In their own words
Billbooks
Billbooks is an online billing application for freelancers and small businesses, covering invoices, quotes, scheduling, expenses, and reports. It supports recurring invoices, online payments, payment reminders, multi-currency invoicing, digital signatures, and a client portal. Every paid plan includes recurring invoices, automatic reminders, multi-currency support, digital signatures, and reports. Payment gateway options include PayPal, Stripe, Braintree, and Authorize.Net. The public REST API covers invoices, estimates, clients, items, expenses, expense categories, and taxes; API keys are not limited by plan. The API has no webhooks and is limited to 300 requests per five minutes per resource. Xero, QuickBooks Online, and Zapier connectors are available on Professional; Xero connects directly, while the other listed apps connect through Zapier. Billbooks offers iOS and Android apps that sync with the web app, alongside web, macOS, Windows, and API access. Pricing starts with Basic at $7.95 a month. A 30-day trial costs nothing and includes one user, five clients, 100 items, three projects, and five invoices and estimates. Billbooks says it encrypts data in transit and backs it up daily off-server to Amazon S3, with a seven-day retention window.
