From Hours to Minutes: Why Batch Billing Changes Everything

Most time trackers treat invoicing as an afterthought. For a freelancer with a single client, it's fine. But if you're managing 5, 10, or 20 projects, the "Standard Workflow" is a disaster. You spend your Saturday clicking through tabs, double-checking hourly rates, and manually downloading files. It's slow, it's prone to errors, and it's soul-crushing.

Chronum's Batch Invoice Generator was built by developers who hate routine. We've replaced the "Open-Edit-Save-Export" loop with a high-speed billing factory. By linking your invoice templates to your projects, Chronum prepares everything in advance. You just review, confirm, and export. It's not just a feature; it's your Saturday afternoon back.

Task-to-Invoice Selection

Turn Any Task List into an Invoice in Seconds

Stop wrestling with manual groupings. Simply head to your activity list, filter by date, and select exactly which tasks are ready for billing. Use the "Select All" shortcut for a specific range or pick tasks one by one for total control. Once your selection is ready, the "Create Invoice" button instantly moves everything into the high-speed batch queue for final review.

Smart Template Integration

Automated Accuracy by Default

Every project in your batch list uses its own Smart Template. Whether it's a specific tax rate for a local client or a unique currency for a global one, Chronum applies the right rules to the right invoice automatically.
