About

Stacks is a hosted CRM and business workspace that brings customer records, sales pipelines, follow-up tasks, email campaigns, review requests, invoicing, appointment booking, support tickets and time tracking into one service. Shared customer records and activity history help solo operators, freelancers and small teams manage leads, sales, billing, bookings and customer support together. Users can maintain contacts and deals, create marketing emails, request feedback, issue estimates and invoices, publish availability, manage tickets, and track tasks and billable time. The core plan includes all seven modules for $0 per month with unlimited users and contacts. Free includes 50 one-time AI credits; an optional paid plan extends AI access. Businesses can connect their own Stripe account for payments and supported email providers for delivery. A REST API and MCP endpoint allow scoped access for software integrations.

About

servuno is a browser-based CRM and business operations platform for small and midsize service businesses, including trades, IT providers, agencies, driving schools and offices. It brings customer records, contacts, service agreements, recurring services, notes and customer histories into one workspace. Optional modules add a customer portal branded with the business’s logo and colors, ticket intake and tracking, invoicing, employee administration and time recording, file management, customer messages, reminders and route planning. Teams can assign roles and permissions, while customers can view services, update their details and submit requests through the portal. The hosted SaaS runs in a browser on computers, tablets and phones, without software installation or a server to operate. Plans are based on administrative user access; portal customers do not use those seats. Businesses can add or remove modules as needed.
