Prior to the merger, CTMLS Members were normally billed on a 6 month basis and GFC CMLS members were billed on a quarterly (3 month) basis.
With the merger that took place August 1st, all members were billed in September 2017 on a 3 month cycle for the amount of $78.78 ($26.26 per month) for August-Oct. This was the first official billing as SmartMLS.
Going forward, you will only receive invoices on a 6 month basis from SmartMLS (November through April and May through October). The amount of $157.56 that was invoiced 11/20/17 is for the MLS dues for our 6-month billing cycle of Nov 2017-April 2018. If you purchase a Key from SmartMLS, your Key is billed separately from the MLS dues and invoices will also go out on a 6 month basis (at the same time as the MLS Fees).
The date you join the MLS will determine what you will be billed. We do not prorate dues- you pay for the full month regardless of when you join during that month.
