Is it worth automating your Holded? Ask yourself these 3 questions
For a freelancer or a small SME, the question is not whether the technology works, but whether the expense is justified. There is no universal answer, but there is an honest three-step calculation that tells you whether it makes sense in your specific case.
The short answer: yes, it can. Holded has a public API and an AI agent can connect to it today so your calls and WhatsApp conversations are handled and recorded without manual work. At Veltim we design and implement this integration: the first call is free and the quote is fixed. The rest of the article explains how.
Holded is the reference Spanish cloud ERP for small businesses and freelancers: invoicing, accounting, CRM and projects in an interface designed for those who don't want to wrestle with management software.
What Holded's API allows
Its documented public API covers contacts, invoicing, products and the CRM pipelines with API key authentication, enough for an external system to reliably create and query records.
That the API is public and documented matters more than it seems: it means the integration doesn't depend on hacks or opaque connectors, but on an official contract that the platform itself maintains. The full reference is in the Holded developer documentation.
What it automates (and therefore what it saves)
For Holded's typical customer profile — a small business without a dedicated salesperson — the AI agent acts as both a filter and a recorder: every relevant call or WhatsApp ends up as a contact with its note in the CRM, without relying on someone to write it down after hanging up. the client record and its invoicing history already live in the same place.
The principle is always the same: the AI agent handles the conversation and Holded finds out automatically. No writing on paper to transfer later, no leads lost between the phone and the CRM.
This integration performs best for Spanish SMEs and freelancers who invoice and manage clients from Holded.
What you should know beforehand
Holded's CRM is deliberately simple: for sales processes with many stages and large teams it falls short compared to a dedicated CRM, although for a small business that simplicity is precisely the advantage.
To be clear: none of these points prevents the integration. They are design decisions that we resolve before connecting anything, and that's why the quote we provide is fixed: the tool's limits are already accounted for. The rule is to design first and connect later: which records the agent creates, which it updates, and what always remains in the team's hands.
Frequently asked questions
We're two people, does this make sense?
It's the case where it makes the most sense: no one available for the phone and every missed call is a client. The agent answers, records in Holded and you review the list at the end of the day.
Does the integration touch invoicing?
Not by default: the agent works on contacts and CRM. The invoicing part remains as it is, although having the contact properly registered from day one makes invoicing later simpler.
Do I have to change tools to work with Veltim?
No. The integration is built on what you already use: the advantage of tools with a public API like Holded is precisely that they don't force any migration.
Who builds this integration and how much does it cost?
It is designed and implemented by Veltim, an AI automation agency from Madrid that works remotely across Spain. The price depends on your volume and what needs to be connected: in a free call we review your Holded account and give you a fixed quote with concrete timelines.
