Amazon PPC agency vs in-house vs software tools: a 2026 comparison

The short answer

Hire in-house when your Amazon ads are large enough to fill a senior person's week and you are ready to manage that person. Buy software when you already have someone who can set its rules and judge its results. Hire an agency when you want experienced judgement and a result you can hold someone to, without adding a salary. Running the ads yourself makes sense while the account is small enough that your hours are better spent there than anywhere else in the business.

The four options side by side

Hiring in-house

The federal job statistics do not count Amazon PPC as a job of its own. The nearest category, market research analysts and marketing specialists, had a median annual wage of $78,760 in May 2025. Benefits come on top: in June 2026, wages and salaries were 70.0 percent of private employers' compensation costs, and benefits the remaining 30.0 percent. On that basis, our own arithmetic puts the total cost of a median salary at about $112,500 a year.

An employee gives your brand full attention, learns your products closely and sits with the rest of your team. In exchange, one person carries the account, the search for the right person takes time, and you must be able to judge their work. A specialist who has run one account has also seen fewer situations than a team that runs many.

Buying software

Amazon describes tool providers as firms that offer "specialized tools or software as a service (SaaS) solutions" for managing and improving campaigns. One provider publishes $149 a month billed yearly, or $179 billed monthly, for up to $10,000 of ad spend, and custom pricing plus 3% of ad spend above $10,000 for larger accounts.

Software is quick to start and applies its rules the same way every hour, which suits a brand with an experienced person in-house. It applies the rules it is given. Someone must still choose the goals, read the search terms, decide what a rule should do with a new product, and answer for the result.

Hiring an agency

An agency brings a team that has seen many accounts and can start once goals are agreed and access is given, with no salary or hiring risk. Its fee is usually a percentage of ad spend, a flat fee or a mix, and the published examples include 7% of ad spend with a $2,500 minimum and a tiered schedule from 15% down to 10%.

The risks sit in the choice of agency. The senior person who sells may not be the person who runs the account, a fee that rises with spend may make a larger budget look attractive whether or not it pays, and your account shares the team's attention with other clients. The guide to choosing an agency sets out the questions that bring these risks into the open.

Running it yourself

Running the ads yourself costs no fee and keeps every decision with you. Amazon offers its own courses and certifications, from sponsored ads onward. The price is your time, which at this size of brand is usually needed elsewhere, and the slower pace of learning on your own account.

Which to choose

The four can be combined. A brand with an e-commerce lead in-house may keep that person on stock, listings and pricing, and hire an agency for the ads, with the lead holding the agency to its written goals.

If you already employ someone who knows Amazon ads well, software may be all they need. If no one in your team does, software alone leaves the decisions unmade. If your ads are large enough that a mistake costs more than a fee, and you would rather hold one firm to a written result than manage a hire, an agency is the closer fit.
