DoubleTime helps freelancers, consultants, developers, trade professionals, and other solo professionals keep client work, rates, and invoices connected.
Instead of acting like a generic timer, DoubleTime is built around the billing workflow: capture billable work, assign it to a client or project, apply saved rates, review what is ready or blocked, then turn it into a clean invoice.
Use DoubleTime to record calls, fixes, notes, follow-ups, and project work as they happen, or add manual line items later when work was not captured at the time. The Billing Hub helps show work that is ready to invoice, entries that need a client or rate, sent invoices, and overdue balances.
DoubleTime includes client and project management, saved rates, invoice creation, invoice sending, tax controls, unbilled work reports, overdue invoice reports, and a PWA experience that works across desktop, mobile, and web.
It is designed for solo professionals who want fewer billing gaps, clearer records, and a faster path from client work to paid invoice.
Unleashed Software DoubleTimeUnleashed Software is recommended for medium to large-sized businesses that need detailed inventory tracking and management. It's especially suited for those in the manufacturing, distribution, and retail sectors who require seamless integration with accounting and eCommerce systems. Companies looking for scalability and advanced reporting capabilities may also find Unleashed Software particularly beneficial.

DoubleTime's answer:
DoubleTime started from a simple problem: client work often happens in small scattered moments, but invoicing usually happens later.
By the time a freelancer or contractor sits down to invoice, they may be trying to reconstruct what was done, who it was for, whether it was billable, and what rate should apply. That creates billing gaps, delayed invoices, and uncertainty.
DoubleTime was built to keep those pieces connected. Capture the work, apply the right client and rate, review what is ready or blocked, then create the invoice without piecing everything together from memory.
DoubleTime's answer:
Choose DoubleTime if your main problem is not just tracking time, but turning client work into invoices with less guesswork.
DoubleTime is designed for solo billers who want to keep clients, rates, captured work, invoice items, and billing status in one place. It helps show what is ready to invoice, what needs attention, and where billable value may be sitting unbilled.
It is simpler than a full accounting platform, more billing-focused than a generic task manager, and more outcome-focused than a timer alone.
DoubleTime's answer:
DoubleTime connects the work capture and invoicing process instead of treating them as separate jobs.
Many time trackers stop once work has been recorded. DoubleTime goes further by helping users understand what that work is worth, whether it is ready to invoice, what still needs attention, and which invoices are sent, paid, or overdue.
It also supports manual invoice items, so users do not have to track every minute to use the product. They can capture work as they go or add billable items later when needed.
DoubleTime's answer:
DoubleTime is built for solo professionals who bill clients for their work, including freelancers, consultants, developers, designers, trade professionals, and other independent service providers.
It is especially useful for people who deal with scattered billable work: calls, fixes, revisions, notes, follow-ups, support tasks, and project work that can be easy to forget by invoice time.
DoubleTime is not aimed at enterprise workforce monitoring. It is for people who need a clearer path from client work to invoice.
DoubleTime's answer:
DoubleTime is built as a modern Progressive Web App, allowing it to run in the browser and be installed across desktop and mobile devices.
The PWA approach helps keep the product accessible without forcing users into a platform-specific app store. It also supports the way solo professionals actually work: capturing billable items from different devices, then reviewing clients, rates, invoices, and reports from one place.
