On Android through Google Play

Choose a plan

Open Street Invoice on your Android device and sign in to the account you want to manage.
Open Settings and tap My Street Invoice Plan.

Choose monthly or annual billing, then tap the option shown for that plan, such as Subscribe, Choose, or Switch plan.
Review the price, billing period, and terms shown by Google Play. Confirm the purchase in Google Play.

Google Play handles payment for new Android subscriptions. Paid Play plans renew automatically at the displayed price and billing period unless canceled in Google Play or in Street Invoice. Google Play subscriptions for Street Invoice do not currently include any coupon codes or or promotional offers.

Changing an existing Google Play plan

An upgrade takes effect immediately, and Google Play calculates and displays the prorated price difference. A downgrade to a lower tier takes effect at renewal, so your current tier remains in place until then. A monthly/annual billing change within the same plan uses no proration; review the effective date and next charge shown by Google Play before confirming.

If you already have a non-Play plan

If your Street Invoice account is already billed outside Google Play, do not start a second Google Play subscription. Contact Street Invoice Support for help with an existing billing arrangement.
