The short answer
SMS Avis is a very simple, low-cost tool (€7/month excl. tax) focused on sending Google review requests by SMS, with no filtering or AI. OpenAvis is a complete suite: multichannel collection, negative review filtering, a widget, a public pro page, and AI tools, at €29/month with a free plan.
SMS Avis does one thing and does it simply: send customers a message (SMS, WhatsApp, QR code, or link) that redirects them to your Google Business Profile to leave a review. It is effective and cheap (€7/month excl. tax per location), but with no negative review filtering, no widget, no public pro page, and no AI features. OpenAvis costs more (€29/month with a free plan) but covers the entire local reputation chain.
VS
| Criteria | SMS Avis | OpenAvis |
|---|---|---|
Collection channels Range of request channels | SMS (main), WhatsApp, QR code, and link - messaging-oriented, offers WhatsApp | QR code, email, SMS, and link, plus a QR kit with 6 formats (no WhatsApp) |
Negative review filtering before publication Handle unhappy customers privately | Redirects straight to Google, with no filtering step | Positive reviews redirected, negatives caught privately before publication |
Website widget and public pro page Display your reviews and a showcase without a website | No widget or pro page; just a link you post yourself | Review widget and public pro page (mini-site without a website) |
AI features (visibility, Google Business Profile) AI analysis and listing optimization | No AI features | AI visibility analysis, Google Business Profile optimizer, and AI-generated GBP posts |
Reporter Space (fraudulent reviews) Report a fake review with tracking | No reporting system | Dedicated Reporter Space with status tracking |
Entry price Starting monthly cost | €7/month excl. tax per location - very low, but limited to collection | Free plan, then €29/month - more expensive, but a complete suite |
SMS Avis has the merit of simplicity and a very low price, plus the WhatsApp channel that OpenAvis does not offer. Its limitation is scope: it redirects straight to Google with no filtering, so an unhappy customer publishes their negative review just like anyone else. For anyone who wants to protect their rating and manage their reputation (widget, pro page, AI analysis), the tool quickly shows its limits.
SMS Avis has very low upfront pricing: €7/month excl. tax or €70/year excl. tax per location, with no commitment on the monthly plan and a 7-day free trial on the annual plan. That is cheaper than OpenAvis (Free plan, then €29/month), but SMS Avis is limited to collection, whereas OpenAvis includes filtering, a widget, a pro page, and AI.
