Timely
Timely API

One API;
Integrations that stick.

Connect Timely to your existing tools: invoicing, project management, and reporting.
Full OpenAPI 3.1 spec. Self-service, no back-and-forth required.

Three workflows your
team actually needs.

Timely's API is built around the integrations teams ask for most.

Enterprise & agencies

Project import

Your PM tools and Timely, in sync.

Your projects live in Jira, Asana, or Linear — Timely should know about them the moment they're created. Sync automatically, track against the right work from day one, and cut the admin entirely.

See the docs

Consultants & agencies

Invoicing & billing

Approved hours. Automatic invoices.

When a project closes, your hours should flow straight into your invoicing tool — not sit in a spreadsheet waiting to be exported. Connect Timely to Xero, QuickBooks, or FreshBooks and turn approved time into invoices automatically. Fewer errors, faster billing cycles.

Ops & finance teams

Custom reporting

Time data in the dashboards you already use.

Your finance team doesn't want another dashboard. They want the data in the one they already use. Query Timely's API to feed hours into Power BI, Tableau, or any BI platform. Headcount cost, utilization, overtime — live, not lagging.
