Most mid-size businesses don't need SAP or Oracle. They need software built around how their business actually works - not a platform that forces them to change their processes to fit a template. Topcone builds custom ERP systems for businesses with $5M-$50M in revenue and 20-100 employees who have outgrown QuickBooks, generic SaaS tools, or a patchwork of disconnected systems.
You've Outgrown Your Software. You Haven't Outgrown Your Options.
There's a gap in the market that most software vendors ignore.
Enterprise platforms like SAP and NetSuite are built for companies with hundreds of employees and IT departments to manage them. Entry-level SaaS tools like QuickBooks or HubSpot were never designed to run a complex, growing operation.
Mid-size businesses - $5M to $50M in revenue, 20 to 100 people - sit in the middle. Too big for simple tools. Too lean for enterprise complexity.
Custom ERP fills that gap precisely.
What We Build for Mid-Size Businesses
Every Topcone ERP system is different because every business is different. But the problems we solve tend to look familiar:
Disconnected systems - your accounting software, inventory, CRM, and operations tools don't talk to each other. Data gets re-entered, errors compound, and nobody has a single clear picture of the business.
Owner dependency - too much lives in one person's head or one person's spreadsheet. The business can't scale because it can't run without the owner in the middle of everything.
Workarounds as standard practice - your team has built informal processes around the gaps in your software. These workarounds work until they don't - and when they fail, it's expensive.
Reporting that lags reality - by the time you have the numbers, the moment to act has passed. Decisions get made on gut feel because the data isn't accessible or trustworthy.
Software that can't grow with you - every time the business evolves, the software becomes a bottleneck rather than an enabler.
How Topcone Approaches Custom ERP
We don't start with technology. We start with how your business actually runs.
That means spending time understanding your workflows, your exceptions, your team, and your goals - before writing a single line of code.
The result is software that mirrors your real operations, not a generic best practice that someone else decided works for businesses like yours.
Our process:
1. Discovery - We map how your business currently operates, where the friction is, and what a better system would look like in practice.
2. Design - We design the system around your workflows, not the other way around. You review and approve before anything is built.
3. Build - We build in phases so you see progress and can give input along the way. No big-bang launches that disrupt operations.
4. Transition - We move you from your old system carefully, with parallel running where needed, so nothing falls through the cracks.
5. Support - The system evolves with your business. We stay involved.
Is Custom ERP Right for Your Business?
Custom ERP is not for everyone. It requires investment, time, and a clear understanding of your own processes.
It tends to be the right move when:
- Your SaaS licensing costs are climbing past $5,000-$10,000 per month
- You have processes that no off-the-shelf tool can handle without major workarounds
- Growth has stalled because your systems can't keep up
- You are spending more time managing software than running the business
- Key decisions depend on one person because data isn't accessible to the team
If several of these resonate, a conversation is probably worth having.

Frequently Asked Questions
How much does custom ERP cost for a mid-size business?
Custom ERP projects for businesses in the $5M-$50M revenue range typically start from $25,000 and scale based on complexity, number of users, and integrations required. Unlike SaaS, it is a one-time build - not an ongoing monthly fee that compounds over time.
How long does it take to build a custom ERP system?
Most projects for mid-size businesses take between 3 and 9 months depending on scope. We build in phases so your business sees working software early in the process rather than waiting for a single large delivery.
Will we have to change how we work to fit the new system?
No. That is the core difference between custom ERP and off-the-shelf software. We build the system around how your business already works, not how a software vendor thinks you should work.
Can you replace our existing system without disrupting operations?
Yes. We plan transitions carefully, often running old and new systems in parallel during handover, to make sure nothing is lost and the team is confident before the old system is retired
Do you work with businesses outside Los Angeles?
Yes. While we are based in Los Angeles, we work with businesses across the United States. Most of our engagement happens remotely with periodic on-site visits where needed.
