Hiveage is a cloud-based invoicing, billing, and online-payments platform built for freelancers, agencies, and small service businesses.
Vertical: Financial Services. Sub-vertical: SMB/freelancer online invoicing and billing. Creating and sending branded invoices and estimates with online payment links. Recurring/subscription invoicing for retainer clients. Time, expense, and mileage tracking that flows onto invoices.
Low-to-moderate. Hiveage is well-known within the freelancer/indie-consultant niche as a lightweight FreshBooks/Wave alternative, but it is a long way behind the top tier of SMB invoicing/accounting brands.
Client/contact master data (names, emails, addresses, payment terms). Invoices, line items, taxes, discounts, statuses, hash keys. Estimates/quotes and conversion records. Recurring billing schedules and next-run timestamps.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
