When does off-the-shelf SaaS win?
When the workflow is standard (CRM, helpdesk, accounting), the per-seat price is under $30/month, and you have fewer than 50 seats. Retool, Airtable, HubSpot — pay the money, move on.
When does building custom win?
When the workflow is your competitive edge, when seat counts push the SaaS bill past $2k/month, or when three different SaaS products are being held together with Zapier and prayer. At that point custom pays for itself inside a year.
The 3x rule
If the SaaS subscription will cost more than 3x what a custom build would cost over three years, build it. We've replaced $18k/year SaaS stacks with $8k one-off builds — the maths is rarely close.
What people forget to count
Onboarding new staff onto five different tools. Data trapped in vendor silos. Integration fees. The 'enterprise tier' upcharge when you cross a seat threshold. The real SaaS cost is usually 2–3x the sticker price.
What we recommend most often
A custom thin layer over the SaaS you already use — pulling data from HubSpot, Stripe and Linear into one workflow your team actually opens. Cheap to build, immediate to feel.
