Frequently asked questions
How do I create a payment schedule in Flows ERP?
On the contract, enter the amount, the number of periods, the credit term or start date, the interest method, and any down payment, then click generate. The full schedule appears with amounts and due dates, and you can adjust it before saving.
Which interest methods are supported?
Flows supports four methods: equal principal, equal installments on a reducing balance, a flat rate on the original amount, and interest-free credit terms. You choose the method on each contract.
Can a plan include a down payment?
You can add a down payment when you enter the terms. The remaining periods are then calculated on the balance that's left.
Can we edit a plan after it's saved?
Plans can be edited after saving, for example after you renegotiate with a customer. Every change is recorded, so you can still see how the plan looked before.
Do purchase contracts work the same way?
Payment plans on purchase contracts work just like those on sales contracts, with the same methods and reminders. The only difference is that the money goes out instead of coming in.
What happens when a period isn't paid?
For customer payments, the overdue period moves into the collections module for follow-up, with penalty interest if you use it. For supplier payments, the period keeps reminding you until it's paid.
