The Setup Nobody Talks About
Most people skip straight to building when they hear about SaaS, which is backwards. Before you write a single line of code, you need to figure out who actually has the problem you're solving, what they're currently using to deal with it, and—this is the part everyone forgets—whether they're willing to pay for a better solution. I spent three months before my first launch talking to potential customers instead of coding. Three months of phone calls and coffee meetings. Not one feature was built until I'd confirmed that at least seven people said they'd actually open their wallet for what I was describing. The math is simple: if you can't get someone to commit money before they've seen anything, you won't get money after they see it either. Pick something narrow to start with. "Marketing automation for everyone" is a death sentence. "Automated follow-up sequences for small dental practices" is a business. You pick the narrow market because it tells you exactly who to talk to, what features actually matter, and where to find them without spending a fortune on ads.
Pick the Stack and Build Ugly
Here's the thing nobody wants to admit: your initial stack doesn't matter nearly as much as you think it does, but it does matter enough to not screw yourself over completely. Pick something you already know how to use. A lot of founders start with whatever's trendy, then spend six months fighting with frameworks they don't understand when they should be talking to customers. I went with Next.js on the front end, Supabase for the database and auth, and Stripe for payments because that combination gets you running in days, not weeks. The auth piece alone will save you from security headaches that take months to debug later. For the MVP, keep it ruthlessly simple—just the core feature, a signup flow, a login, and Stripe integration. No analytics dashboard, no referral system, no community features. If users aren't paying for the core function, adding extras won't fix that. When you actually launch, there's a weird edge case worth knowing about: during Stripe setup, you need to handle webhook verification before the rest of your app works properly. I learned this the hard way when subscription cancellations kept happening silently while the UI still showed active subscriptions. The problem was my webhook handler wasn't verifying the Stripe signature, so it was accepting forged requests. Once I added proper verification, those phantom cancellations stopped immediately. It took about two hours to fix but caused me about three weeks of confused debugging.
Pricing and the First Paying Customer
Now, let's talk about pricing, which most founders get wrong because they're either too scared to charge or too greedy. You want to find that middle ground where people actually pay without feeling like they're being robbed. The trick is charging based on the value you're delivering, not what it costs you to provide it. Most B2B SaaS products land somewhere between $29 and $299 monthly depending on who's buying. If you're targeting small businesses, stay under $100. Enterprise buyers won't blink at higher prices, but they also demand way more support and customization. There's a counter-intuitive thing about pricing: offering a paid plan alongside a free tier usually converts better than just a free trial with no paid option. People take free trials way more seriously when there's an actual price tag on the alternative. I've seen free trial-to-paid conversion rates jump from 3% to 12% just by adding a $1/month plan that gives limited access. The presence of a paid tier makes the free version feel like it has boundaries, which makes the upgrade path feel necessary instead of optional. The catch with free trials is your customer acquisition costs probably aren't covered in the trial period, especially on cheaper plans. So your goal is getting that activation rate above 40%—meaning 40% of signups actually use the core feature at least once. Below that number, you're basically giving away product to people who'll never convert.

: it's not about the code or the product, it's about finding a group of people who already feel the pain, building the minimum thing that fixes it, and charging them before you build anything fancy. Start narrow, charge early, and don't add features until paying customers ask for them. Everything else is noise. The biggest mistake people make is building for too long before talking to anyone who might pay. The second biggest is launching something too complex that requires a tutorial to understand. Your first version should be embarrassingly simple. If someone can't figure out the main action in 30 seconds, you've overbuilt it. Don't worry about perfecting the landing page copy in week one. Worry about getting ten people to use the product and telling you what's broken. Ten bad reviews teach you more than a thousand page views from people who never signed up.What I Wish Someone Had Told Me
