Simple way for Company A and B to pay Company C

I'm to help you track the transactions accurately, asellers03.

We can add Companies B, C, and D as items in QuickBooks Online. Then, let's associate them with the expense account. Here's how:

1. Go to Get paid & pay or Sales, then select Products & services.
2. Find the product or service on the list and select Edit in the Action column.
3. Select I purchase this product/service from a vendor.
4. Add a description. This shows on bills, purchase orders, and other forms you send to vendors.
5. Add the Cost. If the price changes, don’t worry. You can still enter the updated price when it’s time to buy supplies.
6. Select the Expense account drop-down and then the account you use to track the cost of things you sell.
7. Select your preferred vendor.
8. When you're done, select Save and close.

Once done, we can use the items when creating invoices for Company A.

To add the invoices to  Companies B, C, and D, we can import them into the program.

For the application, I'd recommend searching in our QuickBooks Apps Store which you can integrate with the program. 

Additionally, I've added an article that'll help you personalize your sales forms in QuickBooks Online. Doing so helps you add the details that matter most to the business: Customize Invoices, Estimates, and Sales Receipts.

Thank you, but unfortunately this doesn't help me at all. 

I'll take over and provide some insights about managing your companies, asellers03.

In QuickBooks Online, you can't have multiple companies in one subscription. That being said, we're unable to perform the task you've outlined. You can visit our QuickBooks App Store and find a third-party software that can code and pay costs to your businesses.

While I'm unable to dictate the specific application, I suggest consulting your accountant. If you don’t have one, here's how to find a ProAdvisor near your place.

1. Go to this link: https://quickbooks.intuit.com/find-an-accountant/.
2. Enter your address in the City or ZIP field.
   
3. Click Find a ProAdvisor.
4. Comply with the required fields, then click Search.
   
5. You'll then see recommended accountants. Click a profile and use the phone number to contact their office.

In addition to this, please know that each QuickBooks account has its own paid subscription. If you want to access them with the same sign-in info, this article will help you: Learn how to manage multiple company files.

Thank you for the reply.  Each company does have it's own subscription to QBO. They are all separate entities. 

In Company A - I have Company B set up as a customer with sub-customers set up for each project. 

When I enter a bill in Company A I mark them as billable, so I can go directly to the sub-customer (project) and select which billable expenses need to be invoiced to Company B. 

Then I move over to Company B books and enter the invoice Company A just made. Company B codes the invoice to products & services and the customer that the invoice is for.  This is where I am doubling up on my work. Since I have already done everything in Company A, is there a simple way to upload or sync costs to Company B's books? 

Is there an app that works with QBO that will allow me to upload a PDF of bills and allow the bill to be coded to products & services? I looked into Dext. It would work great if I only coded the invoices to Products and Services. I only found the one that only codes to expenses on the chart of account. 

I am just looking for a way to cut down the data entry time.

What's the relationship between the LLCs?  Is one of them the parent company?  Do they share 100% common ownership?  How are the entities taxed (sole proprietorships, S-corps, etc)?

Company A is owned by guy 1 & guy 2; Company B is owned by guy 1; Company C is owned by guy 2; Company D is owned by guy 1 & guy 2. They are all S-Corps. They started Company A to be a consulting/project management company. Eventually Company A will be billing other companies that want the service (I do not do the books for these other companies).  So right now Company B, C, and D get contracts to build a project. Company B, C, and D hire Company A to manage the project.
