Frequently Asked Questions
Create separate line items on your IT support invoice for each service type. If you provided 4 hours of troubleshooting at $85/hour and also sold a network switch for $320, list them as distinct items. This approach gives clients clear visibility into what they're paying for and makes it easier to defend charges if questions arise. It also simplifies tracking which work was time-based versus fixed-price for your business records.
GST at 15% applies to most IT services in New Zealand. Calculate the subtotal of all line items (hourly support, consulting, equipment sales, software), then add 15% GST. The GST amount and total must be shown separately on your invoice. Professional IT support invoices should clearly state you're GST-registered and display your IRD number. If you're not GST-registered, you cannot charge GST separately, though you may note this on the invoice to avoid client confusion.
Include the date and time range of support provided, a clear description of what was addressed, and your hourly rate. For example: "Remote support - 2 hours at $85/hour - diagnosing and resolving email server connectivity issues." Specific descriptions help clients understand the value delivered and reduce payment disputes. If you provided multiple support sessions, list each separately with dates so the client can match them to their own records and understand the invoice timeline.
Yes. Software licensing, whether perpetual or subscription-based, can be itemized on the same invoice as service charges. List software separately from labour—for example, "Annual Antivirus Licensing - 12 seats at $45/month" on one line and "Software installation support - 4 hours at $85/hour" on another. This separation clarifies what's a fixed product cost versus billable time. Many clients appreciate seeing these distinctions because it helps them budget for recurring costs and understand one-time setup fees.
List retainer charges as a monthly or quarterly line item with the fixed amount and billing period. For example: "Managed IT Support - Monthly Retainer (July 2025) - $1,500." If the retainer includes a set number of hours, state this on the invoice to set expectations. Any usage beyond the included hours should be billed separately as overage charges. This structure makes recurring costs predictable for both you and the client, and clearly documents what's included in the base retainer versus additional services rendered that month.
Be specific enough that the client can match the invoice to their request or conversation, but don't over-document. Instead of "General IT support," write "Network configuration and testing for office expansion to second floor." A good invoice description answers: what was done, why it mattered, and which system or area it affected. This level of detail reduces disputes, helps clients track their own records, and demonstrates the value of your work without becoming unnecessarily verbose.
New Zealand invoices must include your business name and IRD number (if GST-registered), invoice date and number, client's name and address, itemized description of services, amount due, and GST (if applicable). The invoice number should be unique and sequential. Keep copies for at least 7 years for tax purposes. There's no mandatory payment term, but stating your terms (e.g., "Due within 30 days") on the invoice prevents confusion. Digital invoices are acceptable if stored securely.
List these as separate line items to clarify labour differences. Example: "On-site hardware installation - workstation upgrades - 3 units at $150/unit" and "Remote IT support hours - setup and configuration - 6 hours at $85/hour." On-site work may justify higher rates due to travel time, equipment handling, and setup complexity. Separating these services helps clients understand pricing differences and allows you to track which services require site visits for accurate scheduling and resource planning.
