Frequently Asked Questions.
How much does a software or website project cost?
Every project is different. A business website costs less than a real-time trading interface, an e-commerce store, or a SaaS platform. We offer fixed pricing with no hidden fees — book a free consultation and we'll give you an honest quote tailored to your needs.
How long does a project take to build?
A business website typically takes 2–4 weeks. More complex work like e-commerce stores, SaaS platforms, or trading interfaces takes 2–4 months. We set realistic timelines from day one and provide weekly progress updates.
Do you offer monthly payment plans?
Yes. We offer flexible payment options including milestone-based payments and monthly plans for larger projects. We'll discuss what works best for your budget during the free consultation.
Can I see examples of your work?
Absolutely. We have 26 live demo projects you can browse at appstackx.co.uk/work, covering 11 different industries. We can also show you something specific to your sector.
