How Much Does It Cost to Build a CRM from Scratch?
Building a CRM from scratch with an Australian team typically costs $30,000 to $60,000 for a small first version and $60,000 to $200,000 for a full system, with large or regulated builds going past $250,000. Those are general market ranges. What this guide adds is where the money goes: the share of the budget each phase takes, the running costs that follow, and the two cheaper paths worth checking before any of it is spent.
The figures in this article are general market ranges for Australia, collected for guidance only, and they change. High10 does not publish package prices; every job is quoted in writing after a short scoping call.
Where the money goes, phase by phase
On a typical first version, the budget splits roughly like this. The proportions matter more than the totals, because they show where a cheap quote has cut corners.
Discovery and design, 10 to 15 percent. Workshops with the people who will use it, the list of daily tasks, the one-page diagram of records and how they relate, screen designs for the main tasks. Quotes that skip this phase are not cheaper; they move the thinking into the build, where it costs more.
Core build, 40 to 50 percent. The records, the screens for the daily tasks, user roles and permissions, search, and the plain plumbing that every system needs: logins, audit trail, backups.
Integrations, 10 to 20 percent. The accounting package first, then email or calendar, then anything else. Australian agencies commonly price each integration at $5,000 to $20,000 depending on the system on the other end; one Perth agency’s 2026 guide gives that range and puts a full custom CRM at $60,000 to $200,000.
Data migration, 5 to 15 percent. Cleaning and loading the contacts and history from spreadsheets and old systems. The share rises with the age and mess of the old data.
Testing, training and launch, 10 to 15 percent. Testing by the developer and by your staff, a parallel run, training by task, and the launch itself.
Your own time sits outside these figures: workshops, reviews, testing, and the person who owns the system afterwards. On a first version it is commonly two to four weeks of someone’s time spread across the project.
What makes a build expensive
Many record types with complex relationships. Many user roles, each with its own screens and permissions. Many integrations, especially with systems that have poor interfaces. Workflows with approvals and exceptions. Old, dirty data. And a scope that keeps growing, which is the most common cause of all. The defence against the last one is a first version limited to the daily tasks, with everything else written down for later.
The costs after the build
Hosting, backups and security: a few hundred dollars a month for a small system, a few thousand for a large one. Maintenance and small improvements: typically 15 to 20 percent of the build cost each year. Support: a retainer or an hourly rate. Occasional larger additions as the business changes. Over five years these usually equal or exceed the original build, and the comparison against a subscription product should include them.
The two cheaper paths to check first
A subscription CRM, configured properly. HubSpot, Zoho, Pipedrive and Dynamics, set up by someone who knows them, with the integrations connected. For most businesses under fifty users this costs a fraction of a build over five years. A build from scratch is justified only when the business’s process does not fit these products after an honest attempt.
A low-code platform. For a simple data model and one team, a low-code tool can produce a working system in weeks. It tends to struggle with complex relationships, many roles and integrations, so it suits the simpler end of the custom spectrum and is worth a trial before a full build.

A worked example
This is a hypothetical, not a client. Take a Hunter Valley wine wholesaler with 15 staff. Its process links trade customers to accounts with their own pricing, to standing orders, to allocations of limited vintages, to deliveries, and to invoices in MYOB. Subscription CRMs handled contacts and deals and nothing else. A first version is scoped to the seven daily tasks, two roles, and the MYOB link. The quote lands in the $45,000 to $60,000 band: discovery and design about $7,000, core build about $25,000, the MYOB integration about $8,000, migration of six years of spreadsheet orders about $5,000, and testing, training and launch about $7,000. Twelve weeks. Running costs afterwards are budgeted at around $10,000 a year including a small monthly retainer for improvements. The business compares this against five years of a mid-tier subscription for 15 users plus the cost of making it fit, and goes custom because the allocations and standing orders are the business, and no subscription product handled them.
Security is in the budget, not an extra
A CRM holds personal information. Under the Privacy Act’s APP 11 the business must take reasonable steps to protect it and destroy it when no longer needed, and the OAIC’s guide to securing personal information is clear that outsourcing the build does not move that obligation. Australian hosting, multi-factor authentication, per-person access, backups and an audit trail belong in the core build line, not in a later phase.
How High10 helps
High10 builds custom CRM systems for Australian businesses whose process does not fit the subscription products, and configures HubSpot and similar products where they will do. We tell you which at the first call. Every quote is broken down by phase so you can see where the money goes, the first version is scoped to the daily tasks, and you own the code and data from day one.
Frequently asked questions
What is the cheapest way to build a CRM?
Configure a subscription product properly, or try a low-code platform for a simple data model. A build from scratch is the most expensive route and is justified only when the business’s process does not fit the alternatives after an honest attempt.
How much does a CRM developer charge in Australia?
Senior Australian developers commonly charge $150 to $250 an hour, higher in Sydney and Melbourne, as a general market range. Most agencies quote a first version at a fixed price rather than by the hour, which is the safer arrangement for a defined scope.
Which phase of a CRM build costs the most?
The core build, at roughly 40 to 50 percent of a first version. Integrations and data migration are the phases most often underestimated, because the system on the other end and the old data are never as tidy as expected.
What does High10 charge to build a CRM?
We do not publish package prices. Every project is quoted in writing after a scoping call, broken down by phase, with the first version limited to the daily tasks so the figure is one you can check against the work.
