This endpoint retrieves an existing customer.

Retrieve a customer

Configuration specific to the payment provider, utilized for billing the customer. This object contains settings and parameters necessary for processing payments and invoicing the customer.

The city of the customer's billing address

Country code of the customer's billing address. Format must be ISO 3166 (alpha-2)

The state of the customer's billing address

The zipcode of the customer's billing address

The document locale, specified in the ISO 639-1 format. This field represents the language or locale used for the documents issued by Lago

The grace period, expressed in days, for the invoice. This period refers to the additional time granted to the customer beyond the invoice due date to adjust usage and line items

The payment provider utilized to initiate payments for invoices issued by Lago.
Accepted values: `stripe`, `adyen`, `gocardless` or null. This field is required if you intend to assign a `provider_customer_id`.

Unique code used to identify a payment provider connection.

The customer ID within the payment provider's system. If this field is not provided, Lago has the option to create a new customer record within the payment provider's system on behalf of the customer

Specifies the available payment methods that can be used for this customer when `payment_provider` is set to `stripe`. The `provider_payment_methods` field is an array that allows multiple payment options to be defined. If this field is not explicitly set, the payment methods will be set to `card`. For now, possible values are `card`, `sepa_debit`, `us_bank_account`, `bacs_debit` and `link`. Note that when `link` is selected, `card` should also be provided in the array.

Set this field to `true` if you want to create the customer in the payment provider synchronously with the customer creation process in Lago. This option is applicable only when the `provider_customer_id` is `null` and the customer is automatically created in the payment provider through Lago. By default, the value is set to `false`

Set this field to `true` if you want to create a customer record in the payment provider's system. This option is applicable only when the `provider_customer_id` is null and the `sync_with_provider` field is set to `true`. By default, the value is set to `false`

Set of key-value pairs that you can attach to a customer. This can be useful for storing additional information about the customer in a structured format

The date of the metadata object creation, represented in ISO 8601 datetime format and expressed in Coordinated Universal Time (UTC). The creation_date provides a standardized and internationally recognized timestamp for when the metadata object was created

Determines whether the item or information should be displayed in the invoice. If set to true, the item or information will be included and visible in the generated invoice. If set to false, the item or information will be excluded and not displayed in the invoice.

A unique identifier for the customer metadata object in the Lago application. Can be used to update a key-value pair

The date of the customer creation, represented in ISO 8601 datetime format and expressed in Coordinated Universal Time (UTC). The creation_date provides a standardized and internationally recognized timestamp for when the customer object was created

The type of the customer. It can have one of the following values:

Specifies how invoices with a zero total amount should be handled:
- `inherit`: (Default) Follows the organization-level configuration.
- `finalize`: Invoices are issued and finalized even if the total amount is zero.
- `skip`: Invoices with a total amount of zero are not finalized.

Unique identifier assigned to the customer within the Lago application. This ID is exclusively created by Lago and serves as a unique identifier for the customer's record within the Lago system

The net payment term, expressed in days, specifies the duration within which a customer is expected to remit payment after the invoice is finalized.

The unique identifier assigned to the customer within the organization's scope. This identifier is used to track and reference the customer's order of creation within the organization's system. It ensures that each customer has a distinct `sequential_id`` associated with them, allowing for easy identification and sorting based on the order of creation

A concise and unique identifier for the customer, formed by combining the Organization's `name`, `id`, and customer's `sequential_id`

Lago is an open-source software for metering and usage-based billing. It's the best alternative to Chargebee, Recurly or Stripe Billing for companies that need to handle complex billing logic.

Welcome to Lago

Why billing is a nightmare

Deploy Lago seamlessly on your infrastructure, compatible with both free and premium editions.

Overview

Docker is the easiest way to get started with the self-hosted version of Lago.

Useful commands

Lago Cloud is the fully hosted version of our open-source billing API.

Billable metrics define how incoming events are aggregated in order to measure consumption.

Create billable metrics

Recurring vs metered

For more advanced calculations, you can use SQL custom expressions. These expressions are helpful when the aggregation results for a billable metric require complex calculations.

SQL Expressions

Lago aggregates your events in real time. You can add rounding rules to the final result.

Rounding

When setting up your pricing, you may want to filters events according to their property. To do so, you can create filters for your billable metric.

Filters

Delete billable metrics

If Billable metrics are made to measure customer usage, Plans are made to apply prices to this usage.

The plan model defines when and how much a customer is charged.

Plan model

Commitments

Progressive billing, also known as threshold billing, automatically triggers an invoice when a customer's cumulative usage reaches predefined thresholds. This method ensures that customers cannot exceed certain usage limits without ensuring payment is received, reducing the risk of unpaid services or fraud.

Coupons allow you to offer discounts to your customers. When you apply a coupon to a customer,  its value will be deducted from their next subscription invoice(s).

Coupons

A subscription is created when a plan is assigned to a customer.  You can assign a plan to a customer at any time (i.e. when the customer record is created or later on).

Assign a plan to a customer

Customers have the flexibility to easily upgrade or downgrade their plan at any given moment.

Upgrades and downgrades

You can edit a subscription at any time, whether it's active or pending.

Edit a subscription

You can terminate a subscription at any time, whether it's active or pending.

Add-ons are a useful feature that allows you to add a fixed charge that is not recurring to one-off invoices.  This can be used to apply one-time fees such as a setup fee, one-time payment, or customer success fee.

Create add-ons

One-off invoices allow you to bill immediately one or several add-ons to a customer.  This guide will show you how to create a one-off invoice for a specific customer using the add-ons.

Issue one-off invoices

This guide explains how Lago ingests usage-based events coming from your application.

Ingesting usage

By ingesting events, you can see them flowing in the Lago application by using the events list. It allows you to take a deeper look at ingested events and detect possible warnings.

Events list

Learn how to retrieve usage data for both current and past billing periods.

Retrieving usage

Here is a list of sources you can use to ingest usage data. Some of these sources are capable of handling up to 15,000 events per second with default settings.

Metering ingestion sources

Lago automatically generates invoices for each customer according to the plan model.

Fees

When generating invoices, you may need to apply vat or other taxes. By creating taxes and applying them to the organization or/and customers,  their invoices will be directly affected.

Connect Lago to any payment providers by using native integrations or webhook messages.

Lago's native integration with GoCardless allows you to collect payments via direct debit.

Dunning refers to the process of communicating with customers to remind them of overdue invoices and attempt to recover the outstanding amounts.

Manual dunning

Automate how to communicate with your customers to remind them of overdue invoices and attempt to recover their overdue balance using dunning campaigns.

Automatic dunning

Credit notes

Since usage-based charges can be calculated at the end of the billing period, you often need to wait to collect payments. With prepaid credits, you can now unlock recurring revenue opportunities for pay-as-you-go pricing models.
