Frequently asked questions
What services does Wiser Zone Advice Co., Ltd. provide?
We provide bookkeeping, accounting system setup, audit support, accounting software training, company registration, tax advisory and tax planning, as well as advice on investment promotion from the Board of Investment (BOI) and the requirements that apply to foreign-owned businesses. Our office is in Samrong Nue, Mueang Samut Prakan.
How is the bookkeeping fee calculated?
The fee depends on the volume of documents each month, the number of transactions and how complex the business is, for example whether you carry stock and whether you are already registered for VAT. We assess this once we have seen the basic information, and we always quote a monthly fee before starting work.
We have just registered the company. When do we have to start keeping accounts?
You must keep accounts from the date the company is registered as a juristic person, and you must have a registered accountant in place. If this is left until the end of the accounting period, documents are usually missing and penalties follow. We recommend starting from the first month.
Do you work with companies that have foreign shareholders?
Yes. We advise on the requirements that apply to foreign-owned businesses, on matters relating to the Foreign Business License (FBL), and on keeping the accounts in line with the relevant conditions.
We want to move from our current accounting firm. Is that complicated?
It is not complicated. What you need to hand over is the most recent annual financial statements, the latest trial balance and the records your current firm holds. We check that the opening balances are complete before taking the work on, so that old problems are not quietly carried forward.
Not sure which service your business needs?
Tell us briefly what your business does and how the accounting is handled today, and we will tell you where to start and roughly what it costs. The first consultation is free.
