Ordering app

Example

Move trade orders off email and spreadsheets

  1. Built the order screens your sales team approved
  2. Loaded 1,240 customers and 3,800 products from the ERP
  3. Placed 60 test orders, and every one reached the ERP

  4. Give your first 20 customers their logins on Monday?

An example with made-up figures. The buttons send nothing.

How web app development works.

  1. You show us the spreadsheet

    The file, inbox or paper form the work runs through today. We watch how your team uses it, workarounds included.

  2. We turn it into an app

    Clear screens in the browser, each record kept once, and each person seeing only the part that is theirs to do.

  3. Everyone works from one place

    Staff and customers log in from a laptop, tablet or phone. Nothing to install, and no version sent round by email.

Web apps we build.

Start with the file that holds up the most work. Each tab puts the way it runs today next to the web app we would build in its place.

  • Today

    Bookings are taken by phone and a shared calendar

    With a web app

    Customers book themselves, and the calendar stays right

    Customers pick a free slot, a service and a location in the browser and get a confirmation right away. Your team sees the same calendar, with no double bookings and no calls to return.

    Any hourfor customers to book

  • Today

    Orders arrive by email and are retyped

    With a web app

    Trade customers order straight into your system

    Regular customers log in, see their own prices and reorder in a few clicks. Each order lands in your ERP as it is placed, so nobody retypes it and nobody misreads a scanned form.

    Typed onceby the customer, not again by your team

  • Today

    Managers wait for a weekly spreadsheet

    With a web app

    The figures you ask for, on one screen

    Sales, jobs and stock from the systems you keep are shown on one screen, updated as the work happens. Managers open a link instead of waiting for someone to build the report.

    The real process lives in one fragile spreadsheet

    With a web app

    An app that does what the spreadsheet tried to

    Job tracking, approvals or stock requests move into an app with proper logins, required fields and a history of every change. Nobody overwrites anyone else, and the process no longer depends on the one person who built the file.

    One versionthat everyone works from

How you stay in control.

Moving your customers and daily work into a new app needs care, so every web app we build ships with these four rules.

  • You approve every release

    Each new version lands on a test copy of the app first. Your team clicks through it, and real users see it only after the person you name says yes.

    • You name who signs off
    • A working demo every week
    • Any release can be rolled back

  • Your app, your data, your accounts

    The app runs in your own cloud account and the code lives in your own repository. Customer records stay on servers you control, under your name.

    • Hosted in your cloud account
    • NDA, MSA and DPA before any customer data
    • Logins by role, so staff see their own part

  • Connected to the systems you keep

    The app reads from and writes to your ERP, CRM and accounting software, so nobody copies data across by hand. We build it with React, Next.js, Angular, Node.js and PHP, tools your IT team already knows.

    • Connects to your ERP, CRM and accounting software
    • Built with tools your IT team knows
    • Built to pass your security review

  • You see how it is used

    An admin screen shows who logs in, what gets done in the app and how fast its pages load. You decide what to build next from how people really use it.

    • Usage shown from the first day
    • Page speed checked on every release
    • Spend shown against the fixed price

Web app project timeline.

You can stop after any stage. In week three your own staff are clicking through the main screens, with your field names already on them.

  1. Week 1

    Audit

    We sit with the people who use the spreadsheet or inbox today, map each step and agree on which screens the first release needs.

    You end withA plan and a fixed price.

  2. Weeks 2 to 3

    Prototype

    Clickable screens with your own fields and labels. Staff and a few customers try them and point out what is missing.

    You end withScreens your users have approved.

  3. Weeks 4 to 8

    Build

    We build the app with a working demo every week, connect it to your systems and test it on phones, tablets and laptops.

    You end withA web app your IT team has signed off.

  4. Weeks 9 to 10

    Go live

    One team or a small group of customers logs in first. The old spreadsheet stays read-only until everyone has moved across.

    You end withAn app in daily use, and a list for the next release.

After launch we keep a dedicated team on the app, or hand it to your team with full documentation. You decide.

Start with a free first step.

Send us the spreadsheet your team fights over, or the inbox or paper form they live in. On day five you get the screens it should become, and a price.

    Being associated with iTechnoSol was a pleasant and satisfying experience. They are good at many things, but I can't forget these two things in particular - their speed of response and clear understanding of my ideas. The team is really talented and was always available to answer my questions and to provide feedback. They beautifully nurtured the project and delivered it accordingly. I am delighted with them. Such a catch!

    For iTechnoSol, there is only one word in my mind - Fantastic! I am not just impressed by their service quality, but also for their working strategies. I am never going to regret my decision to hire them for the development of my mobile application. They have really made me happy by delivering an exceptional solution and extraordinary web design. They are talented and attentive. Most importantly, THEY CARE about client needs. Highly recommended.

  • I am looking forward to giving my future projects to iTechnoSol again.

    Read the full quote from Web app redesign client

    I already had a web application, but it was not up to the mark. So, I gave that project to iTechnoSol and told them that they are free to do anything, just give me a trendy but user-friendly app. I thought that redesigning existing projects is quite tough as the teams have to mold their thought processes according to my comfort zone, but I must say that they left no loophole in their work and offered a design that is a treat to the eyes! I am looking forward to giving my future projects to iTechnoSol again.

    We needed user-friendly software for customers so that they can get easy access to our services even without any admin support. When we discussed the project with iTechnoSol, they understood our ideas of business in detail and promised to deliver what we wanted. And yes, they have kept their promise. Keep up the good work, iTechnoSol. We hope we meet again soon for other projects shortly.

  • iTechnoSol stood behind us like a rock!

    Read the full quote from Outsourcing client, four-person team

    We are a team of four people who dream big and take a lot of projects altogether. So, we often need to outsource some of our software projects. We came to know about iTechnoSol from one of our clients, and we approached them. Within a day or two, they arranged an enthusiastic and dedicated development team through their software consultancy services! That project was big and very important for us, and we must say iTechnoSol stood behind us like a rock! Thank you buddies for all your love and support. We highly recommend this software company.

Web app questions.

What buyers want to know about price, phones and tablets, the technology and who owns the app.

When should we choose a web application instead of a mobile app?

A web application is often a good fit when people need access across devices without installing software. A mobile app may suit frequent field use, deeper device features or specific offline requirements. We review the user journey and device constraints before recommending an approach.

How much does web application development cost?

The price moves with the number of screens, the kinds of users who log in and the systems the app has to talk to. The free 5-day audit turns that into a fixed price, and you decide after seeing it.

What is the difference between a website and a web application?

A website tells people about your business. A web application is where work gets done: people log in to book, order, approve or check a status. Both open in a browser, so there is nothing to install.

Will it work on phones and tablets?

Yes. We build and test every screen for phones, tablets and laptops, so it works in any modern browser. If your staff need to work offline or use the camera all day, we will say in the audit whether a mobile app suits them better.

Which technologies do you build web apps with?

Tools your IT team already knows: React, Next.js, Angular and TypeScript for the screens, Node.js and PHP behind them, and AWS for hosting. If you already run something else, we start from that.

Who owns the web app once it is built?

All of it is yours from day one. The code sits in your own code repository, the app runs in your cloud account and customer records stay on servers you control, with full documentation. Part ways with us and you keep all of it, at no extra cost.

How do we work with a team based in India?

You speak to a founder first. We overlap 3 to 4 hours with the US and UK business day and answer within 4 business hours, in the tools you already use.
