Modelled estimate, not a guarantee. Real outcomes depend on doing good work, answering the phone fast, and how aggressively you fill the calendar in the first 8–12 weeks.

What you need to start

▸Commercial vacuum (HEPA, light enough for stairs) — $400–$700
▸Mop bucket, microfibre system, dust mop — $200
▸Eco-friendly all-purpose cleaner, glass cleaner, disinfectant — $100/mo restock
▸Professional rubbish bins, gloves, signage — $150
▸Scheduling / route software (after-hours work needs tight time-tracking) — $40/mo
▸Public liability + theft insurance (essential for after-hours access) — $80–$120/mo
▸Sole App for invoicing — purpose-built for sole traders, NZ launch June 2026

Why this is AI-proof

Vacuuming an office at 9pm, restocking the toilet paper, wiping down a kitchenette someone left a mess in — physical, after-hours, trust-based. Customers want a known person with a key, not a robot in the building when they're not.

The recurring-revenue model that works

Commercial cleaning is the closest a service business gets to SaaS — recurring monthly contracts, predictable revenue, low customer churn. A small office (5–15 staff) needs 1–2 hours of cleaning, 2–5 times a week, paid monthly. Charge $80–$160 per visit, take the workload to 6–10 contracts a week, and you're at $1,800–$3,000/wk on a route you can run solo or hand to staff.

Existing supply skews to either large corporate cleaning companies (slow, expensive, faceless) or one-person operators with no online presence. A new entrant with a website + GBP that ranks for 'office cleaning [suburb]' AND a clear professional pitch (uniformed, insured, after-hours, monthly contract) wins on the discovery side.

What to charge in 2026 NZ

Small office (200–400 sqm), 3× weekly: $1,200–$2,400/mo
Medium office (400–800 sqm), 3× weekly: $2,400–$4,800/mo
Dental clinic / medical (high standards, daily): $1,500–$3,500/mo
Shopfront cleans (single visit, evening): $80–$150/visit
Carpet cleaning (add-on, quarterly): $400–$1,200 per visit
Window cleaning (add-on or sub-out): $300–$1,500 per visit

Funding

Three WINZ programmes can stack to help cover this.

If you're on Jobseeker Support, the Self-Employment Start-Up Payment can cover the kit and insurance. Flexi-Wage adds up to NZ$16,800 over 28 weeks of living costs while you sign your first contracts. Business Training Grant adds up to NZ$5,000.

How to win your first 5 contracts

Walk in. Offer a free trial clean (one visit, free, no commitment). Ask for the office manager or practice manager directly. Bring a printed one-pager (services, rate, references, insurance, photo of you in uniform). Most decision-makers in small offices will say yes to a free trial — and 60-70% of trials convert to paid contracts because changing cleaners is annoying and you're already there. Get five trials and three will sign.

Common questions

Do I need to be GST registered?

Above $60k revenue you must be. Commercial clients prefer dealing with GST-registered suppliers anyway (they claim it back), so register early — most operators register at startup specifically for this reason.

Is a uniform / branded gear worth it?

Yes — strongly. Walking into an office at 7pm in a branded shirt with a printed checklist is a different signal than turning up in jeans and a t-shirt. Costs $150 to set up, lifts your conversion rate dramatically.

When can I start hiring cleaners?

Once you're booked 5+ contracts and one person can't physically cover the route. Most operators hire their first cleaner around month 4–8. Pay above minimum wage — turnover in commercial cleaning is the industry's biggest cost, and the easiest fix is paying $25–$30/hr instead of $22.

Where this works in NZ

Self Made's city guides recommend this idea in the following locations — each links through to the local playbook with suburbs, demand signals and what to expect.

Auckland · NZ

Auckland →

CBD + suburban office market is enormous and fragmented. Most existing operators are large faceless contractors — small independents who answer the phone + run uniformed crews win the small-medium office contracts every time.

Wellington · NZ

Wellington →

Government + corporate office market is dense + recurring. Premium rates if you can demonstrate reliability + uniformed staff — most existing supply is faceless large operators.

Otago · NZ

Dunedin →

University + hospital + suburban office market. Premium rates if you can demonstrate reliability + uniformed crews — most existing supply is faceless contract cleaners.
