Opsler is an enterprise-grade field service management platform engineered specifically for US-based mid-market SMBs with 5 to 50 employees. Built by software architects with over 7 years of experience in global technology consulting, Opsler moves beyond basic dispatching to solve the "hidden" financial leaks that cost modern trade businesses thousands in lost profit every year. Unlike legacy platforms that prioritize technician convenience over owner control, Opsler was designed to act as a financial guardrail for your business. Key Capabilities - The Invoice Guardrail: Stop "Nice Guy Tech" profit leaks with real-time approval workflows that require owner sign-off on field discounts before an invoice is ever sent to the customer. Blind Inventory Audits: Eliminate "van-shrinkage" with a proprietary inventory logic that forces physical verification of stock, ensuring expensive parts don't disappear between the warehouse and the job site. Revenue Leak Protection: Utilize built-in logic to recover an estimated 3% margin typically lost to unauthorized field-level discounting and inefficient payment processing. OTP-Based Approvals: Ensure 100% estimate accuracy and customer buy-in with One-Time Password (OTP) verification for all field-generated quotes. Zero-Fee Payment Infrastructure: Built-in QR payment support designed to bypass traditional "Software Taxes" and keep more of every dollar in your business.
