I will build a custom CRM system for your business
Viacheslav M
About this gig
Tired of paying monthly for a CRM that doesn't fit your business?
HubSpot. Salesforce. Pipedrive. All built for someone else. You end up working around the tool instead of the tool working for you.
I build a CRM that fits your exact workflow.
You own it. No subscription. No vendor lock-in. Ever.
What you get:
- Modules built around your process contacts, deals, tasks, whatever you need
- Role-based access everyone sees what they should
- Full source code yours to keep, extend, or hand to any developer
20+ years in .NET and enterprise systems. One payment. One delivery.
Message me before ordering I'll confirm your requirements fit within 24 hours.

You get clean maintainable code, secure infrastructure, and direct communication with the developer writing the code throughout the project.

FAQ
Why should you choose me?
0+ years building .NET business software. I have delivered CRM systems for sales teams, logistics companies, real estate agencies, and service businesses. I write the code personally, manage deployment, and communicate directly — no middlemen. I also use AI and low-code tooling where it saves time,
What's included?
Every package includes working, deployed-ready source code, responsive web UI, and the specific modules listed in the package. Standard and Premium include role-based access, reporting, and email notifications. Premium adds REST API, AWS deployment, and advanced analytics. Full list is in the packag
What's not included?
Mobile native apps (iOS/Android), third-party API integrations beyond what is listed in the package, data migration from your existing system, hosting costs, and domain setup. These can be added as extras or quoted separately. If you are unsure whether something is included — message me before order
Do I need to provide technical specifications?
No. I will send you a short questionnaire about your business process, and I will translate that into a working CRM. A simple description of your workflow is enough to start.
Will the CRM work on mobile devices?
Yes. The UI is fully responsive and works on desktop, tablet, and mobile browsers without a separate app.
Can I import my existing data (Excel, CSV)?
Yes, data import from CSV/Excel can be added as a gig extra. I will map your columns to the new system fields and run a clean import.
How many users can work in the system simultaneously?
There is no built-in user limit. The system scales based on your server resources. For most small and mid-size teams, a standard VPS (EC2 t2.micro AWS for instance) handles hundreds of concurrent users.
Do you provide source code?
Yes. Full source code is included in every package. You are not locked into any platform or vendor.
What happens if I need changes after delivery?
Every package includes revisions as listed. After the order closes, I offer maintenance and enhancement as a separate service or through a new order.
How fast can you really build a CRM?
Because I use a proprietary rapid-development framework, I can deliver functional multi-module systems 3–5x faster than conventional development. The Basic package is 5 days by design — it is not a cut-down demo.
