Should use method (1) .
In fact, "debit note" should be issued (instead of "Invoice") for the Material paid on behalf.

Holding Co.

(neglect the accounting entry for the payment to vendor)

* No accounting entry should be booked in "SALE" account
And No more sale to be made.

** The overstated of Sale : usually issue INVOICE to your sub. co. by selling the goods / service provided by making a unreasonable margin.
So that Profit would be transferred.
In audited report, the Interco Transaction should be disclosured.
In result, auditor will ask you to provide the detail (e.g. amount & classification) for the interco transcations when processing their audit work.

In my opinion, if the auditor finally checks out such accounting treatment & will then needs to do the Audit Adjustment (AA). Some co does not want to make any AA , auditor also question why such entires are done), the companies would prefer to a proper a/c entries instead of AA.

你應該照開發票給附屬公司,
即入賬如下:

主公司
借 往來賬 (Current account)
貸 銷售 (Sales)

附屬公司
借 購貨 (Purchase)
貸 往來賬 (Current account)

由於你公司是集團式, 所以要做consolidation account.
在consol account內便要做一條interco elimation entry 如下:

借 銷售
借 往來賬 (附屬公司)
貸 　 購貨
貸 往來賬 (主公司)

It is a payment made by holding company (H) on behalf of the subsidiary (S). The procedure should be H company issue a debit note to S for the amount paid together with the supporting bill. On receipt of this debit note, S could either settle it by bank just like an ordinary transaction by
(1)
Dr. Job expenses
Cr. Bank

or via a transfer voucher by
(2)
Dr. Job expenses
Cr. Current Account with the Holding Company.
------------------------------------------------------------------------------------------------------------------------
The entries in H will be
(1)
On payment on behalf of S

Dr. Current Account with the Subsidiary
Cr. Bank

On receipt of cheque from S

Dr. Bank
Cr. Current Amount with the Subsidiary
(2)
Or record the transaction via a transfer voucher

Dr. Current Amount with the Subsidiary
Cr. Bank
If you look at the above entries, this is simply a payment on behalf. No sales will be affected.

主公司（工程公司）幫了附屬公司（都是工程公司）代付了一批ＣＯＧＳ（工程物料），

You can :
Debit: Related Company (Balance Sheet Item)
Cr Bank

Therefore it doesn't matter with overstated the sales(income statement).

When related company paid back to you.

You can:

DR Bank
CR Related Company

It is only the contra account for the accounting entries.

首先，應該要debit返主公司既Cash, Credit Acc. Receivable, 因為附屬公司要俾返果D錢主公司
跟著附屬公司要Debit Acc. Payable, Credit Cash, 咁樣附屬公司就會俾返未俾既錢主公司, 而又唔會出現double counting
