Online rental payment late fees

[Chris G.]

Is anyone using an online rental payment app/site that they like that has the ability to do late fees.  My leases state a $50 late fee after the grace period and then $5 a day there after.  I was using erentpayments.com (we all know how that worked out) and it allowed you to implement this but now I'm using apartments.com (formerly cozy) and it only let's me do a flat late fee and not a daily late fee as well.  Our tenants who were previously incentivized by the daily late fee have been getting a little lax and realized that the daily late fee no longer is added by the new system and therefore are taking a little longer to pay when late.   I've looked into turbotenant.com but they only offer daily late fee OR flat rate, not both.  Any ideas?
