Billing & Credits

WillItTrack uses a credits-based billing model with no subscriptions. Every account gets free checks each month, and additional checks are paid via pre-purchased credit packs.

Free Tier

Every month, free checks reset automatically. No credit card required.

Check Type	Authenticated	Anonymous
Link Check	50 / month	5 / month
CMP Check	10 / month	Not available
Basket Check	3 / month	Not available
Checkout Check	1 / month	Not available

Check Costs

Once you exceed the free tier, credits are deducted per check:

Check Type	Cost	Estimated Duration
Link Check	1p (0.01 GBP)	~30 seconds
CMP Check	3p (0.03 GBP)	~90 seconds
Basket Check	5p (0.05 GBP)	~5 minutes

Credits are deducted atomically after a successful scan. If the scan fails, no credits are charged.

Credit Packs

Purchase credits via Stripe Checkout. Credits never expire.

Pack	Price	Equivalent Checks
Starter	5 GBP	500 link / 166 CMP / 100 basket
Standard	25 GBP	2,500 link / 833 CMP / 500 basket
Pro	100 GBP	10,000 link / 3,333 CMP / 2,000 basket

How Billing Works

1When you make a check request, the API first checks if you have free checks remaining this month.
2If the free tier is exhausted, it checks your credit balance for sufficient funds.
3If both are exhausted, the request is rejected with a 402 /insufficient_credits error.
4Credits are deducted atomically after the scan completes. Failed scans are not charged.
