Pricing & cost

Pricing ModelQuote-only / Custom pricing. Key2Act (operating under its original name, WennSoft, for its Signature platform) does not publish public pricing tiers or standard per-user/per-tech rates. Pricing is customized and available only via direct contact with the vendor or authorized channel partners.

Typical CostPricing is non-public. Specific dollar amounts per user, technician, or month are not publicly disclosed by the vendor and require a customized quote based on business size, user count, and deployment requirements.

Api Or Integration FeesSeparate costs apply for add-on modules (such as Signature Time, Signature Telematics, and Cloud Document Storage) and third-party integrations (e.g., Quadra quoting software, wsTOOLS). Industry reviews note that specialized workflows and integrations often require additional customization expenses and add-on fees beyond base licensing.

Implementation CostImplementation and onboarding fees are quote-based and depend on partner consulting, scope of setup, data migration, and Business Process Reviews. Industry analyses note that implementation relies on specialized consultants and frequently involves custom development expenses.

API & data access

Has ApiYes

Api TypeRESTful JSON web service

Api Access GatingGated behind paid licensing and customer agreement; installed on-premises behind a firewall for Microsoft Dynamics GP / Signature customers, with documentation restricted to the customer support portal.

Api LimitationsSupports GET and POST operations across service call and job endpoints; technical rate limits, custom field caps, and specific missing fields are not publicly disclosed.

Data Export OptionsDirect SQL Server database querying via SSMS, SQL Server Reporting Services (SSRS) reports, Microsoft Dynamics GP SmartLists / SmartList Builder, and Power BI.

Native AI features

Ai Features SummaryLegacy Key2Act Signature (built on Microsoft Dynamics GP) contains essentially no native AI features. In early 2026 (showcased at AHR Expo 2026), parent company WennSoft announced its next-generation cloud-native platform, WennSoft FORGE / Nexus (connected to Microsoft Dynamics 365 Business Central), which incorporates an embedded AI assistant named 'Wennston' powered by Azure AI Foundry to assist with system setup, task template drafting, and workflow guidance.

Ai DispatchKey2Act / Signature has no shipped native AI-powered dispatching or scheduling features, using traditional rule-based graphical schedule boards in its legacy GP platform. Further AI-assisted dispatching tools are planned/roadmap items for the next-generation FORGE platform integrated with Microsoft Dynamics 365 Business Central and Copilot.

Ai FinanceKey2Act / Signature has no native AI invoicing, AI estimating, or AI AP/AR automation built into its legacy GP product. Financial and job-costing processes rely on standard GP transaction logic or third-party integration add-ons.

Ai Assistant Or McpKey2Act / Signature does not offer a Model Context Protocol (MCP) server or a native copilot in legacy Signature. For its next-generation FORGE platform, WennSoft introduced 'Wennston' (powered by Azure AI Foundry), an embedded AI assistant that helps draft task templates and guides users through operational workflows.

Integrations & ecosystem

Accounting IntegrationsKey2Act (Signature / WennSoft) is natively built for and integrated with Microsoft Dynamics GP and Microsoft Dynamics 365 Business Central (via WennSoft FORGE). It does not offer native out-of-the-box integrations for accounting systems like QuickBooks, Sage Intacct, or Foundation; connecting to non-Microsoft ERPs requires third-party integration platforms (such as eOne SmartConnect) or custom file transfers.

MarketplaceKey2Act / WennSoft does not maintain a public app marketplace or public partner directory on its website.

Unified Api SupportUnified API platforms such as Agave and Merge.dev do not support Key2Act / Signature / WennSoft in their standard integration catalogs.

Accounting fit & implementation

Certified PayrollNative support (includes built-in Davis-Bacon Act prevailing wage calculations, rate classes, fringe benefit tracking, and certified payroll reporting).

Accounting MethodAccrual accounting

Wip Poc SupportSupported natively (includes Work-in-Progress (WIP) tracking, WIP reconciliation reports, and Percentage-of-Completion (POC) revenue recognition at both the job and project levels).

Implementation TimeMonths (typically 3 to 12 months depending on organizational complexity and ERP scope).

Requires ImplementerYes (typically requires a paid VAR partner or WennSoft Professional Services).

Adoption & market position

Market PositionWennSoft (formerly known as Key2Act) is an established enterprise field service management, job costing, and equipment management software vendor serving specialty trade contractors. Its primary legacy offering, the Signature suite, is built as a deeply integrated ISV add-on for Microsoft Dynamics GP (Great Plains). In February 2023, the business was acquired by Volaris Group (an operating group of Constellation Software Inc.) from private equity firm LLR Partners.

Customer ScaleServes over 600 customers across specialty trades, facilities maintenance, mechanical, electrical, plumbing (MEP), and asset-centric industries.

MomentumLegacy platform facing transition pressure. Because Signature relies heavily on Microsoft Dynamics GP—which Microsoft is deprecating with end-of-support timelines through 2029/2031—many trade contractors consider it an aging system and are actively migrating to modern cloud-native field service platforms (such as BuildOps, FIELDBOSS, or Dynamics 365 Business Central partners). In response, parent company Volaris Group operates it as a mature asset with long-term GP maintenance while building cloud transition options like ProjectStream 365 on Microsoft Power Platform.

Facts are grounded in public sources (linked above). The AI-readiness tier is a transparent heuristic from API openness, data extractability, native AI, and momentum, not a vendor ranking. This is our assessment as of 2026, not advice; software features and pricing change, and vendors are welcome to correct anything here — verify current specifics with the vendor before deciding.
