Why teams call us

Three reasons a SaaS team calls us.

Most SaaS engagements start from one of these three problems. Recognise yours and the rest of this page gets more useful.

  • The product only works because it was built for one customer

    Account IDs hardcoded into queries, no real tenant isolation, and every new customer needs a code change before they can use it.

    We rebuild the data model so a new tenant is a signup, not a deploy.

  • Billing runs on invoices and a spreadsheet

    Plan changes, upgrades and cancellations get typed in by hand, and nobody is confident the number on the invoice matches what the customer actually used.

    Subscriptions, metering and invoicing wired to your billing provider, not to memory.

  • Support runs raw database queries to answer a ticket

    There is no admin panel, so answering "what plan is this customer on" means someone opening a database console.

    An internal admin tool your team can actually use, with the right access.

What you actually get

What a SaaS build actually hands you.

Six artefacts a SaaS engagement produces, not a slide about frameworks.

  1. A data model with tenants built in

    Multi-tenant from the schema up: every table scoped to an account, so a new customer is a row, not a migration. It is the same pattern behind the products we run ourselves.

  2. Working billing in the first release

    Plans, upgrades, downgrades and cancellations wired to Stripe or your billing provider, with proration and failed payments handled up front.

  3. An admin panel your team can use on day one

    A real internal tool for support and operations: search accounts, adjust plans, see usage, without a database console.

  4. Code and infrastructure in your accounts from day one

    Your GitHub, your cloud account and your billing provider account, with commit and admin access from the first sprint.

  5. Tests on billing and account access

    Automated coverage on the paths where a bug costs you a customer or a refund: billing, plan limits and access control.

  6. Documentation and a handover

    A data model diagram, a runbook for common admin tasks, and a walkthrough so your team can operate the product without us.

What it costs

Three ways to start, priced honestly.

Ranges, not single numbers, because the real figure depends on integrations and migration scope. You get the exact number in writing after one call.

  • Launch

    One core journey, production-ready.

How it runs

From first call to running software in four moves.

The same process on every engagement, whichever package you start from.

  1. Scoping call

    A working call about the outcome and the constraints. Not a pitch. If you are still pre-revenue, we will point you at the startup MVP programme instead.

    Day 1–3

  2. Written scope & price

    Architecture options, timeline and a price range you can take to your board.

    Within 48 hours

  3. Prototype & build

    Clickable prototype, then working software in fortnightly sprints.

    Week 1 onward

  4. Launch & operate

    Deployment to your cloud, monitoring in place, then the next slice.

    Launch week

Proof

SaaS product development engagements we scoped, built and still support.

Different sectors, same process, and in each case the client owns the code.

How we work

A product engineering culture built on ownership and clarity.

The habits that decide whether software still works in year three. Here is the honest comparison: what most outsourced engagements look like, and what changes when you work with us.

How an engagement with QalbIT compares
The questionThe usual answerAt QalbIT
Who scopes itA salesperson, then a handover docThe founder and the engineer who will build it
Who writes the codeWhoever is on the bench that monthNamed senior engineers, in our office, no subcontractors
What you see weeklyA status deck and a percentageA working demo and the board it came from
When something breaksA ticket queue and an account managerThe engineer who wrote it, in your timezone overlap
If you want to leaveA migration project and a licence conversationThirty days notice · repos and IP were always yours

  • Principle 01

    Ownership over ticket-taking

    Engineers who ask why before they ask which framework. Scope questions come back before code goes out.

  • Principle 02

    Written over remembered

    Scope, estimates and architecture decisions are written down with the trade-off stated. Nobody relies on what was said on a call.

  • Principle 03

    Small over staffed

    Senior pods that hold the whole system in their heads beat large mixed teams that need a coordinator to function.

Engagement models

Flexible engagement models.

Choose how you want to work with us based on where your product is today. We help you validate, ship and then scale without forcing you into a one-size-fits-all model, and how we price projects follows the model you pick.

  • Best for defined scope

    Fixed-scope projects

    Best when requirements are clear and we can estimate precisely.

    • Clearly defined scope, milestones and deliverables.
    • Predictable budget with upfront estimates.
    • Ideal for MVPs and discrete feature releases.

    Works well with good documentation or a short discovery

  • Most chosen

    Dedicated product squad

    A cross-functional team that behaves like your in-house product team.

    • Stable team for long-term ownership and roadmaps.
    • Capacity planned monthly with clear velocity.
    • Founder involvement on architecture and key decisions.

    When software is core to your business

  • Best for ongoing work

    Time & material / Agile

    Ideal for ongoing iterations, R&D and integrations.

    • Pay for actual engineering and design time used.
    • Flexible backlog and scope, prioritised every sprint.
    • Perfect for experiments and proof-of-concepts.

    When agility matters more than fixed scope

What protects you

Five commitments that make the first engagement low risk.

The objections worth raising before you sign anything, answered up front rather than buried in a contract.

  • Free written scope

    Scope, timeline and price range within 48 hours, yours to keep whether or not you hire us.

  • IP and repos yours, day one

    Code, repositories and cloud accounts in your name under NDA, with commit access from week one.

  • Changes quoted in writing

    Added scope is priced and approved before it is built. The number never moves quietly.

  • Replacement guarantee

    If an engineer is not the right fit we replace them at no recruitment cost, with handover before they leave.

  • 30 days notice

    Monthly engagements end or scale down with 30 days notice. No annual lock-in.

Frequently asked questions

Cost, timelines, tenants, billing and what happens after your first paying customer.

Ask us directly →
Actually isolated. We build multi-tenant from the schema up, with every table scoped to an account, so a new customer signing up is a row in the database, not a code change or a deploy.
Yes. Plans, upgrades, downgrades and cancellations get wired to Stripe or your billing provider in the first release, with proration and failed payments handled up front rather than patched in after a customer complains.
Launch, the smallest package, is built around one core journey in production, live in six to eight weeks, with a clickable prototype in week one so you can start selling before the build finishes. The written scope after your scoping call gives you the exact date.
No. The admin panel is part of the first release: your support team can search accounts, adjust plans and see usage from a real internal tool, not a database console.
Yes. Enterprise requirements like SSO get scoped as an addition on top of the multi-tenant architecture already in place, quoted in writing and approved before it is built, the same as any other change to scope.
Usually, yes. We start with a short audit that tells you honestly what the data model needs to become tenant-aware, what code can be adapted and what should be rewritten, and what each path costs.
That is what the Platform package is for: a named technical lead, performance and cost optimisation, monitoring and on-call, with the roadmap planned quarter by quarter instead of sprint by sprint. Most SaaS clients move onto it once billing and support tooling are proven and growth becomes the main problem.
