RED SAG is a software development company in India, working from Arulpuram in Tiruppur. We build billing and POS systems, GST-ready accounting tools, e-commerce stores and custom web and mobile apps for businesses that want software shaped around how they actually work, not a generic package they have to bend around.
Many of the businesses around us are knitwear and garment exporters, textile and dyeing units, retailers, clinics and small manufacturers across Tiruppur, Coimbatore and Erode. Their problems are specific: tracking orders across job-work units, raising GST invoices quickly, collecting payments by UPI, and answering customers who prefer WhatsApp over email.
We also work with founders and startups across India who need an MVP, a SaaS product or a dependable developer on a monthly basis. You can talk to us in Tamil or English, and for clients in Tiruppur or Coimbatore we can meet in person to understand the workflow first.
For clients in Tiruppur, Coimbatore and nearby towns, we can sit with your accounts, stores or production staff before writing a line of code. Seeing how orders, stock and invoices really move saves weeks of guesswork later.
Owners, supervisors and billing staff do not all think in English. We explain screens, training and changes in Tamil where that helps, and keep written specifications in English so everyone has one clear record.
We integrate Razorpay, UPI and other Indian payment gateways, and design around WhatsApp for order updates, payment links and invoice sharing, because that is where most of your customers already respond.
Invoices, credit notes, HSN codes, tax splits between CGST, SGST and IGST, and exports for your auditor are planned into the data model early, not patched in at year end.
You get a written scope and a fixed quote in rupees for defined work, with a clear line on what counts as a change. Small businesses can start with the core module and add more once it is paying for itself.
GST billing and POS software for retail, restaurants, supermarkets and pharmacies, customised from our OverseePOS product.
Production, job-work and costing software for garment and knitwear units, built by a team based in Tiruppur.
Shopify, WooCommerce and headless Next.js stores with payments, shipping integrations and B2B ordering for D2C and export brands.
GST-ready invoicing, bank reconciliation, multi-currency billing and ERP-lite tools that sync with Tally, Zoho, QuickBooks or Xero.
Multi-location stock, batches, barcodes and mobile audits for distributors, wholesalers and manufacturers.
Origination, EMI schedules, field collections and overdue tracking for NBFCs, MFIs, societies and gold-loan lenders.
Appointments, EMR, prescriptions, billing, pharmacy stock, lab reports, teleconsultation and WhatsApp reminders for clinics, labs and small hospitals.
Admissions, online fee collection, attendance, timetable, exams, report cards, parent app and transport for schools, colleges and coaching centres.
CRMs, field-sales apps, inventory tools and dashboards built around your process, with WhatsApp, email and Tally/Zoho integrations.
Best for a billing system, website, online store or a clearly defined internal tool. We agree the screens, reports and integrations in writing, quote a fixed INR price, and usually split payment across milestones such as design sign-off, first working version and go-live.
Suited to startups and growing companies with an ongoing product roadmap. You get a developer (or a developer plus designer or tester) working on your priorities each month, with weekly demos and access to the code repository from day one.
For businesses that already have software or a website running. A fixed monthly fee covers bug fixes, small changes, backups, server and SSL renewals, and updates when GST rules or payment gateway requirements change.
Our working hours are Monday to Friday, 9AM to 6PM IST. Since we are in the same time zone as you, calls, screen-sharing sessions and quick clarifications all happen during your normal business day.
For local clients we typically meet in person for the requirement discussion and again for training at go-live. In between, we use short phone or Google Meet calls and a shared WhatsApp group so owners and staff can raise issues without waiting for a meeting.
Clients in Chennai, Bengaluru, Mumbai, Delhi or elsewhere work with us remotely: a kickoff call, a written scope, weekly video demos and a staging link you can test on. Most projects never need a physical visit.
We build invoices with correct GSTIN, HSN/SAC codes and tax splits, and can prepare data for e-invoicing (IRN) and e-way bill workflows where your turnover requires them. Your chartered accountant should confirm the tax configuration before go-live.
If your software stores customer or patient details, we design with the DPDP Act, 2023 in mind: collecting only what you need, recording consent where appropriate, restricting staff access by role and keeping a way to correct or delete records.
Card and UPI payments are handled by regulated gateways such as Razorpay, so card details never touch your server. This keeps you aligned with RBI tokenisation rules and avoids storing sensitive payment data yourself.
Hosting can be on Indian cloud regions if you prefer data to stay in the country. On full payment, the source code and credentials are handed over to you, so you are never locked in to us.

Indicative monthly cost for a full-time developer working on your product, depending on experience and tech stack. Includes project management and code reviews; minimum engagement is usually three months.
Indicative budgets based on typical projects. Your fixed-price quote depends on scope, integrations and timeline.
We are a software development company based in Arulpuram, Tiruppur, Tamil Nadu. For businesses in Tiruppur, Coimbatore and nearby areas we are happy to visit your office, shop or factory for the first requirement discussion and for training at go-live. Clients elsewhere in India work with us over video calls and shared staging links.
Yes. Exporters usually need more than a billing screen: buyer-wise orders, style and size breakups, job-work tracking across knitting, dyeing and stitching units, packing lists, and export invoices alongside domestic GST invoices. We map your current process first and then build only the parts that save you time.
It depends heavily on scope. As a typical guide, a starter business website costs ₹15,000 to ₹25,000, and larger sites with more pages or features cost more, while a billing system or startup MVP usually falls between ₹90,000 and ₹4,75,000. We give a fixed written quote after understanding your requirements, so there are no surprise charges later.
Ready-made packages work well for standard retail billing, and we will tell you if one suits you. Custom software makes sense when your process has steps those packages do not handle, such as job-work tracking, multiple branches with different pricing, or linking billing to your online store and WhatsApp orders.
Yes. We regularly add Razorpay payment links and checkout, UPI QR codes on invoices, and WhatsApp messages for order confirmations, payment reminders and invoice PDFs using the official WhatsApp Business Platform. Gateway and messaging charges are paid directly by you to those providers.
We build GST handling into the design: CGST and SGST for intra-state sales, IGST for inter-state and export sales, HSN codes, credit notes and reports your auditor can use for filing. Tax rules change, so we recommend your chartered accountant reviews the configuration, and our maintenance plans cover later rule updates.
Yes. As a remote-friendly software development company in India, we work with founders across the country on MVPs, SaaS products and mobile apps. We agree a written scope, share progress in weekly demos and give you access to the code repository from the start, so location is rarely an issue.
You do. Once the project is paid in full, the source code, database and all account credentials are handed over to you. We can continue maintaining it on a monthly plan, but you are free to move it to another developer or in-house team whenever you like.
