How accounting and advisory firms in Spain can win new clients
Specialisation, segmenting by size, the free review call and turning a conversation into a monthly fee. A method to stop depending on word of mouth.

Most Spanish gestorías and advisory firms grow by referral until they hit a ceiling. Word of mouth brings clients, but not the ones you choose. To grow with the clients you want, you need to go and find them. The same applies to international firms opening a Spanish practice.
1. Specialise
"Tax, accounting and payroll for SMEs" — every firm says it. "Advisory for dental clinics" or "for transport companies" — very few, and they charge more.
2. Choose the size
| Band | Need | Typical fee |
|---|---|---|
| Sole trader, no staff | Basic tax and accounts | Low |
| 1-9 employees | Tax, accounts and payroll | Medium |
| 10-49 employees | Everything plus consulting | High |
3. The review call
"We're doing free reviews for restaurants in the area: social security contributions, tax setup and deductible expenses that often slip through. Would you like us to look at it in half an hour?"
Specific, free and sector-related. The review is your shop window.
4. From review to monthly fee
Note two or three improvements and close with a clear proposal: what's included, monthly price and how switching works (you handle it all). The biggest barrier to changing firm is the hassle.
5. Consistency
Ten calls a week, every week, beats an intense one-month campaign. And always respect a no: it's a small market and reputation is everything.
Frequently asked questions

Those that fit your speciality. A client with 10 employees and payroll is usually more profitable than several sole traders, but also more demanding.
How do I compete with cheap online gestorías?+
With sector specialisation and personal service: knowing their sector and answering the phone.
