AI, automations and custom software

The exact piece where your business and technology fit together: from your web presence to native ERP/CRM systems and AI integrations. I build them myself, end to end, here in Lloret de Mar.

No cost, no strings attached. I look at your business before the call, so I am not coming to ask what you need: I come with what I have already seen. Two slots a week.

The Fitting Piece

The Teselar visual identity is inspired by tessellation: the art of assembling pieces so they fit together perfectly, leaving no gaps and creating no friction.

In the digital world, Teselar is that exact piece of custom software that your business needs to complete its gears and run with total fluidity.

Why TESELAR?

Why Work With Me?

The competitive advantage of working with specialized software craftsmen instead of slow corporate agencies or unstable freelancers.

Direct Contact, No Intermediaries

I speak your language. You deal directly with the developer writing every line of your software, with no delays and no misunderstandings.

Custom Native Development

I avoid heavy, slow, and insecure WordPress templates. I hand-craft websites using React and Tailwind, which gives you unrivaled speed and outstanding SEO.

Local Proximity & Understanding

Based in Lloret de Mar. I like getting to know your business up close, meeting in person, and designing the solution that fits your local goals.

Three services talk over WhatsApp, and they are not the same thing

Guided chatbot · part of 02

Follows a script of buttons and pre-written answers. Cheap and enough when the questions are always the same; step off the script and it gets stuck.

AI assistant · service 05

Understands plain wording and answers with your business information. It informs and guides, but it does not touch your calendar. It is built from scratch around your documentation, your channels and your systems, which is why the range is wide. It is what you are using here: TesS.

WhatsApp Booking · service 03

An AI assistant that also acts: it checks the slots you actually have free, books the appointment, confirms it and sends the reminder. It is already built and proven — it gets configured with your services and opening hours, which is why it costs less than bespoke work and can carry a guarantee.

The question to choose is simple: are you losing unanswered enquiries, or uncaught bookings? And if it is bookings, do not pay for bespoke work: that one is already built and costs you less.

Processes and costs

01. Process Audit

Ideal for:Businesses that suspect they are losing time or money in their day-to-day operations and want to know where, in writing, before investing. It is the second step when what you need is custom-built: the way in is the free 30-minute diagnosis, and if what comes out of it is a closed product —WhatsApp appointments, a simple website or a small automation— you go straight to the proposal, with no audit. These 150€ are deducted if you accept the proposal within the following 30 days.
What is included:
  • 60-90 minute session going through your operations with your own figures in front of us. Beforehand I tell you what to bring, which is not much and depends on your business
  • Mapping of up to three processes: who does what, when, and with which tool
  • Where waiting, errors, or repeated work are created
  • Your numbers: how many times you do a task, how long it takes and what it costs you
  • What can be automated, what cannot, and in what order
  • A written 2-3 page report with priorities, and with it the proposal with the price of what would come out of it: you decide whether to accept it. If I see nothing worth your while, I tell you so and there is no proposal
  • The digital pre-diagnosis of your website and social media, included
Price150€ (Deducted from your first project) + VAT
Apps Script + APIs + Make

02. Specific Automations

Ideal for:Companies with one specific repetitive task to get off their plate: a process someone does by hand today, every week, always the same way.
What is included:
  • Automatic generation of PDF quotes/budgets from a web form
  • Automatic invoice mailing connecting directly with your CRM
  • Automated data extraction from emails directly into Google Sheets
  • Guided-reply chatbots for WhatsApp or Telegram (they follow a script; if you need it to understand free language, that is AI Integration)
  • Two-way database synchronization between different platforms
  • Smart automated alert and notification system
  • Daily or weekly automated email reporting
  • Basic maintenance plan (60€/mo), required while the automation is running: I keep an eye on it and fix it when an API changes or a credential expires. Where my work ends: it does not cover new features, process changes, or wiring in tools that were not part of the agreed scope — those are quoted separately
Price700€ — 1,800€ + 60€/mo + VAT
WhatsApp Cloud API + Calendar

03. WhatsApp Appointment Booking

Ideal for:Appointment-based businesses still booking by hand: hair and barber shops, beauty salons, physiotherapy, clinics, workshops or consultancies.
What is included:
  • An assistant answers your WhatsApp around the clock: checks open slots, books the appointment and confirms it without you replying
  • Synced with the calendar you already use — never two bookings in the same slot
  • Automatic reminder before the appointment, which is what keeps people from missing it
  • Reschedules and cancellations over the same WhatsApp, no calls and no dead slots
  • Dashboard with your bookings and a counter of those that came in outside your opening hours
  • Guarantee: if not a single booking comes in outside your hours in the first three months, you get the setup fee back
  • Automatic Google review request once the appointment is over, as an add-on (+200€)
  • There is a version without the WhatsApp API for 400€-700€ + 90€/month, and it is not the same thing cheaper: there is no assistant holding a conversation — your client writes to your usual WhatsApp, gets a link and books on a page, and the confirmation and reminder arrive by email or SMS. In exchange you do not migrate your number or depend on Meta
Price700€ — 1,800€ + 150-250€/mo + VAT
React + Vite + Tailwind CSS

04. Essential Web

Ideal for:Freelancers, small businesses, independent professionals, and new entrepreneurs.
What is included:
  • High-impact single landing page or 3-4 structured sections
  • Modern, responsive, and mobile-first web design
  • Functional contact form and WhatsApp button with automated notification
  • 1 language included — each additional language +150€
  • Basic technical SEO (optimized meta tags, clean HTML structure)
  • Extreme load speed and performance optimization
  • 1 week of live adjustments during deployment
Price1,200€ — 1,600€ + VAT
OpenAI / Anthropic APIs

05. Artificial Intelligence Integration

Ideal for:Businesses fielding the same questions over and over by hand: opening hours, prices, how something works, whether you offer a given service. The assistant answers for you using your business information, but it does not manage your calendar — if what you are losing is bookings, the service you want is 03. Final price depends on complexity: a simple single-channel chatbot sits at the low end of the range; an advanced assistant with multiple integrations and channels (web, WhatsApp, Telegram) sits at the high end.
What is included:
  • Custom virtual AI assistant trained with your internal company documentation
  • Smart customer service chatbot for web, WhatsApp, or Telegram: it informs and guides using your data, without managing your calendar (that is what WhatsApp Booking is for)
  • Automated generation of text content or custom email templates
  • Automated analysis, classification, and summary of documents
  • Advanced automation using Natural Language Processing (NLP)
  • Direct integration with models like GPT-4, Claude 3.5, and others
  • Monthly assistant fee, required, in three tiers: 90€/mo for a single channel, 150€/mo for several channels or with integrations, and 250€/mo when it is multichannel and also wired into your systems. It covers reviewing the conversations, correcting whatever gets answered wrong, and keeping the information it answers with up to date. AI API usage is billed to your own account, in your name
Price1,600€ — 6,000€ + 90-250€/mo + VAT
React + Vite + Headless CMS

06. Complete Web

Ideal for:SMEs that need their business's real website: catalog or portfolio, blog, and ready for foreign customers.
What is included:
  • Includes everything in the Essential Website (04): 3-4 sections, responsive design, contact form and WhatsApp button, basic SEO and 1 week of live adjustments

  • Project gallery or interactive portfolio with dynamic filters

  • 1 week of live support and comprehensive training included
PriceFrom 3,000€ (2 languages included) + VAT
React + DB + Payment Gateways

  • Interactive, fluid, and ultra-fast loading shopping cart
  • Secure and simplified one-step checkout process
  • Full integration with Stripe, PayPal, and credit cards

  • 2 languages included for foreign buyers — each additional +250€

  • Per-property contact form and WhatsApp button
  • Local SEO, and maintenance included for the first year (portal feeds need monitoring)

What is included:
  • Self-installing native desktop application (Windows, macOS, Linux)
  • Interactive dashboard with financial charts and live metrics
  • Complete client management (CRM) and contact database module

  • Basic maintenance plan included for the first year; after that, 60€/mo with no lock-in
Price8,000€ — 12,000€ + VAT
What is NOT included

Third-party costs paid by the client — though I handle the setup for you: domain and hosting, payment gateway fees (Stripe/PayPal), business email, email marketing tools, and AI API usage. Also not included: copywriting and photography (provided by the client; AI-assisted copywriting available as an extra), professional or sworn human translation (reviewed AI translation IS included with contracted languages), paid advertising (Google/Meta Ads), social media management, and new features outside the agreed scope, which are quoted separately. For the WhatsApp Booking product, the messages WhatsApp sends are not included either: from 1 October 2026 Meta charges for them (between 1.7 and 3.3 cents per booking, worked out from its official rates) and bills you directly, because the WhatsApp account is yours; what your clients write is always free. The cost of the AI model IS included in the monthly fee, for normal business use (up to 500 conversations a month on the Essential plan and 1,500 on the Complete one).

Payment Terms & Methods

Methods: Accepted methods: Bank transfer or cash in hand (by appointment).

Terms: A 10% deposit (minimum 150€) is all that is needed to start. The rest is split interest-free into 3 or 4 instalments, and each one is paid against a delivery —the design, the working core, the deployment and the acceptance—, not against a calendar date. And if you have already paid for the Process Audit, those 150€ are already paid and come off the deposit. All prices are + VAT.

I work with a limited number of clients so I can look after every project properly.

  • Same business day response (4h for critical issues) and monthly report
WhatsApp Booking · service fee
150€ — 250€/ month + VAT

The WhatsApp Appointment Booking product carries its own fee, separate from maintenance: 150€/month for the Essential plan and 250€/month for the Complete one. It is not an optional add-on, it is the service running. The Essential plan has one calendar, one appointment at a time; the Complete one handles several at once, for when two or more people are seeing clients at the same time.

  • The assistant answering your WhatsApp every day, supervised and corrected whenever something changes — with the AI model cost included: no signing up to any AI service and no API keys to manage
  • Changes to opening hours, services, prices and wording whenever you need them
  • The messages WhatsApp sends are billed by Meta straight to your own account: between 1.7 and 3.3 cents per booking, worked out from Meta's official rates in force since 1 October 2026. The assistant's replies fall within the 1,000 free messages a month Meta gives each number, which cover up to about 250 bookings a month; what you pay for is the reminder and the confirmation. What your clients write is always free

AI Integration · assistant fee
90€ — 250€/ month + VAT

An AI assistant is not something you hand over and forget: it needs looking at every month, and the more that was built, the more there is to watch. Three tiers: 90€/month for a single channel, 150€/month for several channels or with integrations, and 250€/month when it is multichannel and wired into your systems. It is separate from website maintenance, just like the booking product fee.

  • I review the conversations and fix anything answered wrongly or halfway
  • I keep the information it answers with up to date: prices, services, opening hours and copy
  • Here the AI API usage is paid by you, in your own account and in your name — unlike the Booking product, where it is included in the fee

FAQ

Frequently Asked Questions

What people ask me most before starting a project. Got another question? Just write to me.

It depends on scope: an Essential Website (single page or 3-4 sections) costs 1,200€-1,600€, and a Complete Website (blog, admin panel, portfolio) starts at 3,000€. Both include 1 week of live adjustments after launch. I give you a closed price after the first conversation, no surprises.

I am based in Lloret de Mar and serve the whole Costa Brava area in person (Blanes, Tossa de Mar, Girona), but I work remotely with clients anywhere in Spain without any issue.

Yes, it is one of my specialties: Real Estate Websites from 6,000€, with a property search engine with filters, a management panel with no coding required, and XML export in Kyero format to automatically sync with Idealista, Habitaclia, and Fotocasa.

Yes — in fact the TesS assistant you can chat with right now on this site is the live demo of that exact service. AI Integration costs between 1,600€ and 6,000€ plus the assistant fee (90€/month for a single channel, 150€/month for several channels or with integrations, and 250€/month when it is multichannel and wired into your systems), depending on that same complexity; the API keys stay under your own account, no middlemen.

I communicate and work in Spanish, Catalan, and English, but your project can be delivered in any language you need thanks to AI-assisted translation — I am not limited to those three. The Essential Website includes 1 language (+150€ per extra language), and the Complete Website and Real Estate Website include 2 languages (+250€ per extra one). Reviewed AI translation is included; professional or sworn human translation is billed separately.

Two no-lock-in plans: Basic (60€/month) includes 24/7 monitoring, weekly backups, updates, 1h/month of changes, and a quarterly report. Plus (150€/month) adds daily backups, 5h/month of development, payment gateway and portal feed monitoring, same-day response, and a monthly report. Separately from maintenance there are two fees of their own, because they are running services rather than a watched website: the AI Integration assistant (90-250€/month) and WhatsApp Booking (150-250€/month). And Specific Automations include the Basic Plan as a requirement while they are running, because an unwatched automation breaks silently the day an API changes.

A 10% deposit to start, with a minimum of 150€, and the rest in 3 or 4 interest-free instalments. What matters: each instalment is paid against a delivery —the design and scope, the working core, the deployment and the acceptance—, not against a date. So you never pay in advance for work you have not seen. And if you already paid for the Process Audit, those 150€ come off the deposit: on an 8,000€ project the deposit is 800€, so you would pay 650€. I accept bank transfer or cash in hand by appointment.

It is a 60-90 minute session going through your operations with you and your own figures in front of us —beforehand I tell you what to bring, which is not much and depends on your business—, plus a written 2-3 page report: which processes are costing you time or money, how much, and what can be automated and in what order. With the report I send you the proposal with the price of what would come out of it, and you decide whether to accept it; if I see nothing worth your while, I tell you so and there is no proposal. It costs 150€, deducted from the project if you accept the proposal within the following 30 days. It also includes the digital pre-diagnosis of your website and social media. Before the audit there is the free 30-minute diagnosis: if for now you only want the conversation, you do not have to pay anything.

Third-party costs are billed to the client, even though I handle the setup: domain, hosting, payment gateway fees, business email, and AI API usage. It also does not include copywriting/photography (provided by the client), sworn translation, paid advertising, or social media management. In the WhatsApp Booking product the messages WhatsApp sends are not included either: from 1 October 2026 Meta charges for them and bills you directly, because the account is yours — between 1.7 and 3.3 cents per booking, worked out from Meta's official rates. What the fee does include is the cost of the AI model, for normal business use.

Yes, it is one of my services. An assistant answers your WhatsApp around the clock: it checks the open slots in your calendar, books the appointment, confirms it and sends the reminder, with no need for you to reply. The Essential plan is 700€-900€ to set up plus 150€/month, for one calendar with one appointment at a time, and the Complete one 1,500€-1,800€ plus 250€/month, for when several people see clients at the same time. All + VAT. It comes with a guarantee: if not a single booking comes in outside your opening hours during the first three months, you get the setup fee back. You need the number on the WhatsApp Business app (migrating is free, takes ten minutes and I help you do it). Linking your number to the system depends on an approval from Meta: I do not control that timeline, and I give it to you in writing in the proposal. If you would rather not depend on Meta there is a version without the API for 400€-700€ plus 90€/month, but be clear that it is not the same thing cheaper: there is no assistant holding a conversation. Your client writes to your usual WhatsApp, gets a link and closes the booking on a reservation page, and the confirmation and reminder arrive by email or SMS, not by WhatsApp. In exchange you do not migrate your number, you do not depend on Meta's timelines and you pay no messages.

They look alike from the outside and do very different things inside, so it is worth clearing up before you pay for something you do not need. A guided-reply chatbot (part of Specific Automations) follows a script: buttons and pre-written answers, and the moment someone asks something that was not scripted, it gets stuck. An AI assistant, like TesS —the one you are chatting with on this site—, understands what people write in plain words and answers with your business information: it informs, guides and captures the contact, but it does not touch anything inside. And the WhatsApp Booking system is an AI assistant that also acts: it looks at the slots you actually have free in your calendar, books the appointment, confirms it and sends the reminder. That is the difference that matters: the first two tell people things, the third one does the work. That is why only the booking product carries a guarantee, its own fee and the AI model cost included, while with AI Integration the API keys are yours. And here is the part that usually raises an eyebrow: the booking product, the one that does the most, is the cheaper of the two. That is not a typo — it is already built and proven, and the work is configuring it with your services, your opening hours and your calendar, whereas AI Integration is built from scratch around your documentation, your channels and your systems, and no two are alike. What you pay for is the building, not the number of features. If you are unsure which one you need, the question is simple: are you losing unanswered enquiries, or uncaught bookings? And if it is bookings, do not pay for bespoke work: that one is already built.

Because it is not always the right call for you, and I would rather say so before charging you. If what you need is a three-page site you will barely touch, WordPress will do the job and someone will build it for less than I will: I am not going to pretend otherwise. What changes things is when the site has to do something besides look good — talk to your calendar, your management software or your WhatsApp, or take over something you do by hand today. On a template site that gets solved by adding third-party plugins, and every plugin is an update that can break something else, sometimes a yearly licence, and always someone to call who is not you. I write the code myself, so there are no twenty pieces from twenty different authors that have to get along. And I do the maintenance, which is the difference you actually notice in year two. If WordPress still turns out to be your best fit, I will tell you so in the diagnosis and I will not charge you for finding out.

Nothing renews on its own: for the services that include the Basic Plan for the first year (online shop, real estate and ERP/CRM) I tell you a month before it ends so you decide, and there is never a lock-in. From there it depends on what it is. What is yours stays yours: your website remains published and remains yours, with or without maintenance; what you lose is the safety net — monitoring, backups, updates, bug fixing and the monthly hour of changes — so if something breaks one day, you find out yourself and fixing it is quoted separately. What does need the fee to work, on the other hand, stops: Specific Automations, the Integration AI assistant and WhatsApp Appointments are switched off if you cancel the fee, with 15 days notice. It is not a punishment: that fee pays for watching that it keeps working and, for appointments, the cost of the AI model, which is included and I pay for it. That is why in those services the fee is mandatory while the service is running: mandatory does not mean lock-in, it means that if you cancel, the service stops working. And if you want to pick it up later, we look at the state it was left in and the catch-up is quoted separately.
