Twilio A2P / Toll-Free SMS Compliance Expert — ISV Setup for Review-Request SaaS (US)

We’re building Local Business Manager, a SaaS platform for marketing agencies that manage local businesses (Google Business Profile management, rank tracking, review requests). One feature sends review-request SMS and email to a business’s customers on behalf of that business. We need an expert in US A2P messaging compliance to design and set up the registration model so we can launch this feature legally and without deliverability problems. What we already have Upgraded Twilio account; Trust Hub Primary Customer Profile approved (currently set as Direct Customer — we’re changing it to ISV Reseller/Partner) A registered A2P 10DLC brand and campaign for our own company’s traffic Several toll-free numbers, some already verified for other use cases Legal entity: US LLC (Wyoming) with EIN, live website with privacy policy, terms and data-deletion pages A developer (Claude Code / Python / Next.js) who will implement whatever you specify What we’re trying to achieve Agencies add a client business in our app and start sending review-request texts with as little friction as possible — ideally the same day Two sending scenarios: (a) customers who opt in through our own hosted consent forms, QR codes and keyword replies; (b) customer lists the client uploads (customers they’ve served, with consent they collected) Per-client isolation so one client’s complaints don’t affect others Toll-free as the primary channel; 10DLC possibly later as a “local number” upgrade What we need from you A 60–90 minute consultation reviewing our situation and telling us plainly what the compliant model is in late 2026 for scenario (a) and scenario (b): platform-level verification under the ISV exception vs. per-client toll-free verification vs. per-client 10DLC. If you know how established review platforms send from platform-owned toll-free numbers without per-client verification, we want to understand it. A written registration plan: Trust Hub structure (ISV profile, subaccounts, secondary profiles), which verifications to file and with what wording (use case category, use-case summary, sample messages, opt-in evidence, Additional Information), the exact consent language for our forms, and what our Terms/Privacy pages must contain. Review of our actual submissions before we file them, and help resolving rejections (30474, 30506, etc.) if they happen. Guidance on the Twilio Compliance Embeddable / Tollfree Verifications API flow so our developer can automate per-client verification inside our onboarding. Operational rules: opt-out handling, quiet hours, volume caps, monitoring, and what triggers carrier filtering or account action. You should have Hands-on experience filing and getting approved Twilio toll-free verifications and 10DLC campaigns for an ISV / multi-tenant platform (not just for a single business) Working knowledge of CTIA guidelines, TCPA consent rules, carrier filtering behaviour and Twilio’s 2026 changes (business registration number requirement, separate privacy/terms URLs) Ideally, experience with review-request, appointment-reminder or similar “send on behalf of merchants” products Experience with Bandwidth, Telnyx or Sinch is a plus Engagement Start with a paid consultation call (hourly). If it goes well, a fixed-price package for the written plan and submission reviews, with ongoing hourly support during launch. We’re in Central European time; calls in US morning / EU afternoon work best. To apply, please answer briefly: Describe an ISV/multi-client Twilio setup you’ve registered. How many end businesses, toll-free or 10DLC, and how long approvals took. In your experience, can a platform verify toll-free numbers under its own name and send on behalf of many businesses? Under what conditions? Have you handled a Twilio rejection with error 30474 or 30506? What fixed it? Your hourly rate and availability this month. Please don’t send generic SMS-marketing or Twilio-development proposals; this is a compliance and registration role.
