Odoo Purchase Customization, WhatsApp RFQs & AI Bill ExtractionClient: Catch Foundation, Tree Plantation NGO (Ahmedabad, Gujarat, India)

Catch Foundation: Smart Purchase Management on Odoo with AI Bill Scan

Catch Foundation creates and restores green spaces: Miyawaki forests, green belts, urban and riverfront plantations. Steigern Tech engineered a smart purchase management system on Odoo to compare vendor prices item by item, send RFQs and purchase orders on WhatsApp, split orders across vendors, and read any bill format with AI.

The Engineering Challenge

Catch Foundation creates and restores green spaces: Miyawaki forests, green belts, urban and riverfront plantations. Every site needs saplings, tree guards, drip lines, compost and labour, often from several local vendors at once.

Steigern Engineering Solution

Every purchase for a plantation project follows nine connected steps on Odoo, ensuring each order decision is based on compared prices and recorded for audit: material requests from site, 1-click WhatsApp RFQ dispatch, AI quote reading, item-wise L1 price comparison, programme head approval, automated multi-vendor PO splitting, site receipt tracking, AI bill matching, and real-time dashboard analytics.

Odoo 19 Enterprise & Custom ModulesClient: Classic Collective (Bicester, UK)

Classic Collective: Car Workshop & Online Shop on Odoo 19 Enterprise

Classic Collective moved from Odoo Online to Odoo 19 Enterprise: a branded workshop website, an online parts shop with fitting options, event booking, and a module that imports supplier price lists in minutes.

The Engineering Challenge

Classic Collective already had products loaded on Odoo Online and wanted to start selling. But Odoo Online would not let them change the shop's menus, build pages for each product category or control how products were ordered inside them. Each supplier also shipped differently. Wagner additives went out from the workshop's own stock, Revotec and Team Dynamics parts were drop-shipped, and Vintage Tyres could only be delivered to the workshop for fitting. The team needed the website to say all of that, and to stop retyping supplier price lists by hand.

Steigern Engineering Solution

Steigern Tech migrated the entire database to Odoo 19 Enterprise on Odoo.sh with Git-based staging pipelines, implemented a bespoke racing green and navy brand theme with mega menus, engineered category-specific delivery and fitting modules, automated supplier price list imports with VAT and margin calculation, and launched online event registration and sustainability pages.

EducationClient: Ved mata gayatri School Fees Management (Global / Steigern Client)

Ved Mata Gayatri Education Trust: multi-school fee management ERP

One web ERP for eight schools of Ved Mata Gayatri Education Trust, Mansa: fee collection, admissions, staff salaries, expenses and Excel-ready reports across every school and standard.

The Engineering Challenge

The JS Patel Gayatri Educational Campus in Mansa runs eight schools on one campus, from pre-primary to higher secondary. At fee time, the office counter sees parents paying for children in different schools, by cash, cheque, UPI or under RTE. Each school kept its own registers. Answering a simple question from the trustees, "how much is still pending across the campus?", meant days of adding up ledgers.

SwissHardware: Shopify PC configurator with Odoo inventory sync

SwissHardware customers build a custom PC part by part on Shopify, with compatibility checks and live pricing, while stock is synced both ways with Odoo through an API integration.

The Engineering Challenge

A customer wants a gaming PC. They pick a shiny graphics card, then a CPU, then discover the motherboard doesn't fit, the power supply is too weak and the case they loved is out of stock. For SwissHardware, every one of those moments meant a lost sale or a support email. And behind the scenes, the store's stock in Shopify and the warehouse stock in Odoo told two different stories.

Terraza Montemar: Odoo restaurant POS with AI table delivery and ATH Móvil

A Puerto Rico seafood restaurant runs on a custom Odoo POS: kitchen display and printer, an AI app that assigns waiters to deliver ready dishes, QR tipping on bills and ATH Móvil payments.

The Engineering Challenge

Friday night at Terraza Montemar, "La Casa del Chillo Frito". The terrace is full, the sea breeze is up and three plates of fried snapper sit under the heat lamp. Nobody is sure whose table they belong to, and the waiter who took the order is across the restaurant. Great food was never the problem. Getting it from the kitchen to the right table while it was still crisp, and making it easy for happy guests to tip and pay, was.

Ocean Bakery: Omnichannel POS with Shopify Delivery, AI Bake Planning & Auto-Reordering

Ocean Bakery runs counter sales, online delivery orders, receipts with QR tips, AI bake forecasts and automatic ingredient reordering in one Odoo system connected to Shopify.

The Engineering Challenge

At 6 a.m. the ovens at Ocean Bakery are already hot, and the head baker is guessing. Make too few croissants and the lunch queue walks away. Make too many and they end up in the bin by evening. Meanwhile orders arrived from three directions: the counter, the website and phone calls for delivery. Each lived in a different place, and nobody could say with confidence how much flour was left until the bag was empty.

Healthcare Platform & Mobile AppsClient: Vishwa Kalyan Bharati (NGO) (National / India)

Jan Sehat Setu – Integrated Health Camp Management Platform

Jan Sehat Setu ("people's health bridge") is a single digital platform that connects everyone involved in a free health camp: the hospital that organises it, the doctors who treat patients, the volunteers who run the desk, and the patients who need care. Vishwa Kalyan Bharati wanted to run free health camps every month, across many hospitals and locations, without the paperwork and phone calls that usually come with them. Steigern Tech designed and built the full platform: a web panel for hospitals, a public website, and three mobile apps for patients, doctors and volunteers. All work on one shared backend, so a camp created by a hospital appears instantly for patients to book, for doctors to attend and for volunteers to join. Formally launched by Dr. Mansukh Mandaviya, Union Minister of Labour & Employment and Youth Affairs & Sports, Government of India.

The Engineering Challenge

Free health camps do enormous good, but they are hard to run well. Before Jan Sehat Setu, camps were announced through posters, WhatsApp forwards and word of mouth so many people who needed a screening never knew it was happening; patients turned up without appointments, waited for hours and were sometimes turned away when capacity ran out; doctors worked from handwritten slips that were hard to find later; volunteers were coordinated by phone without simple duty applications or recognition; hospitals managed each camp in its own spreadsheet without a single view of camps, patients, or doctors; and mothers booking for children and elderly parents had to register each person separately in chaos at the camp.

Steigern Engineering Solution

We built Jan Sehat Setu as one platform with five connected touchpoints. Each user gets exactly the tools they need, and everything stays in sync. Steigern Tech designed and built the full platform: a web panel for hospitals, a public website, and three mobile apps for patients, doctors and volunteers. All of them work on one shared backend, so a camp created by a hospital appears instantly for patients to book, for doctors to attend and for volunteers to join.

EducationClient: Discovery Land School (Global / Steigern Client)

DiscoveryLand Preschool: AI-powered preschool ERP with safe child pickup

How we built a preschool management system for DiscoveryLand with face-match child pickup, OTP for drivers, AI classroom report cards and WhatsApp updates for parents.

The Engineering Challenge

It's 12:30 on a weekday at DiscoveryLand's Satellite branch. Forty parents, drivers and nannies crowd the gate at once. A teacher holds a three-year-old's hand and has a few seconds to decide: is this the right person to take her home? That question, asked hundreds of times a day across two branches, is where this project began. DiscoveryLand needed more than a fee register. They needed a system that keeps children safe, keeps parents informed and gives the director a clear view of every branch without chasing anyone for updates.

Dublin University Football Club: Odoo website with Google Sheets fixtures and AI match tables

We took Dublin University Football Club (Trinity Rugby) from Figma to a live Odoo website with Google Sheets fixtures and league tables, AI-built match tables, a club shop and event booking.

The Engineering Challenge

Dublin University Football Club is the oldest club in the world in continuous existence, founded in 1854. Its website is run by volunteers: students, alumni and committee members who have a match on Saturday and exams on Monday. Every week someone had to update fixtures, results and the league table across seven teams by hand. When that person was busy, the website fell behind and supporters turned up for kick-offs that had moved.

Flutter App Development, Native iOS IoT Library, Machine Control, Contra AI & Admin PanelClient: Contra Farms ("Technology. Farming. Lifestyle."), indoor smart grow chambers (Global / Steigern Tech)

Contra Farms: IoT smart farming app in Flutter with a native iOS IoT library, remote machine control, Contra AI and an admin panel

Contra Farms builds indoor grow chambers: trays of seed pods that move from germination to grow, under LED shelves, with a water pump, nutrient dosing and a fan. Steigern Tech built a cross-platform Flutter app, a native iOS IoT library in Swift, remote machine controls, Contra AI suggestion engine, and an operations admin panel to manage every chamber from seed to harvest.

The Engineering Challenge

Contra Farms builds indoor grow chambers: trays of seed pods that move from germination to grow, under LED shelves, with a water pump, nutrient dosing and a fan. The hardware was full of sensors, but the readings stayed inside the box. A grower could not see from the sofa that pH had drifted, or that a shelf light was still on at midnight. Changing a setting meant standing next to the machine. And Contra Farms had no single view of the chambers across homes, cafés, schools and commercial farms.

Steigern Engineering Solution

System architecture: hardware sensors → native iOS IoT library → Flutter app → cloud API and database → admin panel and Contra AI, with commands flowing back to the machine's actuators (LED shelf lights, water pump and dosing, fan and misting).
