TORONTO (TheStreet) -- Billing customers and collecting payments are some of the biggest chores for small-business owners.

Gone are the days when invoices were created and sent by snail mail. Now, it seems like everyone has jumped into the accounts-receivable game, from client management specialist NetSuite (N) (Stock Quote: N) to payroll services provider Paychex (PAYX) - Get Report (Stock Quote: PAYX). Even giants like American Express (AXP) - Get Report and Bank of America (BAC) - Get Report offer billing tools.

To find out what the remaining field looks like for small businesses trying to bill smarter, I tested FreshBooks, a Toronto-based invoicing service. It's free to start, but full-service packages run $150 a month. Most small businesses should expect to pay $29 a month.

Simply head to FreshBooks' Web site, enter some basic company information -- no complex tax data or sensitive details are required -- and in three minutes you will have a page with tabbed categories, such as clients, team, estimates and expenses.

(N) (PAYX) - Get Report (AXP) - Get Report (BAC) - Get Report (INTU) - Get Report (MSFT) - Get ReportWhat you don't get: FreshBooks isn't a comprehensive accounting program, not does it integrate easily with your existing IT architecture.

All the the data-entry screens are simple, but they still require you to enter information manually. It's possible to import and export data, but task lists aren't easy to transmit.

(N) (PAYX) - Get Report (AXP) - Get Report (BAC) - Get Report (INTU) - Get Report (MSFT) - Get Report While FreshBooks offers an open API that allows developers to adapt the program to their systems, software support is limited. For example, the only project management tool that worked with my test program was Basecamp, from Chicago-based 37signals.

And then there's the 800-pound gorilla in the room: your accountant. Your bean counter is probably accustomed to Intuit's QuickBooks. That means your accountant might need to redo your ledgers manually in QuickBooks if you rely on FreshBooks. That's likely to make him or her cranky at tax time.

It's fast. It's easy. It sends professional-looking invoices. But you will eventually outgrow it, and move on to QuickBooks.
