Every agency running client social hits the same moment. A post is written, the graphic’s built, and now somebody who isn’t you needs to see it before it goes live. How that approval actually happens, who gets a link, whether it costs a login, whether it can go through two people rather than one, is one of those features you don’t think about until the day a client insists on it.
Vista Social
Single-step approval on the Professional tier, multi-step (two rounds of sign-off) on Advanced. The part worth knowing: external client approval runs through a no-login Shared Calendar link, so the client reviewing and approving a post doesn’t consume one of your paid seats. That matters more than it sounds, because most competitors that do offer external approval either charge for the reviewer’s access or restrict how many external approvers you can add.
How the others handle it
Metricool’s Advanced tier (from $53/month) supports unlimited users and lets external reviewers approve straight from an email link, but there’s no sequential staging, one approval and it’s done, no way to route it through a second person after the first sign-off.
Sprout Social builds arguably the most complete approval workflow of the six, but it’s gated behind the Advanced tier at $399 per seat per month, and even then External Approvers is capped at 3 people. It’s a genuinely good system if the budget supports it.
Hootsuite’s approvals also sit on its Advanced tier, $399 per user per month, the same price point as Sprout’s but without the multi-approver cap being clearly documented either way.
Buffer includes approvals on its Team plan at $10 per channel per month, with unlimited members, which is the most affordable route to a working approval flow of the six if the rest of Buffer’s feature set fits what you need.
Later’s Growth tier ($37.50/month annual) has both internal and external approvals built in, at a price point closer to Metricool’s than Sprout’s or Hootsuite’s.
What this actually means choosing between them
If the requirement is simply “a client needs to sign off before anything goes live,” several of these do that adequately. Where Vista Social and Metricool pull ahead is the no-login, no-extra-seat external review, which matters specifically when you’re managing client accounts rather than one internal brand, since you don’t want to be paying per client reviewer or asking them to create an account just to approve a caption.

Where Vista Social doesn’t win
Sprout’s approval workflow is more configurable if you genuinely need it, multiple sequential stages, granular permissions per role, and it’s the one built with larger internal teams in mind rather than external client review specifically. If that’s the actual requirement, the $399/seat price might still be worth it, Vista Social’s two-step ceiling won’t stretch to a five-person internal sign-off chain.
The motorsport angle
A driver’s management team is rarely one person. A parent handling the accounts, a manager handling sponsor relationships, sometimes the driver themselves wanting final say on anything with their name on it. A no-login approval link means the parent or manager can review and approve from their phone between sessions on a race weekend, without needing their own Vista Social account or remembering a password at a circuit with patchy signal. For a sponsor-facing post specifically, being able to get sign-off from someone in the team before it goes live, without a seat cost, is the difference between checking with them and just posting and hoping.
