Lifetimely is the closest competitor to By the Numbers on scope: both apps cover LTV, cohorts, and customer analytics for Shopify stores. The differences that matter are price at your order volume, what happens after the analysis, and how the trial works.
The short version: Lifetimely goes deeper on profit accounting. By the Numbers covers the same customer analytics, then adds AI segmentation and pushes those segments to Klaviyo, Meta, Google, and TikTok - and costs roughly half as much at typical volumes.
$19/mo up to 500 orders, $39/mo up to 2,000, $89/mo up to 5,000, topping out at $299/mo unlimited. Every plan includes every report. The 14-day trial never takes a card, so it cannot auto-charge you.
Free up to 50 orders/mo, then paid plans that scale with volume: $149/mo at up to 3,000 orders, $499/mo at up to 15,000, up to $999/mo unlimited. Amazon data is a $75/mo add-on. The 14-day trial takes a card up front; you are charged unless you cancel.

Where Lifetimely wins
- True profit accounting: daily P&L with COGS, shipping, fees, and ad spend baked in. By the Numbers reports revenue-side analytics, not a full P&L.
- Amazon: if a meaningful share of your revenue is on Amazon, Lifetimely's paid add-on covers it.
- Industry benchmarks against their customer base are built into paid plans.
Where By the Numbers wins
- Price at every realistic volume: at 3,000 orders/mo you pay $89 against $149, and the $19 entry plan has no Lifetimely equivalent beyond their 50-order free tier.
- Activation, not just analysis: build a segment from 75+ filters and it stays synced hourly to Klaviyo, Meta, Google Ads, and TikTok. Lifetimely tells you who your best customers are; By the Numbers also gets that audience into your ad platforms.
- The RFM loyalty matrix: a 16-cell recency/frequency/monetary grid updated nightly, with one-click sync of any cell to a Klaviyo flow.
- A trial that cannot bill you by accident: no card up front, ever.
Which one fits your store?
Pick Lifetimely if your core question is "what is my true profit per day, after every cost?" and you sell meaningfully on Amazon. Its P&L is the best in this category.
Pick By the Numbers if you want the same LTV and cohort insight plus segmentation you can actually push to your marketing channels, at roughly half the monthly cost.
