Are you a civil engineer? Or are you involved in construction work in any way? And are you looking for an ideal interim payment certificate format? If the answers to the above questions are yes, then you’ve come to the right place. In this article, you’ll learn how you can create an interim payment certificate format effectively in Excel with appropriate illustrations.

What Is an Interim Payment Certificate?

Before going into the details, let’s dwell a little on what an interim payment certificate is. In easy words, any certificate of payment issued by the engineer that is not the “Final Payment Certificate” is referred to as an “Interim Payment Certificate”. When a contractor gets a project, they don’t get the whole contract amount at a time. Actually, they get it part by part after completing a successful percentage of the work. This is the interim payment. This refers to everything except the final payment.

6 Steps to Make Interim Payment Certificate Format in Excel

This section focuses on how we can construct an interim payment certificate format in Microsoft Excel. Here, we’ll show you the different steps involved in the process of making this payment certificate. To create multiple parts of the payment certificate format, follow the approach step by step.
Here, we have used the Microsoft Excel 365 version, you may use any other version according to your convenience.

Step 01: Create Basic Outline

At the very beginning, we’ve to build a basic outline where the basic information of this certificate can fit in. Let’s see the process in detail.

📌 Steps:

  • First of all, give a suitable heading in the B2:G2 range. In this case, we’ve done it as Interim Payment Certificate.
  • Then, in the B4:G7 range, create an area to insert the basic data and information about the project. This includes the Project Name, Contractor name, Contract Amount, etc. This part gives us a clear idea about the project.

Step 02: Mention Work Details and Bill Quantity

There are multiple types of tasks associated with construction work. Also, a separate payment arrangement is specified for each job. It’s simple and easy. Just follow along.

📌 Steps:

  • At first, create a table in the B9:E16 range.
  • In the B9:E9 range, give the different headings of the column. Here, we did it as SL, Description, and BQ Amount (bill quantity).

Mention Work Details and Bill Quantity

  • Secondly, place the first work name and short description in cell C10 and put its corresponding bill amount in cell E10.

  • Similarly, write down the other function’s name of this project in Column C and their respective BQ Amount in Column E.

Step 03: Acknowledge Percent of Work Completion

In a payment certificate, how much percentage of the work has been completed should be mentioned. Based on this, the payment amount will be verified. So, without further delay, let’s see how to do it.

📌 Steps:

  • At this time, create a new column with the heading % Complete under Column F.
  • Then, in cells in the F10:F16 range, write down the completion percentage of each work in order.

Step 04: Calculate the Total Due Amount

In this section, we’ll calculate the bill’s due amount based on the percentage of completion. It’s the most important part of this certificate. So, without further delay, let’s dive in!

📌 Steps:

  • Firstly, create a new column for Due Amount.
  • In this column, select cell G10 and enter the following formula into the Formula Bar.

Basically, this formula multiplies the total bill amount in cell E10 with the completion percentage in cell F10 to get the due payment amount.

  • After that, press the ENTER key.

Calculate the Total Due Amount

  • Now, bring the cursor to the right-bottom corner of cell G10, and immediately, it will look like a plus (+) sign. Actually, it’s the Fill Handle tool.
  • Then, double-click on it to copy the formula to the following cells.

Using the Fill Handle tool

Instantly, the cells in the G11:G16 range get filled with the correct results.

Calculate the Total Due Amount of interim payment certificate format in excel

Currently, we’ll enumerate the grand total of the due amount. To do this,

  • Primarily, go to cell G17 and write down the formula below.

Here, we’ve used the SUM function in this formula. It computes the required amount for various types of work in cells in the G10:G16 range.

  • As usual, press ENTER.

Step 05: Compute the Due Amount for the Present Payment Certificate

In the previous section, we talked about the total due amount. Here, we’ll show how to calculate the due amount for the present payment certificate. As here we are working with the second interim payment certificate, the payment for the first one must be done. Let’s see it in action.

📌 Steps:

  • Initially, we’ll introduce two items: 10% retention and previous payments. Here, retention means holding up some money for security purposes. Ideally, we took it as 10%. Since it is the second interim payment certificate, the number of previous payments should be 1.

Compute the Due Amount for the Present Payment Certificate

  • Presently, go to cell G20 and put the following formula into the cell.
  • As always, press ENTER.

Present Due Amount of Interim Payment in Excel

Additionally, we can display this amount in cell G20 in words. To do this,

  • Firstly, create a range in cells in the B22:G22 range.

  • After that, go to the Developer Tab .
  • Then, click on Visual Basic in the Code group.

Opening Visual Basic

Immediately, it opens the Microsoft Visual Basic for Applications window.

  • Now, move to the Insert tab.
  • Later, select Module from the available options.

Inserting Code Module

Suddenly, it opens a code module where we can write down our code to make it work.

  • Following this, copy the following code and paste it into your code module.
Function ConvertCurrencytoWords(ByVal GivenCurrency)
Dim USD, C
Words = Array("", "", " Thousand ", " Million ", " Billion ", " Trillion ")
GivenCurrency = Trim(Str(GivenCurrency))
FractionCurrency = InStr(GivenCurrency, ".")
If FractionCurrency > 0 Then
C = TensPlace(Left(Mid(GivenCurrency, FractionCurrency + 1) & "00", 2))
GivenCurrency = Trim(Left(GivenCurrency, FractionCurrency - 1))
End If
GetIndex = 1
Do While GivenCurrency <> ""
GetHundred = ""
GetValue = Right(GivenCurrency, 3)
If Val(GetValue) <> 0 Then
GetValue = Right("000" & GetValue, 3)
If Mid(GetValue, 1, 1) <> "0" Then
GetHundred = OnesPlace(Mid(GetValue, 1, 1)) & " Hundred "
End If
If Mid(GetValue, 2, 1) <> "0" Then
GetHundred = GetHundred & TensPlace(Mid(GetValue, 2))
GetHundred = GetHundred & OnesPlace(Mid(GetValue, 3))
End If
End If
If GetHundred <> "" Then
USD = GetHundred & Words(GetIndex) & USD
End If
If Len(GivenCurrency) > 3 Then
GivenCurrency = Left(GivenCurrency, Len(GivenCurrency) - 3)
GivenCurrency = ""
End If
GetIndex = GetIndex + 1
Select Case USD
Case ""
USD = "No USD"
Case "One"
USD = "One Dollar"
Case Else
USD = USD & " USD"
End Select
Select Case C
Case ""
C = " and No C"
Case "One"
C = " and One Cent"
Case Else
C = " and " & C & " C"
End Select
ConvertCurrencytoWords = USD & C
End Function
Function TensPlace(TensDigit)
Dim Output As String
Output = ""
If Val(Left(TensDigit, 1)) = 1 Then
Select Case Val(TensDigit)
Case 10: Output = "Ten"
Case 11: Output = "Eleven"
Case 12: Output = "Twelve"
Case 13: Output = "Thirteen"
Case 14: Output = "Fourteen"
Case 15: Output = "Fifteen"
Case 16: Output = "Sixteen"
Case 17: Output = "Seventeen"
Case 18: Output = "Eighteen"
Case 19: Output = "Nineteen"
Case Else
End Select
Select Case Val(Left(TensDigit, 1))
Case 2: Output = "Twenty "
Case 3: Output = "Thirty "
Case 4: Output = "Forty "
Case 5: Output = "Fifty "
Case 6: Output = "Sixty "
Case 7: Output = "Seventy "
Case 8: Output = "Eighty "
Case 9: Output = "Ninety "
Case Else
End Select
Output = Output & OnesPlace(Right(TensDigit, 1))
End If
TensPlace = Output
End Function
Function OnesPlace(OnesDigit)
Select Case Val(OnesDigit)
Case 1: OnesPlace = "One"
Case 2: OnesPlace = "Two"
Case 3: OnesPlace = "Three"
Case 4: OnesPlace = "Four"
Case 5: OnesPlace = "Five"
Case 6: OnesPlace = "Six"
Case 7: OnesPlace = "Seven"
Case 8: OnesPlace = "Eight"
Case 9: OnesPlace = "Nine"
Case Else: OnesPlace = ""
End Select
End Function

VBA Code

Step 06: Construct Certification and Authorization Space

Now, we’ll create a separate section to express the consent of both parties. So, let’s see it.

📌 Steps:

Here, we built an isolated area in cells in the B24:G36 range. In this section, they can give their opinions and signatures.
