BPlus goes live with BUILD Software and Exact Online:
how a complex project workflow is translated into a single integrated system
One-sentence summary
Bplus has gone live with BUILD Software for estimating, site management, project flow, and management reporting, combined with Exact Online for accounting; the migration away from Microsoft Navision was fast, with BUILD restructuring all core construction processes without customization.
The trigger: when an ERP outgrows itself
Every construction company knows the scenario. You choose an ERP system when it fits your size and processes. Years later, you’ve grown, refined your approach, and your way of working has become more specific. The system doesn’t keep up.
That was also the case at Bplus. Microsoft Navision had done its job for years, but the reality of a modern villa builder doesn’t fit easily into a generic ERP. A triple estimation flow (preliminary study, study agreement, final construction contract), with variants per project phase. Milestone invoicing with price revisions per site, running in parallel with progress-based statements. A high volume of variations, because in high-end villa construction every client request results in a contract adjustment. Separate VAT schemes for renovation (6%) and new build (21%) within the same contract.
That complexity doesn’t sit in the tool. It sits in the trade.
Why do construction companies choose a construction-specific ERP?
Because generic ERP systems treat construction processes as custom exceptions, while for contractors they are daily practice. A construction-specific ERP starts from the construction process: estimation as the foundation, the site as a cost center, milestone invoicing as the norm, price revision as built-in logic, and variations as a standard workflow.
For b+, this meant: no more Excel workarounds to calculate indexation per milestone. No more manual splitting between the main contract and other agreements. No more double data entry between estimator, administration, and accounting. And above all: one system that brings together the entire Bplus process, instead of disconnected tools each covering only part of it.
What makes the Bplus approach unique?
Bplus estimates three times (in different phases) before a project starts. That’s not inefficiency, it’s exactly why their clients know what to expect.
This approach requires a system that thinks along with the process, not a tool you have to force the process into.
The journey: from kick-off to go-live
The main steps:
What changes in daily practice for Bplus?
How does an ERP migration work in construction?
In broad terms: process analysis, data model setup, integrations, data migration, training, and phased rollout. What made Bplus’s trajectory unique was the speed: a fully configured, construction-specific system, fully integrated with accounting, without customization. What required custom work in Navision came standard in BUILD.
The key success factor isn’t the software, it’s the willingness to rethink processes before implementing them in a new system. An ERP migration without a process reset is an expensive copy-paste exercise.
What does this go-live mean for BUILD Software?
Bplus operates in the high-end segment of Belgian villa construction, a niche where every project is unique and demands high standards in preparation, finishing, budget control, and client communication. Their triple estimation approach, the volume of variations, and parallel revenue and execution tracking required a system that brings all these flows together.
That’s exactly the type of collaboration BUILD Software is built for: a construction-specific system that covers the client’s full process, refined together with the client, without customization.
Considering making the switch yourself?
An ERP migration isn’t an IT project. It’s a process reset that starts with an open conversation about your current challenges.
