1.Summary
Acme is building a solid vertical SaaS, but the prototype puts most of its complexity in the field-service features while the operating layer — tenant isolation, roles, billing, workflow reliability and audit — is still thin. That is the part that will block the first serious customer and consume the next three to six months if built from scratch. Our recommendation is to stand that layer up on MergeMind Platform and keep Acme's engineering focused on the field-service product itself.
2.Recommended platform modules
| What Acme needs | MergeMind Platform module |
|---|---|
| Multiple customer companies (tenants) with isolated data | Tenancy — lifecycle, isolation & policies |
| Company admins, dispatchers and field techs with different access | Identity + RBAC/ABAC |
| Per-seat & usage subscription billing | Billing — subscriptions, invoices & ledger |
| Job/dispatch state machine with reliable transitions | Workflows — orchestrated sagas |
| Who-changed-what history for compliance | Events & Audit — outbox + immutable log |
| An operator console to run and support customers | Admin operations — portals & feature flags |
3.Build-risk assessment
Tenant-level permissions
Field techs must never see another company’s jobs. A shared table with a tenant_id filter will leak data under the first edge case — this needs enforced isolation, not convention.
Job workflow orchestration
Dispatch → en-route → on-site → complete → invoiced must survive retries and partial failures. Hand-rolled status fields drift; a saga with recovery keeps it consistent.
Billing correctness
Mixing per-seat and usage billing by hand invites revenue leakage. A double-entry ledger makes every charge auditable.
Storefront / marketing
Low risk — standard, and not where your engineering time should go.
4.3-step execution plan
01
Foundation sprint (weeks 1–3)
Stand up identity, tenancy, RBAC and billing on MergeMind Platform
Model companies, users and roles; enforce isolation at the data layer
Operator admin console for onboarding and support
02
Core product (weeks 3–7)
Job/dispatch workflow as an orchestrated saga with recovery
Field-tech and dispatcher views on the platform SDK
Audit log + events wired for compliance from day one
03
Launch & harden (weeks 7–10)
Usage + subscription billing live with the ledger
Observability (tracing, metrics, logs) and deploy pipeline
Pilot-customer go-live support and handover
5.Indicative timeline & cost
6–10 weeks
Foundation in ~3 weeks; first pilot-ready product in 6–10.
$12k–20k
Range for a done-with-you MVP on the platform; confirmed after scope. Platform plan billed separately.
6.Recommended next step
Start with a SaaS MVP Sprint: stand up the foundation, ship the job workflow, and get Acme to a pilot-ready product in weeks — then scale on the same platform without a rewrite.
