Pros & Cons
Invoice2go
Pros
Purpose-built for mobile invoicing on the go
Multiple payment methods with decreasing card fees on higher tiers
Integrates with QuickBooks and Xero for accounting sync
30-day free trial with money-back guarantee on all plans
Backed by BILL, a larger, established financial operations company
Cons
Starter and Professional plans cap the number of invoices per year
Card payment fees (2.9%-3.5%) are on top of the subscription cost
Phone support only available on the top Premium tier
Now a subsidiary product rather than an independent company, which can mean shifting roadmap priorities
class-systems
Pros
Purpose-built for language schools rather than a generic school system adapted to the niche
Covers the full operational stack in one platform: enrolments, academics, finance, and accommodation
35+ years of specialization serving the language-school sector
Includes GDPR-friendly online booking and parental consent forms
Cons
Pricing isn't published, so schools must book a demo to get a quote
Built specifically for language schools, so it's not designed for other education verticals
No public free trial or self-serve signup — onboarding goes through a sales demo
