“After I started using PostOnce, my results started snowballing.”
Social media management for agencies, minus the reposting.
Social media management for agencies shouldn’t mean uploading the same video to every app, for every client. Post each client’s Reel or TikTok once, where you already post it. Within 20 minutes, PostOnce publishes it to that client’s other accounts: TikTok, YouTube Shorts, Facebook, LinkedIn and more.

Your client’s Instagram Reel
You post here
One upload per client. Every platform they pay for.
You make the video once. Then you upload it for every app, for every client.
Clients want Instagram, TikTok, YouTube Shorts and Facebook, and the retainer rarely grows with the platform list. So the same video gets downloaded, re-uploaded and re-captioned on every app, for every client, behind a different login each time. It’s the part of the job no client sees and nobody pays for.
Without PostOnce
One client video, by hand
- 1Download
- 2Upload to TikTok
- 3Upload to Reels
- 4Upload to Shorts
- 5Fix each caption
…then again for the next client
- Download, re-upload and re-caption the same video on every app
- A password spreadsheet and 2FA codes for every client account
- Logging in and out, hoping you’re on the right client
- A new platform on the retainer means one more upload per post
With PostOnce
1 client Reel
- Post once per client, where you already post
- The same video reaches that client’s other accounts within 20 minutes
- Clients connect their own accounts from your invite link, without sharing passwords
- One workflow per client, named after the client
- Every post’s status in one place: posted, scheduled or failed
You sell strategy and content. The re-uploading shouldn’t be where your day goes.
A social media management tool for agencies: one workflow per client
Local business clients
Instagram → Facebook Page, TikTok, YouTube Shorts
Post the café’s or clinic’s Reel on Instagram. It also lands on their Facebook Page, TikTok and Shorts, so every platform on the retainer gets it.
B2B and personal-brand clients
Instagram or TikTok → LinkedIn, YouTube Shorts
Put a founder’s or firm’s short videos on their LinkedIn profile or company page and on Shorts, from the Reel you already posted.
A client just added a platform
Instagram → a new TikTok or Shorts account
Fill the new account from the client’s older Instagram posts on a publishing schedule you set, then keep it in sync with every new post.
Pinterest, Threads, X and Bluesky routes work too. Carousels and photo posts go everywhere except YouTube. See all crosspost routes →
We handle the reposting. You keep the client work.
PostOnce handles
- Publishing each client’s new posts to the accounts you choose
- Custom caption text per account, before or after the original
- Filters for what goes out: videos only, hashtag rules, no Trial Reels
- A client invite link, so accounts connect without passwords
- Posting through each platform’s official posting APIs
You still own
- Strategy, content and the creative
- Client approvals and the content calendar
- Reports and analytics for clients
- Comments, DMs and community management
- Your client relationships and your pricing
PostOnce isn’t an all-in-one agency suite. It has no approvals, reports, inbox or white label. It does the reposting, and it works next to whatever you already plan and schedule in.
Do scheduled posts get less reach?
We tested 40 YouTube channels before and after they started posting through PostOnce: no consistent drop in views.
We also grew our own app, How2Rizz, posting the same videos everywhere through PostOnce.
- TikTok followers
- ~15k
- TikTok
- Instagram followers
- ~10k
- YouTube followers
- ~5k
- YouTube
Each client post reaches their other accounts within
20 min
so you post once per client and move on to the next one.
And the typical PostOnce customer saw 98.5% of their posts go out successfully.

Compare all plans →Questions agencies and social media managers ask
How do I get into a client’s accounts without their password?
Send them your PostOnce invite link. They pick a platform and approve access on that platform’s own login screen, so you never handle their password or 2FA codes. The account then appears in your PostOnce. You can copy, regenerate or turn off the link at any time.
Is PostOnce a social media management tool for agencies, like Hootsuite or SocialPilot?
Not the all-in-one kind. Suites like Hootsuite, SocialPilot and Sendible bundle planning, approvals, reports and an inbox, and many charge by user or profile. PostOnce does one job: it publishes each client’s new post to their other accounts. You can keep your planner and let PostOnce handle the reposting. For scale: SocialPilot’s Ultimate plan is $200 a month for 50 accounts; PostOnce Pro covers 50 accounts for $69 and Agency covers 200 for $199.
Can I keep each client separate?
Each workflow sends one account’s posts only to the accounts you pick, so one client’s video never lands on another client’s accounts. Name each workflow after the client and you’ll see its posts and their status on its own page. All clients live in one PostOnce login; there are no separate client workspaces.
Does PostOnce do client approvals or reports?
No. There’s no approval flow, client-facing calendar, analytics report or white label. Keep the tools you use for those. PostOnce picks up the post once it’s live on the client’s main account, however you published it.
Will scheduled posts get less reach?
PostOnce posts through each platform’s official posting APIs, the same way schedulers do. In our test of 40 YouTube channels there was no consistent drop in views after they started posting through PostOnce. Reach problems usually come from account standing, not from how a video was uploaded.
Can I change the caption for each platform?
Yes. Each account in a workflow can add its own text before or after the original caption, like a client’s booking link on Facebook or hashtags on TikTok. You can also choose which posts go out: videos only, posts with or without certain hashtags, or no Trial Reels.
Does it post to Facebook Pages and LinkedIn company pages?
Yes. Connect the client’s Facebook Page and their LinkedIn profile or company page, then add them to that client’s workflow.
A client just added TikTok. Can we fill it with their older videos?
Yes. Turn on existing content in the workflow and PostOnce queues the client’s older posts to the new account on a publishing schedule you set. New posts keep flowing as usual.
Does it work for carousels and photo posts?
Yes. Carousels, slideshows and photo posts are supported as well as videos. YouTube only takes videos, so photo posts go to every platform except YouTube.
How many clients fit on a plan?
Plans count connected accounts, not clients or users. If each client has four accounts, Creator’s 15 covers three clients, Pro’s 50 covers twelve and Agency’s 200 covers fifty.
Can I cancel anytime?
Yes. The trial is 7 days with no credit card, and paid plans can be cancelled anytime.

Stop re-uploading the same video for every client.
Send your invite link, set up a workflow for one client, and watch their next post land on every account you choose.
