CRM, inventory, order and stock management
East Asia Business System Development | Payment terms, batch traceability and multiple entities
Trade and wholesale centre on credit terms and batch traceability; retail chains centre on multi-store inventory and transfers; professional services centre on project hours and billing. We abstract what these three share before adding sector differences, so each client is not built from zero.
Scope of Business System Development
The activities below are the ones we own on this type of project, delivered in phases and confirmed item by item. Where third-party hardware or licences are involved, the procurement list, licensing requirements and responsibility split are set out at solution stage.
Approval workflows, contracts and financial reconciliation
Multi-store, multi-warehouse, multi-currency and multi-entity accounting
Integration with ERP, payment, logistics and tax systems
Reporting dashboards and operational analytics
Deliverables
Every item is archivable and transferable, so an internal team or a third party can maintain the system later.
- Current-state and target process maps
- Data model and permission matrix
- System source code, database scripts and migration plan
- API documentation and third-party integration records
- Training materials and acceptance report
Typical technology stack
Selected against the existing environment and the capabilities of your team, with maintainability and future extension in mind.
Implementation phases
Each phase produces a confirmable output and an acceptance record, so issues are resolved within the phase.
Phase 01
Process review
Map existing spreadsheets, legacy systems and manual steps; identify where duplicate entry and reconciliation cost the most
Phase 02
Scope and model
Confirm first-phase modules, role permissions and data migration boundary
Phase 03
Build and parallel run
Bring core modules live first, then validate data through a parallel run
Phase 04
Cutover and support
Retire the old system, archive data and provide a supervised stabilisation period
Compliance considerations in East Asia
For Business System Development, the requirements below directly affect data structures, page behaviour and deployment. We confirm each item during solution design; formal legal advice should be confirmed with a local adviser.
Act on the Protection of Personal Information (APPI) and statutory disclosure
APPI requires a defined purpose of use, restrictions on third-party provision, supervision of entrusted processors and handling of breach incidents. Consumer-facing e-commerce must disclose operator information, prices, payment methods, delivery times and return conditions under the Act on Specified Commercial Transactions; since October 2023, undisclosed paid promotions may constitute misleading representation.
Personal Information Protection Act (PIPA)
PIPA sets explicit requirements for obtaining consent, minimising collection, publishing the processing policy and supporting data subject rights (access, correction, deletion, suspension of processing); cross-border transfer requires separate notice and consent. Sites must provide a readable processing policy and consent records.
Personal Data (Privacy) Ordinance (PDPO)
The six data protection principles require lawful purpose, proportionate collection, consistent use, adequate security, openness of policy, and rights of access and correction. Direct marketing requires consent with an opt-out channel, and cross-border transfer requires attention to the actual protection available in the destination.
Law No. 8/2005 Personal Data Protection Act
Processing requires a legitimate basis, sensitive data is subject to stricter limits, and transfer abroad must meet statutory conditions. Sites need a collection statement stating purpose, recipients and retention period.
Personal Data Protection Act
Specific purpose, notification obligations, data subject rights and security maintenance measures are required. E-commerce and membership scenarios must notify the purpose, categories, period and recipients of collection, and provide channels for enquiry, correction and deletion.
Data transfer and local retention
Requirements differ across East Asia: Japan imposes notification and consent duties for provision to third countries, South Korea requires separate consent, and Hong Kong emphasises the actual level of protection. System design begins by mapping which data must stay local and which can be centralised.
East Asia cases involving this service
The following projects involve Business System Development. Each shows how the challenge was scoped and what was delivered.
Japan-China trading house order and credit management, Osaka
Client: Japan-China trading house in Osaka (food and household goods import and wholesale)
Challenge
Orders arrived by fax, email and telephone and were consolidated by clerks by hand. Payment terms varied by customer and credit limits were set from experience. Exchange-rate movement meant quotations were rebuilt from scratch, and month-end reconciliation and collection consumed substantial time.
What we delivered
- Single order intake: archived emails and faxes transcribed into structured records, with repeat orders duplicable
- Customer credit control linking limit, payment term and collection history, blocking excess shipments automatically
- Quotations generated against currency and exchange-rate snapshots, with version traceability
- Receivables management with ageing analysis, collection reminders and generated statements
Outcome
Order entry moved from manual transcription to structured capture with fewer errors. Excess shipments are blocked by the system, moving bad-debt risk forward, and reconciliation shifted from a month-end push to a weekly routine.
Multilingual ordering and reservations for a Chinese restaurant chain, Tokyo
Client: Chinese restaurant chain in Tokyo (five locations, including a tourist district branch)
Challenge
The tourist-district branch served many foreign guests with a Japanese-only menu and gesture-based ordering. Reservation calls could not be handled at peak. Each store ran a different POS, so head office had no consolidated data, and allergen information was incomplete.
What we delivered
- Multilingual menu (Japanese / English / Chinese / Korean) with QR ordering and allergen labelling
- Online reservations allocated by time slot and table type, with configurable overbooking rules
- Unified POS and head-office dashboard covering revenue, average spend, table turnover and dish ranking
- Membership and coupons usable across stores, with availability configurable per location
Outcome
Ordering friction at the tourist-district branch dropped noticeably. Reservations moved online, relieving front-desk pressure at peak, and head office can see dish mix and table turnover by store for the first time.
Beauty retail stores and membership system, Seoul
Client: Chinese-owned beauty retail brand in Seoul (eight stores plus online shop)
Challenge
Online and in-store membership were separate, so points could not accumulate. Promotions conflicted between channels, stock sat in individual stores while the online shop sold out, and local Korean payment methods were only partially supported.
What we delivered
- Unified membership and points: one account across channels, with shared points and tiers
- Omnichannel inventory allowing store stock to fulfil online orders, with automatic store routing on shortage
- Promotion engine with rules by channel, member tier and product to prevent price conflicts
- Local payments and identity verification integrated with commonly used Korean methods and real-name requirements
Outcome
Once points were unified, repeat purchases across channels entered one data set. Promotion rules became consistent and price conflicts disappeared, while store stock can serve online orders, reducing simultaneous stockouts and overstock.
Cross-border supplement store with subscription, Hong Kong, China
Client: Cross-border supplement brand in Hong Kong, China (serving Chinese customers in Southeast Asia and North America)
Challenge
Marketplace commissions consumed margin, and an independent store needed cross-border payment and logistics. Subscription repeat purchase had no system support and was tracked in manual spreadsheets. Health claim restrictions differ by market, leaving copy exposed to compliance risk.
What we delivered
- Independent store in Traditional Chinese and English, with categories organised by benefit and audience
- Subscription management with self-service cycle, discount, pause and skip
- Cross-border payments and logistics: multi-currency collection, international shipping and duty notices
- Content compliance: claim wording reviewed against each target market before publication
Outcome
The store captured repeat customers outside the marketplace, and subscription revenue became more predictable. Front-loading claim review reduced rejections by platforms and advertising channels.
Japan-bound travel platform with itineraries and ticketing, Taipei, China
Client: Travel platform in Taipei, China (independent and group travel to Japan)
Challenge
Product combinations were complex and quotations calculated by hand. Tickets and local experience suppliers were confirmed by email, and overbooking occurred in peak season. Customer service handled itineraries, payments and rescheduling together, slowing response.
What we delivered
- Product and inventory management by date, party size and room type, with automatic overbooking blocks
- Package quotation separating cost and sale price for flights, hotels and local experiences
- Supplier integration automating confirmations, vouchers and settlement statements
- Traveller pages with itinerary handbook, e-vouchers and rescheduling requests
Outcome
Peak-season overbooking effectively disappeared. Quotations are generated by the system rather than calculated manually, freeing customer service from status enquiries to handle genuine exceptions.
Property agency listing and CRM system, Macao, China
Client: Property agency in Macao, China (residential and commercial leasing and sales)
Challenge
Listings were scattered across agents’ phones and printed flyers. Viewing records were inconsistent and follow-up relied on memory. Website listings lagged, so clients arrived to find a property already sold. Commission allocation rules were complex and settlements were frequently disputed.
What we delivered
- Listing database with unified fields, images and status, searchable by district and type
- CRM covering lead source, viewing records, follow-up reminders and intent grading
- Website listing synchronisation reflecting status changes immediately and hiding withdrawn units
- Commission rules configured by role and transaction condition, with generated settlement statements
Outcome
Listing status matches the public website, removing the awkwardness of a sold unit still advertised. Client records returned from individuals to the company, and commission settlement now follows stated rules, reducing disputes.
Precision parts production and quality traceability, Yokohama
Client: Precision parts manufacturer in Yokohama (Chinese-owned, serving Japanese OEMs)
Challenge
Customers require inspection certificates by batch, but data lived in paper records and spreadsheets. Equipment utilisation was unclear, so delivery commitments were conservative. When defects occurred, traceability meant searching several record books.
What we delivered
- Work order and routing management capturing progress, good quantity and defect registration in real time
- Batch traceability binding raw material to finished goods, with generated inspection certificates
- Equipment data acquisition analysing utilisation and downtime causes on key machines
- Delivery date prediction based on capacity and work in progress
Outcome
Inspection certificates moved from two or three days of manual consolidation to direct system output. Utilisation data gives delivery commitments a factual basis, and defect traceability is a batch query rather than a records search.
IT service desk ticketing and knowledge base, Tokyo
Client: Chinese-owned IT service provider in Tokyo (managed services for companies in Japan)
Challenge
Support requests arrived by phone and email, engineers recorded them individually, and response time could not be measured. Recurring issues were re-investigated each time because knowledge stayed with individuals. Monthly client reports were assembled by hand.
What we delivered
- Ticketing across multiple channels with priority, SLA timers and escalation rules
- Knowledge base structuring symptoms, causes and resolution steps with full-text search
- AI assistance recommending similar tickets and drafting first responses for engineer approval
- Automated monthly service reports per client, including SLA attainment
Outcome
Response times became measurable and SLA performance evidenced. Recurring faults can cite prior resolutions directly, and monthly reports are generated rather than formatted by hand.
Case note: client names are anonymised under confidentiality agreements; cases are presented to explain implementation approach and delivery boundaries, and specific figures are subject to project acceptance records.
Business System Development FAQ
The first three answers are general; the last two address conditions specific to East Asia.
Can you extend an existing ERP?
Often, yes, but it is worth assessing first. Where the ERP exposes standard APIs we build peripheral systems and integrate; where only source modification is possible, we assess upgrade risk before committing.
Will data migration lose records?
We take a full backup and build a field mapping table, then run a trial migration and reconcile totals and sampled records. The legacy database stays read-only on cutover day until sign-off.
Will it cope with concurrent users?
Sizing follows expected concurrency. With sound indexing and caching, typical SME systems handle tens to hundreds of concurrent users; peak or bulk-entry scenarios are load tested as part of the plan.
How are timelines and meeting times arranged for Business System Development in East Asia?
Meetings and confirmation points follow the working hours common in East Asia (UTC+8 / UTC+9, 1–2 hours ahead of Chengdu). Requirements and solution design include a written progress update every week; development delivers a runnable build every two weeks. For cross-timezone work, key confirmations are placed inside the overlap of both working days, so progress never stalls waiting on a reply.
Which local compliance requirements should be confirmed in advance for Business System Development in East Asia?
Projects in East Asia typically involve Act on the Protection of Personal Information (APPI) and statutory disclosure, Personal Information Protection Act (PIPA), Personal Data (Privacy) Ordinance (PDPO). These requirements directly shape data structures, page behaviour, hosting location and data retention, so each is confirmed at solution stage and recorded in the delivery documentation. Formal legal advice should be confirmed with a local adviser.
