A senior software developer for SaaS companies

A SaaS company does not have one big sale to win; it has a hundred small moments that decide whether a trial converts, a team invites colleagues, and a renewal happens without a fight. When any of those moments is rough — a confusing signup, a billing surprise, a feature nobody discovers, a support answer that takes days — churn creeps up quietly, and the team only notices it in the monthly numbers.

The usual response is to add features, but the leak is rarely a missing feature. It is onboarding that leaves new users unsure what to do first, pricing and billing pages that create support tickets, product guidance that lives in docs nobody opens, and marketing that promises one thing while the product shows another. Fixing those moments is unglamorous, measurable work, and it compounds: every point of activation gained shows up in conversion and retention month after month.

A software developer builds and maintains the custom systems behind trial-to-paid conversion and customer retention: integrations, internal tools, and product features, written to last and documented so the next developer can pick them up. The engagement is senior-only and direct: you work with Omer, the scope is agreed before build, and the work is judged on what changes in trial-to-paid conversion and customer retention — not on hours logged or deliverables counted. Book a free discovery call and we will test the fit before any scope is agreed.

What you get

What this engagement covers for SaaS companies

  • Custom features and integrations — The capabilities your off-the-shelf tools do not cover, built against Chargebee and Pendo APIs.
  • Internal tools — Staff-facing tools for trial-to-paid conversion and customer retention that replace spreadsheets and manual workarounds.
  • API design and documentation — Clean, documented APIs, so future systems and partners can connect without reverse-engineering.
  • Legacy system rescue — Untangling and modernising the system nobody wants to touch, in safe, incremental steps.
  • Testing and code quality — Automated tests for critical paths, so changes stop breaking what already works.
  • Maintenance and handover — Documentation, monitoring, and a handover standard, so the software outlives any one developer.
Systems that SaaS companies actually run

Built for the stack you already pay for

SaaS teams typically run billing through Stripe Billing or Chargebee, product analytics through Segment, Mixpanel, or Pendo, customer success through Gainsight or Totango, and CRM and marketing through HubSpot or Salesforce, with Intercom or Zendesk on support. The product itself is usually tracked in Linear or a similar tool and designed in Figma. New work has to plug into that stack — events flowing to analytics, billing states reflected in the product, and support context available where customers actually ask for help.

Software work here is built on your existing stack — Chargebee, Pendo, your CRM, and your product platform — with version control, staging, and deployment discipline as standard, not as extras.

That discipline matters because the failure mode of outside help is usually a new tool nobody maintains. Work that lives inside Chargebee and your CRM survives the engagement; work that lives in a separate spreadsheet or dashboard dies the week the engagement ends. Every build here is therefore judged on whether your team can run it afterwards without the person who built it.

How it works

From kickoff to delivery for SaaS companies

  1. Map the system and the pain

    Review the current tools, code, and where trial-to-paid conversion and customer retention breaks today.

  2. Agree scope in slices

    Small, shippable pieces, each valuable on its own, instead of a big-bang rewrite.

  3. Build with tests

    Features delivered with tests on the critical paths and documentation as standard.

  4. Hand over properly

    Monitoring, docs, and a walkthrough, so your team is not dependent on one person.

Realistic outcomes

What success looks like, honestly

For a SaaS company, realistic outcomes are visible in product metrics: trial-to-paid conversion, time to first value, feature adoption, expansion, and churn. A good engagement moves one or two of those numbers and shows its working in your own analytics, rather than reporting activity such as pages shipped or posts published.

  • Outcome 1 — Custom capabilities your off-the-shelf tools cannot provide, built in shippable slices.
  • Outcome 2 — Internal tools that replace spreadsheets for trial-to-paid conversion and customer retention, with proper access control.
  • Outcome 3 — Code your next developer can understand, because tests and documentation are part of delivery.

No prices, guarantees, or client results are promised on this page, because the honest answer depends on your starting point: the state of your systems, the quality of your data, and how much of trial-to-paid conversion and customer retention is actually broken today. The discovery conversation exists to establish that baseline before any commitment is made.

Why Omer

Why hire Omer

  • Senior-only delivery: You work directly with Omer on your SaaS companies engagement, not through account managers or a handover chain.
  • Built on your stack: Chargebee, Pendo, and your CRM — not a parallel tool nobody maintains.
  • Measured on outcomes: Success is judged on trial-to-paid conversion and customer retention improving in your own numbers, not on activity delivered.
  • No lock-in theatre: Your systems, data, and documentation are handed over in full, so you are never held hostage by one engagement.
  • Direct communication: A core overlap window agreed before kickoff, with launches and incidents covered in your business day.
FAQ

Questions, answered

What does a software developer actually do for SaaS companies?
A software developer builds and maintains the custom systems behind trial-to-paid conversion and customer retention: integrations, internal tools, and product features, written to last and documented so the next developer can pick them up. In practice, that means help with trial-to-paid conversion and customer retention, working with founders and growth leads directly.
Will this work with Chargebee and Pendo?
Work is built around your existing stack. Chargebee and Pendo are treated as systems of record: new work reads from them where possible and writes back cleanly, rather than creating a parallel copy of your product usage and billing data. Where an integration is not available or not justified, the workflow is designed so staff are not left doing double entry.
What about regulation and compliance for SaaS companies?
SaaS work touches data protection, subscription billing practice, and the terms customers agree to, and the rules vary by jurisdiction. Nothing on this page is legal advice. Privacy wording, cancellation flows, and billing disclosures are checked against the rules that apply to your customers before anything ships.
Should we build custom software or buy a tool?
Buy when a tool covers the job well; build when the job is your differentiator or no tool fits how trial-to-paid conversion and customer retention actually works. The honest answer comes from mapping the job first, not from a preference for building.
How do we start?
With a discovery conversation about the work, the systems involved, and the outcome you want measured. Scope is agreed before any build starts — book a free discovery call, email omermuneer@gmail.com, or message on WhatsApp.
