Our Client Success Case: A Custom Real Estate ERP that Reduced Administrative Workloads by 30%

Our client is a mid-sized real estate agency that we helped simplify and supercharge their business management. They had been juggling separate systems for properties, client relationships, and finances, which created data silos and made it pretty tough to get things done on time. So, we built a custom ERP system that brought everything under one roof.

Core Features of Our Custom ERP Solution

You can overview your whole business or focus on specific parts. For example, check how you handle money, make things cheaper, boost customer satisfaction, partner better, adapt processes for M&A, or ensure compliance.

After exploring processes, team preferences, and pain points, we zeroed in on the areas that mattered most to our client: building stronger customer relationships with faster, better service; sharpening financial management to give owners clearer budget control; and ramping up automation. With these goals front and center, we decided on and crafted the following features and modules:

1. Property Management Module: We created a centralized database, where all property listings, tenant details, and maintenance requests are in one place. We also added tools for tracking lease agreements, renewals, and compliance, so they never miss an update or risk any legal snags.

2. Customer Relationship Management: The CRM system now keeps all client interactions and sales leads together. Automated communication tools handle follow-ups and reminders, boosting client engagement and conversion rates.

3. Financial Management: To simplify operations, we integrated budgeting, forecasting, and financial reporting into a single system. We also included real-time dashboards that offer a snapshot of financial performance. 

4. Analytics and Reporting: Customizable reporting tools allow for the generation of reports on sales trends, client activity, and finances, while real-time analytics help teams get clear, quick insights and make informed calls.

5. Workflow Automation: Routine tasks like tenant communication and maintenance scheduling now run automatically, freeing up staff time. Plus, integration with their existing software creates smooth data flow.

6. Document Management System: Our team implemented a secure, organized document storage solution, so all contracts, compliance records, and paperwork are easy to find and protected. Also, we added e-signature capabilities to let clients approve documents quickly, reducing turnaround times.

7. Scalability and Customization: To future-proof our client’s operations, we built the system with a scalable architecture that grows alongside their business – they can tailor fields, forms, and reports to fit changing needs.

Project Outcomes

The solution we developed made a substantial difference for our client, from how they now shape their business development strategy to the way client interactions are managed. In terms of numbers, we’ve achieved:

• 30% reduction in admin work: Automating routine tasks took a huge load off the team, saving around 500 hours each month in manual work.

• 40% faster data retrieval: With all data centralized, the team can now access information more quickly and with 98% accuracy, cutting down on search times and errors.

• 25% increase in client satisfaction: The improved CRM has made client interactions more organized, and feedback from clients showed a 25% rise in satisfaction, with 90% saying they’re happier with the company’s services.

Custom Real Estate ERP Development Process for Our Client

When you run a company with multiple departments, you know better than anyone how critical a well-tailored ERP system is. After all, it touches everyone—from finance to HR, sales to supply chain. To make sure it’s worth the investment, it has to meet the needs of all your employees across the board. That’s why we start every ERP project with a discovery phase.

“We always begin by talking with the main stakeholders to understand their operations, challenges, and needs. We use surveys, interviews, and as many conversations as possible to get a sense of tech skills and day-to-day tasks across teams. Our goal isn’t just to build a working system; it’s to create one that truly makes everyone’s work easier, helping save time, money, and resources company-wide.”

— explains the Head of Delivery at Inoxoft, Maksym Trostyanchuk.

Step 1: Design and Prototyping 

Once we gathered the requirements, we set out to build an initial prototype for the ERP system, covering all the core features. But like any complex project, we ran into some challenges. Here’s how we tackled each one:

Challenge #1 API limitations

Some of the third-party tools we needed to connect had outdated or restricted APIs, which made data flow a bit tricky.

•  Our solution: To work around these API issues, we focused on building each module (like property management, CRM, and financials) separately. That’s helped us pinpoint any API-related challenges and find workarounds to be sure each part worked well before we brought it all together.

Challenge #2 Data synchronization

Keeping data synced up in real-time across different systems was critical for accuracy. Even the slightest delay could lead to mismatches and confusion.

•  Our solution: We held workshops with both IT and business teams to map out how data would flow from the legacy systems to the new ERP. Together we created a plan for real-time updates and found all the weak points that could disrupt synchronization.

Challenge #3 Varied user roles

The system had to work for a lot of employees – agents, property managers, marketing teams – each with their own workflows and must-have features, like mobile integration for agents, or advanced statistics for accountants.

•  Our solution: Our team created user personas for each role to make the ERP feel natural for everyone. Also, with each prototype, we gathered feedback from actual end-users through surveys and focus groups. They told us what worked well, what didn’t, and how we could make the system easier and more intuitive.

Step 2: Development

We built the ERP system in agile sprints, which let us stay flexible and adjust as needed along the way. But as development got underway, some challenges popped up that called for creative solutions.

Challenge: New feature requests

Quite expectedly, once we started coding, stakeholders from different departments began asking for extra features that hadn’t been in our original plan. 

The sales team, for example, as we worked on the CRM module, requested analytics for customer behavior. Of course, these ideas could add real value, but every new feature meant more time and effort for design, development, testing, and integration—and our timeline started feeling the squeeze.

•  Our solution: We wanted to manage these requests without slowing the project down, so we used an Impact vs. Effort Matrix – a simple tool that let us and the stakeholders weigh each new request by its business impact versus the time and resources needed. Here’s how the project’s team lead explained this approach:

“We sorted requests into four categories to keep things clear and manageable. First, we had ‘Quick Wins’—high-impact features that didn’t take much effort, so we fast-tracked these for quick delivery.

Then there were ‘Major Projects,’ which had big potential but needed a lot of resources. We decided to deal with those in later sprints, after the quick wins.

We also had ‘Fill-Ins’—small, low-impact features we could address if we had spare time.

And finally, ‘Time Sinks,’ which were low-impact and high-effort, so we deprioritized them or set them aside altogether. Plus, with regular meetings to review these requests together, stakeholders stayed informed, and decisions were clear and fair.”

Here’s a quick look at the matrix we used for the task:

Step 3: Testing and Quality Assurance

After a long and sometimes challenging development phase, we finally proceeded with testing and took it very seriously. With so many components, user roles, and custom features, we simply couldn’t afford any bugs—we had to make sure every module worked perfectly and met our quality standards. Of course, there were some challenges that we had to deal with:

Challenge #1 Finding bugs in complex integrations

As we’ve mentioned, with so many systems tied together, it wasn’t easy to spot every bug right away, so our team had to develop a more complex and sophisticated QA strategy. 

•  Our solution: Our QA team built a detailed testing plan that covered every angle of the system. First, we ran unit tests to catch any issues within individual components. Then, we moved to integration tests to make sure all the parts worked well together. For real-world validation, user acceptance testing (UAT)  was set up to see how the system performed for actual users. 

Also, to speed things up, we used automation wherever possible, including automated scripts for repetitive tests and continuous integration pipelines to quickly catch issues when adding new code. 

Challenge #2 User Acceptance Testing (UAT) involvement

For a company with many departments, it was challenging to get all the key users to join UAT sessions due to their tight schedules.

•  Our solution: To involve more users, we scheduled UAT sessions at different times so everyone could join and provide feedback. It took some coordination, but by working closely with the HR department, we got it right. This kept the testing process smooth and made sure the final system meets everyone’s needs.

Step 4: Deployment

In the final stages, we switched from the old systems to the new ERP, keeping any disruptions to a minimum. A key and most important part of the deployment was data migration, where we had to ensure information was transferred cleanly and accurately. To do this, we created a detailed data mapping plan—here’s how it worked:

•  Data inventory assessment. Together with the client’s IT team, we reviewed all their data, identified all important elements, spotted any issues, and clarified any problems. We wanted a seamless experience, and that starts with knowing every data source like the back of our hand.

•  Building mapping templates. Then, we detailed exactly how data from the old system matched up with fields in the new ERP. We set rules for things like dates, standardized values, and marked fields needing cleaning or updates.

•  Rigorous validation checks post-migration. Finally, our team cross-checked samples from both systems, verifying that everything matched up. This way, all data in the new ERP was accurate and ready to go.

“Data migration isn’t just about transferring information; it’s about making sure the new system works right from the get-go. When we map and check everything carefully, it means the new ERP can do its job without any surprises, giving our clients the confidence they need to hit the ground running.”

– adds our data specialist.

Step 5: Post-Deployment Support

As the business expanded, so did our client’s need for new features and changes to the system. We set up a feedback system where users could report problems or suggest improvements, helping us address the most important updates based on real user input.

“Our feedback system is built to be both easy to use and powerful. Users can quickly send in issues or feature requests through a simple platform that’s connected straight to our process. This means we can review feedback immediately, prioritize what matters most, and make changes right away or during regular updates.”

– explained our lead developer.

Insights Learnt from the Case

When it comes to big decisions like adding an ERP system to your business, it’s easy to feel like you’re stepping into uncharted territory. But here’s the good news: we’ve done the homework, faced the challenges, and picked up some gold nuggets of wisdom along the way. So, instead of learning the hard way, you can take a shortcut with our real-life insights.

1. Conduct a Thorough Needs Assessment

First things first: know what you need. Get everyone—sales, property management, finance—around the table and dig into what works, what doesn’t, and what just plain annoys them. Use workshops, one-on-one interviews, and surveys to capture honest feedback and different perspectives. Shadow teams for a day to see the workflow in action and pick up on pain points that might not come up in conversation.

If you skip this step, you’re setting yourself up for some serious “I wish we knew that before” moments. Lay out your workflows and spot the gaps your ERP needs to fill.

“It’s a nightmare to find out too late that your shiny new ERP doesn’t actually meet half the team’s needs. Trust me, gathering input from day one saves headaches and keeps everyone on board.”

– says our senior business analyst.

2. Focus on Automation

Think about those mundane, repetitive tasks that eat up time—like manually entering data or compiling reports. These are prime candidates for automation. Freeing up your team from these chores not only cuts down on mistakes but also gives them back valuable hours to focus on more strategic projects. Plus, automated workflows between departments mean fewer emails flying back and forth and faster, smoother communication.

“Once we automated our core processes, it was like flipping a switch. Suddenly, people weren’t drowning in busywork anymore and we could actually get creative, attracting more customers.”

– shares one satisfied client in real estate we worked with.

3. Plan for Scalability

Your ERP should be a solution that grows with your business, not a roadblock to future success. It should be flexible enough to incorporate new features, technologies, or modules as your company expands and adapt to shifts in market conditions or regulatory changes. The last thing you want is to be stuck with a system that can’t keep pace when the market or regulations change. Our client shares his experience with ERP development:

“Our first ERP system was a nightmare when it came to flexibility. We had numerous delays and spent way too much on extra costs because of it. Basically, that was the main reason we turned to Inoxoft. Now, we have an ERP that is adaptable and ready for growth, so we don’t have to worry about technology at all. We can finally focus on new marketing strategies and lead generation, knowing the system will handle everything without any major issues.”

4. Monitor Performance Metrics

It’s one thing to set up an ERP, but it’s another to know if it’s actually pulling its weight. Decide upfront which KPIs will tell you whether things are getting better (e.g., less time spent on admin). Keep an eye on those numbers and do regular check-ins to make sure you’re on track or spot areas that need a little extra attention.

“Tracking KPIs wasn’t just helpful—it was eye-opening. We knew exactly where we were winning and what needed more attention, so we didn’t waste time guessing.”

– that’s how described it one of the project stakeholders.

So, there you have it. These lessons from the real world show that a well-thought-out ERP system isn’t just software—it’s a real strategic decision for making your operations smoother, your team happier, and your days a little less chaotic.

When Your Company Should Consider a Custom ERP System 

We get that custom solutions aren’t right for everyone. If you’re running a smaller real estate business, a fully tailored system might end up costing more than it’s really worth. In those cases, sticking with an out-of-the-box ERP and changing your processes a bit could be the smarter move. For larger companies, though, the story is different. As our COO, Nazar Kvartalnyi, puts it:

“Managing multiple processes like real estate deals, leasing, and finances is no small task. A standard system often can’t keep up with all these interconnected needs. That’s where a custom ERP really makes a difference—it’s designed to fit your exact needs, so you’re not constantly bending a generic system to make it work. And yes, custom development is a bigger upfront investment, but over time, it pays off with better efficiency and fewer workarounds.”

ERP Modules for Real Estate We Recommend Adding to Your Software

ERP isn’t just a simple system. As we’ve said, it’s built to support every department across a company, which means it has a lot of different parts working together to get the job done. In a 2023 survey of IT decision-makers, 76% said they’d heard of composable ERP, and out of those, 84% were planning to invest in it. That’s exactly what we did with our project—we built it piece by piece from different modules to create one powerful, unified system.

We also talked to our team of experts, who’ve worked on similar projects, to get their insights on what modules are the most useful in an ERP for real estate agents. Here’s what we can share with you:

Property and Facility Management Essentials

We recommend starting with strong property and facility management modules. These are at the core of any real estate operation. With organized maintenance requests, tenant updates, and other daily tasks in one place, you don’t have to worry about things getting lost in spreadsheets or notes. This setup saves time and lets managers focus on more important tasks.

Building Relationships with CRM and Sales Tools

Real estate is as much about people as it is about properties, which is why you should prioritize CRM and sales tools. With CRM, your team can stay in sync with clients and leads, making sure no important detail is missed. Sales and marketing tools also help you reach clients with more personalized offerings, empowering agents to work smarter and deepen client relationships for long-term success.

Lease, Finance, and Asset Management

Lease, finance, and asset management modules are true essentials for property managers. Lease management tracks renewals and agreements, finance management keeps numbers accurate, and asset management shows how each property is performing. Together, they give a clear view of every property’s status, making decisions easier.

Supporting Client Relationships with CRM and Sales Tools

Relationships matter as much as properties in real estate. That’s why we recommend adding CRM and sales tools to your software. CRM keeps your team on the same page with clients and leads, so you don’t miss important details or follow-ups. Sales and marketing tools help agents connect with clients in meaningful ways, making it easier to grow client relationships.

Organized Document Management

We know that real estate work involves a lot of documents, and keeping track of them can be overwhelming. We also know that the document management module keeps everything in one place, so agents don’t have to waste time digging for files or worry about using outdated versions. This frees up more time to focus on clients.

To Sum Up

Custom software development can seem like a lot of work, but when it’s done right, it’s exactly what businesses need to thrive. If custom ERP solutions weren’t worth it, the IT industry wouldn’t be where it is today. And while custom ERP might be costly upfront, it often saves money over time compared to off-the-shelf options. 

Plus, when you own your ERP, you get the added benefits of stronger data security and tools that truly match your industry’s needs. No surprise so many companies are choosing to build their own!
