Tools for Building Passive Income Assets

Search for passive income tools and you will find endless lists of software, most of them promising to "automate" your way to income. The honest position is more modest. A tool can save you time on a task, but it cannot supply the parts that actually earn money: something people want, and a way for them to find it. Use tools to remove friction, not to replace that thinking.

The short answer

You need a small number of tools, chosen after you know what you are selling. This page looks at two well-known examples of the kind of tool that matters: Gumroad for selling digital products and Printful for print-on-demand fulfilment. Both make starting easy. Neither makes selling easy, and both take a share of what you earn. For the wider strategy, see our guide to passive income and our comparison of active and passive income.

What a tool can and cannot do

Building an income asset involves four jobs: making something, getting it seen, taking payment and delivering it. Tools help mostly with the last two. A platform can host your product, process payments, send the file and store customer records. It cannot decide what to make or bring you customers, apart from limited marketplace exposure in some cases.

That distinction saves money. If you are still unsure what to make, a subscription to a design suite, an email platform and an analytics dashboard will not help. If you have a product people are asking for, a simple selling platform is usually enough to start. Add tools when a specific problem appears, such as needing to email buyers or track where visitors come from, not before.

Gumroad

Gumroad is a platform for selling digital products such as guides, templates, courses, software and memberships. You upload your file, set a price, and it provides a checkout page and delivers the product to buyers.

What is good. There is no monthly fee, so you pay only when you sell, which suits testing an idea. Gumroad states on its pricing page that since January 1, 2025 it has acted as the merchant of record, meaning it collects and passes on sales tax, VAT and similar taxes on your behalf, which removes a daunting task for a solo seller with customers in many countries. Setup is fast and the interface is simple.

What is difficult. The fee structure is a percentage plus a fixed amount per sale, and it does not fall as your sales grow, so successful sellers may find it expensive. Sales that come through Gumroad's own marketplace carry a much higher rate than sales you drive yourself, which is worth knowing before you count on them. Card processing costs are separate. Reportedly, fees are not returned when you refund a customer, and the checkout is branded as Gumroad's rather than yours. Read the current pricing and payout terms on the official site, since they change.

Best suited to people testing a first digital product who want minimal setup and no fixed costs. Once a product sells steadily, it is sensible to compare the total cost with alternatives. Our guide to selling digital products covers what to make and how to sell it.

Printful

Printful is a print-on-demand and fulfilment service. You design products such as shirts, mugs or posters and connect Printful to a store, for example on a marketplace or your own site. When a customer orders, Printful prints and ships the item, and you pay it the production and shipping cost.

What is good. You never hold stock or pay for a print run in advance, so the financial risk of a new design is low. It connects to several common store platforms, and you can order samples of your own products to check quality before promoting them.

What is difficult. Margins are thin once production, shipping, store fees and advertising are counted, so the design and the audience have to do the heavy lifting. The customer sees your shop, not Printful, so delays, misprints and complaints are your responsibility to resolve. Standing out in a crowded market is the real challenge, since anyone can print the same blank items. And it is not passive: someone still has to design, list, promote and answer questions.

Best suited to people with a distinctive design or niche audience who want to test products without stock. See our guides to print on demand, selling on Etsy and Amazon and the Etsy platform guide.

The head-to-head table

When you do not need a tool at all

Plenty of first products do not need a specialist platform. You might sell a template directly through a payment link, deliver a guide by email or begin with a handful of manual sales to learn what customers want. A product with no buyers is not improved by better checkout software. Our page on free versus paid ways to make money online explains how to test an idea cheaply before spending.

Marketplace or your own store?

A recurring decision for anyone selling products is whether to rely on a marketplace, where the platform brings some of the customers, or on a store you control, where you bring all of them. Each choice trades one thing for another.

A marketplace gives you an existing audience and a lower barrier to a first sale, particularly for a new seller with no following. The price is a higher cut on the sales it sources, less control over presentation and pricing, and the risk that rules or search rankings change under you. It is a sensible place to validate a product, because a few real sales teach you more than any amount of planning.

Your own store, or sales through direct links, keeps more of each sale and lets you build a customer list you own. The cost is that nobody arrives unless you bring them, through content, social media, search or advertising. For a beginner with no audience, that means the first sales are slow, however clean the checkout looks.

A practical approach is to use both in sequence. Start where the customers already are, learn what sells and to whom, and use that knowledge to build an audience you can send to your own channel. Over time the share of sales you control can grow, which lowers your average fee and reduces dependence on one platform. Whichever route you take, work out the take-home amount per sale after every fee before you set a price, and revisit it once you have real sales data.

Platform dependence and how to reduce it

Building on someone else's platform is convenient and risky in equal measure. Fees can change, features can be removed and accounts can be restricted, sometimes with little warning. The way to reduce that risk is to own what you can. Collect the email addresses of your buyers where the platform allows, keep copies of your products and customer records, and avoid depending on one marketplace for all your sales. Treat a platform as a shop you rent, not land you own.

Tax still applies to you

A platform handling sales tax on the sale does not remove your own obligations. The income you earn is generally taxable where you live, and you need to keep records of sales, fees and costs. Check the rules that apply to you, and see our guide to tracking online income and taxes.

A sensible way to start

Begin with something small you can make in a few weeks, such as a template, checklist or short guide, or a small set of designs for a niche you understand. Put it on a simple platform and share it with real people who fit your audience. Track visits, sales and questions. If nobody buys, the fix is usually the offer or the audience, not the tool. If people do buy, improve the product, then consider whether the platform's cost still makes sense. If you have no skill to build on yet, our guide to making money online with no experience is a better first step.

Who this suits, and who it doesn't

These tools suit people who already have something to sell or a clear design idea, want a low-cost way to test it and accept that the hard part is finding buyers. They are a poor fit for anyone hoping software will produce income without an offer or an audience.
