Both can run your Amazon channel. They differ in who makes the calls, how the bill grows with your sales, and how much of the work you can see. Here is the comparison with published prices checked on October 27, 2026.
Short answer
A brand manager on hours is one accountable person who owns your Amazon decisions for a fixed block of time each month, priced like Evolve's $750 to $3,600 tiers. A full-service agency puts a team on the account for a flat retainer, such as Lab 916's published $5,000 a month floor, or a percent of sales. Hours stay flat as you grow; percent-of-sales fees grow with revenue.

This page compares two ways to get help running Amazon. The first is a brand manager on hours: one named person who owns the decisions for your brand and works a fixed block of hours each month. The second is a full-service Amazon agency: a team (an account lead, a PPC specialist, a creative group, sometimes inventory and account health staff) paid a large flat retainer, a percent of your sales, or both.
We already published a side-by-side of a full-service agency against buying creative projects plus a separate PPC fee. If that is your choice, read full-service Amazon agency vs a creative shop plus PPC. This page is about a different question: who sits in the driver's seat. A brand manager on hours is a single accountable owner who also coordinates specialists. A full-service agency is a department you rent.
If you want the definition of the role first, start with what an Amazon brand manager is. If you already know you want help and are weighing the bill, keep reading.
The biggest difference is not price. It is where the judgment lives. With a brand manager, one person holds the whole picture: your margins, your inventory position, your ad plan, which listing needs new images, and which new product is coming. When something goes wrong, you know whose desk it landed on. With a full-service team, the work is split by function. That brings depth in each area, and it adds handoffs between people.
Agencies describe their own model this way too. Lab 916's pricing page says its managed channel puts senior operators on strategy, ads, catalog, account health and a weekly cadence, and it lists a 3-month foundation before the contract goes to 30-day rolling (Lab 916 pricing, checked Oct 27, 2026). SupplyKick's 2026 pricing guide says the full-service tier is where agencies start running the entire Amazon operation, with a dedicated account manager plus PPC, creative and supply chain support (SupplyKick, updated Sep 14, 2026). Both companies sell that service.
Brand manager: recommends a price or coupon, you approve it, they set it. Agency: often set inside a playbook, reported in the weekly or monthly review.
Brand manager: one person weighs ad spend against stock and margin in the same sitting. Agency: the PPC specialist moves bids, and stock or margin context comes through the account lead.
Brand manager: decides what to change and briefs designers or a photographer. Agency: an in-house creative team produces it, sometimes as a separately billed project.
Brand manager: one name answers for the suppressed listing or the stock-out. Agency: a team answers, and you may need the account lead to find which person owns it.
To compare fairly, we use annual Amazon sales and leave ad spend out of every total, because Amazon bills ad spend to you in both models. For the full-service side we use three published reference points. Percent-of-revenue ranges come from agency pricing guides: 3% to 10% in SupplyKick's guide, 3% to 8% in AmpliSell's buyer's guide dated July 24, 2026 (AmpliSell), and 3% to 15% of monthly Amazon sales in an Ecombrainly guide updated June 30, 2026 (Ecombrainly). Flat retainers come from Lab 916 (from $5,000 a month) and BellaVix ($3,500 to $15,000+ a month, or 0.5% to 5% of sales, per its services page, checked Oct 27, 2026). For the brand manager side we use our own four tiers.
Below, 3% and 5% are illustrations taken from inside those published ranges, not a quote from any one agency. Your proposal may be higher or lower.
Two things stand out. First, a percent-of-sales fee grows in step with revenue, so the same 5% that costs $50,000 at $1M costs $500,000 at $10M. SupplyKick makes the same point in its guide, noting that 5% on a $10M brand is $500,000 a year. Second, the hours model is cheaper at every size in this table, but it buys less capacity. Forty hours a month is a little more than one full workday a week on your brand. A $10M brand with several marketplaces, hundreds of ASINs and a heavy launch calendar may need more hands than that, and the comparison becomes the full-service retainer against a brand manager plus specialist projects.
Production is extra in both models. On our side, photos, video, A+ design and listing copy are fixed-price projects billed separately from brand management hours (product photography from $295, listing optimization at $495 per listing, see our pricing page). Lab 916's page says large shoots and storefront rebuilds are scoped separately as well. Ask every provider what is inside the fee and what is billed on top. To run your own numbers against an in-house hire, use the Amazon agency cost calculator, and for the wider market, see what $2K, $5K and $10K a month buys.
Because one person sees ads, stock, pricing and content together, trade-offs get made in one place. Pausing ads on a SKU that is about to stock out, or shifting budget to the variation with the best margin, does not need a meeting.
You pay for hours, so a strong holiday quarter does not raise the bill. You add hours when the work grows, not when the sales number does.
An hour-based plan can be reported line by line: what was done, how long it took, what is next. That makes it easy to judge value month to month.
A team has a PPC specialist, a designer and an account health person on staff. If one is out, someone covers. That matters for large catalogs, Vendor Central, DSP (Amazon's programmatic display ads) or several countries at once.
If nobody inside the company has time to approve decisions weekly, a team that runs inside a set scope can carry more without waiting on you.
A brand manager with too few hours becomes a task-taker, not an owner. A percent-of-sales agency can be paid more for revenue that came from coupons or heavier ad spend. Ecombrainly's guide notes that revenue is not profit and that "5% of sales" needs a written definition.
List who sets prices, ad budgets, reorder quantities and creative changes right now. If the answer is "the founder, when there is time", you need an owner more than you need more hands.
Add up the hours your team spends on Amazon each week: ads, listings, cases, reports, inventory. Under about 5 hours a week, a 20-hour monthly plan usually covers it; around 10 hours a week fits a 40-hour plan. Far above that, look at a team or a mix.
Use the tables above with your own numbers. Turn any percent-of-sales quote into a yearly dollar figure at today's revenue and at the revenue you expect in 12 months.
For percent-of-sales proposals, get the definition in writing: ordered or shipped revenue, gross or net of refunds, all sales or only growth above a baseline. Ecombrainly's guide lists these as the terms to pin down.
Note the minimum commitment (Lab 916 publishes 3 months, then 30-day rolling; Evolve's plans are month to month and paid upfront) and who keeps account access, campaign files and creative at the end. Our guide to switching Amazon agencies covers the handover.
Run one product family for 60 to 90 days with clear targets before you hand over the whole catalog. Here is how to run a pilot on one ASIN.
Neither model fixes a product that does not sell or a margin that cannot carry ad spend. SupplyKick's guide tells brands not to hire an agency while Amazon revenue is under $100,000 a year or gross margin is below 15%, and says an agency usually needs 3 to 6 months to show meaningful lift. Those are a vendor's thresholds, but the logic holds for a brand manager too.
Under roughly $20,000 to $30,000 a month on Amazon, even our $750 Brand Support plan is a real share of revenue. A founder spending four hours a week on ads and listings, with a simple checklist, is often the better choice. Our Amazon brand management checklist is free.
If the main image, title or reviews are the problem, buy that fix once. Our free Amazon listing audit tells you whether it is a content problem or an operations problem.
If Amazon is your main channel and you can fund a full-time role, a hire may win on hours per dollar. See brand manager vs an in-house hire.
No honest provider can promise a sales number. Treat a guaranteed result as a reason to keep looking.
Evolve sells the hour-based model. You get one accountable brand manager, Ian Smith, who founded Evolve in 2017 and has sold on Amazon since 2015, working with Megan Smith and a set of AI agents that handle repetitive checks. Our Amazon brand management plans are paid upfront each month, month to month, and unused hours do not roll over.
Because we also make content in house, the brand manager can brief and produce photos, video, A+ and listing copy without a second vendor. Those are fixed-price projects, listed on our pricing page. Ad spend is billed separately from our fees.
What we do not do: we do not buy inventory, run your customer service inbox, keep your books or give legal advice. If one of those is the gap, you need a different hire. To talk through which model fits, book a free 30-minute call, email Ian at [email protected] or call or text 719-257-3557.
