fiat payment

Requirements

• Remove VMs and IPs from quota
• Remove quota and introduce balance and voucher balance for user
• VMs will have a state (in progress, success, failed)

Payment scenario

Vouchers

• user model will have a voucher balance can be used to deploy
• Voucher balanced is charged only from vouchers
• when a voucher is applied, voucher balance should be updated
• Once user has applied a voucher we should settle pending payments (invoices)
• Check If voucher user has enough money to continue his/her deployment (If no we should inform her/him that we will delete the VM after x months)

Admin

• Admin will set prices for vms and k8s
• list all invoices

Periodic Invoices

• User can get, pay an invoice
• support balance, voucher and card methods to pay invoices and the ability to mix between them
• User can list invoices
• Every month, we should create an invoice for each user with active deployments (containing all vms consumed during the month)
• Invoices are charged from balance
• If no balance? invoices are paid from user default payment method - If no card balance? use another card
• If no default card for user, check all user cards
• Settle invoices according to their total cost (sort)

Cards

• Each user should add valid card
• cards should be unique
• we should verify cards (I think stripe do?)
• Old users should provide their credit card too, except they use vouchers
• user cannot delete all cards while having active deployments
• Add an option to add more than one credit card
• User can list his cards
• User can set default card
• Once user has added a new card we settle pending payments (invoices)

User can deploy?

• When user has a valid card
• When user has enough voucher balance (excluding other active deployments)

VMs price increase

• If an admin increased the price of a vm, old vms should be paid according to its old prices
• new vms should be paid according to new prices
• save prices with each deployment

Balance

• Each user can charge his balance
• Once user has charged his/her balance we settle pending payments (invoices)
• Debt balance is updated every month with total usage of deployments

Delay

• If the user didn't pay for his/her deployment - no credit (we will remove it after 3 months)
• If the user didn't pay for his/her deployment (no credit), a reminder email will be sent every week including his invoice

Notes

• DB will record vms/hr used per user
• VM/K8S will have around 6 items (small/medium/larger with/without public IP)

Investigation

• stripe usage
• alternative API

Questions

• should I allow user to delete Invoices? (No)
• what if user with voucher money didn't delete the vm at the end of the month? should we delete it? (After grace period we will delete it)
• should we add if invoice paid using voucher balance?
• should we check debts on adding cards?
• should we add customer support chat?
