5 invoicing mistakes costing Sri Lankan SMEs money
We talk to café owners, retailers and freelancers across Sri Lanka every week. The same five invoicing mistakes come up again and again - and each one quietly costs real money.
1. Not sending the invoice immediately
The single biggest predictor of getting paid on time is how quickly the invoice goes out. Every day between finishing the work and sending the bill is a day added to your payment cycle. If your invoices wait for "when I get to the computer", they wait too long.
Fix: send the invoice from your phone the moment the job is done.
2. No record of what's been paid
A drawer full of carbon-copy books tells you what you billed - not what's been paid. Businesses routinely lose track of two or three unpaid invoices a month, and chasing them three months later is awkward at best.
Fix: track every invoice with a status - paid, sent, overdue - and review the overdue list weekly.
3. Forgetting VAT until filing time
If VAT isn't captured on each invoice as you go, someone has to reconstruct it at filing time from memory and receipts. That's a weekend gone, and errors are expensive.
Fix: put VAT on the invoice itself, calculated automatically.
4. Handwritten totals
Arithmetic mistakes on handwritten bills cut both ways: undercharge and you lose margin, overcharge and you lose the customer's trust.
Fix: let software do the maths - line items, VAT and totals.
5. No paper trail for quotes
A price agreed on the phone is a price disputed later. When the quote and the invoice are separate pieces of paper (or no paper at all), disagreements are inevitable.
Fix: send a written quote first, then convert the same quote into the invoice - one click, no re-typing, no dispute.
