Often recurring actions in retail regarding customer service (e.g. a phone call to invite a customer to collect a delivery) can be automated by SMS. This can save you a lot of time.
Text messages for retail marketing
You can also use Smstools for sending promotional texts (eg. "Hello ..., this weekend there's 20% off women's coats."), but also in text accompanied by a link that opens a mobile coupon in the receiving smartphone. This is a service we offer in collaboration with our online tool Coupontools.
Manage multiple locations
You can create sub-accounts for your different retail locations. You can centralise invoicing and SMS purchases while keeping control over all locations by consulting statistics.
