InvoiceFlow for Courier & Delivery Services: Complete Billing Guide

The invoicing system built for same-day couriers, medical delivery services, and last-mile delivery businesses


Courier and delivery billing requires a system that handles multiple client types simultaneously: individual clients who pay per delivery, corporate accounts who need weekly invoices, medical clients with documentation requirements, and e-commerce partners who send daily batches.

InvoiceFlow handles all of these from one Android app. This guide covers how to structure each billing type.

Per-Delivery Invoicing

The most basic delivery invoice documents the delivery details and the charge clearly:

“Delivery Services — [Date]: Pickup: [Address] | Delivery: [Address] Service Type: Same-day delivery, standard Distance: 8.2 miles Base rate: $18.00 Fuel surcharge (8%): $1.44 Total: $19.44”

Pre-build your delivery rates in InvoiceFlow’s service catalog. Standard rate options to define:

Having these pre-built means every invoice calculates from your established pricing — no guessing or inconsistency.

Weekly Corporate Account Invoicing

Regular accounts bill themselves every month — the law firm and pharmacy runs go out without you lifting a finger.

Corporate clients — law firms, medical suppliers, office service businesses — need a formatted weekly or monthly invoice they can process through their AP systems. The invoice needs to show:

“Courier Services — [Law Firm Name] — Week of June 2-6, 2026: Monday June 2: Document delivery, 3 stops (courthouse, county recorder, client office): $47.00 Tuesday June 3: Urgent contract delivery, downtown to Scottsdale: $38.00 Wednesday June 4: Document delivery, 4 stops: $56.00 Thursday June 5: Emergency courthouse filing: $42.00 Friday June 6: End-of-week document run, 5 stops: $65.00 Weekly subtotal: $248.00 Fuel surcharge (8%): $19.84 Total: $267.84 — Payment Terms: Net-7”

Set up recurring weekly invoice templates in InvoiceFlow for each corporate account. Fill in the week’s deliveries each Friday and send. Payment arrives predictably within Net-7 terms.

Medical Delivery Documentation

Medical and pharmaceutical clients often require fields that standard invoices do not include: client reference numbers, recipient confirmation (signed delivery), and description of goods transported. Use InvoiceFlow’s custom fields to add:

These fields make the invoice processable by healthcare AP departments without follow-up. Medical clients on net-15 terms process faster when documentation is complete.

E-Commerce Batch Delivery Invoicing

The month's runs, an 8% fuel surcharge and fragile-handling — each on its own line, account reference in custom fields.

Local e-commerce clients who send regular delivery batches need a batch invoice format where each line item maps to an order they can match to their records.

“Local Delivery Batch — [Store Name] — June 6, 2026: Order #E001 — [Zone A Address]: $14.00 Order #E002 — [Zone A Address]: $14.00 Order #E003 — [Zone B Address]: $16.00 (extended zone) Order #E004 — [Zone A Address]: $14.00 […12 deliveries total…] Delivery subtotal: $174.00 Fuel surcharge (8%): $13.92 Total: $187.92”

Each order number is traceable. Any delivery issue is identifiable. This level of transparency builds trust with e-commerce clients and leads to long-term account relationships.

Fuel Surcharge Tracking

Fuel is a major variable cost in delivery businesses. A fuel surcharge applied consistently to all invoices passes a portion of this cost to clients — which is standard and expected in the delivery industry.

Set your fuel surcharge as a percentage line item in InvoiceFlow. Review and adjust quarterly based on average fuel costs. Apply it automatically to every invoice. For a delivery business running 2,000+ miles per week, even a modest 8% fuel surcharge recovers a meaningful portion of fuel expense.

Waiting Time and Detention Billing

Invoice Flow app documents of a courier service — monthly accounts for a law firm, a medical lab and a pharmacy plus a last-mile subcontract
Law firm, medical lab, pharmacy and a last-mile subcontract — every account you serve, billed and tracked in one place.

When you arrive at a pickup and the package is not ready, or when you arrive for delivery and the recipient is unavailable, you are entitled to charge for the delay. Set a waiting time policy:

Document the arrival time and the time you were able to proceed. Include the waiting time as a line item on the invoice. This policy also changes client behavior: pickups are ready when you arrive.
