Description

Coretool is an online invoicing platform designed specifically for freelancers, sole traders, tradespeople, small service businesses, and other enterprises in Germany. With this application, users can generate and oversee quotes and invoices, including compliance with XRechnung and ZUGFeRD e-invoicing standards, manage customer relationships, issue payment reminders, and schedule appointments. The software integrates GiroCode QR codes, facilitates digital signatures for quotes, and enables e-invoice document validation through its REST API. By utilizing API-based workflows, users can link Coretool with automation platforms like Make, Zapier, and n8n, though access to certain specialized modules may require approval. Additionally, it allows users to incorporate calendar feeds into Google, Apple, or Outlook calendars. An optional Kalkulations-Assistent feature aids in estimating projects, calculating materials and labor, and producing quotes. Coretool operates entirely within a web browser, eliminating the need for any local software installation. The free plan permits the issuance of three invoices each month, while the Solo plan is available for €9 per month plus VAT and offers the flexibility of monthly cancellation. Furthermore, the intuitive interface makes it easy for users to navigate through the various functionalities and enhance their invoicing experience.

Description

TwoBucket is beginner-friendly mobile detailing software, built for detailers who wash, detail and coat cars at the customer's driveway, often on their own. You can have a booking page live in a few minutes. Customers pick services and add-ons, mark the car's condition and add photos, without an app or account. You reply with an estimate or a quote they approve online, and the invoice gets a Pay button for card, Apple Pay and Google Pay through your own Stripe or Square account, with deposits and no TwoBucket fee. Visits sync to Google Calendar or iCloud. "On my way" texts, a job timer, before and after photos, review requests and rebooking emails are built in, along with earnings by week, month or year. Use it on the web or in the iPhone and Android apps, in 15 languages, or connect ChatGPT, Claude, Gemini, Grok or Muse. Everything is in one plan for $20 a month, with a 7-day free trial and no card needed.
