How much should I charge someone who wants me to install/modify an OSCommerce online shopping cart?

Posted on December 26th, 2009 by admin

I had someone offer me a job to install an online shopping cart (I have previous experience with OSCommerce) as well as modify the template/theme to resemble their main site. They also want me to post pics, details, and prices for about 50 products. I don’t even know where to begin with how much I should charge… This could take anywhere from 10-20 hours

That sounds like a lot more than 10-20 hours work. How much you charge depends on a few factors –

1. How eager you are to gain the work
2. How busy you are with other work, i.e is this work expendable?
3. How much you think the client is willing to pay
4. How much you think the job is worth / how much time involved
5. How much you think other developers would charge

Unfortunately there are no hard and fast rules and I wouldn’t listen to an established freelance developer if you are just starting out and want to gain the work.

Figure out an appropriate hourly rate, guestimate your hours, and calculate your project costing on that basis. Freelancers will often add a small 10-15% increase to act as a buffer for all the stuff that was not anticipated, e.g. testing, bug fixing, tweaking, last minute client amends etc.

Then take this final figure and run it by the above questions to check that it seems OK on each front. When you’re happy, pass this value onto the client.

    Do them a favor.. and use cre loaded.. a much more powerful cart than OSC

    You can charge what the market pays.. and I suggest doing an hourly scale as you have no idea how much time porting the existing theme is going to take.. along with the products
