Cartlum – Cart Recovery, Fake Order Protection & Automation for WooCommerce

For WooCommerce stores where customers check out with a phone number and pay cash on delivery. Most of these customers never read email, many carts are left half-way, and some orders are fake. Cartlum does three jobs:

1. Cart recovery: saves the cart the moment a phone number is typed, then helps you win it back by SMS, call, WhatsApp and email.
2. Fake order protection: confirm every new order in a tap, block numbers that keep cancelling, ask risky buyers for an SMS code.
3. Easy automation: order SMS, tracking, review requests and reminders that run by themselves, and a store ChatGPT and Gemini can sell from.

Free and open source. Bangla included. A paid Pro add-on adds couriers, offers, landing pages and AI (see below).

Download

⬇ Download the latest version: on the release page, download the file named cartlum-x.y.z.zip. Don't use "Source code".

Install

1. In WordPress, go to Plugins → Add New → Upload Plugin.
2. Choose the cartlum-x.y.z.zip file you downloaded and click Install Now, then Activate.
3. Open Cartlum in the admin menu and follow Set up Cartlum (5 minutes). Under Integrations → SMS, choose your SMS gateway (eSMS, BulkSMSBD, SSL Wireless, Alpha SMS, MiMSMS, Twilio or any HTTP SMS API) and send yourself a test SMS.

To update, upload the new zip the same way and choose Replace current with uploaded. Your settings and carts are kept.

Requires WordPress 6.2+, WooCommerce 8.0+ and PHP 7.4+.

Today: what needs you, on one screen

• Needs you now: carts to call, orders to confirm, parcels to send, risky orders and cancellations without a reason, each with the button that starts the job.
• Results for 7, 30 or 90 days: money recovered, recovery rate, money still waiting and carts saved, each with its change and trend; money recovered per day as a chart (hover a day, or show it as a table); where every abandoned cart went.
• Waiting for you: the people to contact now, with call and WhatsApp one tap away. What works: which channel brings carts back.

1. Cart recovery

Every saved cart	One cart: contact and history

Save-cart popup	Reminder email	Phone-first checkout

• Saves the cart as the phone number is typed, on the classic checkout, the block checkout and CartFlows, before "Place order".
• Save-cart popup: asks for the number when a shopper is about to leave, or right after "Add to cart".
• SMS through eSMS, BulkSMSBD, SSL Wireless, Alpha SMS, MiMSMS, Twilio or any HTTP SMS API; WhatsApp with the message written; designed reminder emails; a call list for staff.
• One-tap cart link that refills the cart and opens checkout; one-time coupons only when you offer one.
• An automatic reminder with quiet hours, a daily SMS limit and a test mode.
• Honest numbers: an order counts as recovered only if you contacted the customer first.

2. Fake order protection

Orders to confirm	Risky orders

• Orders to confirm: every new order in one list, oldest first, with the customer's history. Call or WhatsApp, then one tap: Confirmed, No answer, Call back, Cancel with a reason, or Fake (and block the number).
• Protection: block numbers, IP addresses (and ranges) and devices; repeat-order and daily limits; a bot trap; an SMS code for risky orders.
• Phone-first checkout: mobile number first, then name, address and district. Bangla digits are accepted and Bangladeshi numbers checked.
• Cancellation reasons and a Reports page that shows delivery success, returns and fake orders stopped.

3. Easy automation

Order tracking	Review request	Log in with a phone number

• Order SMS at each step of the order, and a tracking bar in My Account with the courier's status.
• Review requests by SMS: a private link to rate each product, no login; answers become "verified owner" reviews.
• Log in with a phone number and an SMS code; every order placed with that number appears in My Account.
• Order again: one tap puts an earlier order back in the cart with the checkout filled in, from My Account or from {reorder_link} in an SMS.
• Sell through AI assistants: ChatGPT, Gemini, Claude, Grok, Perplexity and Kimi can read your shop (/llms.txt, a product feed, delivery and return times in each product's data) and send buyers to your checkout with an order link. Orders from AI assistants are counted in Reports.
• Webhooks for Zapier, Make and Pabbly, and CSV export.

Built around your day

Cartlum's admin is organised by a shop's daily work: Daily work (Today, Abandoned Carts, Orders, Fake Orders, Reports), Sell more (Offers and Landing pages, with Pro) and Setup (Checkout & Buttons, AI, Integrations, Settings). The menu shows how many carts to call, orders to confirm and risky orders are waiting.

• Integrations keeps every outside service in one place, each with its status, keys and a test button.
• Find a setting (Ctrl K / ⌘ K) jumps straight to any option. Switches and plain words, with technical options under More options.
• Set up Cartlum in 5 minutes, and a বাংলা button for Cartlum's screens in Bangla.
• Works on a phone: every screen at 360px, with the menu as a strip at the top.

Quantity offers: "Buy 2, save ৳100" and "Buy 1, get 1 free", applied in the cart by themselves		✅
Recommendations: "Customers also bought" under each product, learned from your own orders; the upsell can pick its product from them		✅
Upsell after the order: one tap adds a product to the same cash-on-delivery order and parcel; a second offer if they say no		✅
Loyalty points: earned when an order is delivered, spent at checkout after phone login		✅
Gift cards: sold as a product or given by hand, code by SMS, balance kept on the card		✅
Product landing pages: a one-product page for your ads with the checkout on the same page		✅
Customers confirm their own order from a link in the "order received" SMS		✅
Staff phone app: orders to confirm and carts to call, with new-order notifications		✅
Cartlum fraud network: how a number did at other shops (hashed, opt-in)		✅
Reports by district and by product		✅
Updates and support with a licence key		✅

Each Pro feature connects with the store's own accounts (SMS gateway, ElevenLabs, FraudBD, Meta). You pay those services directly; Cartlum adds nothing on top.

Sell more on every order

Landing page for your ads	Its order form	Offer after the order

• Landing pages (/lp/<name>/): headline, photos, video, benefits, reviews and questions, then your real checkout on the same page. Cart capture and fake-order protection work there too. Colour and quantity are buttons, and quantity offers show in the total.
• Upsell after the order: "Wait! Add this to your order?" One tap adds it to the same cash-on-delivery order, so nothing is charged twice and it ships in the same parcel.
