couple more small copy suggestions:
- In large top image of dashboard, tab says "Reccuring" ("Recurring")
- "security right out-of-the-box" (not typically hyphenated)
- "Custom to-do's lists" ("to-do lists")
- "Integrated per-transaction pricing we don’t charge different rates for different credit cards." Should there be a period after "pricing"?
- you don't have consistent usage of the serial comma (or lack thereof)
- "...designing OpenUnit from the ground-up" (not hyphenated)
