I would recommend Liaison, particularly for VAT re-reviews. The whole process for the VAT reviews is simple and Andy, the VAT manager who completes our reviews, is really thorough and knowledgeable. VAT savings over the past 2 years total £497,000. Process wise, once the data is sent over to Liaison, they go and complete the review, sending their findings once fully completed. There may be some queries arising from their findings, but Andy always responds in a timely manner and provides a full response to quickly resolve.
