Sila's new feature for turning regular ACH transactions into instant ones using our "Smart Rail" API, /transact.


To Use ACHNow

To use ACHNow, you must use the /transact endpoint. There is no ACHNow support for /issue_sila, /redeem_sila, and /transfer_sila.

With ACHNow, customers can now turn regular ACH transactions into instant ones using RTP and Sila's own proprietary Instant Settlement API, and coming soon: FedNow.

Basic Flow

  1. Transaction submitted via /transact
  2. Sila determines available instant routes on the backend
    1. Customization options to influence rail chosen include fastest or cheapest route and if ACH payments should be sent via Instant Settlement or Same Day.
  3. Rail is chosen
    1. RTP: sent to Trice or other RTP provider
    2. For failures on FedNow and RTP rails, transactions are sent via ACH and settled with Sila's Instant Settlement product or Same Day ACH
    3. FedNow (coming soon): sent to Trice or other FedNow provider
  4. Success!

Why use ACHNow? What are the benefits?

Do you rely on ACH and wish your transactions would get to their destinations faster? Are you wanting to utilize different rails but don't want to build integrations yourself? ACHNow is for you!

Managing the float
Moving money back and forth across providers and rails requires a great deal of orchestration and care. The same can be said for having to manage reserve accounts with each of your partners, and moving money back and forth ahead of transactions.

Sila has signed contracts with banks to manage lines of credit at each bank our providers use, so you don't have to. Are you going to do $1 million in FedNow credits? $2 million in RTP debits? Don't even worry about it.

Ledgering across rails
For Sila customers using ACHNow, a transaction is sent and handled. You call us for the status of the transaction, and so forth. Sila manages the complexity of tracking transaction statuses at our different partners, and makes our management of accounts and funds across partners transparent. You don't need to know the intricacies of how one rail provider's partner bank handles sub-ledgers and roll-up accounting versus another's.

Finding, adding, and managing the rail partners
No one wants to go out and find a partner for each of the rails that is willing to do business, and, longer-term, continue to shop for partners once they've landed a deal. Sila, however, is constantly seeking the best price and will always be attempting to have at least two providers for each rail so that we can force bidding for traffic. No one wants to do that instead of focusing on business, but they do want to see price pressure downwards over time, even as adoption increases.

Optimizing for price
When there is more than one instant payment rail (or more than one provider for that rail) that can take a transaction, we'll be evaluating which one is the cheapest and best. We use end user included minimums (if a client has 1,000 RTP transactions included, we want to make sure they use as many of those free transactions as possible), your stated preferences for time (ie, using Same Day ACH if it is cheaper and the end user specifies it's ok if it takes four hours), and potentially Sila offering incentives to choose one rail or provider over another.

Instant Settlement for ACH
Even where payments can’t go over an instant rail, your account can still settle immediately, and for the few transactions that are returns or encounter other issues, we have processes in place to handle them.
