Application Development

It is building software people log in to and use. A customer places an order. A partner checks a commission. A field team records a visit. The app holds the rules, the data and the permissions behind each of those actions.

The screens are rarely the hard part. The hard part is deciding what the app should know, who may see what, and how it shares data with the rest of the business. That is where we spend the early conversations.

Businesses that want customers or partners to do things themselves, instead of calling to ask. Companies launching a first mobile app. Teams whose systems do not talk to each other, so staff retype figures from one into another. And sellers who need payment gateways set up properly, once.

If you already have a quote or a half-built app and want a plain opinion first, the Tech Second Opinion gives you one in a short written report.

• Mobile apps: iOS, Android and cross-platform, including apps that keep working without internet. See mobile app development.
• Web applications and portals for customers, partners and staff.
• Payment gateway integrations with Razorpay, Stripe and bank gateways. See payment gateway integration.
• APIs and third-party integrations. An API is an agreed way for two programs to exchange data, and we build the connections between your software and other tools.
• WhatsApp Business API: order updates, notifications and conversations sent from your own systems. See WhatsApp Business API integration.
• ERP, CRM and accounting integrations. ERP is the software that runs a company's operations, and CRM holds customer records. We connect them so the numbers agree.
• App maintenance and support: updates, fixes and monitoring.

Some apps are really products you sell. If yours is one, see Product Development. If you want an assistant or an automation inside the app, see AI Systems & Automation. Either way, it stays with the same team.

We use The Path. In Listen, which starts on day one, we learn who uses the app and what they need to get done. In Shape, before any build, we agree how it will be built, what the screens look like and a written scope. Build runs in sprints you can see, with a working demo each time. Launch happens when you are ready, after testing on real devices, with store submissions where needed and a full handover. Evolve is the support that follows.

You set the pace, and we agree the schedule with you at the start. For mobile apps, store reviews sit with Apple and Google, and we plan around them.

The TechSum Standard applies to every app we build:

• Secure by default: logins, roles and permissions decided before the first screen, so each person sees only what they should.
• Built to scale: more users, more orders or a new integration means more capacity, not a rewrite.
• Tested before it ships: main tasks tested on the phones your customers actually own, and every payment path tested end to end.
• Looked after after launch: updates for new phone versions, fixes and monitoring, logged where you can see them.
• Small changes handled, not invoiced: a wording change on a screen or a tweak to a notification gets done. It does not become a change request with a price on it.
• Honest advice, even when it means less work for us: if a web app does the job without a download, or a no-code tool will do for now, you hear it from us first.

People finish the main task without help. It works on the phones your customers actually own, not only the newest ones. Payments arrive and match your accounts. Data moves between the app and your other tools without anyone copying and pasting.

It is also easy to hand over. You own the documentation, the test and live setups and every login, so another developer could pick it up.

If you need a quick prototype with no real users, a no-code tool may be faster and cheaper, and we will say so. Games and hardware products are outside our work. You will hear both on the first call.
