A collection in Gravv is a mode of receiving payments into an [internal account](/platform/accounts/overview#internal-accounts), internal crypto wallet, and external crypto wallet. The collection process generates a payment link for card collections and payment instructions for mobile money and bank transfers.

## Collection flow

The collection flow is as follows:

* [create a customer](/getting-started/your-first-gravv-integration#create-a-customer) to obtain a customer id
* initiate a [Know Your Customer (KYC)](/getting-started/know-your-customer) verification process
* [create an account](/platform/accounts/create-an-account) to hold the funds
* make a collection request using one of the [collection methods](/platform/collections/collection-methods/overview)
* receive a payment instruction in response and display it to the customer
* customer completes the payment by following the instructions
