Creating a new invoice
- 1
Navigate to Invoices in the left sidebar.
- 2
Click "New invoice" in the top right.
- 3
Select a client from the dropdown. If you haven't added the client yet, create them from the Clients page first.
- 4
Set an invoice date and a due date.
Adding line items
Line items represent the work or products you're billing for. Each line item has four fields:
Description - what the work or item is (e.g., "Brand strategy consulting", "Website redesign").
Quantity - the number of units, hours, or items.
Unit - an optional label for the quantity (e.g., "hrs", "days", "units").
Rate - the price per unit.
The line total and invoice total are calculated automatically.
You can add as many line items as you need. Use separate line items for different services, phases of a project, or expense reimbursements to give your client a clear breakdown.
Setting payment terms
Payment terms tell your client when payment is expected. Choose from common options like Net 15, Net 30, Net 60, or set a specific due date. The selected terms are displayed prominently on the invoice so clients know when payment is due.
Adding a client message
The message field lets you add a personal note to the invoice - for example, payment instructions, a project summary, or a thank-you note. This text appears on the invoice when the client views it.
Adding attachments
You can attach files to any invoice - scope of work documents, contracts, project deliverables, receipts, or anything else relevant to the bill. Attachments are visible to the client when they view the invoice in the portal.
- 1
Open the invoice (draft or sent).
- 2
Click the Attachments tab or section.
- 3
Upload files from your device.
- 4
Clients can view and download attachments from the invoice page.
Invoice statuses
Every invoice displays a status that reflects where it is in the payment cycle:
Draft - saved but not sent. Only visible to you.
Not Paid - the invoice has been sent or the link shared, awaiting payment.
Partial - some payment has been received but a balance remains outstanding.
Overdue - the due date has passed without full payment.
Paid - the invoice is fully settled.
Sending the invoice
Once your invoice is ready to go, you have two options:
Copy link - copies a unique URL for the invoice. Paste this into any email or message to your client.
Send email - delivers the invoice directly from WaffleInvoice using your configured email settings. Clients receive a professional email with a link to view and pay. Free accounts get 25 invoice email sends per rolling 30-day window (plus a 5/day cap for the first 14 days). Pro removes both caps.
No card is required to send invoice emails on the free plan. A card is only requested when you want to accept online payments (connect Stripe) or upgrade to Pro.
Editing an invoice
You can edit a draft invoice freely. Once an invoice has been sent, editing it will update the invoice that the client sees - useful if you need to correct an error or add a line item. The client's invoice link always shows the latest version.
Duplicating an invoice
To quickly create a new invoice based on an existing one, use the Duplicate option from the invoice actions menu. This copies all line items, terms, and client details into a new draft so you don't have to rebuild it from scratch.
Recording a payment
When a client pays by cash, check, or bank transfer, mark the invoice paid manually:
- 1
Open the invoice.
- 2
Click "Record payment".
- 3
Enter the amount received and the payment date.
- 4
Add a note if needed (e.g., "Check #1234").
- 5
Save. The invoice status updates automatically.
For online payments (card and ACH), WaffleInvoice handles payment tracking automatically. Once a client pays through the invoice link, the invoice is marked paid and you receive a confirmation email.
