Rules in Mayday Recharger describe the logic behind how transactions are recharged between your entities. It's a simple process to create the rules, but it’s important to do this with care. Mistakes in your rules can lead to mistakes and oversights in your recharge calculations, and these could cost you more time further down the line.

There are four types of rule in Recharger:

We'll look at these in more detail below.

Recharger creates three 'Don't recharge' rules by default for each entity in the recharge group. These apply to all transactions in that entity (expense, revenue, and balance sheet) and won't recharge them to any other entity in the group. You can override these rules, or remove them completely, by creating rules which supersede them.

You can start creating an expense rule using the 'Add new expense rule' button:

This takes you to the New Expense Recharge Rule page:

There are three types of expense rule you can create:

Once you've chosen the type of rule you're creating, you'll need to set up the transaction matchers. This is described in the Transaction Matching section below.

You can create a new revenue rule with the "Add new revenue rule" button:

This will take you to the New Revenue Recharge Rule page:

There are two types of rule you can create here:

Section 4 lets you define which other entities should receive revenue from revenue rules:

You can add whichever entities are required using the '+ Add another entity' button. The figure you enter in the '% of Revenue' column is what percentage of the transaction's value will be recharged. Finally, the last column is the account code the revenue will be assigned to in that entity.

Once you've chosen the type of rule you're creating, you'll need to set up the transaction matchers. This is described in the Transaction Matching section below.

You can create a new balance sheet rule with the "Add new balance sheet rule" button:

This will take you to the New Balance Sheet Rule page:

There are two types of rule you can create here:

Once you've chosen the type of rule you're creating, you'll need to set up the transaction matchers. This is described in the Transaction Matching section below.

You can create a new Mayday rule by clicking "Mayday Rules" then the "+ Add new" button:

This will take you to the "New Mayday Rule" Page:

Then you follow the steps to setting up a Mayday rule:

Once you've chosen the type of rule you're creating, you'll need to set up the transaction matchers. This is described in the Transaction Matching section below.

For all rule types, you'll define parameters to configure exactly which transactions in that entity the rule will be applied to.

The first option is to apply the rule to all transactions under that entity. Choosing this will mean the rule becomes the default rule for that entity, and it will be applied to all transactions which do not match other rules you've configured. You can only have one rule with this option set - if you wish to change which rule that is, you'll need to edit that rule's configuration first.

The second option is to define matchers to tell Recharger how to identify the right transactions for this rule. You can define as many of these as you'd like, and configure whether to match all or any of them:

You can create matchers based on the following transaction properties:

In the event that a transaction matches more than one rule, Recharger will pick one of the rules based on a set precedence order, shown at the bottom of the page.

Once the transaction matchers are set up, you can define how the matched transactions will be apportioned between other entities in the recharge group. There are two ways of doing this.

You can use the Apportionments page to define commonly-used apportionments. This is handy if you'd like to use the same methodology to apportion several different recharge rules. Doing this means you'll only need to update them in one place if they change in the future. See 'Apportionments' for more info.

When you choose a pre-defined apportionment, the list of entities and the numbers will be pre-filled for you. You only need to set the account codes: this is where the cost from this recharge rule will be posted in that particular entity's accounting system.

Choosing 'Custom' gives you much more flexibility in defining the apportionments. You can choose whichever other entities you'd like from your recharge group, and then adjust the apportionment percentages using the apportionment and 'total apportionment units' boxes. The 'total apportionment units' is a whole number from which you create fractions using the 'apportionment units' above.

You will then need to set the account codes: this is where the cost from this recharge rule will be posted in that particular entity's accounting system.

With Recharger, you can split costs and revenues between account codes or tracking categories both within and between entities. If you want to create inter-departmental recharges, follow the steps in 'How do I create Intra-entity Recharges?'

In the event that a transaction matches more than one rule, Recharger will pick one of the rules based on the following precedence order:
