Custom software and integrations in Charleston, South Carolina
Custom software and integrations for Charleston businesses. Built when off-the-shelf falls short.
Custom software in Charleston County
The missing link for firms that outgrew their tools.
Charleston firms outgrow generic software in specific ways: the booking process that lives in four tools, the property or event calendar that doesn't talk to the books, the status report a big client expects that takes a person a day to build.
The fix is usually smaller than feared: one missing piece, built to fit what's already in place. A booking tool, a client portal, a dashboard that reads your real systems. Built once, on your accounts, maintained by us.
That holds across Charleston County: the peninsula and West Ashley, Mount Pleasant and Daniel Island, James Island and Johns Island, North Charleston, and the barrier islands from Folly Beach to Isle of Palms and Kiawah.

Where we work around Charleston
Charleston, the whole county.
We work with businesses anywhere in Charleston County, on site and remotely. The places below are just where we hear from most.
Served communities in Charleston County, by name: Charleston and its peninsula neighborhoods, Mount Pleasant, James Island, Johns Island, West Ashley, North Charleston, Daniel Island, Folly Beach, Isle of Palms, Sullivan's Island, Kiawah Island, Seabrook Island, and Edisto Island. From Charleston we also serve the surrounding counties: Berkeley County (Goose Creek, Hanahan, Moncks Corner), Dorchester County (Summerville, St. George), and Colleton County (Walterboro, Edisto Beach). Service-area coverage, on site and remotely; our only office is in Clyde.
Downtown Charleston
The peninsula: King Street retail, restaurants, professional firms, and the visitor economy's front door.
Mount Pleasant
Across the Ravenel Bridge: the county's suburban engine, home services, retail, and professional offices serving fast-growing neighborhoods.
West Ashley
Charleston's first suburb, now its own business world: services, retail, and trades along the Ashley River corridors.
James Island
Between downtown and Folly: local services, food, and firms serving island and peninsula alike.
Johns Island
The growth frontier: new subdivisions, farms, and the builders and services following them out Maybank Highway.
North Charleston
The working half of the metro: logistics, manufacturing support, and the firms around the port and the Park Circle revival.
Daniel Island & the barrier islands
Daniel Island, Isle of Palms, Sullivan's Island, Folly Beach, Kiawah, and Seabrook: property services, events, and visitor-facing businesses.
Anywhere in Charleston County, we work with you, and across the rivers in Berkeley and Dorchester counties too.
Examples
What's worth building first around Charleston.
These aren't a limit. They're where the same tasks come up most often.
Hospitality, events & food service
Booking and inquiry tools matched to your real spaces, packages, and calendar, connected to the books and the follow-up.
Construction & trades
Estimating configurators that know your options and margins, producing quotes a customer can approve from their phone.
Professional & technical firms
Client portals where documents get signed, shared, and tracked, and proposal tools that price from your real rates and past work.
How it works
Start. Build. Stay.
Start
We start with the readiness assessment. It's a few questions, and your score is emailed to you with the one gap worth fixing first.
Build
We build the system into how your business actually runs, using the tools you already have where we can, and stay close while your team gets used to it.
Stay
We keep it running, check its work, and show you what it saved and what it earned. We own the architecture. You own the tools. No lock-in, no disappearing act.
Rules to know
AI and data rules in South Carolina.
We found no broad AI law or consumer-privacy law for South Carolina private businesses as of September 2026. Federal and industry rules still apply.
Keep sensitive customer data out of public AI tools unless your vendor contract covers it.
This is a plain-English summary, not legal advice.

Questions
Straight answers.
Who owns what?
Your website, your data, and your accounts live under your logins and stay yours, exportable any time. Krastor owns the automation architecture and agent designs we bring to the work; you license those while we run them. The exact split is in writing before anything is built.
How is this different from hiring a developer?
A developer hands you software and leaves. We build the piece, connect it to the rest of your operation, run it afterward, and report on what it does for the business. If it stops earning, you'll hear it from us.
Do you work with businesses in Charleston and Charleston County?
Yes. Krastor is based in Clyde, North Carolina.
Can you connect our booking system to our accounting so events stop getting retyped?
Yes. That's one of the most common integrations we build here: the booking lands, the deposit posts, and the records match without a second entry.
What happens to our data and accounts if we stop working with you?
They stay yours. We'll hand over a clean export and documentation, and the transition terms are agreed in writing before the build starts, not negotiated on the way out.
