**Overview**

You are an accounts payable associate for a large conglomerate company called Little Laboratories LLC. Little Laboratories has 22 subsidiaries, which offer a broad spectrum of services ranging from patent/legal and venture capital work to entrepreneurial R&D and other engineering-related pursuits. Despite the wave of invoices that you receive each week, you are the sole member of the accounts payable team responsible for processing them. After you process the invoices in the payables software, they are sent to the corresponding subsidiary’s executive for approval. Following approval, the system pushes the invoices into QuickBooks and prepares the bills for payment.

Each week, you review the invoices that haven’t been approved as of Friday at 5pm and send reminder emails to those that are responsible for approving them. Some executives are good at clearing out their approval queue before the end of the week and don’t require an email. Others fall behind and accumulate past-due invoices and late fees. Approvers with more than 2 past due invoices must be reported to Little Laboratories’ CFO.

Because you’re passionate about processing payables, you decide to build a workbook that streamlines the process. Assume that today is 4/14/2023. Your workbook should do the following:

- Generate a list of executives that need a reminder email
- Isolate a list of past-due invoices and corresponding detail
- Highlight the executives that are causing bottlenecks and late fees.

**Instructions**

- Download the excel file provided
- Find the Approver# of each executive that will need a reminder email. Starting in cell B3 of the
**EmailList**sheet, write a formula that will reference column G of the**RawData**sheet and display only unique values. - In cell C3 of the
**EmailList**sheet, write a formula that finds the email for the Approver# in cell B3. Copy the formula down so that emails are listed for each Approver# in the email reminder list. - In cell D3 of the
**EmailList**sheet, write a formula that finds the number of outstanding invoices that need to be approved by the Approver# in cell B3. Copy the formula down so that a total is listed for each Approver#. - Beginning in cells C3:I3 of the
**PastDueReport**sheet, write a formula that will reference the raw data and return only invoices that are past due. Assume that today is 4/14/2023. The solution uses a formula that can be written in cell C3, copied over to I3, and copied down to the extent of the past due invoices. - In cell L6, write a formula that sums the total number of past due invoices.
- In cell L7, write a formula that estimates the amount of late fees owed on the past due invoices. Assume that you can negotiate a late fee of 1.5% of the invoice amount with each vendor, regardless of how late the invoice is.
- Starting in cell K11 of the
**PastDueReport**sheet, write a formula that will reference the Approver#s in column I and display only unique values. - In cell L11 of the
**PastDueReport**sheet, write a formula that finds the number of past due invoices that need to be approved by the Approver# in cell K11. Copy the formula down so that a total is listed for each Approver#. - Highlight totals in excess of 2 that were generated in step 9.
