The back office behind e-commerce brands.
Built where it's hardest: cash on delivery.
I build and run the system that turns cash-on-delivery orders into delivered parcels and real margin — confirmation, address checks, carriers, customer messages, reconciled cash.
Real numbers from real operations.
Measured across two cash-on-delivery operators over twelve months. Figures are shown as ranges on purpose — this is what the system holds in production, not a single lucky month.
In cash on delivery, margin leaks between the order and the doorstep.
Every step that isn't handled quietly eats the margin you already paid to advertise for.
Customers forget and refuse the parcel
A COD order isn't paid yet. Without a fast confirmation, the customer cools off and the carrier brings it back.
Wrong address, failed delivery
A typo in the street or phone number turns into a return, a second shipping fee, and no revenue.
The carrier bill doesn't match reality
Returns, COD fees and settlements pile up. Without reconciliation, you read revenue that was never collected.
No one follows up at the right moment
Preparation, shipping and delivery messages have to go out automatically, in the customer's language, or they don't go out at all.
One pipeline, from order to collected cash.
- 01
Capture & sync
Every order from the stores lands in one place, deduplicated, in real time.
- 02
Confirm
The customer confirms fast — by call, message or form — before anything ships.
- 03
Validate the address
Street and phone are checked and corrected so the parcel actually arrives.
- 04
Route to the carrier
Each order goes to the right carrier and warehouse, with live status sync.
- 05
Track & message
Preparation, shipping and delivery emails and SMS go out automatically, per country and language.
- 06
Reconcile the cash
Carrier settlements, returns and COD fees are matched so the margin you read is the margin you keep.
A multi-store COD operator, 5 stores across 10 countries.
Built for two cash-on-delivery e-commerce operators. Their figures can be shown; their names, stores and customers cannot.
Three ways to put this to work.
No fixed price list — every operation is different. Each path starts with a short call and a written quote.
A back office built for your stores
I build the pipeline around how you actually sell: confirmation, carriers, messages, reconciliation. You own the code.
COD Manager, ready to run
The platform I run these operations on, set up for your brand. Orders, carriers, messaging, margin and stock in one place.

You work directly with the engineer who builds your system.
I'm Paul, the founder of SmartFlow. I don't hand you to an account manager. I design the pipeline, write the code and run it in production, the same way I run it for the operators above.
Based between Europe and the Gulf, working across both time zones. E-commerce first, with cash on delivery as the specialty — but the same back office works for classic prepaid stores too.
What people ask before we start.
Do I own the system you build?
Yes. For a custom build, the code is yours. COD Manager is the hosted software option when you'd rather run the platform as-is.
Which countries and carriers do you cover?
The system runs today across 10 countries in Europe and the Gulf, with multiple carriers. New carriers are added as adapters when you need them.
Do you only do cash on delivery?
COD is the specialty because it's the hardest. The same back office — confirmation, carriers, messaging, reconciliation — works for classic prepaid e-commerce too.
How long does it take to get started?
An audit is fast. A custom system or a COD Manager setup depends on your stores and carriers — we scope it on the first call and quote it before anything begins.
What if we stop working together?
You keep your data and, for a custom build, your code. Nothing is locked to me.
Let's talk
Tell me where your COD margin is leaking.
Send a few details about your stores and your main problem. I'll come back with a custom quote after a short call.
