How to Sell Software and SaaS Products
Software Business Models
SaaS (Subscription Software)
SaaS products are hosted online and accessed through a web browser. Customers pay monthly or annually for access, and the software runs on your servers rather than the customer's device. This model generates predictable monthly recurring revenue (MRR) that compounds as new customers join. The key metric is MRR growth: if you add more monthly revenue from new customers than you lose from cancellations (churn), your revenue grows every month automatically. Examples include project management tools, email marketing platforms, analytics dashboards, and any browser-based business tool.
SaaS requires ongoing infrastructure costs (hosting, bandwidth, support) that scale with your customer base, but these costs are typically 10% to 20% of revenue at healthy scale. Gross margins of 80% to 90% are standard for mature SaaS businesses, making this the most profitable software model for companies that achieve product-market fit.
One-Time Purchase Software
Desktop applications, mobile apps, WordPress plugins, and downloadable tools sold for a one-time fee generate immediate revenue without the complexity of subscription billing. The tradeoff is no recurring revenue: each month's income depends entirely on new sales. Many one-time purchase software products add optional annual support and update subscriptions to create a recurring revenue component. A WordPress plugin might sell for $49 with the first year of updates included, then charge $19 per year for continued updates and support.
Freemium
Freemium offers a limited version for free and charges for premium features. This model works when the free version demonstrates clear value and the premium features solve a pain point significant enough to justify payment. Conversion rates from free to paid typically range from 2% to 5%, which means you need a large free user base to generate meaningful revenue. Freemium works best for products with viral potential (users invite other users) or strong network effects (the product becomes more valuable as more people use it).
Marketplace Apps
Building apps for existing platforms (Shopify App Store, WordPress plugin directory, Chrome Web Store, Salesforce AppExchange) gives you access to built-in distribution. The platform's marketplace sends potential customers to your listing based on search and category browsing. Marketplace commissions range from 15% to 30% of revenue, but the traffic can be worth the cost. Shopify apps are a particularly strong category because Shopify's 4 million merchants actively search for apps to extend their stores, and the average merchant installs 6 to 8 apps.
Building Your First Software Product
Start with a problem you understand deeply, ideally one you have experienced yourself. The most successful indie software products solve specific pain points for specific audiences. A spreadsheet that took you 10 hours to build every month becomes a SaaS tool that automates the same process. A workflow you cobbled together with 5 different tools becomes a single integrated product. The closer you are to the problem, the better your solution will be.
Build the minimum viable product (MVP) first. The smallest version that solves the core problem for your target user is enough to launch, charge money, and start collecting feedback. A project management tool does not need Gantt charts, time tracking, resource allocation, and integrations on day one. It needs task lists and basic organization. Ship fast, charge from day one, and iterate based on what paying customers actually request.
Technology choices matter less than shipping speed for most indie software. Use the language and framework you know best. Ruby on Rails, Django, Laravel, Next.js, or any modern web framework can power a SaaS product serving thousands of customers. Do not spend months evaluating technology stacks. Pick one, build, and launch. You can always rewrite or optimize later if the product succeeds and the technology becomes a bottleneck.
If you cannot code, you have two paths. No-code tools (Bubble, Softr, Glide) let you build functional web apps without programming, though they have limitations in customization and performance. Alternatively, hire a freelance developer on Upwork or Toptal to build your MVP. A simple SaaS MVP costs $5,000 to $20,000 to develop with a freelancer, which is a significant investment but recoverable within months if the product finds paying customers.
Pricing Software Products
SaaS pricing follows a tiered model with 3 to 4 plans. The most common structure: a starter plan at $9 to $29 per month for individuals and small teams, a professional plan at $29 to $99 per month with more features and higher usage limits, and a business or enterprise plan at $99 to $499 per month with advanced features, priority support, and team management. Most customers cluster around the middle tier, which should be your target revenue anchor.
Annual billing with a discount (typically 2 months free, so "pay for 10 months, get 12") improves cash flow and reduces churn. Annual customers are less likely to cancel because they have made a larger upfront commitment. Offering both monthly and annual options lets customers choose their preference while incentivizing the annual plan.
For one-time purchase software, price based on the value of the problem solved rather than the complexity of the code. A simple WordPress plugin that saves a store owner 5 hours per week is worth $99 regardless of whether it took you 20 hours or 200 hours to build. Include one year of updates and support in the purchase price, then offer annual renewal at 30% to 50% of the original price for continued updates.
Free trials convert better than free tiers for most SaaS products. A 14-day free trial (no credit card required) lets potential customers experience the full product before committing. Conversion rates from free trial to paid typically range from 5% to 15%, significantly higher than freemium conversion rates of 2% to 5%. Require a credit card for the trial if you want higher-quality signups who are more likely to convert, at the cost of lower total trial signups.
Distribution and Sales Channels
Your own website is the primary sales channel for SaaS products. Build a clear landing page that explains what the product does, who it is for, and why it is better than alternatives. Include pricing, a free trial signup button, customer testimonials, and a product demo (video or interactive). The landing page is your salesperson, and it needs to answer every question a potential buyer might have.
Marketplace distribution (Shopify App Store, WordPress.org, Chrome Web Store) provides built-in traffic from platform users actively searching for solutions. Listing on a marketplace requires meeting the platform's review and quality standards, which takes 1 to 4 weeks for approval. Marketplace fees (15% to 30%) are significant but justified by the traffic and credibility they provide. Many successful software sellers use marketplaces for customer acquisition and then migrate high-value customers to direct billing.
Content marketing and SEO are the most cost-effective long-term acquisition channels for software. Write blog posts targeting keywords your potential customers search ("best invoicing tool for freelancers," "how to automate inventory management"). Each ranking blog post sends free traffic to your product indefinitely. Documentation, tutorials, and comparison pages ("Your Product vs Competitor") all contribute to SEO visibility.
Product Hunt launches generate a spike of early adopters for new software products. A successful Product Hunt launch (top 5 of the day) can generate 500 to 5,000 signups in a single day. The traffic is temporary, but the early adopters become your first paying customers, beta testers, and evangelists. Plan your Product Hunt launch carefully: have your landing page, onboarding, and support ready for a flood of simultaneous users.
Subscription Billing and Payment Processing
Stripe is the standard payment processor for SaaS, supporting subscription billing, usage-based billing, free trials, coupon codes, and invoice generation through its API. Stripe Billing manages the full subscription lifecycle: trial periods, plan changes, failed payment retries, and cancellation. Stripe charges 2.9% plus $0.30 per transaction with no monthly fees.
Paddle and FastSpring are merchant-of-record services that handle global tax compliance (VAT, GST, sales tax) on your behalf. Instead of collecting and remitting taxes in every jurisdiction yourself, you sell through Paddle or FastSpring, and they handle all tax obligations. This is particularly valuable for software sold internationally, where tax compliance across dozens of countries would otherwise require dedicated accounting resources. Paddle charges 5% plus $0.50 per transaction, higher than Stripe but inclusive of tax handling.
Dunning management (handling failed payments) is critical for subscription businesses. Credit cards expire, spending limits are reached, and bank accounts get closed. Without automatic retry logic, you lose paying customers to involuntary churn. Stripe automatically retries failed payments on a configurable schedule. Tools like Baremetrics Recover and Churnkey send customized emails to customers with failing payments, recovering 10% to 30% of otherwise lost revenue.
Reducing Churn
Churn (the percentage of customers who cancel each month) is the most important metric in a subscription business. A 5% monthly churn rate means you lose half your customers every year and need to constantly replace them. A 2% monthly churn rate means customers stay for an average of 4 years, making each customer worth 2.5 times more in lifetime revenue.
Reduce churn by improving onboarding (customers who reach an "aha moment" within the first week are far less likely to cancel), sending usage-based emails (nudge inactive users before they decide to cancel), collecting cancellation reasons (exit surveys identify fixable problems), and continuously improving the product based on customer feedback. Many SaaS products see the highest churn in the first 30 days, which means the onboarding experience has the biggest impact on retention.
Scaling a Software Business
Software scales differently than other digital products. Revenue growth comes from acquiring new customers, expanding existing customers to higher plans (upselling), and reducing churn. The magic of SaaS economics is that recurring revenue compounds: if you add $5,000 in new MRR and lose $2,000 in churn each month, your MRR grows by $3,000 per month, reaching $36,000 in additional annual revenue from just one year of net growth.
Hiring support and success staff becomes necessary once you pass 200 to 500 customers. Customer support for software is more complex than for other digital products because users encounter bugs, need help with integrations, and require guidance on features. Investing in documentation, knowledge bases, and in-app guidance reduces support volume per customer, but human support remains essential for retaining paying customers.
Software businesses are the most valuable digital product businesses for acquisition. SaaS companies typically sell for 3 to 10 times annual recurring revenue, meaning a product generating $100,000 per year in ARR could sell for $300,000 to $1,000,000. Marketplaces like MicroAcquire, Flippa, and FE International broker acquisitions for indie SaaS businesses.
