Ready to start making money?

Let’s dive into five proven ways to earn $400 in just 10 days!

 

Sell Digital Products (Quick & Scalable Income) #1

One of the fastest ways to make money online—without worrying about shipping or inventory—is by selling digital products.

The best part?

You create it once and sell it over and over again, making it a low-cost, high-reward way to earn.

Here’s why digital products are a game-changer:

#1 Low upfront costs – No need to buy materials or stock up on inventory.

#2 Passive income potential – Once it’s listed, you can keep making money from it without extra work.

#3 Scalable – You’re not limited by time like traditional freelance work.

So, what can you sell?

Here are a few ideas to get you started: Printables & Templates

Think planners, journals, budgeting worksheets, or even social media templates. People love ready-to-use designs! 

You can sell them on Etsy, Gumroad, or your own website.

E-books & Online Courses If you have knowledge to share, package it into an e-book or course.

Platforms like Udemy, Gumroad, or Shopify make it easy to sell. 

Stock Photos & Graphic Designs – If you're into photography or design, upload your work to sites like Shutterstock, Adobe Stock, or Creative Market and get paid every time someone downloads it.

The key is to create something valuable that solves a problem or makes life easier for your audience.

Once you have your product, promote it on social media, Pinterest, or even through an email list to start generating sales.

This is one of the best ways to make quick money and build a long-term passive income stream at the same time! 

 

Start Freelancing (Get Paid for Your Skills Fast) #2

If you need to make money quickly, freelancing is one of the best ways to get paid for your skills—sometimes within just a few days!

The beauty of freelancing is that you don’t need a fancy degree or years of experience.

If you have a skill that businesses or individuals need, you can start making money right now.

Sell Unused Items (Declutter & Earn Cash) #3

Got stuff lying around that you no longer use?

Turn your clutter into cash!

Selling unused items is one of the quickest ways to make money because you’re not creating anything from scratch—you’re simply finding buyers for things you already own. 

Plus, it’s a win-win: you make money and free up space in your home.

Where to Sell Your Stuff Fast To get the most cash quickly, you’ll want to list your items on platforms where buyers are actively looking:

eBay – Great for selling collectibles, electronics, and branded items to a global audience.

Facebook Marketplace – Perfect for selling locally. No shipping hassles, and you can get paid in cash.

Tokopedia (for Southeast Asia users) – A great option for selling a variety of items quickly.

What Sells Fast? If you want to reach $400 quickly, focus on high-demand items that people are always looking for:

#1 Fashion & Accessories – Branded clothing, designer handbags, and shoes (especially if they’re in good condition) can sell fast.

Bonus tip: Mention brands in your listing title to attract more buyers! 

#2 Electronics & Gadgets – Old smartphones, laptops, headphones, and gaming consoles sell like hotcakes.

Even if something is slightly damaged, you can sell it for parts. 

#3 Books & Collectibles – Rare books, vintage toys, trading cards, and even old video games can fetch good money if they’re in demand.

Look up completed listings on eBay to see how much similar items have sold for.

 

Tips to Sell Fast & Get Paid Within 10 Days

 #1 Take clear, high-quality photos – Good lighting and multiple angles help your item stand out.

#2 Write a compelling description – Be honest about the condition and include keywords buyers might search for.

#3 Price competitively – Check what similar items are selling for and price yours slightly lower for a quick sale.

#4 Use local selling options – Facebook Marketplace and Tokopedia allow you to sell without waiting for shipping. Meet buyers in a safe, public place and accept cash or secure payment methods.

#5 Offer bundle deals – Selling multiple items together can move your inventory faster and help you hit your $400 goal quicker.

This is one of the fastest ways to make money because you can often get paid the same day you sell.

So, start looking around—your next $400 could be sitting in your closet or garage!
