Sinclair Customer Metrics (SCM) is a legitimate mystery shopping company which I have conducted many mystery shops for over the past few months. I have been promptly paid for my efforts and the shop forms are easy to complete.
Sinclair Customer Metrics is not a huge company, like Marketforce, but they contract with a range of companies for which they have available shops. In my area they have shops ranging from banks to retail stores to quick serve restaurants. The company usually pays reimbursement up to a certain amount for your purchase and will give you a shop fee on top of that. If they are having a hard time getting a shop completed, for example a location in an airport, then they will offer a bonus on top of the regular fee. I completed a shop for them at an airport (past security) when I went on vacation a few months ago and got paid $20 + reimbursement because I got a bonus! Pretty sweet for only 10 minutes of work.
Sinclair Customer Metrics uses an online shop assignment system which is easy to use and will email you when they add new shops in your area. Their online shop reporting form is simple and uses a mix of free-form text boxes and bubbles to select. Additionally, receipts can be uploaded into the web reporting form. Sinclair requires their shoppers to complete online tutorials prior for each company they provide shops for. The tutorials are easy to understand and give the specific guidelines for the shop. Some shops are more complicated than others and the shop fee will usually reflect the level of difficulty.
Sinclair Customer Metrics pays by check each month for the previous month. There is no need to request a payment as the company automatically sends you the check. I have had an enjoyable time conducting shops for this company and urge you to sign up also!
