Honesty & Integrity: All our work and all our relationships are based on this foundation of trust.

Caring Customer Service: We sincerely care about our clients, going above and beyond to serve. All of our staff members constantly look for the best way to help you.

Customization: Each client does payroll slightly differently. We respect the way you work, so we customize our strategy and tools to fit your needs.

Long-Term Relationships: Our customers know we’re all on the same team. You can work with the same people, year after year, and we go out of our way to be there for you.

Accessibility: Our phone is answered by a friendly human during business hours. We make cell phone numbers available, just in case. Senior management is available to speak to customers whenever needed. We are here to be of service.

Educating Customers: We educate customers to make the best decisions. If you ask us a question, we will give you the best options available, based on decades of experience. We also offer training programs right in our office.

Accuracy: All our work will be correct to the best of our knowledge. We pay careful attention to detail, and keep constant watch on the latest standards and requirements.

Timeliness: We turn things around quickly, so you can meet every single deadline.

Happy Employees: You can work with a well-educated, experienced team year after year, because we invest in our staff. We’ve created a great place to work and provide ongoing education to develop each team member.

Good Stewardship: Your data and funds are safe with us. We don’t place client funds at risk. Period. All your funds can be reconciled and accounted for at any time. In addition to high standards of electronic information protection, we take special care of your information by controlling paper documents in our building. And we continue to educate our staff about possible security threats.

How is Southwestern Payroll different than a typical payroll service?

Like a typical payroll service, Southwestern Payroll smooths the bumps in the road (and in some cases, removes the hazards), but rather than take over the wheel, Southwestern Payroll puts you in the driver’s seat.

Specifically, Southwestern Payroll is a combination of software and services, available for one flat-fee. It’s a native, internet payroll solution designed to provide you full on-demand access to all payroll and HR functions within one system, without the added headaches of making tax deposits and filing quarterly and annual reports.

Southwestern Payroll also provides an HR Support Center, which includes live answers to your HR questions, a comprehensive library of HR forms and common job descriptions, educational articles and newsletters, and many other HR resources at your fingertips.

With key statistical HR and payroll data (HR Dashboard), a custom report writer with access to real-time data, and an employee self-service portal, all available 24×7 within a single secure system, Southwestern Payroll is much, much more than a typical payroll service.

Can I offer my employees direct deposit of their paychecks?

Yes, direct deposit is included in our service at no extra charge. Employees can deposit into an unlimited number of accounts.

What hardware or software do I need?

No special software, nothing to load. All you need is a broadband connection to the Internet and a web browser.

Will Southwestern Payroll interface with my accounting system?

Southwestern Payroll interfaces with most popular accounting systems. After you set up your chart of accounts, you simply download a file to import into your accounting program. It’s much easier than you might think.

How do I know my taxes are being paid?

We guarantee that your taxes will be calculated and deposited correctly and on time. Your tax deposits are all fully bonded and insured.

What reports do you have and how do I get them?

Southwestern Payroll provides many standard pre-built reports available at any time for any current or past payroll. We also provide a custom report writer for your ad hoc reporting needs.

Do employees have access to their data?

At your discretion, you can set up your employees to log into the employee self-service portal of Southwestern Payroll. They can view past paychecks, update contact information and review paid time off balances. This service is provided at no extra charge for you or your employees.

What do I need to get started?

We need your authorization to pay taxes on your behalf, collect funds to pay for our service and the balance information on your employees. To receive our electronic startup packet, contact us.

Is my information secure?

Southwestern Payroll utilizes the most advanced security protocols available. We utilize 128-bit secure socket layer security and treat your confidential data with the highest respect. We don’t like people selling our information; we won’t sell yours. Read our privacy policy.

Can I track employee events such as review dates and expiration dates?

Yes, you can customize your Southwestern Payroll Dashboard to display upcoming events such as annual review dates, motor vehicle report due dates or employee birthdays. You can also generate date-sensitive reports for any employee events.

What’s the HR part of Southwestern Payroll all about?

Southwestern Payroll is more than just a traditional payroll service or software. It is an on-demand HR system that generates your payroll and tracks employee events, turnover, review dates, company property and employee training. Additionally, you have access to HR answers and resources in the HR Support Center.

Can I allocate employees’ pay to different departments?

Yes, you can allocate employee pay to different departments, work sites, divisions and even project numbers.

When are reports available to me?

With Southwestern Payroll, reports are available immediately which is when you want them. As soon as you key in payroll time, you can review any payroll report, so you can verify the data is correct before printing the checks.

Can I track my employees’ vacation, sick and other paid time off?

Yes, you can set up each employee to accrue time per pay period, month or year. You can also set up time that will roll over to subsequent years.
