Supplement Business Manager — Complete Business Tracker for Small Supplement Sellers

A single, private, offline tool to run your entire supplement side hustle or small business — vendor pricing, inventory, sales, clients, and profit, all in one place.

Created by CURA Collective.

What it is

Supplement Business Manager is a self-contained business management app built specifically for people who buy supplements from multiple vendors and resell them — whether that's a small side hustle, a growing wholesale operation, or anything in between. No subscriptions, no monthly fees, no third-party servers holding your business data. It runs entirely on your own computer, and everything you enter stays yours.

You get one clean dashboard that answers the questions that actually matter day to day: What am I paying for this product right now? Who's my cheapest vendor? What's still in stock? What did I actually make on that last order?

What it does

• Compare vendor prices side by side — log prices from every supplier you buy from, including kit vs. individual-item pricing (e.g. a kit of 10), and instantly see who's cheapest per item.
• Track inventory by batch — receive stock under your own batch numbers, track quantity, cost, and both order date and received date. Low-stock and out-of-stock items are flagged automatically.
• Record every sale — log sales against the specific batch they came from, so your numbers are always tied to real cost, not estimates. Track payment method and customer per sale.
• See real profit, not guesses — profit and margin are calculated from what you actually paid for that exact batch, not just your list price. A separate "projected profit" view helps you decide who to order from next time.
• Track business expenses — packaging, shipping, marketing, fees — anything outside inventory cost, categorized and totaled.
• Build a shopping/reorder list — pull from products you've bought before or add new items, with the last known best price shown right on the list.
• Reward your regulars — mark specific customers as loyal and set a separate loyalty price per product; it auto-fills at checkout but stays fully editable.
• Brand it as your own — set your company name, logo, and accent color so it looks like your business, not a generic spreadsheet.
• Your data stays yours — saves directly to a file on your own computer. No account, no cloud storage, no one else has access to your numbers.

Who this is for

• Independent supplement resellers sourcing from multiple wholesalers
• Small distributors juggling several vendor price lists and want one clear comparison view
• Anyone currently tracking this in scattered notes, texts, or a messy spreadsheet who wants one real system
• Sellers who work with repeat clients and want to track loyalty pricing without guesswork
• Small teams who want a lightweight alternative to expensive inventory software they don't need

A few ways people use it

• Before placing a new order: open the price comparison view, see which vendor is cheapest per item this month (including kits vs. singles), and order from them instead of guessing from memory.
• After a sales weekend: log each sale against its batch, and immediately see real profit — not list-price math — for that weekend's activity.
• Monthly bookkeeping: check the dashboard for revenue, expenses, and net profit for the month in one glance, without pulling numbers from five different places.
• Restocking day: check the shopping list, see what's low, see the last price you paid, and place your order in minutes.
• Client management: mark your best repeat buyers as loyal customers, set their discounted rate once per product, and never have to remember or recalculate it again.
