Best time to cold call: how to plan B2B calling around when buyers answer

Nousu Collective logged 218,000+ dials into about 24,000 Australian companies between November 2024 and April 2026, targeting director, VP, C-suite and founder-level buyers. Across those dials, connect rates changed by a factor of four across the working day, from 22% at the 10am peak to 5% after 5pm.

68% of Nousu's qualified meetings come from calls placed in two windows: 10am to 11am and 2pm to 3pm. The full hour-by-hour table, including decision-maker conversation rates by hour, is in our post on the best time to cold call in Australia. This guide is about using that data to plan your calling.

The decision-maker conversation rate follows the same curve, which is the number that matters most. At the 10am peak, 11% of dials become a conversation with an actual decision maker; over lunch it is 4%, and after 5pm 2%. A dial in the peak is worth several dials at the wrong time.

The pattern makes sense once you picture a decision maker's day. The first hour is internal: email, stand-ups, the day's fires. By 10am the urgent things are handled and they are at their desk, which is why connect rates peak. Lunch empties desks and fills calendars with meetings. The early afternoon brings a second settled window, before the late afternoon fills with wrap-up and travel.

Wednesday is the most productive day in Nousu's data, narrowly ahead of Tuesday and Thursday. Monday morning is slow, because senior decision makers are often in internal meetings. Friday afternoon connect rates collapse so steeply that Nousu does not schedule calling then.

If you only have three days of calling a week, make them Tuesday, Wednesday and Thursday.

Public holidays shift the pattern. The day after a long weekend behaves like a Monday, with buyers catching up on internal work, and the day before often behaves like a Friday afternoon. State public holidays differ, so a national campaign may find Melbourne closed on a day Sydney is working. Check the state calendar for each market before you schedule a calling week, and move those dials to the next strong day rather than losing them.

Timing is also a compliance question. In Australia, the Telecommunications (Telemarketing and Research Calls) Industry Standard 2017 sets the hours when telemarketing calls may be made.

The hours apply in the time zone of the person you are calling, not yours. The best B2B windows sit well inside the permitted hours anyway, so this rarely costs you a good dial. In New Zealand and Singapore the rules differ: New Zealand's Unsolicited Electronic Messages Act 2007 covers email and texts rather than voice calls, and Singapore's PDPA Do Not Call rules exclude genuine business-to-business calls. This is general information, not legal advice. See our Australian compliance guide for detail.

The peaks are in the prospect's local time. A team in Sydney calling Perth at 10am Sydney time is calling at 7am or 8am in Perth, before the permitted hours and before anyone is at their desk.

Daylight saving is where national programs go wrong. Queensland, Western Australia and the Northern Territory do not use it, while New South Wales, Victoria, the ACT, Tasmania and South Australia do, from the first Sunday in October to the first Sunday in April. A calling plan that works in July is an hour out for Brisbane and Perth in November. Set your dialler and calendar to show the prospect's local time, rather than relying on anyone's mental arithmetic.

Singapore does not use daylight saving and shares Perth's time, so the two can be called in the same block. New Zealand's daylight saving starts a week before Australia's, so for that week Auckland is 3 hours ahead of Sydney.

Timing is not only about the first call. Across a cadence, vary the window for each attempt so you catch people with different routines. A buyer who is always in a stand-up at 10am may answer every time at 2:30pm.

Persistence matters as much as timing. It takes 4 attempts on average to reach a decision maker, and 58% of meetings are booked on the fourth attempt or later. Nousu's standard cadence is 8 touches over about 24 days. See the outbound sales guide for a full cadence.

Nousu has not published seasonal connect rates, so treat this as practical planning rather than data. A few points in the Australian year change how buyers respond.

• End of financial year. Australia's financial year ends on 30 June. Budget conversations bunch up either side of it, so problems with a cost attached are easier to discuss in May and July.
• Christmas and January. Many businesses slow down or close between Christmas and the middle of January. Use the period for list building and research, and plan a strong restart.
• School holidays. Senior people take leave in school holidays, which differ by state. Expect more automatic away replies and plan more attempts.
• Industry calendars. Retailers are hard to reach before Christmas, accountants around tax deadlines, and schools at term starts. Ask a customer in the industry when their quiet weeks are.

Nousu's figures are a strong starting point, but your buyers have their own routines. Factory managers start early. Clinicians are free between patients. Retailers avoid weekend trading peaks. Test timing on your own list over a few hundred dials before changing your whole plan.

Then put your new rates into the meetings per dial calculator to see what the change is worth. Your scripts matter as much as your timing once you connect: start with the cold call scripts library.

The peak windows are averages across director, VP, C-suite and founder-level buyers. Some roles keep different hours. Nousu has not published role-by-role timing, so treat the points below as hypotheses to test with the method above, not as data.

Sector booking guides on our blog cover timing in more depth, for example booking meetings with logistics managers and booking meetings with pharmacy owners.

Knowing the best time to call is worthless if the team spends it in internal meetings. The most common reason SDR teams miss the 10am peak is a stand-up, a training session or a pipeline review scheduled right on top of it.

Calling block: {{market}} peak ({{local_window}} their time)

List: {{list_name}}, {{number_of_accounts}} accounts researched
Focus: {{attempt_number}} attempts and booked callbacks first
Goal for this block: {{target_conversations}} conversations

No meetings, no email, no chat. Log outcomes straight after each call.

Every peak window loses to one thing: a callback time the buyer chose. When a gatekeeper or the buyer says to call back on Thursday afternoon, that time beats any average. Treat callbacks as appointments, not as tasks.

• Book every callback into the calendar with the exact time and the buyer's local time zone.
• Call on the minute. A callback a few minutes late feels like any other cold call.
• Open by reminding them they suggested the time: it changes the tone of the call.
• If they do not answer, try once more within the hour, then log a new attempt for the next peak window.

Gatekeepers are a good source of callback times. When an assistant says their manager is in meetings all morning, ask when they are usually free, and book that time. A callback time from the person who manages the calendar is better than any average, and calling exactly when they suggested shows the assistant you listened, which makes the next call easier too.

Callbacks are one reason persistence pays. It takes 4 attempts on average to reach a decision maker in Nousu's data, and many of those attempts are callbacks booked on earlier calls.
