A practical guide to fixed-price ERP implementation for Australian and New Zealand businesses, covering what fixed price includes, when it fits, and the questions to ask before you commit.
What fixed price should mean
A fixed-price implementation is an agreement where the total cost of the project is defined before work begins, based on an agreed scope, set of deliverables and assumptions. The price does not change unless the scope changes, and any scope change is agreed and priced before the additional work proceeds.
This is different from an estimate, a target or a not-to-exceed figure. A genuine fixed price means you know the investment before you commit, and the partner carries the risk of delivering within that price. If the project takes longer than expected, the partner absorbs the cost. If the project runs into complexity that was within the agreed scope, the partner resolves it without sending an extra invoice.
A fixed price is not a guess. It is a commitment from the partner that they have understood the scope, assessed the risk, and priced the work accordingly.
What a fixed-price implementation includes
A well-structured fixed-price ERP implementation should include clearly defined deliverables, a documented scope, a set of assumptions about what your team will provide, and a delivery plan with milestones. It should cover configuration, data migration, testing, training and go-live support, with the specific activities spelled out so there is no ambiguity about what is in and what is out.
It should also include a clear statement of what is not included. Integrations, customisations, additional modules or data migration beyond the agreed scope are typically priced separately, but the key is that these are identified before the project starts, not discovered halfway through.
When fixed price works
Fixed price works best when the scope is well-defined and the business processes fit within the standard capabilities of the platform. If you are implementing core finance, or finance and distribution, with proven templates and a clear set of requirements, a fixed-price approach gives you predictability and keeps the project focused.
It also works when the business is ready to make decisions, provide data on time and commit people to testing and training. A fixed-price project still needs your team's involvement. The difference is that the responsibilities are defined up front, so delays on one side do not silently inflate the cost on the other.
When fixed price is the wrong fit
Fixed price is not the right approach for every project. If your requirements are still being defined, if you are redesigning core business processes, or if you need complex multi-system integrations that cannot be scoped with confidence, a fixed price can create pressure to cut corners rather than deliver the right outcome.
In those cases, a phased or tailored engagement is more honest. You start with a discovery phase to define the scope, then move to a fixed-price delivery once the requirements are clear. A good partner will tell you this up front, even if it means a smaller initial commitment.
Questions to ask before you commit
Before you sign a fixed-price agreement, ask the partner these questions. The answers tell you whether the fixed price is real or just a number.
What exactly is included in the scope, and what is explicitly excluded? If the partner cannot answer this in writing, the fixed price is not fixed. What assumptions is the price based on? If the price assumes your team will provide clean data, attend workshops and approve deliverables within a timeframe, those assumptions need to be stated. What happens if the scope changes? A genuine fixed-price agreement includes a change control process that is agreed before work begins, not invented when a change is requested.
Who from the partner's team will be working on the project, and what is their experience? A fixed price is only as good as the people delivering it. Ask for named individuals and their track record with similar businesses.
Rapid Results: Conexio's fixed-price approach
Conexio's Rapid Results methodology is a fixed-price approach to implementing Dynamics 365 Business Central for ANZ mid-market businesses. It uses proven templates, focused scope and structured delivery to give you a defined investment, a clear plan and a predictable go-live.
Rapid Results works in four phases: Envision, where we agree priorities, scope and outcomes; Refine, where we configure and test with your real data; Onboard, where we prepare your team and data for go-live; and Launch, where we manage cut-over and support you through the first month-end close. Every phase has defined activities, deliverables and responsibilities, so you know what is happening, what your team needs to do and what comes next.
The fixed price covers the agreed scope, deliverables and Conexio responsibilities documented before implementation begins. If a requirement is outside the scope, it is discussed and agreed before additional work proceeds. There are no surprise invoices.
The bottom line
Fixed-price ERP implementation is not a marketing term. It is a delivery model that gives you certainty over cost, scope and outcome. It works when the scope is defined, the partner is experienced and the business is ready to participate. It does not work when any of those three things are missing.
If you are planning a Business Central implementation and want to understand whether a fixed-price approach fits your business, the most useful next step is a conversation. Bring your current systems, your pain points and your timeline. We will give you an honest view of fit, effort and next steps, including when fixed price is not the right answer.
