Where Spreadsheets Wins
Let's be fair:
Free (if you don't count your time)
Spreadsheets cost nothing. If you're comfortable building and maintaining them, the only investment is your time.
Total customization
You can build literally anything. Custom reports, unique calculations, bespoke workflows.
Works offline
No internet? No problem. Your spreadsheet is always available.
You already know them
If you're proficient in Excel or Sheets, there's no learning curve for the tool itself.
Where Erin Wins
No formula building
PAYE brackets, VAT calculations, CIT tiers — all built in. You'll never write =IF(AND(... again.
Nigerian tax law updates
When FIRS changes rates or thresholds, we update Erin. Your spreadsheet stays stuck in the past.
Safe to Spend
A concept spreadsheets can't replicate easily. Know what you can actually spend — automatically.
Professional invoices
Generate branded invoices in seconds. Track payments. Send reminders. No separate templates.
Mobile-first
Built for your phone. Check your finances while waiting in traffic. Spreadsheets on mobile are painful.
No maintenance
Spreadsheets break. Formulas get overwritten. Links fail. Erin just works.
