A case study from RushKar Technology
This is one of the messages that we received a couple of months ago, sent to us by a manufacturing company locally in the Midwest. They had more than 10 years of existence, and they were doing decent business and developing annually. However, their email tone was very evident that they were overloaded.
They did not want a new application or a patch to their existing ones. They were asking for help.
“We’ve outgrown our tools. Everything takes too long. We don’t have visibility into our own operations anymore.”
That was their operations manager. And when we were finally on a call with their leadership team, it became obvious to us: their systems weren’t only outdated, but preventing the whole company from becoming more efficient.
They needed a custom ERP system. Not only because they wanted to become more modern, but because they wanted to grow without repeatedly fighting fires.
What Was Going Wrong?
Here’s the thing: this company didn’t fail. They succeeded, and fast. However they, like many businesses with rapid growth, had not upgraded the backend systems behind the daily working.
Each department used its own tools. HR had one software. Finance had another. Inventory management was only done with Excel files being shared by emails. Sales had no knowledge as to what was on stock and production had to check every detail twice before sending.
The result? Constant miscommunication. Inventory mismatches. Delays in payroll. Missed follow-ups with leads. And worst of all: no one had real-time data.
Why Off-the-Shelf ERPs Didn’t Work
The company had tried demoing two popular ERP platforms. They weren’t bad products, but they didn’t fit.
For starters, the price per user was too high. However, what is more important is that these systems imposed a certain change on how the company operated so that they got to adapt to the logic of the software.
They did not require a system that would redefine their workflows, but one that could reflect their workflows.
This is the reason they came to RushKar Technologies, a custom software development company that creates systems that are designed based on the actual operations of our clients.
Step One: Understanding the Business First
We had gone into their processes before writing a line of code.
We interviewed every department, HR, finance, warehouse, production, sales and asked many questions.
- What slows you down?
- What’s your current process?
- Where do mistakes happen?
- What do you wish worked better?
This wasn’t just “requirements gathering". It was us taking a temporary membership of their company so as to experience the friction spots first hand.
Building a Custom ERP: What We Delivered
Following the study, we came up with a custom software solution in the form of an ERP that impacted all major operations of the company. Nor was it an all-in-one monolith, but a collection of linked tools that would share information between themselves and communicate with one another.
Here’s what we built:
Inventory Management
Their biggest pain point. We created a system that tracked:
- Real-time stock levels across multiple warehouses
- Incoming and outgoing materials
- Low-stock alerts
- Purchase order history
- Barcode integration for faster check-ins/check-outs
Now, warehouse leads don’t have to guess. They just check the dashboard.
HR + Payroll
Their HR team had been juggling spreadsheets for attendance, leave, and salary calculations. We gave them:
- Employee profiles with digital records
- Leave requests with approvals
- Biometric attendance integration
- Auto-calculated salaries with tax rules baked in
No more manual errors. No more end-of-month crunch.
Finance
We connected HR, inventory, and operations to a central finance module that handled:
- Vendor payments
- Staff salaries
- Budget forecasts
- Expense tracking
- Invoice generation
- Custom financial reports for leadership
With everything in one place, the finance team had actual oversight. Not after-the-fact cleanup.
CRM + Sales Tools
Sales reps didn’t know what was in stock before quoting customers. That led to broken promises and delays. We fixed that with:
- A lightweight CRM integrated with inventory
- Lead tracking
- Quotation generation
- Follow-up reminders
- Sales history per client
When sales could see what was available, they closed more deals—and made fewer mistakes.
Role-Based Dashboards
Every department got its own dashboard:
- Warehouse managers saw movement logs and reorder alerts
- HR tracked attendance and upcoming reviews
- Sales saw active leads and quote-to-order ratios
- Finance monitored burn rate and monthly cash flow
Everything was designed to reduce friction and increase clarity.
The Tech Behind It
We kept the stack modern, scalable, and stable:
- Backend: .NET Core (fast, secure, and ideal for enterprise apps)
- Frontend: Angular (for smooth, dynamic user experiences)
- Database: SQL Server (robust reporting and integrations)
- Cloud: Azure (auto-scaling and easy backups)
Our developers integrated everything with APIs so that future upgrades or modules could slot in cleanly without touching the whole system.
The Results
The client started using the ERP in phases. First inventory. Then HR. Then sales and finance.
Here’s what changed within the first three months:
-
Inventory accuracy improved by 80%
Stockouts and over-ordering dropped. They could finally trust the numbers.
-
HR saved 20+ hours a month
Automated attendance and payroll meant fewer mistakes and no more manual entry.
They had live stock data and could quote confidently.
-
Finance ran cleaner reports
They weren’t patching together Excel sheets. Everything flowed from real-time inputs.
It feels like we’re finally running a modern company,” the operations head told us.
Everything’s smoother. Fewer fires. We can plan instead of react.
Why This Matters (And Why Custom Still Wins)
In 2025, it’s tempting to think you need a SaaS subscription for everything. But for a growing business, custom software still has real value:
- You’re not paying monthly license fees forever
- You don’t have to adapt your workflow to someone else’s product
- You can start small and expand as you grow
- You own your platform, not just rent it
Yes, it’s an investment. But when done right, it pays for itself in efficiency and peace of mind.
