HL Pro Tools vs Extendly vs Growthable: White-Label GHL Support Compared (2026)

What do these three companies actually sell?

All three sell the same core promise — your GHL clients get support that looks like it comes from your agency — wrapped in three different products. HL Pro Tools is a support desk plus agency toolkit: branded 24/7 chat, tickets, and Zoom from the VIP tier up. Add a theme builder, a snapshot library, and 10+ weekly group coaching calls. Extendly is a support desk first: fully white-labeled live chat with an under-a-minute first-response claim, plus a separately sold snapshot store and per-client onboarding. Growthable is support plus labor: 24/7/365 branded chat and, at higher tiers, metered onboarding hours and a dedicated virtual assistant.

One entity note, because the name still confuses buyers. GHL Experts, once an independent support shop, was acquired by Extendly in January 2023. It now operates as coaching and education under that umbrella — if a roundup lists it as a fourth support vendor, the roundup is old.

What does each one cost in 2026?

Prices below were fetched from the vendors' own pricing pages on July 22, 2026. That's worth stating, because widely shared comparison pages still list HL Pro Tools' VIP at $297 (it's $397), Extendly's retired flat tiers, and discontinued Growthable price points. This market reprices often. Anything undated is wrong somewhere.

Reading the entry chart requires the units. Extendly's $299 covers 10 sub-accounts, and HL Pro Tools' $397 covers 10 clients. Growthable's $549 covers unlimited sub-accounts from day one, which undercuts both rivals once you pass roughly 20 accounts on Extendly's ladder ($399 for 20, $599 for 40). Software-only tiers exist below all of this: Extendly's $99 ExtendlyOS and HL Pro Tools' $197 Core ship the branded widget and knowledge base with no live agents behind them. And whichever you pick, platform usage still flows through GHL's wallet and rebilling system on top.

The chart carries a fourth data point for market context: GHL Ops, an hours-based build team rather than a branded help desk, publishes $480 a month for 40 build hours. Different product, same budget line.

Where HL Pro Tools, Extendly, and Growthable differ: support, onboarding, labor

Support claims first, with the caveat the vendors won't give you: the numbers measure different things. Extendly's headline is an under-1-minute first response — on live chat. HL Pro Tools publishes a 3.5-hour average — on tickets. Growthable's "1–2 minute" figure appears only in a customer testimonial, with no official SLA behind it. All three claim 24/7 coverage; HL Pro Tools specifies its span as US time zones plus GMT+10.

Onboarding is where agencies should focus, because it's the labor you'd otherwise do. HL Pro Tools runs unlimited group onboarding on VIP — a 13-week program clients attend — with true 1:1 calls reserved for Elite (five free per month). Extendly sells white-glove per-client onboarding: two one-hour Zoom calls, recorded and branded, with A2P, domain, and email setup in scope. The per-client price isn't published, so get it quoted in writing. Growthable meters it: five, eight, or ten hours a month by tier, with overage billed at $100, $80, or $50 an hour. Only Growthable sells ongoing build labor at all. The dedicated 20-hour-a-week VA in its Enterprise tier is the one offer that overlaps what an agency's own hire would do.

Also worth knowing what none of the entry tiers do: build your client funnels. Extendly excludes done-for-you work explicitly; support desks answer questions. Build capacity comes from your team, a VA tier, or a managed service.

The trust picture, with caveats

Review volume differs by an order of magnitude. Every number here is snippet-sourced — Trustpilot blocked our direct fetch, so treat them as approximate. HL Pro Tools shows a 4.7 TrustScore across 154 reviews, Growthable 4.5 across 26, Extendly 4.2 across 14. HL Pro Tools' volume lead is real signal; the other two sample sizes are too small to rank against each other. Extendly's own site claims a 95%+ satisfaction score across 331,000+ interactions — self-reported, no methodology published, so we list it without endorsing it.

In the one public head-to-head we found — a Facebook poll cited by an affiliate reviewer — Extendly led with 48% against HL Pro Tools' 32% and Growthable's 8%. A poll on an affiliate's audience is weak evidence. We include it because it's the only comparative sentiment data that exists, which itself tells you how young this market is.

HL Pro Tools vs Extendly vs Growthable: which fits your agency?

Under 10 clients and cost-sensitive: Extendly's $299 entry is the cheapest live desk, and per-client onboarding means you pay for exactly the clients you sign. Just get that unpublished onboarding price quoted first. Growing past 20 accounts, or allergic to per-account math: Growthable's unlimited-from-day-one Starter undercuts the ladders, and its hours-based onboarding scales predictably. Scaling on community and group onboarding: HL Pro Tools' VIP is built around exactly that. Its Elite tier's five monthly 1:1 onboardings plus four DFY A2P registrations map neatly onto an agency signing a handful of clients a month.

And the fourth option the three-way framing hides: if what you actually need is the platform built and run — not client questions answered — that's not a support desk's product. That's white-label fulfillment, and it's the work we do behind agencies: scoped builds, A2P, and management, without a per-seat ladder. New to the platform entirely?
