How many hours a week do you spend copying data from one place to another?
Custom tools for businesses losing hours to repeated tasks.
Bookings that land in your calendar, a CRM with your clients on a map, a panel to publish without asking anyone. We design and build them around the way you work, connected to your website and to what you already use.
Generic tools make you work their way.
Many businesses live between a marketplace that owns the customer relationship, several Excel sheets and a WhatsApp that never stops. Each tool solves a piece, nobody connects them, and time goes on copying data from one place to another.
A custom tool does only what your business needs, with your steps and your names, and connects to what you already use: Google Calendar, Google Sheets, WhatsApp or your website. Jowel left Treatwell for his own booking system; Fincas Castro publishes its flats and works its area with a CRM built for its team.
What we can build
Online bookings
Appointments per service with their real duration, landing in your Google Calendar and copied to a sheet. Like Jowel Barber Studio's system.
Custom CRM
Your clients, buildings or projects with their history, on a map if needed and with roles for each team member. Like Fincas Castro's.
Publishing panels
Listings, products, menus or events the team uploads from their phone and that appear on the site straight away.
Automations
Forms that reach WhatsApp already written, renewal reminders, copies into spreadsheets: let the system do the repetitive work.
Team apps
Tools that install on Android, iPhone and desktop, with sign-in through each person's Google account.
Connected to your site
The tool feeds the site and the site feeds the tool: part of the same online presence.
It all starts with a diagnosis.
Before doing anything, Guevara Web OS analyses your online presence and ranks the improvements by impact.
How Guevara Web OS worksHow we work
We see how you work
Before proposing anything we look at your day: what you do by hand, what repeats and where customers or data get lost.
Fixed proposal
What the tool will do, price and timeline in writing before we start.
Essentials first
A first version running on your real data; then we refine it with your team.
Maintenance and improvements
A living tool: we adjust it when the way you work changes.
Frequently asked questions
Why not use an existing tool?
If an off-the-shelf tool works for you, we'll say so. We build custom when generic ones make you pay for what you don't use or work their way.
How much does it cost?
It depends on what it has to do. It usually sits within a Bespoke project, from €3,000, or is quoted separately. You get a fixed price before we start.
Where does my data live?
In exportable services such as Google Calendar, Google Sheets or a server. Before we start we explain where each piece of data lives and who has access.
Does it work on mobile?
Yes. We design mobile first and, if needed, it installs as an app.
