You've Been Thinking About This Product for Months. It's Time to Find Out If It's Real.
Maybe it's the side business you keep coming back to. You think about it all day and lie awake with it at night. You're ready to take the leap — you just need someone to show you the way.
So you open Amazon, browse suppliers and watch another video. You collect more ideas but still can't answer the questions that matter:
Are people actually buying?
What would make yours better?
Who can supply it?
What's left after the costs?
The fix
Idea to Inventory gives you an order to work in.
Every stage ends with something you can use.

A researched ideaDemand evidence with a GO, WATCH or PASS call

Look inside the course
Start with an idea. Use the data to improve it. Get it quoted.
Follow one headphone hook through every decision on Amazon US and Australia — then repeat the process with your own idea.
01Start with a product ideaNarrow down the comparable alternatives buyers already have.→ One idea to investigate
02Check demand signalsCompare prices, competitors and purchase badges. Record the gaps.→ A research record
03Use data to improve itTurn repeated review complaints into a specific change to test.→ An improvement brief
04Get supplier quotesSend one brief. Compare base vs improved, MOQs, samples, packaging.→ Quotes you can compare
05Check margin. Test a sample.Run your quotes through the Margin Calculator before any stock.→ Pursue, revise or pass

Step 5 · Quote → decisionCompare US$19.99 and US$18.99 with every example cost shown.GO, NO or HELD at each price
Proposed product changes are teaching examples; financial scenarios use illustrative inputs. Purchase badges are a lower-bound demand signal, not exact competitor sales.
Enter your per-unit costs, Amazon fees and selling price. See your profit and margin on every unit, and get a GO, NO or HELD result before you commit to stock.

Profit per unitUS$8.09 · 40.5%GO
Same product, lower price
At US$18.9938.4%NO
At US$14.9927.6%NO
A dollar off the price flips GO to NO. GO needs 40% or more before ads. Missing a required cost? The calculator returns HELD instead of guessing.

I'm Eli, co-founder of Bubzi Co and a top 1% global Amazon seller. Since 2014 I've researched products, worked with suppliers, bought stock, built listings and run ads — with my own business on the line.
Across 14 marketplaces, Bubzi Co grew to US$35M in cumulative brand sales and was named an AFR Fast Starter three years running (2018–2020).
I built this course so a complete beginner can understand the evidence and the numbers behind the early decisions.

The Amazon Brand Name Generator
Go from "I need a name" to three checked candidates in one sitting.
Tell it your product, which Amazon stores you're selling in (AU, USA or both), a few keywords and a style. It gives you 20 brand names. Each one comes with its style, why it works, and a rough read on how distinctive it is. Then it cuts the list to your top 3 with a scoring table.
It also runs the boring checks for you. It looks up .com and .com.au registration live, then hands you ready-made searches for the USPTO, IP Australia, Amazon US and Amazon AU, so you aren't typing every name into five different sites.
✓20 names in 9 styles, from Clean/friendly to Laboratory
✓Live .com and .com.au check (Codex, Claude, or ChatGPT with browsing)
✓One-click USPTO, IP Australia and Amazon searches
✓Top 3 shortlist with the scoring shown

Go through the material. If it doesn't help you take your next step, email eli@scalegloballywitheli.com within 60 days for a full course refund. Covers the $97 course; stock, samples and business costs are separate.
Start with Modules 1 and 2. Learn the budget and product checks, then research at least three ideas and choose one worth taking into the improvement and supplier steps.
Can I use this if I've never sold online?+
Yes. The course starts with how Amazon FBA works and follows a product through the early decisions, in order.
How much money do I need beyond the $97?+
Your product and marketplace determine the budget. The course helps you build a cash ceiling and gather quotes. Samples, stock, freight, testing, Amazon fees, advertising and software are separate. The $97 is the course price, not the cost to launch a business.
Do I need an Amazon seller account to begin?+
No. Research, improvement, supplier and number checks can start without one. Module 6 covers account setup so you can work on verification in parallel.
How quickly can I test a product?+
You can begin research, the brief and supplier requests as you work through the lessons. Suppliers control quote turnaround, sample production and shipping.
Do I need paid research software, Claude or ChatGPT?+
No. You can follow the core course with manual research and the Margin Calculator in your bonus Profit Kit. Claude and ChatGPT are optional ways to use the included AI bonus tools; follow the supplied setup guide. Any AI subscriptions or third-party software fees are separate from the course price.
What format is the course?+
Self-paced written lessons, illustrated PDFs, practical exercises and downloadable resources, including a fillable PDF workbook you can complete and save.
Will this teach full PPC or guarantee sales?+
It checks product economics and ad headroom before stock, rather than ongoing PPC management.
How does the 60-day refund work?+
Email eli@scalegloballywitheli.com within 60 days of purchase for a full course refund. See the policy above.
Do I get future updates?+
Yes. Updates while the course is offered are included as a bonus. You get course access and future updates to the course and included bonus tools at no extra cost.
Will the price go up?+
Yes. $97 is a strictly limited launch price. The price increases after launch. Launch members keep course access and every future update at the price they paid, even after the price increases.
