When no SaaS fits — we build the software (and the screens) your business actually runs on.
Most software problems get solved by buying something: a CRM for pipeline, a helpdesk for tickets, a dashboard tool for reporting. Custom software is what’s left when nothing off-the-shelf fits — the workflow is specific enough to your business that forcing it into a generic tool means working around the tool instead of doing the job. That’s the build AutoJet does: software shaped around your actual process, whoever uses it — your customers, your own team, or both on the same system.
Our default stack is Svelte on the frontend and Supabase for auth, the database, and file storage — Postgres Row Level Security enforces who sees which rows at the database layer (a customer their own account, a fulfillment team their own queue), and Supabase Auth handles sessions so we’re not hand-rolling login in week one. If your engineering team already owns a stack, we build against that instead — a custom system has to be one your team can maintain long after we’re gone.
Fixed price, fixed scope. We agree on the first shippable version before writing code, ship it, and treat anything discovered afterward as a scoped follow-on with its own price — not quiet scope creep folded into the original estimate.
Off-the-shelf vs custom, in practice
A SaaS or CRM that covers most of the job. The rest — your actual bottleneck — gets worked around with a spreadsheet, a Zapier hack, or someone’s memory.
Software shaped around the exact workflow instead of the other way around. A customer logs in through Supabase Auth to a screen scoped by Row Level Security to their own account; your own team gets the same pattern scoped to their role — both against live data, not a synced copy that’s already stale.
We don’t build a company-wide platform on spec. We scope the exact workflow no off-the-shelf tool covers, and ship that.
How custom software ships
Find the gap → fixed scope → design the path → build against live systems → hand over ownership.

Built on the stack you can keep
Default stack for speed — or yours, if your team already owns one. Either way, you maintain it after handoff.
Anatomy of a shipped build
One shape this takes: a self-serve flow. Login → the job → done. Happy path finishes without your team. Fail path escalates with context — not a dead end.
Query hits live CRM/billing data behind Row Level Security — status, reschedule, invoice
Escalates with the account ID and what they were doing — not a dead “email support” link
When this makes sense
Design isn’t a phase we bolt on after engineering starts. We map the real path first — whoever’s using it, customer or your own team — so a screen reflects a decided flow, not a template CRUD form with your logo on it.
Most builds read live from systems you already run: the CRM stays the source of truth for account data, billing APIs report real payment state, internal databases stay the record — not a nightly sync job that’s already a day stale by the time anyone opens the screen.
This is the build for a real platform — multiple roles, multiple surfaces, maybe customers and your own team on the same system. If the whole requirement reduces to one person’s one recurring job, that’s a smaller, cheaper build — see Internal tools instead.
From our work
A road-transport business ran billing and payment reconciliation entirely in Excel: trucks run trips for transporters, trips get billed, and payments come back partially and out of order — one transfer covering several bills, part now, the rest next month. The sheet had a structural flaw: a blank cell silently zeroed out a trip's amount, and matching a payment to the trips it actually covered meant scrolling and memory. We built a fixed-price billing app around the real shape of the problem — bill entry that mirrors the sheet they already knew, payment matching at the trip level (not the bill level, since that's how transporters actually pay), and a dashboard for what's still pending and what cash hasn't been matched yet. The amount field is now a computed column, not a typed one — the “blank cell = ₹0” error class is gone by construction, not by someone remembering to double-check.
This sounds like you if
- You’ve looked for a SaaS or CRM that fits and it doesn’t exist for your specific workflow
- Customers email you for things a portal should handle
- An MVP got built once and never made it past a prototype
- Your team works around three different tools because none of them alone does the job
- You want something people actually use daily — not a feature announcement nobody opens
- The “custom” system you have now is a spreadsheet held together by someone’s memory
What you get
- Fixed-price proposal for a first shippable version
- UI/UX and engineering from the same team
- Testing on your real data and edge cases before launch
- Full source and infrastructure access on delivery
- A support window after launch — optional ongoing feature work
- A clear call on what’s needed for launch vs what can wait

Questions about custom software
Yes, when it makes sense. In scoping we’ll say if extending what exists is faster than a rebuild — we don’t default to a rewrite for our convenience.
We can set it up and hand over full access, or work inside what you already run. Either way, you’re not dependent on us to keep the lights on.
Expected. We ship a first version fast, then scope additions as a follow-on with their own price and timeline — instead of guessing everything up front.
Supabase Auth handles the session — email/password, magic link, or SSO if you need it — and Postgres Row Level Security enforces that a logged-in user’s queries only ever return the rows their role should see. We map that identity to the same customer or employee ID your CRM or HR system already uses, not a second disconnected identity system.
Default is Svelte + Supabase. Svelte compiles away the framework, so there’s no virtual-DOM runtime shipped to the browser — first load stays fast even on a tool people didn’t already have open. Supabase gives us Postgres, Auth, and file storage with Row Level Security built in, which covers most of what a custom system’s backend needs on day one. If your team already has a stack, we build against that instead — you maintain it, not us.
Internal tools is one job, one screen, fast and cheap. Custom software is the build when the requirement doesn’t reduce to a single screen: multiple roles, multiple surfaces, or customers and your own team on the same system.
Yes — a fixed-price design-only engagement if your team can implement from a clear handoff: Figma files, a documented type scale and color system, and contrast checked to WCAG 2.1 AA — not a vibe board someone has to reinterpret.
Yes. Source, deploy access, and docs at handoff — same ownership model as our workflow and skill builds.
