About Synterra
Synterra Limited is a company registered in Papua New Guinea, based in Port Moresby. We build and operate financial services designed for the realities of the PNG workforce — starting with BuyNau.
BuyNau
BuyNau is a salary-linked loan and credit service for employees of our partner employers. Rather than relying on informal, high-cost lenders, employees can apply for a transparent short-term loan directly from their phone, with repayment arranged through their employer's payroll.
How it works
Verify
Sign in to the BuyNau app, complete your profile, and verify your identity and employment.
Apply
See your eligible amount, interest, fees, and full repayment schedule before you accept anything.
Repay by payroll
Repayments are deducted automatically from your salary by your employer's HR on each pay date — no cards, no manual transfers.
Repayment is payroll-only
BuyNau never takes card auto-debits or direct debits. Every repayment is made exclusively through payroll deduction arranged with your employer's HR department, on the schedule you agreed to when you accepted the loan.
