How We Saved 15 Hours Per Week for an E-commerce Client

When we started working with this e-commerce client, the team was spending 15+ hours per week on repetitive manual tasks. In 3 weeks, we implemented 3 simple automations that completely eliminated this work.

Initial situation

The client operated an online store with ~200 orders per week. Daily processes included:

• Manual invoicing: 3-4 hours/week generating invoices in SmartBill
• Stock updates: 4-5 hours/week manually syncing between site and warehouse
• Follow-up emails: 5-6 hours/week manually sending review requests
• Reporting: 2-3 hours/week compiling data from multiple sources

Total: 15-18 hours per week on repetitive work that didn't generate direct value.

Automation #1: Instant invoicing

Problem: Each order required manual invoice generation in SmartBill, then sending via email to the customer.

Solution: We connected Stripe (payment processor) directly with SmartBill via webhooks. When a payment is confirmed:

1. Stripe webhook triggers a serverless script
2. Script extracts customer and order data
3. SmartBill API automatically generates the invoice
4. PDF invoice is instantly sent to customer's email

Result: 0 minutes on invoicing. Customer receives invoice within 30 seconds of payment.

Automation #2: Real-time stock sync

Problem: Stock was manually updated in a Google Sheet, then transcribed to the site. Overselling risk was constant.

Solution: We created a bidirectional integration:

• Google Sheet becomes the "single source of truth" for inventory
• Any Sheet change automatically updates the website (via API)
• Any site sale automatically decrements the Sheet
• Automatic alert when stock drops below critical threshold

Result: Zero stock errors in 6 months. Time saved: ~5 hours/week.

Automation #3: Post-purchase email sequence

Problem: Client was manually sending follow-up emails requesting reviews. Inconsistent and time-consuming.

Solution: 3-step automated flow, triggered by order status:

1. Delivery day: Confirmation email with usage instructions
2. Day 7: Follow-up email with review request + direct link
3. Day 30: Email with personalized recommendations (cross-sell)

Result: Review rate increased from 3% to 12%. Time saved: ~6 hours/week.

Investment ROI

Conclusion

Automation doesn't mean complicated technology. It means identifying repetitive tasks and eliminating them with simple solutions. These 3 automations cost less than 2 months of manual work—and save time every day, forever.
