Custom application development FAQs

How much does it cost to build a custom application?

It depends on scope: the number of screens, how much logic sits behind them, and what it has to integrate with. A focused internal tool or MVP is a very different figure from a multi-role SaaS platform. We scope the build first and give you a fixed, itemised quote before any code is written — no open-ended hourly billing.

How long does development take?

A working MVP typically takes six to twelve weeks; a larger platform runs longer and is phased so you get something usable early. Design and a clickable prototype come first, so the timeline is agreed against something you have already seen rather than a specification you have only read.

Web, mobile, desktop — which is right for my idea?

It follows from who uses it and where. Staff at desks and admin work suit a web app; field teams, scanning and offline use point to mobile; some products need both, sharing one back end. We recommend the combination that fits your workflow and budget rather than defaulting to building everything.

Can the application connect to our ERP or existing systems?

Yes — that is most of what we do. Applications talk to Odoo and other ERPs, accounting systems, payment gateways and third-party services through clean APIs, so data has one source of truth and your team is not re-keying it between systems.

Do you deploy and publish it (servers, Play Store, App Store)?

Yes. We handle server setup, domains, SSL and deployment pipelines, and we publish mobile apps to the Play Store and App Store under your own developer accounts — so the listings stay yours.

Do we own the source code, and is there support after launch?

You own the source code, the accounts and the IP outright — it is handed over on completion. Support after launch is optional: we offer an AMC covering updates, fixes and enhancements, but you are free to take the code to any other team.
