Frequently asked questions
Hiveage scores C on the API Report Card. Hiveage has a public JSON REST API covering invoices, recurring billing, estimates, payments, expenses, and time tracking. It is enabled only on the paid Plus plan, and auth is HTTP Basic with a long-lived per-user API key against a per-account subdomain base URL.
Hiveage has an official API, but teams routinely hit its limits: gated access, partial coverage, or paid tiers. Most end up supplementing it with exports or an unofficial API layer like Supergood. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
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.
Hiveage's underlying product lineage (CurdBee → Hiveage) dates to 2008, making the codebase ~17 years old; the Hiveage rebrand/rebuild shipped in 2014, so the current public product is ~12 years old.
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.
