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

Wrencher is a desktop application designed for Windows, catering specifically to sole traders and small trade businesses. This software integrates essential functions such as client management, quoting, job scheduling, alerts, invoicing, and mileage tracking into a single platform. Users have the ability to create detailed quotes with various options, easily transform those quotes into invoices, and manage their tasks using a weekly calendar. The target audience for Wrencher includes electricians, plumbers, HVAC technicians, builders, landscapers, and a variety of other tradespeople. The application operates directly on the user's computer following license activation, eliminating the need for accounts, logins, or cloud services. It is tailored for tradespeople who prefer keeping their data on local storage while handling quotes, scheduled tasks, client information, invoices, and mileage through a straightforward desktop interface. Wrencher is available exclusively for Windows users, offering a 30-day full-feature trial alongside licensing options priced at $99 annually or a one-time fee of $299 for lifetime access. Its primary focus is on daily quoting and job management rather than being an extensive field-service solution. Additionally, Wrencher's user-friendly design makes it an ideal choice for tradespeople looking to streamline their operations efficiently.
