# Your first invoice

Bill a client from start to finish. Create the invoice, add the service and its price, confirm it to give it a number, find how it is sent, then record the payment that marks it paid.

A customer invoice tells a client what they owe for a service and when to pay it. This walk-through bills a legal consultation to a client, from the empty invoice to the moment it is paid, on the screens a finance team uses every day.

## Before you start {#before-you-start}

- You need the **Invoicing** access right on **Accounting** for all documents, or **Administrator**. The access rights are explained in [How customer invoices work](how-customer-invoices-work).
- The client exists as a contact. The example uses **Saffron Dune Trading Co.**, a client of the demo data.
- The service exists as a product. The legal apps install **Consulting Fees**, **Case Fees**, **Hearing Fees**, **Contract Fees** and **Execution Fees**, each with the sales tax of the company.

## Step 1: open the invoices {#open}

Open **Accounting/Customers/Invoices**. The list holds the customer invoices and the credit notes of the company: the **Number**, the **Customer**, the **Invoice Date**, the **Due Date** (shown as "In 30 days" or "9 days ago" while it is unpaid), the amounts and the **Status**. A draft has no number yet and shows a slash.

Click **New**.

## Step 2: the client and the terms {#client}

1. In **Customer**, type the first letters of the client's name and pick it from the list. The address of the client appears under the name.
2. Leave **Invoice Date** empty: it shows **Today** and takes the date of the day you confirm the invoice. Type a date only to issue the invoice with an earlier or later date.
3. Next to **Due Date**, choose the **Payment Terms**, here **30 Days**. The terms compute the due date from the invoice date, and the field is then called **Payment terms**. Without terms, type the due date yourself.

The **Journal** is **Sales** and the currency is the company's. Change them only for a client billed in another currency or through another sales journal ([Create a journal](/docs/accounting-start-here/create-a-journal)).

## Step 3: the service {#line}

1. In the **Invoice Lines** tab, click **Add a line**.
2. In **Product**, search for the service and pick it: **Consulting Fees** in the example. The account, the quantity of 1 and the tax of the product are filled in.
3. Type the fee in **Price**, here 1,500.00. The legal fee products carry a price of 1.00, so the fee agreed with the client is typed on each invoice.
4. A description can go under the product: it shows as a box under the product name, or behind the lines icon at the end of the product when the client reads the same language as you. Type, for example, "legal consultation on the lease dispute". It is printed under the product name on the invoice.
5. Click the cloud icon **Save manually**.

![The service line with its price and tax, and the totals below.](https://jaah.app/web/image/9792-51226e01/customer-invoices-first-invoice-invoice_line-en.png)

Under the lines, the totals show the **Untaxed Amount**, the tax of each rate and the **Total**. To take an amount off the whole invoice, use **Total Discount** above the totals: see [Give a discount on an invoice](give-a-discount-on-an-invoice).

## Step 4: confirm {#confirm}

Open the **Actions** menu and choose **Confirm**. The invoice receives its number, made of **INV**, the year and a counter, and its status becomes **Posted**. From now on the lines, the amounts and the client are locked; the entries of the invoice are in the books.

![The confirmed invoice has its number and the status Posted.](https://jaah.app/web/image/9796-8adff2e5/customer-invoices-first-invoice-invoice_posted-en.png)

A mistake after this point is corrected with **Reset to Draft**, which reopens the invoice with the same number, or with a credit note: see [Issue a credit note](issue-a-credit-note).

## Step 5: send it {#send}

The **Actions** menu of a confirmed invoice holds **Send**, **Print**, **Pay**, **Preview** (the invoice as the client sees it in the customer portal), **Credit Note** and **Reset to Draft**.

![The Actions menu of a confirmed invoice, with Send, Print and Pay.](https://jaah.app/web/image/9800-4ff153dc/customer-invoices-first-invoice-invoice_actions-en.png)

On a phone, the **Actions** button sits at the top of the screen, next to the plus button.

**Send** e-mails the invoice with its PDF to the client: [Send an invoice by e-mail](send-an-invoice) shows the e-mail and its template. **Print** downloads the PDF without sending anything.

## Step 6: record the payment {#pay}

When the client pays, open the **Actions** menu and choose **Pay**. The window proposes the **Bank** journal, the amount still due and today's date. Check them and click **Create Payment**.

![The payment proposes the bank journal, the amount due and today's date.](https://jaah.app/web/image/9802-a8d51b2d/customer-invoices-first-invoice-invoice_pay-en.png)

A green **Paid** ribbon covers the corner of the invoice, the payment is listed under the totals with its date, and the **Amount Due** is zero. The **Payments** button at the top opens the payment.

![The invoice is paid; the Payments button opens the payment.](https://jaah.app/web/image/9806-59691f68/customer-invoices-first-invoice-invoice_paid-en.png)

The payment is then matched with the line of the bank statement that shows the money arriving. That matching belongs to [Banks, cash and currencies](/docs/banks-and-cash).

## What you have done {#what-you-have-done}

You created an invoice for a client, gave it a service and a price, confirmed it, saw where it is sent from, and recorded its payment. The user guide takes each task further: [Record a customer payment](record-a-customer-payment) (partial payments and credits), [Issue a credit note](issue-a-credit-note), [Give a discount on an invoice](give-a-discount-on-an-invoice), [One payment link for several invoices](one-payment-link-for-several-invoices), [Send an invoice by e-mail](send-an-invoice) and [Customer invoice settings](customer-invoice-settings).
