1 The problem

Silent overspend is the expensive kind.

Rules cover what you predicted. The expensive surprises are the ones you didn't: a broad match gone viral, a broken campaign, a listing quietly suspended. Nobody writes a rule for the thing they didn't see coming.

Weeks

How long a quiet doubling can run before a human happens to read the right report. The spend is real the whole time.

Both directions

Overspend hurts the invoice. A silent drop (broken campaign, suspended listing, payment issue) hurts revenue. Silence is a signal too.

0 setup

There's no rule to write and nothing to remember. Connect an account and the watching starts. A safety net you configure can be forgotten. This one can't.

Always running, no rule required EVERY MORNING: compare yesterday to [your 14-day baseline]
IF: a +20% spike, a hard drop, or week-over-week drift
THEN: email you, with the campaigns that did it
2 How it works

Connect once. It watches from then on.

01

Connect your account

That's the whole setup. One OAuth handshake through the official Amazon Ads API, and every connected account is covered from that moment.

02

It learns your normal

A rolling 14-day baseline per account. Thresholds are relative to your own history, not a fixed dollar figure, so small sellers and large agencies both get sane alerts.

03

It checks every morning

Yesterday's settled data, checked daily for spikes and drops; a weekly pass catches slow drift. If Amazon's numbers haven't landed yet, it says "data still loading" instead of crying wolf with a false −100%.

04

You get the why, not just the what

Every alert names the top movers, the campaigns that drove the change, so 9am starts with the fix, not the investigation. Delivered by email, and Slack if connected.

3 Why Off Hours

Rules cover what you predicted. This covers the rest.

Most tools only alert on thresholds you remembered to configure. The whole point of a safety net is that it's there before you knew you needed it.

Zero configuration

On the moment an account connects. A safety net you have to set up can be forgotten. This one was never set up, so it can't be.

Your normal, not a magic number

Thresholds are relative to each account's own 14-day baseline. Growth isn't punished, drift isn't missed, and no one has to guess what "$200 too much" means.

Drops and drift, not just spikes

A blowup is obvious eventually. A campaign that quietly stopped, or creep of a few percent a week, never is. Both are watched.

The alert names the culprit

Top movers are in the email: which campaigns drove the change and by how much. The alert is the start of the fix, not just an alarm bell.

Honest about data lag

Amazon's reporting runs behind. When yesterday's numbers haven't landed, the alert says "data still loading" instead of a false alarm claiming spend fell 100%.

The floor under all five rule types

Dayparting, budget, event, performance, and bid rules act. This watches, including the hours and windows no rule reaches.

Ready to act, not just watch?

Performance rules take the same signals and respond automatically: recommendation, budget change, or pause, at thresholds you set.

4 The alternative

What watching looks like without it.

Checking the console when you remember. It works right up until the week you're busy, which is always the week something moves.

5 Questions

Spend alerts, answered.

What are spend alerts in Off Hours?

Always-on monitoring that watches every connected Amazon Ads account against its own recent baseline and emails you the morning after something moves: a spend spike, a hard drop, or slow week-over-week drift. Each alert names the campaigns that drove the change. It is included free with every Off Hours account.

Do I have to configure anything?

No. Spend alerts are on the moment an account is connected. There is no rule to write and nothing to schedule. If you want, the spike threshold can be customized per account, but the default works without touching anything.

What counts as a spend spike?

Yesterday's spend compared against the account's own 14-day baseline: 20% above normal by default, customizable per account. Because the threshold is relative to your own history rather than a fixed dollar amount, a small seller and a large agency account both get sane alerts.

Does it catch spend drops too?

Yes. A hard drop in spend usually means something broke (a paused campaign, a suspended listing, a payment issue), so silence is treated as a signal, not a savings. A weekly drift check also catches slow creep that never trips a single-day threshold.

How are spend alerts different from performance rules?

Performance rules act on thresholds you set: they can send a recommendation, adjust a budget, or pause a campaign. Spend alerts watch everything with zero setup and just tell you, with the culprit campaigns named. Most accounts run both: rules for what you predicted, alerts for what you didn't.
