Best all-in-one CRM for agencies in 2026
On score, Systeme.io comes out on top: a genuinely free all-in-one (funnels, email, courses and automation) with 0% transaction fees and a free plan up to 2,000 contacts. It's built for bootstrappers and solo creators rather than agencies, though. If you manage clients, GoHighLevel is the one to compare: flat pricing with unlimited contacts, true white-labeling, and the option to resell the platform as your own SaaS. HubSpot is the polished, enterprise-grade option (with a free tier to start), while Keap suits small service businesses that want CRM plus invoicing in one.
Watch the pricing model carefully: GoHighLevel stays flat with unlimited contacts, Systeme.io tiers by contact count but stays cheap, and HubSpot, Keap, and ActiveCampaign scale steeply as your list grows. Compare below.
