Where Mayday fits alongside your ledger

Xero and QuickBooks Online record each cost where it was paid. Mayday applies the allocation rules you set and posts the resulting entries back, so each entity, department and cost centre carries its share.

Post the resulting journals, invoices or bills to Xero or QuickBooks Online in a click

Our AI-powered engine transforms how you handle month-end operations, helping you save hours and eliminate costly errors.

First, AIR applies recognised accounting principles to make intelligent decisions like "should these transactions be matched?" or "should this have deferred revenue treatment?"

Then, AIR applies your individual business context, learning what's typically done in your specific accounting files to suggest actions tailored to your workflows.

How does Mayday automate cost allocation?

Intercompany cost allocation

Distribute shared expenses across the entities that benefit from them, such as a £10,000 software subscription split between five subsidiaries.

Recharge at cost, or at cost plus a mark-up.

Post matching invoices and bills, or journals, in each entity.

Keep the intercompany balances that result in agreement with Balancer.

See how Recharger works

Recharger listing utilities transactions in one entity to recharge to another group entity, with a button to post the entries.
Recharger showing transactions allocated by rule, including advertising, travel and accountancy splits and a telephone percentage split.

Interdepartmental overhead allocation

Spread indirect costs such as rent, insurance and central administration across departments, locations or tracking categories.

Leave a share behind where you need to, for example keeping 10% for management overheads.

Works within a single entity, so you don't need a group structure to use it.

See each department's full cost base without posting reclass journals by hand.

How intra-entity allocations work

Recurring allocations without the spreadsheet

Set allocation rules once, using account code, contact, reference or line description to pick up the right transactions.

Save apportionments based on headcount, revenue or floor space and reuse them across rules.

Update an apportionment in one place when headcount changes.

Review each month's calculation and override individual transactions before anything posts.

Creating a new expense recharge rule in Mayday, filtering transactions by account code, contact, reference or line description.
