I know the question have been debated here, but I didn't quite find a lot of informations about developement (most was about CMS aka WordPress, Drupal)
So I did a mission of about 3 months with a big company (~65000 employees). The mission was about adding the missing features and debugging as Full-Stack (Laravel Backend, JQuery/HTML/CSS Front) of an internal reference database they use daily
Now they liked my work, they want a maintenance contract for this needs :
- maintenance of the server (adding a little bit of DevOps there) - potential debugging of the application - potential evolution of the application
And the contract should be an annual one
As I'm a bit starting of with big company as a freelancer, I don't know how I could price my maintenance contract. As a first try, I made one that charge an annual fee for the disponibility it imply accompagned with an ascending hour payments for each degree of maintenance they would (is the need impterative ? critical ? or simply a need of little debugging ?) but I don't know if it could fit as big company there tends to like all-in-one annual fees and basta.
So how could you see a good round up of this and maybe give a poential price ?
