Key Takeaway: Bring your own processor (BYOP) is a mortgage processing model where a broker’s existing processor joins Willow Processing and keeps working the broker’s files. The processor is paid through the processing fee disclosed on the Loan Estimate instead of the broker’s payroll. Willow charges a flat $395 per file, and the processor receives the rest.
Every growing brokerage hits the same processing question eventually. You have a processor who knows your files, your borrowers, and the way you like to work. They’re one of the best hires you’ve made. But their salary, payroll taxes, and benefits sit on your P&L every month, whether you close ten loans or two.
Most brokers assume they have two choices: keep carrying that cost or switch to contract mortgage processing and start over with someone new. There’s a third option that lets you keep the processor you trust while taking the cost off your books. It’s Willow’s BYOP program: bring your own processor.
This guide explains how BYOP works, how it compares to in-house and third-party mortgage processing, and how to tell whether it’s the right fit for your business.
A processor’s salary is only the starting point. Once someone is on your payroll, you’re also paying for:
Add it all up, and the real cost of an in-house processor is usually well above their salary.
Downtime is the biggest problem. Processing volume moves with rates, seasons, and the market, but an in-house processor’s cost stays the same. That fixed cost gets spread across however many loans you close that month. In a busy month, it’s spread thin. In a slow month, each closed loan carries a much bigger share of it. If your volume drops by half, your processing cost per loan roughly doubles, even though you’re paying the same person for the same quality of work. In a slow stretch, that can squeeze your margins hard.
You also carry the coverage risk. When your processor is sick, on vacation, or buried during a refi wave, there’s often no one to step in. Files slow down, borrowers get frustrated, and you end up doing processing work yourself instead of originating.
When processing costs start to pinch, most brokers weigh two familiar paths.
Keep processing in-house. You keep full control and a dedicated relationship, but you also keep the fixed cost, the payroll administration, and the risk of having no backup when your processor is out or volume spikes.
Switch to contract mortgage processing, you pay per file instead of carrying a salary, and a team stands behind every loan. Third-party mortgage processing scales up and down with your pipeline, which makes it a strong fit for brokers without a processor or those who’ve outgrown one. The trade-off is that you’re building a new working relationship, and if you already have a great processor, you’d be letting them go.
For brokers who are happy with their processor, neither option feels right. That’s the gap BYOP fills.
BYOP, bring your own processor, is a model where your existing processor joins Willow’s team while continuing to work your files. You keep the relationship. Willow takes on the cost structure and the administration.
With Willow’s BYOP program, it works like this:
For you, the broker:
Your processor keeps the same relationship and the same files, now backed by Willow’s setup, disclosure, and post-closing teams. It’s the relationship of an in-house processor with the cost structure of contract mortgage processing.
BYOP isn’t the right move for every broker. It works best in a few specific situations.
BYOP is likely a strong fit if:
Contract processing may be the better fit if:
A quick gut check: If losing your processor tomorrow would hurt your business, but paying their salary in a slow month also hurts, BYOP was built for you.
Either way, it helps to work with a third-party mortgage processing company that offers both, so you can choose the model that fits today and adjust as your business changes.
Willow Processing is the first processing company to offer BYOP, changing how brokers think about contract processing companies. Here’s what sets Willow apart.
Built for brokers. Willow focuses on serving mortgage brokers and is a UWM Preferred Processor. We also partner with AIME and NAMB, two of the leading organizations in the broker channel.
No new systems to learn. Willow works directly in Arive and LendingPad, so your processor can keep working the way they already do and your workflow stays the same.
Speed your borrowers will notice. Same-day disclosures are standard, which keeps loans moving and makes a strong first impression on your borrowers.
A full team behind every file. Every file is supported by dedicated setup, disclosure, and post-closing teams. Your processor gets to focus on moving loans forward instead of handling every step alone.
Room to grow. Willow is licensed in 35 states, so as your brokerage expands into new markets, your processing can come with you.
Support for your processor, too. Processors who join through BYOP get supportive onboarding plus ongoing training and coaching, so they keep building their skills while working your files.
Trusted by brokers. Willow has more than 275 five-star Google reviews from brokers and processors who’ve worked with our team.
Flexible options as your business changes. Because Willow offers both BYOP and contract mortgage processing, you can choose the model that fits today and change it later without switching companies.
You shouldn’t have to choose between a processor you trust and a cost structure that works. If you’re carrying a processor’s salary today, bring your own processor to Willow and see what changes.

What does BYOP mean?
Bring your own processor, or BYOP, lets a mortgage broker keep their existing processor while that processor works through Willow instead of on the broker’s P&L. The broker keeps the relationship, and processing moves off their payroll.
How much does Willow’s BYOP program cost?
Willow charges $395 per file. The rest of the processing fee goes to your processor.
How is BYOP different from contract mortgage processing?
With contract mortgage processing, Willow’s processors work your files. With BYOP, your own processor keeps working your files, with Willow handling administration and providing team support.
Will my processor still work on my files?
Yes. Your processor keeps working your files and your borrowers, just as they do now. The difference is that they now have Willow’s setup, disclosure, and post-closing teams behind them.
Who sets my processor’s compensation?
You do. You set your pricing and your processor’s compensation. Willow takes its flat $395 per file, and your processor receives the rest of the disclosed processing fee.
How is my processor paid?
Your processor is paid through the processing fee disclosed on the Loan Estimate, not through your payroll. That’s what moves processing costs off your P&L.
Does my processor need to learn new software?
Willow works directly in Arive and LendingPad, so if you’re already using one of those platforms, there’s no new system to learn for your processor.
How do I get started with BYOP?
