If price is your primary criterion, you can't beat the selection of free accounting software currently available for both personal and business use.
The most popular free personal solutions are Wave and Mint though you can find a number of other options by taking a look at our review of the best online personal accounting software.
As for business, at least one of the products mentioned in our list of the best free small business accounting software should suit your needs.
Marko, If you've outgrown an entry-level accounting system, such as QuickBooks, are at least a 30-employee company, and need robust software, then Intacct should be on your list. Voted by Inc. Magazine as the "Best to Replace QuickBooks," and the only Cloud product (I believe), endorsed by the AICPA, its comprehensive features are second to none. See my latest post (should be up soon) for a discussion of best value for online accounting in terms of functionality and total cost of ownership.
