Recording initial payments / expenses

How will I show payments made for creating my company, infrastructure and activities like web designing ?

Payments will be recorded under the Bank Accounts tab, using the Spend Money function. You will need to discuss with your accountant whether these must be capitalized or can be treated as ordinary expenses. The answer may depend on local tax laws.

Also, if payments were not made by the business, then use Expense claims tab which is to record expenses paid by someone else on behalf of the business.
