I, too, am very pleased with how our entire organization has faced and overcome the many challenges of 2020. Our teams have our deepest appreciation for the excellent job they're doing to fulfill customer orders at a time of unprecedented demand for our products.
Throughout this year, we've maintained a range of measures to ensure financial flexibility, including eliminating discretionary expenses, implementing a hiring freeze for most open positions and focusing capital spending on critical projects. We have demonstrated effective working capital management and expect to continue to increase cash flow and reduce debt. We remain disciplined, yet opportunistic in our expense and capital investment approach, focusing on maintaining a strong balance sheet to ensure we have the necessary flexibility as we navigate these uncertain times.
Now let me review our third quarter 2020 results from continuing operations compared to the third quarter of 2019 and discuss our outlook.
Total revenue decreased 26%. The main reason for the decline was lower sales volume in the U.S. consumer market, which occurred as a result of greater-than-expected challenges implementing our new ERP system. While unprecedented demand continued, the cutover to the new system temporarily reduced shipping capabilities at our U.S. distribution center. Additionally, constraints in the transportation industry also adversely affected shipping capabilities.
The shipping hurdles related to ERP are resolved and behind us, and operations at our U.S. distribution center are operating effectively.
In the international consumer and global commercial markets, lower sales were expected and driven by pandemic-related demand softness. In the Canadian consumer market, sales volumes increased as we expected.
Our operating loss in the third quarter was $2.4 million compared to an operating profit of $4.4 million last year. Gross profit declined due to lower sales volume, however, gross profit margin increased 80 basis points from customer and product mix.
Selling, general and administrative expenses decreased $300,000. The decline is primarily due to lower overall spending and the benefit in the reduction to environmental reserve at 1 site. These benefits were partially offset by increases in employee-related costs due to increased incentive compensation, mostly driven by the increase in the market price of our stock, legal and other third-party fees primarily related to the irregularities in our Mexican subsidiaries and an increase in the contingent loss related to patent litigation. The 2019 third quarter includes a charge of $2.6 million to write off unrealizable assets of our Mexican subsidiaries.
Turning to the balance sheet. As a result of improvement in net working capital, we have had lower average borrowings outstanding under our revolving credit facility ending the quarter with net debt of $69.6 million as compared to $78.6 million in the prior year. This along with our average interest rate has resulted in decreased interest expense.
Use of cash before financing activities improved significantly compared to prior year, with the use of $8.8 million for the 9 months ended September 30, 2020, compared to use of $27.3 million for the 9 months ended September 30, 2019. Because of the seasonal nature of our business, we typically build inventory and accounts payable during the third quarter. The net impact to cash flows to the change in inventory and accounts payable is relatively consistent year-over-year. The increase in inventory is a result of a sales shortfall for the quarter.
With the expected shift of sales into the fourth quarter and strong demand expected to continue into 2021, we believe that our inventory position supports us well to meet our customers' demand.
Next, let me turn to our outlook. We continue to believe we are well positioned to effectively navigate the ongoing COVID-19 environment as demand remains elevated and our cost management measures remain in place. For the second half of 2020, we expect total revenue to be in line with the second half of 2019, and operating profit is expected to increase approximately 20%. Any interruptions in shipping caused by a further challenge transportation industry or unexpected ERP complications while not anticipated could cause results to fall short of expectations. The revenue outlook includes the impact of converting some order volume to direct import by customers to help ease strains on the shipping operations. Direct import sales -- with direct import sales, we recognized lower revenue as cost savings are shared with the customer.
If we imported the converted orders, revenue would be higher in the second half of 2020 by approximately 8 million, which will result in modest growth. Our goal continues to be to exceed $20 million in cash flow from financing activities for the full year. Timing of some accounts receivable collections could move into the first quarter of 2021 due to timing of revenue expected to shift from the third quarter of 2020 to the fourth quarter. We will know more as the fourth quarter unfolds.
Visibility into 2021 beyond the expectation of continuing strong demand in the first quarter is limited. So we're deferring any outlook for the full year 2021 to a later time. Also, looking ahead, Hamilton Beach Brands maintains a $115 million senior secured floating rate revolving credit facility that expires on June 30, 2021. As of the end of the quarter, we had not yet finalized the amendment to extend this facility. As a result, all amounts outstanding were classified as current liabilities at the end of the quarter. We're working very closely with our bank group and expect to finalize the amendment before the end of the month.
I'll note that there were no share repurchases during the third quarter. That concludes our prepared remarks. We'll now turn the line back to the operator for Q&A.
