Tool 1: The unified ops dashboard
Pulls live data from Stripe, HubSpot, Linear and your DB into one screen your team actually opens. Replaces a Notion page that's always out of date and three browser tabs per person. Typical build: 4–7 days, $4–6k. Replaces $8–12k/year in SaaS.
Tool 2: The customer admin panel
Lets support staff find a user, see their data, refund a payment and resend an email without engineering involvement. Replaces 'can you run this query for me?' Slack messages forever. Typical build: 3–5 days, $3–4k.
Tool 3: The bulk-action tool
Whatever the one thing is your team does 500 times a month by hand — approving, tagging, reassigning. A custom UI for the bulk action saves 10+ hours a week. Typical build: 2–4 days, $2–3k. Pays back in a month.
Tool 4: The internal AI assistant
Searches your company's docs, tickets and Slack history with natural language. Replaces three SaaS tools that each search one silo. Typical build: 5–8 days, $5–7k. Saves every employee 30+ minutes a week.
Why custom usually wins here
Internal tools have one stakeholder (you), no marketing, no SEO, no design polish needed. The whole cost is the build. Off-the-shelf alternatives charge per seat forever — and never quite fit your workflow.
