According to the billing cycle you have chosen for your services, you receive auto-notifications from SigmaWeb. Payment methods available are: credit cards, paypal, bank deposits. 
For your own convenience, SigmaWeb has developed a user friendly Client area with ideal potentials, enabling each customer to manage his account, his purchases, renewals, upgrades or payoffs. This is why you don't need an operator's advice for issues mentioned above and that's also the reason we offer our high standard services in such low prices. We advice you redeem your proforma invoices in time, so as to avoid your account being suspended or even canceled or being charged with extra fees.
