Works with what you already use.
Coordinate with Procore on the jobs that need it, keep QuickBooks as your books, import the schedule from P6, connect to your subs' and GCs' accounts, and build on the same permissions with the API.
No card to start · one job free · subcontractors and viewers are free · everything exports as PDF or CSV
Procore coordination for the jobs that need it.
Import projects, the directory and cost codes; pull and push RFIs and submittals; send daily logs, manpower and production quantities. We switch it on with you per account.
Plans: Company and Business
QuickBooks stays your books.
Send reviewed, approved time to QuickBooks, and import bill and expense lines charged to the job into job cost, mapped to cost codes and never counted twice. Sage 300 CRE and CSV imports work the same way.
Plans: Every plan, including the free Solo plan
Import from Primavera P6 or Microsoft Project.
P6 XER (tasks and links) and Microsoft Project XML import into the critical-path schedule, idempotently by task ID, so you can re-import an update.
Plans: Every plan, including the free Solo plan
Your GC's or your subs' YakProject accounts.
A subcontractor's own account connects to a GC's job and sends hours, daily reports, certified payroll and pay applications from its own records. Wages never cross.
Plans: Every plan, including the free Solo plan
How it works for subsBuild on the same permissions.
Scoped API keys, OAuth 2.1 apps and an MCP server for AI assistants such as Claude, each limited to the person's role, the areas granted and the jobs chosen. Signed webhooks announce changes. Writes from a credential create drafts or proposals; nothing submits, approves, signs or pays.
- API keys, OAuth and MCP on every plan, rate-limited per credential.
- Signed webhooks on Company (5 endpoints) and Business (25).

Is the API on the free plan?
Yes. API keys, OAuth apps and the MCP server are on every plan. Outbound webhooks start on Company.
Can an AI assistant approve or sign something?
No. Credentials can never sign, certify or approve money or legal records. The MCP tools create drafts and proposals that a person accepts.
