In their own words
SaaSFlow
SaaSFlow is a finance cockpit for SaaS companies that combines real-time P&L, subscription analytics, and forecasting in one data layer. It categorizes transactions, calculates P&L, and lets users assign transactions to periods for accrual reporting. Subscription metrics include MRR, ARR, CMRR, revenue movements, logo and revenue churn, customer lifetime, and LTV/CAC. Planning tools forecast cash flow and runway, support budgets and plan-versus-actual comparisons, and update forecasts as actual data arrives. Named integrations include Stripe, HubSpot, Finway, Pleo, DATEV Payroll, and Slack; some connect live while others rely on monthly export uploads. Users can connect Claude, ChatGPT, Cursor, or their own agents via MCP, or use a public REST API and CLI. The maker says the product is for decision-making rather than compliance and operates separately from accounting systems. The free plan includes all features, unlimited users, and unlimited data sources up to €120k ARR (€10k MRR). Pro costs €100 a month with annual billing.
SimpleSubscription
SimpleSubscription is a Shopify subscription management app for merchants, covering recurring billing, storefront subscriptions, and a customer portal. Its Subscribe & Save widget supports flexible discounts, delivery frequencies, annual billing, and Shopify native checkout. Subscribers can skip, pause, swap, or cancel subscriptions, change frequency, and update payment methods in the portal. The app retries failed payments and sends reminder emails on every plan, including Free. Shopify Sidekick AI features let merchants ask about subscription data, run subscriber actions with a confirmation step, and navigate to app editors. Migration options include Appstle, Seal, Recharge, Bold, Loop, and Skio, as well as CSV import and API migration. Plan caps count active subscribers only; paused, cancelled, and expired subscriptions do not count. SimpleSubscription says it charges no transaction fees, though Shopify’s standard payment processing still applies. Free includes up to 100 active subscribers; Growth costs $39 a month and Premium costs $99 a month. The pricing note lists a 14-day trial; annual billing options are advertised for paid plans.
