Software built for how Philippine businesses actually operate.

We build configurable systems for small and medium businesses. One engine, set up per client, running in pilot now.

Selected work

Small businesses here take bookings through Facebook and Messenger, then copy them by hand into a calendar. Things get missed. Tala collects those bookings into one place and keeps the calendar straight, so the owner enters a booking once and the rest follows.

Two pilots are underway, both live builds with real owners rather than demos. Results are not in yet, and we will publish them when they are.

Visit tala.core4sys.com

Public site for a travel company working in Sagada and across the Cordillera, covering their journeys and the Learning Together drive that connects supporters with communities asking for school supplies and computers.

No payments run through it, by choice. Supporters register their interest and an organizer follows up personally. A separate site handles rider registration for the Dakiwas Tour, their guided ride across the Cordilleras in September 2026.

Front desk system for a homestay in Sagada, Mountain Province. It prices a stay from the dates, rooms, and guests, applies senior, PWD, and child discounts, and checks for room conflicts before anything is confirmed. Confirmed bookings are written to the Google Calendar the family already keeps, so the desk and the calendar cannot drift apart.

Rates, discounts, and the required downpayment are edited from the dashboard, so a pricing change does not need a developer.

How we work

Configure, do not rebuild

One engine covers catalog, intake, tracking, and records. A campsite and a tour operator run the same system with different settings, so the second client costs a fraction of the first.

Start with a pilot

We count what the manual process actually costs before quoting anything, run a short pilot against that baseline, and review it with you before either side commits further.

Keep the channels you use

Facebook and Messenger stay. Customers keep messaging the way they already do. The system organizes what comes through so nothing is lost between the chat and the calendar.

The company

Core4 Systems is a small software company in the Philippines. Four founders cover the build, operations and client work, infrastructure, and legal and internal setup. We are early, and we would rather say so than pad this page.

We take on work where the software has to fit a business that is already running, not the other way around. That means understanding the current process first, including the parts held together by hand, and building only what replaces them.

Tell us what you run.

Send a short note about the business and how bookings or orders reach you now. We will tell you honestly whether this is a fit.
