How to schedule TikTok, Instagram and Facebook posts from one place

Why the three networks should be treated as one job

TikTok, Instagram Reels and Facebook Reels all want the same thing: a vertical 9:16 clip, ideally 1080 × 1920, under a minute, with a caption that hooks in the first line. The production work is identical. What differs is the caption tone, the character limits and the platform-specific settings — and those are exactly the things a tool can vary for you while you keep making one clip.

The mistake most people make is the opposite: producing one clip and pasting the same caption on all three accounts within the same minute. Platforms are good at spotting that, and it is the most common reason cross-posted content underperforms.

Step 1: connect the accounts through the official logins

Any serious scheduling tool connects to TikTok, Instagram and Facebook through their own OAuth login — the same screen you see when you log into any app with those accounts. Your password stays with the platform, the tool receives a revocable token, and you can cut it off from the platform's settings at any time. If a tool ever asks you to type your Instagram password into its own form, close the tab.

A few requirements are worth knowing before you start. Instagram only allows publishing through its API from Business or Creator accounts — switching from a personal account takes a minute in Instagram's settings and changes nothing your followers can see. Facebook only publishes to Pages, never to personal profiles, and you need to be an Admin or Editor of the Page. TikTok shows a consent screen with several permissions; every one of them must be accepted or the connection silently fails.

• Instagram: Business or Creator account, linked to a Facebook Page.
• Facebook: a Page you administer, not your profile.
• TikTok: accept every permission on the consent screen.

Step 2: keep each business's accounts apart (optional)

If you run more than one business — or one business with separate audiences — you can group each one's accounts into a brand. It is optional: with a single business you do not need brands at all. Whenever you post a clip you tick the exact accounts it goes to, so a café's TikTok never receives a salon's clip by accident. Brands are also how you connect a second TikTok account: TikTok allows one account per brand, so a second account needs a second brand.

Step 3: make the clip, then post it now, later or as a series

In PostingClips a clip comes from one of three places: from an idea (AI generates the video; the price depends on the model and the length you pick), from our footage library (free), or from your own video (MP4, MOV or WebM). Every clip can be opened in the editor, where you trim it, add text, music, sound effects and transitions, and pick the format before posting.

Then there are three ways to send it out. The Post button sends one clip to the accounts you tick, right away or at a date and time. In the Calendar, Schedule several takes clips you already have and spreads them, in order, over the days and hours you choose, with a preview. And an automation (Automate) makes new clips on its own, from an idea, on the days and hours you set, and posts each one to the accounts you picked; automations start after your first purchase.

Step 4: let the captions and the timing differ

This is the part that makes cross-posting safe. Each account should get its own caption — same message, different wording, different hook, a different mix of hashtags — written in the platform's register: punchy for TikTok, warmer for Instagram, a little more explanatory for Facebook. And each post should go out a few minutes apart rather than in the same second.

PostingClips writes one caption per account with AI, in the language of the clip's idea, and staggers each following account by 8 to 20 minutes. If you prefer your own words, write one caption and it is used on every account, trimmed to each platform's limit. With another tool, do the staggering and the rewording by hand; it is tedious, which is precisely why it usually gets skipped.

Step 5: watch the Calendar, not the apps

Once posts are scheduled you should be able to see, in one place, what is queued, what went live (with a link to the post) and what failed with a readable reason. In PostingClips that place is the Calendar — by month, by week or as a list — where you can also post now, move a post to another day, cancel it or retry it. Failures happen — a token expires, a Page loses a permission, a clip is a second too short for a platform — and the fix is nearly always to reconnect the account or retry the post, not to re-do the content.

Two limits worth respecting: keep any single account under about ten scheduled posts per day (Instagram's hard limit is far higher, but the spam zone starts long before it), and never schedule the same clip twice on the same account. PostingClips refuses both.
