Timing

Each business day, Column offers six 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. The Fed processes 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 Deadline	Target Settlement
7:15am PT	5:30am PT - next business day
11:30am PT	5:30am PT - next business day
1:30pm PT	5:30am PT - next business day
4:45pm PT	5:30am PT - next business day
7:30pm PT	5:30am PT - next business day
11:00pm PT	5:30am PT - next business day

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

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

API Request Deadline	Target Settlement
7:15am PT	10am PT - same day
11:30am PT	2pm PT - same day
1:30pm PT	3pm PT - same day

Creating same day transfers with the API

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

The ACH must be submitted to Column no later than 1:30pm PT.
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.

Submission Time (PT)*	`same_day`	`effective_date`	Processed as same day?
Before 1:30pm	true	null	yes
After 1:30pm	true	null	no
Before 1:30pm	null	today	yes
After 1:30pm	true	today	no
Before 1:30pm	null	null	no
Before 1:30pm	false	today	no
