1125245 2010-08-07 06:46:00 Hello,

I want to develop open source software. Could some please advise how I calculate what price to charge for support and amendments?

Thanks in advance.

1125247 2010-08-07 08:47:00 True, so what are you wanting to know?? Some open source programs MAY have an option to give a donation Speedy Gonzales (78)

You can certainly sell open source software.
'Open source' just means that you must supply the source code along with any binaries built from such.

@ OP
Charge whatever you think your time is worth.

1125249 2010-08-07 09:12:00 I know that the likes of A2Billing (A VoIP Billing application) charge 100 Euros for support. It's expensive, but worthwhile.

Depending on the applications that you're modifying, the type of modifications, you could realistically start anywhere from $30 an hour to $150 an hour?

1125250 2010-08-07 09:16:00 I would agree with fred, carge what you think the programming was worth. also if similar programs/projects exist charge a similar price in order to get your competition, make sure people know your project is better so they buy/donate The Error Guy (14052)

'Free' as in speech, not necessarily as in beer :)

Ok, sorry, I stand corrected.

1125253 2010-08-07 11:02:00 I agree with fred on this. The binaries and source code are supplied to the world as a whole and the source may be modified by anyone at any time.

Other than that you could try shareware or trial.

Then you have to figure out how to send an invoice to a user of the software you may create.

If users want more features then do same if feasible but send the requester an invoice or don't do it.

I want to develop open source software . Could some please advise how I calculate what price to charge for support and amendments?

Thanks in advance .

It depends on a number of things . Are you
a) Building this piece of software from scratch and releasing the code under GPL or similar or
b) You taking some Free source code and hacking on it to develop custom features for a specific enduser that won't be released into the wild
or c) Contributing patches to an already established project

In the case of "a", it will be up to the market and how mission critical the software is to the client and what that clients expectations are . Instant response via phone or in person is obviously going to be more expensive than 36 hour guaranteed email response .

The above applies to "b" as well, but with the additional proviso that it is no different to hacking on proprietary code .

and "c" will depend on your employer, if of course your employer has a policy about working on Open Source, if not then you do it in the quiet for free and come up with that really killer patch that has all the big development Houses beating on your door handing out really large salary packages or you win a prize at Google summer of code .

cheers
