Before using any published price range, confirm the scope, measurements, substrate condition, prep level, number of coats, paint system, access, exclusions, waste, GST, and target margin. You should also separate labour from materials so you can see whether the job is profitable.
Use these price ranges as a starting point, then build a structured quoting workflow: capture the enquiry, inspect the site, measure the work, build the quote, send it, follow up, schedule the crew, track job costs, and invoice. ATT is built to keep that full workflow together for New Zealand painting and decorating businesses.
When comparing options, you should look beyond feature lists and test the workflow that makes money: quote speed, customer follow-up, scheduling, subcontractor updates, timesheets, supplier costs, progress invoices, Xero sync, reporting, and flat plan pricing.
Competitor features, pricing, and integration scopes change over time. Treat this comparison as a decision guide, then check current vendor pricing, integration terms, and plan limits before switching systems or committing a team workflow.
Yes. Bundling both projects saves 10–15% compared to doing them separately, since the painter only mobilises once and can optimise their schedule around weather delays.
Interior paint lasts 10–15 years in normal conditions. Exterior paint lasts 7–10 years in NZ's climate (less on coastal or north-facing surfaces). Premium paint and proper preparation extend both.
This is a popular approach in NZ. Interior painting is relatively DIY-friendly (no height work, no weather concerns). Exterior is best left to professionals for safety and quality, especially for two-storey homes.
Include scope, prep, materials, access, labour, subcontractors, waste, GST, and margin. The range is only useful once those assumptions are explicit.
Review comparisons whenever vendor pricing, integrations, plan limits, or workflow requirements change. For software decisions, check current vendor pages before buying.
