We built FluxIsSpark because invoice chaos was killing productivity

Back in 2023, we watched businesses drown in manual invoice processing. Teams spending hours on data entry. Payments getting delayed because someone misplaced a PDF. Finance directors pulling their hair out over approval bottlenecks.

That's when we decided to do something about it. Not with flashy promises or overcomplicated systems. Just solid automation that actually works.

Started small, grew intentionally

We launched in early 2024 with three clients and a straightforward goal: make invoice processing less painful. Our first system handled maybe 200 invoices a month. Nothing fancy.

But here's what happened — those clients told their colleagues. And their colleagues had the same problems. Late approvals, missing documentation, manual reconciliation eating up entire afternoons.

By mid-2024, we were processing thousands of invoices monthly. We added OCR capabilities in June. Integrated with major accounting platforms by September. Each feature came from actual client requests, not a generic roadmap.

Now in 2025, we're handling invoice workflows for companies across South Korea. Manufacturing firms, service providers, import-export businesses. The problems look different on the surface, but they all boil down to the same thing: too much manual work, too many opportunities for mistakes.

We're based in Goyang, which keeps us grounded. No Silicon Valley hype here. Just a team that shows up, solves problems, and goes home knowing we saved someone a few hours of tedious work.

What drives us daily

These aren't corporate values printed on a poster. They're how we actually make decisions when things get complicated.

Clear over clever

We could build the most sophisticated system imaginable. Instead, we build systems people understand in five minutes. Because if your accounting team can't figure it out quickly, what's the point?

Real problems only

We don't add features because they sound cool. Every capability we build solves something that actually bothered a client. That's why our system feels practical rather than bloated.

Support that picks up

When you call us, a person answers. Not a chatbot, not a ticket system. A real person who knows the system and can help right then. We think that's how business should work.

The people behind the system

We're a small team, which honestly works better. Everyone knows what everyone else is doing. When a client has an issue, whoever's available jumps on it. No bureaucracy, no passing the buck.

Taejun Voss

Technical Director

Built the core processing engine and still writes code daily. Used to work at a fintech company and got tired of watching good automation ideas die in committee meetings. Now makes sure our system actually does what clients need.

Siobhan Dreher

Client Operations Lead

Handles implementation and makes sure new clients get up and running smoothly. Spent years in accounting before switching to tech, so she knows exactly where invoice processing breaks down. Clients usually end up asking for her specifically.

How we actually work with clients

Understanding your current mess

We start by looking at how invoices flow through your business now. Where do they come in? Who touches them? Where do things typically get stuck? This takes a few hours, not weeks.

Setting up the basics

We configure the system to match your approval chains and accounting structure. Then we run a parallel test with real invoices. If something doesn't work right, we fix it before you're fully live.

Training your team properly

We sit with the people who'll use this daily and walk through everything. Questions come up, we answer them. Usually takes an hour or two, and then they're comfortable.

Staying available afterward

First month, we check in regularly. After that, we're a phone call away whenever you need us. System updates happen automatically, but we always test them first with existing clients.
