How Projects Work
Clear expectations from the start, so you know what to expect before any work begins.
Written quotation and defined scope
Larger projects receive a written quotation and a clearly defined scope before work begins, so you know exactly what is included.
Payment schedule
Payment is normally split 50% before work begins and 50% on completion. Smaller projects may be handled differently.
Work outside the agreed scope
Any material work outside the agreed scope is quoted separately, so there are no surprises.
Timelines
Timelines depend on the scope of work, access to systems, client response times and any third-party approvals.
App Store and Play Store
App Store and Play Store approval cannot be guaranteed — it depends on Apple and Google review processes.
Third-party costs
Third-party subscriptions, platform charges and external service fees are not automatically included unless stated in your quotation.
