Who it's for

  • E-commerce brands drowning in "where is my order" and returns questions
  • Shopify and WooCommerce stores without a 24/7 support team
  • DTC brands that lose sales when pre-purchase questions go unanswered
  • Lean teams that want AI to handle tier-1 so humans handle the hard cases
  • Stores whose support is email-only and too slow to convert shoppers
  • Anyone paying for a helpdesk that still leaves customers waiting hours
  • Teams that added a chat bot and found the phone queue completely unchanged

How it works

  1. 1

    Shopper reaches out on any channel

    A customer calls, texts, or emails with a question: order status, a return, sizing, availability. Callsy picks up instantly, 24/7, in your brand voice, no ticket form and no queue.

  2. 2

    Ava answers and resolves

    It pulls order and product context, answers WISMO, returns, and pre-purchase questions, and takes the next action: sends tracking, starts a return, recommends a product. It resolves the request, not just logs it.

  3. 3

    Escalates the rest with full context

    Anything it shouldn't handle is warm-transferred or handed to your team with a full transcript and summary, so a human skips the back-and-forth and picks up where Ava left off.

Why it works

  • Most support volume is repetitive tier-1: order status, returns, sizing. Resolving it instantly frees your team and delights shoppers.
  • Speed converts. A pre-purchase question answered in seconds saves a sale that an email-in-four-hours loses.
  • Voice, SMS, email, and WhatsApp in one agent means customers reach you the way they prefer, not only through a ticket form.
  • It's an AI agent, not a chat widget. It takes actions (tracking, returns, recommendations) instead of posting canned replies.
  • Every conversation is logged with a transcript, so your team gets context and your customer data stays clean.
  • EU-native and GDPR-first, with AI disclosure built in, so it's compliant out of the box.
  • Phone is the channel that actually costs you. An agent can hold several chats at once but only one call, so voice capacity scales almost directly with headcount. That's why automating a smaller share of calls often saves more than automating a larger share of chats, and why most support AI, which is chat-only, never touches the expensive queue.
  • Escalating well beats deflecting hard. Handing a human a call that's already identified and triaged cuts handle time on the calls AI can't resolve, which is where a containment-obsessed setup leaves value behind.

Why the phone line is the one worth automating

Relative cost to serve one contact, indexed to phone at 100. An agent can hold several chats at once but only one call, so voice capacity scales almost directly with headcount.

This is why deflecting a smaller share of calls often beats deflecting a larger share of chats.

Customer
Hi, I ordered a jacket last week and I still haven't got any shipping update.
Ava
Happy to check that for you. Can I take your order number, or the email you used to order?
Customer
It's the gmail one, order 48213.
Ava
Got it. Your order shipped yesterday and it's out for delivery today. I'll text you the tracking link now. Anything else while I have you?
Customer
Actually, can I change the size to a medium?
Ava
It's already on its way, so I can set up a free exchange for a medium the moment it arrives. Want me to start that?

Frequently asked

Is Callsy an AI customer service agent or a chatbot?

It's an AI agent, not a website chat widget. It answers on voice, SMS, email, and WhatsApp, pulls order and product context, and takes actions like sending tracking or starting a return, instead of only posting canned replies in a chat box.

What can it handle on its own?

Tier-1 e-commerce support: order status (WISMO), returns and exchanges, sizing and product questions, availability, and basic account questions. You decide what it handles itself and what it escalates.

Does it replace my support team?

No. It handles the repetitive volume so your team focuses on the hard, high-value cases. Everything it can't resolve is escalated with a full transcript and summary, so humans don't repeat the back-and-forth.

Which channels does it cover?

Voice, SMS, email, and WhatsApp, in one agent. Customers reach you the way they prefer, and the answers stay consistent across all three.

Does it work with Shopify and WooCommerce?

Yes. Callsy connects to Shopify and WooCommerce, plus tools like Klaviyo and Omnisend, so it answers with real order and product context rather than generic replies.

How is this different from a support chat bot?

Channel and economics. Chat bots deflect text tickets, which are already your cheaper channel. Phone support is where cost scales with headcount, because a person can only take one call at a time. Callsy works the voice line as well as text, which is the expensive queue most support automation never touches.

How much can AI reduce our support costs?

It depends on how concentrated your volume is, and you can model it from your own data rather than a vendor claim. Take the share of contacts that are repeat questions, which on most support lines is the majority, and multiply by your loaded cost per contact for that channel. Treat that as the ceiling rather than the expectation, since some of those still need a human.

Does it cover calls outside business hours?

Yes, and that is often where it pays for itself first. Evenings, weekends, and holidays are when calls go unanswered entirely and when covering them with staff costs the most. The agent covers those hours at the same flat cost as any other.

Meet the founders

Built by founders, not a committee.

We're Arunas and Laimonas. We started Callsy because every D2C founder we talked to was losing revenue at checkout, and email recovery had plateaued. Voice was the obvious answer. AI finally made the unit economics work. If you're in the same spot, let's talk.
