Understand Merchant Limits
Last updated on Sep 9, 2026
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 merchant categories
Advanced Billing merchants are categorized into the following three categories:
- Canceled Merchants: Previously paying us but have since stopped paying.
- Developer Account Merchants: Free accounts with only test sites.
- Paying Merchants: Current customers subscribed to paid plans.
Paying merchants
If you are an active merchant with Maxio, you are categorized into two different subsections. Each subsection has different guarantees for your data.
- Live sites: Your live sites are processing real transactions and are connected to a live gateway.
- Test sites: These are “free” additional sites that we encourage merchants to use to test their pricing models and develop new sites. Your test sites will be held to stricter data retention policies. In other words, since your test sites are for research purposes, Advanced Billing will periodically purge data from your test sites.
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.
Developer account data retention rules
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.
Canceled merchant data retention rules
In the event your Advanced Billing account is canceled, we will retain your data for 60 days after the cancellation date.
- If you contact us within 60 days of the cancellation of your account, we will be able to restore your account and resurrect your existing Site data.
- After 60 days, your account will be purged from the system and the data will be unavailable for retrieval.
Overview of limits
Test sites
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.
Live sites
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.
API limits
For more information on Advanced Billing’s rate limits and blocks for all endpoints, please see our API rate limiting documentation.
Emails
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.
Test site emails
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.
Test site subscriptions
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.
Users
Paid Plan Users: Paying merchants are limited to 1,000 users per account.
Developer Plan Users: Sellers are allowed to create up to 10 users.
Webhooks
- Advanced Billing retains webhook information in your Site’s webhook panel for 90 days. All activity after 90 days is purged from our system.
- If your webhook endpoint stops responding, Advanced Billing retries every 2 hours. After 25 consecutive failures it stops queueing new webhooks, and after 50 it disables the endpoint entirely.
