Questions

Is Sumocat a good Square Invoices alternative?

If you invoice from an iPhone and want payments in your own Stripe account, yes. If you take most payments in person with Square hardware, Square Invoices keeps everything in one account.

Can I split a job into milestone payments for free?

Yes. Add a deposit and milestones to an estimate in Sumocat, and each part becomes its own invoice when it is due. The parts always add up to the exact total.

Does Sumocat take a fee on card payments?

No. With Sumocat Pro, clients pay from the invoice link through your own Stripe account. Stripe charges its usual fees and Sumocat adds no fee of its own.
