Scaling an Amazon business in 2025 means working smarter at every step. Competition is tight. Margins are thin. You need tools that cut wasted time and reduce mistakes. These 10 tips show real ways to source better, avoid risks, and manage orders without the usual headaches. Each tip ties to a feature in Seller Assistant, a platform built for wholesale and online arbitrage sellers. It connects browser extensions, bulk analyzers, and workflow tools into one system. No more switching between tabs or spreadsheets.
Seller Assistant handles product research, supplier outreach, purchase orders, and team notes in a single account. It works for FBA, FBM, dropshipping, private label, and wholesale. Whether you sell Amazon Basics or hunt deals in online arbitrage, these tips apply. I’ve used the platform daily for six months. The time saved is real. The mistakes avoided are measurable. Let’s get into the tips.
Tip 1: Turn Supplier Spreadsheets into Buy Lists – Automatically
The problem
You get a supplier price list with 5,000 SKUs. Most are junk. Some are restricted. A few could make money. Checking each row by hand takes hours. You open Keepa for sales rank. You check Seller Central for restrictions. You calculate fees in a separate sheet. You miss hazmat flags or IP risks. One bad buy hurts your metrics. I once ordered 100 units of a “safe” item. It was meltable. Amazon charged extra for storage. Profit gone.
The strategy
Upload the list once. Let software match SKUs to ASINs. Pull in sales rank, fees, and profit numbers. Filter for your targets. Export a clean buy list. You focus on decisions, not data entry.
What the tool does
Price List Analyzer in Seller Assistant reads Excel or CSV files. It connects supplier SKUs to Amazon data. You see profit, ROI, and risks for every line. Upload takes 10 seconds. Results come in under five minutes.
What it delivers:
- Auto ASIN matching for thousands of rows
- Sales estimates from BSR and 30/90/180-day history
- Full FBA fee breakdown – referral, storage, shipping, prep
- Profit calculator with your COG, prep, and shipping costs
- Filters for ROI, sales rank, hazmat, meltable, or fragile items
- Risk flags for generic brands, adult items, or missing FBA fees
- Notes that stick to ASINs for next time
- Saved filter views for repeat suppliers
- Export ready for purchase orders or Google Sheets
I uploaded a 3,000-line wholesale list last week. In four minutes, I had 87 items with 25%+ ROI and no restrictions. No manual VLOOKUP needed. I set filters for BSR under 10,000, ROI above 20%, and no hazmat. The tool removed 2,913 lines. I reviewed the rest in 15 minutes. I placed an order the same day.
For online arbitrage sellers, this works with retail spreadsheets too. Copy a Walmart or Target export. Paste into the analyzer. See which items beat Amazon’s Buy Box by 15% or more. I run this twice a week. It finds 20-30 deals per session.
Tip 2: Check Deals Fast Without Leaving Your Browser
The problem
You spot a possible deal on Amazon. You open Keepa in a new tab. Then a profit calculator. Then a restriction checker. Then IP Alert. Tabs pile up. You still miss hidden fees or competitor stock levels. By the time you decide, the price changes.
The strategy
Add data overlays to Amazon pages. See sales, profits, and risks on the same screen. No tab switching. No copy-paste.
What the tool does
Seller Assistant Browser Extension sits in Chrome. It shows key numbers on product pages, search results, and supplier sites. Install once. Log in. Data appears automatically.
What it delivers:
- Quick View on search pages – profit and sales rank in one glance
- Side panel on supplier sites – compare their price to Buy Box
- Profit calculator for FBA and FBM with real-time fees
- Restriction flags and IP alerts are built in
- Variation viewer to pick the best child ASIN
- Sales history charts powered by Keepa
- Stock checker for competitor inventory
- One-click export to Google Sheets
- Notes shared with your team
- Lookup links to eBay, Walmart, Target
I use Quick View every morning. I scan 50 search results in the time it used to take to open five tabs. I filter for sales above 30 units a month and profit above $5. The extension highlights winners in green. I add notes like “check supplier MOQ,” and they sync to my account.
For product sourcing in online arbitrage, I visit Walmart.com. The side panel shows Amazon’s current Buy Box. I see if I can buy at 60% of the Amazon price. I decide in 10 seconds per item.
Tip 3: Know If You Can Sell Before You Source
The problem
You spend two hours on a supplier list. You find 40 winners. You calculate profits. You reach out to the supplier. Then you learn that 30 are gated on your account. You need brand approval. Or category ungating. Time wasted. The supplier ignores your next email.
The strategy
Check eligibility in bulk before you dig deep. Remove dead ends early.
What the tool does
Bulk Restriction Checker takes a list of ASINs. It logs into your Seller Central and returns the approval status. No manual checks.
What it delivers:
- Eligible, Needs Approval, or Not Eligible for each ASIN
- Report in seconds for up to 20,000 ASINs
- Clean export to remove dead ends
- Works across marketplaces – US, UK, CA
I run every shortlist through this first. Last month, I had 1,200 ASINs from a toy wholesaler. 412 were gated. I removed them before contacting the supplier. I focused on the 788 I could list today. Approval rate on outreach went up 40%.
For private label sellers, use this before sourcing samples. Paste ASINs of similar products. See if the category is open. Avoid gated niches like groceries without approval.
Tip 4: Spot IP Risks Before You Buy Inventory
The problem
A product looks safe. Sales are steady. Profit looks good. You order 200 units. A week later, Amazon sends an IP complaint. Your listing is down. Money is tied up. You fight for weeks to resolve.
The strategy
Flag risky ASINs while you browse. Skip them before you spend.
What the tool does
IP Alert Extension adds a red triangle to listings with known complaints. It uses a database of policy violations.
What it delivers:
- Warning icon on Amazon pages and supplier sites
- Hover to see the complaint type and date
- Covers IP, authenticity, safety, and review issues
- Works with Quick View and Side Panel
- Syncs with restriction data
I skipped three deals last month because of late-night IP flags. One was a popular kitchen gadget. The complaint was from six months ago. Brand is still active. I moved on. Better safe than suspended.
For dropshipping, this saves returns. Customers complain about counterfeit products. You lose reviews. IP Alert catches these early.
Tip 5: Find U.S. Suppliers Without Google Rabbit Holes
The problem
You like an ASIN. Now you need a domestic wholesaler. You search Google. You get Alibaba links and dead sites. You email five suppliers. Two replies. One has an MOQ of 500. Hours gone.
The strategy
Ask AI to pull verified U.S. sources from the listing itself. Get links and prices fast.
What the tool does
Sourcing AI reads the product page. It returns up to 10 supplier offers. All U.S.-based.
What it delivers:
- U.S.-only results with price, MOQ, and link
- Exact or likely match labels
- Filters out offers above your max COG
- Runs from any Amazon page or search result
- Confidence score per match
I found a new snack supplier in 30 seconds. Price beat the current Buy Box by 18%. MOQ was 24 units. I ordered a test batch. Sold out in nine days.
For amazon online arbitrage, I use this on Walmart listings. I paste the URL into the extension. I get Amazon matches and supplier leads in one click.
Tip 6: Keep Supplier Contacts in One Place
The problem
You email 50 suppliers. Approvals trickle in. Details live in Gmail folders and sticky notes. You forgot who ships to which prep center. You resend the same tax form.
The strategy
Store every supplier in a shared database. Update once. Use everywhere.
What the tool does
The Suppliers Database holds contact info, status, and warehouse links. Your team sees the same data.
What it delivers:
- Profiles with name, site, contacts, and notes
- Status tags – New, Contacted, In Negotiation, Approved, Rejected
- Default warehouse per supplier
- Search and filter across all fields
- Auto-fill in purchase orders and price lists
- Team assignment per supplier
My VA adds new contacts daily. When I build a PO, the address is already there. No copy-paste. No wrong email.
For wholesalers for Amazon, tag suppliers by category. Filter for “pet supplies – approved”. Reach out only to open doors.
Tip 7: Route Inventory to the Right Warehouse Every Time
The problem
A supplier ships to the wrong prep center. Labels are off. Amazon rejects the shipment. You pay extra fees. You miss peak season.
The strategy
Link suppliers to warehouses once. Let the system handle routing.
What the tool does
Warehouse Database stores addresses and links them to suppliers. Data flows to every tool.
What it delivers:
- Full prep center and FBA warehouse details
- Auto routing in price lists and POs
- Option to override per order
- No copy-paste mistakes
- Multi-warehouse support
We run three prep centers. Routing errors dropped to zero after setup. One supplier sends to California. Another to Texas. The system knows.
For FBM sellers, route to your own warehouse. Track inbound shipments in the same place.
Tip 8: Build Purchase Orders Without Spreadsheet Chaos
The problem
You copy ASINs, quantities, and costs into a template. One typo and the supplier ships the wrong item. You catch it after payment.
The strategy
Create POs inside the same platform you use for research. Pull data automatically.
What the tool does
The Purchase Orders Module pulls data from shortlists and databases. Built in minutes.
What it delivers:
- Start from Price List Analyzer or manually
- Auto-fill supplier and warehouse fields
- Edit quantities and costs in real time
- Add tax and shipping estimates
- Export PDF or Excel for suppliers
- Track status – Draft, Sent, Completed, Canceled
- Error checks before export
I sent a clean 42-line PO in six minutes. Supplier confirmed the same day. No back-and-forth on SKUs.
For how to start online arbitrage, use this for small test orders. Start with 10 units. Scale when sales prove out.
Tip 9: Size Up Brands Before You Chase Them
The problem
You pick a hot brand. You spend weeks on outreach. You get approved. Then you see Amazon owns 80% of the Buy Box. No room for you. Inventory sits.
The strategy
Check brand metrics before you invest time. See revenue and competition first.
What the tool does
Brand Analyzer pulls catalog data for any brand name. One search. Full report.
What it delivers:
- Estimated monthly revenue across all ASINs
- Number of active listings
- Average FBA sellers per ASIN
- Buy Box share and pricing trends
- Review counts and average ratings
- Amazon in-stock rate
- Exportable report for deeper filters
I skipped two brands last quarter after seeing Amazon’s dominance. One had 92% Buy Box control. Saved dozens of outreach hours.
For product research, compare three brands side by side. Pick the one with an open Buy Box and steady sales.
Tip 10: Watch Competitor Catalogs Without Manual Checks
The problem
A rival adds a new ASIN. You notice weeks later. By then, they own the listing. You play catch-up.
The strategy
Track up to three competitor storefronts automatically. Get alerts on changes.
What the tool does
Seller Spy records adds, removes, and price changes. Runs in the background.
What it delivers:
- Daily catalog updates
- New ASIN alerts with profit potential
- Dropped items to avoid
- Price shift reports
- Excel export for analysis
- Brand-level insights
One competitor dropped a supplement line. I listed it the same week and took 60% of sales. They never came back.
For Amazon FBA business growth, track one big seller and one niche player. Copy winners. Avoid their flops.
FAQ
What products sell best on Amazon FBA?
Look for steady demand and low competition. Use a sales rank under 5,000 in a main category and fewer than eight FBA sellers. Check 90-day sales history. Avoid seasonal spikes unless you plan storage. Tools like Price List Analyzer show these fast. Focus on categories you understand. Home & Kitchen and Toys move year-round.
Can you still make money with Amazon FBA?
Yes. Pick the right products. Keep fees under 30%. Source at 3x ROI or better. Track metrics weekly. Reinvest profits into faster inventory turns. Many sellers hit six figures. Most quit because of poor sourcing. Use data, not guesses.
Is Amazon FBA good for beginners?
It handles shipping and customer service. Start with $1,000-$2,000. Buy 50 units of one product. Learn restrictions early. Use free Seller Central reports plus a tool like Seller Assistant. Read the help docs. Join a seller forum. Expect mistakes. Fix them fast.
Is Amazon FBA profitable in 2025?
Margins are tighter, but wholesale and online arbitrage still work. Focus on domestic sourcing and fast-moving inventory. Avoid gated categories without approval. Watch storage fees. Turn stock every 45 days. Profit comes from volume and speed.
Do you need $40 to sell on Amazon?
No. The individual plan is free, but it limits you to 40 items a month. The professional plan costs $39.99 and removes the cap. Upgrade when you list more than 40. Most serious sellers need a professional for bulk uploads and advertising.
Final Thoughts
These tips cover the full cycle – from supplier spreadsheets to competitor tracking. Each step connects in the Seller Assistant. You research in the browser. You check restrictions in bulk. You build POs without errors. Your team sees the same notes and data. You scale without chaos.
Amazon keeps changing rules. Fees rise. Competition grows. The sellers who win are the ones who remove manual work and catch risks early. Start with one tip. Try Price List Analyzer on your next supplier file. See the time saved. Add the browser extension next. Build from there.
I started with two tips. Now I use all ten. My sourcing time dropped 70%. Profits rose 35%. The platform pays for itself every month. Your results will vary. But the process works. Pick one area to fix. Improve it. Move to the next.
