Replace the spreadsheets, chat threads and apps that almost fit with one system built around how your business actually runs: booking, payments, operations or your own SaaS, on a fixed bid with no hourly billing.
Manual processes work until they don't. Then they cost staff hours, cause mistakes customers notice, and make growth harder.
Orders, schedules and inventory live in shared sheets that break, get overwritten and never agree with each other.
Staff copy details from Messenger to a sheet to an invoice, and every copy is a chance for a mistake.
You pay monthly for several apps, work around what they can’t do, and still can’t get one view of the business.
GCash and bank transfer screenshots checked against records at the end of the day, with no audit trail.
Systems your customers and staff use every day, built for one business rather than for everyone.
Reservations for courts, rooms, appointments or rentals, with live availability and online payment.
One screen for orders, stock, staff and sales instead of a folder of spreadsheets.
Let customers check orders, bookings, memberships or balances themselves, so staff stop answering the same messages.
A first version you can sell, with accounts, billing and the one workflow that proves the idea.
Approvals, job tracking, inspections or requests, with roles so each person sees what they need.
Connect payments, accounting, SMS, email or your existing systems so data moves without copy-paste.
Systems we designed, built or rescued, all in daily use.
Courts were booked by phone and a shared spreadsheet. We built a QR-code booking system where players pick an open court and pay by GCash, with staff verifying payments from an admin dashboard. A database-level constraint makes double-booking impossible, even when two players click at once.
Freelancers were tracking billable work across notes, chats and spreadsheets, then rebuilding invoices from memory. We designed and built Billnox to turn tracked sessions into client progress reports and invoices, with per-client rates and multi-currency billing from day one.
A single missing database write was silently stalling a growing backlog of paid orders on Deal Dunk’s subscription storefront. We traced it across the Shopify and subscription-billing webhook streams, shipped the fix behind a guarded backlog drain, and built their native Shopify Functions app.
You know the price before we start, and you see working software at every step.
We map the workflow on a call, agree what version one must do, and send a fixed-bid quote split into milestones.
You get a working staging link early and see progress at every milestone, not one big reveal at the end.
We test on real devices, launch on your domain, train your team and fix anything that comes up in the first 30 days.
The groundwork that keeps a business system reliable, secure and cheap to run, included where your app needs it.
GCash, Maya, QR Ph and cards through PayMongo, confirmed automatically by webhook.
Owners, staff and customers each see only what they should, with every admin action behind a login.
Rules enforced in the database itself, so two people clicking at once can’t create a conflict.
Works in the browser on any phone, so there’s no app store and nothing for customers to install.
Confirmations, reminders and alerts sent automatically when something happens.
Hosting that scales down when it’s quiet, so you’re not paying for servers nobody is using.
You own the code and the data, with documentation so another developer could pick it up.
Pages built to load quickly on Philippine mobile connections, not just on office Wi-Fi.
How a custom web app compares with spreadsheets and off-the-shelf subscription software.
| Spreadsheets | Off-the-shelf SaaS | dipag.dev custom app | |
|---|---|---|---|
| Fits how you work | You adapt to it | Mostly, with workarounds | Built around your workflow |
| Monthly per-user fees | None | Often | None, just hosting |
| GCash & Maya payments | Manual screenshots | Varies | Built in |
| Prevents conflicting entries | No | Sometimes | Enforced in the database |
| You own the data & code | Yes | No | Yes |
| Changes when you grow | Rebuild the sheet | Wait for the vendor | Extend it |
A clear starting price, then a fixed quote for your scope. No hourly billing and no surprise invoices.
Ideal for ground-up MVPs, complete storefront redesigns, or single major integration migrations — scoped for SME and growing enterprise teams.
Pricing shown in USD — equivalent to our Philippines rates for international clients.
Tell us how it works today. We’ll reply with what version one could look like, a fixed-bid quote and a timeline.
It depends on how many workflows, user roles and integrations version one needs. Our project-based builds have a fixed starting price, shown on this page, and every project gets a fixed-bid quote split into milestones before any work starts.
It depends on how much version one needs to do. We agree the scope and a milestone timeline with the quote, before any work starts, and you get a working staging link early in the build.
For most businesses, a mobile-friendly web app is the better first step: it works on every phone and computer, needs no app store approval, and updates instantly. It can be added to a phone’s home screen like an app.
Yes. We integrate PayMongo so customers can pay by GCash, Maya, QR Ph or card, and each payment is confirmed automatically instead of by checking screenshots.
Yes. The code, the database and the hosting accounts are yours. We document the system so you’re never locked in to us.
Every project includes 30 days of post-launch fixes. After that you can bring us back for new features per project, or keep us on a monthly retainer for ongoing work.
Mostly Next.js, React, TypeScript and PostgreSQL, hosted on Vercel. It’s a widely used stack, so the app is fast, secure and easy for other developers to work on.
