Measure TikTok Ads against real profit
MerchantFlow tracks TikTok campaign spend and performance and nets it into your profit view, so you can judge TikTok on profitability, not just clicks.
TikTok drives volume, and volume is easy to mistake for performance. Cheap clicks and a high conversion count can hide the fact that the orders behind them were discounted, low-margin, or heavily returned.
MerchantFlow syncs daily TikTok campaign spend and performance and sets it against the orders it produced, net of product cost, payment fees, shipping, and refunds. TikTok then sits in the same profit view as every other channel, measured the same way.
Spend, impressions, clicks, and conversions come in daily at the campaign level and are backfilled on connection, so earlier periods stay comparable rather than starting from the day you signed up.

How teams use it
TikTok is often judged too early or on the wrong number. A campaign is switched off because in-platform ROAS looked weak, or scaled because it looked strong, when neither figure accounted for what the orders were worth.
- Compare TikTok on contribution margin against your other channels before deciding to scale or cut.
- Check the refund rate on TikTok-driven orders, since impulse-led purchases can return at a different rate.
- Look at which products TikTok actually sells, then check each one against its own break-even ROAS.
- Use blended MER as the guard rail when TikTok and Meta both claim the same conversions.
Common questions
Frequently asked questions
Is the connection secure?
Yes. MerchantFlow uses TikTok's official authorization flow and reads reporting data only.
Can I see profit, not just ROAS?
Yes. TikTok spend is netted into profit using your real COGS and fees.
Is it read-only?
Yes. MerchantFlow cannot change your TikTok campaigns or budgets.
How often does spend update?
Spend syncs automatically on a recurring schedule through the day, with manual sync available. Recent days are re-checked on later syncs, so figures settle as TikTok finalises reporting.
Can I connect more than one advertiser account?
Yes. Multiple TikTok advertiser accounts can be connected under one login and reported on together or separately.
Why does MerchantFlow show a lower return than TikTok does?
TikTok reports revenue it attributes to an ad. MerchantFlow reports what was left after product cost, payment fees, shipping, and refunds. The gap between the two is your actual margin.
Is historical spend included when I connect?
Yes. Past spend is backfilled on connection so earlier periods remain comparable rather than starting from zero on signup day.
Does this cover TikTok Shop orders?
This integration covers TikTok Ads spend and performance. Orders are read from your connected commerce platform, so any order that reaches Shopify or WooCommerce is included in your profit view.
