I have a number of transactions that I want to re-categorise . Can I set up a Rule and catch them all in one go .

Yes, you can set up a rule to categorise your bank transactions, opus1956-me-com.

Once transactions are downloaded from your bank, you'll have to categorise them so they go into the right accounts. Bank rules speed up the review process. To create one, follow the steps below:

1. Go to Bookkeeping and select Rules (Take me there).
2. Select New rule.
3. Enter a name in the What do you want to call this rule? field.
4. From the Apply this to transactions that are ▼ dropdown, select Money in or Money out.
5. From the In ▼ the dropdown, select the bank account.
6. Set the rule conditions. You can set a single rule with up to 5 conditions. Set and include the following, then select + Add a condition.
7. In the Conditions fields, specify whether the rule applies to Description, Bank text, or Amount. Then select Contains, Doesn't contain, or Is exactly to decide how QuickBooks applies the rules.
8. Select the Transaction type, Category, and the Payee to apply.
9. Select Save.
