TL;DR

- Shopify context drove our move: SleekFlow syncs customers, orders and abandoned carts into every chat.
- Clear ownership mattered as much as automation, and the Inbound Agent escalates by sentiment, topic or task completion.

We moved our small business from Manychat to SleekFlow because product data, customer conversations and sales follow-ups needed one home. SleekFlow is the best overall for sales, marketing and support in our retail workflow. Manychat remains a capable option for social messaging automation.
Why Our Priorities Shifted From Enquiries To Sales
Our shoppers discover a product on Instagram, ask about it on WhatsApp and return later with a delivery question. Each step depends on the one before it.
Starting conversations was enough when most of our work was answering common questions. Helping customers decide, buy and get support now sets our needs. We began judging platforms by the whole conversation, not the opening reply.
1. We Wanted Shopify Information Inside The Conversation
SleekFlow syncs customers, orders and abandoned carts from Shopify, so agents see purchase context during a chat. Agents share products from the Inbox with a template that shows the product name and price. They send payment links from the chat, using Shopify checkout or Stripe as set in the integration’s Payment tab.
The AI agent uses the store’s customer, order and cart data to answer common questions.Setup takes four steps: connect Shopify, choose a sales, support or marketing use case, install the app and confirm.
Shopify remains the source of truth, because the sync runs from Shopify to SleekFlow. Teams can import past customers and orders from the Data sync tab. We still verify variants, permissions and payment settings before relying on the connection.
A second benefit appears after checkout. A customer who asks about an existing purchase meets an agent who already sees the order, so the reply starts with facts instead of questions. That continuity replaced the separate lookups our team used before.
2. We Needed Clear Ownership When The Ai Agent Handed Over
Teams decide what makes SleekFlow’s Inbound Agent step back: a change in sentiment, a specific topic or a finished task. The person who takes over gets a full summary, so the customer doesn’t start again, and AI chat summaries give colleagues quick context in the Inbox. Several agents log into one account while each contact keeps a clear owner.
Busy periods test ownership hardest. A colleague who takes over should see the customer’s question and the next action at a glance. Our rule is simple: someone owns unresolved enquiries, and someone reviews exceptions. The platform supports that rule, while management defines it.
Manychat also offers live chat, and agents can pause automation to take over. Its Pro plan includes 3 team members and Premium includes unlimited members. SleekFlow Pro includes 10 seats, which suited our growing team.
3. We Wanted Ai To Support Buying Decisions Responsibly
SleekFlow’s AI agents answer questions, qualify enquiries and hand conversations to people. Playbooks control how the agent acts and which tools it calls, and reasoning traces show what knowledge it used for each answer. We set firm limits. An automated reply never invents a discount, promises an unconfirmed delivery date or approves a returned exception.
The NIST AI Risk Management Framework supports testing answers and reviewing failures throughout use. Manychat’s AI features, including Intention Recognition and AI Step, sit on its Pro and Premium plans. We chose the platform whose AI fitted our retail workflow.
4. We Wanted Follow-Ups That Reflect The Customer’s Situation
SleekFlow’s Flow Builder triggers workflows from Shopify events. Its ready-made templates include abandoned cart recovery, order updates, post-delivery feedback, post-purchase upsells, new-customer follow-up and loyalty invitations. Contacts can be labelled automatically from past interactions and purchases, and broadcasts can target those labels. A shopper waiting for an answer, a shopper comparing products and a repeat buyer each receive a different message.
Permission stays our responsibility on any platform. Under the WhatsApp policy, a business may message only people who have opted in. We also set stopping conditions for every sequence and review each campaign’s open and reply rates. SleekFlow’s broadcast analytics report both metrics and export to CSV, so our team checks what customers welcome.
5. We Wanted Sales And Support To Share The Same Priorities
SleekFlow brings WhatsApp, Instagram, Messenger and other channels into one workspace with customer details and custom fields. Sales and support colleagues see the same history after payment, when a buyer returns with a question. A delivery query goes to support, while a product recommendation draws on sales knowledge, and both appear in one thread.
In a SleekFlow customer story, Brazilian coffee retailer Coffee ++, which uses the Shopify integration, draws 70% of its CRM strategy revenue from WhatsApp.
SleekFlow serves 7,000+ businesses across 70+ countries, according to the company, and its Trust Center lists ISO/IEC 27001 and ISO/IEC 42001 certifications and a SOC 2 Type II attestation. G2 reviewers rate it 4.6 out of 5 from 205 reviews, and Trustpilot shows 4.5 from 55.
Where Manychat Still Fits
Manychat serves teams that start with social messaging. Its free plan covers up to 1,000 contacts, and Pro starts at US$15 per month, which keeps entry costs low. It added WhatsApp automation in 2022, according to a GlobeNewswire release.
A business that mainly captures Instagram and Messenger enquiries may need little beyond that. G2 reviewers rate Manychat 4.5 out of 5 from 165 reviews. Our needs moved toward commerce data, so we chose differently.
Both platforms reward careful setup. Clean product data, tidy contact fields and trained colleagues matter more than any single feature. Whichever tool a team picks, a monthly review of unresolved enquiries keeps the experience consistent as products and policies change.

What We Checked Before Moving Our Whatsapp Setup
We tested the move with ordinary customer situations before we disconnected anything. A product enquiry, an existing-order question, an uncertain AI answer and a request for a person gave a clearer picture than a polished demonstration.
- Number: confirm the supported migration route and required access with both providers
- Data: review contacts, permissions and workflows, since not every setting transfers automatically
- Budget: add the subscription, contact allowances, seats and Meta’s fees; Meta charges service messages after 1,000 free per number each month
- Ownership: name who maintains the knowledge base and store policies
How We Phased The Switch
A phased rollout limited risk for our small team. We ran the new setup beside the old one before moving customers.
- Connect Shopify and import past customers and orders from the Data sync tab.
- Load product and policy articles into the AI agent, and set its limits.
- Enable one recommended flow, such as abandoned cart recovery, after its WhatsApp template is approved.
- Route a small share of enquiries through the new inbox and review every escalation.
- Move the remaining conversations once answers and handovers pass our checks.
Before You Switch
SleekFlow is a strong choice for businesses that use Shopify and need an easier way to manage customer conversations. It brings together customer order information, a shared team inbox, AI-powered chatbots, and follow-up messaging in one platform.
These features make SleekFlow particularly useful for online stores that want to improve customer support and increase sales through messaging apps. Meanwhile, Manychat remains a practical and affordable option for smaller businesses that mainly need automated responses and social media messaging.
Test the full customer journey before committing. Run the same sample enquiries on both platforms, and choose the one your team can configure, afford and use every day.

How do you move a WhatsApp number to a new platform?
Moving a WhatsApp number starts with confirming the supported route with both providers. Export contacts and templates, test the new setup with sample enquiries and disconnect the old service only after those tests pass.
How much does a WhatsApp chatbot cost for a small business?
For a small business, the bill has two parts. Manychat starts free for up to 1,000 contacts, with Pro from US$15 a month, while SleekFlow’s Pro plan with Shopify sync and AI agents costs US$109 a month, billed yearly. Meta’s per-message fees come on top and depend on the message type and the customer’s country. SleekFlow’s plans and pricing also vary by country.

WhatsApp follow-up messages need customer opt-in. Meta’s policy allows businesses to message only people who gave permission, and businesses should honour requests to stop.
