MicroSaas Blueprint — an Amazon Ad Spending Optimization SaaS

I spend an unhealthy amount of time on Reddit.

But it’s not for the memes. I’m hunting. This week, I hit gold in r/FulfillmentByAmazon.

It’s a community of Amazon tough sellers. One post, complete with charts and a palpable sense of frustration, laid out a money leak.

The truth is, your Amazon ads are probably running 24/7. And that means you’re paying for clicks at 3 AM on a Tuesday, when your ideal customer is fast asleep.

It’s like paying a cashier to stand in an empty store all night. You’re burning money for nothing.

The Moment You See It, You Can’t Unsee It The post wasn’t just a theory. The author brought receipts. He shared hourly performance charts showing conversion rates falling off a cliff after 11 PM. For B2B products, running ads on a Saturday was the digital equivalent of setting a pile of cash on fire.

But layed out in front, from the post’s author, after doing all the hard work of manually analyzing his own data in a spreadsheet, he asked:

If anyone else doing day/hourly parting — what software do you use?

This is it.

The person who knows enough to spot the problem and fix it manually is still looking for a tool. He doesn’t want to live in Excel. Nobody does. He’s not complaining; he’s asking to buy something.

And then another comment captured the sheer chaos of being a seller:

This kind of loop usually happens when three systems are out of sync…

These people are drowning. They don’t need another monster platform that promises to “transform their entire business.” They need a single tool that solves a single, expensive problem. Right now.

The “Dumb” App That Prints Money Let’s build that tool. We’ll call it AdSnooze.

The name tells you everything it does. It puts your ads to sleep when they aren’t making you money.

That’s it. That’s the entire product.

AdSnooze connects to your Amazon account, looks at your hourly ad data, and automatically pauses your campaigns during your least profitable hours.

No keyword research. No listing optimization. Just one, simple, money-saving switch.

This is the perfect Micro-SaaS for a solo founder because the scope is tiny. You’re not trying to build a better Amazon Ads dashboard. You’re building the single, powerful button Amazon forgot to add. It’s buildable in weeks, not years. And the marketing message is as clear as a bell: Stop wasting money on late-night clicks. 😴

The Blueprint Okay, how do we actually build this?

The Bare-Bones MVP:

What’s the absolute minimum we need to solve the core pain?

A Rock-Solid Amazon API Connection. This is table stakes. It has to be secure and reliable, or you’re dead on arrival.
Pull the Data. Show the Chart. A simple script pulls the hourly campaign report once a day. The dashboard shows one thing: a chart of Ad Spend vs. Sales, by hour.
The “Snooze” Switch. Forget a fancy calendar. Start with two settings: a time-picker for “Pause ads between [X PM] and [Y AM]” and a simple checkbox for “Pause ads on weekends.”
The On/Off Script. The backend that actually makes the API calls to Amazon to pause and re-enable campaigns based on the schedule.
Bonus: in v2 of the SaaS we can think of adding new features, like monitor the ad success in real time and allow it to further optimize the budget

That’s it. No fancy AI. No garbage. Just data, a schedule, and a switch.

The Real Hurdle Isn’t Code. It’s Trust. Let’s be clear: the biggest challenge isn’t the code. It’s asking a seller to give your app permission to control their ad spend. This is terrifying. Their business depends on this. You beat this with transparency and social proof. Your landing page has to look and feel more professional than Amazon itself. You need a crystal-clear privacy policy. You need to become a helpful, known entity in the seller communities. Your first ten customers are the hard part. You’ll get them by building personal relationships, not by running ads.

The No-Brainer Price: $19/month. Flat.

No tiers. No percentage of ad spend. Just a simple, flat rate. Why $19? Because for any seller spending more than a few thousand on ads, they are almost certainly wasting over $100 a month in those dead zones. Your tool saves them $100, and they pay you $19. Win — win. It pays for itself 5x over, every single month.

Stop. Don’t Write a Line of Code. Before you build anything, you validate. Step 1: The Landing Page Test

Buy adsnooze.com.
Use Carrd to build a one-page site in an afternoon.
Describe exactly what the tool does. Use the language in this post. Show a mockup of the dead-simple dashboard.
Add a big button: “Request Early Access & Lock In 50% Off.” Make it link to a simple email form.

You now have a machine for testing demand. Step 2: Go Back

Offer Free Audits. Post in r/FulfillmentByAmazon. "Hey, I'm doing 5 free 'Ad Waste' audits. I'll manually run the numbers from your ad reports and show you exactly how much money you're burning overnight. No strings attached." This gets you real data and your first five potential customers.
Write Your Own Proof. After the audits, anonymize the data and write a new post. “I Analyzed 5 Amazon Ad Accounts — They Were Wasting an Average of 18% of Their Budget Between Midnight and 6 AM.” This makes you an authority and drives traffic directly to your new landing page.

The internet is a graveyard of abandoned spreadsheets and tedious manual workflows. They are everywhere. The complaints are the blueprints. The frustration is the feature list.
