BidX for Amazon PPC: what it automates, what it costs and who it suits

What BidX does for your Amazon ads

BidX is software that runs your Amazon ads for you by rules. Amazon’s ads are PPC, short for pay per click: you bid on a search term and pay each time a shopper clicks your ad. BidX connects to your account through Amazon’s own ads API and changes those bids every day.

Two numbers steer it. ACoS, advertising cost of sales, is ad spend divided by the sales your ads brought in, times 100 (Amazon Ads). TACoS, total advertising cost of sales, divides the same spend by all your sales, organic ones included (Perpetua). Spend $1,000 and sell $4,000 through ads and $10,000 in total, and your ACoS is 25% while your TACoS is 10%.

BidX lets you set a TACoS target and steers bids towards it. Our Amazon TACoS guide works the formula through more cases.

Which jobs BidX automates

BidX’s Sponsored Ads page lists its automations. It says bids rise on keywords that sell and fall on keywords that take clicks with no sale. Search terms that convert move from automatic campaigns into manual ad groups. That last job is called keyword harvesting.

Search terms that waste money go in as negative keywords, so your ads stop showing for them.

Its rules follow an “IF THEN approach” that you can extend yourself.

The Campaign Creator builds campaigns for many products at once, and dayparting changes bids by hour of the day. BidX works on every Amazon marketplace through the Amazon Ads API (pricing page).

The same account covers Sponsored Products, Sponsored Brands and Sponsored Display, plus Amazon DSP (display and video ads bought across Amazon and other sites). Walmart Sponsored Ads run there too.

BidX Intelligence adds AI agents that rank recommendations overnight (BidX Intelligence). They recommend and change nothing in your campaigns, so you approve each move. The terms call AI output “non-binding suggestions” and ask for a “human in the loop” (sections 12.1 to 12.5).

What BidX costs and how the fee grows with ad spend

BidX charges a flat monthly fee plus a share of the ad spend you connect, and the share is blank on the card. The pricing page shows “+ %” with no figure in both currency views. The page’s hidden script holds 3% and 4% for a billing option it does not show, so ask for your percentage in writing.

The page opens in euros, and its euro figures match the dollar prices below.

“All plans are based on an annual commitment and monthly payments,” the pricing page says, and prices exclude VAT. The terms add an exit cost. Leave early after a data-switching notice and you pay 20% of the remaining fees, capped at six months (section 14.25).

Sellers under $10,000 of monthly spend get Essential at $195 a month. It automates bidding without your own rules, and the page states no billing term.

Amazon DSP has its own fee. The terms set it at 15% of DSP spend “unless otherwise agreed”, due two months in advance and never refunded (sections D 3.1 and D 3.5).

Is there a BidX free trial?

The documents disagree. The terms give 14 days of free use of the automation after you register (section B 2.1).

Booking of automation services (section B 2.1) and termination (section B 5.2)

Trial period Within the first fourteen (14) days after successful registration according to clause A. 3.2, the customer may use the automation services free of charge (hereinafter “trial period”). After expiry of the trial period, the customer may use the automation services only on the basis of a contract subject to a charge (hereinafter “subscription”).

Notice The subscription for automation services can be terminated in case of a monthly term with a notice period of fourteen (14) days to the end of the respective term and in case of an annual term with thirty (30) days’ notice to the end of the respective term.

The pricing FAQ says new customers get “a paid three-month proof of concept (POC) period”.

So plan on paying from day one unless your contract names the 14 days. Two free tools need no plan: the TACoS calculator and a Wasted Ad Spend Analyzer that reads a search term report in your browser.

What BidX reviewers on OMR and Trustpilot report

We read 54 public user sources. Forty-four are reviews on OMR Reviews, a German software review site, and ten sit on Trustpilot, dated 28 April 2023 to 27 May 2026. Most OMR reviewers run German brands or Amazon agencies, and OMR marks every review older than 12 months.

Automation draws the most praise: 43 of 54 sources name automated bids and rules, or the time they save (OMR Reviews, Trustpilot). Support comes next, praised for speed or care by 33 of 54 (OMR Reviews, Trustpilot).

Speed is the commonest complaint. Fourteen of 54 sources report slow loading or data that arrives late, most often on large catalogues (OMR Reviews, OMR Reviews, page 2). Nine of 54 say the tool takes time to learn or feels technical at first (OMR Reviews).

Requests for a missing feature or bulk tool come up in 19 of 54. Two examples: no way to edit negative keywords inside BidX, and a 20-campaign limit on bulk creation (OMR Reviews, OMR Reviews, page 2).

Two of 54 say BidX leans on rules and uses less AI than its rivals (OMR Reviews, OMR Reviews, page 2). One reviewer calls the price unattractive for small ad budgets (1 of 54 sources, OMR Reviews). One Trustpilot reviewer says nobody answered after payment (1 of 54 sources, Trustpilot).

BidX pros and cons

When BidX is the wrong pick, and what to use instead

A small account can start free. Amazon’s console has schedule bid rules that raise bids at set times and dates, launched for Sponsored Products on 6 November 2023 (Amazon Ads). Budget rules (Amazon Ads, 12 August 2021) sit in the same console, and Sponsored Products has “no monthly or upfront fees” (Amazon Ads).

A seller who wants a flat, monthly price looks elsewhere. Scale Insights charges per automated product, from $78 a month for five, with “no contracts”. Teikametrics adds 3% of spend above $10,000.

Pacvue sells by quote and publishes no price (OMR Reviews), so you book a demo to cost it. All of them sit side by side, priced at two levels of monthly spend, on the best Amazon PPC software.

BidX works on Amazon and Walmart search ads. For the video and images inside those ads, see AI tools for Amazon ads. Tools that score creative on Meta and TikTok sit on the creative research hub.

Questions buyers ask about BidX

Is BidX worth it?

Yes, if you want rules running bids on a TACoS target and spend over $10,000 a month, the point where Essential stops. Self Service then costs $495 a month billed yearly plus a share, so get the percentage in writing first.

How much does BidX cost?

Essential costs $195 a month for up to $10,000 of monthly spend. Self Service, Managed Platform and Managed Service add a share of ad spend to a yearly-commitment fee.

Does BidX have a free trial?

Its terms give 14 free days after you register; its pricing FAQ describes a paid three-month proof of concept. Ask which applies to your contract.

Is BidX an Amazon partner?

BidX describes itself as an Amazon Advanced Partner and works through the Amazon Ads API (pricing page). It calls itself “a third party Amazon Tool”.

Does BidX use AI?

Yes. BidX Intelligence runs on the Anthropic API and ranks recommendations overnight, and it changes nothing in your campaigns.
