When asked if SYMBOL can be modified to suit international markets, Metcalfe said it is best to keep it for Australia only.

"SAP is internationalized, but to achieve that they chose not to have a payroll system in it," he said. "Also BAS [Business Activity Statement] information is captured by SYMBOL and in a country with no BAS you have all this redundancy in the reports, not to mention the fact that SYMBOL would not be able to handle the overseas tax regime."

Metcalfe has not yet explored to possibility of integrating SYMBOL into another open source accounting or CRM system but said it does have the ability to provide a hyperlink from its transactions, which could feed into other Web-enabled databases.

For now, Metcalfe is SYMBOL's only developer and is hosting the project online at .
