The micro-saas stack

Six instruments, calibrated.

UK micro-SaaS — vertical-specific, low-volume, high-margin — onboarding, billing, retention without enterprise overhead.

01 · Niche onboarding

Vertical-specific sign-up, not generic SaaS-flow.

Sign-up tuned to the niche — accountancy practice, dental clinic, surveyor — pre-filled defaults, vertical-specific identity, the right activation milestone for the customer's actual job. Generic onboarding doesn't convert vertical buyers.

  • Vertical-aware sign-up flow
  • Stripe Checkout + Auth0
  • Niche-specific defaults
  • First-value event per vertical
02 · Per-customer cohort tracking

Low volume, high signal.

When you have 80 customers not 8,000, every account matters. Per-customer activity tracking, expansion signals, churn risk — surfaced in a queue you read on a Sunday afternoon, not a dashboard you ignore.

  • PostHog per-customer view
  • Activity & adoption tracking
  • Expansion-signal flagging
  • Per-account churn risk
03 · Billing automation

Stripe Billing for the long-tail customer.

Annual contracts, custom pricing, mid-term plan changes, Xero reconciliation. The billing system that handles the awkward edge cases without a Sunday on the laptop.

  • Stripe Billing + custom prices
  • Annual contract handling
  • Xero reconciliation via Synder
  • Dunning & retry automation
04 · Vertical-specific integrations

The integrations the niche actually uses.

The CRM, accounting tool, or industry platform every customer in the niche already runs. Built once, owned by you, replacing the Zapier mess that breaks every quarter. Stickier than features.

  • Native API integrations
  • Webhook-based sync
  • OAuth-secured connectors
  • Integration health monitoring
05 · Customer success

High-touch without a CSM team.

Plain inbox + product context + low-volume cadence — the founder's customer-success motion at scale. Quarterly business reviews on autopilot, save-plays per account, expansion conversations triggered by usage.

  • Plain inbox + product context
  • Save-play queue routing
  • Quarterly review automation
  • Expansion-trigger workflows
06 · BrainBase

Vertical knowledge + customer playbooks.

Niche regulation, customer FAQs, integration runbooks, sales scripts — searchable from the IDE, the support inbox, the sales call. The vertical brain that beats the generic competitor.

  • Vertical regulation notes
  • Customer-FAQ archive
  • Integration runbooks
  • AI-assisted retrieval
Sample engagement

The vertical micro-SaaS that doubled annual contracts.

Two founders. 80 paying accountancy firms. Stripe + Xero + a Notion CRM the founder updated weekly.

A UK micro-SaaS for accountancy practices ran on Stripe for billing and Notion for everything else. Three-week build: Stripe Billing for annual contracts, per-customer activity tracking via PostHog, vertical-aware Plain inbox, save-play queue. Six months in: annual contract take-up doubled, churn dropped two points, founder reclaimed Sundays.

How we measure: Annual contract conversion measured at renewal across 80 accounts pre-build vs 92 accounts post-build; churn = quarterly logo churn rate, rolling four quarters.
