Can I add the vendor name on my invoice for each expense that is listed on the invoice?

A vendor invoice is a your bill, he is invoicing his customer

The bill when entered has the vendor name on it, then you enter the expenses you paid for.  So they are associated with each other.  You can run purchase reports by vendor or by item/expense if you need to

So there is no reason to list the vendor for each expense, no you can not do it to answer the question directly

Hello there, @welcometoyourhom1.

Yes, you can add a vendor's name on an invoice. There are three ways on how to do this, depending on your preferred option.

The first is to add a custom field on your invoice template by clicking on the Gear icon at the top and enter the vendor name. Please see the screenshot attached for your reference:

The second is to add the vendor's name on the description field on the invoice. I've included a snip below for a visual guide: 

The third one is to enter the vendor's name fro the message section on the invoice. Please check out the sample snip below for reference:

This is clearly a non answer. Being able to add one vendor name to a customer field or manually in the description on the invoice, or message at the bottom of the invoice is not a reasonable solution. Especially not when a single invoice might have 100 different vendors. 

Neither is running separate reports just so I can show the vendor name of my expenses to my client. That requires me to send a separate PDF in a separate email(since there's no option for attachments when mailing a QB invoice), just so that my client will know who I purchased materials and labor from. This is imperative and a financier and client requirement when constructing custom homes. 

There is zero reason we shouldn't be able to include a column on the invoice for the vendor name for each line item of the invoice. What could it possibly hurt for that to be an option? Just because there's complex and time consuming ways to get around this mysterious omission, doesn't mean it shouldn't be remedied immediately. I pay $150/month for this software and the little things are never fixed.

Well said! I agree 100%

Agreed! I currently run reports to Excel for billed costs and then copy and paste the vendor names on each reimbursed expense line item for my customer. It is time-consuming and tedious.

my only solution is when I am entering bills, I enter the vendor name in the "description" part of the bill.  It's the only way I've found as a work around which is SO strange to me.  Why can we not have the vendor name appear when we choose the CREATE INVOICES - ADD TIME AND COSTS feature.  I'm a home builder as well and my clients want to know who the vendors are each month on the invoice I send them.   This needs to be fixed.
