Very knowledgeable, very responsive support staff who will provide very customized and informed guidance, typically within 2 hours.

SurveyCTO has a quick learning curve. It makes it possible for anyone to pick it up quickly and program a survey - and having that power, instead of relying on a programmer, makes work much more efficient and high quality. You can check the logic of the questionnaire yourself, for example, or make a last minute change quickly without having to rely on a programmer to have the time. The company also has great customer support - pretty rare in programming - you can write a question to the helpline, however basic it might be, and get a quick response pointing you to the answer or the resources you need.

SurveyCTO makes it easy to program complex surveys and has many features to ensure that surveyors collect quality data. The help section of their website is incredibly thorough, and if you write-in to get support the response time is fast and the instructions are always very clear. SurveyCTO allows you to program surveys and collect data offline and sync later, and it's easy to make changes to the survey, even once you have begun collecting data. The interface is friendly and very easy for surveyors to use.
