Why people consider alternatives to Invoice Koi
Invoice Koi is an invoicing app for Android phones, made for independent tradespeople and small trade businesses. Estimates are written on site from a price book of rates, signed on the phone and turned into invoices without retyping.

- Pricing at scale as usage or premium tiers add up.
- Missing integrations with the rest of your stack.
- Performance or scale limits as your needs grow.
- A specific feature gap you have hit in invoicing.
