Custom software & AI for accountancy firms

Digitup Studio projects start at €1,000 and are delivered from 2 weeks. Above that minimum, the price depends on what the system has to do, which channels work comes in through (web, email, WhatsApp), which tools it connects to (email, shared folders, accounting software, CRM) and how much documentation it handles. A website assistant with your firm’s information sits closer to the minimum; integrations or a bespoke internal system raise the price. Depending on the project, payment can be by milestones, spread over 6 or 12 months, or a monthly fee, as we explain on our ways of working page.

The minimum delivery time is 2 weeks, for small, well-defined scopes. A first working version can usually be validated within weeks if the scope is clear; if several tools must be connected or a client portal built, the work is organised in more phases. We don’t work to a standard number of weeks: we set the schedule once we understand how your firm operates and, as with any custom software, we build in stages, starting with whatever has the most impact, such as document intake or email sorting. If you need something ready in under 2 weeks, we’re not the right option.

Usually yes: the idea is to work with what you already use, not start from scratch. We can connect Microsoft 365, Outlook, Gmail, Google Workspace, Drive, OneDrive, Dropbox, your own server, ERP, CRM, WhatsApp and Telegram. With accounting or payroll software, the integration depends on it offering an API or a reliable data export, and that is the first thing we check, before committing to anything. If a tool works, it stays: we build a layer on top, sync data or migrate in parts. The usual approach is to join up what you already have with automations that stop people copying information by hand from one program to another.

An accountancy firm handles tax, payroll and banking data of its clients and their employees, so each workflow is designed around how sensitive the information is: per-user permissions, data separation, action logs, protected credentials, backups and human review at critical steps. The AI provider and model are chosen together with you based on privacy, cost and type of task, and an internal copilot can be limited to authorised sources through RAG. As data controller, the firm decides how to meet GDPR and its duty of confidentiality: we don’t give legal advice, and we build to the requirements you set.

Repetitive work around documents and messages automates well: identifying the client writing by email or WhatsApp, sorting and renaming invoices, payslips and tax forms, extracting tax IDs, dates, amounts and periods, chasing missing documents with reminders, creating requests and tasks, flagging deadlines and preparing drafts from your templates. On WhatsApp, an AI assistant can handle the simple things and pass the conversation to a person. What we don’t automate is professional judgement: how a transaction is taxed, reviewing and filing a return, replying to a tax authority request or signing. AI organises and prepares; the advisor reviews and decides.

Digitup Studio is a technical studio in Madrid, founded in 2019 and led directly by its two partners. Stas Nikitin, CEO, handles product, business definition and project management; Anton Zverev, CTO, leads architecture and development, with more than 10 years building digital products. They are your contacts from start to finish, and the project doesn’t pass to a junior team after the first meeting. Depending on what is needed, specialists from our network in UX/UI, frontend, backend, data or AI join in, but the people responsible don’t change. You speak with the people who make the decisions.

Not yet: our website doesn’t publish any case study of an accountancy or tax advisory firm, and we would rather say so than pretend a specialisation we can’t yet show. We have built more than 50 projects since the start, and our case studies include systems with similar logic: the back office with job assignment and statuses we built from scratch for Tasaciones.com, the internal order system with notifications for Deliciosos Ramos, or the RAG over the cruise catalogue for Mundomar Cruceros. On the first call we show you the projects closest to your case.

With a 30-minute, no-obligation call with Anton Zverev, the CTO. You don’t need to arrive with a solution in mind: it’s enough to tell us which software you use, how requests arrive, where documentation is received and which tasks repeat every day. We review the case, propose a technical approach and phases, and also tell you if we think it isn’t worth building. If it fits, we start with a first, tightly scoped version. If you’d rather have a full analysis before deciding, with a process map and prioritised opportunities, we can begin with an AI audit.
