Frequently Asked Questions
What is the Sovereign Plus App?
Who can use the Sovereign Plus App?
The app is available to all subcontractors who are paid through Sovereign Plus. Once you’ve been invited to register, simply download the app and complete your account setup to get started.
Is the Sovereign Plus App free to download and use?
Which devices is the app available on?
The Sovereign Plus App is available to download on both Apple and Android devices via the App Store and Google Play.
I've got a problem with the app. How do I get help?
Our friendly team is always happy to help. If you’re having any issues with the app or can’t find what you’re looking for, simply get in touch and we’ll get you back up and running as quickly as possible.
How do I register for the Sovereign Plus App?
How do I access my payslips?
Your payslips are available within the app as soon as the timesheet is submitted. Simply log in and head to the Timesheets section, where you can view or download both current and previous payslips whenever you need them. They are also emailed to you.
Can I view and download my CIS statements?
Yes. Your monthly and annual CIS statements are available within the app and can be viewed or downloaded whenever you need them. They are also emailed to you.
Will I receive notification about my payment?
Yes. Once your timesheet has been submitted, we’ll send you a text message confirming exactly how much will be paid into your bank account after deductions. Unless your contractor operates a different payment schedule, you can expect to receive your payment between midnight and 6:00am every Friday.
Can I update my personal details?
Yes. You can request changes to your personal details, including your bank details, directly through the app. Any updates are reviewed by our team before they’re approved, helping to keep your information accurate and secure.
Is my personal information secure?
Absolutely. Protecting your personal information is a top priority. The Sovereign Plus App uses secure technology to keep your personal, payment and compliance information safe.
What should I do if I think my payment or deductions are incorrect?
If your payment doesn’t look quite right, don’t worry—we’re here to help. Start by checking your payslip in the app, where you’ll find a breakdown of your payment and any deductions. If you still have a query, speak to your contractor first, as they approve and submit your timesheet. If the issue remains, simply get in touch with our team and we’ll be happy to investigate.
Can I see my hours worked in the app?
The app displays your payment information, including a breakdown of any deductions, but not your approved hours. If you’d like to confirm the number of hours submitted, simply give our team a call.
How can I contact Sovereign Plus if I need help?
We’re always happy to help. You can contact the Sovereign Plus team in whichever way is most convenient for you:
- Chat with us directly through the app (available during office hours).
- Call our office or your dedicated contact.
- Email us and we’ll get back to you as soon as possible.
Our team is here to answer any questions and help resolve any issues as quickly as possible.
