Running a profitable Amazon FBA business requires software. Sourcing tools to find profitable products. Inventory management to prep and ship efficiently. A repricer to stay competitive. Accounting to track actual margins. Feedback automation to protect your seller rating. Bought separately, these tools cost $300+ per month. Threecolts bundles all of them into one subscription for $69/month.
This isn’t some watered-down “bundle” where you get limited versions of tools nobody uses. Threecolts acquired several of the most established Amazon seller tools in the market – Tactical Arbitrage, InventoryLab, FeedbackWhiz, SmartRepricer, ScoutIQ – and consolidated them into a single product called Seller 365. The tools are the originals. The functionality is the same. The price is just dramatically lower because you’re buying them as a bundle rather than separately.
Seller 365 is used by 30,000+ active sellers across Amazon, Walmart, and eBay. It holds a 4.8/5 on G2 and 4.4/5 on Trustpilot. This is an independent review covering the 10 tools included, the three standard pricing plans, what makes Seller 365 genuinely different from competing bundles, who it’s right for, and who should look elsewhere.

What Is Threecolts?
Threecolts is an e-commerce software company that acquired multiple established Amazon seller tools and consolidated them into a single subscription product: Seller 365. Instead of subscribing to 5-7 platforms separately, you pay one flat fee and access all of them through the Threecolts Hub – a unified launcher dashboard. One login. One billing cycle. One support team.
The tools inside Seller 365 aren’t new builds. They’re the same software that tens of thousands of Amazon sellers were paying for individually: InventoryLab (previously $69/month standalone), Tactical Arbitrage (previously $89-97/month standalone), FeedbackWhiz – all the originals, bundled together.
The 10 Tools in Seller 365
1. Tactical Arbitrage: The headline tool for online arbitrage sellers. Scans 1,000+ online retailers automatically and identifies products you can buy at retail prices and resell profitably on Amazon. Set searches before bed, wake up to hundreds of analyzed sourcing opportunities ranked by ROI. Previously $89-97/month standalone.
2. InventoryLab: The operational engine for FBA sellers. Create listings, build shipment plans, manage inventory prep, print labels, and push boxes to Amazon fulfillment centers – all in one continuous workflow. Previously $69/month standalone; tens of thousands used this tool alone.
3. SmartRepricer: Automated repricing across 22 Amazon marketplaces using customizable rule-based logic. Integrates directly with InventoryLab and pulls your actual product costs and fees, so every pricing decision is based on real margin data, not estimates.
4. ScoutIQ: Book scouting and scanning app for offline retail sourcing. Built specifically for book resellers – scan barcodes at thrift stores, library sales, and used book shops. Works offline for areas with unreliable cell service.
5. Scoutify: Mobile retail scanning app for general retail arbitrage. Scan product barcodes in physical retail stores to instantly see Amazon sales rank, current prices, competition, and estimated profit.
6. ScoutX: Browser extension for instant product research during online sourcing. Overlays Amazon data directly on retailer websites as you browse.
7. InventoryLab Accounting: Real-time tracking of 30+ Amazon fee types – FBA fees, cost of goods sold, merchant-fulfilled costs, international charges. No manual reconciliation. No spreadsheets.
8. FeedbackWhiz Profits: A visual financial dashboard aggregating revenue, advertising costs, and net profit. Designed as a higher-level overview that pairs with InventoryLab Accounting.
9. FeedbackWhiz Emails: Automated review request campaigns with precise targeting rules. Focus review requests on repeat buyers or high-satisfaction orders specifically – improving response rates while staying within Amazon’s terms of service.
10. FeedbackWhiz Alerts: 24/7 listing monitoring with instant notifications for 13+ critical events: Buy Box losses, hijacker activity, listing suppression, title changes, image removals, price changes, and more.
Pricing
Seller 365 – $69/month (single user): All 10 tools, one login. Standard usage limits (5,000 listings on some tools). 14-day free trial (7 days instantly + 7 more when you connect your Amazon or Walmart seller account). Standard support and Threecolts University access.
Seller 365 Teams – $79/month or ~$898/year (annual saves $50): Everything in Seller 365, plus up to 10 users (add up to 9 team members, VAs, or business partners). Annual billing saves $50 compared to $948/year at monthly rates.
Seller 365 Pro (pricing on request, includes free reimbursements): Everything in Teams, plus commission-free FBA reimbursements (Threecolts’ team actively scans your account for 30+ error types, files claims on your behalf, and keeps 0% of recovered funds). Priority support with 30-minute response times. Annual billing saves $200/year. Most third-party reimbursement services charge 15-25% of recovered funds – Threecolts keeps nothing. Threecolts states most reimbursements exceed $199.
Enterprise Plans (Margin Pro and Multichannel Pro – custom pricing): For $1M+ revenue sellers or multichannel operations at scale. Contact Threecolts sales.
The value math: Buying just five of the ten included tools separately at rough standalone rates would cost approximately $230/month ($2,760/year). Seller 365 at $69/month saves approximately $162/month or $1,944/year on those five tools alone. Note: Threecolts locks current pricing for the life of your subscription even if prices rise later.

The Threecolts Hub
One practical improvement Seller 365 made over subscribing to each tool separately: the Threecolts Hub. A single dashboard where all 10 tools are accessible with one click. No separate logins, no tab management, no duplicate passwords. Notifications from all tools appear in one unified notification center. Managing six separate platforms creates real mental overhead – constantly relearning different interfaces, different support contacts, different billing dates. The Hub consolidates that into one system.
Threecolts for Amazon FBA Sellers
Online arbitrage at scale: For sellers doing online arbitrage on Amazon, Tactical Arbitrage is the core tool. It automates the sourcing process that used to require manually checking hundreds of websites for price disparities. Searches run overnight and surface ranked opportunities by ROI. This was previously only affordable to higher-volume sellers at $89-97/month.
FBA shipment efficiency: InventoryLab handles the operational piece – listing, prep, labeling, and shipping – that most newer sellers manage across multiple disconnected tools and spreadsheets. Streamlining this into one workflow reduces prep center errors and accelerates how quickly inventory reaches Amazon fulfillment.
Business formation and financial clarity: InventoryLab Accounting and FeedbackWhiz Profits together provide the financial visibility that serious Amazon businesses need – tracking fees, COGS, and actual margins across 30+ Amazon fee types in real time. This data is essential for proper bookkeeping, tax prep, and business growth decisions.
Listing protection: For ecommerce businesses managing significant Amazon inventory, FeedbackWhiz Alerts provides 24/7 monitoring that catches hijackers, Buy Box losses, and listing suppressions immediately rather than hours or days later when damage has already accumulated.
What Real Users Say
According to G2’s verified Threecolts Seller 365 reviews (4.8/5 rating), users consistently highlight three themes: the platform’s responsiveness to feature requests (one reviewer notes a requested feature was added within two weeks), the quality of onboarding support and weekly live coaching sessions, and the operational efficiency of having multiple tools under one login. One G2 reviewer specifically notes going from “logging into 4 different vendors to one website which made life a ton easier.” The most cited friction: waiting on features in development and the initial complexity of activating multiple tools simultaneously.
According to Capterra’s verified Threecolts reviews, the platform is described as a cutting-edge e-commerce software suite serving 20,000+ businesses. Users praise the comprehensive coverage of key Amazon seller operations – sourcing, shipping, pricing, feedback, reimbursements – without needing to evaluate and manage relationships with multiple separate vendors.
According to The Selling Guys’ independent Seller 365 review (James, 15 years of Amazon selling experience, $10M+ in sales), Seller 365 is described as “one of the most comprehensive Amazon seller tools currently available.” The cost savings are obvious, but the reviewer emphasizes the real value is integration: data flows between tools without manual exports or duplicate entry. Recommendation: sellers moving $20K+ monthly or managing 1,000+ SKUs should consider upgrading to Pro for automated reimbursements and higher usage limits.
Pros and Cons
What I like about Threecolts Seller 365:
The value math is genuinely compelling. Getting Tactical Arbitrage ($89/month), InventoryLab ($69/month), FeedbackWhiz, SmartRepricer, and Scoutify individually would cost significantly more than $69/month. These aren’t watered-down versions – they’re the same tools sellers were buying separately.
Commission-free reimbursements on Pro is a category standout. Most third-party Amazon reimbursement services charge 15-25% of recovered funds. Threecolts keeps zero percent. For sellers with significant Amazon volume, recovered funds from lost inventory and overcharged fees can easily exceed the plan cost.
Threecolts University is a structured educational platform covering every tool – actual training courses, not just documentation. Reduces the learning curve significantly.
Unified support team that understands your entire workflow. One team, full context on your operation.
Current pricing is locked for the life of your subscription – even if Threecolts raises prices later.
4.8/5 on G2 from real users. Works across Amazon, Walmart, and eBay – not Amazon-only.
What I’d flag:
Occasional performance lag during peak usage periods. Multiple users report this specifically during high-demand Tactical Arbitrage sourcing scans. Not a data accuracy issue – just slower than ideal.
Not the right fit for private label sellers. If your primary needs are keyword research, listing optimization, and PPC campaign management, Helium 10 or Jungle Scout serve those use cases better.
The base Seller 365 plan is limited to a single user. If you work with VAs or business partners, you need the Teams plan at $79/month.
Ten tools can overwhelm new sellers. Recommended approach: activate and master one tool per week, starting with sourcing, then operations, then repricing, then automation. The 14-day trial gives enough time to evaluate your most important use case.
Some tools have usage limits on the base plan (5,000 listings). High-volume sellers managing large catalogs need Pro for uncapped limits.
Threecolts vs Alternatives
| Platform | Price | Tools Included | Best For | Reimbursements |
|---|---|---|---|---|
| Threecolts Seller 365 | $69/mo | 10 (sourcing through accounting) | Arbitrage/FBA resellers | Commission-free (Pro) |
| Helium 10 | $99-$279/mo | Research, PPC, listing | Private label sellers | Not included |
| Jungle Scout | $49-$129/mo | Research, analytics | Private label sellers | Not included |
| InventoryLab (standalone) | $69/mo | 1 (inventory + accounting) | FBA operations only | Not included |
| Tactical Arbitrage (standalone) | $89-97/mo | 1 (sourcing only) | Online arbitrage only | Not included |
Threecolts Seller 365 competes most directly with the combination of Tactical Arbitrage + InventoryLab as a standalone pair – approximately $158/month. Seller 365 includes those two plus eight more tools for $69/month. For private label sellers needing keyword research and PPC tooling, Helium 10 or Jungle Scout remain the stronger options.

What does Tactical Arbitrage do?
Tactical Arbitrage is an online arbitrage sourcing tool that automatically scans 1,000+ online retailers and identifies products with profitable price disparities – items you can buy at retail prices and resell profitably on Amazon FBA. Set up searches to run overnight and review ranked opportunities by ROI. Previously $89-97/month as a standalone subscription; now included in Seller 365 at $69/month.
What is the commission-free reimbursement on Seller 365 Pro?
On the Pro plan, Threecolts’ team actively audits your Amazon Seller Central account for 30+ types of Amazon errors entitling you to reimbursement: lost inventory, damaged goods, overcharged FBA fees, unreturned items, and more. They file claims on your behalf and recover funds directly to your account, keeping 0% of what they recover. Most third-party Amazon reimbursement services charge 15-25% of recovered funds. For sellers with significant Amazon volume, recovered funds often exceed the Pro plan’s cost.
Is Threecolts good for private label sellers?
Not primarily. Seller 365’s toolset is built for arbitrage sellers and FBA resellers. The sourcing tools are retail/online arbitrage-focused. For private label sellers whose primary needs are keyword research, listing optimization, and PPC management, Helium 10 or Jungle Scout are better fits.
How does the free trial work?
Every Seller 365 plan includes a 14-day free trial. You receive 7 days of access immediately upon signing up. Connect your Amazon Seller Pro or Walmart Seller account and receive 7 additional days automatically – no coupon code required. Your first payment processes only after the trial period ends.
Can I add team members to Seller 365?
The base Seller 365 plan is single-user. The Teams plan ($79/month) allows up to 10 users – add up to 9 team members, virtual assistants, or business partners. The Pro plan also supports up to 10 users plus adds commission-free reimbursements and priority support.
My Verdict on Threecolts Seller 365
Threecolts Seller 365 earns an 8.5/10 for Amazon FBA arbitrage sellers and resellers who are currently paying for multiple individual tools or are ready to build a complete operational infrastructure from day one.
The case is strong: 10 established tools – including Tactical Arbitrage and InventoryLab that tens of thousands of sellers were already paying for separately – for $69/month represents genuine value that’s difficult to argue against. The 4.8/5 G2 rating confirms the tools actually work. Commission-free reimbursements on Pro is a genuinely unique competitive advantage. And locking current pricing for life makes the timing argument real.
The honest deductions: occasional performance lag during peak usage, the tool volume can overwhelm new sellers (stage your onboarding), and private label sellers need different tools entirely. The single-user limitation on the base plan is worth knowing before assuming $69/month covers your team.
For Amazon FBA resellers doing online arbitrage, retail arbitrage, or book reselling who are paying for 2-3 of these tools separately, the math on switching to Seller 365 is straightforward. For high-ticket dropshipping entrepreneurs who also run Amazon FBA as a parallel channel, Seller 365 provides everything needed to run that operation efficiently without building a $300+/month tool stack from scratch.
