Amazon PPC Performance Guarantees
Most Amazon PPC agencies guarantee nothing beyond effort. PPC Nest locks a written baseline from your trailing 90 days of Amazon Ads data before you pay a performance fee, then commits to beating it within 90 days - or keeps working at no charge until it does, with a full refund of your last month's fee if there's still no improvement by Day 120.
Search for an Amazon PPC agency with a guarantee and most of what you'll find isn't one. It's a free audit rebranded as a "guarantee," or a soft promise to "try harder" if targets aren't hit - with no number attached, no verification method, and no consequence if it doesn't happen. Some agencies guarantee a specific ACOS number without accounting for seasonality, category, or where your account already was - a number picked to sound impressive rather than to be genuinely useful to you.
A real performance guarantee requires three specific things, spelled out in writing before any performance fee is charged:
Before we sign a client, we review the brand's trailing 90 days of Amazon Ads data and agree a written baseline - ad-attributed sales and TACOS, verified in the client's own Amazon Ads dashboard.
Day 0
The baseline is locked in writing before any performance fee is charged.
Day 90
If we haven't beaten the baseline - TACOS down or ad-attributed sales up - we keep working at no additional charge until we do.
Day 120
If there's still no measurable improvement, we refund the client's last month of management fees.
The guarantee applies only to brands spending $5,000+ per month on Amazon Ads, with converting listings and no chronic stock-outs. That qualification exists because below that threshold, results depend as much on the product, listing, and inventory as they do on ad management - and we don't attach a written guarantee to variables we don't control. If you don't qualify yet, we'll tell you honestly on the call, and what to fix first.
The performance fee applies ONLY to ad-attributed sales generated above the agreed written baseline - never on sales the brand already had. Below baseline, you pay the flat retainer only. Tiers step down as the brand scales: 5% on the first tier of above-baseline sales, down to 4%, down to 2.5% - so the fee structure rewards growth instead of punishing you for it.
| Typical Agency | PPC Nest (Guarantee-Backed) | |
|---|---|---|
| Contract length | 3-12 month lock-in, early termination fees | Month-to-month, 30 days' notice, no penalty |
| Performance fee | Flat % of total ad spend or total sales, regardless of results | Only on ad-attributed sales above your written baseline (5% → 4% → 2.5%) |
| What you pay when results miss | Same retainer either way - no consequence tied to performance | Free work past Day 90, refund of last month's fee past Day 120 |
| Who verifies the numbers | Agency's own dashboard or report screenshots | Your own Amazon Ads dashboard |
Most don't - or the "guarantee" is really just an audit dressed up as one. PPC Nest's 90-Day Baseline Beat Guarantee is a written commitment: if we haven't beaten your locked baseline by day 90, we keep working free until we do, and if there's still no measurable improvement by day 120, we refund your last month's management fee.
Three things, in writing, before you pay a performance fee: (1) a specific numeric baseline pulled from your own trailing data, not an estimate; (2) a way to verify results in a dashboard you control, not the agency's own reporting; and (3) a real financial consequence if the agency misses - free work, a refund, or both. If any of those three is missing, it's not a guarantee, it's marketing language.
Your own trailing 90 days of ad-attributed sales and TACOS, pulled straight from your Amazon Ads dashboard, seasonality-adjusted so a Q4 spike never counts as an agency "beating" a July baseline. That's exactly what we lock in writing before charging a performance fee - it's the same standard we'd want applied to us.
They shouldn't, but many do - charging a flat percentage of total ad spend or total sales regardless of whether performance actually improved. Our performance fee applies only to ad-attributed sales generated ABOVE your written baseline, never on sales you already had. The tiers step down as you scale: 5% to 4% to 2.5% of the above-baseline sales.
With us: at day 90, if we haven't beaten your baseline, we keep working at no additional charge until we do. At day 120, if there's still no measurable improvement, we refund your last month's management fee. Both are written into the agreement before you sign, not verbal promises.
No - ours is stronger. A pure money-back guarantee just refunds you and ends the relationship. Ours works in two stages: first we keep working for free past day 90 to actually fix the problem, and only if that still hasn't worked by day 120 do we refund your last month's fee.
Not immediately, and we'll tell you that honestly. The guarantee applies to brands spending $5,000+/month on Amazon Ads with converting listings and no chronic stock-outs - because below that, results depend as much on the product and listing as the ad management, and we don't guarantee what we can't fully control. Newer or smaller brands can still work with us through a custom-priced Essentials engagement; the guarantee and performance-fee model apply once you're in the full Profit Partner Program.
We review your trailing 90 days of Amazon Ads data together before you sign anything, and agree a written baseline covering ad-attributed sales and TACOS. You verify it in your own Amazon Ads dashboard - not in an agency report - both when it's set and when we measure against it at day 90.
Book a 30-minute Baseline Call. We'll review your trailing 90 days and tell you - in writing - the number we'd commit to beating, how, and what it costs. If you don't qualify yet, we'll tell you that too, and what to fix first. Either way, you leave knowing your real baseline.
