discount percentages to avoid discrepancies between quotations, purchase orders, and invoices.<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Discrepancies in reconciliation often arise from rounding: rounding % before or after pricing, rounding on individual lines or the total invoice.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To avoid discrepancies between quotations, purchase orders, and invoices, businesses need to standardize rounding when calculating discount percentages according to the following principles:<\/span><\/p>\n<ul>\n<li><span style=\"font-weight: 400;\">Do not round % before calculating the price: <\/span>Always use the % method to calculate the discounted price, only rounding at the final step.<\/li>\n<li><span style=\"font-weight: 400;\">Rounding is based on unit price, not on %: <\/span>Round the net price after the discount according to accounting regulations (VND \/ 2 decimal places), and use that price throughout the quotation \u2013 purchase order \u2013 invoice.<\/li>\n<li><span style=\"font-weight: 400;\">Standardized rounding of grades: <\/span>The regulations clearly state whether rounding should be done line-by-line or on the total invoice; mixing the two methods is strictly prohibited.<\/li>\n<li><span style=\"font-weight: 400;\">Issue an internal rounding policy: <\/span>Clearly state the number of decimal places, the rounding rule (round half up), and the system used as the standard. With a consistent rounding policy, the three-way reconciliation (PO\u2013GR\u2013Invoice) will match immediately, reducing rework and price disputes.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\"

However, with large datasets, numerous conditions, or real-time requirements, audits, and ERP integration, Excel is prone to exceptions, discrepancies, and hidden costs. Therefore, it&#039;s advisable to standardize formulas, apply rules, rounding policies, discount caps, and combine automation\/ERP if the volume and risk are high.<\/span><\/p>\n<p><em><span style=\"font-weight: 400;\">To receive consultation and experience our corporate financial management solutions, register here: <a href=\"https:\/\/bizzi.vn\/dang-ky-dung-thu\/\">https:\/\/bizzi.vn\/dang-ky-dung-thu\/<\/a><\/span><\/em><\/p>","protected":false},"excerpt":{"rendered":"<p>Trong doanh nghi\u1ec7p, c\u00e1ch t\u00ednh ph\u1ea7n tr\u0103m gi\u1ea3m gi\u00e1 kh\u00f4ng ch\u1ec9 l\u00e0 b\u00e0i to\u00e1n s\u1ed1 h\u1ecdc.
