The best software stack for a marketing agency

What does a lead-gen agency actually need running for clients?

A marketing agency selling lead generation, funnels, websites, CRM and follow-up to small-business clients needs four things running at once, whether it is one consultant or a team of fifteen: a system that captures a lead and follows up with it automatically, a place to publish each client’s own website, a way to find and prove the SEO work a client is paying for, and somewhere to track which deliverable is due for which client this week. GoHighLevel covers the Run layer almost entirely: its CRM, funnel builder and email and SMS follow-up sit inside one subscription, and invoicing a client is built in too, so a separate payment tool never becomes a fifth line item on this stack. Client websites are still a separate purchase, in the Site layer, because GoHighLevel’s own page builder is built for funnels and landing pages, not the content-heavy business site a local search plan depends on. SE Ranking and ClickUp fill the Grow and Organize layers: one to find and report the SEO work clients are paying for, the other to keep a growing team from losing track of which client’s campaign is due Friday.

Where most advice gets this wrong

Most stack round-ups for agencies quote GoHighLevel at $97 a month and stop there, because that is the number on the pricing page. It is the right number for a solo consultant with one or two clients: Starter includes three sub-accounts, GoHighLevel’s term for a separate client workspace, plus unlimited users and contacts besides. It stops being the right number the moment a real agency signs a fourth client, because Starter’s three-sub-account cap is hard: the next plan up, Unlimited, costs $297 a month, three times Starter’s price, before a single extra text or email is added. A five-person agency running four or five retainer clients is already past that line, so the honest small-team number for this stack is $601 a month, not the solo figure most quick comparisons quote. The pricing page never states this as a warning; it only shows the cap in a features table most buyers skim past. Budget for Unlimited from the client that breaks three, not from the size of your team.

Why a cheaper website tool beats the familiar names here

Squarespace and Wix are the names most people reach for first: Squarespace’s Basic plan runs $25 a month and Wix’s Light plan runs $17 a month, its only published rate. Neither is built for an agency managing several client sites, though: both bill and log in per site, so five clients mean five separate subscriptions and five separate passwords with no shared agency view across them. Squarespace’s Basic plan can’t even add a third contributor without upgrading, and Wix doesn’t publish a month-to-month price for any tier, so comparing either against the picks below means comparing against an annual, paid-upfront number by default. Framer and Webflow both solve the multi-site problem with a workspace layer priced separately from each site: Framer keeps the workspace’s first editor free on every site, while Webflow’s Agency Workspace goes further and gives each client its own free reviewer seat, three per site, instead of a paid editor seat. Framer’s Basic site plan runs $15 a month, cheap enough that a fourth or fifth client site does not reshape the agency’s margin the way $39 a month per site on Webflow’s Premium plan can. Webflow earns its higher price on sites that outgrow a template: its CMS holds far more content, and its bandwidth scales to real traffic instead of Framer’s fixed 50 GB cap on the Basic plan. For a bare-bones five-page site for a plumber or a dentist, that headroom is not what the client is paying for.

Is SE Ranking really enough, or do you need Semrush too?

SE Ranking’s Core plan tracks up to ten projects for $129 a month, and because it prices by project rather than by keyword volume alone, ten client sites fit under one login before the agency needs to add a second manager seat. Semrush and Ahrefs both do more: Semrush’s toolkit stretches into content, social and paid-ads reporting an agency can resell as its own service, and Ahrefs built its own web crawler for backlink and keyword research, the reason a client would ask for it by name. Both cost more for the same client count, though. A five-person agency running the standard load for this stack pays $149 a month on SE Ranking against $379 on Semrush and $309 on Ahrefs, for SEO depth neither the local dentist nor the plumber client is likely to ask about; SE Ranking and Semrush update tracked keywords daily, while Ahrefs updates weekly on every plan. The honest reason to pay more is a specific client need, backlinks, content briefs, ad intelligence, not a bigger name on the login screen.

What do you actually buy in month one, and what waits?

Start with GoHighLevel’s Starter plan, Framer’s Basic site plan, SE Ranking’s Core plan and ClickUp’s Unlimited plan: that combination runs a single consultant’s whole client operation for $257.51 a month. The first upgrade to plan for, not to buy yet, is GoHighLevel’s Unlimited plan, and the trigger is a fourth client, not a fixed date on a calendar. Framer is the one exception worth timing rather than waiting on: its Basic plan is fixed with no pay-as-you-go option, so the moment a client’s site needs a third content collection or more than thirty pages, the honest move is straight to Pro rather than trying to make Basic stretch. The next upgrade is ClickUp’s Business plan, worth it once Dashboards, Timeline and Workload views are something the team opens every day rather than a nice-to-have; Unlimited’s own 100-use caps on those views make that decision for you once they run out. Site and SEO spending then scale the other way, per client rather than per team member, so the real planning question before signing a sixth or tenth client is whether that client’s retainer covers its own Framer site and its own SE Ranking project, not whether the agency’s overall software budget feels big enough yet.
