This post is written for professionals — plumbers, electricians, locksmiths, cleaners — who are thinking about whether OSCAR is worth it financially. The platform fee is 15%. Before you do the math on whether that's acceptable, let us show you the math on what the schedule optimization actually does to your take-home. The platform fee is not the right starting point for the calculation.
Where a solo professional's day actually goes
Take a hypothetical day for a plumber managing their own bookings in Porto. First call at 08:30 in Campanhã. Finishes at 10:15. Next job: a referral in Foz do Douro. Travel time: 42 minutes at that hour, through the city centre, with parking in Foz costing 10 minutes to find. Arrives at 11:05 for an 11:00 appointment. Job done by 12:30. Lunch. Next job at 14:30 in Matosinhos — a callback from a job done last month. Travel: 35 minutes from wherever they ate lunch. Job 14:30 to 15:50. Next referral call came in during the morning — they're booked, tell the caller they'll come Thursday. End of day at 16:00 with 2.5 billable hours of travel between three jobs, and a fourth job deferred.
That pattern — three jobs, nearly three hours of overhead travel, a deferred fourth — represents a day where the professional worked from 08:30 to 16:00 with about 3 hours and 45 minutes of actual billable work. The rest was coordination overhead: travel between disconnected jobs, finding parking, managing callbacks, deferring inbound requests.
This is not an unusual day. It is a normal day for a solo professional managing their own schedule by phone and memory across Porto's geographically dispersed demand.
What clustering does to the same workday
OSCAR's scheduler builds professional days by clustering jobs geographically within half-day blocks. A plumber assigned morning jobs will typically see all three morning jobs within a 2-3km radius of each other. Travel between jobs in Bonfim, Cedofeita, and Santo Ildefonso is 8-12 minutes, not 35-42. The afternoon block similarly clusters within a zone — Paranhos and Ramalde, or Matosinhos and parts of the western coast, depending on where the demand sits that day.
The arithmetic consequence: a plumber doing 5 jobs on OSCAR with clustered scheduling might spend 45-60 minutes total in travel across the day, versus 2.5-3 hours in the uncoordinated self-managed scenario. That recovered time either becomes additional jobs — generating additional income — or it becomes genuinely finished-by-15:30 instead of finished-by-19:00-if-you-rush-the-last-job.
The 30% earnings increase figure in this article's title refers specifically to jobs-per-day improvement for professionals in our network who previously managed their own bookings. Our network data (still a relatively small sample, so we treat this as directional rather than definitive) shows that professionals moving from self-managed to OSCAR-managed scheduling typically add 1.5-2 additional jobs per working day due to reduced travel overhead. At an average job value of around €65-70 net-of-platform-fee, that is €100-140 additional daily earnings, which compounds to a significant monthly difference.
We are not claiming every professional sees exactly 30%. The number depends heavily on how geographically dispersed their previous bookings were, how many jobs per day they were already completing, and what service category they're in. A cleaning professional doing 2-3 longer jobs per day has less room for clustering gains than a plumber doing 4-6 shorter jobs. We're being honest about the variance in that claim.
The income predictability argument
Earnings improvement from clustering is one benefit. Predictability is a second benefit that professionals tell us matters as much, sometimes more.
When you manage your own bookings as an independent tradesperson, your income is variable in ways that are hard to plan around. A week with three cancellations and no replacement bookings is a bad week with no warning. A week where two clients want callbacks on jobs that turned complicated costs you two days you had allocated to new work. The income variance is structural, not exceptional.
On OSCAR, the schedule is filled before the day starts. A professional who opens the app at 07:30 sees their day already structured: three morning jobs with confirmed addresses, job type, and estimated duration; two afternoon jobs. They know by 07:30 what they will earn by 17:00. They can plan their week based on a realistic income floor, not a best-case projection.
The income floor matters for practical reasons. A professional with predictable income can service a van loan, budget for tool replacement, and make decisions about taking a week off without wondering whether that week will happen to be a bad one. These are not small things. The financial stability of self-employed tradespeople in Portugal is often more precarious than it looks from the outside, and predictable booking flow is one of the most direct levers for improving it.
The platform fee in context
OSCAR charges 15% per job. On a €65 net job (after the platform fee), the professional keeps €55.25. On a self-managed €65 job, they keep €65 — but they spent time finding that job, scheduling it, driving to it from wherever they were, and chasing payment if it was cash. The self-managed net is not €65. It is €65 minus the value of the time overhead, minus the cost of any jobs they couldn't fit in because their day was uncoordinated.
We are not saying the platform fee is trivial. 15% is a real cost, and professionals should do their own calculation based on their actual situation. What we are saying is that the fee should be evaluated against the full picture: more jobs per day, less admin overhead, predictable payment every Monday, no invoice chasing, no quote calls, no callback management. For many professionals — particularly those earlier in their career who don't yet have a full referral network — the full picture is positive. For a veteran plumber with 20 years of loyal repeat clients and zero idle travel time, the math may look different. We don't try to be the right platform for everyone.
How payment actually works
Payment from OSCAR lands every Monday for jobs completed in the previous week. No chasing, no invoice, no waiting for a client to remember to transfer the money. The job is completed, documented, and the payment processes automatically. Professionals can see their pending and completed payment ledger in the app at any time.
We don't hold float. We don't pay net-30 or net-60. Monday means Monday. That rhythm is something professionals in our network have told us — repeatedly — has changed how they think about their income. Money that you know is coming on Monday gets spent differently than money that might come sometime this month when the client gets around to it.
If there is a dispute on a job — a homeowner who raises a concern about the work — payment for that specific job is held while we resolve the dispute. We are transparent about this. The window for resolution is typically 5 business days. During that window, all other job payments continue processing normally. A dispute on one job does not freeze a professional's entire payment account.
What OSCAR is not
OSCAR is not a fit for every professional or every situation. Professionals who already have a full calendar of high-value repeat clients and no idle capacity have less to gain from our scheduling. Professionals who prefer to set their own variable hourly rates will find our fixed-price model incompatible with how they work — and we are not going to argue them out of that preference. The fixed-price model is a deliberate design choice that works well for some professionals and not for others.
We are also not a fit right now for the outer municipalities — Póvoa de Varzim, Valongo, the eastern Gondomar zones. We don't have enough demand density there to offer meaningful clustering benefits. A professional in those areas joining OSCAR today would be taking fewer bookings from a thinner network. We'd rather tell you that honestly than let you join, see a slow pipeline, and assume the problem is OSCAR's reliability rather than coverage.
If you're in Porto city or the western metro — Matosinhos, Maia's southern zones, central Gaia — and you're spending hours per day on uncoordinated travel and booking overhead, the math is probably worth looking at. That is the honest case we make.
