Frequently asked questions

About our services.

Can I hire a single service or does it have to be a package?+

Each service can be hired independently. The norm, however, is that real-world operations activate two or three services simultaneously. For example: a Spanish company opening a subsidiary in Mexico typically needs corporate setup, international tax and monthly accounting bookkeeping.

In the first diagnostic meeting we identify exactly which services the operation requires and propose fees broken down by area.

Do you work with companies that already have an advisor in Spain?+

Yes. Many clients turn to Avenor for specific international matters while keeping their usual local advisory. In those cases we coordinate with their accountant or firm to avoid duplications. The condition is that the coordination is clearly defined from the start, in writing.

Do you have experience with complex structures?+

Yes. The international taxation, transfer pricing and crypto assets areas inherently require handling of high technical complexity. For operations that require larger teams, we complement with selected correspondents while keeping coordination at Avenor.

How are fees calculated?+

Three models depending on the service:

  • Fixed project fees: for one-off operations with defined scope (subsidiary opening, transfer pricing study, crypto filing, etc.).
  • Monthly retainer: for recurring bookkeeping and ongoing advisory.
  • Hourly fees: only for one-off technical consultations that do not fit the above.

Always agreed before starting, in writing.

Do you handle urgent matters?+

For active clients, the usual response time is 24 business hours. For tax emergencies with statutory deadlines (notices from the Spanish Tax Agency, requirements from the Mexican SAT, Form 720/721 deadlines) we prioritise same-day response. For new clients with urgency, we try to schedule a consultation the same day whenever the calendar allows.
