A simple payroll manager.
Owners can:
- Add or remove employees;
- Manage employees salaries;
- Check payroll burnrate;
Employees can:
- Allocate their salaries in allowed ERC20 tokens;
- Update account addresses;
- Withdraw salaries monthly;
Payroll base currency.
Install Node v8.9.1^
Install project dependencies:
$ npm install
Compile contracts:
$ npm run compile
Run migrations:
$ npm run migrate
The script scripts/test.sh creates a local network and calls Truffle's tests.
Type
$ npm test
for running tests.
Truffle console can be used to interact with PayrollManager. For example:
$ truffle console --network dev
truffle(custom)> PayrollManager.deployed(); // ...

Deal with Date/Time in Solidity is a way far from an optimized and precise solution. A trusty Oracle can be added to retrieve dates and optimize employee's time locks treatment.
-
The Oracle responsible for updating token exchange rates is just illustrative. Solutions such as Oraclize can be used for integrating the Smart Contract with a real-world API and fetch token rates correctly.
-
Solidity tests will be necessary in the future, when considering functions with non-trivial returns. This is a limit of JavaScript tests.

The solution was built to distribute employee's salary in ERC20 Tokens: partially in EUR and other tokens, completaly in EUR or in other tokens. The possibility for including ETHER in the distribution would be great.
