Each business day, Column offers five API request deadlines synchronized with Federal Reserve settlement windows.

ACH Business Days

While Column is open 24/7, 365 days a year, the ACH system at the Federal Reserve is not. They process FedACH transfers Monday-Friday excluding these holidays.

FedWire has its own business hours. See the wire section for specific timing information.

Standard Timing

By default, Column sends ACH requests using standard timing. This means that, regardless of when the ACH is created, it will settle no later than the opening of the following business day.

API Request DeadlineTarget Settlement
7:15am PST5:30am PT - next business day
11:30am PST5:30am PT - next business day
1:30pm PST5:30am PT - next business day
4:45pm PST5:30am PT - next business day
11:00pm PST5:30am PT - next business day

It's possible, but not guaranteed that funds will arrive sooner than the Target Settlement.

Same Day Timing

Column allows you to send ACH transfers same day, provided they are submitted before the last API request deadline (1:30pm PST). ACH transfers submitted after the deadline will automatically be sent with standard timing.

Creating same day transfers with the API

To send an ACH same day, it must meet the following criteria:

  1. The ACH must be submitted to Column no later than 1:30pm PST.
  2. The ACH must set same_day = true and/or effective_on = today.

*If same_day = false, ACH will be sent with standard timing regardless of effective_date.
