In an ever-changing digital world it is impossible to offer any guarantees about how long something will continue to work for without needing maintenance.
However, my ad-hoc PHP, MySQL, HTML and CSS work is usually guaranteed for 3 months - if problems with my work arise after completion, testing and sign-off by the client then I will resolve these free of charge provided no more than 3 months has passed since completion of the work.
If at any point during our working together you are unhappy with anything I have produced for you then you must tell me immediately.
I do not issue refunds.
