Comparison Table
Paymo
SMBProject management software with time tracking, expenses, estimates, and invoicing.
Approval-driven time entry submission that links directly to invoice-ready hours per project.
Paymo fits consulting practices that run client projects with recurring time entry, approval, and invoice generation cycles. The core workflow connects time tracking to projects, tasks, and billing documents so hours can move from capture to invoice output without manual rekeying. Approval routing helps keep time entry approval and invoice-ready time aligned for teams that need checks before billing.
A practical tradeoff is that Paymo’s billing outcomes depend on keeping project structure and coding consistent, because time billed is derived from how entries map to the underlying project setup. Paymo works best when teams already organize work by project and task and need predictable review steps before client invoices.
- +Project and task mapping keeps time capture aligned to invoices
- +Time entry approval workflow reduces billing rework after submission
- +Expense tracking rolls into billing documents for client-facing totals
- +Budget alerts and work-in-progress visibility support weekly project control
- –Billing depends on consistent project structure and setup choices
- –Deeper automation needs careful role design to avoid approval bottlenecks

Best for: Fits when consulting teams need task-based time capture and time entry approval before invoice-ready output.
Teamwork.com
SMBClient project management software with billable time, budgets, retainers, and invoicing integrations.
Workflow-driven time entry approvals that enforce controlled status changes tied to project work items.
Teamwork.com is built around project execution, so consultant time entries stay attached to the same work structure used for delivery tracking. The product supports timesheet-style submission and time-entry approval, plus review states for keeping billable and non-billable work distinct. Billing output is governed by project and role permissions, and the system preserves a time audit trail when entries move through approvals.
A key tradeoff is that deeper configuration and governance can be slower than lighter time-only tools, especially when approvals and billing rules vary by client. Teams that run multi-project consulting delivery use Teamwork.com to route time through approval workflows and produce invoice-ready work aligned to client task plans.
- +Task-linked time entry keeps billable effort aligned to delivery plans
- +Time-entry approval workflows support manager review and controlled edits
- +Project permissions gate who can log and adjust work by client
- +API and automation hooks support integration with accounting and internal tools
- –Approval and billing configurations can require careful rollout planning
- –Advanced billing scenarios depend on consistent project and task setup
- –Time tracking depth can feel heavier than time-only products for small teams

How to Choose the Right Consultant Time Billing Software
We separate options by how accurately they turn consultant time into billable outputs and how much control you get over exceptions. Look closely at time-entry rules, billing readiness, and audit trace quality—these determine whether your invoice drafts match how your consultants actually work.
Approval workflow for submitted time
Why it matters
Approval workflow for submitted time prevents surprises before billing. It also clarifies who can change entries after the consultant submits them.
How to check
In a demo, submit an entry in one status and ask what happens next: who receives it, how long approvals can be paused, and whether approvers can edit or only approve. Test a rejected entry and confirm whether it re-enters approval with a new revision history.
Billable vs non-billable controls
Why it matters
Billable vs non-billable controls keep reports, approvals, and invoices aligned. When your team mixes client work with internal tasks, this is where many “almost right” systems fail.
How to check
Create two activities (one billable, one non-billable) for the same day and verify how each impacts reporting and invoice selection. Ask what happens if a prior entry changes billability and whether the system recalculates invoice-ready totals.
Rounding and proration rules
Why it matters
Rounding and proration rules determine whether the system matches your contract wording and your team’s recording habits. Small differences can compound across weeks into incorrect invoices.
How to check
Look for configurable rules such as minute increments and whether rounding applies at entry-time or during billing. Run a test entry at an edge time (e.g., near a rounding boundary) and compare the stored time versus billed time shown in a sample invoice draft.
Invoice-ready draft with explanations
Why it matters
Invoice-ready draft with explanations reduces back-and-forth during billing review. You want to see how each time entry became a bill line, including what was excluded.
How to check
Generate a draft invoice for a time period and open the bill lines to trace back to source entries. Verify the draft clearly flags excluded items (wrong status, not billable, missing approval) and shows totals that reconcile with the time view.
Integration and API for time and billing
Why it matters
Integration and API for time and billing affects how reliably data moves between tools for downstream billing and reporting. The more deterministic the automation surface, the less manual rekeying we see.
How to check
Ask the vendor for an example workflow using their API or automation: create/update time entries, trigger approval, and export invoice drafts. In the demo, check whether the mapping stays consistent for recurring projects and whether you can filter by status rather than exporting everything.
Audit log for edits and approvals
Why it matters
Audit log for edits and approvals supports dispute resolution and internal compliance. When a consultant changes an entry, you need to see who changed what and when.
How to check
After approval, attempt a change to an existing time entry and confirm the system records an audit log event. Export or view the change history and verify it includes the previous value, the new value, and the user who made the change.
Red flags
- Entries change after approval without a visible audit trail
- Invoice drafts don’t show which time entries were excluded and why
- Rounding outputs billed totals that don’t match stored time in the entry view
Fit by situation
- If your process requires manager sign-off before billing, prioritize approval workflow for submitted time.
- If your consultants mix client work and internal work, prioritize billable vs non-billable controls.
- If contract wording hinges on minute handling, prioritize rounding and proration rules.
