Amazon tells you which ad sold which unit. That part is easier than Meta. The hard part is volume: a grown account has thousands of keywords, product targets and negatives across Sponsored Products, Brands and Display, and every bid should move as the data does. Nobody keeps up with that by hand.
Amazon PPC software exists to do the repetitive work. We ranked ten options the way a buyer would: how much of the grind it removes, whether you can see what it changed, and what the pricing model actually rewards. Merch Jar is first because it is strong on all three. The rest are smaller or more specialised tools, a couple of European platforms, a managed-service option, and Amazon’s own free console features. The giant names are left off on purpose.
Prices and claims were checked against each vendor’s public site in September 2026. Only Merch Jar is linked.
TL;DR
- Merch Jar: best for buyers and agencies who want rule-based automation and an AI copilot that shows every change before it runs.
- Epinium: best for brands that want catalogue, ads and reporting in one agentic platform, with a free tier.
- Autron: best for sellers who want a free AI agent to start with and a cheap Pro tier.
- ADFERENCE: best for European brands with fixed ad budgets who want a flat fee and no percentage of spend.
- Amazon’s console: best free starting point, with bid rules, budget rules and bulksheets built in.
1. Merch Jar
Best for: buyers and agencies managing several Amazon accounts who want speed with an audit trail.
Merch Jar is Amazon ads automation that shows its work. You connect your own AI client to the account, the copilot writes the automation, and you see every proposed change before it runs. The building blocks will feel familiar if you already use Meta automated rules, and they go further: Segments are custom bid rules that can look across more than one timeframe; Smart Campaigns promote or negate search terms from performance; bulk actions update bids or pause keywords from the ad manager; and every rule can be previewed before you turn it on.
It is an Amazon Ads verified partner. A public customer quote describes cutting weekly ad time from about six hours to one or two. Pricing is published and flat, with a spend allowance included rather than a surprise bill.
Why it’s number one
- Preview before a rule goes live, so you can read the tool’s decisions the way you would a junior buyer’s.
- Published pricing (checked on the pricing page): Standard is $199 a month billed annually ($300 month-to-month), includes $7,500 of monthly ad spend, then 3% overage on annual billing or 4% on monthly, and 100,000 active ads. Premium is $399 a month billed annually ($600 month-to-month), includes $20,000, then 2% overage, and 500,000 active ads. Partner is custom above $100,000 of monthly spend, with unlimited active ads.
- A 14-day trial with full features and no card. Copilot and API are on every plan, not locked to Premium.
- You can connect more than one Amazon ad account.
Tradeoffs
- The pricing page says automation covers Sponsored Products today. If Sponsored Brands or Display is the job, confirm coverage before you switch.
- Overage is still a percentage of spend above the allowance, so model it once the account is past $7,500 or $20,000.
2. Epinium
Epinium is an agentic platform that automates catalogue management, advertising and reporting across retail channels, for brands, manufacturers and retail media agencies, on Seller Central and Vendor Central. Bids, budgets and structure are managed against profit rather than ACoS alone, and the higher tiers write ads and can run unattended. It also handles stock checks, catalogue updates and reorder points, connects to Shopify, and has a Google Ads assistant. It is an Amazon verified partner.
Pricing has a free Brain tier, then Guru from €159 a month (view and pause only), Business from €349 with full automation, and Master from €799 for unattended execution, with a seven-day trial and no card. On Business and Master a percentage of AI-managed ad spend applies, from 5% down to 2%.
Best for: brands that want catalogue, ads and reporting automated together and are comfortable with a spend component.
3. Autron
Autron is an AI advertising platform for Amazon sellers, from new brands to established ones. It runs 24/7 optimisation including dayparting, keyword and competitor ASIN harvesting, playbooks, Slack and email digests, and Claude or ChatGPT integration. It quotes 50 million+ bids optimised a week, covers Sponsored Products, Brands and Display on Pro across unlimited marketplaces, and is an Amazon Ads verified partner.
Pricing is credit-based: a free plan with five credits a day, an Agent plan from $50 a month, and Pro at $150 a month plus a small share of Autron-attributed ad sales (2% falling to 0.5%). The full optimiser is Pro only. Cancel any time.
Best for: sellers who want to start free and step up to a cheap AI optimiser that covers all three ad types.
4. ADFERENCE
ADFERENCE is a German bid-management platform, a wholly owned subsidiary of ABOUT YOU since 2019, covering Sponsored Products, Brands and Display for brands and agencies on seller and vendor accounts. It automates bids, structures campaigns, discovers keywords, adds negatives and manages a Smart Portfolio Budget. It is an Amazon Ads Advanced Partner.
Pricing is by ad budget, with no percentage of spend: Growth at €629 a month (€569 annually) for up to €10,000 of monthly ad budget and three accounts; Professional at €1,259 (€1,149) for up to €25,000 and five accounts; Enterprise at €1,899 (€1,699) for up to €50,000 and eight accounts. There is a one-time onboarding fee of €999 and a three-month trial offer.
Best for: European brands and agencies with predictable budgets who want a flat fee and a parent company behind the vendor.
5. AiHello
AiHello is an AI Amazon ads platform for private-label sellers, agencies and marketplace managers. It optimises bids hourly and daily, creates campaigns, adds and removes keywords, controls negatives, and adds repricing and refund recovery on the side. It covers Sponsored Products, Display and Brands, shows a 4.6 rating on G2 and says 5,000+ sellers trust it.
The Smart plan is $199 a month per marketplace plus 2% of ad spend, advanced features are $10 per SKU per month each, and an expert-managed option is priced on request. Model the stack of per-marketplace, per-SKU and percentage fees before you sign.
Best for: sellers in one or two marketplaces who want an AI running bids and are happy with a spend component.
6. Daniks.AI
Daniks.AI is an AI agent that manages Amazon PPC to hit and hold a target ACoS. It adjusts bids, harvests keywords, manages negatives, scouts competitors and creates keyword and product-targeting campaigns across the US, Canada, Mexico, Brazil, the UK, Europe, the Middle East, Japan and Australia. It is listed in the Amazon Ads Partner Directory.
Pricing is tiered by ad sales: a 14-day trial covering 100 SKUs per country, then Lite at $49 a month, Plus at $129 for up to $15,000 a month in ad sales, Growth at $299, Scale at $599 and Enterprise on request. Sponsored Brands and Display are not named, and the reviews quoted on the site are for the company’s own Amazon product rather than the software, so judge it on the trial.
Best for: sellers who want a cheap, target-ACoS agent for Sponsored Products and will verify it on their own account.
7. Intellifox
Intellifox is where Viral Launch now points. Viral Launch, whose Kinetic PPC tool was renamed Ad Sprout and then closed to new customers in January 2026, redirects to Intellifox, formerly Seller Suite. It bundles listing optimisation, ad automation, review management and fee tracking. The ads side optimises campaigns against conversion goals, with all Amazon regions supported.
Pricing is the lowest on this list: one Amazon account for $29 a month covering 100 ASINs and ten optimised campaigns, or unlimited accounts for $59 a month covering 500 ASINs and 100 campaigns, with a seven-day trial and no card. The site quotes 400+ customers. Ten campaigns is a small cap, and no ad types are named.
Best for: small sellers who want listings and a little ad automation in one cheap tool, and for former Viral Launch users deciding where to go.
8. BidX
BidX is a German automation platform, acquired by Worldeye Technologies in 2025, used by what its site calls 2,000 brands and agencies. It automates bids and budgets, creates campaigns, suggests campaigns through ChatGPT, automates DSP custom audiences and offers AI agents it calls BidX Intelligence, across Sponsored Products, Brands and Display, Amazon DSP, Amazon Marketing Cloud and Walmart Sponsored Ads. It is an Amazon Advanced Partner.
Pricing is €495 a month plus a percentage of connected ad spend for self-service, €1,995 plus a percentage for the managed platform and €4,995 plus a percentage for the managed service, on an annual commitment, with a paid three-month proof of concept. The percentage is not stated on the site.
Best for: mid-sized brands and agencies that want DSP and AMC covered and can commit for a year.
9. Sellozo
Sellozo’s homepage headline is Amazon ads built for profit, not ad spend, and its banner promises flat-rate pricing with no percentage of ad spend and a 30-day free trial. It sells AI-powered Amazon ad automation with a separate offer for agencies and a repricer alongside. The site renders almost nothing without JavaScript, so a crawler sees only the page titles. Third-party write-ups from 2026 describe AI bid optimisation, a Campaign Studio, budget balancing, keyword harvesting and negative keyword management, and report a fee of about $250 a month for the first marketplace and $50 for each additional one.
The flat-fee model is rare, and Sellozo is a long-standing name, but the feature list and prices above are reported rather than read from the site. Confirm them in a browser before you sign.
Best for: sellers who want a flat fee across several marketplaces and will verify the current price themselves.
10. Amazon’s console
Amazon’s own console has more automation than most sellers use. Bidding rules for Sponsored Products raise bids at chosen times of day, days of the week or date ranges, and event-based rules raise them during high-traffic events. Budget rules increase budgets on a schedule or when a campaign clears a performance threshold. Bulksheets let you create and edit many campaigns from a spreadsheet across Sponsored Products, Brands and Display, and campaign presets give newer sellers ready-made settings.
The gaps define the market: those bid rules only increase bids and only on Sponsored Products, bulksheets are manual, and only campaigns with impressions in the last 60 days can be exported. Everything above exists to fill them.
Best for: every seller, before spending a dollar on software.

Three things decide whether an Amazon PPC tool pays back.
- Coverage. Does it manage the ad types you actually spend on? Several tools name Sponsored Brands and Display. Merch Jar’s pricing page currently says Sponsored Products.
- Transparency. Can you see a change before it happens and reverse it afterwards?
- The pricing model. Flat fees with a spend allowance, or flat budget tiers like ADFERENCE, are predictable. Percentages of spend or ad sales grow with the account whatever the results, and per-SKU add-ons can double a bill.
None of this is unique to Amazon. It is the same discipline that separates a clean Meta launch from a chaotic one: know what the tool did, and pay for outcomes rather than for volume.
Frequently asked questions
How is Amazon PPC software different from Meta ads automation?
Amazon tools work mostly on bids, keywords and negatives, because Amazon does the attribution and the creative is the listing. Meta tools work mostly on launching and creative, because that is where the leverage is. Both need automation you can audit.
Should I pay a percentage of ad spend?
Only with your eyes open. A 3% fee on spend above an allowance is easy to ignore until the account scales. Flat pricing with a spend allowance is easier to budget and does not reward spend for its own sake.
Do these tools work for Vendor Central?
Epinium and ADFERENCE name vendor accounts. Merch Jar’s public pricing page talks about Sponsored Products campaigns and multiple ad accounts, not vendor vs seller. Ask before you connect.
What about Amazon DSP?
BidX covers DSP directly. For most sellers, DSP is a separate decision from Sponsored Ads automation, and usually a later one.
The short version
Merch Jar is the pick for buyers who want automation with an audit trail and a published price. Epinium and Autron are strong if you want an agent doing more of the work, ADFERENCE if you want a fixed fee and a big parent, and Amazon’s own rules and bulksheets cost nothing and should come first.
Once the Amazon account is running itself, the hours go back into launching more of what works. On Meta, that means a bulk-launch workflow that handles naming, enhancement locks and post IDs, so the winners get scaled the same afternoon.
