Ledgerline

Ledgerline started as a single free invoicing/business-tools site for freelancers — no accounts, everything stored in localStorage. Since then it's grown into a small portfolio under Rahmanov.org:

• Rentline — tools for landlords/property managers

• - Sellerline — fee calculators for Etsy/Amazon/Shopify sellers

• - Agentline — commission split and closing cost tools for real estate agents

All four share the same architecture: static, no backend, no signup, free tier is unlimited use. Monetization is one $9/mo subscription that unlocks Pro features across all four products at once, rather than four separate paywalls.

Just shipped: each product now has its own distinct brand color instead of sharing one accent color site-wide, so they read as separate products rather than reskins of each other.

Current state, honestly: real traffic and revenue are both still close to zero. This post is part of actually trying to fix that instead of just building more tools into the void. If you've got a freelance invoice, a rental, an Etsy shop, or real estate listings, I'd genuinely appreciate you kicking the tires and telling me what's missing.
