Who calls when you're closed
In the evening, at weekends and on public holidays, people call you for four reasons: to book an appointment, to ask a practical question, to change something already under way, or to report an emergency. The first three can be dealt with completely, at any hour, by an AI voice agent. The fourth needs a rule written in advance: who receives the call, at what times, and what happens if nobody answers.
- People who can only call after work. They want an appointment or a quote. Voicemail promises them a callback tomorrow, during their own working hours: the conversation often never happens.
- Practical questions. Tomorrow's opening hours, address, directions, documents to bring, the area you cover.
- Existing customers. Moving an appointment, adding details to an order, letting you know they're running late.
- Emergencies, real or perceived, that won't wait until you open.
This guide covers the ordinary rhythm of the week. For a closure of several days, holidays or an annual shutdown, the guide to holidays and closures sets out the preparation specific to those periods.
What the agent can do out of hours
Booking and moving appointments
The agent reads your calendar in real time, in Google Calendar, Microsoft 365 or Cal.com, offers slots that follow your rules, books, then confirms by SMS. It can also move or cancel an existing appointment. Someone who calls at 9 pm hangs up with an appointment, not a promise of a callback.
Giving information
Opening hours, address, parking, documents to bring, the prices you have set, the area covered: the agent answers with your information, and only with that. If you have prepared SMS (the address, directions, a link), it sends the right one during the call, with the caller's consent.
Taking a qualified message
When the request can't be dealt with straight away, the agent gathers what is needed for a useful callback: name, number, reason for calling, level of urgency, when the caller can be reached. The summary arrives by email with the transcript, and you read it the next morning, not at midnight.
Emergency transfer rules
Out of hours, a transfer is the exception. If it becomes the rule, the person on call never sleeps and ends up not answering. Write down three things.
- What is urgent. A short list, specific to your trade, with the questions that help recognise it. The guide to urgent calls for tradespeople helps you write it.
- Who receives the call, and when. With Sayelo, each transfer number can be offered only at certain times: the evening on-call, the weekend on-call. From the Pro plan, several transfer numbers can be set up according to the reason for calling. Transfers go to landlines and mobiles in the 9 countries where Sayelo is open.
- What happens if nobody answers. The transfer is direct, with no announcement: if nobody picks up, the caller reaches the on-call number's voicemail. Have the agent give the safety instruction or the planned referral before transferring, and record a greeting on that line saying what to do while waiting for the callback.
| Situation | What the agent does out of hours |
|---|---|
| Life-threatening emergency, warning signs | Immediate referral to the emergency services, never an appointment |
| An emergency in your trade | Transfer to the on-call person during their hours, otherwise a priority message and safety instruction |
| Serious problem that can wait until the next day | First available slot, or a priority message |
| Routine request | Appointment, information or message |
Two trades where the night matters
A veterinary clinic asks the agent to recognise serious situations (poisoning, breathing difficulties, seizures) and transfer them immediately to the on-duty vet. The agent passes on the species, weight and symptoms before putting the call through, to save time. Everything else becomes an appointment or a message. Our veterinary practices page details these rules.
A locksmith gets calls at night from people who are locked out. The agent alerts the on-call locksmith, states the call-out charge and the night surcharge as you have set them up, and refers the caller to the emergency services if a vulnerable person is locked in or in danger. Requests for a security door upgrade wait until Monday. The locksmiths page shows a typical call.
The special case of public holidays
A public holiday often falls on a weekday, and that's where settings go wrong. If your transfer time slots follow the days of the week, a bank holiday Monday looks to them like an ordinary Monday: your daytime mobile will ring while you're with your family and, if you have several transfer numbers, the weekend on-call line will stay silent. Get into the habit of checking three things the day before each public holiday: the agent knows you're closed that day, the right on-call number is offered, and the calendar has no slot left open by mistake. The day after, put your usual settings back.
What the agent doesn't do, even at midnight
- It doesn't hide that it's an AI. It says so in its very first sentence.
- It gives no medical, veterinary or technical advice. No diagnosis, no dosage, no repair advice beyond the safety instruction you have written.
- It doesn't make up prices or timescales. It repeats the amounts you have given it, and doesn't promise an arrival time that nobody has approved.
- It takes no payment over the phone.
- It doesn't replace the person on call. If nobody is on call, it says so and points the caller to the right alternative, rather than letting them believe someone is coming.
The next morning
When you open, the previous evening's calls are already sorted. Booked appointments need no action: they're in the calendar and confirmed. Calls that need follow-up end up in “Activity” → “Calls”, with the “To do” filter, until someone deals with them. Start by checking that the transferred emergencies were dealt with, then call back the priority messages, then the rest. The guide to calling a customer back after a call explains how to read the summary and prepare each callback.
Night answering service or voice agent
With a human call answering service, evenings, Saturdays and public holidays are usually extras billed on top, when they are offered at all, and the operators pass on a message that still has to be dealt with. The comparison between an AI voice agent and a call answering service details these differences. With Sayelo, the answer is the same at any hour, with no night or weekend surcharge, and the plans are set out on the pricing page.
The agent replaces neither you nor your on-call staff: it keeps the line open while the team rests, and wakes the right person only when it has to.
