Frequently asked questions

Straightforward answers to how we work, what to expect, and how we keep your projects moving securely and smoothly.

How long do projects usually take?
Smaller pilots or prototypes are typically delivered in 2 to 6 weeks. Larger custom builds range from 8 to 16+ weeks depending on scope and complexity. We always provide clear timelines upfront.
What does your pricing look like?
We tailor pricing to your project. Simple, well-defined scopes are usually fixed-price, while larger or evolving projects are milestone-based with transparent estimates without hidden costs.
How do you keep our software secure?
Security is built into everything we deliver. All data is encrypted in transit and at rest, access is tightly controlled, and regular updates keep your systems protected. We also follow GDPR standards as a UK-based partner.
Who owns the software once it's built?
You do. Once full payment is made, all intellectual property transfers to you. With your permission, we may showcase the project in our portfolio.
Will your solutions work with our existing systems?
Yes. We specialise in integrations and phased rollouts, meaning we connect with your current systems and avoid unnecessary disruption whilst modernising your workflows.
What kind of support do you provide after launch?
We offer flexible support plans to keep your systems secure, updated, and running smoothly so you can focus on growing your business, not fixing tech issues.
