Off-the-shelf software gets most businesses started. Then the workarounds pile up: spreadsheets on the side, copy-pasting between tools, a process only one person understands. A custom web app replaces all of that with one system built around your workflow.

DEVR Tech builds web applications for startups and established businesses across Singapore and Malaysia — booking platforms, CRMs, management systems, marketplaces, and point-of-sale tools. Recent work includes a co-working booking platform for Meletis, a placement CRM for Nanyang Employment Services, and a gold POS system for Jin Sing Li.

Everything we build is responsive, so it works on phones, tablets, and desktops, and it's designed to grow with you — from the first users to the busiest day of the year.

Custom build or off-the-shelf?

If an existing tool covers most of your process and the gaps are tolerable, start there — it's cheaper and faster. Build custom when the workarounds are costing you time or revenue, when your process is what sets you apart, or when the software itself is your product.

A good first step is a focused first release that replaces the most painful part of the workflow. You see results sooner, and the next phase is shaped by real usage instead of guesses.

Web App Development FAQs.

How much does a custom web app cost?

Should I build custom software or use an off-the-shelf tool?

If an existing tool fits most of your process, start there. Build custom when workarounds are costing you time or revenue, or when the software is your product. We'll give you honest advice either way.

Will the web app work on mobile?

Yes. Everything we build is responsive, so it works on phones, tablets, and desktops. If you also need a native app, see our mobile app development service.
