Technology built around real businesses.

Web · Product · Development · Automation · Artificial intelligence

+50 digital projects delivered by Digitup Studio. Without claiming specialisation where we don’t yet have public accountancy case studies.

An accountancy firm can have good software and still lose hours every day.

  • Emails everywhere

    Clients sending documents, questions, issues and requests to different people.

  • WhatsApp becomes another CRM

    Important conversations mixed among hundreds of messages.

  • Scattered documentation

    Emails, folders, Drive, server, ERP, WhatsApp and the client’s computer.

  • Repetitive work

    Requesting documents, chasing deadlines, copying information, drafting replies, classifying files.

  • Information stuck with people

    “Ask María — she knows where it is.”

  • Disconnected tools

    One app for accounting, another for payroll, another for documents, another for CRM — and lots of manual work between them.

We don’t want to replace all your software. We want everything to work better together.

We can integrate existing tools, build automation layers or develop custom systems for the processes that are truly specific to your accountancy firm.

01 / Digital presence

A website that isn’t just your business card

An accountancy firm constantly receives similar enquiries. The website can start working before your team replies.

  • “I want to become a sole trader.”
  • “I need to change tax advisor.”
  • “I’m hiring my first employee.”
  • “I want to create a company.”
  • “I’ve received a tax notice.”
  • “I need tax advice.”

  • Custom UX/UI
  • Technical SEO
  • Mobile first
  • Fast loading
  • Smart forms
  • Anti-spam protection

02 / Acquisition

The form can prepare the work before the first call

Instead of name, email and a generic message, we can build an intake that classifies the need.

What do you need?
  • Number of employees
  • Legal form
  • Approximate revenue
  • Current services
  • Software in use
  • Expected switch date
  • Type of activity
  • Expected partners
  • Desired legal form
  • Sole trader / limited company need
  • Sole trader or company
  • Taxes that concern you
  • Urgency (notice, filing, consultation)
  • Hires, terminations or contracts
  • Number of workers
  • Collective agreement / sector

03 / Visibility

Ready for how new clients search today

We build a solid technical foundation for traditional ranking and new discovery systems. We don’t promise to magically appear in ChatGPT: we build a technically correct, structured website that’s easy to interpret.

  • Technical SEO
  • Sitemap
  • Metadata
  • Structured Data
  • Canonical
  • Search Console
  • Core Web Vitals
  • Semantic architecture
  • IndexNow
  • llms.txt

But the website is only the entrance.

The biggest potential is behind it.

04 / Custom software

Your accountancy firm’s operating system

It doesn’t have to be another huge ERP. It can be a simple layer built exactly around how you operate.

If your clients already use WhatsApp, let’s make it part of the system

  • Check context and receive documents
  • Classify files and request documentation
  • Draft replies and send reminders
  • Route, assign an owner and human takeover

12 / Integrations

You don’t have to start from scratch

If you already use tools that work, we can integrate, sync, complement, migrate or build a new layer on top.

Digitup

  • Email
  • Microsoft 365
  • Google Workspace
  • ERP
  • Accounting
  • Employment software
  • CRM
  • Drive / OneDrive
  • Dropbox
  • Server
  • WhatsApp
  • Telegram
  • APIs

We don’t build something new when a better solution already exists.

If a standard tool perfectly solves a need, we can integrate it. We reserve custom development for specific processes, your own automations, team experience, tool integration and internal information.

13 / Process

Before we build, we need to understand how your accountancy firm works

  1. We sit down with your team

    We understand tools, processes and real problems.

  2. We observe day-to-day work

    Email, WhatsApp, documents, clients, tasks and software.

  3. We spot opportunities

    What consumes time, what repeats, what causes errors, what depends on one person.

  4. We design the solution

    Automation, integration, internal tool or platform.

  5. We build and evolve

    Design + development + AI. Then we add by impact.

Generic software vs adapted software

It doesn’t mean custom is always better. It means that when how you work is specific enough, it’s worth considering.

Standard software

  • The system defines the process
  • The team has to adapt
  • Many features
  • Limited integrations
  • Vendor roadmap

Digitup

  • Your process defines the system
  • We build what’s needed
  • We integrate existing tools
  • We can evolve it
  • AI adapted to your context

It doesn’t have to stop at the first version

We build in stages. Always prioritising what creates the most impact.

  • WhatsApp
  • AI Inbox
  • Documents
  • Portal
  • Automations
  • Copilot

We can keep owning the technical side

  • Infrastructure

    Hosting, APIs and services.

  • Monitoring

    Uptime and errors.

  • Security and backups

    Updates, reviews and backups when needed.

  • Integrations & AI

    Connections, prompts and continuous improvement.

Automation doesn’t mean losing control

  • Permissions

    Each user accesses the information they’re allowed to see.

  • Human review

    Critical workflows can require approval.

  • History

    Logging of relevant actions when needed.

  • Authorised sources

    AI can be limited to approved information.

Imagine that tomorrow…

  1. Carlos sends 8 invoices via WhatsApp

    The system identifies and organises them.

  2. An email arrives requesting an employee hire

    The client is identified and a request is created.

  3. AI detects pending documentation from 11 clients

    It sends the configured reminders.

  4. Laura opens ACME SL

    She has documents, messages, tasks and context in front of her. She doesn’t search for anything.

  5. A client asks on WhatsApp

    AI prepares the reply. Marta reviews it and hits send.

  6. Management checks what’s blocked

    The system answers.

None of these things is spectacular on its own. Together they can change an accountancy firm’s day to day.

You probably already have the software needed to do your work.

What you might be missing is a layer that connects everything.

You don’t need to arrive with a solution already figured out

Then we decide what makes sense: automate, integrate, improve or build.

  • Current software

    What you use and what works.

  • Incoming requests

    How they arrive and who receives them.

  • Communication

    Email, WhatsApp, phone.

  • Documentation

    Where it’s received and where it gets lost.

  • Work assignment

    How it’s distributed and what gets stuck.

  • Repeated tasks

    What a person shouldn’t be doing.

How many hours does your accountancy firm lose on things that could happen automatically?

We’re not here to sell you a CRM. We want to understand how you work and find where technology can genuinely save time.

Let’s talk

A process, a tool or an idea. That’s enough to start.

Or email us at hola@digitup.es

Your accountancy firm already has its own processes. Technology should adapt to them.
