I’m afraid to say that wouldn’t be possible as the accounts of each are independent.
I think something like the following would be OK, providing you have sufficient evidence to show that the income is for the one business rather than the other.
- On the ST account, reduce the incoming amount to reflect only what that business took (e.g. out of the £6,000, if it only took £2,000, then only show it as £2,000 coming in).
- Create the balancing entry on the other account (in this example, £4,000 to make the £6,000 in total), and treat them as separate.
The other way to do it (although I would seek advice from someone more qualified than me on doing this before proceeding), would be to perhaps have the one business invoice the other. It’s certainly possible to link the accounts that way. There’s more on this feature at the link below:
