel Pro → Core keeps running.
Try it like a tool, not a religion.
Download it. Run a real job through it. If Pro saves you time, keep it after the 14-day trial. If not — keep Core free forever.
