Your invoice gives them a reason
Missing PO, wrong rate, no delivery proof, wrong GSTIN.
Answer these questions before you read on
Commit to an answer before you open each one. Together they show where the problem is.
1How many days does each of your top ten customers actually take to pay?
Not the agreed terms: the real days. That's the number that runs your bank account.
2When did someone last call a customer the day an invoice fell due?
Most follow-up starts weeks after the due date. By then, you're at the back of the queue.
3How many invoices came back last quarter for a wrong PO number, rate or document?
Every returned invoice resets the clock. Customers rarely tell you; they just wait.
4What does 30 extra days of credit cost you on a 10% margin?
At a typical CC rate, close to a tenth of your margin, before any bad debt.
5Is there a customer you keep supplying even though they're past 120 days?
That's not a customer; it's a loan you didn't approve.
Late payment is mostly a process problem, not a customer problem.
The four reasons customers pay late
Invoice
Follow-up
Nobody asks in time
Follow-up starts after the due date, or not at all.
Terms
The terms were too long
Credit agreed to win the order, never priced.
Customer
The customer is short of cash
Then the risk is not delay but loss.

Check your invoice-to-cash process
- Invoices go out the day goods are delivered or work is done.
- Every invoice carries the PO number, agreed rate, GSTIN, delivery proof and, if you're MSME-registered, your Udyam number and terms.
- Someone calls the customer before the due date to confirm the invoice is approved.
- Overdue invoices are escalated at 7, 15 and 30 days, from the accounts team to the owner.
- Customers past your limit don't get new supplies without approval.

What to do this week
- Rank customers by real days to pay and amount overdue.
- Call the five largest overdue and agree dates in writing.
- Fix the invoice reasons for anything returned.
- Stop supply to customers past your hard limit until they pay.
- Use TReDS or bill discounting where a large buyer's credit is cheaper than your CC.
Short of cash this month? Offer a one-time discount for payment within seven days to your two or three largest, most reliable customers. It's often cheaper than interest or penalties.

Questions owners also ask
How can I get customers to pay on time without losing them?
Send complete invoices on delivery, confirm approval before the due date, escalate politely on a fixed schedule, price longer credit into quotes, and use MSME rights and TReDS where they apply.
Do cash discounts work?
Only for customers who change behaviour because of them. Check who takes the discount and still pays late, and stop it for them.
When should I stop supplying a customer?
When they're past your hard limit and haven't agreed a written payment plan. Every new supply increases the potential loss.
