The issue isn&#039;t about avoiding bias, but about... <\/span><b>Explain the cause of the deviation.<\/b><span style=\"font-weight: 400;\"> and normalize the baseline.<\/span><\/li>\n<li><b> How is historical data processed?<\/b><b><br \/>\n<\/b><span style=\"font-weight: 400;\"> Retroactive adjustments should be avoided. The CFO should only map historical data at an aggregate level for comparison purposes, preventing confusion within the accounting system.<\/span><\/li>\n<li><b> Does the current ERP system need an upgrade?<\/b><b><br \/>\n<\/b><span style=\"font-weight: 400;\"> It&#039;s usually not necessary right away. The problem lies in the rules and input data. ERP upgrades should only be a step after the TT99 process has stabilized.<\/span><\/li>\n<li><b> What are the biggest risks of implementing Circular 99?<\/b><b><br \/>\n<\/b><span style=\"font-weight: 400;\"> It&#039;s not that it violates standards, but rather... <\/span><b>loss of operational control<\/b><span style=\"font-weight: 400;\"> This is due to expanded recognition rights but a lack of intermediate control layers.<\/span><\/li>\n<li><b> Is internal control more complicated?<\/b><b><br \/>\n<\/b><span style=\"font-weight: 400;\"> Conversely, if implemented correctly, Circular 99 provides more realistic control. The condition is that the CFO must redesign the approval and accountability flow.<\/span><\/li>\n<li><b> How long does it take to see the real benefits?<\/b><b><br \/>\n<\/b><span style=\"font-weight: 400;\"> Typically, after 2\u20133 reporting periods, when the data has stabilized and the management reports accurately reflect business operations.<\/span><\/li>\n<li><b> At what stage of life is Bizzi suitable?<\/b><b><br \/>\n<\/b><span style=\"font-weight: 400;\"> From the very beginning, Bizzi helped the CFO control the data and progress of Circular 99 implementation before everything became &quot;frozen&quot; in the ERP system.<\/span><\/li>\n<\/ol>\n<figure id=\"attachment_999980063\" aria-describedby=\"caption-attachment-999980063\" style=\"width: 667px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"wp-image-999980063 size-full\" src=\"https:\/\/bizzi.vn\/wp-content\/uploads\/2026\/02\/he-thong-tai-khoan-theo-thong-tu-99-2025-2.png\" alt=\"account system according to Circular 99-2025\" width=\"667\" height=\"724\" title=\"\" srcset=\"https:\/\/bizzi.vn\/wp-content\/uploads\/2026\/02\/he-thong-tai-khoan-theo-thong-tu-99-2025-2.png 667w, https:\/\/bizzi.vn\/wp-content\/uploads\/2026\/02\/he-thong-tai-khoan-theo-thong-tu-99-2025-2-276x300.png 276w, https:\/\/bizzi.vn\/wp-content\/uploads\/2026\/02\/he-thong-tai-khoan-theo-thong-tu-99-2025-2-11x12.png 11w\" sizes=\"(max-width: 667px) 100vw, 667px\" \/><figcaption id=\"caption-attachment-999980063\" class=\"wp-caption-text\">Payment voucher template according to Circular 99\/2025<\/figcaption><\/figure>\n<h2><span class=\"ez-toc-section\" id=\"Ket_luan\"><\/span><b>Conclude<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">From a CFO&#039;s perspective, the chart of accounts under Circular 99\/2025 should not be simply understood as a new list of accounts to replace the old one. Simply finding an Excel file of the chart of accounts under Circular 99 or downloading and directly importing it into the ERP system carries significant risks: the structure may be correct, but the underlying management principles are flawed.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Transitioning to a new accounting system requires CFOs to view issues at the data and control level. The key is not whether &quot;there are enough accounts according to Circular 99,&quot; but rather how those accounts are linked to costs, cash flow, KPIs, and approval flows in actual operations. Without redesigning accounting rules and recognition authority, the accounting system under Circular 99 will only increase accounting complexity without providing any management value.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A safe transition roadmap must ensure: input data is standardized before being entered into the ERP system, accounts are mapped according to business logic rather than just by name, and management reports remain comparable across transition periods. This is crucial for CFOs to correctly implement the accounting system according to Circular 99\/2025 while avoiding the risk of KPI discrepancies or prolonged closing times.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In practice, cost, invoice, and accounts receivable control platforms like Bizzi act as a pre-ERP control layer, helping to standardize data according to the chart of accounts structure as per Circular 99\/2025 right from the initial stages. As a result, CFOs can not only &quot;apply&quot; Circular 99, but also better control, make faster decisions, and maintain the stability of the company&#039;s financial system.<\/span><\/p>\n<p><em><strong>To experience the features of the solution and receive personalized advice for your business, register to schedule an appointment here: <a href=\"https:\/\/bizzi.vn\/dang-ky-dung-thu\/\">https:\/\/bizzi.vn\/dang-ky-dung-thu\/<\/a><\/strong><\/em><\/p>","protected":false},"excerpt":{"rendered":"<p>The accounting system under Circular 99\/2025 is becoming a major concern for many CFOs as the new accounting standards aim to\u2026<\/p>","protected":false},"author":56,"featured_media":999980065,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"content-type":"","inline_featured_image":false,"footnotes":""},"categories":[76,85],"tags":[],"class_list":["post-999980047","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-goc-nhin-cfo","category-kiem-soat"],"acf":[],"_links":{"self":[{"href":"https:\/\/bizzi.vn\/en\/wp-json\/wp\/v2\/posts\/999980047","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bizzi.vn\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/bizzi.vn\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/bizzi.vn\/en\/wp-json\/wp\/v2\/users\/56"}],"replies":[{"embeddable":true,"href":"https:\/\/bizzi.vn\/en\/wp-json\/wp\/v2\/comments?post=999980047"}],"version-history":[{"count":2,"href":"https:\/\/bizzi.vn\/en\/wp-json\/wp\/v2\/posts\/999980047\/revisions"}],"predecessor-version":[{"id":999980070,"href":"https:\/\/bizzi.vn\/en\/wp-json\/wp\/v2\/posts\/999980047\/revisions\/999980070"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bizzi.vn\/en\/wp-json\/wp\/v2\/media\/999980065"}],"wp:attachment":[{"href":"https:\/\/bizzi.vn\/en\/wp-json\/wp\/v2\/media?parent=999980047"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/bizzi.vn\/en\/wp-json\/wp\/v2\/categories?post=999980047"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/bizzi.vn\/en\/wp-json\/wp\/v2\/tags?post=999980047"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
