Change Orders are a fact of life that a contractor must deal with on just about every construction project that they are involved with.
Construction contracts start with an original bid amount for specific cost codes, phases of work, or line items. However, most construction contracts change as work proceeds; resulting in both increases and decreases or positive and negative change orders – which affect the original bid amount.
There are many ways in which people will handle Change Orders when using QuickBooks, such as just going to the original Estimate and changing the dollar amounts of the affected items. This is a “quick and easy fix”; however, it doesn’t leave a good documentation trail for what occurred on the project and can cause a lot of confusion.
Handling change orders that increase the value of the contract can be accomplished by:
- Editing the original Estimate and ADDING lines to the bottom indicating the cost codes and dollar amounts that are causing the increase.
- Creating a Sub-Job of the Job called Change Order 1 (2, 3, 4, ect.) and creating an estimate at the Sub-Job level to track just the cost codes involved in the change order.
Dealing with Negative Change Orders that reduce the original bid amount, is a bit more difficult – because QuickBooks will not allow you to create a Negative Invoice.
When you receive a negative change order that is LESS than the remaining balance on the contract, it’s a fairly easy process.
- Go to your QuickBooks Estimate, add a Change Order Item with no dollar amount – this provides a clear separation of the Original Contract amount.
- Below that add the Item that represents the reduction to the contract, enter the value as a negative amount, complete with the MINUS sign.
When you are ready to prepare your next progress invoice:
- Bill the negative amount at 100%.
- Reduce the corresponding line item in the original contract section.
- Bill for any other line items that you need to.
Or simply generate a zero dollar invoice to record the reduction.
This method allows for a good documentation trail that everyone involved can easily see.
Retention or retainage is usually a specific percentage, for example 10%, of the total contract that is held back by the project owner in reserve to protect the owners interest. Retention is not held in a lump sum, but rather held at the stated percentage for the amount requested on each application for payment. Your contract should set the terms, including the percentage and when the hold-back will be paid.
Contractors using QuickBooks often run into difficulties when handling retainage/retention; simply because the software doesn’t have a means to automatically deal with it.
Because QuickBooks doesn’t have a built-in retention function, like many of the more expensive construction specific software program, QuickBooks users must initiate work-arounds and make QuickBooks track retainage that is held on each progress invoice.
Over the years, I’ve seen several work arounds that various contractors, their bookkeepers, and even their accountants have implemented, such as:
- Simply leaving the retention amount of each invoice sitting in their open A/R.
- Billing for just the amounts on each line item that they will be paid for.
- Creating a Customer called Retentions Receivable and then making some fancy Journal Entries each billing period to move the retainage from the originating customer to the Retentions Receivable customer.
- Using a QuickBooks Discount Item to deduct retainage on individual invoices and mapping it to the Chart of Accounts as either an Income Account or Expense Account.
- Creating an Other Current Asset Account, called Retainage (Retention) Receivable and through the use of “Items” automatically move the money to this account on each invoice that is generated.
- Creating a Sub-Account of Accounts Receivable called Retainage (Retention) Receivable and then through the use of Items and additional invoices move the retainage amounts into this newly created Accounts Receivable sub-account.
Each of these methods has their own drawbacks, however, the first three (4) methods described cause the most problems with the contractors accounting records and are methods that I highly recommend that you avoid.
The easiest method that I know of, is tracking Retainage as an Other Current Asset Account on your Chart of Accounts – Balance Sheet section; however, MUST get with your accountant and have him teach you to do a journal entry that will remove the amount from Income.
To implement this system:
- Add an Other Current Asset account to your Chart of Accounts called Retainage or Retention Receivable.
- Create an Other Charge OR Service item in your Item List called “Less Retainage”, map this to the account you created in Step 1, and in the Rate box enter -10.0%.

- Create another Other Charge or Service item in your Item List called “Retainage Due”, again mapping it to the account you created in Step 1.
- Make sure that you have a Subtotal item in your Item List.
- Create your Invoice or Progress Invoice billing for the full amount before any retainage is withheld. On the first blank line at the bottom of the Invoice, select your Subtotal item and then your Less Retainage item – the balance on the invoice that goes to A/R is now the amount after retainage, and the retainage dollars are moved to the Other Current Asset Account.

- You can generate Reports on the Retainage Receivable account showing who owes you what by going to your Chart of Accounts, click on the account created in Step 1 to highlight it, click the Report button at the bottom of the window and choosing QuickReport .
- When you are ready to bill for retainage, create a “normal or regular” invoice using the Retainage Due item and entering the appropriate dollar amount from the report.
As I stated earlier in this article, this is the easiest method – because it’s just adding two additional items to the bottom of your invoice and all the math and work is done for you; however, the amount of retainage that you deducted shows up in your Profit & Loss Report in your Income Account (even if you run the reports on a Cash Basis) which does require that a Journal Entry be created to remove this from your Income. You should consult your accountant for the proper entry.
