Even if your target user thinks your tool is the greatest thing since sliced bread, do they have the authority to get out a company credit card and spend $10 on the spot?

Do people want to use a "beta" product for production work? (I assume very few people do GIS file conversions for fun.)

What happens if a customer gets a slightly different source file and needs to convert it again? Does that cost another $10? Instead of charging per-conversion, what if you offered a thirty-day "all-you-can-convert" plan?

In general, the website doesn't inspire confidence and it certainly isn't optimized for conversion. Payment information is lacking (yes, I see it's buried in your FAQ).
