Limits are the primary ways that we protect Advanced Billing from attack, overuse, and abuse. Our limits are designed to keep Advanced Billing running smoothly for all merchants and for your potential subscribers.
Our #1 goal is to not create any noticeable impact on users of Advanced Billing. This is especially in the case when our merchants use the systems as designed. If merchants reach these limits, they will be notified in-app that the limit has been reached.
Advanced Billing merchants are categorized into the following three categories:
If you are an active merchant with Maxio, you are categorized into two different subsections. Each subsection has different guarantees for your data.
Please pay close attention to what category you fall into while you use this guide. Additionally, as your sites transition from test to live, please be aware that the limits will shift.
If your developer account has been inactive for 90 days, the owner email associated with the account will receive a warning. After 120 days your account will be purged from the system. As a reminder, when your account is purged, your account is erased completely from the system and not recoverable.
To retain your account, your account must retain an “Active” status. For your account to be considered “active” you must actively log into your account. Accessing your information via API is not considered logging in and will not count towards maintaining an active status.
In the event your Advanced Billing account is canceled, we will retain your data for 60 days after the cancellation date.
All sellers, regardless of plan, are allowed to have up to 10 test sites.
For test sites, which are not live, the following limits are enforced. We’ve provided some examples below that indicate how these limits are applied to your test site.
Test sites are limited to:
| Item | Limit |
|---|---|
| Products | 500 |
| Customers | 500 |
| Subscriptions | 500 |
| Coupons | 500 |
| Components | 10,000 |
| Metafields | 50 |
As an example, a single test site could hold 500 products and 500 subscriptions at the same time, because each limit is counted separately.
There is no limit on the number of LIVE/Production Sites a merchant can have.
Each live site is limited to:
| Item | Limit |
|---|---|
| Products | 11,000 |
| Components | 10,000 |
| Metafields | 100 |
| Custom price points | 30 |
Live sites have no limit on the number of subscriptions, customers, or coupons.
For more information on Advanced Billing’s rate limits and blocks for all endpoints, please see our API rate limiting documentation.
Advanced Billing will retain email history for all your sites for up to 95 days. Any emails delivered more than 95 days ago are purged from the system.
Sites set in test mode have a limit of 100 emails sent per rolling 24 hour period. Any emails sent after the limit is reached will still be in the email archives where the contents can be viewed. They will appear with the status overlimit.
Subscriptions on your test sites have a limited duration of approximately six months. After that, subscriptions are automatically cancelled so that they’re not left “fake billing” indefinitely. You may re-activate a test subscription that has been automatically canceled, and it will remain active for another six months before being canceled again.
Paid Plan Users: Paying merchants are limited to 100 users per account.
Developer Plan Users: Sellers are allowed to create up to 10 users.
