TimeCamp
SMBTime tracking software with automatic invoicing for billable hours.
Project-level timesheet approval workflows that gate what becomes invoice-ready time entries.
TimeCamp combines timer-based time tracking with invoicing workflows, including project assignment and billable hour handling, so teams can move from work logs to client-ready documents. It supports both manual time entry and automated time capture through timers, plus timesheet approval controls that can be enforced per project or user group.
Invoice generation centers on invoice templates and export options, with recurring invoice support for repeated engagements. Integration options tie the time records to project and accounting-adjacent workflows so invoicing stays consistent with delivery records.
- +Timer-based tracking aligns with project-based billing workflows
- +Timesheet approval controls add audit-style review before invoicing
- +Recurring invoices reduce repeated setup for ongoing retainers
- +Invoice templates keep document formatting consistent across clients
- –Invoice numbering and document controls may require stronger governance setup

How to Choose the Right Time Tracking Invoicing Software
We separate options by how they handle time capture accuracy and how they turn it into invoices: the best picks make the time-to-bill workflow predictable through configuration, data handling, and auditability. The clearest divider is whether **time entry to invoice mapping** stays correct when your work shifts by client, project, and billing rules.
Time entry to invoice mapping
Why it matters
Time entry to invoice mapping matters when your team bills across clients, projects, and rates. If the mapping is fuzzy, invoices end up tied to the wrong job or billing category.
How to check
Run a short demo workflow: enter time against multiple projects or clients, then preview the invoice and confirm each line lands where you expect. Ask what happens when you edit the underlying time after you’ve drafted or sent an invoice.
Rate and billing rules configuration
Why it matters
Rate and billing rules configuration matters because different clients use different rates and billing approaches. If the tool can’t model your rules cleanly, you’ll compensate by manual rework.
How to check
Request the product to configure at least two rate patterns (for example, different client rates or different billable/non-billable handling) and then generate an invoice preview. Check whether changes to rates update future invoices and how the tool documents the rule used for each line.
Automation and time capture options
Why it matters
Automation and time capture options matter when teams want fewer steps and fewer transcription errors. The goal isn’t “more automation”; it’s keeping time capture consistent with your invoice outcome.
How to check
Ask the demo to show both a quick capture path and a corrective path for missed entries. Then test whether those entries appear in the next invoice draft without extra manual transformations.
Invoice draft controls
Why it matters
Invoice draft controls matter because real work changes before you finalize billing. If the tool lacks guardrails, people can send incorrect invoices or duplicate effort.
How to check
In the demo, create a draft invoice, then adjust one time entry and observe what updates (line items, totals, and descriptions). Ask whether drafts can be locked or require explicit review steps before sending.
Audit log and edit history
Why it matters
Audit log and edit history matters when billing disputes or internal reviews happen. You need a clear trail of what changed, by whom, and when—without guessing.
How to check
In the demo, modify a time entry after the invoice draft exists and then open the invoice and time record history. Ask whether the system preserves an audit log that shows the before/after values.
Exports that preserve invoice meaning
Why it matters
Exports that preserve invoice meaning matter if you reconcile in another system or share with accounting. If exports lose key mappings, totals won’t match what clients see.
How to check
Generate an invoice in the tool and then export it in the format you’d actually use. Verify that exported line items still match the original mapping, totals, and descriptions from the invoice preview.
Red flags
- Invoice previews don’t match what time entries map to
- Rate rules require manual edits after time entry changes
- Edits after draft aren’t traceable in an audit log
Fit by situation
- If you bill by shifting projects across clients in the same week, prioritize time entry to invoice mapping.
- If your clients use multiple rate patterns, prioritize Rate and billing rules configuration.
- If you expect billing disputes or frequent corrections, prioritize Audit log and edit history.
