I will build a custom crm or business web app to replace your spreadsheets
Oleh Fedkiv
About this gig
Still running your business in Excel, WhatsApp and memory? I'll turn your spreadsheet into your own simple CRM: one app where every client, booking and payment lives.
I'm a full-stack developer (Next.js, React, Node.js). I built and run a production booking platform with a CRM, PDF booking parsing and CSV export, so I know how real small businesses work.
What you get:
- Client base: contacts, history, notes, search and filters
- Online booking: clients pick a free slot themselves, from any phone
- Payments: subscriptions or one-off, with "paid / unpaid" always visible
- Dashboard: today's schedule, revenue, who owes what
- Email reminders and alerts to WhatsApp or Telegram
- Your Excel or Google Sheets data imported, nothing lost
- Fast, secure, mobile-friendly, and you own 100% of the code
Perfect for coaches, studios, salons, clinics, rentals, agencies and service businesses.
How it works:
- Send me your spreadsheet and tell me how you work today
- I build it, sharing progress as features are ready
- You get a deployed app, your data moved in, and a short walkthrough
Not sure which package fits? Message me first and I'll recommend one.

FAQ
Can you import my existing Excel or Google Sheets?
Yes. Send me the file and I'll clean it up and move all your clients into the new CRM.
Why not just use HubSpot or another ready-made CRM?
Ready-made CRMs charge monthly per user and force their workflow on you. A custom CRM fits exactly how you work, with no subscription to me.
Do I own the code and the data?
Yes, 100%. The code, hosting and database all live in your own accounts.
Can you really deliver in 1-2 days?
Yes. I work from a ready, tested CRM base and adapt it to your business, so you get a working app fast. Bigger custom features go into the Premium package.
Will it work on my phone, and what does hosting cost?
Yes, you and your clients can use it from any phone. Hosting on Vercel and Supabase usually costs $0-25 per month for a small business.
