CUSTOM SOFTWARE DEVELOPMENT // FREQUENTLY ASKED QUESTIONS

Frequently Asked Questions

Everything you need to know about timelines, source code ownership, tech stack choices, and post-launch maintenance for Custom Software Development.

Generic software forces you to change your workflow to fit its limitations and charges expensive recurring seat licenses. Custom software is built exactly to match your distinct operational advantages with zero perpetual license fees.

Absolutely. Our technical data engineering team cleans, maps, and bulk-imports your historical transactions, client ledgers, and opening stock with 100% reconciliation.

Yes, we can deploy on your local enterprise server with LAN access across your office, backed by automated scheduled off-site encrypted backups.

Because you own the code and work directly with our engineering team, we can adapt calculation formulas, tax rates (VAT/SSCL), or add new modules whenever your business scales.

We provide hands-on training sessions for your management and operational staff, along with comprehensive user manuals and video walkthroughs.

None. You own the software with perpetual commercial rights. You only pay for your choice of infrastructure hosting and optional ongoing support SLAs.
