Comparison Table
Toggl Track
SMBTime tracking tool with invoicing capabilities for billable hours.
API-driven timesheet retrieval and webhook events enable invoice handoff automation.
Toggl Track pairs manual entry with stopwatch capture so teams can handle both round-trip timesheet entry and quick start sessions in the same workspace. Timesheet data maps cleanly to clients and projects, which helps create consistent totals for invoice line items and project budget variance checks. The API and webhook options support integration depth for tools that need to read timesheets, then trigger invoice delivery. Governance is workable with organization-level settings and role-based access, but it is not aimed at enterprise DCAA compliance mode controls for regulated contracting.
A tradeoff appears when invoice computation requires heavy custom rules like write-up and write-down tracking per line item, because invoice logic relies more on exports and external invoicing layers. Toggl Track works well for service firms that bill by project and need fast corrections, such as updating a week after a field visit.
- +Stopwatch and manual entry workflows for consistent round-trip edits
- +Tags and client-project structure that maps well to invoice totals
- +API and webhooks for automating timesheet sync and invoice handoff
- +CSV timesheet import supports migration and correction cycles
- –Invoice rule complexity is limited for tiered markups and adjustments
- –Approval-chain routing depends on workspace configuration
- –Approval and audit detail is less granular than DCAA compliance mode requirements
- –Advanced invoice templating needs integration with invoicing tooling

How to Choose the Right Time Tracking Invoice Software
We separate options by how accurately they handle the path from work capture to documents, and how well they control billing details in one workflow. The biggest differences usually show up in invoicing automation, timesheet approval workflow, and audit log strength.
Invoice generation rules
Why it matters
Invoice generation rules decide whether a timesheet turns into the right invoice lines without manual cleanup. If rules are thin, you spend time fixing formatting, rates, and billing labels after export.
How to check
On a demo, create one project with billable and non-billable time and generate an invoice from the same time entries. Verify the invoice shows the expected line items, dates, and billing units, and confirm what happens if you edit a timesheet after invoicing.
Timesheet approval workflow
Why it matters
A clear timesheet approval workflow prevents incorrect billing and reduces back-and-forth between submitters and approvers. It also shows how the system enforces who can change what and when.
How to check
Ask for a scenario with at least two roles: submitter and approver. Try submitting timesheets, approving them, then attempt edits afterward; confirm what is blocked and what requires re-approval.
Rate and billing configuration
Why it matters
Rate and billing configuration matters because time tracking invoice software must keep client rates consistent across projects. Poor configuration leads to wrong amounts, inconsistent units, and messy adjustments.
How to check
Set different rates for two clients (or two projects) and include overlapping work days. Generate invoices and confirm the system consistently applies the correct rate, billing unit, and tax fields on every invoice line.
Invoice data export and import
Why it matters
Export and import quality affects whether you can move data between your workflow tools without losing mapping. If formats are brittle, reconciliation becomes a recurring job.
How to check
Export invoices and time entries in the product’s supported formats. Then import the same dataset into a test instance (or simulate by re-uploading) and check whether project, dates, and billed units remain intact.
Invoice editing and versioning
Why it matters
Invoice editing and versioning determines whether corrections stay traceable and whether the system preserves the history of changes. For billing work, that history is often the difference between a quick fix and a dispute.
How to check
Generate an invoice, make a small change to the underlying time, and regenerate or revise the invoice. Confirm what the system keeps (old values, change reason fields, and whether a new invoice is created) and whether links back to the source time remain visible.
Audit log for billing changes
Why it matters
An audit log for billing changes helps you answer “who changed what” during reviews and client questions. Without it, you rely on email threads and spreadsheets to reconstruct facts.
How to check
On a demo, perform a timesheet approval, then edit a time entry, and regenerate an invoice. Open the audit history and confirm it records the actor, timestamp, and the specific billing-relevant change.
Red flags
- Invoices don’t clearly reflect which approved time produced each line
- Approvals can be bypassed or edits after approval don’t show traceable effects
- Exports scramble dates, units, or project links so reconciliation takes manual work
Fit by situation
- If you need approvals before anything becomes billable, prioritize timesheet approval workflow.
- If different clients have different rates and billing units, prioritize rate and billing configuration.
- If your billing team must correct invoices while preserving history, prioritize audit log for billing changes.
