Five industries. Five tailor-made builds

Every project starts from the client's sharpest pain point and ends in a system that runs, gets used, and shows results. Two new SME custom ERP cases in 2026: metal machining and food processing.

Accounting firm / professional services

Great River CPA
AI intake automation

Great River CPA · grcpa.tw

Built for Great River CPA in Beitun, Taichung, led by CPA Hung Hsiang-wen: online company registration, AI industry profit-standard recommendations, 1,211 Ministry of Finance tax-rate records, 6-category multi-file upload and a LINE Bot service desk.

  • Native PHP 8.3 MVC + Hostinger deployment
  • AI recommendations + industry profit standards
  • LINE Bot support + PaymentFlex quoting
  • Site-wide SEO + AISEO rollout
Challenge

Challenge

A traditional firm handles each registration with repeated manual rounds: the client fills a form, the firm checks it, documents are amended, industry tax rates are compared, a quote is issued, payment is chased, and intake is tracked. The whole flow averaged 14 days, with hundreds of cases a week, and the CPAs' time went to intake busywork.

Solution

OTSM's solution

An 11-stage workflow, from the v2 application form and AI industry analysis to the v2 document manager, industry tax-rate lookup, extra-item pricing, admin selection of the lead candidate, and automatic PaymentFlex on quote_sent, all online. It integrates the g0v company data mirror, the Ministry of Finance FY114 industry profit-standard database, and automated SEO rollout.

We used to chase each case for missing documents three times. Now the system sends reminders automatically and the AI suggests the tax rate, so our accountants can focus on advising instead of playing customer service.

Resort manor / hotel and dining

Shire International · Warm Valley Manor
Instant quoting system

Shire Int'l · Warm Valley Estate

Built for Warm Valley Manor, a long-weekend and group-booking favorite: wedding, staff-trip and private-hire quotes that once took 1–2 days now reach the client within 30 seconds of the form being submitted.

  • Online dynamic quote engine
  • Live pricing by headcount / menu tier / add-ons
  • Formal PDF quotes sent automatically
  • One-click close-rate tracking in the sales admin
Challenge

Challenge

Inquiries for manor weddings, staff trips and birthday hires surged, and each quote depends on headcount, menu tier, lodging and add-ons. Sales had to price it by hand in Excel, export a PDF, then send it by LINE or email — an average of 1–2 days. Clients compare vendors fast, and often booked elsewhere before the quote arrived.

Solution

OTSM's solution

We built an instant quoting engine: every package, add-on, holiday surcharge and group discount rule was parameterized. On the front end the client picks headcount / date / package with sliders, the system prices it live and generates a standard PDF quote, then emails it to the client and the sales admin. A LINE push goes out alongside it, so the client has a quote in 30 seconds and sales follows up within 24 hours.

Weekends used to be our sales team's biggest headache. Now a customer asking online at midnight gets a quote in seconds, our reps only follow up on the tricky cases, and our close rate has doubled.

Group marketing / data analytics

Yuanmeng Group
Automated multi-platform traffic reporting

YuanMeng Group · Multi-Channel Analytics

Built for Yuanmeng Group, whose units span real estate, education, dining and event planning: it consolidates traffic from FB, IG, the website, YouTube and LINE OA, and produces an executive dashboard and a LINE report every day.

  • FB / IG / GA4 / YouTube API integration
  • LINE report pushed daily on schedule
  • Keyword monitoring + traffic anomaly alerts
  • Per-unit performance heat-map comparison
Challenge

Challenge

The group runs 5 business units, more than 20 social accounts and a website. The marketing lead had to screenshot each back office by hand, assemble Excel sheets and build a monthly report. Collecting the data alone ate a week of the team's time every month, and the boss could only see "yesterday's ad results" at the following Wednesday meeting.

Solution

OTSM's solution

We built an automated multi-platform API service: through Meta Graph, Google Analytics 4 and the YouTube Data API, LINE Notify and our own site tracking, each unit's core KPIs (views, engagement, conversion, cost) are pulled in automatically overnight. Executives get the LINE report at 8:00 in the morning, the dashboard finishes its full heat map by 11:00 and traffic anomalies alert the marketing owner immediately.

Precision metal machining / manufacturing

Juchuan Metal
Order-to-reconciliation custom ERP

OEM / ODM machining plant · Changhua · 25 machines

A custom SME ERP for a precision metal machining plant in Changhua: LINE inquiry parsing, paper OCR intake, quote comparison, outsourced purchasing, goods inspection, auto scheduling, and tooling costs charged through to finance — 11 stations on one line.

  • Laravel + MySQL · one-click release on Hostinger LiteSpeed
  • LINE / Email / paper — three intakes auto-converted
  • Auto scheduling by client tier, margin and due date
  • 155 accounts · 10 financial reports · seven-role access
2026 · Core modules done, samples in field test before go-live
Challenge

Challenge

Inquiries arrived through three entry points — LINE, email and paper — then were copied by hand into quotes and work orders. Outsourced purchasing and goods inspection were tracked on paper. Scheduling relied on senior operators' judgment, so margin and due dates could not both be met, and month-end reconciliation meant flipping through several ledgers.

Solution

OTSM's solution

We split "inquiry → quote → order → outsourced purchasing → IQC / FQC → production scheduling → scan-based operations → shipping → financial reconciliation" into 11 workflow stations. The LINE official account parses inquiries automatically, paper is OCR'd into orders, and email inquiries are parsed by AI. Scheduling computes a priority score from client tier, margin and due date. Tooling costs are charged to the work order, and BOM inventory plus finance documents were built alongside. Assembled from OTSM ERP Core standard modules, customizing only what machining truly does differently.

Food processing / poultry cutting

Jiyougu
Visual ordering × processing ERP

Client PWA · internal admin · driver delivery app

Restaurant clients pick cuts and specs from photos and order themselves; each order splits automatically into a floor work order and an accounting sales order. Variable processing pricing, client tiers, BOM stocktaking, auto restocking, the finance module and a driver delivery app all shipped together.

  • Laravel 13 + PHP 8.4 + MySQL · PWA
  • One order splits into work order + sales order
  • LINE inbox · Android driver app
  • Auto restock from supplier sheets · five-role access
2026 · In development, iterating
Challenge

Challenge

Restaurant clients ordered by LINE or phone, describing items out loud. Each order had to produce both a floor work order and an accounting sales order. Processing fees floated with specs, and long-standing clients had tier pricing. SKUs exploded from a dozen or so to several hundred as cutting combinations and packaging specs multiplied, and month-end reconciliation was manual.

Solution

OTSM's solution

The client side became a photo-based self-service ordering PWA; once an order lands, it splits automatically into a work order (floor) and a sales order (accounting). Variable processing pricing, client tiers, flow-based inventory with BOM stocktaking, auto restocking from supplier sheets, quote management and a finance module with 155 built-in accounts were all built together. A LINE inbox centralizes client messages, and the driver delivery app confirms drop-offs.

Custom project process

From first consult to live operations, OTSM guides your digital transformation in 4 steps.

  1. STEP 1
    Free requirements consult

    A 30-minute online or on-site session where an engineer hears your pain points and gives a feasibility and budget read on the spot.

  2. STEP 2
    Proposal × quote

    Within 3–5 working days you get a full proposal, flow charts, module plan and three-stage payment terms — compare with no pressure.

  3. STEP 3
    Build × test

    Agile development with a weekly demo of progress. A test environment lets you try it yourself and request changes, so what we deliver is ready to use.

  4. STEP 4
    Launch × operations

    Staff training, operating manuals and 24h LINE support. Later iterations and cloud hosting stay supported without a break.
