With pleasure.
I sell my clients consultation contracts in various increments of 5 hours. I use Inventoria to keep track of the hours used on each contract and it works MUCH better than an Excel file PER client (what a mess).
In the "notes" field, I write what I did and some recommendations to improve network performance / stability. I e-mail a report to the client as a proof of what was done and they use it to keep track of remaining hours on the contract. But once the report is printed, you might loose a lot of information depending on how much I wrote.
Hope I was clear enough this time
Thanks
