Billing, receipts and your details

Topping up

Pick a pack and pay on the payment provider’s own page. We never see your card — the same rule we enforce on every app this builds.

A payment is not the same thing as a credit: the attempt is recorded when you start, and the balance moves only when the provider’s own server confirms the payment and the amount matches what we asked for. An abandoned checkout leaves a trace and no balance, and refreshing the return page is not free money.

Your billing details

Add them on their own page rather than in the middle of a payment — nobody should be hunting for a GSTIN with a payment window open. State is required, because it decides how the tax is split, and if you give a GSTIN it is checked both for shape and for agreeing with the state you picked.

A well-formed GSTIN from the wrong state is invisible on the form and turns up months later as a rejected input-credit claim nobody can trace back.

Receipts

Built once at payment and stored whole. If you move office next year, last year’s receipt still says what it said — otherwise it was never really issued.

Spark prices include tax; domain prices add it. The receipt says which convention it used, and the parts always add back to exactly what you were charged.

Running out

The builder stops and holds the sentence you were about to send. Topping up does not run it; you press send. Money arriving is not permission to spend it.
