Avoid Duplicate Customer Details in Invoice Tracker

In the video post about the Invoice Tracker I had shown how to track invoices, save customer details, invoice details and create a report. In the process it was noted that although unique company IDs were being created, duplicate customer details were being saved. Today we learn how to avoid duplicate customer details in invoice tracker and also optimize the code for wrapping text in a cell and placing the invoice total correctly. Watch the video and then study the VBA code carefully before creating your own invoice tracker:

Watch this video on YouTube.

Here’s the complete VBA code to avoid duplicates in customers worksheet. Module5 shows this step by step.


Public taxRate As Single
Public advance As Single
Public lastRow As Long

lastRow = wsInvoice.Cells.Find(What:=”*”, After:=Range(“A1”), LookAt:=xlPart, LookIn:=xlFormulas, SearchOrder:=xlByRows, SearchDirection:=xlPrevious, MatchCase:=False).Row

Dim i As Long

For i = 9 To lastRow
‘On Error Resume Next
Cells(i, 7).Value = Application.WorksheetFunction.IfError((Cells(i, 4).Value * Cells(i, 5).Value – Cells(i, 6).Value), “”)
Next i

lastRow = lastRow + 1

wsInvoice.Cells(lastRow, 6).Font.Bold = True
wsInvoice.Cells(lastRow, 6) = “Invoice Subtotal”
Cells(lastRow, 7).Value = Application.WorksheetFunction.Sum(Range(Cells(9, 7), Cells((lastRow – 1), 7)))

Welcome to exceltrainingvideos.com! My aim is to help you learn MS Excel including VBA. I always felt that a good way to learn something was to find solutions to problems in that domain. That is why I share these Excel videos with you. Mostly these are questions asked during my corporate training sessions. I've been training individuals and companies in computers since 1991. I did my B. Sc. (Vordiplom), M. Sc. (Diplom) and Ph.D. (Dr. rer. nat.) from Hamburg, Germany. The best thing about solving some of my visitor's questions is that I also gain new insights.
