A single Microsoft tenant.
Several organisations inside it,
each with its own budget.
That is what multi-budget means.
Divisions, subsidiaries, agencies,
member firms. All sharing one tenant,
each answering for its own spend.
Together they fund a pool
of prepaid Copilot credits,
at a lower rate than paying as they go.
That pool is shared across the whole tenant.
And it is drawn down first come, first served.
So whoever consumes earliest
receives the discounted rate.
The others move on to pay as you go.
Which means a division can pay the higher
rate, for credits it funded itself.
You might expect spending policies
to solve this. In the admin centre,
you assign them to security groups,
and set a ceiling per person.
They do govern access and spend.
But they cannot reserve credits.
No policy holds part of the pool
for one organisation.
Which is what the Multi-Budget
Chargeback Report is for.
Open it from the Analytics Hub.
Everything runs in your browser.
No file is uploaded,
and no data leaves the machine.
You need two exports you already have.
Your user list from Entra,
and your Copilot consumption report.
Load them, and the report
opens on the settlement.
It walks the maths through,
step by step, on your own figures.
Microsoft bills the tenant as a whole.
Each organisation states the share
of the pool it funded. Its entitlement.
Every bill is rebuilt from that entitlement.
Credits within it are charged
at the prepaid rate.
Anything above it, at pay as you go.
Consumption order is no longer
part of the calculation.
So it no longer decides who benefits.
So where do those entitlements come from?
Start by downloading the template.
It arrives with every organisation already
listed, and the credits each one used.
No name is typed by hand.
Open it in Excel, and fill
in the share each organisation funded.
Then load that same file straight back in.
The report confirms what matched,
and flags anything it does not recognise.
So a mistyped name can
never quietly bill at zero.
And if you have not yet agreed who funded
what, the report can propose a split for you.
By headcount, by usage, or evenly.
One detail deserves attention.
Billing each organisation against
its own entitlement collects slightly
more than Microsoft charged.
Because some organisations
funded credits they never used.
Someone else consumed those
credits at the prepaid rate,
and is billed pay as you go for them.
So you choose. Redistribute
it to those that went over,
or rebate it to those that underspent.
Either one reconciles exactly.
Or simply hold it centrally.
Then export. Post to GL gives one row
per organisation. The period,
the amount, and how it was calculated.
It imports straight into Apptio,
or any finance system,
with nothing to strip out.
And it adds up to the invoice, to the penny.
The workbook is for review and sign off.
The line items export is your audit trail.
One tenant. Many budgets.
Settled fairly, in minutes.
