Articles on import and sales operations and on adopting an ERP, grouped by reader.
ERP is a system that records all buying, selling, stock and money in one place. Using a small shop as the example, this article explains what ERP does, when it is worth the effort, and when it is not yet.
M&C ERP is built on ERPNext, an open-source ERP that runs on the Frappe framework. This article explains the two names, their licences, and what the GPL means for a company that only uses the software and does not resell it.
ERPNext can do a lot, but not every shop needs it right away. This article lists the signs that a till and a spreadsheet are still enough, what to have in place before switching, and how to prepare so a later switch is easier.
In M&C ERP the display language is set per account: Japanese, Vietnamese or English, while documents and figures stay one set. What changes with the language, what does not, and what to check in the demo.
A stock spreadsheet usually has columns for the item name, the quantity and a few notes. ERPNext splits the same information into items, warehouses and the documents that change stock. This article compares the two, explains how to bring in opening stock, and what you gain after switching.
freee会計 and 弥生会計 are two accounting packages in Japan. ERPNext is an ERP that records buying, selling, stock and accounting. This article compares scope, cost and how each vendor describes Japan's invoice system, from their official pages (viewed 2026-11-12), to show which jobs belong to accounting software and which to an ERP.
Airレジ and スマレジ are POS register apps that run on an iPad. ERPNext is an ERP that records purchasing, stock and accounting too. This article compares scope, cost and devices from the official pages of Airレジ and スマレジ (viewed 2026-11-12), so a shop can see which kind it needs.
ERPNext is an open-source ERP; Odoo has an open-source Community edition and an Enterprise edition under its own licence, so the two split free and paid parts very differently. This article compares licences, how each charges, Japanese language and Vietnamese localisation, based on each vendor's official pages (viewed 2026-11-12), and lists questions to ask before choosing.
Each machine imported from Japan has its own serial number. M&C ERP records the serial number at warehouse receipt, ties it to the customer's delivery note, and uses it to tell at once whether a warranty claim is in or out of warranty. Partial deliveries and returns of faulty goods are covered too.
The purchase price from a Japanese supplier is not yet the cost of goods. M&C ERP calculates import duty and import VAT from the customs declaration, gathers landed costs such as duty, freight, inspection and storage fees in one document, and allocates them to the cost of each item, so gross profit reflects what the goods really cost.
Japanese companies with a base in Vietnam often have to send Japanese-style quotations, delivery notes and invoices to Japanese customers. M&C ERP has A4, Japanese-language print formats for 見積書, 納品書 and 適格請求書, printed straight from the documents in the system. What each format contains and what to check before using them for real.
The HS code is the basis for the import duty of each item. M&C ERP stores the HS code on the item together with the classification basis, the approver and the approval time, and does not let a customs declaration be submitted while an item's HS code is unapproved. How it works and why.
In M&C ERP each import shipment is its own document linked to a purchase order, with an estimated arrival (ETA), an actual arrival (ATA) and a status that runs from booking to warehouse receipt. How to track it, how to find late shipments, and the air freight and partial delivery cases.
ERPNext charges no licence fee per user, but using it still costs something. This article lists the costs of an open-source ERP in three stages (getting started, every month, over time) so a shop can estimate them before deciding.
An M&C ERP demo account lasts 30 days. How to get the account, a few things to know about the demo, and a week-by-week checklist so those 30 days answer the question "does this system fit our company?".
ERPNext is open source, so anyone can download and install it. But "installed" is not the same as "usable every day". This article lists what you take on when you install it yourself, what is worth handing to an implementer, and the questions to ask before choosing.
