You can find your receipt/invoice within your job!
To view your invoices/receipts on submitted jobs with Taxfyle, this is now accessible within your job. When you're logged into the portal, click on your job, and on the left-hand side of the job page where you see Documents, Details, and Events, go to Details.
Then scroll down to the "Paid so far" section where you'll have a drop-down available to "View Receipts" showing the amount paid and the date/time the payment was made. When you click on the payment, your invoice will appear on a separate tab for what's been paid.
Pro Tip: Viewing receipts is only available for jobs that were submitted from 2020 on. If you submitted a job prior to 2020, receipts won't be available.
