POS, CRM and business software shaped to how your team works.
POS · CRM · Inventory
You've trained four new counter staff in the last eighteen months. Each took two weeks before they stopped asking the manager. Our screens get a new hire on the till the same afternoon.
- Custom POS
- Customer CRM
- Stock & inventory
Web & mobile apps
Your delivery team is still calling the shop to confirm pickup addresses. Your manager opens five tabs to write one daily report. We build the app your team would design if they could code.
- Customer apps
- Field-ops apps
- Operations dashboards
AI & automation
Your manager spends the first hour each morning copying yesterday's numbers from WhatsApp into a sheet. That hour is the one we automate first. The AI does the boring part. Your team keeps the judgement.
- Workflow automation
- AI search & drafting
- Voice-to-record tools
Cloud or offline
The wifi at your second branch drops twice a week. Your billing still has to work. We run on your shop floor when it must, sync to the cloud when it can. The person you call wrote the code.
- Cloud or self-host
- Works offline
- Localized for your team
Four steps. The same project manager from kickoff to the last commit.

Walkthrough
We sit beside the counter or open a call with the people who actually do the work, not the people who buy the software. You leave with a written scope and a fixed price. Not a "between X and Y" range you'll fight over later.
-
A clickable thing in 14 days
Two weeks in, you have a real URL on your phone. You click through it on the drive home. Your counter staff click through it the next morning and tell you, in fewer words than you'd like, what's wrong. We fix it before a single line of production code gets written.
-
A demo every other Friday
Every other Friday we walk you through what shipped, what slipped, and what we cut to hit the date. You'll never have to send the "any update?" message at the end of a quiet month.
-
Launch, then 90 days on call
We deploy, train your team in their language, and stay reachable for 90 days. Not a ticket portal. A WhatsApp thread with the people who wrote the code. After that, keep us on a retainer or take the keys. The code is yours from day one either way.
Products shaped by the businesses we build for.
Built for the shop that doesn't want to spend six months scoping its own software.
Pickup, wash, dry, deliver. Tracked end to end, in your team's language, online or off. Bend the workflow to your shop without filing a change request with us.

Clear answers about POS, CRM and inventory software.
What is POS and CRM software?
POS software records sales, payments and stock at the counter. CRM software keeps customer details, purchase history and follow-ups. When they work together, every sale updates the customer record and inventory automatically.
Can POS, CRM and inventory work as one system?
Yes. Seyon Labs builds one connected workflow for billing, customers and stock, so teams do not have to copy information between separate apps or spreadsheets.
Does Seyon Labs build custom POS software?
Yes. We adapt screens, permissions, reports and workflows to the way your business operates. The aim is practical software your counter staff can understand quickly, not a generic template with unnecessary features.
Can the software work offline or across branches?
Yes. A system can continue essential shop-floor work during weak connectivity and synchronize when the connection returns. Multi-branch deployments can provide shared customer, sales and inventory visibility.
Based out of Chennai. Built for shops everywhere.

Tell us the one thing in your shop that should already be software.
A paragraph is enough. Within a working day you get questions back, a rough scope, and an honest read on whether we're the right team. If we're not, we'll say so before you've spent an hour on a call.
