Frequently asked questions

How can I configure the alerts?

Alert configuration is only available with the new M plan. To configure alerts to suit you, log in to your InvoiceXpress account and go to Settings > Alerts. On this page you can change various alert settings: message texts, sending types (automatic or manual), timing, recurrence and channels (e-mail or SMS). You can also send alerts manually on each invoice page.

How much does it cost to send an alert?

Sending alerts is divided into two channels: e-mail and SMS. All plans have unlimited e-mails, but only the M plan or higher allows you to send SMS. Includes 20 free SMS per month (not cumulative), with the possibility of purchasing additional SMS packages at a very low cost. See the price list for the SMS packages above.

Can I customize the alerts for each customer?

Of course. In your account, simply go to the customer edit page to adjust the settings and messages in detail.

Is it possible to send alerts manually?

Yes. Whenever you wish, you can access an invoice individually and send an alert manually, by email or SMS.

Can I send SMS alerts to foreign numbers?

No. The SMS alerts feature is only available to Portuguese numbers, regardless of where they are in the world.
