View detailsWhy TRÍ TÍN quotes for each business
Two businesses of the same size can need very different levels of support. TRÍ TÍN quotes only after understanding the state of your books and your actual needs, so the fee reflects the real workload and responsibility — and stays the same as long as the scope of work does not change.
What we consider when quoting
- Your industry, field and specific business operations
- The volume and nature of transactions, invoices and documents
- The current state of your books: newly established, running smoothly, or in need of review or rework
- Your in-house accounting team and the level of support you need
- Advice needed beyond accounting and tax
- The scope of service you choose
