Day-to-Day Bookkeeping

So that the cooperation with our client would progress smoothly and without problems, we have compiled instructions on how the material necessary for day-to-day bookkeeping should be dealt with. If the company is obligated for declaration quarterly or once a year, same bookkeeping rules are applied.

For every transaction a company makes, there has to be a document for it. In bookkeeping, the document is used to confirm the transaction, and it must be provided by third party i.e. bank or a sales person. Transactional events that require documents are for example; sales, purchase and finance events. From these documents the bookkeeping material is constructed.

Most common documents that are required for bookkeeping:



Statement of accounts



Sales invoice, Cash flow report, Sales journal


Purchase invoices, purchase receipt


Rental agreement, Documents received from TAX administration, security certificate

Delivering the bookkeeping material:

  • Material should be delivered as soon as possible, after the end of each month, or by agreed timetable.
  • After the end of each month, there is a period of 1 month and 12 days to leave periodic tax returns notification and pay VAT.
  • Document requirements and markings:
  1. Documents must be related to business activities.
  2. Client is personally responsible for the correctness and justification of documents.
  3. If a purchase receipt provides no clear indication on the purpose of item or service, it is a good idea to add a written clarification to it.
  4. VAT must be clearly defined in purchase receipt, so that it can be deducted in taxation.
  5.  If a purchase receipt is not paid from company account or cash, we presume it is paid with entrepreneurs’ personal equity. If there are multiple entrepreneurs, you should clarify who has made the purchase.
