From inbound manifest
to customer sign-off.
From warehouse floor
to job site.
From work order
to paid invoice.
The Castle Suite is the operations platform for commercial installation companies — receive goods into a warehouse, manage a field crew, and deliver and install at the customer site, all in one system.
Start with Keep and Raven. Add Garrison when you're ready. Build your Castle.
One suite, six modules
Adopt what you need now. Every module speaks to the others out of the box.
Raven Your fleet, always in sight
Plan routes and assign vehicles by crew, then track every delivery live from dispatch to drop-off. Crew leads confirm completion on-site, reverse-logistics runs handle haul-away and disposal billing automatically, and a failed delivery preserves a full record — including whether the delay was on you or the customer — so nothing falls through the cracks on a reschedule.
Keep Everything in its place
Every item lives on a real location tree — facility, area, rack, shelf, bin — not a spreadsheet guess. Receive against an inbound manifest, allocate stock to a project, and combine components into finished assemblies, whether that's a reversible modular grouping or a one-way custom build, with full component traceability either way.
Garrison Deploy your crew with confidence
An open, Scrum-style task board lets any qualified crew member pull the next job — prebuild, staging, loading, or install — with certifications and safety requirements gated automatically. Crews log time and photos in the field, capture customer sign-off on the spot, and payroll hours export cleanly to Gusto, ADP, or QuickBooks.
Ledger Get paid faster
Bill a project the way it actually gets paid — deposit, progress, milestone, or final — with phase checkpoints and retainage built in, not bolted on. Field crews can flag an on-site upsell or disposal fee for the office to review and invoice, and every credit or deposit applies against a running balance you can always audit.
Steward Keep the pipeline full
Keep purchase orders, supplier terms, and distributor stocking requests in one queue instead of scattered emails and spreadsheets. Every PO gets a real sequential number per tenant, and accepted stocking requests from a partner network flow straight into your own inbound expectations — no manual re-entry.
Envoy Your client's window into every job
Give customers and resellers a branded, no-login window into their own jobs — status, invoices, and sign-off — with visibility you control per relationship. A distributor sees what you allow; their end customer sees only what you allow them, and disputes route back to your team instead of getting lost in an inbox.

About Us
Software built by people who understand the work.
Castle Systems is a software company based in Pacific, MO. We build the Castle Suite, the operations platform for commercial installation companies, and we also take on custom application development and software optimization work for businesses that need something built or improved beyond the box.
We started the Castle Suite because installation companies — the crews that receive freight, stage it in a warehouse, and get it installed on-site — were stuck running that work across spreadsheets, texts, and paper. We built the platform we wished existed: one system from inbound manifest to customer sign-off, priced so a small shop can actually afford it. We keep our own overhead lean and pass that along — no enterprise-software price tag for a five-person crew, and no per-module surprise fees once you're in.
