Custom software for small businesses
Bookings, clients, finances, stock and notifications — in one app, built around the way you work. Ready in weeks, at a small-business price.
Free, no strings attached.
I built the software that runs two schools in Ericeira, from bookings to accounts. I’ll do the same for your business.
— Marcelo, founder

Sound familiar?
Bookings arrive by WhatsApp, phone and Instagram — and someone has to copy them into the diary.
Only one person understands the finance spreadsheet. When they’re off, nobody knows what came in.
You pay for four or five subscriptions that don’t talk to each other.
Closing the month with partners, commissions or affiliates takes a whole afternoon.
A client asks “is it confirmed?” and you’re not quite sure.
The software you bought makes you work its way, not yours.
It’s not that you’re disorganised. You just don’t have a tool built for your business.
What we build
Every business is different, but the building blocks repeat. We pick the ones you need and connect them.
Clients book on your website, by link or QR code. You approve with one tap and the diary updates itself.
Your whole team’s hours, shifts and tasks, with access per person: everyone sees what they need.
Install it on your home screen and get notifications. If you really need to be on the App Store, we do that too.
We connect the app to your certified invoicing software — Moloni, InvoiceXpress, Vendus and others. Invoices stay compliant.
MB WAY, Multibanco references or card, with the status of every payment in plain sight.
Automatic reminders for clients and staff, by email, SMS or phone notification.
Your clients see their bookings, payments and documents without calling you.
What came in, what’s still owed, what each partner or affiliate gets. The month closes itself.
Items, sizes and sales, with an alert when something is running low.
And also: client records with history · connections to Google Calendar, Sheets and your website · App Store and Google Play apps
Real case · Dry Waves, Ericeira
Dry Waves teaches surfskate in Ericeira, with a team of instructors and partnerships with hostels and surf camps. Lessons lived in Google Calendar, website bookings came through a plugin that didn’t talk to anything, and the month-end close — who got paid what, each partner’s share, each affiliate’s commission — was done by hand.
More work
Skate school · Ericeira
Online bookings in Portuguese and English with the liability waiver signed on the spot, class packs, end-of-day close and accounts shared by three partners — with a record of every change to the money.
iPhone app
A calendar that understands how full your day is and suggests what to do: a break, a workout, time to prepare for the big meeting. The analysis runs on the phone itself.
Desktop app
A browser with an AI assistant that only sees the pages you allow, with keys kept in the system keychain.
AI assistant
Answers legal questions based on Portuguese law and local council rules — starting with Lisbon — with deadlines, next steps and sources.
How it works
Day 1
Tell us how you work and what wastes your time. If it doesn’t make sense, we’ll say so straight away — and point you to alternatives.
Within 48 hours
What we’ll build, what it costs and when it’ll be ready. In writing, no small print.
Week 1
You tap through the main screen on your own phone before we go further. If it’s not right, we adjust.
Following weeks
Watch the app grow on a private link and give feedback every week.
Launch
We bring over what you have in spreadsheets or on paper and train your team.
After
Hosting, backups, support and improvements for one simple monthly fee.
You pay in two parts: 50% to start and 50% only once you approve the finished app.
Why it costs less than you think
Until recently, an app built from scratch cost tens of thousands of euros and months of waiting. Three things changed:
AI writes code much faster. A person designs, reviews, tests and answers for every line.
You don’t pay for account managers or endless meetings. You talk to the person who builds it.
Bookings, finances, notifications, stock: we’ve built them and use them every day. We adapt them to your business instead of starting from zero.

Ericeira · PortugalWho’s behind it
I’m Marcelo, an entrepreneur based in Ericeira.
Many small businesses run everything on Google Calendar, messages and sums done by hand at the end of the month. I build the app each one needs, shaped around how they already work, so it becomes the first thing they open every morning.
At Vektra, you talk directly to me, from the first call to the day your app goes live. And as an entrepreneur myself, I know your time doesn’t stretch to everything.

FAQ
A simple tool is ready in 2 to 4 weeks; a complete management system in 4 to 8. You see a prototype in the very first week.
From €59 a month: hosting on servers in the European Union, daily backups, security updates and support. No per-user fees — your whole team can use it.
Yes. Your data is always yours and you can export it whenever you want. If you ever stop the monthly plan, we hand over the code and help you move to other hosting.
The app uses common, well-documented technology, and the code is yours: any developer can pick it up. We also leave written instructions on how everything works.
In Portugal, invoices must come from software certified by the Tax Authority. So we connect the app to yours — Moloni, InvoiceXpress, Vendus, TOConline and others: the app asks the certified software to issue the invoice and keeps its number, ATCUD code and PDF. Some tools only open this connection on paid plans; we tell you which before we start.
Yes. It installs on your home screen like an app and gets notifications. If you really need to be on the App Store or Google Play, we do that too.
No. You explain how you work; we handle the rest and train your team.
That’s normal — businesses change. Small tweaks are covered by the monthly plan; bigger things get a quote before we start, no surprises.
We use AI to write code much faster, we don’t carry agency overhead, and we reuse building blocks that already work for other businesses. A person reviews, tests and answers for all of it.
No. We use AI to write the code, not to read your clients’ data. Your app only sends data to an AI service if you ask for a feature that needs it — and we’ll tell you exactly what.
The app stores only what it needs, on servers in the European Union, with per-person access and a record of changes. We also help you with the information you need to give your clients.
In two parts: 50% to start and 50% only once you approve the finished app. The monthly fee starts when the app goes live.
We work with businesses all over Portugal. Almost everything happens by video call; around Ericeira, Mafra and Lisbon we can also come to you.
