If you are searching for a Harvest alternative because you want better time tracking, Sengi is not what you need. If you are searching because you track hours in Harvest but still do not know whether your projects are profitable, Sengi solves that problem. Harvest and Sengi measure different things.
Harvest is a time tracking and invoicing tool. It records how many hours you spend on projects, generates invoices from time entries, and produces utilization reports. It was built for teams and agencies who bill by the hour. Sengi does not replace Harvest for granular time tracking or team management.
Sengi is a profitability tracking tool for solo freelancers. It calculates your effective hourly rate by dividing your project fee by the hours you actually worked, showing you what each hour of effort earned rather than just counting how many hours you spent.
The difference sounds subtle. It is not. Harvest answers “how many hours did I work?” Sengi answers “what did those hours earn me?”
Why Harvest cannot show your effective hourly rate on flat-fee projects
Harvest was designed for hourly billing. The core workflow is: log hours, set a billing rate, generate an invoice for hours multiplied by rate. This works perfectly when the client pays by the hour.
Most freelancers do not bill by the hour. Designers, consultants, copywriters, and web developers typically charge flat project fees, retainers, or value-based pricing. On these projects, Harvest's billing rate field is disconnected from reality. You can set it to $150/hr, but if the project fee was $5,000 and you worked 55 hours, your effective hourly rate was $91, not $150. Harvest has no mechanism to calculate this, because its architecture assumes hours multiplied by rate equals revenue. On flat-fee projects, that equation does not hold.
You could theoretically enter your flat fee and divide it manually by your logged hours. But Harvest does not do this calculation for you, does not track it across projects, does not alert you when it drops below your target, and does not detect scope creep patterns. These are the functions that define profitability tracking, and they are outside Harvest's design.

| What you need to know | Harvest | Sengi |
|---|---|---|
| Hours logged per project | Yes (detailed) | Yes (project-level) |
| Effective hourly rate per project | No (only billing rate) | Yes (real-time, based on actual fee) |
| Budget tracking by hours | Yes | Yes (with alerts at 80% and 100%) |
| Scope creep detection | No | Yes (automatic) |
| Utilization rate | Yes | No (not relevant for solo freelancers) |
| Team timesheets and approvals | Yes | No (built for solo) |
| Invoice from time entries | Yes | No (invoices based on project fees) |
| Profitability ranking across projects | No | Yes |
| Designed for solo freelancers | No (team-first) | Yes |
The question behind “Harvest alternative”
Freelancers searching for Harvest alternatives typically have one of two frustrations:
“I want simpler time tracking without team features I do not use.” If this is you, Toggl Track, Clockify, or a simple timer app might be better fits. Sengi is not a time tracking tool with fewer features.
“I track hours in Harvest but I still do not know if my projects are profitable.”If this is you, the problem is not Harvest's time tracking. It is that time tracking alone cannot tell you profitability. You need a tool that connects your fees to your hours and calculates the effective hourly rate automatically. This is what Sengi does.
The second frustration is common among freelancers who charge flat fees. They diligently log hours in Harvest, see reports showing 45 hours on Project A and 30 hours on Project B, but cannot answer the simple question: which project paid better per hour? Harvest shows the input (hours). Sengi shows the output (effective hourly rate).
What Harvest is genuinely good at
Harvest is a mature, well-designed time tracking tool. Its strengths are real:
- Detailed time logging with project and task breakdowns
- Team timesheets with approval workflows
- Client-facing reports for hourly billing transparency
- Budget tracking by hours (though without fee-based alerts)
- Integration with project management tools (Asana, Trello, Basecamp)
- Expense tracking tied to projects
If you lead a team of contractors who bill by the hour, Harvest is purpose-built for you. The mismatch appears only when solo freelancers charging flat fees try to extract profitability insights from a tool designed for agency-style hourly billing.
Why Sengi does not replace Harvest (and approaches the problem differently)
Sengi does not try to be a better time tracker. It is a different category of tool. Where Harvest asks “how are you spending your time?” Sengi asks “is the time you are spending earning enough?”
Sengi's effort tracking is deliberately simpler than Harvest's. You log total hours per project at the end of a work session or week, not per-minute entries with task breakdowns. This is by design: for calculating effective hourly rate, you need accurate total hours, not granular task-level data. The simplicity makes it sustainable for solo freelancers who do not have the time (or the need) for detailed timesheets.
If you need both granular time data and profitability tracking, you could use Harvest for time logging and Sengi for the profitability layer. But most solo freelancers find that Sengi's built-in effort logging gives them everything they need without the overhead of a separate time tracker.
Sengi vs Harvest: FAQ
Is Sengi a replacement for Harvest?
Not directly. Harvest is a detailed time tracker built for teams who bill by the hour. Sengi is a profitability tracker built for solo freelancers who charge flat fees. If you need team timesheets and hourly billing, Harvest is the right tool. If you need to know your effective hourly rate per project, Sengi is the right tool.
Can Harvest calculate my effective hourly rate?
No. Harvest tracks hours and applies a billing rate, but it does not divide your flat project fee by actual hours worked to produce an effective hourly rate. On flat-fee projects, Harvest cannot tell you what each hour of work actually earned.
Why is time tracking not enough for freelancer profitability?
Time tracking measures input (hours spent). Profitability requires connecting input to output (what those hours earned). A time tracker that shows 45 hours on a project tells you how busy you were, not whether the project was worth your time. For that, you need to divide the fee by the hours, which is what effective hourly rate tracking does. For more on this distinction, see Time Tracking vs Profitability Tracking.
Does Sengi track time?
Yes, but differently than Harvest. Sengi's effort tracking is designed for calculating effective hourly rate, not for generating hourly invoices. You log total hours per project session rather than starting and stopping a timer for each task. This is simpler and takes less effort to maintain.
Do I need both Harvest and Sengi?
Most solo freelancers do not. If you charge flat fees and your primary need is understanding project profitability, Sengi's built-in effort tracking is sufficient. If you need detailed, per-task time logs for client reporting or internal analysis, you could use Harvest for time data and Sengi for the profitability layer that Harvest cannot provide.
How much does Sengi cost compared to Harvest?
Sengi is $29/month (Starter) or $49/month (Pro). Harvest is free for 1 project and approximately $10.80/user/month for unlimited. Since they serve different purposes, the comparison is whether profitability visibility is worth the cost. If knowing your effective hourly rate helps you reprice one underperforming client per quarter, the investment pays for itself.
