Revenue Monitoring for Indie Hackers & Solo Founders

There is a particular kind of joy that indie hackers know well -- the sound of a sale coming in. That notification that someone, somewhere in the world, found your product valuable enough to pay for it. For solo founders building in public, bootstrapping side projects, or running small SaaS businesses, revenue is not just a metric -- it is validation. Every sale confirms that what you are building matters. And you deserve to know about every single one the moment it happens.

Revenue monitoring with Webhookify gives indie hackers and solo founders instant, real-time awareness of every sale, subscription, and payment across all their products. Connect Stripe, LemonSqueezy, Gumroad, or any payment platform, and the Webhookify mobile app plays a cash register sound every time money comes in. It is a simple feature with a profound psychological impact -- you are never more than a few seconds away from knowing your product just earned revenue.

The Challenge

Being a solo founder means wearing every hat. You are the developer, the marketer, the support team, and the CFO. Revenue monitoring often falls to the bottom of the priority list because there are so many other things demanding your attention.

You discover sales hours after they happen. You are deep in a coding session, or sleeping, or spending time with family, and a customer buys your product. You find out later when you open the Stripe dashboard or check your email. The moment has passed. The dopamine hit of a sale is diminished when you discover it alongside ten other events in a batch.

Multiple products mean multiple dashboards. Many indie hackers run two, three, or five products simultaneously -- a SaaS tool on Stripe, a course on Gumroad, a template on LemonSqueezy, a mobile app on RevenueCat. Checking each dashboard individually is time-consuming and easy to forget.

Failed payments slip through unnoticed. When you are the only person responsible for everything, a failed subscription renewal can go unnoticed for days. You do not have a customer success team watching for these. By the time you notice, the customer has churned and moved on.

MRR milestones pass without celebration. You have been working toward $1,000 MRR, or $5,000 MRR, and the milestone passes on a random Tuesday while you are grocery shopping. You find out three days later in your analytics dashboard. The moment of achievement deserves better than that.

The emotional isolation of solo building is real. Without a team to celebrate wins with, the psychological rewards of building a business can feel muted. Revenue notifications are more than just data -- they are moments of connection between your effort and its impact.

How Webhooks Solve This

Every payment platform used by indie hackers supports webhooks. Stripe, LemonSqueezy, Gumroad, Paddle, and RevenueCat all fire webhook events when payments are processed, subscriptions are created, and refunds are issued. These webhooks are the raw signal that revenue is flowing.

Webhookify captures these webhooks and transforms them into the experience indie hackers actually want: an instant, celebratory notification on their phone. The AI summarizes the payment details into a human-readable message -- "New sale: john@gmail.com purchased the Pro Plan for $29/month" -- and the mobile app plays the cash register sound. No dashboards to check. No emails to dig through. Just an immediate awareness of every dollar your products earn.

Setting It Up with Webhookify

1

Create Endpoints for Each Product

Log in to Webhookify and create a webhook endpoint for each product or payment platform you use:

  • "SaaS Product - Stripe" for your subscription SaaS
  • "Course Sales - Gumroad" for your digital products
  • "Templates - LemonSqueezy" for your marketplace products
  • "Mobile App - RevenueCat" for in-app purchases

Each endpoint gets a unique URL. Separate endpoints per product mean your event logs are organized and you can track revenue per product in your Webhookify dashboard.

2

Connect Your Payment Platforms

Add your Webhookify endpoint URLs to each payment platform:

Stripe: Go to Developers > Webhooks in your Stripe Dashboard. Add your Webhookify URL and select checkout.session.completed, invoice.paid, payment_intent.succeeded, customer.subscription.created, customer.subscription.deleted, and invoice.payment_failed. Our Stripe webhook setup guide walks through every step.

LemonSqueezy: Navigate to Settings > Webhooks in your LemonSqueezy dashboard. Add your Webhookify URL and enable events for order creation, subscription creation, subscription payment, and subscription cancellation. See our LemonSqueezy webhook guide for details.

Gumroad: In Settings > Advanced, scroll to the Webhooks section and paste your Webhookify URL. Gumroad sends webhooks for every sale automatically. The ping includes the product name, price, customer email, and purchase details.

RevenueCat: Go to Project Settings > Integrations > Webhooks. Add your Webhookify URL and enable events for initial purchase, renewal, cancellation, and billing issues. Check our RevenueCat webhook guide for the full setup.

Enable the Cash Sound on Mobile

This is the step that makes revenue monitoring magical. Download the Webhookify app from the App Store or Google Play and sign in with your account.

In the app settings, enable push notifications and toggle on the cash register sound for payment events. Now, every time a webhook from a payment platform hits your endpoint, your phone will play the satisfying ka-ching sound.

The cash sound works even when your phone is on silent if you configure it as a critical alert (available on iOS). This means you will hear your revenue coming in whether you are at your desk, walking the dog, or lying in bed at night.

Pair this with a smartwatch for the full experience -- revenue notifications on your wrist with a haptic tap that says "you just made money."

Set Up a Revenue Telegram Channel

Beyond the cash sound, create a Telegram channel or group that serves as your personal revenue feed. Connect it in your Webhookify notification settings.

Every sale, subscription, and payment will post to this channel with an AI-generated summary:

New Sale - SaaS Product
Customer: sarah@startup.com
Plan: Pro Monthly
Amount: $49.00
Source: Direct signup

---

New Sale - Course on Gumroad
Customer: developer@gmail.com
Product: Advanced API Design Course
Amount: $79.00

This Telegram channel becomes your revenue diary. Scroll through it at the end of the day to see everything you earned. Share it with a mastermind group or an accountability partner for motivation. Pin messages for milestone sales.

Real-World Scenarios

The Build-in-Public Revenue Stream

Priya is building a SaaS tool in public on Twitter. She has 8,000 followers who follow her journey from zero to profitability. Every time she makes a sale, Webhookify plays the cash sound on her phone and posts to her Telegram channel. She screenshots the notification and shares it on Twitter: "Just got my 100th customer! Ka-ching!" Her followers love the authenticity of real-time revenue updates, and the posts consistently get high engagement. The cash sound has become the soundtrack of her build-in-public journey.

Multi-Product Solo Founder

Marcus runs four products: a SaaS tool ($29/mo subscriptions via Stripe), a Notion template pack ($19 one-time via LemonSqueezy), a coding course ($99 via Gumroad), and a mobile utility app ($4.99 via RevenueCat). Before Webhookify, checking revenue meant opening four dashboards. Now, all four products feed into a single Telegram channel. On a typical day, he hears the cash sound four to eight times across all products. He knows immediately which products are performing and can adjust his marketing effort accordingly. When his SaaS gets three sales in an hour, he knows a blog post or tweet is resonating and doubles down.

Failed Payment Recovery for One-Person Teams

Lisa runs a solo SaaS with 150 subscribers. She connected Stripe's invoice.payment_failed events to Webhookify. When a payment fails, she receives an immediate push notification: "Payment failed for mike@company.com -- $39/mo -- Reason: Card expired." Lisa sends a quick personal email: "Hey Mike, looks like your card on file expired. Here is a link to update it. Let me know if you need anything!" The personal touch from a solo founder has a dramatically higher response rate than automated dunning emails. Lisa recovers 70% of failed payments with this approach, compared to 25% with Stripe's automated retries alone.

MRR Milestone Awareness

A solo founder has been tracking their MRR journey toward $5,000. They created a simple system: their Webhookify Telegram channel logs every payment, and they keep a running mental tally. On a Wednesday morning while making coffee, three cash sounds ring in quick succession -- $29, $49, $29. They open the Telegram channel, add up the recent subscriptions, and realize they just crossed $5,000 MRR. The moment is immediate and visceral. They celebrate right there in the kitchen. Without real-time alerts, this milestone would have been a number they noticed in their analytics dashboard three days later.

Best Practices

  1. Enable the cash sound and keep it on: This is not just a gimmick. The audible feedback of revenue creates a positive psychological loop that keeps you motivated during the hard parts of solo building. It is instant gratification for months of effort.

  2. Create a single revenue feed across all products: Even if you use separate Webhookify endpoints per product, route all payment success events to one Telegram channel or Slack DM. This unified feed gives you a complete picture of your earning activity without switching between dashboards.

  3. Monitor failed payments personally: As a solo founder, you cannot afford to lose customers to preventable payment failures. Set up failure alerts and respond personally within hours. Your personal attention is a competitive advantage that larger companies cannot match.

  4. Track refunds as a quality signal: Refund webhooks tell you when customers are unhappy enough to ask for their money back. A spike in refunds might indicate a product issue, a misleading marketing message, or a pricing problem. Monitor them alongside your sales.

  5. Share your revenue notifications: If you are building in public, your Webhookify alerts are content gold. Share screenshots of sales notifications, celebrate milestones, and let your audience feel the momentum of your business. Authenticity resonates.

  6. Use revenue alerts to inform marketing decisions: When you post a tweet, publish a blog post, or launch on Product Hunt, the cash sound tells you immediately if it is working. A cluster of sales right after publishing content gives you real-time feedback on what resonates with your audience.

Set up a "Monthly Revenue Review" ritual. At the end of each month, scroll through your Webhookify Telegram revenue channel and count your sales, note your biggest day, and identify which products performed best. This takes five minutes and gives you more actionable insight than any analytics dashboard because every entry is a real event with a real customer attached.
