Step 4 · Petty expenses (the ones with no invoice) ​

In one sentence ​

Stationery, a laptop the boss paid for himself, a renovation balance with no proper invoice — all of it goes on this one page. One screen, and the system does the bookkeeping for you.


1. When to use this page ​

SituationThis page?
The boss paid for a laptop out of his own pocket✅ Yes
Stationery, you only have a till receipt✅ Yes
Renovation balance, no proper invoice✅ Yes
Staff paid for a taxi and claims it back✅ Yes
A supplier issued a proper invoice (letterhead, UEN)❌ No — use Step 5
Salaries❌ No — use Step 7

Rule of thumb: proper invoice → Bills. Till receipt or nothing → this page.


2. The page ​

4. 🔴 "Paid by" — this one decides the bookkeeping ​

The most important field on the page. It tells the system where the money came from:

You pickMeaningSystem records
Company bankPaid from the company DBS accountBank balance goes down
Company cashTaken from the office cash boxCash goes down
Director advanceThe boss paid personallyThe company now owes the boss (2600 Due to director)
Staff advanceStaff paid, claiming it backThe company owes the staff member (2610)

Why "director advance" isn't a cash payment

When the boss pays personally, the company's cash and bank are untouched — but the company now owes him.

That debt only becomes a real cash outflow when he takes the money back. Get this wrong and your cash balance stops matching the bank.

This trips up most beginners, and it's the normal case during the Academy's setup period — the company account may not even have existed yet, so almost everything was advanced by the boss.

Picking Company bank reveals an extra Bank account dropdown — choose DBS Current Account.


5. GST code: pick NG ​

The Academy is not GST-registered, so:

  • GST charged by suppliers cannot be reclaimed — it's simply part of the cost
  • Always pick NG (No GST — not registered, input tax absorbed into cost)
  • Enter the total you actually paid, GST included

Don't pick TX

TX means "reclaimable input tax". Pick it and the system books 9% input GST that the Academy cannot actually claim — the books go wrong. Use NG.

If the Academy registers for GST later, this rule changes and this manual will be updated.


6. After you press "Post expense" ​

The system books it immediately and it appears in the list below.

Example: the boss advances $1,899 for a laptop

What the system books
Dr 1410 Computers & IT equipment$1,899.00
Cr 2600 Due to director$1,899.00

In plain words: the company gained a $1,899 laptop and now owes the boss $1,899.


7. If you get it wrong ​

Posted entries cannot be deleted or edited

This is a hard rule of accounting systems, not the software being awkward — books that can be quietly edited are books an auditor won't accept.

Press Reverse on that row. The system creates an equal and opposite entry that cancels it out. Then enter the correct one.

You end up with three records (wrong, reversal, right). That is normal and correct — the audit trail is supposed to show what changed.

So: check the amount and the company name before you press Post.


8. Tag setup-period costs ​

Costs from before the Academy opened are worth being able to total separately (for tax and for management).

If you see a Phase option, pick Pre-opening for setup-period costs and Operating afterwards.

Not sure which side something falls on: use the first day of classes as the cut-off.
