"I have the pleasure of knowing Silvana as an excellent professional — with incredible skill and outstanding efficiency. When my company needed to dispute an IRD penalty related to GST, Silvana stepped in and the amount went from a significant figure down to zero. In just one hour she resolved everything. She offers excellent services, with fair prices and remarkable professionalism. I recommend her 100%. She also speaks Spanish, which gave us extra confidence — you can ask anything and she explains everything clearly, without missing a single detail."

"Working with Silvana Castagnoli and ASU Accounting & Financial Services has been very valuable for the development of our company, AC2 Interiors. Her support in accounting and financial matters has played an important role in helping us structure and grow our business in a more organised and professional way. Silvana is always approachable, proactive, and very responsive when changes or new situations arise. We particularly value her positive attitude, clear communication, and willingness to adapt to the needs of a growing business. We highly recommend Silvana and ASU to any company looking for reliable and professional accounting support."

"We had the opportunity to use ASU's accounting services a few years ago, and their work truly stands out for its professionalism and reliability. Their support adds real value, not only through their strong accounting knowledge but also through their commitment to delivering excellent service. Silvana's personal approach makes a real difference — she genuinely cares about providing the best for her clients. JV Construction & Interior highly recommends their services."
