How to Create an Invoice in Slash
Last updated April 9, 2026
Overview
Slash's invoicing feature lets you request payments from clients and customers by generating professional invoices directly from your dashboard. When you create an invoice, your customer receives an email with the invoice PDF and a secure payment page. This guide walks you through the step-by-step invoice creation flow.
How to Create an Invoice
Step 1: Create a New Invoice
From your Slash dashboard:
- Navigate to the "Invoicing" page on the sidebar
- Click "New Invoice" in the upper-right corner
- You'll be taken to a guided, multi-step invoice creation flow

Step 2: Select or Add a Customer
Use the search bar to find an existing contact or vendor. Select one to continue. If the customer doesn't exist yet:
- Click "Add new customer"
- Enter the customer's legal name, email, and nickname
- (Optional) Add address information
Once saved, the customer's details will appear on the left. Click "Select Customer" to continue.

Step 3: Add Invoice Details
The Invoice Details section lets you build the content of your invoice. Each invoice comes with an auto-generated ID that you can edit.
For each line item, enter:
- Item name
- Quantity
- Unit price
After you add all line items, you can also apply a fixed or percentage discount, as well as add a percentage sales tax.
The invoice preview on the right will update automatically to show a preview of the final invoice.

Step 4: Set Payment Details
On this screen, you can specify when and where payments should be deposited.
- Issue Date: defaults to today, but can be changed
- Due Date: choose when payment is expected
You can also specify which Slash account should receive the invoice payment. Your business banking details (such as bank name and address) will automatically populate in the invoice preview.
You can also add an optional memo field to clarify terms or provide references.
When finished, click "Continue to Review".

Step 5: Review Your Invoice
Before finalizing, you'll see a complete preview of the invoice exactly as the customer will receive it. Carefully review all details. If anything needs adjustment, click Back to update previous steps.
When everything looks correct, click Create Invoice. This will send an email to your customer, including the PDF of the invoice as well as a payment page.

After Creating an Invoice
Once created:
- The invoice will appear in your Invoicing dashboard
- From there, you can track every invoice or share the invoice link
- Each invoice will display its status (Paid, Unpaid, Overdue, or Void), along with due dates and payment amounts
