An additional data attribute you add to a customer, contact, or opportunity such as a customer’s last login, the marketing campaign used to acquire them, or the name of their account manager to help with search, filtering, and segmentation. Read more about custom attributes in ChartMogul.

Custom Source

A specific type of source used to connect a non-supported billing system to ChartMogul. A custom source can also be used to import historical data, or when you have customers billed outside of your billing system. Import data using the Import API, CSV, or enter it manually. Each source must contain plan, customer, and invoice data for ChartMogul to calculate metrics and analytics correctly.

A document that records the sale of products/services to a customer and used to collect payment. Invoices have one or more invoice line items. Invoices can be open, paid, refunded, voided, or written off. ChartMogul uses invoice data to generate MRR calculations. ChartMogul classifies invoices as open, paid, or refunded based on an invoice’s transactions. Mark an invoice as voided or written off to exclude it from MRR calculations.

Invoice Line Item

Defines the product/service sold to and purchased by the customer. The type of each line item is either subscription (i.e., recurring) or non-recurring (one-time). When the type is subscription, the invoice line item includes a plan and a service period.


The status of a non-paying individual or company who may eventually become an active subscriber, including those on a free trial. Leads also include those who have only made non-recurring payments and do not have any subscriptions. ChartMogul has four lead statuses: New Lead, Working Lead, Qualified Lead, and Unqualified Lead. Learn about Customer & Subscription Statuses.

Lifetime Value

See Customer Lifetime Value.

The unit of time (day, week, month, quarter, or year) used to subdivide a chart’s reporting period into individual report intervals.

Monthly Recurring Revenue (MRR)

An estimate of the revenue earned each month from a product/service sold on a subscription basis. For monthly plans, MRR is the price paid for each month of the subscription. When a customer pays for more than one month up-front (e.g., 12 months), ChartMogul divides the amount paid for the subscription by the number of months in the service period. Learn more about Monthly Recurring Revenue.

A single or one-time purchase by a customer such as an add-on or setup fee. Specified as a non-recurring (in-app through the ChartMogul interface) or one time (via CSV or API) invoice line item. Non-recurring (one-time) purchases do not contribute to MRR.

Past due

The status of a subscription for which a payment or cancellation has not been received since the end of the subscription’s most recent billing period. A Past-due Subscriber has one or more past-due subscriptions. Learn about Customer & Subscription Statuses.


A transaction where cash has been received from the customer and the payment amount has been applied to an invoice.


A product/service (or set thereof) you offer on a subscription (recurring) basis, e.g., Gold Monthly Plan.

A discrete date range. In the context of a chart, one subdivision of the chart’s reporting period based on the chosen measurement interval. For example, a reporting period of January 1, 2022–March 31, 2022 with a measurement interval of month results in the following report intervals: January, February, and March (2022).

Reporting Period

The range of dates you establish for a chart when choosing a from and to date using the date range drop-down menu. Used in conjunction with the measurement interval to establish a chart’s report intervals.
