1. Start With a Simple Shipping Invoice Template

Before you bring in automation, you need a clean base.

In Google Sheets:

1. Create a new Sheet and add tabs for Invoice, Items, and Clients.
2. On Invoice, lay out the essentials: logo, company info, client info, ship-to address, invoice no., date, terms.
3. Add a line-item table with columns for description, quantity, unit price, taxes, and total.
4. Use formulas like =B12*C12 for line totals and =SUM(F12:F40) for subtotals.
5. Turn it into a template by duplicating the tab each time or using a simple Apps Script to create new copies.

In Excel:

1. Open a blank workbook and design the same structure.
2. Use named ranges (e.g., Subtotal, TaxRate) to make formulas easier to manage.
3. Add data validation lists for payment terms or shipping methods.
4. Save it as an .xltx template so your team always starts from a consistent file.

Pros (Manual): Full control, no setup cost, easy to adjust fields. Cons (Manual): Time-consuming, error-prone, scales poorly as orders grow.

2. Manual Workflow: Step-by-Step From Order to Invoice

Here’s what most teams quietly do every day:

1. Pull order data from email, Shopify, a freight portal, or a TMS.
2. Copy customer info into the Bill To and Ship To sections.
3. Enter shipment details: lanes, loads, SKUs, quantities, weights.
4. Calculate charges for base freight, accessorials, fuel surcharge, and taxes.
5. Save as PDF and attach to an email.
6. Update a tracker (often another Sheet/Excel file) to mark the invoice as sent.

This works when you’re small. But once you’re doing dozens or hundreds of shipments a week, this workflow becomes a tax on your smartest people. Every copy-paste is a chance for a typo that delays payment.

3. Introducing an AI Computer Agent Into the Loop

This is where Simular’s AI computer agents change the game. Instead of coding rigid RPA scripts, you give the agent a goal like:

“For each new shipment, create a shipping invoice from our template, fill in all fields from our order sources, save a PDF, email it, and log it in our tracker.”

Because Simular Pro can use the computer like a human, it can:

• Open Google Sheets or Excel.
• Duplicate your invoice template tab or file.
• Paste in customer and lane data pulled from web portals or emails.
• Apply existing formulas to compute totals and taxes.
• Save and organize invoice PDFs in your drive.
• Update a master log and send the invoice to your customer.

You keep your familiar tools; the agent just takes over the clicks and keystrokes.

4. Semi-Automated: You Prepare, the Agent Finishes

If you’re not ready to go fully hands-off, start with a hybrid:

1. A human confirms shipment details in a simple "staging" sheet—order ID, customer, lane, accessorials.
2. The AI agent periodically checks that staging sheet.
3. For each approved row, it:
   • Opens your invoice template in Sheets or Excel.
   • Fills in fields from the staging data.
   • Generates and names a PDF (e.g., INV-2025-00123_ClientA.pdf).
   • Emails it to the billing contact and logs it as sent.

Pros:

• Human sanity-check stays in place.
• Major time savings from automated document creation.
• Easy to roll out without changing your accounting system.

Cons:

• You still need someone to maintain the staging data.
• Not yet fully autonomous end-to-end.

5. Fully Automated: From Order Source to Paid Faster

As you gain confidence, you can let an AI computer agent handle more of the workflow:

End-to-End Flow Example:

1. Order ingestion: The agent reads new orders from your TMS, e‑commerce admin, or even structured emails.
2. Data normalization: It cleans addresses, standardizes accessorial codes, and matches customers to your master list.
3. Invoice creation: Using your Google Sheets or Excel template, it:
   • Opens or duplicates the base template.
   • Populates all header and line-item fields.
   • Confirms totals and taxes via built-in formulas.
4. Quality checks: It verifies mandatory fields (BOL, PO, terms) are present and flags any exceptions to a human.
5. Delivery & logging: It saves the invoice, emails it, and updates a central AR tracker.

Pros (Automated):

• Scales to thousands of invoices without new headcount.
• Dramatically reduces data entry errors.
• Frees operators, founders, and account managers to focus on higher-value work.

Cons (Automated):

• Requires a bit of upfront design for your templates and rules.
• You need a brief onboarding period to teach the agent your exact process.

6. Choosing the Right Mix for Your Business

If you’re a small agency or freight broker, you might start with:

• Manual templates in Google Sheets or Excel for 100% control.
• A Simular AI agent that only handles repetitive parts: duplicating templates, exporting PDFs, sending emails.

If you’re a growing logistics company or e‑commerce brand:

• Move quickly toward an end-to-end AI-driven workflow.
• Keep humans focused on exceptions—disputes, special billing rules, or VIP accounts.

The pattern is simple: keep your shipping invoice template as the single source of truth, and let the AI computer agent become your tireless billing coordinator, quietly stitching data from everywhere into clean, reliable invoices.
