Credits and billing

The invoice does not add up

Where to look to explain a month that came out unusual.

Open it in the platformUpdated on 13/08/2026

A month spikes and nobody remembers doing anything different. There is nearly always a concrete explanation, and it is in the breakdown: spend is not spread evenly, it concentrates in two or three things.

The four causes, by frequency

CauseHow to spot itWhat to do
A large batch someone launchedA spike on a single dayCheck who and why; it is usually legitimate
SMS left on by default in a processSteady, spread-out spendRestrict SMS to people who do not read email
Reading enabled on a type that yields nothingRises with upload volumeDisable reading for that type
Resends of a badly filtered batchDuplicates on the same dayFilter for who did not receive before relaunching

How to review it in ten minutes

  1. 1

    Open the month's breakdown and sort by item, not by date.

  2. 2

    Check whether one process accounts for more than half.

  3. 3

    Compare with last month: what changed is what needs explaining.

Worth knowing

Before cutting, check whether the spend is returning something. An expensive month because the annual review of 300 suppliers went out is not a problem: it is the annual review, and last year it was done by hand.

Watch out

Be careful cutting SMS wholesale to save money. If those were the ones reaching people who do not read email, next month you will spend less and receive less, which costs more.

Important

If the spike is explained by none of this, check it against the activity log before assuming a billing error. Consumption nobody recognises deserves a look at who launched it.

Can I see spend per person?

It is shown per process and per team, which is usually what explains it.

Can the breakdown be exported?

Yes, with its dates.

Are reminders charged separately?

No. Chasing an already-paid send is not charged again.
