ReverseBits

The SaaS engineering decisions that compound.

Multi-tenancy, billing, admin tooling, and compliance - engineered in the order that prevents the rewrite. Integrations and data pipelines threaded through, not bolted on at month six.

How SaaS engagements begin

Four situations we recognize by the second sentence.

Most SaaS engagements with us start in one of four shapes. If you see yourself below, we have a strong opinion about how the next twelve weeks go.

01

"We shipped single-tenant to validate. Now we're stuck."

50-500 customers, a refactor quietly delayed for 18 months. Our first deliverable is a three-year cost projection across the tenancy options. Sometimes the math says ship now; sometimes hold another year. We've seen builds where row-level security would have held for five years if the original team had added a tenant_id column at week one.

Typically ships

  • RLS migration
  • Tenant onboarding
  • Admin rework
  • Zero-downtime cutover

02

"Stripe Subscriptions can't handle our pricing anymore."

You've outgrown plan-per-customer. Usage-based pricing, hybrid plans, partner revenue share, or mid-cycle entitlement changes are forcing engineering work that should be billing configuration. We migrate from Stripe Subscriptions to Stripe Billing, or layer thin custom logic where Billing genuinely won't reach.

Typically ships

  • Pricing model audit
  • Stripe Billing migration
  • Custom entitlement engine
  • Finance handoff docs

03

"The admin dashboard is slowing the company down."

Ops files engineering tickets for things that should be self-serve. The admin tooling was built first and maintained last. We treat it as a real product, with the same engineering bar as the customer-facing app. Ops touches admin tools hundreds of times per day; customers touch your product once a week.

Typically ships

  • Admin rebuild
  • Audit log
  • Bulk operations
  • Role-based views

04

"We need SOC2 prep without slowing the build."

You're closing enterprise contracts that require SOC2 Type I evidence. Retrofitting compliance post-launch typically costs five times what packaging it during the build costs. SOC2 evidence threads through engineering from week one: encrypted secrets, access reviews, audit logs, control documentation as artifacts rather than policies.

Typically ships

  • SOC2 evidence pack
  • Access policy
  • Audit log instrumentation
  • Auditor coordination

Our process

Every layer of the build, shown end to end.

Six stages from scoping to scale. Click through to see what gets produced at each stage and the artifacts you walk away with.

Scope the problem, lock the architecture decisions.

Feature list mapped against the architecture tradeoffs that matter: tenancy model, billing approach, auth provider, integrations surface. End of week one: a decision document for each, an architecture sketch, and cost implications.

Frequently Asked Questions

The questions founders ask before choosing a tenancy model, billing architecture, and launch plan.

Ask a Question ->

Multi-tenant suits most B2B SaaS in 2026: lower per-customer cost, simpler ops, faster feature rollout. Single-tenant fits enterprise contracts requiring strict data isolation, regulated industries with residency rules, or buyers contractually demanding dedicated infrastructure. Hybrid works for SaaS moving from B2B-SMB to upmarket.
