Frequently asked questions

How do I calculate equal instalment payments?

Monthly payment = Total amount ÷ Number of months. For interest-bearing plans, use: Payment = Principal × r(1+r)^n ÷ ((1+r)^n − 1) where r = monthly rate.

Should I charge interest on payment plans?

Many service businesses offer interest-free plans for 3–6 months to improve affordability. For longer terms, a small admin fee or interest rate is common.

How do I track payment plan instalments?

Use Tregovia's billing module to create split invoices, track each payment, and send automatic reminders for upcoming instalments.
