How Seller 365 supports the entire seller journey

Running an Amazon business means juggling a pile of tools, logins, and subscriptions. Most sellers end up cobbling together separate apps: one for sourcing, another for inventory, a third for pricing, and a fourth for tracking profits. That patchwork creates real headaches. It wastes money, and it makes it nearly impossible to get one clear picture of how your business is actually doing.

Seller 365 fixes that by putting every essential seller tool into one affordable bundle, and it just got a major upgrade. Here’s how Seller 365 supports you at every stage of the selling process, from sourcing your first product to getting back money you’re owed.

The five stages of a profitable Amazon business

Every successful Amazon business moves through the same basic stages. You source profitable products, prep and ship them to Amazon, win sales through smart pricing and customer engagement, track your true profit, and recover money Amazon owes you when things go wrong. That last part is new territory for most sellers, and we’ll get to it.

Sellers who piece together separate apps for each stage run into the same problems over and over. Jumping between platforms eats up hours that should go toward growing the business. Every new interface adds its own learning curve. And the real cost is that your data gets stuck in separate silos, so you never get one clean view of how your business is doing.

Seller 365 solves this by bringing every stage into one platform, under one login.

Stage 1: Finding profitable products to sell

Everything starts with finding products worth selling. Seller 365 includes four sourcing tools, and each one is built for a different sourcing strategy.

Tactical Arbitrage scans over 1,400 retail websites for online arbitrage opportunities. It compares prices against Amazon and calculates potential profit after fees, and it can search whole categories or wholesale catalogs at once. You can even set up Quick Picks to get pre-analyzed opportunities sent your way.

ScoutIQ handles book sourcing with barcode scanning and instant profitability checks. Instead of guessing what will sell, you see actual sales velocity, competition, and profit potential on the spot. The downloadable database works offline, too, so thrift stores and library sales are fair game even without signal.

ScoutX layers real-time data directly onto Amazon product pages, so you’re not tab-switching every time you want a number. Around 60 data points show up right where you’re already looking.

Scoutify is built for retail arbitrage. Scan a barcode in-store and see instantly whether an item is profitable, restricted, or too slow-moving to bother with. It’ll also flag products that match your buying criteria automatically.

These four tools cover online sourcing, retail runs, and book flipping. Pick whichever combination matches how you actually source.

Stage 2: Prepping and shipping inventory to Amazon

Once you’ve found the product, you need it in Amazon’s warehouse correctly and on time. That’s InventoryLab’s job.

InventoryLab handles the entire listing and shipping process. Create listings in bulk, print every required label, and generate Amazon-compliant shipments in minutes, with the system walking you through each step so costly mistakes don’t slip through and delay your inventory.

It also catches prep issues before Amazon does. InventoryLab automatically flags items that need special handling or hazmat designation, so you know which products need poly bags, suffocation warning labels, or other required prep before a shipment gets rejected at the door.

For products sourced through Scoutify or ScoutX, the buy list syncs straight into InventoryLab. No manual re-entry, no cost tracking errors from the moment you make a purchase. Our full walkthrough on FBA prep with InventoryLab covers the workflow in more detail.

Box content tracking, shipment planning, and label generation all run together, so shipping 500 units takes about as much effort as shipping five. Faster prep means your inventory reaches Amazon sooner, which means faster sales.

Stage 3: Winning sales and protecting your listings

Getting inventory to Amazon is only half the job. To actually make money, you need competitive pricing, steady reviews, and listings that stay protected. Seller 365 covers all three.

SmartRepricer adjusts your prices automatically across 22 Amazon marketplaces based on competitor moves, inventory levels, and market conditions. You set the strategy: custom pricing rules, profit guards that stop you from selling below margin, and AI-driven logic that maximizes your Buy Box time. Once it’s set up, you’re not sitting there manually checking prices all day.

FeedbackWhiz Emails automates review and feedback requests while staying inside Amazon’s rules. You can either automate Amazon’s built-in “request a review” button or send your own personalized templates, timed precisely and routed to the right customers, without risking a policy violation.

FeedbackWhiz Alerts protects the listings you’ve already built. It flags Buy Box losses, listing suppressions, and reviews that need a response, and it monitors for unauthorized changes to your listings. AI-generated sentiment summaries give you a quick read on how customers actually feel, without digging through every review yourself.

Together, these three tools keep your prices sharp and your listings intact while you focus on the next product to source.

Stage 4: Tracking your true profit

Knowing your real profitability, not just your revenue, is what separates sellers who scale from sellers who stall. Seller 365 includes two tools for this.

FeedbackWhiz Profits gives you a clear view of performance across 21 Amazon marketplaces and Walmart. Track revenue, costs, and profit at the SKU level, with customizable expense categories and visualizations that show you exactly which products and channels are actually making money.

InventoryLab Accounting delivers tax-ready financial data by capturing costs as you list, tracking every Amazon fee and adjustment, and sorting it all into categories that make tax season far less painful. Because it’s tied into InventoryLab’s listing workflow, every expense gets recorded accurately from the moment you buy.

Between the two, you get both a real-time view of profitability and a clean paper trail for taxes.

Stage 5: Recovering money Amazon owes you

Here’s the part that’s new. FBA sellers lose money to Amazon errors more often than most realize: lost inventory, incorrect fees, botched return processing, shipment discrepancies. Individually, each one looks small. Add them up over a year, and they take a real bite out of your margin.

Seller 365 Reimbursements is now included on every Seller 365 plan tier. It continuously audits your account, identifies eligible claims, and files them on your behalf, with specialists handling the complex cases that automated tools tend to miss. You don’t pay anything upfront. Commission runs 15% of recovered amounts on the Standard and Teams tiers, and 5% on Pro, and you’re only charged when a claim actually gets paid out.

Find it directly in your Threecolts Hub. If you want the full rundown, here’s how FBA reimbursements work with Seller 365.

Why one subscription beats five

You might be thinking your current setup works fine. Plenty of sellers feel that way right up until they add up what it’s actually costing them.

A typical fragmented stack runs sourcing tools at $100 or more, inventory management around $50 to $60, repricing near $90 to $100, and feedback or financial tracking tools at another $50 or so. Add it up, and you land close to $319 a month for the basics, before Amazon reimbursements are even part of the picture. Seller 365 starts at $69/month and now includes reimbursement recovery on top of the same 10 tools.

Getting started with Seller 365

Switching to an all-in-one platform sounds like a bigger project than it is. Seller 365 plans start at $69/month and include all 10 apps covering sourcing, prep, pricing, feedback, and profit tracking, plus reimbursements on every tier. Higher tiers add more users, priority support, and other perks as your business grows. If you’re getting close to outgrowing the base plan, here’s when it makes sense to upgrade to Seller 365 Pro.

Every plan comes with a 14-day free trial: 7 days instantly, plus 7 more once you connect your Amazon account.

One login means one place to check instead of five browser tabs and a password manager that’s stopped making sense. When you’re getting started, don’t try to implement everything at once. Most sellers start with the sourcing tools, then layer in shipping, pricing, and financial tracking as they get comfortable. For a step-by-step approach, our Seller 365 best practices guide is a good next stop.
