How many servers/clients are you trying to inventory?
We recently partnered with Patchlink, a provider of patch management software. We were pleasantly surprised to find that their patch software has built-in inventory functions that can show you everything, including what software/versions are loaded on each ssytem. The inventory can be easily exported to Excel.
The pricing is based on volume. I think it lists for around $10-$15/license but we sell it for much less. There is server software required, it runs around $1000 (one time).
