MI INNOVATIONS LLC operates Tendwa, shop-management software used by independent tire shops and automotive repair businesses. Text messages are sent by a repair shop to its own customers, using Tendwa as the software platform. Every message identifies both the shop and Tendwa.
Automotive customers do not create Tendwa accounts and do not complete an online sign-up form. They come to a repair shop in person or by telephone. Consent is therefore collected by the shop, in conversation, and recorded in Tendwa by the employee who collected it.
Providing a mobile phone number alone never constitutes consent. Consent is never assumed, never pre-selected, and always requires a deliberate action.
There are two approved methods. SMS reply confirmation is the recommended method.
Method 1 — SMS reply confirmation (recommended, double opt-in)
The customer confirms enrolment by texting YES from the handset being consented for. This is the strongest evidence available: it proves the number is reachable, that it belongs to the person agreeing, and that they acted deliberately.
- Customer provides a mobile number. The customer gives their mobile telephone number directly to the repair shop, by telephone or in person.
- Employee asks permission to send one message. The employee reads the preliminary permission script aloud. This asks only for permission to send a single enrollment message — it is not consent to service messaging.
- Employee records that permission in Tendwa. The confirmation control is unchecked by default and cannot be selected without a valid mobile number. Tendwa stores the employee's identity, the UTC timestamp, whether permission was given in person or by telephone, the number, and the disclosure version.
- Tendwa sends one enrollment message. Exactly one. It names the shop and Tendwa, states the message types, frequency and rates, and offers all three keywords.
- Customer replies YES. Only the customer can take this step. YES is matched as a whole message, so a sentence containing the word is never treated as consent.
- Tendwa records consent and confirms. Consent is recorded against that exact number with the UTC timestamp, the keyword, and the reply-consent version. One subscription confirmation is sent, and service-related messaging begins.
The permission script
Read aloud by the employee before anything is sent. It asks permission for a single message — it is not consent to service messaging, which only the customer’s reply can give.
“May we send you one text message so you can confirm enrollment in service-related SMS updates from [Shop Name] powered by Tendwa?”
Disclosure version:
SMS-ENROLLMENT-REQUEST-V1
The enrollment message
The one message Tendwa may send before consent exists, sent once:
“[Shop Name] powered by Tendwa would like to send you service-related SMS updates, including appointments, estimates, repair status, invoices, payments, and customer support. Msg frequency varies. Msg & data rates may apply. Reply YES to subscribe, HELP for help, or STOP to decline.”
The subscription confirmation
Sent once, immediately after a valid YES, recorded under version SMS-REPLY-CONSENT-V1:
“[Shop Name] powered by Tendwa: You are subscribed to service-related SMS updates. Msg frequency varies. Msg & data rates may apply. Reply HELP for help or STOP to unsubscribe.”
No service message is sent before the customer replies YES. If the customer never replies, no service messages are ever sent. An unanswered enrollment request expires after 7 days, and at most 2 enrollment messages are ever sent to a number. A customer who has opted out is not sent enrollment invitations at all.
Method 2 — Recorded verbal consent
The customer agrees aloud, and the shop records that agreement. Still offered and still valid, but the evidence is the shop’s own record rather than the customer’s own message.
- Customer provides a mobile number. The customer gives their mobile telephone number directly to the repair shop, by telephone or in person.
- Employee reads the approved disclosure. Before any messaging is enabled, the shop employee reads the approved verbal consent script to the customer, word for word.
- Customer gives affirmative consent. The customer must clearly agree. Silence, or simply having given a phone number, is not consent.
- Shop records the consent in Tendwa. On an unchecked-by-default control, the employee confirms the script was read and selects how consent was obtained. Only then may service-related messages be sent.
- Customer may reply STOP or HELP. The customer can opt out at any time by replying STOP, or reply HELP for assistance.
The approved verbal script
This is the exact disclosure the employee reads to the customer, where [Shop Name] is the name of the repair shop servicing the vehicle:
“Would you like to receive recurring service-related text messages from [Shop Name] powered by Tendwa? These messages may include appointment reminders, estimate updates, vehicle repair-status updates, invoices, payment confirmations, and customer-support messages. Message frequency varies. Message and data rates may apply. You may reply STOP at any time to unsubscribe or HELP for assistance.”
Disclosure version:
SMS-VERBAL-CONSENT-V1
The employee must receive a clear affirmative response before enabling SMS messaging. Silence, failure to object, or merely providing a phone number does not constitute consent.
The methods an employee may select when recording verbal consent are limited to verbal — in person and verbal — by telephone. Web form, paper form and QR code are not offered, because none of those methods is used.
How consent is recorded in Tendwa
The following screenshots show the employee workflow used to record a customer’s verbal SMS consent in Tendwa (Method 2). The examples use fictional demonstration data and contain no real customer information.

What consent covers
Consent is recorded against a specific mobile number and is verified centrally before every outbound message. It is not transferable. If a customer changes their mobile number, consent does not move with them: the new number requires new consent, and any pending enrollment request for the old number is cancelled. The original record is retained.
Consent is optional and is never a condition of any repair, purchase, or service.
Consent data retained
When a shop records consent, Tendwa may retain:
- A reference to the customer or authorized contact.
- The mobile phone number the consent covers.
- Consent status.
- Consent method — SMS reply confirmation, verbal in person, or verbal by telephone.
- The date and time consent was given, in UTC.
- The employee who collected the permission or recorded the consent.
- The version of the approved disclosure that was read.
- On the reply path, the confirmation keyword the customer sent.
- Revocation and opt-out status, including when a customer replies STOP.
Message types
Customers who consent may receive service-related messages such as:
- Appointment confirmations and reminders
- Estimate availability notifications
- Estimate approval requests
- Vehicle repair-status updates
- Vehicle-ready notifications
- Invoice and receipt notifications
- Payment confirmations
- Customer-support responses
- Service-related follow-up messages
These are transactional and customer-care communications relating to work on the customer’s vehicle. Tendwa does not send marketing or promotional messages on this campaign.
Stopping messages
Reply STOP at any time to unsubscribe. STOPALL, UNSUBSCRIBE, CANCEL, END, QUIT also work. Messages stop immediately and consent is recorded as withdrawn. The consent history is retained as a record of what was agreed and when.
Reply HELP or INFO at any time for assistance, or contact the repair shop directly.
START and UNSTOP are carrier resubscribe keywords. They clear a carrier-level block but do not restore consent in Tendwa: to resume messages, confirm enrolment with the shop again. Customers may also ask the repair shop directly to stop messaging them, and the shop can record that withdrawal on the customer’s behalf.
Message frequency varies based on appointments, estimates, repair activity, and customer-support interactions. Message and data rates may apply. Wireless carriers are not responsible for delayed or undelivered messages.
Privacy and legal
Mobile phone numbers and SMS consent records are not sold or shared with third parties or affiliates for their marketing or promotional purposes.
Service providers may process information only as necessary to operate and deliver the messaging service.

Primary call-to-action evidence on this page:
- The verbatim enrollment message a customer receives, and the YESreply that grants consent — the customer’s own message, from the number being consented for.
- The published verbal consent script, shown above in full.
- A screenshot showing the consent confirmation unchecked by default.
- A screenshot showing how consent is recorded after the customer gives affirmative agreement.
No public customer SMS signup form is used. Customers do not create Tendwa accounts. The repair shop obtains consent directly from the customer, by one of the two methods above, and records it in Tendwa.
