Short answer
An Amazon Relay auto booker is a browser extension that refreshes the load board and books loads that meet minimums you set, such as net profit or pay per mile. Cancelling a booked load hurts your acceptance score.
What an Auto-Booker Does
An auto-booker extension (also called an autobooker or auto-book tool) refreshes the Relay load board constantly and books loads that match the rules you set. You don't have to click Book. The extension does it automatically.
Example: You set rules that say "book any load from Portland to Eugene for $400 or more, if the profit is at least $150 after costs." When a load matching those criteria posts, the extension sees it and books it for you. Then you review what you got (NudoIQ can send each AutoBook to Telegram, if you connect it).
The advantage is obvious: you can act on loads faster, and you're not glued to the screen. The risk is equally obvious: without good guardrails, you can book loads that don't work for your operation.
The Risk of Unintended Bookings
Your biggest risk with an auto-booker is rules that are too loose. A made-up example: a rule that says "book any load paying $400 or more" will also book a 400-mile run at $400, which is $1 a mile and may not cover your costs. A rule that says "book anything from Oregon" can book a load that ends hundreds of miles from where you planned to be.
Auto-bookers book fast and without mercy. If your rules match, they book. No "wait, let me think about this." No second-guessing. If you set the rules wrong, you'll book loads you didn't want.
This is why guardrails matter. The best auto-bookers make it hard to book the wrong load.
Essential Guardrails: Rules, Profit Floor, and Max-Books Cap
A good auto-booker includes three kinds of rules:
Booking Rules: Filter the loads the extension will consider. You can specify:
- Lane: Only book loads from Portland to Eugene. Don't book Portland to Los Angeles.
- Price Range: Only book loads between $300 and $600. Don't book anything cheaper or more expensive.
- Distance: Only book loads up to 500 miles. Skip loads that are too long.
- Load Type: Book only dry van. Skip refrigerated or container loads if you don't have that equipment.
- Pickup Time: Only book loads that pick up between 6 a.m. and 4 p.m. Avoid overnight pickups you're not prepared for.
Booking rules narrow the field. They say "of all the loads on the board, only consider these ones."
Profit Floor: Set a minimum profit the extension must see before it books. Example: "Don't book anything that nets less than $150 after subtracting driver pay, fuel, maintenance, and deadhead."
A profit floor is your second line of defense. Even if a load is in your Relay search and clears your $/mile and load-pay minimums, the extension checks the net profit. If it doesn't clear the floor, no book.
Max-Books Cap: Set a maximum number of loads the extension will book. Depending on the tool, the cap counts per day, per week or per run (in NudoIQ, Max books is 1 to 20 per START). Example: "Stop booking after you've booked 5 loads."
The max-books cap is your third line of defense. It prevents you from overbooking and running out of drivers. Once you hit the cap, the extension stops booking for that period, even if perfect loads post.
Together, these three guardrails protect you from booking loads you didn't intend.
The Three Modes: Alert, Search, Autobook
Different auto-booker extensions offer different modes:
Alert Mode: The extension refreshes the board and tells you when a load matches your rules. In NudoIQ that's a sound on the page, plus a Telegram message with the load details if you connect Telegram. You decide whether to book. You stay in control but have to respond quickly, because other carriers might book the same load while you're thinking.
Alert mode is good when you want to be involved in the decision but don't want to stare at the board. It's also good for testing your rules before you turn on Autobook: use Alert mode first, see what loads it suggests, and verify they're the right ones.
Search Mode: The extension refreshes the board and highlights loads that match your rules. You scan the board, see the highlighted loads, and click Book if you want. You stay in control and can visually inspect a load before booking. But you have to be looking at the board, and other carriers might book the load while you're reading it.
Search mode is good when you want to make the final decision but want the extension to do the scanning for you. It's also good for less time-sensitive work: if you're not in a race to be first, you can look and decide.
Autobook Mode: The extension refreshes the board, finds loads matching your rules, and books them automatically. The extension handles the booking; you don't have to watch the screen, but your browser has to stay open. NudoIQ sends each AutoBook to Telegram if you connect it.
Autobook mode is the most hands-off but requires the most confidence in your settings. You need to trust that your minimums (net profit, $/mile, load pay) and your max-books cap will produce bookings you want.
Setting Your Booking Rules Carefully
To make sure Autobook books only what you want, follow this process:
Step 1: Define Your Operation
- What lanes do I actually run? (e.g., Portland to Eugene, Portland to Seattle, Portland to Los Angeles)
- What's my minimum profit per load? (e.g., $150 net)
- What's my maximum distance? (e.g., 400 miles)
- What's my maximum number of drivers available? (e.g., 5, so I'll book 5 loads max at a time)
Write these down. They're the foundation of your rules.
Step 2: Start with Alert Mode
- Run your usual Relay search for lane and equipment, then set your Min $/Mile in Alert mode.
- Let it run for a day or two.
- When it alerts you, read the load and ask: "Would I have booked this?"
- If yes, great. If no, adjust your rule.
Alert mode is a testing ground. Use it to verify your rules produce the loads you want.
Step 3: Add a Profit Floor
- Once the alerts look right, set a profit floor.
- Example: don't book anything under $150 net.
- Let it run another day.
- Again, ask: "Is it suggesting loads I'd actually take?"
Step 4: Set a Max-Books Cap
- Decide how many loads you can handle at a time. (Don't overbuild.)
- Set the cap to that number.
- Example: cap at 5 loads. In NudoIQ, Max books counts per START.
Step 5: Try Autobook
- Once you're confident in your rules, switch to Autobook.
- Let it run and watch what it books.
- In the first day or two, check that it's making the right decisions.
- If it books something you don't want, adjust the rule that allowed it.
This progression, Alert → Search → Autobook, lets you test your rules before automation takes over. The common mistake is jumping straight to Autobook. Taking time to verify the rules in Alert mode costs no money and saves headaches later.
What Autobook Actually Books
When you're running Autobook and a load matches your rules, the extension clicks Book for you. It submits the booking through the board, just as if you had clicked.
From Amazon's perspective, you booked the load. It's your obligation. You accepted it. If you can't take it later, cancelling hits your acceptance score, and the closer to pickup, the bigger the penalty.
This is why profit floor and max-books cap are non-negotiable. If you set a bad rule and the extension books 10 loads you can't handle, you cancel most of them and your scorecard suffers.
Instant Book: One-Click Booking
Some extensions (including NudoIQ) have an Instant Book button. In NudoIQ, it sits on highlighted load rows, and one tap books the load. There's no confirmation screen, so check the load before you tap.
You still press Instant Book yourself, after you've looked at the load and decided you want it. It isn't automatic.
Common Autobook Mistakes
Mistake 1: Too-Loose Rules Setting rules that are too broad ("book any load over $100" or "book anything from California") leads to unwanted bookings. Start narrow and widen only after testing.
Mistake 2: No Profit Floor A $500 rate sounds good until you realize it nets $50 after paying your driver and fuel. Always set a profit floor.
Mistake 3: No Max-Books Cap Without a cap, the extension books loads all day, and you run out of drivers or time. Set a cap to match your actual capacity.
Mistake 4: Not Testing in Alert Mode First Jumping straight to Autobook without testing your rules is asking for trouble. Use Alert mode first. See what it suggests. Verify it's the right stuff. Then automate.
Mistake 5: Setting a Cap Too High "I'll book 20 loads at once" sounds ambitious until you realize you only have 5 drivers. Be realistic about your capacity and set your cap accordingly.
How NudoIQ's Autobook Works
NudoIQ's control bar includes three modes: Alert (sounds an alert), Search (refreshes quietly and floats new and price-up loads that clear your minimums to the top), and Autobook (books automatically). Lane, equipment and dates come from your Relay search, because NudoIQ works on the loads your board shows. In NudoIQ you set Min $/Mile, Min Net Profit and Max books (1 to 20 per START).
The extension uses Net Profit calculation to check whether a load clears your profit floor. So you're not just setting a dollar target: you're setting a profit target after costs.
Instant Book is one click on the load card. If you connect Telegram alerts, they tell you when the extension books something, so you know immediately what was booked.
If you're unsure about your rules, start in Alert mode and let NudoIQ suggest loads for a day. See if the suggestions are good. Then switch to Autobook.
To get AutoBook on your own Relay board, follow the four steps in our Amazon Relay Chrome extension guide.
If you're weighing tools, here's how Load Fetcher and NudoIQ differ on auto booking, going by LoadFetcher's own listing and plans.
Setting a Profit Floor in NudoIQ
When you set a profit floor in NudoIQ, you're saying "don't book anything that nets less than $X per load after subtracting driver pay, fuel, maintenance, and deadhead to pickup."
Example:
- Posted rate: $600
- Driver pay: $150
- Fuel: $100
- Maintenance: $50
- Deadhead to pickup: $50
- Net profit: $600 - $150 - $100 - $50 - $50 = $250
If your profit floor is $150, this load clears it. If your floor is $300, it doesn't. NudoIQ calculates this for every load, so your Autobook rule respects the floor automatically.
When NOT to Use Autobook
Don't use Autobook if:
- You're not sure about your rules yet. Test in Alert mode first.
- Your operation changes frequently (different lanes, different equipment). Manual booking gives you more control.
- You're in a learning phase and don't yet know what works for you. Autobook is powerful once you know your business.
- You have unreliable internet. If your connection drops while a load is booking, it might book but you might not know.
Use Alert mode or Search mode as long as you need to. There's no shame in manual booking while you're learning.
