1.Who we are

Next Clean is a web app that residential cleaning companies in the United States use to run their business: schedules, clients, estimates, invoices and payments. Next Clean is operated by Lynx Ledgers LLC, a Massachusetts limited liability company in Fall River, Massachusetts, USA.

Part of the app lets each cleaning company send service messages to its own clients by SMS, WhatsApp and email. This page covers SMS and WhatsApp.

2.Who sends and who receives

Sender: the cleaning company
For example, “Sparkle Home Cleaning”. It gets the client’s consent, decides which messages to send, and is named in them: the default text of every message ends with the company’s name, every WhatsApp template includes it, and replies typed in the chat start with it. Our Terms require companies to keep their name in every message.
Recipient: the client
The person who hired the cleaning company to clean their home, at the mobile number they gave the company.
Platform: Next Clean
Provides the software. SMS is delivered by Twilio from our toll-free number, +1 833-549-6398; for SMS, Next Clean is not the sender: the cleaning company is. On WhatsApp, messages come from the “Next Clean” business account: Next Clean sends them on behalf of, and with the authorization of, the cleaning company, which is named in every message. Either way, we do not choose who receives messages, and we never send our own marketing to clients.

5.Sample messages

These are all the kinds of messages a client can receive by SMS, with the app’s default English text, for a fictional company, “Sparkle Home Cleaning”, and a client named Maria. The same texts exist in Portuguese and Spanish, and each client receives them in their own language. A cleaning company can edit the wording, but it must remain a service message that names the company. Links are examples.

The first message

The first text message a cleaning company sends to a phone number through Next Clean ends with one more line, in the client’s language. In English: “Sent via Next Clean. Reply STOP to opt out, HELP for help.” The keywords STOP and HELP stay in English in every language. Later text messages from that company to that number do not repeat the line, but STOP works at any time.

Visit updates

  • Visit reminder (shown as a first message)

    The day before a visit, at 10:00 a.m., if the company turns this reminder on.

    Hi Maria! Just a reminder for your cleaning Wednesday, Oct 7. Sparkle Home Cleaning Sent via Next Clean. Reply STOP to opt out, HELP for help.

  • On the way

    When the team taps “On my way” in the team app, if the company turns this update on.

  • Cleaning completed

    When the team finishes the visit, if the company sends this update.

    Hi Maria! Your cleaning is completed. Thank you! Sparkle Home Cleaning

Estimates and agreements

  • Estimate

    When the company sends an estimate. The link opens a page where the client can approve or decline it.

    Hi Maria! Here is your estimate. https://app.nextcleanapp.com/s/Qe7Lm2x Sparkle Home Cleaning

  • Estimate follow-up

    Three days after an estimate is sent, at 10:00 a.m., only if the client has not answered and the company turns this on.

    Hi Maria! Just checking in: your estimate is still waiting for your answer. https://app.nextcleanapp.com/s/Qe7Lm2x Sparkle Home Cleaning

  • Service agreement

    When the company sends a service agreement to sign online.

    Hi Maria! Here is your agreement. https://app.nextcleanapp.com/s/Hk2Pw8r Sparkle Home Cleaning

  • Signed agreement

    Right after the client signs, with a copy for their records.

    Hi Maria! Here is your signed agreement. https://app.nextcleanapp.com/s/Hk2Pw8r Sparkle Home Cleaning

Invoices and payments

  • Invoice

    When the company sends an invoice, by hand, or automatically after a visit if the company sets this up. The link opens the invoice, where the client can pay.

    Hi Maria! Here is your invoice 1042. https://app.nextcleanapp.com/s/Tn4Vb6c Thank you! Sparkle Home Cleaning

  • Invoice payment reminder

    When the company sends a reminder, or three days after the invoice was sent, at 10:00 a.m., only if it is still unpaid and the company turns this on.

    Hi Maria! Friendly reminder: your invoice 1042 is still pending for payment. https://app.nextcleanapp.com/s/Tn4Vb6c Thank you! Sparkle Home Cleaning

  • Visit payment reminder

    When the company reminds the client about a visit that was not invoiced and is still unpaid.

    Hi Maria! Friendly reminder: your cleaning on Wednesday, Oct 7 is still pending for payment. Thank you! Sparkle Home Cleaning

  • Receipt

    When the company sends a receipt for a payment.

    Hi Maria! Here is your receipt. https://app.nextcleanapp.com/s/Rc9Jd3s Thank you! Sparkle Home Cleaning

  • Statement

    When the company sends the client a statement of their account.

    Hi Maria! Here is your statement. https://app.nextcleanapp.com/s/St5Gh1k Sparkle Home Cleaning

Feedback and conversation

  • Request to rate a visit

    After a visit, when the company asks for feedback. The link opens a short page to rate the visit from 1 to 5 and leave a comment.

    Hi Maria! Please review our cleaning on Wednesday, Oct 7. https://app.nextcleanapp.com/s/Rv8Ny2q Sparkle Home Cleaning

  • Reply in a conversation

    When someone at the company writes to the client in the chat, usually to answer a question or arrange a visit. By SMS it starts with the company’s name.

    Sparkle Home Cleaning: Hi Maria, we can come at 10 instead of 9 on Wednesday. Does that work for you?

  • Other service updates set up by the company

    A company can write its own automatic updates about the client’s visits and invoices, for example when a visit is rescheduled or canceled, or a thank-you after a payment. Example written by a company:

    Hi Maria! Your cleaning was moved to Thursday, Oct 8. Questions? Just reply here. Sparkle Home Cleaning

On WhatsApp

On WhatsApp, the same updates are sent as message templates that Meta must approve, in the same three languages. For example:

  • On the way (WhatsApp)

  • Invoice (WhatsApp)

  • Message from the company (WhatsApp)

Frequency and timing

Message frequency varies based on your service activity with the cleaning company. Automatic messages are limited to the visit, estimate and invoice updates above and to updates the company sets up about your own visits and invoices; everything else is sent by a person at the company. By default, the app holds automatic messages between 9:00 p.m. and 8:00 a.m. in the company’s time zone. Message and data rates may apply.

6.STOP and HELP

Stop text messages (SMS)

Reply with one of these words, on its own, to any text message:

  • STOP
  • STOPALL
  • UNSUBSCRIBE
  • CANCEL
  • END
  • QUIT
  • REVOKE
  • OPTOUT
  • SAIR
  • PARE
  • PARAR
  • BAJA
  • ALTO

Capital letters and punctuation don’t matter (“stop”, “Stop.” and “STOP!” all work), but the reply must be only the keyword: “stop by tomorrow” is read as a normal message. STOP, STOPALL, UNSUBSCRIBE, CANCEL, END, QUIT, REVOKE and OPTOUT are also the standard opt-out keywords that our SMS provider, Twilio, handles for our number. SAIR, PARE and PARAR (Portuguese) and BAJA and ALTO (Spanish) work in Next Clean too.

What happens when you reply STOP:

  • Next Clean immediately unchecks “Accepts SMS” on your record with the cleaning company you were last in touch with through this number, so that company sends you no more SMS.
  • Our SMS provider, Twilio, and the toll-free network also block all further SMS from +1 833-549-6398 to your phone, from any company using Next Clean, until you reply START or UNSTOP, and you receive an automatic confirmation.
  • Messages already waiting to go out are checked again before sending, so they are not sent.
  • The cleaning company sees that “Accepts SMS” was turned off.

Start text messages again

Reply START (or UNSTOP) to receive text messages again. This lifts the stop at our SMS provider, Twilio, and checks “Accepts SMS” again on your record with the company you were last in touch with through this number. Other replies, such as “yes”, do not turn text messages back on: they reach the company as a normal message.

Stop WhatsApp messages

On WhatsApp, reply with one of these words, on its own:

  • STOP
  • STOPALL
  • UNSUBSCRIBE
  • PARAR
  • PARE
  • BAJA

Next Clean unchecks “Accepts WhatsApp messages” on your record with the company you were last in touch with through this number. Reply START or UNSTOP to receive WhatsApp messages again. You can also block the business in WhatsApp at any time. (WhatsApp uses a shorter list on purpose: on WhatsApp, “cancel” almost always means “cancel my visit”.)

Help

Reply HELP (or INFO) to any text message for help. Our SMS provider, Twilio, sends an automatic reply. If you are a client of a cleaning company on Next Clean, your message also appears in your conversation with that company, so a person there can help with your service. For help with the messaging program itself, email [email protected].

Other ways to opt out

You can also tell the cleaning company in any reasonable way (by phone, in person or in writing); our Terms require it to uncheck the box. Or email [email protected] with your mobile number and the company’s name, and we will make sure your opt-out is applied.

7.Our commitments

  • Service messages only. The program sends messages about the client’s own cleaning service. Next Clean has no marketing or mass-texting feature for SMS or WhatsApp, and our Terms forbid using these channels for marketing or promotions.
  • Consent first. No SMS or WhatsApp message goes to a client unless the box for that channel is checked: by the cleaning company after the client agreed, or by the client’s own START reply. Consent to receive SMS is not a condition of purchasing any goods or services.
  • Frequency and cost. Message frequency varies. Message and data rates may apply.
  • Quiet hours. By default, automatic messages are not sent between 9:00 p.m. and 8:00 a.m. in the cleaning company’s time zone.
  • U.S. numbers. SMS is sent only to U.S. mobile numbers (+1), from a U.S. toll-free number. For any other number the app skips SMS and uses WhatsApp or email, if the client accepts them.
  • No SHAFT content. No content about sex, hate, alcohol, firearms or tobacco (SHAFT), cannabis or illegal drugs is allowed.
  • Opt-outs honored. STOP is applied by the app as soon as it arrives. Opt-outs made in other ways are applied as soon as we or the cleaning company receive them, and never later than 10 business days.
  • Mobile information stays private. No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. All other categories exclude text messaging originator opt-in data and consent; this information will not be shared with any third parties. We share mobile phone numbers only with the service providers that store and deliver messages for us: Supabase and Vercel (hosting), Twilio (SMS) and Meta (WhatsApp). Message text may also be processed by Anthropic when a business user asks the app to draft a reply, and by browser push services for business users’ notifications. None of them may use it for their own purposes or for marketing.
  • The company is named. Default texts name the cleaning company, and our Terms require companies to keep their name in every message.
  • Accountability. Each cleaning company keeps proof of its clients’ consent for at least four years and must give it on request. We can pause messaging for any company that breaks these rules.

8.Messages to business users

Separately from the client program, Next Clean sends account notifications to the people who run and work for a cleaning company (owners, office staff and cleaners). These never go to the company’s clients. Each one is sent only when the owner or an authorized user takes an action or turns on a setting:

Team invitation
When the owner invites a team member, by WhatsApp, SMS or email as the owner chooses. The link expires after 7 days. “Hi Ana! Sparkle Home Cleaning invited you to their cleaning team app. Set up your access here: [link]”
Pay stub
When the owner sends it, by SMS, WhatsApp or email. “Hi Ana! Your pay stub for the period is ready. [link] Sparkle Home Cleaning”
Client reply alert
A text to the owner when a client replies, while the owner keeps this setting on. “Sparkle Home Cleaning: Maria replied: …”
Team chat alert
A text to the owner when the team writes in a group chat, only if the owner turns it on.
Automation alert
A text or app notification to the owner from an automation the owner created.
Daily summary
A morning WhatsApp message and app notification to owners, only if the company turns it on.
Sign-in emails
Password resets and similar emails, from [email protected].
