Why selling on Amazon, Shopify, Walmart, TikTok, and eBay shouldn’t require five dashboards, twelve spreadsheets, and a stress ball.

If you're a modern eCommerce seller, chances are you’re juggling more platforms than a circus performer with a caffeine habit. Amazon? Of course. Shopify? Obviously. Walmart Marketplace? You bet. TikTok Shop? Absolutely - because apparently we’re all influencers now. eBay? Still kicking.

And through all this glorious chaos, you’re expected to know exactly what’s selling, what’s not, what needs restocking, what you’re actually earning, and which SKU is quietly draining your profits like a mischievous little gremlin.

Enter Indexos, your new best friend, digital therapist, and operational life-raft, all wrapped in a sleek platform designed specifically for multi-channel sellers. Let’s walk through the features you didn’t know you desperately needed but absolutely do.

1. Inventory Management That Doesn’t Require Black Magic

Gone are the days of guessing if SKU-143B is sitting in your warehouse, or sold out, or lost behind a pallet since 2021.

Indexos gives you unified inventory visibility across all your platforms. Real-time counts, smart alerts, and enough automations and replenishment plans to make your future self say, “Why didn’t I do this sooner?”

It’s like having inventory superpowers, minus the cape.

2. Sales Forecasting So Accurate It Feels Like You Aced Statistics Class

Most sellers forecast demand using a mix of spreadsheets, intuition, and maybe a bit of astronomy. Indexos, however, uses data-driven forecasting models that actually make sense.

We analyze your sales trends across Amazon, Shopify, Walmart, TikTok, eBay, and more so you can confidently:

  • Avoid stockouts
  • Prevent over-ordering
  • Plan for seasonality
  • Look incredibly smart in front of your team

It’s basically fortune-telling, but with your money instead of your love life.

3. Purchase Orders Without the Headache

If generating POs gives you the sweats, you’re not alone. With Indexos, creating purchase orders is fast, automated, and, dare we say, pleasant?

Our system suggests replenishment quantities based on real data (instead of vibes), links POs to products across all your sales channels, and keeps everything clean, traceable, and audit-friendly.

Your suppliers will think you suddenly became the most organized person they’ve ever met.

4. Real-Time COGS: Because You Deserve to Know What You’re Actually Making

Profit shouldn’t be a mystery. Indexos gives you instant, real-time cost of goods sold (COGS), accounting for changes in:

  • Unit cost
  • Shipping
  • Fees
  • Storage
  • Packaging
  • and the 37 other things sellers usually forget to include

No more “I think we’re profitable?” Now you’ll know. Your accountant will sleep better, too.

5. OCR Invoice Scanning: Your AI-Powered Paper Slayer

If you’ve ever manually typed an invoice into a spreadsheet, we know your pain. Indexos automates the entire process with OCR (Optical Character Recognition) so good, it could probably read your doctor’s handwriting.

Just upload your vendor invoice. 

1. We scan it

2. Extract all relevant data 

3. Match it to your purchase order 

4. And ensure your numbers are clean, consistent, and compliant. 

All without the need for data-entry interns (or stress crying).

6. Three-Way Matching That Would Make Any Auditor Proud

For those who didn’t know, three-way matching isn’t a Ménage à trois, it’s how serious businesses ensure they're paying for exactly what they received and ordered.

Indexos automatically cross-checks:

  1. Your Purchase Order
  2. Your Vendor Invoice
  3. Your Receiving Report

If anything doesn’t match, we flag it before it costs you money, sanity, or an awkward conversation with your supplier.

This is adulting at its finest.

7. Multi-Platform Data in ONE Place

The dream, right?

Instead of jumping between Amazon Seller Central, Shopify Admin, Walmart Seller Center, TikTok Seller Hub, and whatever eBay calls its dashboard this week, Indexos unifies it all.

Sales, fees, operations, inventory, profitability. One login. One dashboard. One place where your business finally makes sense. It’s like therapy for your data.

Why Multi-Platform Sellers Are Choosing Indexos

Because the alternative is:

  • spreadsheet chaos
  • unpredictable cash flow
  • surprise stockouts
  • manual invoice entry
  • “Where did my profits go?” syndrome

Indexos gives you clarity, control, automation, and a competitive edge, all while keeping things simple, intuitive, and even a little fun.

Ready to Feel Like You Actually Run Your Business?

If you're tired of juggling platforms and want a single system that handles forecasting, inventory, profits, POs, OCR, 3-way matching, and more

Indexos provides the operational insight and is the infrastructure layer your eCommerce business has been missing. And unlike your marketplace dashboards, we actually make sense.
