Case study
A complete online rental booking platform, built from scratch.
For BS&W Trailer Rentals of NC, we built a bespoke trailer-reservation system on WordPress & WooCommerce — online booking, a real availability engine, damage-waiver upsells, ID capture, integrated card payments, and 24/7 contactless pickup with rotating lock-box codes.
The customer journey
Reserve a trailer in under a minute
Every screen below is the real product — branded, responsive, and built around how this business actually rents.
Branded storefront
A storefront that looks the part
Custom WordPress + WooCommerce theme in the client’s brand — fast, mobile-first, and SEO-ready. Optimized hero imagery cut the homepage payload by ~95%.
Browse the fleet
Pick the right trailer in seconds
Every unit is a live product with its own day-rate, deposit, specs and photos — managed from the admin, no developer needed.
Availability + live pricing
An iPhone-proof booking calendar
A hand-built button-grid calendar (no native date picker to hijack on mobile) with real-time availability, conflict detection, and a running itemized quote as you choose dates.
Damage-waiver options
Tiered coverage, clearly priced
Optional per-day damage waivers with coverage caps — upsold cleanly at the point of booking, fully configurable by the owner.
Transparent checkout
No-surprises itemized total
Rental days, coverage, refundable deposit and taxes broken out line-by-line before the customer ever reaches for a card.
Contactless pickup
A one-time lock-box code, on the spot
After payment, the system releases a rotating lock-box code so renters can grab their trailer 24/7 — no counter, no waiting, no shared keys.
Built for the phone in the cab
Flawless on mobile
Most rental customers book from a phone. The calendar is a custom button grid — specifically engineered so mobile browsers can’t hijack the date fields — so tapping pick-up and return dates just works, every time.
Under the hood
Not a template — a real system
The booking flow is powered by a custom plugin we wrote for this business.
✓Custom rental-day engine
Business-specific day math — after-4PM pickups roll to the next day, return-by-7PM rules — timezone-correct.
✓Real availability
Per-trailer conflict detection prevents double-bookings; the calendar only offers days that are actually free.
✓ID & document capture
Driver’s-license and registration upload with private, off-web storage and a retention policy — PII handled with care.
✓Rotating lock-box codes
A managed code pool releases a unique code per rental, only after payment and verification.
✓Integrated card payments
Live merchant gateway with tokenized (PCI-safe) card capture, plus a custom refund/void tool with a full audit log.
✓Owner admin suite
Reservations, customers, trailers, coverage tiers, lock-box codes and reporting — all in one dashboard.
