Accounts Payable Management: How to Pay Suppliers Smarter

Accounts Payable: More Than Just Paying Bills

We had a client — a wholesale trader in Pune — who was convinced his cash flow problem was a revenue problem. Sales were fine. Collections were slow but manageable. What he couldn't figure out was why the bank balance always looked worse than it should.

Turned out he was paying invoices on average 12 days before they were due. On ₹40 lakh of monthly purchases, he was essentially giving his suppliers an interest-free loan of about ₹16 lakh at any given time. That's money his business needed.

Accounts payable is where most businesses leave significant cash on the table. And it's not because they're ignorant — it's because the function gets treated as clerical work rather than financial strategy.

Businesses that manage payables well:

• Use every day of available credit terms — cash stays in the business longer
• Capture early payment discounts only when the maths actually work
• Build supplier trust through consistent, reliable payment (not necessarily fast payment)
• Catch duplicate payments and pricing errors before money leaves the account

Businesses that manage it poorly:

• Pay too early out of habit or anxiety
• Pay too late when things get chaotic, creating penalties and damaged relationships
• Pay incorrectly — duplicates, wrong amounts, invoices for things not yet received
• Have no visibility into what's due in the next 30 days

The Accounts Payable Cycle

If you're going to improve something, you need to understand each step where things can go wrong.

1. Purchase Order creation: The PO specifies what's being ordered, at what price, and with what payment terms. This is the baseline everything else gets matched against.

2. Goods or services receipt: This is the moment that actually creates the liability — not when you raised the PO. We see businesses getting this wrong constantly. You don't owe the supplier anything until you've received what you ordered.

3. Invoice receipt: The supplier sends the invoice. The clock on payment terms starts here (or at goods receipt — check your terms carefully, they vary).

4. Three-way match: Matching PO, goods receipt, and invoice. Did we order this? Did we receive it? Does the invoice price match what was agreed? All three must align.

5. Approval: Invoices above a defined threshold need sign-off from someone authorised to approve that level of spend.

6. Payment scheduling: Approved invoice gets a payment date — the last appropriate day within the credit terms, not the first available opportunity.

7. Payment execution: Money goes out via the appropriate method.

8. Reconciliation: Payment matched in the accounting system, supplier account updated.

Each of these is a control point. Skip steps — especially the three-way match — and you're inviting costly mistakes.

The Three-Way Match: Your Fraud and Error Prevention System

This is the most important control in the whole AP process, and it's the one most businesses skip when they're busy.

The three-way match confirms:

• You ordered the items (purchase order exists)
• You received the items (goods receipt note exists)
• The invoice correctly reflects what was ordered and received

Without it, the errors that slip through are expensive:

• Invoices for goods not yet received — you're paying before delivery
• Quantities on the invoice differ from what arrived
• Price on the invoice differs from the agreed PO price (supplier error or deliberate overcharge)
• Duplicate invoices — same invoice submitted twice, either accidentally or not

We've seen all of these. The duplicate payment one is particularly painful because recovering it from a supplier after 90 days is genuinely difficult. Some just apply it as a credit, which means you never see the cash again.

For businesses with high invoice volumes, three-way matching can be automated through accounting or ERP software. For lower volumes, even a simple spreadsheet cross-check process gives you the same protection.

Using Credit Terms Strategically

Supplier payment terms are free short-term financing. A 30-day payment term on ₹10 lakh of monthly purchasing means you have ₹10 lakh of supplier credit working in your business at any given time — money you haven't had to borrow.

Use every day of your terms. Paying a 30-day invoice on day 15 means you've given your supplier 15 days of free financing at your expense. There's no relationship benefit to paying early unless a discount is on offer. Pay on the last day within terms.

Negotiate better terms as the relationship matures. If you've been paying reliably for 12 months, ask for 45 days instead of 30. On ₹50 lakh of annual purchasing, moving from 30 to 45 days frees approximately ₹2 lakh of working capital permanently. It costs you nothing except the conversation.

Understand the early payment discount maths. Some suppliers offer "2/10 net 30" — 2% discount for payment within 10 days versus full payment in 30 days. The annualised cost of not taking that discount is around 36%. If your overdraft rate is less than 36% (it almost certainly is), take the discount. If you're cash-constrained, skip it and use the full 30 days. Either way, make the decision deliberately rather than defaulting to one approach.

The Payment Run Discipline

Ad-hoc payment — paying invoices as they arrive or when someone remembers — is where errors accumulate. A structured payment run on a fixed schedule is better in every way.

Weekly or twice-weekly payment runs:

Pull all approved invoices due within the next payment cycle

Confirm the available bank balance

Process all payments in a single batch

Reconcile immediately

This approach ensures nothing gets missed, consolidates the admin effort, and creates a clear audit trail of what was paid, when, and why. Your accountant will thank you. Your auditor definitely will.

Preventing Duplicate Payments

Duplicate payments are more common than businesses realise and they directly remove cash. Common causes we see:

• Same invoice emailed twice and processed twice — supplier resends because they didn't get a confirmation
• An invoice and a statement both processed as invoices
• Invoice paid, then re-entered after a system migration or software change
• Different invoice reference numbers for the same charge from the same supplier

Prevention:

• Assign a unique internal reference to every invoice on receipt and check for duplicates before approving
• Use accounting software with duplicate detection — most modern systems flag potential matches
• Reconcile supplier statements monthly — the supplier's statement shows if a payment was applied twice

When you catch a duplicate after payment, contact the supplier immediately. Most will apply it to the next invoice or refund it. The longer it sits, the harder recovery gets.

---

Supplier Statement Reconciliation

Once a month, compare what your accounting system shows as outstanding against what the supplier claims is outstanding. This catches:

• Invoices the supplier says they sent but you have no record of
• Payments you recorded but the supplier hasn't applied
• Disputes about credit notes or returns that quietly disappeared

For high-volume or high-value suppliers, this is essential. A monthly reconciliation takes 15 minutes per supplier and prevents disputes that would otherwise surface months later when they're much messier to resolve.

The Ageing Report: Your Forward Visibility

The AP ageing report shows every outstanding invoice by how far its payment date is in the future — or past:

• Not yet due: within payment terms
• 0–30 days overdue
• 31–60 days overdue
• 60+ days overdue

We recommend reviewing this weekly. Use it to:

• Spot upcoming large payments that will affect your cash position
• Identify anything overdue that could damage a supplier relationship
• Flag invoices stuck in the approval process that shouldn't be

A clean ageing report means everything sits in "not yet due." Consistently overdue balances are either a cash flow problem or a process problem — both need attention before they compound.

The Payables-Payroll Priority

When cash is tight, the order matters. This is not negotiable:

Payroll always first. Failing to pay staff on time is both legally problematic and devastating to team trust. It's not recoverable easily.

Tax and statutory obligations second. Late tax payment creates penalties and interest that compound. In India, GST interest alone runs at 18% per annum.

Critical operational suppliers third. The suppliers whose goods or services you genuinely cannot function without.

All other suppliers in order of terms. If you're going to be late, communicate proactively. Most suppliers would rather know in advance than get silence and then a partial payment.

Never prioritise a supplier payment over payroll. Never. Not even a critical supplier.

Building an AP Process That Protects the Business

The goal isn't to make it harder to pay suppliers. The goal is to ensure every payment is for something genuinely received, at the right price, at the right time — and that nothing slips through undetected.

When AP is working properly:

• Errors and duplicates get caught before money leaves
• Credit terms are maximised rather than surrendered early
• Supplier relationships are maintained through reliability, not speed
• Fraud risk is reduced through authorisation controls and matching

It's genuinely one of the highest-leverage, lowest-glamour improvements available to a growing business. Nobody gets excited about accounts payable until they find a ₹3 lakh duplicate payment that's 180 days old and essentially unrecoverable. Then they get excited.
