CASE STUDY · SILLA
Silla used paper and Excel to manage furniture sales, then retyped order details into the courier's system. I built an app in about a month. Now the whole company runs through it, from buying stock to customer reviews. Today the team handles about 90 orders a day instead of 20, with the same number of people.
“I work from Thailand and visit trade fairs around the world, and I see the whole business in one click. The company is growing faster than ever, and I have time for other projects.”
THE SAME ORDER, BEFORE AND AFTER
Before the app, each order passed through three or four people and just as many tools. Every time someone copied the details, there was another chance for an error.
An order arrives on the website
Someone has to notice it and print it out.
The details go onto paper
Customer, address, model, color and quantity.
Someone copies them into Excel
Stock records are updated by hand and fall behind.
Someone types them into the courier's system
The address is copied for the third time.
The paper goes to the warehouse
A warehouse worker uses it to find the model and color.
Someone searches across apps for the status
A customer calls, and finding the answer can take up to 15 minutes.
3–8 errors a week: wrong address, wrong chair, wrong stock count.
The order arrives automatically
WooCommerce sends it to the app as soon as the purchase is made.
One click: courier and warehouse
The app creates a shipment with the courier and a packing task. It checks the address against a database of 97,510 streets.
Scan instead of checking by eye
The packing task stays open until the correct model, color and quantity have been scanned.
Tracking and updates
The customer receives a shipment number, a receipt and an invitation to review the purchase.
Stock updates itself
Stock is tracked by component, with reservations for open orders.
The status is there immediately
One screen. No searching.
Packing errors have practically disappeared. The system blocks them before a package leaves.
An average day before and after the app.
4.5x the volume, with no new hires.
Total reviews on the company's Google profile.
10x as many reviews. The invitation goes out automatically, straight after delivery.
WHAT THE APP DOES
Sales, warehouse, delivery, complaints, outlet, purchasing and reports. These screens show how the Silla team uses the app every day.
WAREHOUSE
The warehouse has its own screen on a phone. It shows only today's tasks: packing, wholesale, incoming goods, returns and spare parts, each with a count of waiting tasks.
Barcode scanning is required. The app rejects the wrong model or color and leaves the task open.
The team can see who packed each order and when.
Labels for the courier print from the same app.
DELIVERY · COURIER
The app connects to the courier's API and tracks each shipment from collection to delivery. When something gets stuck, the system spots it before the customer does.
Waiting for the courier for more than 4 days? The employee responsible gets an automatic alert.
Collected but still not delivered after 4 days? The app automatically emails the courier to ask for a check.
After delivery, the customer receives a receipt and an invitation to leave a review. That's where the 1,000+ reviews come from.
Addresses stay accurate through a nightly sync with the courier's address database: 176 municipalities, 4,718 towns and villages, and 97,510 streets.
COMPLAINTS · SPARE PARTS · OUTLET
Each product has a list of components in the app: a chair is a seat, a backrest and four legs. A complaint can be resolved by sending the right part instead of a whole chair.
The complaint is linked straight to the order, the courier shipment and the customer's photos.
An employee chooses the part. The warehouse gets a task and a new courier shipment is created without entering the address again.
Returned goods with minor damage become outlet items, with their own barcode and price, and appear on the website automatically.
The outlet stock sells out. Silla doesn't write goods off.
PURCHASING · STOCK
Every purchase is tracked from the supplier order to receipt in the warehouse. Stock is recorded by component, so the app knows which orders can ship today.
Each purchase shows the supplier, items, quantities, purchase prices and expected arrival.
Stock only increases when a warehouse worker scans the goods in. The record matches what's actually there.
Orders missing a part sit on a separate 'waiting for stock' list and move forward as soon as it arrives.
The team publishes colors, photos, dimensions and prices for new products on the website from the app.
REPORTS · CONTROL
Orders, revenue, margins, deliveries and returns, and warehouse output by day and employee. It's all in the app in real time, without manual spreadsheets.
Packing statistics are available by day, month and employee.
Finances and receipts sit in the same system as orders.
Important actions wait in an approval queue. The system log keeps a record of what happened.
Wholesale and business-to-business sales appear in the same reports as online sales.
THE BIGGEST CHANGE
Before the app, every piece of information lived in someone's head, on paper or in Excel. To know what was happening, the owner had to be there. Today Veljko works from Thailand, visits trade fairs around the world and finds new products while the company grows faster than ever.
RESULTS
These are the figures Silla measures in its daily work. Rounded values are marked as approximate. Labor savings are calculated at a total cost of about 100,000 Serbian dinars a month per worker.
| Area | Before the app | Today | Difference |
|---|---|---|---|
| Orders a day | About 20 | About 90, same team | 4.5x |
| Errors | 3–8 a week: addresses, wrong chairs, stock records | Practically zero; the system blocks them | ~0 |
| Google reviews | Fewer than 100 | More than 1,000 | 10x |
| Labor costs | Work that would need 3–4 extra workers | Automated, with no new hires | About €31,000 to €41,000 a year |
| Stock write-offs | Damaged goods with no clear next step | Outlet stock sells out | 0 write-offs |
| Answering a customer's status query | Up to 15 minutes of searching | Immediately, on one screen | Immediate |
| The owner's role | Has to be at the company | Runs the company from abroad | 1 click |
What that means in money: the work the app does today would need 3–4 extra workers. Automating it saves about €31,000 to €41,000 a year. The app paid for itself in the first month of operation.
HOW I BUILT IT
Week 1
I mapped every step from order to complaint with the people doing the work each day.
Week 2
I connected WooCommerce, the courier's API, barcodes and product component lists.
Week 3
I built the warehouse screen, scanning, shipment tracking and automatic emails.
Week 4
Complaints, outlet, purchasing and reports went into use. The team stopped using paper and Excel.
The screens on this page are faithful mock-ups of the Silla app. Customer names and order, shipment and purchase numbers are invented to protect data.
