Choose by workflow, not by the number of menu items
The best plan is the smallest one that protects the work your shop cannot afford to lose. A single counter moving away from paper usually needs dependable job cards, customer history, and invoicing first. A growing service center benefits when barcode intake, WhatsApp updates, inventory, technician ownership, payroll, analytics, approvals, and QC become part of the same daily process.
Start by listing where information currently breaks: devices that cannot be found, estimates approved only in chat, parts leaving stock without a ticket, payments reconstructed at closing time, or warranty returns with no evidence. Match the plan to those failures before comparing headline feature counts.
