# AI systems and software for retail and manufacturing > AI automation, custom ERP and business software for small and mid-sized retail and manufacturing businesses in India, built in Chennai on the systems you already run. Source: https://deda.systems/ Last updated: 2026-11-13 **We walk your floor first. Then we build.** Deda Systems is an engineering studio that builds AI automation, custom ERP and business software for small and mid-sized retail and manufacturing businesses, on top of the POS, ERP and spreadsheets you already use. You know your stock, your production and your money every morning, without waiting for month-end. - **Works with:** The POS, ERP and Excel you already run - **Runs:** In your office, or in the cloud - **Pricing:** Fixed scope, fixed price - **Languages:** English and Tamil *Screen: Daily summary on a phone showing yesterday's sales, low stock, shop floor OEE and month-end entries, over a multi-branch stock dashboard. Your business, every morning: one short summary of yesterday, on your phone, with the full detail a tap away. Illustrative screen with sample data.* ## Problems we fix for owners These are the six things we hear most often from people who run shops and factories. If one of them is yours, that is where the first project starts. | What owners tell us | What we build | | --- | --- | | “Our stock on paper never matches the shelf.” | One live stock position across every branch, read from the billing entries your staff already make. [See the retail stock case study](https://deda.systems/case-studies/multi-branch-retail-stock-visibility) | | “Month-end takes my accounts team a full week.” | Bank statements, books and GST matched by the system. Your accountant reviews the few lines that do not match. [See the month-end case study](https://deda.systems/case-studies/month-end-gst-bank-reconciliation) | | “I hear about yesterday's production this morning.” | Job cards filled in at the machine, so output, rejects and stoppages are visible during the shift. [See the job card case study](https://deda.systems/case-studies/paper-job-cards-to-live-oee) | | “Defects are being found by my customer.” | A camera on the line checks every part, trained on your own products and your own defect types. [See the inspection case study](https://deda.systems/case-studies/vision-quality-inspection-moulding-line) | | “Everything runs on WhatsApp groups and phone calls.” | Approvals, forms and follow-ups moved into simple software built around the way your team already works. [Custom ERP and business software](https://deda.systems/custom-erp-software) | | “Our ERP has all the data, but I cannot get answers from it.” | Dashboards, alerts and a daily summary on top of the POS or ERP you already run, without replacing it. [An AI layer on your existing systems](https://deda.systems/custom-erp-software) | ## Two industries, three kinds of work We work only with retail businesses and factories. Everything we have built was built for a shop or a plant, so we already know the problems before you explain them. - **R · [Retail chains, run on numbers](https://deda.systems/ai-for-retail):** Live stock across every branch, buying planned from demand data, and a month-end that closes without spreadsheets. - **M · [Factory floor intelligence](https://deda.systems/ai-for-manufacturing):** Paper job cards to live OEE, vision inspection on the line, and downtime you see coming from your own machine data. - **S · [Software around your process](https://deda.systems/custom-erp-software):** Custom ERP modules, digitised forms and workflow automation, or an AI layer on the POS and ERP you already run. ## What the engineering covers Six kinds of work, from getting your data into one place to AI that runs every day. Most projects combine two or three of them. - **01 · Process automation:** Data entry, document processing and syncing between systems, mapped, digitised and running around the clock without a person in the loop. - **02 · ML model development:** Demand forecasting, anomaly detection and classification models, trained on your operational data and deployed as APIs your systems can call. - **03 · AI systems and agents:** LLM-based document intelligence, operational Q&A and automated reporting from your own business data. Fully private, and on-premise where required. - **04 · Data pipelines and dashboards:** ERP, POS and spreadsheets consolidated into one source of truth, with live dashboards built for owners, managers and floor teams. - **05 · Computer vision:** Quality inspection, inventory counting and production monitoring, trained on your products and defect classes, on edge hardware or in the cloud. - **06 · ERP integration:** An intelligence layer on the ERP, POS or legacy system you already run, so alerts, reports and automations work from data that is already there. ### Tools we run in production | Layer | What we use | | --- | --- | | Application | Python, FastAPI, React, Streamlit | | Data | PostgreSQL, SQL Server | | Machine learning | PyTorch, Scikit-learn, Prophet, OpenCV / YOLO | | Language models | LangChain, LLaMA / Qwen (local) | | Deployment | Docker, Railway / cloud | | Integrations | ERP and POS systems (including SAP Business One and Tally), bank and GST APIs, RFID systems | ## The work in practice Four worked examples, two from retail and two from manufacturing: what the business looks like today, what we build, and what changes on a normal working day. - **[One live stock view for a six-branch garment retailer](https://deda.systems/case-studies/multi-branch-retail-stock-visibility):** Six branches, six separate billing files and a weekly Excel sheet. How one live stock position, reorder alerts and branch transfers replace the Monday phone calls. - **[Month-end close without the spreadsheet week](https://deda.systems/case-studies/month-end-gst-bank-reconciliation):** Bank statements, accounting ledgers and GSTR-2B matched by the system. The accounts team reviews a short list of exceptions instead of ticking thousands of lines. - **[From paper job cards to live OEE in a CNC machine shop](https://deda.systems/case-studies/paper-job-cards-to-live-oee):** A machine shop that learns about yesterday's production the next morning. Tablet job cards at each machine give the owner live output, rejects and a reason for every stop. - **[Checking every part on a moulding line with vision inspection](https://deda.systems/case-studies/vision-quality-inspection-moulding-line):** Checking a sample from each batch lets defects reach the customer. A camera over the line, trained on the plant's own parts, checks every piece and tells the supervisor when rejects start rising. ## Six phases, in the same order, on every project We spend days in your shop or plant before we quote, so the proposal is about your business. [See the full walk-through](https://deda.systems/story). 1. **We show up.** On-site observation. 2. **Map the invisible.** Process archaeology. 3. **Find what is costing you.** Bottleneck diagnosis. 4. **Wire it together.** Systems architecture. 5. **Ship in sprints.** Weekly builds. 6. **The operation after.** Handover. Day 0: free call → Days 2–4: on your floor → Week 1: first demo → Weeks 6–12: in production ## A studio, not a services desk - **01 · Two segments only:** Retail and manufacturing, and no generalist IT services. Every tool, model and framework we own applies directly to your domain, so you are not paying for our learning curve. - **02 · You talk to engineers:** There are no account managers in between. The engineers who join your first call are the ones who scope the work, build it and support it. - **03 · Data stays in your building:** We support fully on-premise deployment, including local language models. Financial records, production data and customer information never have to leave your premises. - **04 · Systems that stay in production:** Everything we build is deployed, monitored and maintained. We stay involved until it runs in production and your team is confident operating it without us. ## Frequently asked questions ### What does Deda Systems do?
