Who This Is Built For
Whoever's Asking the Question, We Can Help
CFO / Finance Leader
"Our inventory valuation on the balance sheet hasn't matched reality in months. How do I trust these numbers again?"
We align your costing method and inventory system with your actual books, not just a software dashboard.
Warehouse Manager
"We're constantly stocking out on bestsellers and sitting on dead inventory. Why can't the system tell us this before it happens?"
Forecasting and reorder points get configured to your actual sales velocity, not left on default settings.
Owner / Decision-Maker
"We're evaluating Cin7 vs. Katana vs. just upgrading QuickBooks. Who tells us the truth instead of just selling us their platform?"
We're platform-agnostic and get paid the same either way — the recommendation is based on your business.
Inventory Manager
"I'm managing 2,000 SKUs across three warehouses in spreadsheets. How do I even start fixing this?"
We design the workflow first, then implement the system to match it; not the other way around.

Honest Fit Check
Is a Dedicated Inventory System Right for You?
Where it fits
A dedicated system is a strong fit if:
You're generating $10M+ annually with real inventory complexity
You're selling across multiple channels or locations
You have inventory tied to jobs, projects, or production batches
Spreadsheets or QuickBooks-only tracking are causing stockouts, overstock, or valuation errors
Where it doesn’t
It may be premature if:
You're under $1M in revenue with simple, low-SKU inventory — QuickBooks Online alone may still work
Your books aren't clean yet — inventory cleanup should come before new system implementation
You need physical warehousing or 3PL fulfillment — that's a different category of vendor than what we provide
