Sending Customized Payment Links via SMS-Magic for Law Firms
How Twopir Consulting enabled automated, personalized SMS payment links through Salesforce & SMS-Magic — improving collections efficiency and client experience for a law firm. Law firms handle sensitive financial transactions daily — retainers, invoices, and outstanding balances — yet many still rely on email or paper-based payment requests that are easy to miss or delay. This case study details how Twopir Consulting implemented a seamless SMS-based payment link solution using SMS-Magic integrated with Salesforce, allowing the firm to send personalized, secure payment links directly to clients' mobile phones. The result: faster collections, reduced manual effort, and a dramatically improved client payment experience.

Five Operational Problems That Delayed Collections — and Five Fixes That Solved Them
Five Implementation Phases That Transformed Collections
Connected SMS-Magic Natively to Salesforce Objects
We configured SMS-Magic natively within Salesforce to access Contact, Matter, and Invoice objects. Dynamic Salesforce fields — client name, matter number, amount due, due date — were mapped directly into SMS templates. We also enabled bi-directional SMS communication, so client replies and confirmations are captured back in Salesforce automatically.
Built Unique, Pre-Filled Payment Links via LawPay / AffinPay API
We integrated the firm's payment gateway (LawPay / AffinPay) to generate unique, client-specific payment URLs — each pre-populated with the invoice amount, client ID, and matter reference — reducing friction at checkout. Links included expiry controls for security, ensuring time-sensitive access to the payment portal.
Deployed a Multi-Step Automated Reminder Sequence
We built Salesforce Flows to trigger SMS messages automatically when invoices were created or became overdue. We designed a multi-step reminder sequence: initial notification → 3-day reminder → 7-day follow-up → final notice. Staff could also manually trigger customized payment SMS from any Invoice or Contact record with a single click.
Created Branded, Compliance-Ready SMS Templates
We created branded, professional SMS templates using Salesforce merge fields for full personalization. Sample message: "Hi [Client Name], your balance of $[Amount] for [Matter Name] is due on [Date]. Pay securely: [Payment Link]". Templates maintained compliance with legal communication standards and included opt-out instructions.
Built Dashboards to Track Every SMS, Click, and Conversion
All SMS activity is logged automatically against Salesforce records — sent time, delivery status, link clicks. We built custom Salesforce dashboards to track open payment balances, SMS delivery rates, and payment conversion. Alerts were configured to notify staff when a payment link was clicked but payment was not completed — enabling targeted follow-up on warm leads.
Payment follow-up used to mean staff spending hours every week tracking down invoices over email. Now Salesforce handles the entire sequence automatically — and when a client taps the link, everything they need to pay is already filled in. Collections that used to drag past two weeks now close in days.

Days to collect — cut by more than half
Average invoice collection time dropped from 14 days to under 5 days after automated SMS reminders replaced email follow-up chains. Clients respond to SMS within minutes, not days.
Reduction in manual payment follow-up work
Automated Salesforce Flows handle the complete multi-step reminder sequence — initial notice, 3-day, 7-day, and final — with no staff involvement, freeing the team for higher-value client work.
Higher payment response rate vs. email
SMS payment links achieved significantly higher open and payment rates compared to generic email reminders — especially for mobile-first clients who respond faster to direct messages.
Manual data entry in the payment workflow
Payment links auto-populate from Salesforce — no copy-paste, no manual entry, no system switching. Every link is generated and sent without staff touching the data.
SMS activity tracked in Salesforce in real time
Every SMS send, delivery status, link click, and payment conversion is logged automatically against the relevant Salesforce record — leadership has full, real-time collections visibility.
Client payment experience from link to receipt
Clients tap the link, land on a pre-filled secure checkout page, and complete payment in seconds — no portal login, no phone call, no friction. The entire journey is seamless from mobile.
