Available Assignments:

Applications: When you log in to MSL Online, you will see a range of assignments available for you to apply for. Payment details and reimbursement amounts will be clearly displayed so you can make an informed decision about which to pursue.

If you decide to apply for an assignment and agree with the advertised payment, simply click the apply button. Payment for services will be agreed before application acceptance.

After applying for an assignment, please check your MSL Online inbox to see if the assignment is there. This means your application has been successful. Please do not start any assignments until you can see them in your inbox. If your application is unsuccessful, we may not be able to notify you.

You have complete freedom to either accept or reject any assignment. If you change your mind about completing an assignment, please let us know by using the “decline” button on MSL Online or contacting us via phone or email.

While we do our best to offer assignments, sometimes we may need to cancel them at short notice. We will contact you as soon as we can (at the latest, 11am the day of the assignment unless stated otherwise in the shopper brief).

Shopper Brief: For each assignment, we provide a Shopper Brief, Assignment Information and other instructions. These are based on what our client has agreed to pay us for, so it is important to follow them closely. As long as the brief and any other instructions you are given are complied with, the precise way in which you undertake an assignment is up to you. We won’t be able to pay fees/reimbursements if the brief has not been complied with. If you’re unsure about any instructions, please contact us before conducting the assignment.

Please keep all notes, copies of reports, recordings and other documentation secure for 60 days after completing the assignment.

Substitutions: We understand that there may be times when you’re unable to complete an assignment. In such cases, you may use a substitute worker who has the appropriate profile, skills, security access if applicable and briefing. Please let us know if you plan to use a substitute worker for the first instance of each different type of assignment. Please note that you remain responsible for the satisfactory completion of the assignment and reimbursing the substitute.

Completion Dates: Completion dates (deadlines) are set by the client, and it is essential to deliver within the specified timeframes. Please help us by adhering to these completion dates, so we can ensure client satisfaction and payment. Late submissions may result in non-payment.

Unique Assessments: Please complete one assessment form per assignment, making sure that the interactions reported on are unique and not duplicated. If multiple people complete assignments for the same target organisation (e.g., family and friends), they must do so at different times/days to ensure each interaction is unique.

Fee And Expenses:

We will communicate all the information you need about fees and expenses for your assignments on MSL Online. We value our relationship with you and are committed to ensuring you are paid as quickly as possible. If you have any concerns, please do not hesitate to discuss them with us at the earliest opportunity.

Payments will be processed within 28 days of successfully completing your assignment in line with the shopper brief and other instructions. You can choose how you receive payment – either through BACS or PayPal. Please make sure to complete the Payment section of your profile before starting an assignment. If you select PayPal, there will be a small transaction fee (2.9% + 30p), so if you prefer not to pay this, just select BACS instead.

If you have any expenses that need reimbursing in line with the shopper briefing materials, please let us know when you complete your assessment or expense claim form and include the receipt/invoice. 

But please remember, we can only accept claims up to 60 days after you submit your completed assessment.

Please ensure you only return or exchange goods if it is specified in the Shopper Brief.

Sometimes we may need to clarify some details with you, which could cause a delay in processing payments. Please respond to any communication from us as quickly as possible (failure to do so may result in non-payment). If you need clarification on anything, do not hesitate to reach out to your MSL contact or decline the assignment. Please kindly note it is your responsibility to ensure your contact information is accurate.

Self-Employed Mystery Shopper and Liability:

As a self-employed independent contractor you are entirely free to provide your services to any other business/organisation.

You will be responsible for your Tax and National Insurance liability in respect of any payment received for services provided under this agreement. We trust that you will keep this in mind when calculating your income.

When handling/carrying/processing products/goods from a client for an assignment, we trust that you will handle the products with care. Please be aware that you will be liable for any damage due to negligence.

As a self-employed individual, you conduct assignments at your risk, and we are not liable for any personal injury or loss sustained. With this in mind, we advise you to take out any relevant insurance, such as public liability insurance. However, we trust that you will use your best judgment while completing assignments. If you have any concerns about any aspect of an assignment, please contact us, or decline the assignment, or both.

We believe that our mystery shoppers are honest individuals and trust you will not engage in any fraudulent activities. Sometimes people are not aware of what constitutes fraud in mystery shopping, so for the avoidance of doubt, please see a few instances below:

® Deliberate falsification of assessment forms, attachments or materials supplied
® Using a third-party identity whilst creating a shopper account
® Registering multiple accounts

In the hopefully unlikely event a shopper is suspected of fraudulent activity, their account will be suspended until further notice and any payments due will be withheld. Furthermore, the shopper would be liable for any damages, including loss of business, that may arise. Their details may be disclosed to the client for the purpose of investigating allegations. As you can imagine, we must take fraud cases extremely seriously and we will report all instances to the relevant authorities.


It is important that our assignments remain a mystery, so we trust that you will keep all the details of your assignments and experiences completely confidential. Please only disclose the information to close family and friends on a need-to-know basis.

It is essential to note that you must never contact the target organisation in reference to your assignment under any circumstances. Please contact us in the first instance should any issues arise.

To ensure unbiased results and maintain confidentiality, please do not accept any assignment if you are personally (or becoming) an employee, shareholder or contractor of the target organisation or know someone who works there. If you come across someone you know during the assignment, please contact us for guidance. If you cannot reach us, please avoid assessing that person wherever possible and email us with the details following the assignment.

We ask that after 90 days, you destroy all notes, copies of reports, recordings, and other documentation by shredding, tearing, or deleting from electronic devices. This is to maintain the confidentiality of employee information.

We may use your email address or phone number to send you updates, including assignment availability or an email newsletter. We may also occasionally use your address information for location-specific assignments, but we promise never to sell, rent, lend or distribute your personally identifiable information collected online.

The company will collect and process information relating to you in accordance with the privacy notice which is on our website and on the mystery shopper online portal.

We trust that you will protect your account by keeping it secure and not disclosing your username or password to any third party.


You can remove yourself from our active database at any time by using the links provided in the footer of email communications or by logging into your online shopper portal and deactivating your account. Just remember that you must still adhere to the relevant sections of this contract for 90 days after deactivation.

If you would like to request the erasure of your personal information from our system, please contact our Data Protection Manager via email at Your privacy is important to us, and we will process your request promptly.

We reserve the right to terminate this agreement with immediate effect at any time and for any reason, including in the event of any suspected fraudulent activity.

We reserve the right to modify, alter or update this contract at any time. However, we will always notify you of any changes.
