Most procurement conversations focus on cost. The bigger risk with digital programs is not the price. It is what happens after you sign.
Governments regularly end up in long contracts where the supplier owns the platform, the data sits inside it, and changing something as small as a report layout needs a variation, a quote, and a wait. The capability you bought to make you faster has made you dependent on it. This is vendor capture, and over ten years, it is more expensive than almost any day-one overrun.
Why does it keep happening?
It happens because the government tends to buy digital capabilities as a single, integrated platform from a single supplier. That feels simpler at the point of purchase. One contract, one supplier to hold to account, one go-live. But it bundles two very different things into one dependency. The durable foundation you should keep for years, and the disposable tools that should change as needs change. Tie them together, and you are locked to the supplier of both.
Separate what you keep from what you replace.
The durable part is your data and the interfaces to it. Asset registers, spatial data, the common identifiers that let datasets join. This is the asset. You should own it, host it where you control it, and require that it remain accessible via open interfaces, regardless of who builds the tools on top of it.
The disposable part is the applications. Dashboards, calculators, models. These should be cheap to build, easy to switch off, and never the thing that holds your data hostage. If a better tool comes along, or a supplier underperforms, you should be able to replace the tool without touching the foundation.
Buy through structures that assume change.
Three practical moves protect you.
Specify ownership and exit up front. Make clear in the contract that the agency is the data controller, that data can be exported in open formats at any time, and that the supplier hands over cleanly at the end. If exit is hard to write, that is a warning about the dependency you are creating.
Use panels and marketplaces rather than fresh procurement each time. New Zealand’s All-of-Government contracts and Australia’s Digital Marketplace let you call off pre-qualified suppliers for individual builds without bypassing competition. This keeps tools contestable and stops any one supplier from becoming the only option.
Require open interfaces as a condition, not a nice-to-have. The moment your data is only reachable through one supplier’s product, you have lost the ability to choose. Open interfaces are what keep the market open to you.
The point
Buying well is not about squeezing the lowest price from a single supplier. It is about structuring the deal so that you keep control of what lasts and stay free to change what does not. Get that separation right, and procurement stops being a one-time gamble and becomes a series of smaller, reversible decisions.
