The short version

  • Each has a real cost: Bonfire it is a sourcing and evaluation tool rather than full procure to pay, so requisitions, purchase orders and invoicing stay in the finance system and the join between them is the agency's problem.; Trimble Unity Maintain esri ArcGIS is a hard prerequisite, so an organisation without it faces a second substantial licence and a GIS programme before the maintenance system can be used at all.
  • They diverge on capability: Bonfire covers Solicitation posting, Trimble Unity Maintain covers Built on ArcGIS.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bonfire

  • It is a sourcing and evaluation tool rather than full procure to pay, so requisitions, purchase orders and invoicing stay in the finance system and the join between them is the agency's problem.
  • Since the acquisition path from GTY to GI Partners to Euna Solutions, Bonfire sits in a portfolio alongside products it once competed with, which narrows a shortlist that appears independent.
  • Suppliers must register on the portal to bid, and small local vendors reliably complain about the extra account, which can reduce responses on low value solicitations.
  • Pricing is quoted rather than published and scales with solicitation volume, so an agency with a few very large procurements pays a model designed around throughput.
  • Contract management after award is thin compared with dedicated contract lifecycle products, so agencies often buy a second system for the obligations the award created.

Trimble Unity Maintain

  • Esri ArcGIS is a hard prerequisite, so an organisation without it faces a second substantial licence and a GIS programme before the maintenance system can be used at all.
  • The product is mid-rename from Cityworks to Trimble Unity Maintain with transition timelines Trimble has not committed to publicly, leaving contracts, documentation and integrator experience split between two names.
  • CVE-2025-0994, a deserialisation flaw in Cityworks, was exploited in the wild and listed by CISA in February 2025, which makes on-premise deployments a patching obligation rather than a set-and-forget install.
  • Because assets live in the GIS, changing the asset model is a GIS division change, so maintenance teams cannot restructure their own hierarchy without another department in the loop.
  • It is built for North American public sector practice, and the permitting, funding source and reporting models do not map cleanly onto other countries or onto private industrial estates.

Answered from the vendors’ own pages

Bonfire: Who owns Bonfire?

Euna Solutions. Bonfire was acquired by GTY Technology in 2019, GTY was taken private by GI Partners in 2022, and the portfolio was rebranded Euna Solutions in 2023.

Trimble Unity Maintain: Is Cityworks discontinued?

Not discontinued, renamed. It is becoming Trimble Unity Maintain, converging with AgileAssets, and Trimble has not published a final transition date.

Bonfire: Is it full procure to pay?

No. It covers sourcing and evaluation through award. Purchase orders and invoicing remain in the finance system.

Trimble Unity Maintain: Do I need Esri ArcGIS?

Yes. The product is built on ArcGIS and cannot be deployed without an Esri licence.

Bonfire: What is the real value?

A defensible, time stamped evaluation record when an award is protested, which is the expensive failure mode in public procurement.

Trimble Unity Maintain: Was there a security incident?

Yes. CVE-2025-0994 in Cityworks was exploited in the wild and added to the CISA known exploited vulnerabilities catalogue in February 2025.

Bonfire: Can we see what other agencies pay?

Yes. These contracts are public records. Read several comparable awards before negotiating.

Trimble Unity Maintain: Can it handle roads and pavement as well as pipes?

Yes, through the AgileAssets lineage now inside the Unity Maintain family, which adds linear referencing for transportation assets.
