SaaS Product Development
SaaS products built right: multi-tenancy, subscription billing, and auth from day one.
A 0-to-1 SaaS build is not a bigger version of a marketing site or an internal tool. From the day a second customer signs up, the product has to hold state for multiple tenants at once, take money on a recurring schedule, and keep working correctly when a background job fails halfway through. Most of the technical debt we get called in to fix later didn’t come from bad code on its own — it came from a tenancy model that quietly assumed one customer, a billing integration that only handled the happy path, or an MVP that kept growing until there was no MVP left to actually ship.
We treat the product and the infrastructure underneath it as one decision, because in a SaaS product they are one decision. Whether tenants share a database with row-level security or get their own schema changes how every query in the app gets written. Whether usage is metered in real time or reconciled nightly changes what the background workers look like. Whether enterprise SSO is a day-one requirement or a later add-on changes the shape of the auth layer from the start. We would rather make these calls deliberately, in a scoping sprint, than have a customer’s support ticket make them for us six months in.
What we build
Most 0-to-1 engagements cover the same core pieces. Tenant isolation enforced at the database layer, not just checked in application code, so a bug in one API route can’t return another tenant’s data. Authentication and role-based access — usually through an identity provider like Clerk or Auth0 rather than hand-rolled session logic, especially if SSO or SAML is on the roadmap for an enterprise tier. Subscription billing on Stripe Billing: plan tiers, seat- or usage-based pricing, proration when someone changes plans mid-cycle, dunning when a card fails, and webhook handlers that are genuinely idempotent, because Stripe will send that payment_succeeded event more than once. Background workers on Redis and BullMQ, or your existing queue if you’re already on Laravel, for anything that shouldn’t block a request: emails, exports, report generation, retrying a failed webhook. And usage metering where the pricing model calls for it — ingesting events, aggregating them without double-counting, and showing the customer their usage before Stripe bills them, not after.
How we work
We default to a plain stack: Next.js on the frontend, Node/Express or Laravel on the backend depending on what your team already knows, Postgres as the system of record, Redis for jobs and caching. Not because it’s the only stack that works, but because when the goal is a first paying customer, the stack we can move fastest and safest in beats the one that’s more interesting to build. We’ll reach for something else when the product actually calls for it — database-per-tenant isolation for a client whose contracts require it, for instance — but we don’t start there by default, since operating and migrating hundreds of separate tenant databases is a real ongoing cost most products never need to carry.
The build runs in weekly increments with a working demo at the end of each one, not a single reveal at the end of month three. Scope control is part of the job: if a feature won’t affect whether an early customer pays, we’ll say so and suggest cutting it, even if it’s the feature you’re most excited about. We’ve done that on past builds and watched the cut feature turn out not to matter, which is more or less the point of an MVP. We run standups and keep same-day answers the norm, not the exception, so decisions don’t stall waiting on a reply.
This is the right engagement if you’ve already validated that people want the thing and now need it built properly — tenant isolation, billing, and auth that won’t need a rewrite the first time the customer count climbs. It’s not the right fit if you’re still testing whether the idea is worth building at all; that conversation is worth having with actual prospective customers first, and we’ll tell you plainly if that’s where things stand. It’s also more infrastructure than a single-tenant internal tool or a simple content site needs — those are better served by a smaller build than the full multi-tenant treatment.
What this is meant to achieve
The measures we hold the work to, agreed with you before the build starts.
A live multi-tenant product that can onboard a new paying customer without a manual database step
Subscription billing that handles upgrades, downgrades, failed payments, and cancellations without a support ticket
An architecture that doesn't need a rewrite the next time tenant count grows by an order of magnitude
An architecture decision record and codebase your next engineering hire can pick up without a handover call
A shipped MVP scoped tightly enough that you know what you're actually testing with real customers
Questions people ask before signing
Straight answers on pricing, code ownership, timelines and what happens after launch.
Yes — that’s a large share of what we do. We start with a short code and architecture review before quoting anything, so we’re honest about what’s reusable and what actually needs to be rebuilt, instead of defaulting to a rewrite.
Both. A full 0-to-1 build is the more common engagement, but we also get brought in for one piece — retrofitting Stripe Billing onto a product that launched with manual invoicing, for example, or fixing a tenancy model that’s starting to leak data between accounts.
Mostly by compliance requirements and tenant count, not by default preference. A shared database with row-level security is simpler to run and migrate, and covers most B2B products comfortably. We move to schema or database isolation when a contract requires it or a tenant’s data volume genuinely justifies the extra operational overhead, not before.
Yes, and it’s often the better setup. We’ll take ownership of a defined piece — billing, the queue infrastructure, the tenancy layer — and work against your existing repo and conventions, rather than running a separate codebase you have to merge back in later.
Most clients move to a support retainer for bug fixes, monitoring, and small feature work once the product is live. We size that separately once we know what launch actually looks like, since it depends on how much ongoing feature work you’re planning.
Sometimes, for the genuinely generic parts — an auth screen, a billing settings page. We’re less convinced by boilerplates for the tenancy model and data architecture, because that part is specific to your product, and a starter kit’s opinions about it are rarely the right ones for what you’re building.
