LEFT LEDGER RENTAL / PRODUCT WHITE PAPER

From equipment out
to revenue accounted for.

A rental contract is a working record. Equipment moves, dates change, and billing continues long after the original order. Left Ledger Rental brings that work together inside NetSuite.

01 / THE WORKING CONTRACT

One contract, through every stage.

Some rentals last a day. Others stay open for years and contain hundreds of lines. The contract provides a common record for customer requirements, equipment activity and billing details throughout that life.

1

Set up

Enter customer requirements, purchase order, terms, contacts, locations, shipping instructions and estimated dates in a consistent entry form.

2

Work the lines

Add equipment and quantities, review rates and included accessories, select serials where applicable, and manage delivery and return activity.

3

Review and close

Review transactions, identify remaining billing work, and maintain fully billed and archived status as the contract reaches completion.

Viewing a contract emphasizes performance and outstanding work. Editing its details uses an ordered form. The Items area supports day-to-day refinement, while Transactions provides the records behind the numbers. Service integration is a separate consideration to scope for each implementation.

02 / THE RENTAL BILLING ENGINE

The value continues after delivery.

Getting equipment onto an order is only the beginning. The recurring work is knowing what should bill, for which period, and what remains to be reviewed when equipment comes back.

Left Ledger Rental maintains line-level rates and billing dates alongside delivery and return activity. The production invoicing process evaluates eligible rental lines against the configured billing interval, considers billing start or prior invoice timing, and generates NetSuite transaction records where applicable.

Separate the operational dates

Delivered and returned dates describe equipment movement. Billing start and billing end describe the billing window. Keeping these distinct allows the record to reflect commercial arrangements without losing the movement history.

Support recurring review

Scheduled processing assesses rental age against the configured interval. Next-invoice information and processing logs help staff investigate contracts that need attention rather than relying solely on memory or spreadsheets.

A returned item can still require final billing review. A contract can contain lines at different stages. Rates, dates, completion flags and invoice history must be considered together when reviewing the remaining work.

Confirm the rules with your business.

Daily, weekly and cycle rates, interval settings, partial periods, exceptions and final billing should be reviewed using representative contracts before launch. The website displays example rates and illustrative billing history; it does not execute or validate the production billing engine.

03 / EQUIPMENT ACCOUNTABILITY

Know what went out, and what came back.

In the live system, rental delivery and return generate inventory transfers between the shop’s available inventory and rented-out inventory. These movements support visibility into unit location and inventory value, with linked records available for follow-up and reconciliation.

Identify the right equipment

Serialized equipment can be associated with its specific serial number. In a configured scanning workflow, a barcode lookup can identify an item or the exact serialized unit to add to the order.

Document condition

Photos Out and Photos In associate images and captions with the rental line and direction. They give staff a visual reference for accessories, equipment condition and return conversations.

Line controls follow the rental stage: delivery selection before recorded delivery; return and service selection while equipment is out; completed movement selections closed after return. Condition documentation supports the operating record without replacing inspection or reconciliation procedures.

04 / MANAGEMENT VISIBILITY

Start with the question that needs an answer.

Executive overview

Review rental billing trends, equipment out, store contribution, customer concentration and collection exposure. Operational attention lists help direct investigation toward billing dates, expected returns and final billing review.

Customer overview

Move from a loaded contract to the customer’s broader rental relationship: billing history, equipment mix, equipment currently out and searchable contract history.

Contract filters narrow the working list. Item filters help staff focus on awaiting delivery, equipment out, returned lines or lines needing attention. Counts distinguish rental lines from units so a high-quantity line is not mistaken for a single unit.

Dashboard flags are prompts to investigate. A scheduled date being reached does not by itself prove an invoice was missed. Financial charts in this demo use separate, fictional historical data and are not posted transactions from your browser activity.

05 / EXPLORE THE DEMONSTRATION

A practical way to evaluate the workflow.

The starting dataset includes 25 contracts, 10 fictional customers and 16 equipment items, with variation in contract age and rental stage.

  1. Find a contract. Add filters to the search canvas, configure them and select Apply.
  2. Explore the work. Open a contract, review its overview, then use Items to inspect dates, rates, quantities and status.
  3. Add equipment. Search the catalog, enter quantities on multiple items and add them together. Demo-added lines are quantity-based and do not allocate a real serial.
  4. Try condition photos. Open Photos Out or Photos In, add an image, enter a caption and save it in your browser. Sample image captions can also be edited.
  5. Review the outputs. Print rental out and rental in assemble local PDFs and open a new tab. Use Customer to see the broader rental relationship.

Your browser, your demonstration.

Visitor photos are never uploaded to Left Ledger. Edits and uploaded images stay in this browser when browser storage is available. Clearing browser data or resetting the demo removes local work.
