Managing Supplier Bills and Payables in a Welfare Association
How to record supplier bills when they arrive, pay them in an orderly way, and keep a payables list that matches your books, with a simple monthly routine.

The security agency says last month's invoice is unpaid. The treasurer is sure it was paid. The cheque book stub is blank, the invoice has no "paid" mark, and nobody can remember. Disputes like this are almost always a sign that supplier payables are being handled from memory rather than from the books. A simple discipline fixes it.
What supplier payables are
Supplier payables are the amounts the association owes to the people and companies that provide goods or services: security agencies, cleaning contractors, lift and generator service firms, electricians, plumbers, stationery shops and so on.
Many associations only record an expense on the day they pay. That works for small cash purchases, but for regular suppliers it hides an important fact: between receiving a bill and paying it, the association owes money. If that is not in the books, the committee cannot see what is outstanding.
Bill first, payment second
The cleaner approach is to record two separate events:
- When the bill arrives: record a supplier bill voucher. Debit the expense head (say, "Security services"), credit the supplier's payable account.
- When you pay: record a payment voucher. Debit the supplier's payable account, credit cash or bank.
After both entries, the supplier's balance is zero and the expense is recorded in the month the service was provided, not the month you happened to pay.
| Step | Debit | Credit | Effect |
|---|---|---|---|
| Bill received ৳45,000 | Security services | Supplier payable | Expense recorded, amount owed |
| Paid ৳45,000 by cheque | Supplier payable | Bank | Amount owed cleared |
For a ৳300 cash purchase of light bulbs, a direct payment voucher is fine. Use the bill-then-pay method for any supplier you deal with regularly or any bill you do not pay on the spot.
A simple bill-handling routine
Say a 200-flat association has eight regular suppliers. A routine that keeps things under control:
- One inbox for bills. All bills go to the office or treasurer, never to whoever happens to be around. Stamp or write the date received.
- Check before recording. Confirm the work was done or the goods received. For a repair, the person who supervised it signs the bill.
- Record within a few days. Enter the supplier bill voucher with the bill number and period in the narration, for example "Security services, September, bill no. 1182".
- Approval. A second committee member reviews the bill voucher before it posts.
- Pay on a set schedule. For example, regular suppliers are paid in the first ten days of the following month, after the bill is approved.
- Mark the bill as paid. Write the payment voucher number and date on the bill itself, and file them together.
Tip: Ask regular suppliers to put a bill number and service period on every invoice. Bills without numbers are the main source of double payments.
Keeping a supplier ledger
Each supplier should have their own account or sub-ledger so you can see, at any time, what has been billed, what has been paid and what remains. When a supplier says they are owed money, you open their ledger and walk through it line by line together. Disputes become a ten-minute conversation rather than a week of arguments.
At month end, compare:
- The total of all supplier balances in the books
- The pile of unpaid bills in your "to pay" file
They should match. If they do not, a bill was either recorded but not filed, or filed but not recorded.
Partial payments and advances to suppliers
- Partial payment: record the payment against the supplier's payable as usual. The ledger will show the remaining balance. Note on the bill how much was paid and when.
- Advance before the work: if a contractor asks for 30% upfront, record it as an advance to that supplier (an asset), then set it off against the bill when it arrives.
- Disputed bill: do not record a bill you have not accepted. Keep it in a separate "under review" file and note the reason.
Signs your payables need attention
- Suppliers chasing payments you thought were made
- Expenses showing up in the wrong month, making monthly comparisons meaningless
- Year-end accounts that need a long list of "bills received later" adjustments
- Cheques written without a bill attached
- The same supplier appearing under several slightly different names
If tax deduction at source or VAT applies to any of your supplier payments, the rules are specific and change from time to time. Ask your auditor or a tax adviser rather than guessing.

Supplier payables in Society Keeper
Society Keeper has a dedicated supplier bill voucher alongside receipt, payment, journal and contra vouchers, so bills can be recorded when they arrive and paid later against the same supplier. With maker-checker approval, one person enters the bill and another approves it. The supplier payables report shows what is owed to each supplier at any time, and the monthly expense analysis shows spending by head. More practical accounting guides are on our blog.
