Mental Model

How BUS Core thinks

Understand this flow and everything makes sense.

Supplies → Blueprints → Products

Supplies = Raw materials you buy (fabric, thread, hardware)

Blueprints = Recipes that define what + how much

Products = Finished goods you make or sell

Costs flow forward. Inventory flows down. Nothing is automatic magic.

Getting Started

First-time setup

Do these in order. Takes 10 minutes.

1
Add your Supplies
Name, unit, cost, starting quantity
2
Create Blueprints
Choose supplies + quantities for each product
3
Build Products
Costs calculated automatically from blueprints
4
Manage Inventory
Stock in, consumption, corrections
Reality Check
BUS Core doesn't guess. If numbers look wrong, check your inputs.
Philosophy

Why local-first?

Your business data is too important to live in someone else's cloud.

🔒
Your data, your machine
Nothing transmitted. Ever. Full control of your business information.
💰
No recurring fees
Download once, use forever. No subscriptions, no per-user pricing.
⚡
Fast & reliable
Works offline. No internet needed. No downtime from cloud outages.
Current Limitations

This is beta software

  • • Single-machine only (no multi-user access yet)
  • • Manual backup & restore (no auto-sync)
  • • Database schema may change between versions
If something breaks:
  1. Export your data (if possible)
  2. Close BUS Core
  3. Delete local app data
  4. Restart and restore from export
Data Safety

Your data is safe

Local storage: All data lives in your machine's application data folder. Nothing is ever transmitted to external servers.

Password-protected exports: Backup your entire database as an encrypted file. Store it wherever you want.

Audit trail: Every operation is logged. See exactly what changed and when.
