Lockhart

Every enquiry answered, even when you can’t.

An automated assistant on your WhatsApp, and a voice agent for the calls you miss. It takes the details and sends you a summary within a minute.

  1. 21:47A customer messages your WhatsApp after hours
  2. 21:47The assistant says it’s automated and takes the details
  3. 21:48You get the summary, with urgent ones flagged
From the example conversation below

Not installed for clients yet: Lockhart runs its own assistant first, so the costs and answers are proven before you pay for one.

What it does with every message.

  1. Answers in seconds

    On your WhatsApp number, day and night, from a short file of your services and prices that you approve.

  2. Says it’s automated

    Its first message makes clear it is an assistant. It never pretends to be you or a member of staff.

  3. Takes the details

    Name, what they need, where, and when to call back. One question at a time, and only what it doesn’t already know.

  4. Hands the job to you

    A summary on your WhatsApp within a minute, with urgent enquiries flagged and the full transcript attached.

Add-on: payment reminders.

Polite reminders by WhatsApp and email on invoices that are overdue, on the schedule you set. It never changes an amount or a due date, and anyone who replies is handed to you.

An add-on to the WhatsApp Assistant, not included in its price. WhatsApp message fees are billed at cost. No VAT is added.

An enquiry at 21:47. A summary on your phone at 21:48.

While you’re off the clock, the WhatsApp Assistant answers, says plainly that it’s automated, takes the details one question at a time and hands the job to you.

Example conversation. The business and the names are made up.

Coastline Plumbing, automated assistant
  1. Customer: Hi, our geyser just burst. Can someone come out tomorrow?
  2. Assistant: Hi, you’ve reached Coastline Plumbing. I’m their automated assistant, and I’ll take your details for the team. What’s your name?
  3. Customer: Sipho Ndlovu
  4. Assistant: Thanks, Sipho. Which suburb are you in?
  5. Customer: Salt Rock. The water’s off at the mains.
  6. Assistant: Good. The team replaces geysers, including the compliance certificate. When would you like them to call you?
  7. Customer: Before 8 tomorrow if possible
  8. Assistant: I’ll save these details so the team can contact you. You can ask us to delete them at any time. I’ve asked them to call you before 08:00.

What it never does

  • Quotes beyond your price list
  • Gives a discount or commits you to a date
  • Gives legal, tax or financial advice
  • Invents an answer. If your file doesn’t cover it, it says so and takes a message

Your customers’ data.

Handled under POPIA. The privacy page sets out what is stored and where.

  • Every conversation states that it is automated. Every call states that it is recorded.
  • Before saving details it says so: “I’ll save these details so the team can contact you. You can ask us to delete them at any time.”
  • A request to delete details is logged and flagged to you to action.
  • Conversations are never used to train AI models.
  • Replies are written with Anthropic’s Claude. Messages travel through WhatsApp (Meta), and conversation records are stored with Supabase.
  • It replies only from your approved file and never quotes beyond your price list. It never creates a quote or an invoice; with the payment-reminders add-on, reminders only follow up invoices you have already sent.

Two assistants, fixed prices.

A one-off set-up fee, then month to month. No VAT is added.

Assistant questions

Question not here? WhatsApp Luke and he’ll answer it himself.

Can it use my existing WhatsApp number?

It needs a number on WhatsApp’s business platform, and a number on that platform cannot also be used in the normal WhatsApp app on a phone. Most businesses give the assistant a new number, or move their main number and reply from a dashboard. Luke will set out the options for your business.

What if it gets something wrong?

It answers only from a short file you approve. If the file doesn’t cover a question, it says so and takes a message. You can read every transcript, and the file is updated as you go.

What does it cost to run?

The monthly fee covers the assistant. Meta, which runs WhatsApp, also charges a few cents for each message: about R0.12 for a reply to a customer.

Meta’s fees are billed at cost, with nothing added. You agree a monthly cap at set-up, and Lockhart alerts you before your fees reach it.

Whose name is the WhatsApp number in?

Yours. The WhatsApp number and the Meta business account are registered in your business’s name, so they stay with you if you stop the service.

How long does it take to set up?

The WhatsApp Assistant goes live in 2 weeks. With the Missed-call Voice Agent it takes 3 to 4 weeks.

Can I stop it if something goes wrong?

Yes. Reply in the chat yourself and it stands down on that conversation for 24 hours.

Does it book appointments?

It books calls. Booking into a calendar is planned as an add-on once the core assistant has run for a month.

See what yours would say.

Send Luke your website address on WhatsApp. He’ll show you what your assistant would know, and what it would hand over to you.
