Custom Software Success Stories: The RockitSeller Story
In the ever-changing eCommerce space, innovation doesn’t happen – it’s created. At Kahnputers, we don’t just build software. We craft revolutions.
One of our highest testimonies to that is RockitSeller: an end-to-end eCommerce automation platform that evolved from a bold idea to a revenue-driving SaaS success. This is not just a case study – it’s a guide for turning complexity into growth.
The Vision: A Better Backend for Online Sellers
RockitSeller was born in 2020 out of necessity. Sellers were drowning online. Adding products across multiple channels, managing inventory, syncing prices, handling FBA logistics, and running ads – all in one place – felt like balancing burning swords… blindfolded.
The founder’s vision was straightforward yet powerful:
“What if we could build the multichannel backend sellers would ever dream of?”
That question gave rise to a strategic buildout of integrated tools – each solving a fundamental pain point:
-
Sellwise – Omnichannel inventory sync and product listing
-
Pricewise – Real-time repricing automation
-
Adstein – PPC optimizer native to Amazon
-
Bookwise – Book product research for bookstores
-
Listwise – Listing optimization using AI
-
Searchwise – Walmart product research and opportunity scoring
Each of these tools needed to function on its own and operate as a suite. The real challenge wasn’t building features – it was developing a system sellers could trust.
The Build: Scalable SaaS from Scratch
Our task at Kahnputers was to implement that vision with scalable architecture and robust infrastructure. We made foundational choices from day one:
-
Cloud-first infrastructure: AWS Lightsail + RDS for cost-effective scale
-
Microservice-ready backend: .NET Core APIs orchestrated with SQS and EventBridge
-
Modern frontend: React + MUI + Chart.js for fast, responsive dashboards
-
AI integrations: Microsoft ML, Stable Diffusion, and Claude for automation intelligence
-
Stripe + GoHighLevel: For billing, user onboarding, and CRM workflows
-
Zapier + n8n: For internal ops and marketing automations
-
Pixel-ready funnels: Built using Divi and GoHighLevel for ad tracking & conversion
This wasn’t just code – this was choreography.
We called it the Automation Waltz: every system dancing in sync, reacting in real-time to pricing updates, inventory shifts, and ad performance.
Iteration in Action: MVP to Ecosystem
We stuck to a tight build-measure-learn loop to move fast and stay aligned with user pain points:
âś… Sellwise MVP shipped in 90 days
âś… Pricewise and Adstein added based on direct seller feedback
âś… Chrome extension built for one-click research workflows
✅ Listwise and Searchwise powered by RockitSeller’s native AI models
âś… BIAB training portal launched to onboard and convert new users
All features were built for scale:
-
Stateless APIs enabling horizontal scaling
-
Shared tokenized authentication
-
Feature-flag toggles for safe updates
-
Daily uptime dashboards and health checks
-
Multitenant support for agencies managing multiple sellers
Chaos to Control: What Changed for Users
Before RockitSeller, sellers were manually listing on Amazon, eBay, Shopify, Newegg, Etsy, and TikTok – making wild guesses about pricing and ad performance.
After RockitSeller:
-
Listings sync to all marketplaces from one dashboard
-
Pricing adapts to market trends with AI-driven rules
-
Real-time SKU-level profitability becomes visible
-
Retargeting and email tracking built right in
-
Sellers can run simulations to forecast ad returns or inventory gaps
“I used to spend time looking at five dashboards a day. Now I just log into RockitSeller and I know what to do.”
Why RockitSeller Succeeded
Three reasons this SaaS platform scaled when most fail:
1. Founder-led Product Insight
The founder was a seller first. He didn’t guess – he built what he knew was needed from experience.
2. Change-Tolerant Tech Stack
From pricing to listings, every part of the platform was modular, testable, and deployable without breaking the whole system.
3. Community Feedback Loop
From Bookwise beta testers to BIAB coaching groups, user feedback fueled the product roadmap every step of the way.
The Outcome: A Growth-Driving Platform
As of 2025, RockitSeller has:
-
Helped over 1,200 sellers scale multichannel
-
Managed over $40M in seller revenue
-
Launched successful product releases with data-informed pricing
-
Built a thriving agency partner program
-
Released the Automation Vault so sellers can replicate workflows in one click
But more than metrics – it gave sellers control over their chaos. It turned reactive hustle into proactive strategy.
