Designers / Creatives
- Fixed-price deliverables
- 2–5 clients at a time
- Need contracts and approvals
For developers
Why freelance developers need different tools.
You bill hourly. You juggle 3–10 clients simultaneously. You need to know which clients are profitable after overhead. Generic all-in-one tools were not built for how you work.
Workflow problem
Hourly billing is more complex than it looks.
Designers, consultants, and developers run different operating models. LancerOS is built around the developer one.
Consultants / Coaches
- Relationship-based work
- 5–15 clients at a time
- Need scheduling and notes
Developers (you)
- 3–10 concurrent clients
- Technical scope creep
- Need time → invoice + profitability
Generic all-in-one tools try to serve everyone. They end up serving no one well. LancerOS is built specifically for the developer workflow.
Financial intelligence
The questions you cannot answer today.
Generic tools tell you what you invoiced. They do not tell you what you actually need to know.
Effective rate
$87/hr
See which clients are actually profitable
You bill $120/hour. But after emails, meetings, and admin work, what's your real rate? LancerOS tracks billable vs overhead time per client and calculates the number your tools have always hidden from you.
Safe to spend
$3,245
Know what you can actually spend this month
Revenue minus tax reserve, minus operating costs, minus a runway buffer = what you can safely spend. LancerOS calculates this automatically so you stop eyeballing the bank account.
Revenue$12,450
Tax reserve−$3,735
Operating costs−$1,200
Runway buffer−$4,270
Safe to spend$3,245
Runway
4.1mo
Know if you have 2 months or 6 before you need to act
If all revenue stopped today, how long could you maintain current spending? LancerOS calculates months of runway at current burn rate so slow periods do not become stressful surprises.

Core workflow
Stop copying hours from Toggl to Wave.
Track time as you work. Invoice automatically at month-end. Your effective hourly rate updates in real time.
01
Track time as you work
Start a timer, select client and project, tag as billable or overhead. All hours log automatically with timestamps.
02
See real-time profitability
Effective hourly rate updates as you log hours, including the overhead most tools hide.
03
Generate invoice with one click
All billable hours auto-populate as line items. Review and send instead of copying from Toggl to Wave.
From 200+ developer conversations
What developers actually need.
01
"I need time tracking that feeds directly into invoices. Right now I track in Toggl, export CSV, manually copy hours into Wave."
02
"I want to know which clients are actually profitable — not just hourly rate, but effective rate after all the emails and scope discussions I do not bill for."
03
"I make good money but I am always anxious about whether I can spend anything because I do not know what I need for taxes or runway."
Why developer-specific matters
Built for developers. Not everyone.
By focusing on developers specifically, we could build features that actually solve your problems.

Financial dashboard Revenue and expenses only Effective hourly rate per client, safe-to-spend, runway in months, invoice aging
AI Generic prompt tools Business-context AI: profitability analysis, capacity planning, contextual client emails
Common questions
Questions developers ask.
I already use Toggl + Wave. Why should I switch? +
Time tracking → invoicing should happen automatically, not manually. LancerOS also shows you financial intelligence Toggl + Wave cannot provide: effective hourly rate per client, safe-to-spend amount, and runway in months.
What if I bill some clients hourly and others fixed-price? +
LancerOS supports both. For hourly clients, track time and generate invoices automatically. For fixed-price clients, invoice manual amounts while still tracking time for profitability analysis.
How does the effective hourly rate calculation work? +
Formula: Effective hourly rate = Total revenue from client ÷ (Billable hours + Overhead hours). LancerOS calculates this automatically as you track time.
What counts as overhead time? +
Any time you spend on a client that you do not bill for: emails, messages, project planning, scope clarification, invoicing, and admin.
Can I import from Toggl? +
Not at launch, but planned for Phase 2. For now, you can start fresh with LancerOS time tracking or maintain both systems during a transition period.
What if I have more than 10 clients? +
LancerOS supports unlimited clients on the Pro tier. With 10+ clients, the financial dashboard becomes even more valuable.
