ProblemThe problem
Pet perionica, pet blagajni i gomila troškova koji su se plaćali na različitim mestima. Vlasnik nije znao tačno šta plaća, gde i kako, niti koliko je novca stiglo karticama, a koliko kovanicama i žetonima. Najveći problem: za to da je vosak, šampon ili aktivna pena potrošen saznavao je tek kad bi rezervoar već bio prazan — a boks bez hemije je boks koji ne zarađuje.Five car washes, five cash boxes and a pile of expenses paid in different places. The owner didn't know exactly what he was paying, where or how, or how much money came in by card versus coins and tokens. The biggest problem: he only found out that wax, shampoo or active foam had run out once the tank was already empty — and a bay without chemicals is a bay that earns nothing.
RešenjeThe solution
Jedna aplikacija za svih pet lokacija, napravljena prvo za telefon. Pregled pokazuje prihod za danas, juče, 7 dana ili ceo mesec, po perionici, i tačno koliko je stiglo kovanicama, žetonima i karticom. Odmah ispod stoji lista „Treba reagovati”: koja perionica ostaje bez pene, šampona ili voska i gde je menjač kovanica skoro pun. Svaka perionica ima i svoj detaljan prikaz — prihod po boksu, korišćeni programi, dnevna potrošnja i stanje svakog uređaja. Pristup je zaštićen prijavom — svaki korisnik ima svoj nalog, a svi podaci se čuvaju u PostgreSQL bazi na Render-u.One app for all five locations, built phone-first. The overview shows earnings for today, yesterday, 7 days or the whole month, per car wash, and exactly how much came in by coins, tokens and card. Right below sits a “Needs attention” list: which car wash is running low on foam, shampoo or wax, and where the coin changer is almost full. Every car wash also has its own detailed view — earnings per bay, programs used, daily consumption and the state of every device. Access is protected by login — every user has their own account, and all data lives in a PostgreSQL database hosted on Render.
Materijal i troškoviMaterial and expenses
Ekran Materijal pokazuje koliko je čega potrošeno i koliko je koštalo, koliko je pun svaki rezervoar u svakoj perionici i šta ima u magacinu — sa procenom za koliko dana je dovoljno. Sve ispod 25% je označeno da se dopuni u narednih dan-dva. U Troškovima se svaki novi trošak upiše za tačnu perionicu i kategoriju, a trošak materijala se računa automatski, pa se na kraju meseca tačno zna gde je novac otišao.The Material screen shows how much of each product was used and what it cost, how full every tank is at every car wash, and what's in the storage — with an estimate of how many days it will last. Anything under 25% is flagged to be topped up within a day or two. In Expenses, every new cost is entered for the exact car wash and category, and material costs are calculated automatically, so at the end of the month it's clear exactly where the money went.

RezultatThe result
Vlasnik sada ima jasnu sliku svih pet perionica na jednom ekranu: koliko je zaradio i na koji način, koliko troši i na šta. Upozorenje stiže pre nego što se nešto potroši, a ne kad je već kasno — pa je uvek spreman za svaki scenario.The owner now has a clear picture of all five car washes on one screen: how much he earned and how, how much he spends and on what. The alert comes before something runs out, not when it's already too late — so he's always ready for any scenario.
