Unrecorded changes & missing approvals

Builders and subcontractors whose project changes are discussed across site notes, email and photos before reaching the office.

Additional work can start with a short instruction on site. By the time the office prepares a variation, the original scope, supporting photos and approval trail may be in different places. Rebuilding that record takes time, and an incomplete record can make a commercial discussion harder. The useful first step is a clear account of what changed and what is still missing.

Build on the foundation

How the services fit together.

OpenProject provides the project record, Nextcloud holds the supporting files, and n8n provides the integration layer. Together they give you a base for building variation registers and review processes around each project.

An example application

Put the services to work.

For example, a site photo and change request could be saved in Nextcloud, linked to an OpenProject work package and routed to the project manager using n8n. Pricing and approval remain part of your project process.

Adapt it to your business

Adapt the record fields, project permissions and approval stages to your contracts and team. Connections to existing estimating or project systems can be built on the same foundation.
