They serve different purposes. Lifetimely excels at customer LTV analytics and cohort analysis - understanding customer behavior over time. Lynk excels at real-time product profitability with accounting-grade accuracy. Many merchants use both: Lifetimely for marketing insights, Lynk for operational profit visibility.

Lifetimely uses the COGS you manually entered when you set up products. If your vendor raised prices 6 months ago, Lifetimely doesn't know. Lynk pulls actual costs from your QuickBooks vendor invoices, so you always see real margins - not estimates from last year.

Absolutely. Many merchants use Lifetimely for LTV and cohort analytics while using Lynk for accurate product profitability and QuickBooks sync. They complement each other well - Lifetimely for customer insights, Lynk for financial accuracy.

Lynk includes customer-level profitability and basic LTV metrics. For deep cohort analysis and advanced LTV modeling, Lifetimely is more specialized. For accurate profit per product and accounting integration, Lynk is the better choice.

Lynk unifies Shopify, Amazon, and wholesale into a single P&L view with proper cost allocation. Lifetimely is Shopify-focused. If you sell across channels, you need Lynk to see unified profitability.

Lynk has native QuickBooks and Xero integration. Orders sync automatically, COGS come from actual vendor invoices, and your profit dashboard always matches your accounting. Lifetimely doesn't connect to accounting software at all.
