Capture the work.
Send a clean invoice.
A one-click timer, multi-person invoices per client, expenses billed back, and a retainer ledger that actually balances. Built so the billing side of your business stops eating your weekends.
What Track Billed Time actually does
At its core, it's a time-and-billing app: capture hours with a timer or manual entry, set per-client and per-engagement rates, and turn approved time into a professional invoice. One invoice per client, even when three teammates worked across two engagements at different rates — plus expenses billed back as line items on the same invoice.
Where it goes further than a plain timer is the rest of the day-to-day: retainer balances you need to draw from, a lightweight CRM for clients and prospects, project and deadline tracking for the team, a shared place for institutional knowledge, and — when you connect your own Stripe account — a Pay button on every invoice so clients can settle by card and the funds land in your account. All at a price that makes sense for a small or growing business.

Why generic timers and spreadsheets leak revenue
Most service businesses don't lose revenue because their rates are too low — they lose it because time captured at the end of the week is consistently under-reported. Research across professional services puts the leakage at 10–30% of billable hours. When the only "system" is a yellow pad, a Friday-afternoon calendar review, or a generic timer that doesn't know what an engagement is, the math gets worse every quarter.
The leak compounds at the billing stage. Spreadsheets can't model a rate hierarchy where one junior bills $150 on a fixed-fee engagement and $225 on hourly work for the same client. They can't show you which invoices are 60 days past due, or whether the approved courtesy discount actually got applied. Every workaround — copy-paste from a timer into an invoice template, manual rate lookups, side-spreadsheet retainer ledgers — is a place revenue quietly disappears.
Track Billed Time closes the leak end-to-end. A one-click timer that lives on every page (and shows running time in your browser tab) makes contemporaneous capture frictionless. Rates resolve automatically through an Engagement > Client > Person hierarchy. Multi-engagement, multi-person invoices consolidate into one client bill. Retainers sit next to billing so you never invoice against funds that aren't there. And AR aging plus realization tell you, in real time, what you've actually collected vs. what you billed.

Frequently asked questions
Time tracking, billing, retainers, and pricing — answered.
What is hourly time tracking and billing software?
Hourly time tracking and billing software captures billable time against specific clients and engagements, then turns those entries into accurate invoices. Unlike generic timers or spreadsheets, it handles per-engagement rates, multi-person invoices, retainer ledgers, and the review-and-approve workflow professional teams actually use.
Why do spreadsheets and generic timers leak revenue?
Time captured at the end of the week is consistently under-reported — studies show 10–30% of billable time is lost when entries aren't captured contemporaneously. Generic tools also miss the structural pieces service businesses need: rate hierarchies, approval workflows, retainer reconciliation, and aging AR. The result is leaked revenue, slower collections, and write-offs that should have been billed.
Can multiple people bill to the same client?
Yes. Every client supports unlimited team members on unlimited engagements, each with their own rate. Track Billed Time consolidates entries into a single invoice per client across every engagement and every person who touched the work — no spreadsheet stitching required.
Do you support client retainers and deposits?
Yes. Track Billed Time includes a full digital ledger for client retainers and deposits: inflows, withdrawals, low-balance alerts, and a complete audit trail. Balances are visible on the same screen as the engagement, so you never bill against funds that aren't there.
How does invoicing work for multi-engagement clients?
One invoice per client, with line items grouped by engagement. Apply per-engagement courtesy discounts, attach expenses, mark entries no-charge, and generate a clean PDF. The full lifecycle — draft, approve, send, and collect — lives in one place.
How much does Track Billed Time cost?
Per seat with volume discounts — as low as $10/user/month at scale. Time tracking, billing, retainers, and collections are all included; there is no separate billing module. See pricing for tier breakpoints.
