Configure tax and VAT Tax is worked out from the client's billing address when an invoice is generated. Decide inclusive or exclusive first: changing it later changes every price.
Can WBAMS charge tax or VAT? Yes. Two levels of tax rules by country and state, inclusive or exclusive pricing, compound tax, VAT number validation for business clients, and your tax number on every invoice.
Does payroll calculate tax? Yes, from the tax tables you enter for each country and region, band by band. WBAMS ships no tables of its own: a country with no table in force is not taxed, and the pay run says so before you approve it.
