The short answer
There is no reliable single price for custom software in New Zealand. A useful price depends on the job, users, data, integrations, exceptions, acceptance checks, hosting and support.
BestAI has a public offer that starts from NZ$399 for a focused tool, with eligible confirmed scopes able to target 48-hour delivery. That is a BestAI starting offer, not a New Zealand market benchmark. It applies only after the scope fits.
Before requesting a custom build, decide which of these four paths you actually need:
- Use an existing specialist product.
- Configure a feature in software you already use.
- Build one focused tool for a clear remaining gap.
- Scope a larger system or a bounded workflow separately.
Start with the existing product
Existing software is usually the right first choice when the task belongs to a mature category. Examples include accounting, payroll, booking, construction estimating, takeoff, job management and regulated records.
Use a trial or demo with a real piece of work. Do not judge a product only from a feature list. Check whether it handles the actual input, output, staff roles and exceptions your business sees.
Choose the existing product when it:
- Covers the core job without repeated manual workarounds
- Keeps records in the system where the team already works
- Has the permissions, support and export options you need
- Avoids rebuilding category features that a specialist vendor already maintains
Configure before you commission
Many apparent software gaps are configuration gaps. Before building anything, check:
- Templates and custom fields
- Native forms and reports
- Approval rules
- Export formats
- Existing integrations
- Account or permission settings
A small process change or a better template may solve the problem with less ongoing risk than new code.
When a focused custom tool may fit
A focused tool is easier to scope when it has:
- One clear input
- One clear output
- A small, named group of users
- Limited and understood exceptions
- No unresolved system access
- Examples that define what an acceptable result looks like
Illustrative shapes include a structured form that creates one internal record, a branded document draft from approved inputs, or a calculator companion that prepares a staff-reviewed result.
These are shapes, not claims that BestAI has delivered a particular customer outcome.
What changes the scope
The following factors usually matter more than a feature count.
| Scope factor | Smaller focused scope | Broader scope |
|---|---|---|
| Users | One role with the same access | Several roles with different permissions |
| Data | New, structured input | Migration, sensitive records or inconsistent history |
| Systems | Standalone or verified access | Several systems or unclear APIs |
| Exceptions | A short known list | Many judgement calls or changing rules |
| Output | One draft, record or calculation | Multiple workflows, reports or downstream actions |
| Acceptance | A few agreed examples | Complex quality, security or operational testing |
| Support | Clear handover | Monitoring, incident response or ongoing iteration |
If the broader column describes the need, ask for a separate scope. Do not force it into a starting offer.
Integrations must be verified
A product name is not proof that an integration is possible. Before any connector is promised, verify:
- The current API or supported export
- The account tier and permissions
- Test access
- Data fields and limits
- Authentication and ownership
- Failure handling
- Who approves live access
If these are unresolved, the price and timing are unresolved too.
Focused tool or bounded workflow
A focused tool normally creates one useful output. A workflow moves a repeated task between people, records or existing systems.
Use the Digital Employee workflow method when the task crosses systems, needs explicit approvals or has important exceptions. The workflow should be mapped before any automation is proposed.
For estimating, takeoff, cost build-up, scheduling, job costing, variations or invoicing, start with specialist construction or trade software. The NZ tradie quoting software decision guide explains that route.
A practical scope note
Write these seven lines before requesting a quote:
- Current method
- Specialist or native software already checked
- Exact input
- Exact output
- Users and permissions
- Exceptions that must stop for a person
- Two or three acceptance examples
If those lines are difficult to complete, the useful next step is discovery, not a delivery promise.
BestAI's public offer boundary
BestAI's focused custom-software offer starts from NZ$399. Eligible, confirmed scopes can target 48-hour delivery. The starting offer does not automatically cover unresolved integrations, several user roles, complex migration, sensitive data, high-impact decisions, a full mobile platform, a CRM or ERP replacement, or ongoing support.
The focused custom software service page shows the full decision path. If the real need is customer discovery and a clear online presence, start with website plans and public work instead.
Next step
Send the seven-line scope note through the contact form. BestAI will check the fit before treating the starting price or delivery target as applicable.
This guide does not provide a market-wide price range because no current, like-for-like dataset has been registered for that claim.
