A5 Closer is an AI sales assistant built for LINE commerce. Combining Gemini Vision product recognition, 3 AI personalities and AMEGO e-invoicing, it catches every enquiry that arrives at midnight and turns every "too expensive" into an order.

Pain points · What happens every day

If any of these situations has you stuck, A5 Closer was built for it.

No reply at midnight, orders walk away

Customers message after work, but your staff has gone home. By morning they have already bought elsewhere.

New hires cannot memorize every script

300 products × 50 FAQs × 20 discount plans — a new agent needs 2 months to ramp up.

One "too expensive" and the sale is dropped

Agents fear pushing too hard and cannot handle objections, so close rates stay stuck.

A wrong answer on a sensitive issue blows up

Emotional replies cause bad reviews, returns and complaints the owner cleans up every week.

Features · Six core capabilities

Every feature was shaped by a real user pain point.

Gemini Vision product recognition

A customer sends a product photo and the AI identifies it within 3 seconds and returns a buy link. Blurry shots, rival products and magazine clippings all match.

Knowledge base: train it, ship it

Upload product manuals, FAQs, sales scripts and brand tone; the AI absorbs them and starts work at once, with no engineer tuning prompts.

Objection signals handled automatically

When a customer says "too expensive", "let me think about it" or "it is cheaper elsewhere", the system triggers the matching rebuttal and keeps the deal alive.

3 AI personalities to choose from

Sunny and warm, calm and professional, or friendly local — customers pick the style they like, and retention rises clearly.

Sensitive cases routed to a human

High-risk signals such as emotion, returns or complaints are routed to an agent, with an AI summary and a sentiment read attached.

AMEGO e-invoices issued automatically

Close a deal and the e-invoice is issued and sent to the carrier — payments, invoicing and CRM in one integration, with no accounting work at all.

How it works · The process

Four steps from start to running.

  1. STEP 1
    Connect your LINE Official Account

    Set the webhook in 5 minutes to link your LINE OA to A5 Closer. Existing staff messages and bot menus are all kept.

  2. STEP 2
    Upload knowledge + set the personality

    Upload product CSVs, FAQs and sales scripts in one click. Offer 3 AI personalities for customers to choose.

  3. STEP 3
    AI takes the lead + human relay

    The AI catches midnight messages instantly; on a sensitive keyword or a customer request, it hands over to a human with a sentiment summary.

  4. STEP 4
    Read the data + keep tuning

    The dashboard shows conversion by AI personality, which rebuttals fired and where customers stall, so you tune week by week.

Use cases · Who it fits

Not sure it fits you? Start with these scenarios.

E-commerce brand owners

Shopify, SHOPLINE and self-hosted store owners: turn LINE from a support desk into an automatic sales channel.

Sporting goods / equipment stores

The same solution Heat Sports uses. A customer sends a glove photo; the AI pulls the model, checks stock and quotes a bundle price.

Online courses / coaching

Course enquiry → AI recommends the right plan → straight to the sign-up link and payment, with zero human involvement.

High-ticket membership services

Venue buyouts, gym memberships, meal-box subscriptions — no midnight enquiry is missed, and proposals go out 24 hours ahead of rivals.

FAQ · Common questions

The questions we hear most about A5 Closer.

Another question? Leave a message at the foot of the page; we reply within one business day.

Will the AI answer at random or give wrong information?

For questions outside the knowledge base, the AI says "I do not know, let me transfer you to a specialist" instead of guessing. Every conversation can be reviewed, corrected and fed back into training.

Our support process is very complex — can the AI really learn it?

Yes. The system supports multi-turn scripts, conditional branches and variable insertion. Onboarding consultants also help you break the process down and go live.

Is the conversation data with customers secure?

HTTPS end to end, servers in Taiwan, customer data used only for conversations. A dedicated database and full data destruction can be requested.

Can it integrate with my existing ERP / CRM?

Pro and above open up webhooks and APIs. Enterprise adds custom integration (Shopify, Crescendo Lab, SHOPLINE and others have ready-made connectors).
