Running an Amazon wholesale business means managing endless supplier lists, spreadsheets, and purchase orders. Seller Assistant brings structure to that chaos with a connected wholesale workflow that automates every step – from price list analysis to PO creation.

Instead of juggling tabs or manually checking ASINs, you can source products, verify restrictions, and send Amazon purchase orders in minutes. Whether you’re doing wholesale, or scaling online arbitrage or dropshipping, Seller Assistant acts as your all-in-one supplier sourcing software, helping you scale operations faster and smarter while maintaining full visibility and control over your Amazon business.

From Price List to Purchase Order: Wholesale Workflow

An Amazon wholesale workflow is a structured process that connects every step of your wholesale business – from finding profitable brands and verifying ASIN eligibility to sourcing suppliers, analyzing price lists, and sending purchase orders.

Instead of manually tracking products and orders across spreadsheets, a connected wholesale workflow keeps all data centralized, consistent, and automated. It helps sellers scale faster, avoid costly mistakes, and make data-driven buying decisions. For wholesale, online arbitrage, and dropshipping models, this workflow transforms scattered operations into a repeatable, efficient system that keeps you in full control.

Wholesale workflow steps

Step 1. Choose what to sell

Start by identifying brands and categories with consistent demand and strong profit margins. Study what successful sellers already carry, then evaluate those brands for sales history, catalog size, and competition level. Focus on data-backed brand choices before you begin sourcing.

Step 2. Check if you can sell it

Confirm that your Amazon account is eligible to sell the products you plan to source. Many brands and categories are gated or restricted, and verifying eligibility early prevents wasted time and inventory risks.

Step 3. Find suppliers

Locate verified wholesale suppliers who can offer your chosen brands at competitive prices. Use modern supplier sourcing software to skip outdated listings and quickly access trusted, resale-friendly distributors.

Step 4. Build your supplier database

Keep all supplier data organized in one central system. Tracking contacts, statuses, and terms ensures you never lose valuable leads and eliminates errors from juggling multiple spreadsheets.

Step 5. Assign warehouse

Assign default prep centers or warehouses to each supplier to automate shipping and routing. Centralized warehouse data ensures accuracy in addresses, fees, and delivery schedules.

Step 6. Analyze supplier price lists

Upload and scan supplier spreadsheets using price list analysis Amazon tools to find profitable products. Automation flags top opportunities while you verify details like ROI, restrictions, and demand.

Step 7. Create purchase orders

Turn shortlisted products into structured Amazon purchase orders in minutes. Automated PO creation reduces manual errors and keeps every cost, quantity, and routing detail consistent.

Step 8. Scale and stay in control

As your operation grows, delegate repetitive tasks to virtual assistants and connect your systems via integrations. Automation keeps your data synchronized and your workflow efficient, letting you scale confidently without losing visibility.

Inside the System: How Seller Assistant Automates Workflow

Every stage of your Amazon wholesale workflow – from product research to purchase order creation – is automated with Seller Assistant’s integrated tools. Each module connects seamlessly to the next, ensuring your data flows without friction.

You don’t need to switch between platforms, import files, or duplicate work. Below, we’ll walk through the entire flow tool by tool and show how each one powers a specific step of your wholesale process inside Seller Assistant.

Step 1. Choose profitable brands

Before launching into sourcing, the first step is deciding what to sell – and doing it with data, not guesswork. Unlike private label sellers, wholesale and online arbitrage sellers focus on existing Amazon listings, which means success depends on analyzing historical sales trends, brand size, and competition. The smartest approach is to look at what top-performing sellers already offer, study their brands, and identify opportunities based on numbers – not assumptions.

You want brands with a substantial product catalog (ideally 500+ ASINs), steady demand, and manageable competition. With the right insights, you can narrow your focus to products that have proven sales potential and sustainable profit margins long before you begin supplier outreach.

Tools that make it happen

How Seller Assistant tools help you

Storefront Widget

Integrates directly into Amazon storefront pages, automatically showing a seller’s profile details – including country, total ASINs, main brands, top categories, ratings, and reviews.
Displays product cards enriched with live metrics like estimated sales, BSR, price comparisons, FBA/FBM competition, and alerts for risks such as IP complaints or restrictions.
Lets you filter competitor listings by brand or category for quick, focused product research.

Seller Spy

Monitors competitor storefronts continuously, tracking what products they add or remove – with pricing details and direct ASIN links for easy access.
Highlights gaps and opportunities by comparing a competitor’s catalog with your own, helping you find potential product or brand leads.

Brand Analyzer

Helps determine whether a brand is worth pursuing as a supplier by revealing catalog size, sales potential, and overall profitability.
Shows key data like product count (preferably 500+ SKUs), estimated revenue, and competition levels.
Indicates Amazon’s share in the brand’s catalog – if Amazon sells more than 30% of its products, competition may be too high – and displays customer ratings and feedback for additional context.

How to apply the tools

Storefront Widget

Visit any competitor’s Amazon storefront – Storefront Widget automatically loads detailed analytics and product cards. Explore the store summary: competitor’s top categories, top-selling brands, and ASIN breakdowns. Additionally, research product by product: performance, risk levels, and other metrics to find high-demand, low-risk listings to target.

Seller Spy

In your Seller Assistant personal account, go to Seller Spy. Paste competitor storefront links into Seller Spy and let it track them daily. The tool logs added and removed products, giving you a live snapshot of what’s trending or being phased out. Use this data to anticipate market shifts before others do.

Brand Analyzer

In your Seller Assistant personal account, go to Brand Analyzer. Add a brand name to Brand Analyzer to see if it fits your wholesale criteria. Review its catalog size, profitability, and competition levels. Focus on brands that show high revenue potential with moderate competition, and flag them for supplier sourcing in the next step of your workflow.

Step 2. Verify your selling eligibility

Before investing time or money in a product or brand, you need to confirm that you’re allowed to sell it on your Amazon account. Many brands and categories are gated, meaning they require specific approvals – and some can’t be ungated at all, regardless of your experience or documentation. By checking restrictions upfront, you prevent wasted effort on deals that will never make it to your inventory.

Tool that makes it happen

Bulk Restriction Checker

How Seller Assistant tool helps you

Instantly checks selling eligibility for dozens – or even hundreds – of ASINs in one scan.
Clearly identify open, ready-to-sell items labeled as “Eligible”, meaning no approval is needed.
Flags products marked “Approval required”, showing where brand or category approval must be obtained.
Highlights permanently restricted ASINs as “Not eligible”, signaling that your account cannot sell them under any conditions.
Saves hours and avoids costly sourcing errors by verifying restrictions before moving forward with suppliers.

How to apply the tool

Log into your Seller Assistant workspace and open Bulk Restriction Checker. Select your target Amazon marketplace and upload your ASIN list. Within seconds, you’ll receive a detailed, color-coded report showing which items are eligible to sell, which need approval, and which should be excluded from your sourcing list altogether.

Step 3. Find wholesale suppliers

Once you’ve identified the right brands and products to sell, the next step is finding reliable suppliers who can offer them at profitable wholesale prices. Manual research is slow and often leads to outdated or low-quality sources. What you need is an automated, accurate, and verified way to discover U.S.-based wholesale suppliers that are open to resellers – without wasting hours scrolling through irrelevant directories or random websites.

Tool that makes it happen

Sourcing AI

How Seller Assistant tool helps you

With Sourcing AI, you can:

Run AI-powered searches to instantly find verified U.S. suppliers for specific products or brands.
Get up to 10 supplier offers per item, including pricing, SKUs, direct links, and minimum order quantities (MOQs).
Filter results by maximum cost of goods (COG) to instantly focus on profitable supplier options.
Compare Exact vs. Likely Matches to prioritize which suppliers to contact first.
Launch searches directly from Amazon product pages, search results, competitor storefronts, or supplier sites – all within one connected workflow.
Eliminate unreliable or outdated supplier sources and focus only on trusted, high-quality listings.

How to apply the tool

Open your Seller Assistant workspace. While browsing Amazon listings, search results, or storefronts, click the Sourcing AI button. Within seconds, you’ll receive a structured list a of a product’s U.S. suppliers showing prices, SKUs, links, and MOQs. Review, compare, and shortlist the most relevant offers – then proceed with supplier outreach directly from your workflow.

To look for brand suppliers, choose the request type: “Find Suppliers of XYZ brand in the US).”

Step 4. Create your supplier database

Once you begin contacting suppliers, organization becomes critical. In wholesale, most outreach attempts go unanswered – it’s common to get approved by only a few out of hundreds of prospects. That’s why supplier sourcing must be systematic and data-driven. Relying on scattered spreadsheets and email threads leads to confusion, lost opportunities, and duplicate work.

A centralized supplier database keeps every contact, status, and term in one place. It connects directly with your price lists, purchase orders, and warehouse settings, ensuring data stays synchronized and your workflow remains accurate and consistent at every step.

Tool that makes it happen

Suppliers Database

How Seller Assistant tool helps you

With Suppliers Database, you can:

Create comprehensive supplier profiles with details like company name, website, warehouse address, currency, and assigned team members.
Search, sort, and filter suppliers by name, location, status, or connected warehouse for quick navigation.
Assign relationship statuses such as New, Contacted, Negotiation, Approved, or Rejected to track your outreach progress.
Link suppliers to default warehouses or prep centers for faster, error-free purchase order creation.
Edit or update supplier details at any time – all linked data automatically stays consistent across other tools.
Access supplier information from modules like Price List Analyzer or Purchase Orders without re-entering it manually.

How to apply the tool

Open the Suppliers tab in your Seller Assistant account and click Add Supplier

In your Seller Assistant workspace, open the Suppliers section and click Add Supplier. Fill in the required fields – name and website – then add optional details such as contacts, warehouses, and assigned team members. Once saved, the supplier profile instantly becomes accessible throughout your workflow. When you later upload a price list or generate a purchase order, simply select that supplier, and all connected data – address, warehouse, and contact details – will auto-fill automatically.

Step 5. Assign warehouse for automatic routing

When managing multiple suppliers, you need an accurate and fast way to route orders to the correct prep center or warehouse. Tracking this manually in spreadsheets is time-consuming and risky – one wrong address or missing fee can lead to fulfillment delays or incorrect profit calculations.

With Seller Assistant’s Warehouse Database, all your prep centers and warehouse details are centralized. Each location’s contact data, shipping address, and status are stored in one place and linked directly to suppliers, ensuring every order is routed automatically and without errors.

Tool that makes it happen

Warehouses Database

How Seller Assistant tool helps you

With Warehouse Database, you can:

Store complete details for every prep center or warehouse – including addresses, contact info, and operational status – in one unified system.
Link suppliers to their default warehouses so that routing is handled automatically during price list analysis or purchase order creation.
Eliminate manual address entry, ensuring that every order goes to the correct location with consistent, validated data.

How to apply the tool

Open the Warehouse Database in your Seller Assistant account. Add each prep center or warehouse

Open the Warehouses Database in your Seller Assistant workspace. Add each prep center or warehouse with its exact shipping address, contact person, and any relevant notes. Then assign a default warehouse to every supplier. Once set, Seller Assistant will automatically apply these routing details during price list analysis and PO creation, keeping fulfillment organized and error-free.

Step 6. Scan supplier price lists for the best deals

To scale your Amazon wholesale business efficiently, you need to process large supplier price lists fast – identifying profitable, low-risk products without drowning in manual checks. Automation handles the heavy lifting, but each deal still needs verification to confirm it’s truly worth sourcing. This step helps eliminate false ASIN matches, overpriced listings, and hidden risks that can impact your margins.
