Nicolas,

Thank you for the time on Friday. It was a useful first conversation, and what follows is a proposal that reflects what you described — not a generic template.

We have deliberately structured the engagement into two workstreams that run in parallel. The first is the part Growzilla does every day: rebuilding your website on our platform, getting communications and CRM under one roof, and laying foundations you can grow into. That work is fixed in scope and ready to start immediately.

The second is the Inspection Reporting App. That is custom work — a multi-field form, an isotope picker, best-effort offline behaviour, and AI-assisted report drafting. The honest, professional way to price custom software is to scope it properly first, which is why we are recommending a brief paid discovery phase before quoting the build. You will know exactly what you are getting, and what it costs, before any development work begins.

Read what's useful. Push back on anything that doesn't fit. We are happy to adjust.

01 Our understanding of where Gamma Check is today

A twenty-year business carried on word of mouth — now ready for the systems to catch up.

From our conversation, the picture of where Gamma Check is today, and where you want it to be, looks like this. If we have any of this wrong, tell us — these are the facts the rest of the proposal is built on.

  • 01
    Gamma Check inspects approximately 15,000 radioactive isotopes across South Africa, serving roughly 90% of the country's mines. The business has grown for two decades almost entirely on word of mouth and is regulated by SAHPRA.
  • 02
    Inspections today rely on a 50-part paper questionnaire per isotope. Paperwork returns to the office, is captured manually by an admin, and a report is then written from that captured data — twice the work, twice the room for error.
  • 03
    A previous proposal for custom Windows-based software would have required ~R40,000 tablets per technician and was correctly declined. You want a mobile-first alternative that works on the phones your team already carries.
  • 04
    The existing Wix website (~20 pages) was a personal weekend build. Functional, but does not reflect the standing of the business — and is not built to support a future client portal or proper SEO foundations.
  • 05
    The five-person team includes a counsellor processing orders, a booker scheduling client visits, two regional technician teams, and a health & safety lead. Most platform usage day-to-day is internal: communications, CRM, and pipeline tracking.
  • 06
    Personal information (client ID copies, proof of address) is handled in office systems. Inspection-form data is technical in nature — you indicated POPIA exposure is therefore low at the form level. SAHPRA compliance remains a Gamma Check responsibility.
02 Proposed approach

Two workstreams. Running in parallel. Priced honestly.

One half is platform work we do every day, with a fixed scope and a price you already know. The other half is custom software, which deserves a proper discovery before anyone signs a build quote. Both start the same week.

Why this split matters. A digital inspection app sounds simple in concept, but the details determine whether it takes a week or two months: how the 50 fields branch, what conditional logic applies, how isotopes are identified, what offline behaviour is required, what the AI is meant to produce. Pricing that without scoping it would either over-charge you to cover risk, or under-quote it and end in friction. Discovery removes both.
03 Workstream 1 · Website & Growzilla platform

A site that reflects the standing of the business, with the platform underneath it.

Everything in this workstream is included for the Basic subscription price below. There is no separate website build fee — we treat your rebuild as part of standard onboarding.

Timeline

Week 1

Kick-off & setup

Content gathering, brand review, platform setup — CRM import, pipelines, inbox channels, booking calendars all configured to your team structure.

Weeks 2–3

Design & build

Website design, page-by-page build, and two structured review cycles. You see drafts early; we adjust before final.

Week 4

Train & go-live

Onboarding training sessions for your team — counsellor, booker, technicians, H&S — recorded so anyone who joins later can catch up.

Ongoing

Live & supported

Platform support is included. We check in at 30 / 60 / 90 days post go-live to make sure the team is getting value.

Total: approximately 3–4 weeks from kick-off, dependent on content and feedback turnaround from your side.

04 Workstream 2 · Inspection Reporting App

Replace the 50-part paper form. On the phones your team already carries.

This is the workstream that replaces the paper questionnaire with a mobile-friendly digital capture, with the option of AI-assisted draft report generation. It is custom software — and the right way to scope it is a short paid discovery phase before committing to a build price.

AI draft ready

Cs-137 inspection complete. Draft compliance report generated from the 50 captured fields.

Review draft
Mobile-first, not Windows-first

Built for the phones your technicians already carry. No more R40,000 tablets, no more paper returning to the office for re-capture.

Isotope picker

Each inspection is anchored to a specific isotope, serial number and last-seal date — pulled from your CRM, never re-typed in the field.

Best-effort offline

Captures continue underground or in poor signal. Forms cache locally and sync the moment connectivity returns. Final feasibility is a discovery question.

AI-assisted reporting

From 50 captured fields to a structured draft compliance report. You and Bernie review and sign. The AI's exact role is decided in discovery.

Concept illustration only. Field labels, form structure and the AI's exact responsibilities are mapped to your real 50-part questionnaire during discovery — not invented from a template.

What the discovery phase covers

  • Walk-through of your current 50-part inspection form. One completed example required so we can map every field, every dependency, and every conditional rule.
  • Technician workflow mapping end-to-end: dispatch → site arrival → isotope selection → inspection → submission → office review → report → client delivery.
  • Defining the AI's exact role. Are we generating a full draft, a structured technical summary, a checklist of recommendations, or simply pre-populating a template? Each is a different build.
  • Offline behaviour: feasibility test. In-platform form caching versus a dedicated progressive web app (PWA). Honest answers about what's realistically achievable on the Growzilla form builder versus where a second tool (e.g. Lovable, Bolt) may be required.
  • Review of one or two anonymised client reports so we understand the output target — not just the inputs.
  • Compliance scoping with you: what SAHPRA expects in terms of retention, audit trail, and data residency.
  • Architecture decision. In-platform Growzilla Form vs. AI App Build vs. dedicated PWA, with cost implications for each.
  • Risk register. The things that could go wrong, how likely, how we plan to handle them.

What you receive at the end of discovery

  • A detailed scope document covering every field, every flow, and every integration point.
  • A fixed-price build quote with a phased payment schedule. No range. No "approximately."
  • A realistic timeline with key milestones and review gates.
  • A go / no-go decision point. You are under no obligation to proceed with the build after discovery — the scope document is yours to keep.
To be clear: discovery is paid, scoped, and yours to keep. If you take the scope document to another build partner, that's allowed. We don't believe in tying clients into custom builds via lock-in — we believe in earning the build by doing the scoping work properly.

A note on plan tier

Pro plan, when you outgrow Basic

The Basic plan supports a single user profile and 1,000 contacts. Based on the five-person team structure you described, you will likely outgrow it once the counsellor, booker, and yourself all need separate logins for audit and attribution reasons. You can upgrade at any time — we recommend reviewing the tier 60–90 days after go-live once usage patterns are clearer.

06 Out of scope

What's deliberately not in here.

So there's no ambiguity later. The following are not included in this proposal. We can quote any of them as a separate engagement if and when you need them.

Native mobile app development. Our default is a mobile-responsive web interface, not iOS / Android binary builds.
Migration of historical inspection records, customer data, or accounting data from any legacy system.
Integration with Pastel or any other ERP / PO system, unless specified separately.
Ongoing SEO services. Technical foundations are included; campaigns, content production and link building are a separate engagement.
Paid advertising management. Google Ads, LinkedIn, programmatic — none of it is in here.
Certification of SAHPRA or POPIA compliance. See the regulatory note below — compliance ownership stays with the regulated entity, which is you.
07 Regulatory & compliance note

Plain language on data, hosting, and where responsibility sits.

What you need to confirm with SAHPRA before build

Gamma Check operates in a regulated industry. The Growzilla platform is hosted on cloud infrastructure outside South Africa (primarily United States). Based on our conversation, the data captured in inspection forms is technical in nature and does not include the personal information (ID copies, proof of address, etc.) that is handled separately in your office systems.

That said, regulatory responsibility for Gamma Check's data practices remains with Gamma Check. Before any inspection-app build begins, please confirm with your SAHPRA contact:

  • Cloud residency. That US-hosted cloud storage of inspection submissions is acceptable, or if an alternative arrangement is required.
  • Data retention. Minimum number of years inspection records must remain on file.
  • Audit & export expectations. The ability to extract inspection records on demand, in a documented format.

Growzilla will provide reasonable export and data portability tools, and our Terms & Conditions will include standard limitation-of-liability and indemnification provisions. We cannot, however, certify Gamma Check's compliance on your behalf. This is intentional — compliance ownership sits with the regulated entity, which is you.

08 Terms

Short, clear, and on the page.

Master Service Agreement

App development (Workstream 2) engagements are governed by a Growzilla Master Service Agreement (MSA), signed before any work commences.

Subscription billing

Subscription billed monthly in advance, in USD, by credit card. Covers the website and CRM platform.

No contract

Month-to-month. Cancel anytime — no lock-in, no termination fee.

Build phase invoicing

Build phase (Workstream 2) is invoiced per the payment schedule agreed at the end of the discovery phase. No surprise invoices.

09 What happens next

Four steps. Both workstreams running by week one.

01

You read this and decide.

Take whatever time you need. Push back on anything that doesn't fit. We'd rather adjust now than mid-build.

02

You sign off and we kick off.

Reply to the email this came with. We send the MSA, set up your account, and book the Week 1 kick-off call.

03

Both workstreams begin in parallel.

Website rebuild starts immediately. Discovery for the Inspection App is scheduled with you within the first 10 days.

04

You see the platform live by week four.

Website, inbox, CRM, calendar and pipelines all live. Inspection-app build quote on your desk shortly after.

· With thanks

Twenty years of expertise — finally with the systems to match.

You've built a business that ~90% of the country's mines trust. The next chapter isn't about replacing what works — it's about giving the people who carry the work the tools they deserve, and giving you visibility into the operation you've built.

When you're ready, we are.
