In general, the response times are less than 48 hours. For blocking tickets or high priority tickets, the time is mostly less than 2 hours.
The processing time is generally about 3 to 5 days after acceptance of the ticket. These delays may be more important depending on the ticket size and may vary depending on the schedules. In the case of an emergency, if you have a blocking bug (i.e. preventing the order process), the processing of the ticket is in high priority and will be done in the day (working days).
The estimates are made the most accurate way to reduce costs and are based on our experience of the field (about 600 hours of maintenance every month). In some cases, an analysis may be necessary to establish an accurate estimate. The cost of this analysis will be communicated to you in response to your request.
There are, in some cases, unforeseen events on a ticket (additional communications, unforeseen technical matters, bad understanding, etc..), that can lead us to reevaluate the original estimation. In the case of unforeseen technical, involving additional costs, you have always the choice between continuing on the new budget, or to return to the initial state and we will refund you the time credits.
As seen in the previous question, a cancellation of a ticket is always possible : repayment of credits, and get back to the initial state before intervention. We can also can propose an analysis and fix for the problem described according to the following conditions : If it turns out that the problem was caused by a developmental error or a bad configuration from our part, it will be treated free of charge. In the opposite case the time spent would be counted.
Our developments are validated only once you confirm the ticket as resolved. Note we do not guarantee side effects or problems on codes developed by third parties (ex: plug-in another editor, the native codes of Prestashop). We advise the best, according to our knowledge, but in some special cases matters cannot be anticipated (for example, interactions between different modules, atypical data structure etc...). In order to guarantee you the best quality of service, we also recommend that you set up a pre-production environment allowing you to validate developments before their deployment. In case of a bug, whatever it is, there is always a solution !
