B

Backorder

Procurement

A backorder is a supplier notification that an ordered item cannot ship immediately because stock is temporarily unavailable, but will be fulfilled once stock is replenished. It arises after an order is placed, distinct from a standard lead time agreed at ordering.

Bill of Materials (BOM)

Operations

A bill of materials (BOM) is a structured list of every material, component, and quantity needed to complete a job or project. It connects the quote to procurement and job costing, ensuring every item is ordered and every cost is tracked.

Bill of Quantities (BOQ)

Operations

A document used in construction and fit-out projects listing the measured quantities of every material, labor type, and task required. Contractors price each line item at their own unit rate to produce their tender bid.

Blanket Purchase Order

Procurement

A long-term procurement agreement with a supplier for recurring supply of specified goods or services at agreed pricing over a set period. Individual call-offs are made against the blanket order rather than raising a separate PO for each transaction.

Break-Even Point

Finance

The level of revenue or sales volume at which a business covers all its costs exactly, with no profit and no loss. Every sale above break-even contributes to profit; every shortfall below means a loss.

Budget Variance

Finance

The difference between a budgeted cost or revenue figure and the amount actually recorded. A negative variance means costs exceeded budget or revenue fell short. Used to monitor job profitability and improve estimating accuracy over time.

C

Call-off Order

Operations

An individual order placed against an existing framework agreement or blanket contract, using pre-agreed terms and pricing without a separate tender or commercial negotiation for each purchase.

Cash Flow Forecast

Finance

A cash flow forecast is a projection of the cash a business expects to receive and pay out over a future period - typically a rolling 4, 8, or 13-week window. It tracks when money actually moves, not just when revenue is recorded.

Commissioning

Operations

The process of testing, verifying, and documenting that an installed system performs to its design specification before client handover. A distinct phase from installation, and the trigger for final payment on most AV, electrical, and renewables projects.

Consignment Stock

Procurement

Inventory that a supplier physically places at a customer's premises while retaining ownership until it is consumed, used in production, or sold. Payment is triggered at the point of use, not on delivery.

Contingency

Operations

A budget reserve included in a project quote or contract to cover unpredictable costs. Expressed as a percentage of total project value - typically 5-10% for simple jobs and 15-20% for complex or high-risk scopes.

Contribution Margin

Finance

The amount remaining from job or order revenue after all variable direct costs are deducted. Shows how much each job contributes to covering fixed overhead and generating profit, before fixed costs are applied.

Cost of Goods Sold (COGS)

Finance

The total direct costs incurred to deliver a product or complete a job, including materials, direct labor, and sub-contractor costs. Revenue minus COGS equals gross profit - the measure of whether the work itself is profitable.

Credit Control

Finance

The process of managing customer credit to minimize overdue debt and bad debt losses. Includes setting payment terms, monitoring invoice aging, and running a structured chase sequence for outstanding invoices.

Credit Note

Finance

A credit note is a document issued by a seller to reduce or cancel a previously raised invoice, recording an agreed reduction in the amount a customer owes for returned goods, pricing errors, or partial refunds.

Creditor Days

Finance

The average number of days a business takes to pay its suppliers, calculated as trade creditors divided by annual purchases multiplied by 365. Also called Days Payable Outstanding or payables days.

Critical Path

Operations

The longest sequence of dependent tasks in a project that determines the earliest possible completion date. Any delay to a critical path task delays the whole project by the same amount. Tasks off the critical path have float - time buffer before their delay affects the end date.

Cross-Selling

Sales

A sales technique where a seller recommends complementary or related products to a customer already making a purchase, with the aim of increasing the total transaction value and deepening the customer relationship.

Customer Acquisition Cost

Sales

The total amount a business spends on sales and marketing to win one new customer, calculated by dividing total acquisition spend by the number of new customers gained in the same period.

Customer Lifetime Value (CLV)

Sales

The total revenue a business can expect from a single customer across the full length of their relationship, calculated by multiplying average order value by purchase frequency and customer lifespan.

Customer Retention Rate

Sales

The percentage of existing customers who place at least one repeat order in a defined period. Calculated as: (customers at end of period minus new customers acquired) divided by customers at start, multiplied by 100.

D

Day Rate

Operations

A day rate is a fixed daily charge for a contractor, tradesperson, or freelancer's labor - either agreed as a standalone daily fee or calculated from an hourly rate multiplied by the standard working day length.

Daywork Sheet

Industry

A site document used in construction to record the labour hours, materials, and plant used on work instructed and paid at daywork rates. The signed sheet provides a verified basis for billing time-and-materials variations and is required evidence at application for payment.

Debtor Days

Finance

The average number of days it takes a business to collect payment from customers after issuing an invoice. Calculated from outstanding trade receivables and annual credit sales. A key indicator of cash collection speed and credit control effectiveness.

Decoration Method

Operations

The technique used to apply a logo, text, or design to a promotional product. The chosen method directly affects cost per unit, minimum order quantity, lead time, and the artwork format required.

Defects Liability Period (DLP)

Operations

A contractual period after practical completion - typically 6 to 24 months - during which the contractor must return and fix defects in their workmanship or materials at no charge. The second half of retention is withheld until the DLP ends and defects are certified as made good.

Delivery Note

Operations

A delivery note is a document sent with a supplier shipment that lists the goods included. It lets the buyer check what was received against what was ordered before approving the supplier's invoice for payment.

Drop Shipment

Procurement

An arrangement where a supplier delivers goods directly to the end customer on behalf of the buying business. The buyer handles pricing and customer invoicing; the supplier handles physical fulfillment from their own stock or warehouse.

Dry Hire

Industry

Rental of equipment without an operator or crew. The customer supplies their own technicians to operate and return the kit. Most common in AV and live events hire. Contrasts with wet hire, which includes a qualified operator in the rate.

P

PMS Colour

Industry

PMS (Pantone Matching System) assigns a unique numeric code to each colour. In promotional merchandise, specifying a PMS reference ensures consistent brand colour reproduction across different suppliers, products, and decoration methods.

Payment Terms

Procurement

Payment terms are the agreed conditions defining when an invoice must be paid, any early-payment discount available, and the consequences of late payment. Common formats include Net 30, Net 60, due on receipt, and milestone-based stage payments for longer projects.

Pipeline Value

Sales

The total monetary value of all open quotes and opportunities in a sales pipeline at a given moment - representing the maximum revenue available if every live deal were won. Used to assess whether there is enough work in play to hit targets.

Practical Completion

Operations

A formal construction contract milestone confirming works are substantially complete and the client can take possession, even if minor defects remain. Triggers the first retention release, the defects liability period, and the final account process.

Preferred Supplier

Procurement

A preferred supplier is a business or individual that has been pre-assessed and approved for repeat purchasing. Preferred status means agreed pricing, confirmed payment terms, and known lead times are already on record, eliminating the vetting cycle on each new order.

Pro Forma Invoice

Sales

A preliminary document sent to a customer before goods are delivered or work is complete, stating the expected price and terms. Used to request advance payment or a deposit. A pro forma invoice is not a tax invoice and does not record a completed sale.

Progress Billing

Finance

A method of invoicing where a contractor or supplier bills for work completed to date at regular intervals throughout a project, rather than raising a single invoice at completion. Keeps cash flowing and reduces financial exposure on long-running jobs.

Proof Approval

Operations

The formal customer sign-off on a supplier-produced visual showing exact logo placement, colors, and decoration specification before production begins. Required for all custom-decorated promotional products, branded apparel, and printed items.

Provisional Sum

Operations

An estimated allowance included in a construction or fit-out contract for work that is known to be required but cannot be fully defined or priced at the time of contract signing. Formally instructed and adjusted to actual cost in the final account.

Purchase Order

Procurement

A formal written document issued by a buyer to a supplier authorizing the purchase of specific goods or services at an agreed price. Creates a binding agreement once accepted and locks the supplier price for the order.

Purchase Requisition

Procurement

A purchase requisition is an internal document submitted by an employee to request approval to make a purchase. Once approved, it authorizes the procurement team to raise a purchase order with the supplier.

S

Sales Forecast

Sales

A projection of future revenue based on current open quotes, historical win rates, and known repeat orders - used to plan capacity, manage cash flow, and set realistic revenue targets.

Sales Velocity

Sales

A metric that measures how fast a business converts pipeline opportunities into revenue, calculated by multiplying deal count, average deal value, and win rate, then dividing by average sales cycle length in days.

Scope Creep

Operations

Scope creep is the gradual expansion of a project's agreed work without formal approval or price adjustment. It occurs through informal additions and verbal instructions that are actioned without a written change order, eroding project margin over time.

Scope of Works

Operations

A written document that defines the specific tasks, deliverables, and boundaries of a project or contract, establishing what is included in the agreed price and what is explicitly excluded. Used by contractors, AV integrators, and installers to prevent scope creep and support variation orders.

Service Level Agreement

Operations

A formal agreement between a service provider and customer that defines the expected standard of service, including response times, performance metrics, and remedies if those standards are not met.

Setup Fee

Operations

A one-time charge applied by a supplier to prepare decoration equipment or tooling for a specific design. Charged per method, per color, or per location, and appears on the supplier invoice separately from the per-unit run charge.

Snag List

Operations

A document listing outstanding defects, incomplete work, or minor failures identified at the end of a project before formal handover. Used in construction, AV installation, and furniture fitting to define what must be resolved before final payment is released.

Specification

Operations

A written document defining the exact requirements for a product, material, or service before procurement begins. A specification records product codes, dimensions, finishes, materials, and performance standards to prevent ambiguity and reduce costly errors between quote and delivery.

Spot Purchase

Procurement

A one-off unplanned purchase made outside established supplier agreements, typically on the open market to fulfil an urgent need when preferred suppliers cannot deliver in time.

Stage Payment

Finance

A stage payment is an agreed amount invoiced when a project reaches a defined milestone rather than at job completion. Stage payments help project-based businesses manage cash flow across jobs that span weeks or months.

Sub-contractor

Operations

A sub-contractor is an individual or business engaged by a main contractor to carry out a defined portion of project work. They operate as a separate commercial entity, supply their own tools and insurance, and submit their own invoice on completion.
