SplitRun vs Twill: flat price or a share of your volume?

Twill is the newest of the platforms an ISO will find when searching for residual software, and the most ambitious. It sets out to run the whole office, with AI at every stage, and it charges for that as a percentage of the volume your merchants process. SplitRun does one thing in that list, residuals, and charges a flat monthly price that is on the website.

We make SplitRun. Everything here about Twill comes from its own website, twillai.com, read on September 28, 2026, and we link to it so you can check. Twill is moving fast, and if something below is out of date we would rather correct it than argue.

The short version

What Twill does that SplitRun does not

Twill is a broad product, and for an office that wants all of it, breadth is the point.

• It covers the whole lifecycle. Twill's site lays out four stages. Sell, with pre-call merchant profiling, a solutions engine, processor matching and call transcript intelligence. Onboard, with a white-label merchant portal, pre-populated applications, AI approval scoring and document analysis. Activate, with milestone-triggered outreach, terminal and gateway guides and first-transaction tracking. Manage, with a multi-processor view, risk and churn alerts, residual verification and sub-agent visibility. See Twill.
• It connects to processors directly. Twill names TSYS, Fiserv, Global, Elavon, Maverick, Kurv, Priority and North, and describes connecting for application submission, onboarding and live data, not only residual files.
• AI runs through it. Approval scoring, validation, call intelligence and churn alerts are described as AI features rather than add-ons.
• Its pricing rises and falls with you. Twill's own comparison article puts it as a percentage of processing volume, "aligned with ISO economics", and says Twill earns when you earn. For a young office with little volume, that can mean a low bill at the start.

If you are boarding merchants every week, want applications, activation and residuals in one system, and like the idea of a vendor whose fee tracks your growth, Twill is built for that and SplitRun is not a substitute.

Why SplitRun is the simpler choice for residuals

Most owners searching for residual software are not shopping for an operating system. They have one problem: month-end takes days, agents argue with the numbers, and nobody fully trusts the spreadsheet. A platform is a large answer to that question. SplitRun is the right-sized one.

• You know the price before the call. SplitRun is $49, $149 or $299 a month depending on the size of the book, on the pricing page, with usage above a plan's limits billed per active agent or merchant. Twill does not publish its rate. A percentage of volume also means the fee grows with your merchants' sales rather than with the work the software does. A book that doubles its volume pays double, whether or not month-end got any harder. Before you sign, ask for the rate in writing and multiply it by a typical month's volume, then compare that with a flat number.
• It is built like modern software, for one job. No modules to configure and no training course. You upload the reports the processor sent you, SplitRun reads them, and the month is calculated. When a layout changes or a new processor arrives, AI-assisted mapping proposes the columns and you confirm them. Month-end is load, check, publish. See the monthly workflow.
• Nothing else in the office changes. SplitRun asks for the residual reports you already receive and your agent agreements. Your CRM, your boarding process and the way you pay agents stay where they are. There is no migration, and no processor connection has to be set up before your first month is calculated.
• Every agent gets a login, and it hides the right things. Agents see their own merchants, earnings, adjustments with reasons, and their history month over month. They do not see commission rates, the house margin or other agents' numbers. The reasoning is in Agent commission transparency.
• It tells you what the residuals mean. SplitRun flags merchants whose profit has fallen two months running, shows how concentrated the book is across merchants and agents, compares processors on profit per merchant, and lets you test a comp plan change against real past months before you announce it. Twill describes risk and churn alerts and a multi-processor view. It does not describe comp plan scenarios or concentration analysis on its public pages. See merchant attrition warning signs, portfolio concentration, which processor pays best and comp plan modeling.
• Months are locked when published. A statement an agent has seen does not change afterwards. Corrections appear as corrections in a later month, with a reason.

What we cannot compare

Twill's public pages do not state its rate, describe an implementation timeline, or say whether agents get their own login or see their numbers through the ISO's view. We are not going to guess at any of those. Ask them directly, and ask the same of us.

Can you use both?

Yes, although it is less natural than pairing SplitRun with a plain CRM, because Twill includes residuals. Some offices will want Twill for selling and onboarding and still prefer a residual tool whose price is flat and whose agent portal is deliberate about what it hides. SplitRun works from the processor's files, so nothing has to be integrated for it to run alongside anything else.

What SplitRun does not do

• No lead management, merchant profiling or call intelligence.
• No merchant applications, approval scoring, boarding or activation tracking.
• No direct processor connections. SplitRun works from the report files the processor sends you.
• No ACH payouts. SplitRun produces the payroll summary; you pay agents the way you do today.

If any of these is why you are looking, Twill or another ISO platform is the better fit.

How to decide

1. Name the problem. "Month-end takes days and agents argue with the numbers" is a residuals problem, and SplitRun is built for exactly that. "We want one system from the first call to the residual" is a platform decision.
2. Get Twill's rate in writing and do the multiplication. A percentage of volume is only cheap while volume is small. Compare a typical month, and a month two years from now, with a flat price.
3. Test with your own reports. Either product should take last month's files and reproduce what you actually paid. Ask both, and note how long each takes to get there.
4. Ask what your agents will see, and show one agent.
5. Ask what happens when a rate changes mid-year, and whether last month's statement can still be reproduced afterwards.

Frequently asked questions

What is Twill? Twill describes itself as the operating system for payments ISOs. Its site lays out four stages, Sell, Onboard, Activate and Manage, with AI at each, and names eight connected processors. Residuals sit inside the Manage stage, with file import, AI validation and payout routing.

How much does Twill cost? Twill does not publish a price list. Its own comparison article says it charges a percentage of processing volume, so the fee rises and falls with your merchants' sales. We do not know the rate and will not estimate it. SplitRun's pricing is public and flat: $49, $149 or $299 a month plus usage above plan limits.

Is a percentage of processing volume a good way to pay for software? It depends on your book. It keeps the bill low while volume is small and lets the vendor grow with you. It also means the fee tracks your merchants' sales rather than the work the software does, so a book that doubles its volume pays double. Ask for the rate, multiply by a typical month, and compare with a flat price.

What is the main difference between Twill and SplitRun? Scope and pricing. Twill is a whole-lifecycle AI platform priced as a share of volume. SplitRun is residual-only software at a flat public price, with a portal for every agent and analytics on top of the calculation, and it runs without changing anything else in your office.

Can I use SplitRun alongside Twill? Yes. SplitRun works from the processor's residual reports and your agent agreements, so it runs alongside any platform without integration. Whether that is worth doing depends on how much you value flat pricing and SplitRun's agent portal and analytics over Twill's built-in residuals.

What are the alternatives to Twill? NMI Merchant Central (formerly IRIS CRM) and ISOhub are other full platforms for ISOs. SplitRun and Fullcast are residual-focused tools. We describe each in ISO residual management software compared and compare the others directly in SplitRun vs ISOhub, SplitRun vs Fullcast and IRIS CRM alternative.
