# Accounts Receivable (AR)

> This guide helps Accounts Receivable companies automate the creation and reconciliation of invoices, invoice payments, invoice credit notes, and sales orders with their customers' respective accounting systems.

***

## Introduction

Accounting integrations play a pivotal role in bridging your automated Accounts Receivable (AR) solution with your customers' accounting systems. This document is a step-by-step guide that details the process of using accounting integrations (via RootFi' Unified Accounting API) to develop an automated Accounts Receivable (AR) product with reconciliation.

## What is the Accounts Receivable (AR) Workflow?

The AR workflow involves the following key steps:

1. **Invoice Generation**: Automatically create and send invoices based on services rendered or products sold.
2. **Payment Tracking**: Monitor incoming payments and match them against outstanding invoices.
3. **Reminders and Collections**: Send automated reminders for overdue invoices and manage collections for delinquent accounts.
4. **Reconciliation**: Ensure payments are accurately reflected in the accounting system.

Integrating with accounting systems is vital for automating these processes, ensuring that both invoices and payments are processed and reconciled accurately.

  <Step title="Connect with your customers' accounting platform (One-Time Activity)" titleSize="h2" stepNumber="1">
    RootFi provides two convenient options to connect with your customers' accounting platform:

    1. Use RootFi' **Connect Link**, a convenient and secure URL, **or**
    2. Embed RootFi' **Connect SDK** into your application

    The Invite Link requires no code, making it suitable to get started without a developer. You can customize and white-label this onboarding process with RootFi' Connect SDK, allowing authentication to occur natively in your product.

    Either way, your customers will be guided through a simple authorization flow to connect their respective accounting platforms to your product.

    1. Use our Dashboard or APIs to connect a customer's accounting platform. Use [**POST/invite-links**](/api-reference/v3/core/invite-links/create-invite-link), and provide a name for your customers' company.
    2. A unique `company_id` will be generated once your customer completes the authentication flow. This `company_id` will be used to read and write data to their accounting platform.

    **POST/invoice** to create an invoice.

    Important points to note while trying to post an Invoice:

    1. **Contacts**: This is the customer linked to the Invoice. Use [**GET/contacts**](/api-reference/v3/accounting/contacts/get-all-contacts) or [**POST/contacts**](/api-reference/v3/accounting/contacts/create-contacts). A `contact_id` is required to post an Invoice, so if the customer doesn't exist on the accounting platform, you'll first have to create a new customer using the [**POST/contacts**](/api-reference/v3/accounting/contacts/create-contacts).
    2. **Items**: Every invoice contains multiple items (either goods or services) that were sold as part of the invoice, each of which credits certain accounts depending on what comprises their cost of goods sold. [**GET/items**](/api-reference/v3/accounting/items/get-all-items) lets you fetch all items in the business entity's catalogue.
    3. **Sales/Purchase Order**: Some companies issue Sales or Purchase Orders before an Invoice is generated. Use [**GET/sales\_orders**](/api-reference/v3/accounting/sales-orders/get-all-sales-orders) to get the Sales Order ID, which can be passed in [**POST/invoices**](/api-reference/v3/accounting/invoices/create-invoices) to link the purchase order and bill.
    4. **Credit Account** (Not Required): When you use the [**POST/invoices**](/api-reference/v3/accounting/invoices/create-invoices), invoices are automatically placed under **account category = 'asset'** and **account type = 'accounts\_receivable'**.

  <Step title="Upload Documents (Recurring)" titleSize="h2" stepNumber="3">
    [**POST/documents**](/api-reference/v3/accounting/documents/create-documents) lets you upload a file to an expense, invoice, or bill. When posting a document you will be required to pass the feild `document_type_id`, which represents the `platform_id` that will be returned after you create a Invoice.

    ***
  </Step>

  <Step title="(Recurring): Link Invoice Payment and Credit Notes" titleSize="h2" stepNumber="4">
    An Invoice Payment debits an accounts receivable account and credits an asset account.

    1. Use [**POST/invoice\_payments**](/api-reference/v3/accounting/invoice-payments/create-invoice-payments) to create and link Invoice payments.

    The Invoice Credit Note can be created and immediately applied to a bill, or it can be created and left unapplied.

    1. An Invoice Credit Note can be created using the [**POST/invoice\_credit\_notes**](/api-reference/v3/accounting/invoice-credit-notes/create-invoice-credit-notes) and is linked to a Customer.
