How to reconcile TikTok Ads against your point-of-sale system
This is the check we run first on every account, written out so you can run it without us. It takes about thirty minutes and needs two numbers: what TikTok says it produced, and what your point-of-sale system actually shows. The gap between them is the only honest measure of whether your tracking works — and if it comes back small, you do not need us.

TikTok vs in-store sales: an offer code beats any upload
TikTok's ttclid never reaches the till, so per-record matching depends on hashed email or phone sent as offline events through the Events API, if your account supports them. For most stores a TikTok-only offer code is the cleaner join. Compare a closed month; a reported in-store figure much larger than code redemptions deserves suspicion.
TikTok audiences rarely hand over an email at a counter, which makes hashed matching thin even where offline events are available. Check TikTok's current documentation for whether offline or in-store events are accepted on your account and which identifiers they take. Where contact details are scarce, a code shown only in TikTok creative and keyed into the POS as a discount gives you an exact row-level key that needs no upload.
TikTok's attribution windows differ from Meta's and include view-through by default on some objectives, so check the setting before comparing anything. Its reporting dates results to the ad interaction, while your POS dates by business day. Pull results by campaign with the attribution window shown, then compare against POS transactions carrying the TikTok code for the same weeks, not against total in-store revenue.
If TikTok drives footfall at all, expect code redemptions to sit well below any modeled in-store estimate; people come in without mentioning the ad. A TikTok number that grows with seasonal footfall while code use stays flat points to view-through credit, not real visits. The most common disagreement is simpler: the code gets shared on coupon sites, so redemptions overstate TikTok and the platform understates it.
TikTok × POS System · what breaks
Why TikTok and your point-of-sale system disagree
- 01
Counter sales flowing into online conversions
Where the POS and the online store share an order table, the default integration sends everything. Reported return then climbs with footfall.
- 02
Store visits treated as attributable
Platform-reported store visits are modelled estimates, not counted events. Read them as directional and never sum them with online conversions.
- 03
Tips and taxes inside the conversion value
On food and service businesses tips are substantial and are not your revenue.
- 04
Offer codes never used
Without a code or a distinct landing path, there is no mechanism at all to connect in-store revenue to advertising.

What each side is actually counting — TikTok × POS System
- 1
What TikTok counts
A standard event name, an event timestamp, a shared event ID, hashed and normalized user identifiers, and ttclid where available. Confirm the current required fields in TikTok's documentation before building.
- 2
How TikTok attributes it
TikTok's click identifier, appended to the landing URL. Capture it on landing and persist it exactly as you would gclid or fbclid — it's the strongest matching signal available and the most commonly missing one, because TikTok is often added to a stack that was built around Google and Meta.
- 3
The window it uses
Verify the current attribution and import windows in TikTok's documentation. They differ from Google's and Meta's, and quoting a number here that goes stale would be worse than sending you to the source.
- 4
What your point-of-sale system counts
Transactions taken in person, which advertising cannot attribute to a click, found in Square, Lightspeed, Toast, Clover or whatever runs the till.
- 5
The filter that makes them comparable
In-person channel only, separated from any online orders in the same system.

Reading the gap — TikTok × POS System
| What you see | What it usually means |
|---|---|
| 15%+ platform higher | Usually the wrong event entirely — the channel filter is missing, so counter sales are being counted as advertising conversions. |
| 20%+ platform lower | Usually structural — almost always correct rather than a fault. in-store revenue mostly cannot be attributed, and a small reported figure is the honest one. |

TikTok is usually the third platform added to a stack, and it typically inherits whatever assumptions were made for Google and Meta. The most common result is that ttclid is never captured at all, because the capture code was written naming gclid and fbclid and nobody revisited it.

TikTok × POS System · when not to buy
When the answer is that you do not need us — TikTok × POS System
- If almost all of your in-store transactions come from a channel with no click behind it, no tracking work will reach them — and knowing that is worth more than a build.
- If TikTok is a small share of your spend, the effort is better spent making Google and Meta correct first — the same infrastructure then extends to TikTok as one additional tag rather than a separate project.

FAQ
TikTok × POS System questions, answered
It is a floor rather than the full effect, because many customers who saw the ad never mention it. Watch for leakage to coupon sites, which inflates the floor.
Not from your POS. Anything TikTok reports about physical visits without your data is modeled, so treat it as directional and keep it out of revenue totals.
Because you should know the size of the problem before anyone quotes you for it. If the gap is small, you have saved yourself a purchase. If it is large, you now know what you are buying rather than taking our word for it.
No. Both numbers come from systems you already own and neither leaves them. There is no tool to sign up for and nothing to upload.
Then compare totals for a closed period and treat the result as directional rather than exact. Tiktok's own event diagnostics, plus a reconciliation against your records is still the right place to read the platform's side.
Under five percent is working. Five to fifteen usually means reversals are missing. Above twenty is normally the wrong event being counted, not a broken tag — which is why debugging tags first wastes so much time.
Then fix the filter before drawing any conclusion. In-person channel only, separated from any online orders in the same system. A mismatch in scope produces a gap that looks like a tracking fault and is not one.
