Lumo
An AI sales assistant on WhatsApp, trained on your catalogue. It recommends products, sends photos, takes orders and hands the chat to your team when it matters.
WhatsApp · AI salesThink SMS
SMS marketing for online stores: customer segments, campaigns and automated flows like cart reminders, with the revenue each one brings in.
SMS marketingEasyVat
VAT invoices for filling stations in seconds. Snap the receipt, AI reads it, and the invoice is worked out at today’s fuel prices.
VAT invoicingWhere we come from
Business in Sri Lanka isn’t like the tutorials. Customers order on WhatsApp and expect an answer tonight. Marketing that works lands by SMS, not in an inbox. And a filling station still has to turn every receipt into a proper VAT invoice.
Most software ignores all of that. We start from it. Every product we make begins with one real, local problem and is shaped around the way your customers and your staff actually work.
We work from Rattanapitiya, close to the businesses that use our products. One team designs, builds, ships and supports every one of them.
What changed
The tools got good. AI can now answer a customer, read a crumpled receipt and send the right message at the right moment, before you’ve finished your tea.
So our products lean on AI where it’s genuinely good, and keep people in charge where it matters: Lumo hands tricky chats to your team, Think SMS follows rules you set, and EasyVat lets you check every invoice before it’s final.
Answering the hundredth “is this in stock?”, reading receipts and sending cart reminders at 2am, without getting tired.
Knowing your regulars, reading a tricky supplier and deciding when a discount is worth it.
Our products are built on that line: software takes the repetition, you keep the judgment.
Our products are self-serve. Sign up, connect what you already use and switch the automation on. No custom project, no waiting months for a launch.
Create your workspace and invite your team. No project to scope, no months of setup.
Bring in your catalogue, customers or station details. Lumo and Think SMS sync with WooCommerce.
Switch on the assistant, the flows or the invoice workflow, and let the routine run itself.
Watch orders, revenue and invoices in one dashboard, and adjust as you go.
Think SMS
SMS marketing that runs itself. Think SMS turns your store’s customers into segments that keep themselves up to date, sends campaigns when you want them and runs automated flows, from cart reminders to thank-yous, then shows you the revenue each one brought in.
Open Think SMSEvery customer in one place, with their orders and activity, synced from your store.
Rule-based groups that update themselves as customers browse and buy.
Drag-and-drop journeys: a trigger, a delay, a condition, the right SMS.
Delivery, clicks and the revenue each campaign and flow brought in.
Where to start
Most businesses we meet aren’t short of ideas, they’re short of hours. The fix is rarely one big system. It’s the next level up from where you are today.
Automation has levels, and skipping them is how it goes wrong. Our products let you start where you are and climb one level at a time.
Start with one product. Add the next when it has earned its keep.
Inside every product are small jobs that run quietly in the background, so nobody has to remember to do them. A few of them:
Product photos on request
A customer asks what you have. Lumo answers from your catalogue and drops the right photos and prices into the chat.
Order follow-ups
A message the moment an order lands, and the next one when it matters, set up once in Think SMS’ flow builder.
Receipt reading
Snap a fuel receipt and EasyVat’s AI pulls out the details, ready for you to check before the invoice is final.
Catalogue sync
Lumo stays in step with your WooCommerce store, so the assistant only offers what you actually have.
Cart reminders
A friendly SMS to customers who left something in the cart, timed so it helps rather than nags.
