What is CartFlows?
Free and Pro ship in lockstep pairs, and this one is all about WooCommerce bundles.
CartFlows releases the free plugin and the Pro add-on as same-day pairs, roughly every two to six weeks. The August pair centers on WooCommerce Product Bundles: Pro 3.1.3 makes bundles work as upsell and downsell offers, while free 3.1.4 fixes how bundle products render across the funnel builder. The previous pair brought A/B split testing to order bumps and cut funnel load times.
What is Polar?
Polar fills out the merchant-of-record toolkit B2B SaaS actually needs — meters, multi-currency, team accounts.
Polar's recent run is a focused buildout of B2B billing primitives that compete directly with Stripe Billing and Lago. Meter Units add value-multiplier support so usage metrics can be ingested in raw counts and priced in customer-friendly units. Pending subscription changes are now visible in both dashboard and customer portal. Multi-currency product pricing lets merchants set per-currency prices on the same product. Team Member Management for B2B brings owner/billing-manager/member roles. Every entry appears duplicated in the feed.

CartFlows
5.0E-COMM
Free and Pro ship in lockstep pairs, and this one is all about WooCommerce bundles.
◆ Current state
CartFlows releases the free plugin and the Pro add-on as same-day pairs, roughly every two to six weeks. The August pair centers on WooCommerce Product Bundles: Pro 3.1.3 makes bundles work as upsell and downsell offers, while free 3.1.4 fixes how bundle products render across the funnel builder. The previous pair brought A/B split testing to order bumps and cut funnel load times.
◆ Where it's heading
The work is converging on post-purchase revenue mechanics — order bumps, upsells, downsells, cart recovery — rather than on funnel authoring. Bundles support closes a real gap, since the highest-value WooCommerce catalogs sell bundled SKUs and previously could not put them in an offer slot. Analytics and attribution accuracy keep getting patched release after release, which suggests measurement is the weak link customers keep reporting.
◆ Prediction
Expect the next pair to follow the same shape: a Pro feature extending offer types or A/B testing to more of the funnel, with the free plugin catching the display and compatibility fixes that follow.
Polar
6.3E-COMM
Polar fills out the merchant-of-record toolkit B2B SaaS actually needs — meters, multi-currency, team accounts.
◆ Current state
Polar's recent run is a focused buildout of B2B billing primitives that compete directly with Stripe Billing and Lago. Meter Units add value-multiplier support so usage metrics can be ingested in raw counts and priced in customer-friendly units. Pending subscription changes are now visible in both dashboard and customer portal. Multi-currency product pricing lets merchants set per-currency prices on the same product. Team Member Management for B2B brings owner/billing-manager/member roles. Every entry appears duplicated in the feed.
◆ Where it's heading
Polar is no longer just an indie-developer monetization tool — the recent surface reads like a serious B2B SaaS billing platform. Usage-based pricing primitives (meters with custom units), multi-currency, scheduled subscription changes with customer-portal visibility, and B2B team management collectively close the gap with the standard checklist enterprise buyers compare against. The trajectory is clear: target SaaS companies that previously had to choose between Stripe Billing's complexity and a smaller-but-simpler tool.
◆ Prediction
Expect more usage-based primitives — tiered metering, prepaid credits, free-tier graduation flows — given the meter-unit foundation just landed. Tax-handling improvements (more jurisdictions, automated reconciliation reports) are likely next given the multi-currency push. SOC 2 / SAML enterprise checklist items will probably become visible too if the B2B push continues.
