Frequently Asked Questions
New Zealand's GST rate is 15% and applies to all car wash services. Add the GST amount to your subtotal and include both the pre-GST and post-GST figures on your invoice so customers see the complete breakdown. Your invoice template should automatically calculate this—if a customer's vehicle requires multiple services like exterior wash, interior vacuuming, and wax application, each service totals to calculate the subtotal, then 15% GST is applied once to the entire invoice total. This ensures compliance with Inland Revenue requirements.
Itemizing services separately is recommended. Breaking down premium exterior wash, interior vacuum, wheel cleaning, and dashboard polish as individual line items helps customers understand what they're paying for and justifies your pricing. Detailed invoicing also simplifies dispute resolution and makes your business appear more professional. It's especially useful for upselling—when customers see each service individually priced, they're more likely to add optional services like wax application or protective coating. Transparency builds trust and reduces payment friction.
Yes, absolutely. Mobile car wash businesses benefit from templates designed for on-site service delivery. Since you're visiting customer locations, the template should allow you to add the customer's address and date of service, include space for digital signatures or payment confirmation, and support quick invoice generation—ideally printable or email-ready immediately after completing the wash. Mobile operators often invoice same-day, so a streamlined template eliminates paperwork delays and keeps your cash flow moving quickly.
Most car wash services operate on immediate or next-day payment terms. Unlike construction or professional services, customers typically expect to pay when the wash is complete or within 24 hours. Include clear payment terms like "Due upon receipt" or "Due within 1 business day" on your invoice. For regular corporate clients or fleet operators, you might negotiate 7–14 day terms if they're reliable customers. Always specify your accepted payment methods and include bank details or payment processor information so customers know exactly how to pay.
List add-on services as separate line items with their own rates. Common add-ons include wax application ($30–50), interior detailing ($20–40), protective coating ($25–45), and window tinting ($15–25), depending on your market and vehicle type. By itemizing each add-on, you encourage upselling and make the customer's total transparent. If a customer declines an add-on initially but changes their mind mid-service, you can easily adjust the invoice. Clear pricing for extras also prevents disputes about final charges.
Send invoices immediately after service completion, ideally while the customer is still present or within the same business day. For mobile car wash services, printing or emailing the invoice on-site creates a professional impression and reduces payment delays. If the customer isn't available immediately, send it within 24 hours. For corporate or repeat customers who receive regular services, you might batch invoices weekly. Prompt invoicing also makes it easier to follow up on late payments and keeps accurate records for GST reporting.
Yes, a flexible template works across all vehicle types. Your service rates might vary by vehicle size—cleaning a van costs more than a motorcycle—but the template structure remains the same. Simply adjust quantities or service rates based on the vehicle being serviced. Include a "Vehicle Description" field on your template (year, make, model, or registration number) to track which vehicle received which service. This level of detail is especially useful if a customer disputes charges or if you maintain customer service history for loyalty programs or maintenance reminders.
Yes, mandatory. New Zealand tax law requires you to retain all invoices and supporting documents for at least 7 years. Keep copies of every car wash invoice you issue, payment receipts, and bank deposits, which form your GST return evidence. Store invoices both digitally and in hard copy if possible. Your template should include invoice numbers and dates automatically to ensure sequential, auditable records. Organized invoice records not only satisfy IRD requirements but also help you identify your most profitable services, track seasonal trends, and support business growth planning.
