The right answer depends on two numbers: what you spend on Amazon ads each month and how many products you advertise. We loaded the pricing pages of five PPC software tools (plus Pacvue, which publishes no price), Upwork's freelancer rate page and three agency rate cards on October 22, 2026, then did the math at $3,000, $15,000 and $50,000 a month in spend.
Short answer
Under about $3,000 a month in ad spend and 20 products, buy software: Teikametrics is $149 a month, Ad Badger $275, Helium 10 Ads $279 plus 2% of spend. From $3,000 to $10,000, a freelancer at Upwork's $20 to $45 an hour works if you can manage one. From about $10,000, an agency is cheaper than it looks: Evolve Media Agency charges a flat $1,995 a month up to $50,000 in spend, and WebFX the greater of $975 or 15% of spend up to $30,000. Pacvue does not publish a price.

worked example
PPC means pay-per-click: Amazon's Sponsored Products, Sponsored Brands and Sponsored Display ads, where you pay each time a shopper clicks. All three options on this page run the same ads in the same Amazon account. What changes is who decides what to do and who does the clicking.
Software changes bids and adds new keywords from your search reports (keyword harvesting) on rules you set. It is cheap and fast, and it does nothing you did not tell it to do. A freelancer is one person, paid by the hour or a flat monthly amount, who runs the account and usually works inside your software. An agency is a team on a monthly fee that owns the strategy, the build and the reporting, and normally brings its own tools.
Two numbers matter most. The first is monthly ad spend, because every fee is easier to judge as a share of it. The second is SKU count, meaning how many separate products (each with its own ASIN, Amazon's product ID) you advertise. Ten products with a few campaigns each are a weekend job. Two hundred products across variations are a full-time job.
Software, run by you. At this size any agency fee is 30% or more of your spend. Teikametrics at $149 or Ad Badger at $275 handles the bids; you spend two to four hours a week on search terms.
Software plus a freelancer, or a flat-fee agency at the low end. A freelancer for 10 to 15 hours a month at $20 to $45 an hour is $200 to $675, plus your tool.
An agency on a flat fee. The fee falls to 4% to 20% of spend, and you stop being the person who checks the work.
An agency with a team, often on a percentage of spend, plus enterprise software such as Pacvue. Flat fees at our level stop buying enough hours.
If you or someone on staff can read a search-term report and knows why a keyword is wasting money, software at $78 to $339 a month does the repetitive bid work and an agency adds little.
A single product with a few dozen proven keywords does not need weekly strategy. Scale Insights' Scale 5 plan covers five automated ASINs for $78 a month. Set the rules, check weekly, and spend the savings on the listing.
You know enough to check the work and want 10 to 15 hours a month done for you at $200 to $675. Keep admin access, ask for a weekly change log, and pair them with a tool you own.
If nobody has opened the search-term report in a month, software has been spending on rules nobody reviewed. That is the point where a named person with stated hours earns the fee.
Flat fees fall as a share of spend: our $1,995 is 13% of $15,000 and 4% of $50,000. Seventy-five products across variations need structure, naming and budget rules that a freelancer working 10 hours a month cannot keep up.
A new product needs a launch plan, a bid strategy for the first 60 days and fast reaction to early data. Software has no history to work from yet.
These are worked examples using the published prices above, checked Oct 22, 2026. Freelancer figures are ballpark estimates built from Upwork's hourly band. The ad spend itself is on top in every case and is not included. Percentages are the fee divided by monthly ad spend.
Spend tells you what a fee costs as a share. SKU count tells you how much work there is. Scale Insights prices by it, which makes the effect easy to see: 5 automated ASINs are $78 a month, 20 are $178, 50 are $388 and 100 are $688. A brand spending $5,000 across 100 ASINs has far more campaigns to watch than one spending $15,000 on 3 ASINs.
As a rule of thumb: under 20 advertised SKUs, one person with software can keep up in two to four hours a week. From 20 to 75, the weekly search-term work starts to take a full day. Above 75, especially with size or color variations, you need naming rules, portfolio budgets and someone whose job it is. That is when a freelancer gets stretched and an agency, or an in-house hire, starts to pay.
Amazon charges no monthly fee to run Sponsored ads. Start with Amazon's own console and a weekly search-term review. Our minimum spend is $1,000 a month for this reason.
Every click from every option lands on the same page. If the main image, bullets, price or reviews are weak, fix the listing first. Our listing copy is $495 and the listing audit is free.
If you do not know your margin after Amazon fees, nobody can set a target ACoS. Work out the break-even ACoS first: your margin before ad cost, as a percentage of price.
Any tool or person can hit a low ACoS by cutting spend until sales fall. Judge on TACoS and total sales, not one ratio.
Ads on a product that cannot ship waste spend and can hurt ranking. Fix inventory, then advertise.
Pick for where you are going. A flat fee that is 33% of spend today might be 10% after a launch.
Count ASINs with spend in the last 30 days, not your whole catalog.
If the answer is nobody, software alone will keep spending on rules no one reviews.
Whatever you choose, the Amazon account and the tool should be in your name, with the helper added as a user.
If the answer is product development or wholesale deals, the management fee is buying something. If not, run it yourself.
