What we build

If your team does it 100 times a month, it can be an app.

We build the kinds of tools software companies sell as “SaaS” — but tuned to exactly what your business needs, with no monthly subscription fees forever.

Booking & scheduling apps

Custom appointment, class, or service booking systems with the rules your business actually uses — no off-the-shelf compromises.

Plan a booking app

Internal dashboards & reporting

Pull data from your tools into one place. KPIs, sales pipelines, operations dashboards — the screen your team actually opens every morning.

Scope a dashboard

Customer portals & logins

Give clients a place to log in, see status, upload files, pay invoices, or self-serve — saving your team hours every week.

Design a portal

Workflow automation tools

Replace spreadsheets, sticky notes, and copy-paste with apps that run your workflow end to end — quotes, orders, follow-ups, approvals.

Map your workflow

Back-office tools

Custom admin tools tuned to how your team actually works — inventory, jobs, dispatch, scheduling, anything that lives in Excel today.

Scope an admin tool

Productize a service

Got a repeatable service you wish ran itself? We’ll turn the workflow into a web app you can either run yourself or sell as your own SaaS product.

Build your product

Why custom

Why build instead of subscribe to SaaS?

Off-the-shelf SaaS is great until it isn’t. Here’s when a custom app pays off.

No more $200/seat/month forever

Pay once to build the app, own it forever. Compare that to SaaS subscriptions that grow with your headcount and never stop.

Built for your workflow, not the average user

Off-the-shelf SaaS forces you to adapt to its way. A custom app fits your process exactly — the way your business actually works.

You own the data and the code

No vendor lock-in. No surprise price hikes. No risk of the SaaS company shutting down or changing terms. Your app, your rules, forever.

Real integrations with your real stack

Connect to QuickBooks, Stripe, HubSpot, Slack, your existing WordPress site, or whatever else you use — no waiting for a vendor to add support.

How it works

From idea to working app in four steps.

  1. 01

    Free 30-minute discovery call

    Walk us through the workflow you want automated. We’ll tell you on the call whether a custom app is the right answer — sometimes a plugin or a Zapier flow does the job for less.

  2. 02

    Fixed-scope proposal in one week

    Written scope, fixed price, delivery date, and a clickable wireframe of the core screens. You see exactly what you’re buying before you commit.

  3. 03

    Build sprint (4–12 weeks)

    Weekly demos and a staging URL you can actually use. You shape the app as it’s built. No big-bang reveal at the end.

  4. 04

    Launch, train, and support

    We deploy, hand over the code, train your team, and stay on retainer for updates, bug fixes, and new features as the business grows.

Common questions

Before you book the call.

Often, yes. If you’re paying $200–$500/seat/month for SaaS with 5+ users, a one-time custom build typically pays for itself in 12–24 months — and the savings compound forever after. We’ll do the math with you on the discovery call.
Simple tools ship in 2–4 weeks. Most custom apps take 6–12 weeks. Complex multi-tenant SaaS products run 3–6 months, phased so you see value early.
Weekly demos exist exactly for this. Most projects evolve as you see the app in action. Small adjustments are part of the build; large new features get a separate quote so you stay in control of scope and budget.
Yes — you own your copy. You get the source code, database schema, design files, hosting credentials, the works. No vendor lock-in; take it to another developer any time. Trendwise also retains a non-exclusive license to reuse the underlying code, components, frameworks, and architecture in other client projects or our own products. Your business data, customer lists, brand, and proprietary content stay exclusively yours. Need exclusive IP? We offer that as a paid add-on — ask us for a quote.
Almost always. We connect to QuickBooks, Stripe, HubSpot, Salesforce, Zapier, your WordPress site, Google Sheets, Slack, and any tool with a REST API. If the integration doesn’t exist, we build it.
Every project includes 30–90 days of post-launch support. After that, monthly care plans cover hosting, security updates, bug fixes, and ongoing feature development as your needs evolve.
