Offering finance options at point of sale

Hola to all

I currently run an Instagram page selling premium branded clothing. Customers are asking to spread the cost over a payment plan.

What options do i have?
Anyone know companies offering point of sale finance?
Anyone know any solutions to spread costs over a period of time?

If anyone has anything that could help, please feel free to share!

Thanks for giving it a thought even if you don’t respond
