SleekFlow is a WhatsApp platform built for sales and commerce: broadcasts, flows, Instagram and Messenger in one inbox, and tools for selling over chat. Teams go looking for a SleekFlow alternative when the job is customer service rather than selling, when three seats on the entry plan isn't enough, when customers also email and call, or when email and VoIP are still labelled "coming soon" and they need them now.
This guide compares ten alternatives on the things that decide a service team's bill and workflow: users included, phone, how AI is charged, what WhatsApp messages cost, and which markets each vendor prices for. Cue publishes it and is one of the ten; the Cue entry says who it suits and who should look elsewhere.
Why teams move off SleekFlow
Four reasons come up, and none of them is that SleekFlow is a bad product.
Seats. Essential includes three seats; Pro and Premium include ten, with extra seats at $15 a month on Essential and $25 on Pro and Premium. A service team that grows past ten pays per head.
Channels still coming. SleekFlow's UK pricing page still labels email and VoIP as coming soon in its navigation, and says VoIP number hosting isn't available in the UK at the moment (5 November 2026). A service team whose customers email and call needs both today.
Sales-shaped, not service-shaped. Commerce features, abandoned-cart messages and broadcasts are the strength. Routing, assignment rules and reporting for an inbound service queue are where teams look elsewhere.
Contacts and users both metered. Essential and Pro include 500 monthly active contacts and Premium 1,000, with extra contacts at $20 per 100 on top of per-seat charges. Two meters make the bill harder to predict than one.

The column that decides most SleekFlow switches is users included. If your reason for leaving is the seat cap, price each option at the number of people who need the WhatsApp number, not at the headline plan.
If your team has outgrown three seats
Every Cue plan has unlimited seats, with WhatsApp, phone, email, web chat and Messenger in one inbox, from £249 or R4,500 a month. Book a demo or see pricing in pounds or rand.
Cue vs SleekFlow
Both run WhatsApp on the WhatsApp Business Platform with a shared inbox, templates and broadcasts. The difference is what the platform is for. SleekFlow is built around selling: commerce catalogues, flows that nudge a sale, Instagram and Messenger for marketing. Cue is built around service: WhatsApp, phone, email, web chat and Messenger on one contact record, routing by Flows, AI Agents answering routine questions, and unlimited seats so a whole service team can work the queue.
If you sell over chat and your team is small, SleekFlow is the closer fit. If customers come to you with questions, orders to chase and calls to make, and more than ten people need to see the inbox, Cue is.
1. Cue
Cue brings WhatsApp, phone, email, web chat and Facebook Messenger into one inbox. Every conversation sits on one contact record, so an agent answering a call sees the WhatsApp thread, and the person picking up tomorrow sees what was promised today.
What it does well
WhatsApp for service. A shared inbox on the WhatsApp Business Platform with Broadcasts and templates, assignment, notes and tags. Cue is a badged Meta Business Partner.
Phone in the same inbox. Cue Phone is included on every plan: calls matched to the contact, held, transferred, recorded and transcribed, with one-to-one outbound from a conversation. Phone Flows route callers by keypad menu from the Automate plan. Calls are answered by your team.
Flows and AI Agents. The Flows builder routes by the customer's answer, time of day or stored data; AI Agents on Automate and above answer routine questions on WhatsApp, email, web chat and Messenger from content you approve. Payflex resolves 82% of customer queries with Cue AI on its digital channels.
Unlimited seats. Every plan, no per-user charge.
UK and South African pricing. Published in pounds and rand, with offices in Chester and Cape Town.
Pricing: Connect £249, Automate £499 and Scale £699 a month at 1,500 monthly active contacts, excluding VAT, on a 12-month contract. Connect carries a one-off £249 onboarding fee; onboarding is free from Automate. WhatsApp messages are £0.10 marketing, £0.05 utility, £0.05 authentication and £0.02 service, with 1,000 free service messages a month per number. Full details on the pricing page.
Proof: Hollard saw a fivefold increase in survey responses after moving surveys from SMS to WhatsApp. On G2, a digital support specialist at Axxess, a South African internet provider, describes WhatsApp, the channel their customers prefer, as easy for agents and team leads to manage in Cue (review dated 9 September 2026). Cue is rated 4.9 out of 5 on G2 from 32 reviews (5 November 2026).
Watch out for: No Instagram or TikTok. Cue Phone has no voicemail, dialler or AI answering. AI Agents and the chatbot builder aren't on Connect. Cue isn't a commerce or catalogue tool; if selling over chat is the job, SleekFlow or DelightChat fit better.
2. respond.io
respond.io is a conversation management platform for teams handling a high volume of messages on WhatsApp, Messenger, Instagram, Telegram and other apps, with email alongside.
What it does well: Routing by need, workflows that automate follow-ups and data capture, broadcasts, CRM and ecommerce integrations, and AI agents on a published credit model. respond.io advertises VoIP and WhatsApp Calling, and states it doesn't add a markup to Meta's WhatsApp charges.
Pricing: Starter $79 a month annually ($99 monthly) with 5 users and unlimited monthly active contacts; Growth $159 ($199) with 10 users and 1,000 contacts; Advanced $279 ($349) with 10 users and 1,000 contacts. Extra users $12, $20 or $24 a month by plan on annual billing; extra contacts $12 or $15 per 100. Checked 5 November 2026.
Best for: Teams on many messaging apps with sales-style orchestration at volume.
Watch out for: USD pricing on contacts and users, so both meters move. We compare the two in respond.io vs Cue.
3. Wati
Wati is a WhatsApp marketing and sales platform with a low entry price, built around campaigns, with Instagram, Facebook and TikTok alongside and WhatsApp Business Calling.
What it does well: Broadcasts, a chatbot builder, a catalogue and a simple inbox, at a price small teams can start on.
Pricing: Wati shows prices by region. Checked 6 November 2026, its UK page showed Growth £49, Pro £99 and Business £229 a month billed annually (£59, £129 and £289 billed monthly), with extra users at £32 (Pro) and £74 (Business). Growth includes three users with no extra users allowed; Pro and Business include five. WhatsApp messages are on Wati's own rate card.
Best for: WhatsApp campaigns for a small team.
Watch out for: The same seat cap that sends teams away from SleekFlow. Our Wati alternatives guide compares the options.
4. Trengo
Trengo is a shared inbox for email, WhatsApp, Instagram, Facebook and a website widget, with Flowbots, AI tools and Trengo Voice.
What it does well: Channel breadth on every plan, team assignment and notes, no-code Flowbots, and AI voice on the Trengo Voice add-on.

5. Front
Front is an email-style shared inbox with WhatsApp available on its Professional and Enterprise plans.
What it does well: Collaboration in the thread, rules and routing, a wide integration catalogue, and reporting by team and channel.

Best for: Email-led teams that want WhatsApp alongside.
Watch out for: Per-seat pricing and the 20% WhatsApp fee. See Front vs Cue.
6. Crisp
Crisp puts website chat, email, Messenger and WhatsApp into one inbox with a chatbot builder and a knowledge base, priced per workspace rather than per seat.
What it does well: A flat workspace price with seats bundled, and chat plus messaging apps at a low entry point.
Pricing: Free for two seats; Mini $45 a month for four seats, Essentials $95 for ten, Plus $295 for twenty or more with extra agents at $10. WhatsApp is from Essentials; AI runs on a dollar credit allowance by plan ($5 Mini, $25 Essentials, $75 Plus). Checked 5 November 2026.

Checked 5 November 2026.
Best for: Small teams that want WhatsApp in a cheap shared inbox.
Watch out for: WhatsApp needs Premium, and routing and automation are lighter than a service platform.
8. Hiver Omni
Hiver Omni is Hiver's multi-channel product for teams that already work in Gmail and want WhatsApp, chat and voice alongside it.
What it does well: Shared inbox management inside Gmail, assignment and collision alerts, and WhatsApp and live chat in the same workspace. Voice is an add-on.

Best for: Gmail-based teams that don't want a new interface.

9. DelightChat

Best for: Small teams that want the widest messaging-app coverage cheaply.
Watch out for: No phone or email, and per-user pricing with channel add-ons.
SleekFlow alternatives in South Africa
South African teams ask two extra questions: what does it cost in rand, and is anyone local?
Cue is priced in rand on its South African pricing page: Connect R4,500, Automate R8,800 and Scale R13,300 a month at 1,500 monthly active contacts, with WhatsApp messages at R0.70 marketing, R0.25 utility, R0.16 authentication and R0.16 service. Cue has an office in Cape Town as well as Chester, and the free support plan runs on weekday hours with paid tiers above it. Hollard, Payflex and Pace Car Rental are South African customers whose results are published.
ChatInc is the local WhatsApp provider most often shortlisted alongside Cue; it doesn't publish prices we could verify, so ask for a quote. For a fuller SA list, see our comparison of WhatsApp Business solution providers in South Africa.
Moving your WhatsApp number from SleekFlow
You can move a WhatsApp Business Platform number from one provider to another. Tell the current provider you're leaving, have two-step verification switched off on the number, and let the new provider register it. Your number and your approved message templates move with you to Cue. Ask both providers in writing about timing before you set a date, and export your conversation history from SleekFlow first, because it lives in SleekFlow's software rather than on the number. Keep SleekFlow running until the number is live and answering in the new platform.
How to choose
Is the job selling or serving? Commerce tools favour SleekFlow, DelightChat and Wati. Service favours Cue, respond.io and Trengo.
How many people need the number? Count everyone who should see a conversation, including the people who don't answer. Price each option at that number.
Do customers also call and email? If yes, shortlist platforms where phone and email are live now, not coming soon: Cue includes both; respond.io advertises VoIP; Trengo and Hiver sell voice as add-ons.
Which currency and which support hours? UK and SA teams should check for GBP or ZAR pricing and local support before comparing headline prices.
How is AI charged? Per resolution, per conversation, by credits or not offered. Model it on your real volume.
