Accurate Invoicing
for Every Project

Project invoicing software turns project work into accurate invoices for project-driven businesses. Unlike standalone invoicing tools, it connects hours, expenses, rates, and billing rules to the project they belong to, so the invoice reflects the real work delivered. TimeLog is a project financial management platform that handles this and sends the data directly into your accounting system.

Yes. In TimeLog, each billing rule is attached to the work it covers. A project can run a fixed fee for a design phase, hourly billing for delivery, and prepaid hours for support, all at once. When the invoice is generated, the rules calculate and combine automatically, so the invoice reflects exactly how the contract was structured.

TimeLog connects directly to leading accounting and ERP systems including e-conomic, Visma, Fortnox, Business Central, and Dataløn. Invoice data flows from TimeLog into the system you already use, so there is no manual re-entry between platforms. Connections beyond the named systems are supported via API.

Work in progress (WIP) is the value of work delivered but not yet billed. Revenue recognition is the accounting view of revenue earned in a period. Both are tracked inside TimeLog alongside invoicing, with real-time visibility into what's billable, what's been invoiced, and what's recognized as revenue. Finance teams get the full financial picture of every project without rebuilding it manually.

Invoice approvals work best when the approval happens upstream, on the work itself. Project managers approve hours and expenses as they're logged, finance reviews the invoice before it goes out, and the audit trail captures each step. This avoids last-minute corrections and keeps billing aligned with what the client agreed. TimeLog supports this workflow inside the invoicing process, so every invoice starts from work already signed off.
