How to Collab on Instagram: Collab Posts for Brands, Step by Step

A collab post is the simplest way for two accounts to share one post: a brand and a creator, two partner shops, an agency and its client. Most guides stop at the button. Many also quote a limit of 1, 3 or 5 collaborators without saying where the number came from.

This guide gives you the steps with Meta's current documentation behind them. It also covers what happens after you publish: how the invite is accepted, who can invite whom, how to undo a collab, and how to schedule one when Instagram's scheduler says no. If you are still setting up your profile, start with our Instagram for business guide.

What an Instagram collab post is

A collab is a post with more than one author. According to the Instagram Help Center (checked November 2026), once an invited account accepts:

• its name is added to the post, next to yours;
• the post is shared with its followers;
• the post shows up on its profile;
• it can see all the likes and comments on the post.

Collab or tag?

People mix these up, so here is the difference in one table, also from the Instagram Help Center.

	Tag	Collab
Name on the post	In the tag only	Listed as an author
Reaches the other account's followers	No	Yes
Appears on the other account's profile	In its tagged posts, unless it approves tags manually	Yes
Needs the other account to accept	No	Yes

Tagging still has its place. It works on photos, Reels and carousels, before or after you publish, and a private account can tag only its followers (Instagram Help Center, checked November 2026). Use a tag to credit someone. Use a collab when both accounts should own the post.

How to collab on Instagram, step by step

You set up the collab before you publish. The Help Center lists these steps:

1. Open the Instagram app on your phone or tablet. The feature is not available on a computer.
2. Create your post or Reel as usual: media, edits, caption.
3. On the final screen, before sharing, tap Tag people.
4. Tap Invite collaborator.
5. Search for the account and select it. Repeat for each collaborator.
6. Tap Done, then publish.

Three limits to know before you plan:

• Up to 5 collaborators per post in the app (Instagram Help Center, checked November 2026). The same number appears in Instagram's Reels tips (Instagram blog, June 2024). Guides that say 1 or 3 are out of date for the app.
• No Stories. You cannot add collaborators to a Story.
• Plan it before you post. The Help Center shows how to remove a collaborator after publishing. It does not show how to add one, so treat the invite as a pre-publish step.

How to accept a collab invite on Instagram

The invited account gets a message. To accept, it opens Messages, taps the invite, taps Review, then Accept.

Until it accepts, the post lives only on your profile. After it accepts, the four changes listed in the first section apply.

If you work with a creator or a partner brand, tell them the invite is coming and when. An invite sitting unread in the inbox means the post reaches only your own audience in its first hours.

Public and private accounts: who can invite whom

The Help Center sets these rules:

• A public account can invite public or private accounts.
• A private account can invite only accounts that follow it.
• If a private account's post is accepted by a public collaborator, the post becomes public through that collaborator.

The last point matters for small businesses that keep a private account for a reason. Check who you are inviting before you publish.

How to leave, remove or delete a collab

A collab can end in four ways, all from the Instagram Help Center:

• The collaborator leaves. It opens the post, taps Options, then Stop sharing. It can do this at any time.
• The creator removes a collaborator. You open the post, tap Options, Edit, Tag people, then remove the account. You can do this at any time too.
• The creator deletes the post. Only the original creator can delete a collab post, and it disappears from both profiles.
• Someone blocks the other. A block from either side ends the collab. The post stays on the creator's profile.

Put this in writing with your partner before the post goes out. If a partnership ends badly, the person who created the post holds the delete button.

Instagram collab ideas for brands

The businesses below are fictional. Each idea is a format, not a promise of reach: a collab puts the post in front of both audiences, and what they do with it depends on the post.

Brand and creator

A fictional skincare shop in Austin sends its new sunscreen to a local runner who posts about training. The runner creates a Reel of her morning route with the product, and invites the shop as a collaborator. Her followers see a real use case, and the shop's followers see a face they may not know yet.

Two partner brands

A fictional coffee roaster and a bakery on the same street publish one carousel: "Our 3 favorite pairings this fall." Each slide shows one pastry and one roast. A carousel is easy to share between brands because each brand can own some of the slides. For structure, see how to make Instagram carousels that get saved.

Agency and client

An agency publishes a case study from its own account and invites the client as a collaborator, so the result shows up on both profiles. Get the post approved before you send the invite, since the client's name goes on it. A client approval process saves you from deleting and reposting.

Event and supplier

A fictional wedding planner in Charlotte posts a recap of a reception and invites the florist and the caterer. Three businesses, one post, and each one can show it on its own profile. With 2 collaborators, it fits both the app limit and the API limit.

How to schedule an Instagram collab post

Scheduling is where collabs get stuck. Instagram's built-in scheduler does not support collabs. The Help Center page on scheduled posts (checked November 2026) says: "Features like product tagging, collaborative posts, sponsored posts and fundraisers aren't compatible with scheduled content at this time."

So in the app, a collab post has to be published live, by hand, at the moment you want it out.

Meta's API does allow it. The IG User Media reference (Meta for Developers, checked November 2026) accepts a list of up to 3 usernames as collaborators, for feed images, Reels and carousels. Stories are excluded there too. That is why tools that publish through the API, Zynta Flow included, cap a collab at 3 accounts while the app allows 5. The limit comes from Meta, not from the tool.

Collab posts in Zynta Flow

When you schedule a post to Instagram and LinkedIn in Zynta Flow, the composer shows an Instagram only card whenever the post goes to Instagram. It has two fields:

• Collaborators (collab). Type up to 3 usernames, separated by commas, spaces or line breaks; the @ is optional. The help text explains that it invites public accounts as co-authors, and that the post appears on their feed too once they accept.
• Tag people in the photo. Shown when the post has an image. For each tag, pick the slide and type the username, up to 20 public accounts per image. The tag goes at the center of the slide image; you cannot move it. Up to 20 per image is Zynta Flow's own limit.

The post goes out at the scheduled time whether or not the invite has been accepted. It shows on the collaborator's profile only after they accept.

A few details to plan around:

• Collaborators work on single images, carousels and Reels. Reels do not take photo tags in Zynta Flow, and Stories take neither collaborators nor tags.
• If you reopen the post in the calendar to edit it, the collaborators and tags are still there.
• Through the API, data for a co-authored post is available only to the account that published it (Meta for Developers, Instagram Platform overview, checked November 2026). Agree with your partner on who publishes and who shares the results.

If you design the post in Zynta Flow too, the Instagram carousel maker builds the slides on your brand kit before you schedule them.

Frequently asked questions

How many collaborators can you add to an Instagram post?

Up to 5 in the Instagram app, according to the Instagram Help Center. Tools that schedule through Meta's API, such as Zynta Flow, can add up to 3, because that is the API limit.

Can a private account do a collab on Instagram?

Yes. A private account can invite only accounts that follow it. A public account can invite public or private accounts, and if a public account accepts a private account's invite, the post becomes public through it.

How do I accept a collab invite on Instagram?

Open Messages, tap the invite, tap Review, then Accept. Your name is added to the post, and it appears on your profile and goes to your followers.

What is the difference between a collab and a tag on Instagram?

A tag credits someone, but it does not send the post to their followers or list them as an author. A collab does both, once the invited account accepts.

Can I remove a collaborator after posting?

Yes. The creator can open the post, tap Options, Edit, Tag people, and remove the account. The collaborator can also leave at any time with Stop sharing.

Can you schedule a collab post on Instagram?

Not with Instagram's own scheduler, which does not support collaborative posts at this time. A tool that publishes through Meta's API, such as Zynta Flow, can schedule it with up to 3 collaborators.

Can you do a collab on Instagram Stories?

No. Collaborators work on feed posts, carousels and Reels, not on Stories, both in the app and through the API.
