Questions
How long does a project take?
A standard site takes 3–7 days. Web apps and custom systems run 2–6 weeks depending on scope.
Do you build for both iOS and Android?
Yes. We ship one cross-platform codebase to both stores, or go fully native when the project needs it.
Can you integrate with software we already use?
Yes. Payments, accounting, CRMs, delivery and stock systems via API integrations or webhooks.
Do you offer payment plans?
Yes. Typically 50% deposit to start and 50% on delivery, with monthly retainers for ongoing work.
