Why CresaWhat changes for your business

Customers expect an answer in minutes, on the app they already use. Cresa gives every business an always-on team member that knows your products, prices and policies, and a calm inbox where your people handle the rest.

Reply in seconds, 24/7

No more “sorry for the late reply”. Questions about prices, stock, timings and delivery are answered the moment they arrive, even at 2 a.m.

Never miss a lead

Every enquiry from every channel is captured, qualified and followed up, then lands in your sales pipeline instead of getting lost in a phone.

Grow without hiring

Let the agent take the repetitive questions so your team spends its time on the conversations that close sales.

One view of every customer

WhatsApp, Instagram, Facebook, web chat and email history in one profile, so anyone on your team can pick up where the last person left off.

Everything you need to win every conversation

features

AI customer service & sales agent

Trained on your documents, FAQs and price lists. It answers questions, recommends products, takes orders, books appointments, updates your CRM and follows up, in your brand's tone.

Shared team inbox

All channels in one inbox. Assign chats, add internal notes, tag and resolve, with roles for admins, managers and agents.

Official WhatsApp Business API

Connect your number through Meta's official signup. No unofficial tools that put your number at risk, and the 24-hour window is tracked for you.

Knowledge base

Upload PDFs, Word files, FAQs, price lists and web pages. Cresa shows you the questions it couldn't answer, so it gets smarter every week.

Appointment booking

Customers book, reschedule and cancel in chat. Syncs with Google Calendar and Microsoft 365 and sends reminders.

WhatsApp broadcasts & marketing

Send approved templates with images, flyers or video to segments of opted-in customers, and track delivered and read rates.

Sales CRM & pipelines

Turn chats into deals with drag-and-drop pipelines, contacts, groups and CSV import. Every deal stays linked to the conversation it came from, so nothing slips.

Reads photos, PDFs & voice notes

Customers send a screenshot, a receipt or a voice message. Cresa understands it and answers.

Automations & follow-ups

Welcome messages, routing, escalation and “just checking in” follow-ups that run on their own.

Shopify & WooCommerce

Product search, stock, prices and order status inside the chat.

Speaks your customers' language

English, Spanish, French, German, Arabic, Portuguese and more.

Analytics & intent insights

ai agent

An agent that works like your best employee. And knows when to call you.

Cresa doesn't just chat. It does the work: checks stock, quotes prices, books the slot, creates the lead and reminds the customer tomorrow. Anything that needs a decision, like a discount, a refund or an exception, comes to you first.

  • Training mode. Review and approve every reply until you trust it.
  • Human hand-over. Passes the chat to your team with a summary when a customer asks for a person.
  • Your rules. Switch the AI off for any chat, channel or customer, any time.
  • Learns from you. The corrections your team makes shape future replies.

WhatsApp message fees are between your business and Meta. Meta charges per delivered template message (marketing, utility and authentication) directly to the payment method in your own Meta Business portfolio. Cresa never bills, resells or marks up WhatsApp messages, and they are not part of your Cresa subscription. Replies inside the 24-hour customer service window are free.

FAQEverything people ask before signing up
01What is Cresa?+

Cresa is an omnichannel AI customer service and sales platform. It brings WhatsApp, Instagram and Facebook DMs and comments, website chat, email, Google reviews, LinkedIn, YouTube and TikTok into one shared inbox, with one AI agent that answers customers from your own documents, books appointments, captures leads and follows up.

02How does the AI agent learn about my business?+

You upload what you already have: price lists, menus, brochures, policies, FAQs or web pages. The agent answers from that material in your tone and language, and Cresa shows you the questions it couldn't answer so you can fill the gaps.

03Can I use Cresa with my existing WhatsApp number?+

Yes. You connect your number through Meta's official WhatsApp Business Platform signup inside Cresa, which takes a few minutes. If the number is currently on the WhatsApp Business app, it is migrated to the API, which Meta supports.

04Will the AI say something wrong to my customers?+

You stay in control. Start in training mode, where every reply waits for your approval. The agent answers only from your material, asks a person before discounts, refunds or exceptions, and hands over to your team when it isn't sure. You can switch it off for any chat.

05Which channels does Cresa support?+

WhatsApp Business API, Instagram (DMs, comments, story replies and mentions) and Facebook (Messenger and Page comments) on every plan. From the Professional plan: a website live chat widget; email (Gmail, Google Workspace, Outlook, Yahoo or any IMAP mailbox); Google Business Profile reviews; LinkedIn Company Page comments; YouTube comments; and TikTok comments (beta). All of them share one inbox and one AI agent.

06Can Cresa understand images, PDFs and voice notes?+

Yes. When a customer sends a photo, a screenshot, a PDF, a short video or a voice note, Cresa reads it and replies to what it contains, just like a person would.

07What languages does the AI agent speak?+

English, Spanish, French, German, Italian, Portuguese, Arabic, Chinese, Japanese, Urdu and more. You choose which languages your workspace replies in.

08Can Cresa book appointments and send reminders?+

Yes. Customers can book, reschedule or cancel in the chat. Cresa checks availability, syncs with Google Calendar or Microsoft 365, and sends reminders before the appointment.

09Does Cresa work with Shopify and WooCommerce?+

Yes, on the Professional plan. The agent can search your products, check stock and prices and answer order status questions inside the conversation.

10How much does Cresa cost?+

Starter is $39 a month, Professional $99 and Business $249, or less when billed yearly. Extra team members are $15 a month each, and Enterprise is custom. Every plan includes a monthly allowance of AI credits, and every workspace starts with a 14-day free trial with all features unlocked.

11Who pays for WhatsApp messages?+

Meta charges your business directly for delivered template messages, through the payment method in your Meta Business portfolio. Cresa never bills or marks up WhatsApp messages. Replies inside the 24-hour customer service window are free. Cresa shows an estimate of this month's Meta charges on your billing page.

12Which businesses is Cresa for?+

Any business that talks to customers on messaging apps: retail and e-commerce, restaurants, clinics, schools, real estate, travel, salons, hotels, wholesalers, automotive, solar and home services, and financial and professional services, from a single shop to multi-branch teams.

13Is my data safe?+

Your data is used only to run your workspace. AI providers receive only what a task needs, and your messages are not used to train our own models. You can ask us to delete your data at any time.

14What happens when the free trial ends?+

Pick a plan to keep going. If you don't, AI replies pause and new work is blocked, but you can still log in and see everything, and carry on where you left off when you subscribe.
