The problemYour prototype worked in the demo. Then real, paying users logged in.
In shortSaaS development from Pixel & Oak is for founders whose idea or prototype has to survive paying users. We build the parts that usually break, such as login, Stripe billing including failed payments, permissions and per-customer data isolation, in Next.js and Postgres inside your own accounts. Fixed price per phase, from $12,000, typically 8–16 weeks.
Most SaaS products do not fail on the clever feature. They fail on the boring parts: the login that stops working after launch, the failed payment that never removes access, the permission rule that lets one customer see another's data. If your app was built with Lovable, Bolt, Replit or Bubble, or left half-finished by a freelancer, those are usually the parts that break first.
As a SaaS development company, we build in phases with a fixed price on each, so you can stop after any of them with something that runs. Phase one is the smallest thing a real customer would pay for. Your GitHub, hosting, Stripe and domain are yours from day one. Our AI agents write and test the code, and Haider Ali, the founder, reviews and signs off every release.

These are the problems founders bring to us, usually a few weeks after launch.
Login stops working, the database times out, a webhook fails without a sound. Each incident costs days while paying users hit errors, and you cannot tell whether the next fix will break something else.
What we doWe harden the app you have or move it to a boring stack: an established auth provider, retried and monitored webhooks, indexed queries, and error alerts that reach you before a customer complaint does.
Monthly credits go on bug fixes instead of features. You go in circles, and the launch date keeps slipping.
What we doWe move the product into a real codebase in your own repository, with tests on login, billing and permissions, so a change in one place cannot quietly break another. Fixed price per phase, not open-ended credit burn.
In many prototypes, yes. Researchers have found AI-built apps whose missing or inverted access rules let anyone read other users' records (CVE-2025-48757). One leak means legal exposure and lost trust.
What we doWe design the permission model and wall off each customer's data, then test it from the attacker's side: row-level security on every table, no service keys in the browser. A code-level review, not a certified pentest.
A silent revenue leak. The webhook reports success, nothing in the dashboard looks wrong, and customers keep using what they stopped paying for.
What we doWe build billing for the failure paths: failed payments, retries, cancellations, refunds and plan changes, with webhook handlers that update access, plus a check that compares Stripe against your database.
You cannot fix bugs or ship the last 10%, calls go unanswered, and a second developer bills you just to untangle access and work out what was built.
What we doEverything sits in your accounts from day one: GitHub, hosting, Stripe and domain. For an abandoned codebase we start with a short paid audit that says honestly whether finishing or restarting is cheaper.
The app is slowest exactly when growth arrives. A plan upgrade does not always fix it, and usage-based bills are hard to predict.
What we doWhen a specific, revenue-linked limit is hit, we move the core product to Next.js and Postgres. Many Bubble apps can be tuned in place instead, and if yours can, we will say so.
We would rather tell you now than take the project and disappoint you.
| Starts from | $12,000 per phase, fixed price |
|---|---|
| First version | Typically $12,000–$35,000 |
| Typical timeline | 8–16 weeks; a tight first version is often 8–12 |
| Best for | B2B founders with a validated idea, or a prototype breaking under real users |
| Not for | Unvalidated ideas, equity-only deals, or certified compliance audits |
| What you own | GitHub repository, hosting, Stripe account and domain, from day one |
| Built with | Next.js, TypeScript, Postgres and an established auth provider |
| How pricing works | Fixed price per phase; you only commit to the next step |
Worth knowing: The most expensive decision in a SaaS build is starting with too much. Every feature added before the first paying customer is a feature you may be maintaining for nothing. A narrow first version that ships is worth more than a complete one that is still three months away.
Sign-up, sign-in, password reset, sessions and roles, using an established provider rather than hand-rolled auth, because this is a bad place to be inventive.
Subscriptions, trials, upgrades, downgrades, failed payments and refunds, with the webhooks that keep your database honest about who is actually paying.
The screens your customers live in, designed for the job rather than decorated.
A multi-tenant database design where one customer can never read another's records, and no decisions that trap you at a thousand users.
Scheduled backups and error alerts, so you hear about a problem before your customers do.
You will need to look things up, refund someone and fix a broken account. Building that later always costs more.
Documented, in your repository and your accounts, so another developer can pick it up without archaeology.
A 22-second look at the work: per-customer data isolation, authentication, Stripe billing with its failure paths, and monitoring with alerts. From $12,000, 8–16 weeks.
Worked in the demo. Then paying users logged in. Logins fail, webhooks fail silently. Customers can see each other’s data. Payment failed, access still open. There’s a better way. SaaS development that makes prototypes production-ready. Authentication done properly. Stripe billing, failure paths included. Per-customer data isolation. From $12,000 · 8–16 weeks · fixed quote.

These are the pieces SaaS development has to get right before the first paying customer. Each line is what goes wrong without it.
Our security checks are a code-level review from the attacker's side. They are not a certified penetration test, SOC 2 or PCI audit.
A focused first version usually costs $12,000–$35,000, quoted as a fixed price per phase. The range is wide because "SaaS" covers everything from a single-purpose tool to a multi-tenant platform. These are the things that move it:
| Cost driver | Toward $12,000 | Toward $35,000 |
|---|---|---|
| Workflows | One core workflow done properly | Several connected workflows |
| Users and roles | One type of user | Teams, roles and approvals |
| Data isolation | One customer per account | Many organizations in one system, each walled off |
| Billing | One plan, billed monthly | Trials, tiers, usage billing, upgrades and refunds |
| Integrations | None or one | Several third-party APIs and data imports |
| Existing code | A clean prototype we can build on | Code that needs repair before new work |
You see the whole roadmap but only commit to the next phase.
We take over apps built with Lovable, Bolt, Replit or Cursor, no-code apps on Bubble, and code a freelancer left behind. The order is always the same:
If you only want a second opinion on existing code, a code audit is the smaller first step. If the app runs on Bubble and mostly works, tuning it in place may be enough.
Deliberately mainstream choices. You should be able to hand this to any competent developer later without them needing to learn something exotic first.

A focused first version typically runs $12,000–$35,000. The range is wide because "SaaS" covers everything from a single-purpose tool to a multi-tenant platform with teams, roles and usage billing. We quote a fixed price per phase, so you never commit the whole budget on day one, and you can stop after any phase with something that runs.
Typically 8–16 weeks for a first version. A tight one, built around one workflow done properly, is often 8–12 weeks. The fastest route is a narrow scope, not more people. You get a staging link from week one and a written update every week, so you can use the product while it grows.
Often, yes. We start with a short paid audit of the code, accounts and data rules, then tell you honestly whether to fix what you have or rebuild the core. Sometimes the honest answer is restart, and you deserve to hear that before spending more. Either way, the result lives in your own repository.
Maybe not yet. The common gaps we look for are missing row-level security, service keys exposed in the browser, and permission checks done only on the screen rather than on the server. We review the code from the attacker's side and fix what we find. This is a code-level review, not a certified penetration test or compliance audit.
In a well-built app, their access changes once the retries you choose run out. In many prototypes nothing happens: the webhook reports success and the customer keeps using the product. We build handlers for failed payments, refunds, cancellations and plan changes, plus a check that compares Stripe with your database.
You do, from day one, not just at the end. The GitHub repository, hosting, Stripe account and domain are created in your name or transferred to you before we start. If we stopped working together tomorrow, another developer could pick up the documented code without asking us for anything.
Outsource when you have a validated problem, a clear first workflow and no technical cofounder to build it. Do not outsource before anyone has said they would pay; a landing page is cheaper. Hiring a studio for a fee also means you keep all of your equity.
Check five things before you sign. The code, hosting, Stripe and domain should be in your accounts from day one. You should get a staging link in the first week. The price should be fixed per phase. They should build for a fee, not equity. And they should be willing to tell you to fix rather than rebuild when that is cheaper.
No. We build for a fee, which keeps the relationship simple and means we are not steering your product toward our own upside. You keep full ownership of the company and the code, and there is no studio on your cap table when you raise money later.
