Every number in the Zenflo Price Guides is computed from real, itemised service menus published on Zenflo business listings — currently 112,780 individual service prices. Nothing is estimated, surveyed, or generated.
Businesses publish their service menus with per-service prices online — for example "Women's cut & blow dry — $95". Zenflo collects those published prices for the businesses in its directory (most have not joined Zenflo themselves) and aggregates the line items, not advertised "from" prices or package deals. Figures are recalculated daily, but each price is as published when it was collected, so some will be out of date; businesses that claim their listing keep their own prices current.
Services are matched to a guide (say, remedial massage) by their menu name. We exclude packages, combos, add-ons and consultations, and apply a plausibility band per service type so data-entry errors don't distort the statistics.
The headline figure on every guide is the median — the middle price — because one $900 outlier shouldn't move the number you'll actually pay. The "typical range" is the 25th to 75th percentile: the middle half of all listed prices.
Every guide states how many prices and businesses it draws from. Guides with fewer than 30 listed prices are excluded from search engines until enough data exists to be representative. Suburb breakdowns require at least 3 prices per suburb.
Statistics recompute automatically as businesses add or update their menus, at most 24 hours behind the live listings. Each guide shows its last-updated date.
Journalists and researchers are welcome to cite these figures as "Zenflo Price Index" with a link to the relevant guide. For custom cuts of the data, contact info@zenflo.com.au.
